Background: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has posed a threat to society worldwide. The aim of the study was to analyze changes in the physical fitness of 11- to 15-year-olds during the COVID-19 pandemic. Methods: Cross-sectional research was conducted in randomly selected schools in Kraków (Poland) during the years 2020 and 2022. The study group included 1635 adolescents aged 11–15 years. The results of fitness tests such as flexibility, standing broad jump, handgrip strength, overhead medicine ball throw, shuttle run (10 × 5 m), and 30-second sit-ups were analyzed. Body height and weight measurements were also taken. The standing broad jump and handgrip strength were normalized. A statistical analysis was performed to compare the differences between groups using 2-way analysis of variance with the Tukey HSD post hoc test or Kruskal–Wallis test. Results: The test results revealed a deterioration decrease in sit-ups, standing broad jump, shuttle run, and normalized standing broad jump in both sexes. Furthermore, the test results among girls showed a decrease in overhead medicine ball throw and flexibility. An increase in test results of both sexes was noticed in handgrip strength of the right and left hand. Among boys in 2022, the results were better in the flexibility test and overhead medicine ball throw compared with their peers from 2020. Conclusion: This study indicates a decrease in overall physical fitness in adolescents. The observed results may be associated with a decrease in physical activity, changes in nutrition, and restrictions imposed during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Background: This study attempts to analyse physical fitness and basic anthropometric parameters of children and adolescents participating in the nationwide physical activity promotion programme "Athletics for All!" (AFA). The programme aims to establish a national system for diagnosing, selecting, recruiting, and identifying talents in youth training. It also aims to build a career development path for athletics, forming the basis of a new structure for youth training in Poland. The primary goal of this study was to assess physical fitness of AFA participants over the years of its implementation (2015–2022) and to identify the leading motor ability with consideration for age, gender, and body build parameters determined with Body Mass Index and Ponderal Index. Methods: Nationwide measurements of basic anthropometric parameters as well as physical fitness tests were conducted among 31,790 girls (F) and 22,260 boys (M) participating in the AFA programme. Physical fitness assessments were performed using the OSF test (3 × 10 m shuttle run, standing broad jump, 1 kg medicine ball throw, 4-minute run). Comparative analysis of OSF test results, considering gender, was conducted using the independent samples T-test. The strength and direction of correlations between variables were calculated using the rho-Spearman coefficient. Results: OSF test results were converted into points, considering age and gender. Gender was found to be a significantly differentiating factor in physical fitness of AFA participants. Among twelve- and fifteen-year-olds, statistically significant differences were observed in all analysed variables, i.e. in each of the four tests and the overall score. It was noted that the examined girls aged 11 to 17 exhibited higher levels of strength compared to their male counterparts. Statistical analysis revealed significant correlations between OSF test results and the age and body build indicators, with the strength of the correlations being negligible in most cases. Conclusions: Participants of the nationwide programme "Athletics for All!" demonstrate a high level of physical fitness, with endurance being a fundamental motor ability. Physical fitness levels show significant correlations with the anthropometric parameters of children and adolescents. The study results confirm the need and justification for implementing physical activity promotion programmes for the younger generation. [ABSTRACT FROM AUTHOR]

Background: Obesity in childhood has deleterious consequences for health while improving physical fitness can significantly reduce health risks related to high body mass index. We aimed to examine the evolution of disparities in physical fitness based on weight status among 7–15-year-olds in Slovenia between 1989 and 2019 and compare these trends across sex, age and socioeconomic status. Methods: We used annual data collected within the SLOfit monitoring system in the period between 1989 and 2019, totalling 4,256,930 participants (about 137 000 per year). We examined cardiorespiratory fitness (600-m run test), muscular fitness (60-s sit-ups, bent arm hang, and standing broad jump test) and skill-related fitness (backwards obstacle course, 60-m dash, arm plate tapping). We grouped children according to the IOTF cut-offs for BMI to those living with normal weight or excess weight and estimated changes in physical fitness over time by fitting quantile regression models separately by sex and age group, and then using segmented regression to identify the patterns of trends over time. Results: Weight-based disparities in physical fitness were large in 1989 and have further increased by 2019. The increase in disparities was generally around 5 percentiles larger in boys, and 10–15-year-olds compared to younger children. It was particularly pronounced for body core strength and speed in boys (up to 15 and 19 percentiles, respectively) and upper body strength and speed among girls (up to 13 percentiles). Most of the increase in disparities in health-related fitness accumulated during the 2010s, when the fitness of children generally improved, but much less so in children living with excess weight. Conclusions: Despite recent improvements in population fitness levels, children with excess weight seem to be left behind, which adds to existing health inequalities. Our results should encourage policymakers to redesign policies aimed at promoting physical activity and enhancing physical fitness to make them more equitable and ultimately lead to reducing inequalities in fitness.

Background: Little is known regarding the association between physical fitness and anthropometric parameters in HIV-diagnosed children and adolescents. Therefore, this study aimed to investigate the association between anthropometric parameters and physical fitness in this population. Methods: A cross-sectional study was conducted with HIV-diagnosed children and adolescents (aged 5–15 years). Body composition was assessed by anthropometric measurements and dual-energy X-ray absorptiometry, cardiorespiratory fitness by peak oxygen consumption (VO2peak), muscle strength/endurance by handgrip strength, standing broad jump, abdominal and modified push-up tests, and flexibility using the sit-to reach test. Linear regression analyses (simple and multiple) were applied to investigate the association between anthropometric parameters and physical fitness. Results: In total, 86 children and adolescents (mean age: 11.44 ± 2.20 years) participated in the study. A significant association was observed between anthropometric parameters, whereby the sum of four skinfolds could explain 69% of the fat mass percentage and 30% of VO2peak; the sum of two bone diameters could explain 70% of fat-free mass, 55% of bone mineral content, and 43% of bone mineral density; calf skinfold and subscapular skinfold tests could explain the distance of standing broad jump, and the number of modified push-ups explained 16% of the standing broad jump and 19% of the modified push-up test results. Conclusions: Adding the measurements of four skinfolds and two bone diameters to a follow-up routine can provide relevant information regarding fat accumulation, bone development, cardiorespiratory fitness, and muscle strength/endurance status in HIV-diagnosed children and adolescents, supporting decision-making and measures for the adequate development of this population.

Background: It has been reported in the literature that waist circumference (WC) was related to physical fitness in adolescents. However, the association between WC and PFI(physical fitness index), a comprehensive indicator of physical fitness, has been less studied. In addition, it is not clear whether the association between WC and PFI changes depending on altitude, ethnicity, and sex. This study further revealed the correlation between WC and PFI among adolescents in high-altitude areas and provided references for the physical and healthy development of adolescents in high-altitude areas. Methods: In this study, a total of 1705 Tajik adolescents aged 13–15 years were selected using stratified whole-population sampling. WC and physical fitness items (grip strength, standing long jump, 50 m dash, and endurance run) were assessed and a standardized method was used to calculate PFI. The association between WC and PFI was analyzed by curvilinear regression analysis. Results: The mean and standard deviation of WC and PFI for Tajik adolescents aged 13–15 years old on the Pamir Plateau in Xinjiang, China, were 68.26 ± 7.75 cm and − 2.00 ± 3.47 respectively. Comparison of PFI between groups of Tajik adolescents with different WC showed that inter-group comparisons had significant effects with effect size above 0.2. The Tajik adolescents' PFI reached its highest when WC was 61 cm for boys(-1.3207), and 60 cm for girls (-1.0556). Conclusions: The association between WC and PFI in Tajik adolescents showed an inverted "U" curve, with no sex difference. It is recommended that the WC of Tajik adolescents should be controlled between 60 and 61 cm to maintain better PFI levels. The study provides support and reference for educational policy-making and public health prevention in the Pamir Plateau in Xinjiang, China. [ABSTRACT FROM AUTHOR]

Climbing is an activity involving many major muscle groups and, therefore, it is suitable for assessing general physical fitness. The Austrian pole climbing test (APCT) was developed as a reliable and valid test for the assessment of general fitness levels in children, adolescents, and young adults. In this cross-sectional pilot study, 677 participants (aged 6 to 19 years) were assessed via the APCT. Subsequently, test quality criteria (reliability and objectivity) were assessed, and the test's validity was evaluated through comparisons with other established fitness tests (hand grip strength, standing long jump, and pull- and push-ups). Additionally, age- and gender-specific reference values were generated. The reliability (ICC2.1 = 0.97, 95%CI 0.95 to 0.98) and objectivity (ICC2.1 = 0.99, 95%CI 0.99 to 0.99) of the APCT were found to be excellent. The APCT results correlated strongly with the hand strength per kilogram of body weight (right: r = 0.58; left: r = 0.53), number of pull-ups (with upper grip: r = 0.74; with lower grip: r = 0.69) and standing long jump (r = 0.61); a moderate correlation with the push-up test was observed (r = 0.44). The APCT is reliable, objective, and suitable for children, adolescents, and young adults with an affinity for sports. It offers a novel opportunity to assess fitness without time pressure, considering the anthropometric requirements. [ABSTRACT FROM AUTHOR]

Objective: To comp+are levels of physical fitness between Ecuador and Spain and identify whether breastfeeding period, walking onset, and abdominal obesity are determinants of physical performance in schoolchildren from Ecuador and Spain. Methods: a total of 352 schoolchildren (6–12 years old) from Ecuador (n = 176) and Spain (n = 176) joined in this study. Anthropometric measures, socio-demographic characteristics, and physical fitness were evaluated. Results: Spanish schoolchildren showed better performance in handgrip strength, standing long jump, and 25 m sprint (p = 0.021; p < 0.001; p < 0.001; p < 0.001, respectively). Furthermore, Spanish children showed better cardiorespiratory fitness (p < 0.001) and a higher V O 2 max (p = 0.002) with regards to their peers. In addition, children from Ecuador and Spain showed an influence of breastfeeding period (p ranged from <0.001 to 0.043) and walking onset (p ranged from <0.001 to 0.032) on physical performance. Moreover, physical fitness components were protective factors of abdominal obesity in Ecuadorian and Spanish schoolchildren (p ranged from =0.001 to 0.049). Conclusions: Our findings revealed the influence of the infancy period and the onset of walking on children's physical performance, highlighting the importance of these factors in motor development during early childhood and also their influence in middle childhood and throughout adulthood.

Recently, there has been a tendency to decrease the results of domestic skiers, in order to solve this problem, it is necessary to change the training approach in the preparatory period before the competition. The purpose of the study Improving the physical fitness of skiers using special training tools. Materials and methods In the Russian Federation, a pedagogical experiment was conducted in the village of Korshik. It was attended by teenagers aged 13-14 who were engaged in cross-country skiing. A total of 40 children participated (20-control and 20-experimental groups). The difference between the experimental group was the use of special exercises at the preparatory stage of training. The study used control standards that show the level of physical qualities, such as pull-ups, squats, long jumps, simulated 100m lifting and 500m running. Results The children from the experimental group significantly improved their performance in the pull-up test (22.2%; p<0.05), squats (5.9%; p<0.05), long jumps on two legs (6.8%; p<0.05), 100-simulated lifting per meter (7.8%; p<0.05) and running at 500 meters (4.2 %, p<0.05). At the same time, children from the control group were unable to show significant improvements in physical fitness (p>0.05). Conclusión During the preparatory period ofskiracers, it isrecommended to include special exercises that will significantly increase the level of physical qualities. [ABSTRACT FROM AUTHOR]

Objective: The aim was to (1) estimate the relationship between physical fitness (PF) and object control fundamental movement skills (FMS), (2) identify child characteristics that relate with PF and FMS, and (3) examine associations between the school environment, PF, and FMS. Methods: The sample included 1014 Portuguese children aged 6–10 years from the REACT project. PF was assessed via running speed, shuttle run, standing long jump, handgrip, and the PACER test. Object control FMS were assessed with stationary dribble, kick, catch, overhand throw, and underhand roll. Test performances were transformed into z‐scores, and their sum was expressed as overall PF and FMS. Child‐level variables included body mass index (BMI) z‐scores, accelerometer‐measured sedentary time and moderate‐to‐vigorous physical activity, and socioeconomic status (SES). School size, physical education classes, practice areas, and equipment were also assessed. Results: Approximately, 90% of the variance in object control PF and FMS was at the child level, and 10% at the school level. The correlation between PF and object control FMS was.62, which declined to.43 with the inclusion of covariates. Older, more active, and higher SES children had higher object control PF and FMS, and boys outperformed girls. BMI was negatively associated with PF but not with object control FMS. Sedentary time and number of physical education classes were not significant predictors. Most school predictors did not jointly associate with PF and object control FMS. Conclusion: PF and object control FMS z‐scores were moderately related. Not all child characteristics were associated with both PF and object control FMS, and their effect sizes were different. School characteristics only explained 10% of the total variation in PF and object control FMS. [ABSTRACT FROM AUTHOR]

This research sought to determine whether there was a direct relationship between muscle power, muscle endurance and emergency response times among young adults. While performance capability remains an essential component for emergency teams, this study showed how some physical fitness factors might alter initial emergency response time and lessen the effects of the disaster. Engagement in preparedness exercises, particularly those emphasizing physical activity, offers advantageous health outcomes and enhances disaster response efficacy. These improvements in readiness directly impact the overall outcomes of such disasters. The sample consisted of 21 students, comprising both male and female participants of the same age. Following the American College of Sports Medicine's (ACSM) Exercise Preparticipation Health Screening Questionnaire for Exercise Professionals, the participants were separated into two groups: the physically active group and the physically inactive group. The study's main objective was to determine whether muscle power and muscle endurance of the participants could influence their fire emergency response movement time to a safe location. Additionally, the study sought to find out whether physically active participants responded more quickly than physically inactive ones. The findings of this study indicate a relationship between emergency response time and measurements of muscle endurance and muscle power. Participants who were physically active had shorter movement time to safe location (p = 0.023), performed better on the standing broad jump test (p = 0.001), and muscle endurance test (p = 0.004). Although performance ability is a key component for emergency teams, this study demonstrated how some factors of physical fitness can affect initial emergency response time and help mitigate the effects of the disaster in young adults.

Background: Limited evidence exists regarding prospective associations for physical activity (PA) and sedentary time (SED) with body mass index (BMI) and muscle strength in young children. We aimed to determine prospective associations for PA and SED with change in BMI and standing long jump over 2 and 4 years in children aged 3–5 years at baseline. Methods: A sample of 262 Norwegian children (50% girls) was followed from 2015 to 2017 and/or 2019. PA and SED (hip-worn ActiGraph GT3X+) were measured at baseline and BMI and standing long jump at baseline and at follow-ups. Multivariate pattern analysis was used to determine prospective associations between the triaxial PA intensity spectrum (0–99 to ≥15,000 counts per minute) and the change in outcomes. Results: We found significant prospective associations between the PA intensity spectrum and standing long jump at 2- (explained variance = 5.8%–7.7%) and 4-year (explained variance = 4.8%–5.6%) follow-ups. Associations were negative for SED and positive for all PA intensities. We found no associations between PA/SED and BMI. Conclusions: Our findings suggest that PA and SED can predict future lower body muscle strength but not BMI in early childhood. [ABSTRACT FROM AUTHOR]

Background: Evidence suggests that functional training (FT) positively impacts physical fitness and sports performance. However, a systematic review addressing the effects of FT on basketball players remains absent. This systematic review aims to explore the influence of FT on physical fitness and skill-related performance in basketball players. Methods: We searched six databases: Web of Science, Scopus, PubMed, China National Knowledge Infrastructure (CNKI), EBSCOhost, and Google Scholar. The search utilized a combination of keywords related to FT, physical fitness, and basketball. The Eligibility Criteria of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020) guidelines were followed in this systematic review. Results: 11 studies were ultimately included in this review, collectively recruiting 333 basketball players. These studies demonstrated that FT significantly improved muscle strength, linear speed, cardiovascular endurance, flexibility, balance, and muscular endurance. However, the effects of FT on power, change-of-direction speed, and basketball-related performance were inconsistent. Most studies showed FT significantly improves these three variables, but a small number of studies did not find positive effects of FT using specific tests including standing long jump, Sargent jump, touch high, lane agility, lateral shuffle, dribbling line drill, and free-throw tests. Conclusion: FT is an effective training method for enhancing physical fitness including muscle strength, linear speed, cardiovascular endurance, flexibility, balance, and muscular endurance. However, the effects of FT on power, change-of-direction speed, and basketball-related performance were divergent. Some tests were not improved after FT potentially due to the short program lengths and training session durations, varied athletic levels of players examined, and different foci of the FT exercises administered. The collective evidence suggests FT programs, especially the specific exercises prescribed, should be tailored to the desired training objectives. More studies investigating the effects of FT on physical fitness and basketball-related performance with established tests are encouraged in the future to expand the current evidence base.

Background: Adolescence is a distinct period that is crucial for setting the foundation for long-term health. Objective: To assess the nutritional status, physical fitness, and physical activity of adolescents. Methods: The present cross-sectional study recruited 100 adolescents purposively. Information regarding general profile and lifestyle-related factors was collected using a questionnaire. Anthropometric data such as height, weight, BMI, and body fat% were collected using appropriate equipment. Physical fitness was assessed using a battery adapted from FITNESSGRAM® and PAQ-A assessed the physical activity. Dietary intake was analysed using a 2-day 24-hour dietary recall. Result: The study revealed, 19% of the participants were overweight and 6% were obese. The majority (74%) were physically inactive and 15% had high body fat %. There was lower consumption of energy, carbohydrates, iron, and calcium, than the recommendations. Also, physical activity scores were negatively associated with macronutrient intake and trunk lift (strength and flexibility) [p < 0.05]. Data showed lower physical fitness scores. BMI and hand-grip strength was positively correlated [p < 0.05]. Push Ups (endurance) and Standing Broad Jump (power) showed a negative correlation with body fat%. Tennis ball throw and PACER (cardiorespiratory fitness) were positively associated with protein intake. A multiple regression analysis significantly showed that a unit increase in cell phone usage increases body fat% by 11.64 units. Standing broad jump increases by 38.6 cm and decreases with 28.76 cm with a unit increase in playing outside and tuitions timings respectively. Conclusion: Poor nutritional status, physical fitness, and physical activity were reported among adolescents. It is imperative to plan intervention strategies to improve the overall health of adolescents. [ABSTRACT FROM AUTHOR]

Introduction: Exercise enhances one's health and competitiveness. A strong physical fitness status can pave the way for a promising future. This study presents the time-based trends in physical fitness indicators—including height, weight, BMI, lung capacity, dash, long-distance running, and standing long jump—among medical undergraduates during their university years. Additionally, we analyzed the impact of students' physical fitness on their career paths. Method: We conducted a retrospective database study by collecting physical fitness test data and career paths information for 634 medical students from a university in southwestern China. These students graduated in 2022. The career paths included pursuits in further studies, employment, and unemployment. To detect differences in these aspects, we used the t-test and Chi-square test. Results: Our study indicates a significant declining trend in the physical fitness of medical students during their university years. The changes observed between the first and fourth tests are as follows: Weight (kg): 58.52 ± 10.48 to 60.73 ± 12.07, P < 0.00 BMI (kg/m^2): 20.79 ± 2.74 to 21.24 ± 3.06, P < 0.00 50-m dash (s): 8.91 ± 0.99 to 9.25 ± 1.11, P < 0.00 Standing long jump (cm): 187.74 ± 30.98 to 182.59 ± 32.25, P < 0.00 800-m run for females (min): 3.84 ± 0.47 to 4.48 ± 0.85, P < 0.00 1000-m run for males (min): 3.98 ± 0.63 to 4.62 ± 0.87, P < 0.00 Sit-ups for females (count): 30.39 ± 7.5 to 29.03 ± 8.82, P < 0.00 Upon analyzing the correlation between changes in physical fitness and career paths, students with stable or decreased BMI had better post-graduation outcomes compared to students with increased BMI. Conclusions: Medical students show a declining trend in physical fitness during their undergraduate years. A good physical health status is beneficial for achieving better career paths. Medical students should place greater emphasis on physical exercise during their time in school. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to examine the relationships among perceived physical literacy (PPL), knowledge of physical activity and fitness (PAF knowledge), and physical fitness. Methods: Undergraduates (N = 968, female = 414; Mage = 18.64) from a public university in central China completed a simplified Chinese version of the PPL instrument, an online test for PAF knowledge, and seven health-related physical fitness tests. The PPL includes three dimensions: (a) confidence and physical competence, (b) motivation, and (c) interaction with the environment. The fitness tests measured lung capacity, body mass index (BMI), and performances in 800 (female)/1000 (male) meters run, 50 meters dash (50 M), sit-up (female) / pull-up (male), standing long jump (SLJ), and sit-and-reach. Results: PPL and its dimensions significantly predicted six fitness test performances both in male (β: -0.42 - 0.37; p < 0.01-0.05; R2: 0.01-0.13) and female (β: -0.59 - 0.49; p < 0.01-0.05; R2: 0.03-0.13) students. PAF knowledge (β: -0.17 - 0.18; p < 0.01-0.05; R2: 0.01-0.05) significantly predicted BMI (males) and performances in 50 M (females) and SLJ (females) tests. Conclusion: To support college students' fitness development and maintenance, tailored physical activity and fitness promotion programs are needed to strengthen students' PPL and PAF knowledge.

Background and Study Aim: Physical fitness is a crucial health indicator in children and adolescents. Despite the global rise in overweight and obesity, the impact of Body Mass Index (BMI) on physical fitness remains unclear. This cross-sectional study aims to investigate: (R1) the differences in physical fitness components and physical activity levels among children according to gender and BMI, and (R2) the mediating role of physical activity in the relationship between BMI and physical fitness components. Material and Methods: The sample was made of 180 students aged 11-14 years (n=90 - male; n=90 - female) divided according to BMI cutoff in normal weight, overweight and obese. Physical fitness components were assessed with several tests: Standing Long Jump (SLJ), Medicine Ball Throw 2Kg (MBT), Shuttle Run 10x5m (10x5), and One Mile Walk Test. Physical activity levels were evaluated with a self-reported questionnaire. A two-way factorial MANOVA was conducted to assess the effects of gender and BMI on physical fitness. Additionally, a mediation analysis was performed to explore the effect of physical activity on the relationship between BMI and physical fitness. Results: Results revealed significant differences in the Standing Long Jump (SLJ), 10x5 Shuttle Run, One Mile Walk Test, and physical activity levels, with moderate to large effect sizes observed. Males demonstrated higher levels of physical fitness and physical activity levels (PAL) compared to females. Individuals of normal weight were generally more active and stronger than their overweight and obese peers. Mediation analysis revealed that physical activity completely mediates the relationship between BMI and physical fitness components. Conclusions: Results from the present study suggest that the development of physical fitness is not solely determined by BMI, but also depends on the daily practice of physical activity. Future research is needed to assess the effect of physical activity in mediating and moderating the relationship between obesity and physical fitness. [ABSTRACT FROM AUTHOR]

Physical literacy (PL) is theorized to be an important determinant of physical fitness (PF) and physical activity levels (PALs), but studies have rarely examined possible correlations between PL, PF, and PAL in preadolescent children. This study aimed to evaluate age-specific and gender-specific correlations between the affective and cognitive domains of PL (PLAC), PF, and PAL in preadolescents. Additionally, the test–retest reliability of the applied PF tests was examined. The participants were 107 children (9 to 11 years of age; 53 girls). Apart from gender and school age (third graders, fourth graders), the variables included PLAC, PAL, and PF. PF was evaluated by anthropometrics and body composition indices, sit-ups, push-ups, PACER tests, torso lifts, and broad jump. PLAC was evaluated using the PLAYself questionnaire, and the PAQ-C was used to evaluate PAL. The test–retest reliability of the PF tests was appropriate to high (ICC: 0.65–0.91). Analyses showed nonsignificant associations between PLAC and PAL in both genders and age groups. PAL was significantly correlated with PL in girls (low correlation) and fourth graders (moderate correlation). The nonsignificant associations between PLAC and PF could be a consequence of the influence of biological maturity on PF in this age group. The correlation between PAL and PLAC can be explained by the differences in physical activity habits between genders and age groups, with participation in structured physical activities (organized sports and physical education) being the most important source of PAL in girls and older children.

This study aimed to contrast the impacts of an exercise intervention using either bounce drop jump (DJ; fast stretch-shortening cycle exercise) or countermovement jump (CMJ; slow stretch-shortening cycle exercise) on measures of physical fitness in young females. A total of 23 young females (age: 19.7 ± 1.0 years, height: 159.8 ± 4.2 cm, body mass: 54.3 ± 14.3 kg) were randomly assigned to either DJ (n = 12) or CMJ (n = 11) training, which spanned 6 weeks. Pre- and posttraining assessments were conducted for 10 m and 30 m linear sprints, change-of-direction speed, CMJ, DJ (jump height, contact time, and reactive strength index), standing long jump, triple-hop distance, and isometric strength. Apart from the variance in jump technique, both interventions were standardized in terms of total repetitions, intensity, and surface type. No significant Group × Time effect was observed in any dependent variables (all p >.05). A significant time effect was observed in 10 m (p <.001, effect size [ES] = 0.70) and 30 m (p <.001, ES = 0.79) linear sprint, CMJ height (p =.012, ES = 0.34), DJ contact time (p =.012, ES = 0.34), and triple-hop distance (p =.006, ES = 0.38). Both DJ and CMJ training interventions led to comparable improvements in linear sprints, CMJ height, DJ contact time, and triple-hop distance. These findings suggest that the duration of ground contact during intervention exercises (i.e., fast vs. slow stretch-shortening cycle) did not significantly influence initial (6 weeks) physical fitness adaptations in young females. However, extending these results to highly trained groups (e.g., athletes) warrants further investigation. [ABSTRACT FROM AUTHOR]

Objectives. This study is aimed at analyzing the impact of short-term Speed Endurance Soccer Training (SEST) training on the physical performance of young soccer players. Materials and methods. The true experiment method was used in this study. The study population comprised a total of 122 individuals. Furthermore, by using random sampling techniques, a sample of 30 persons was selected with an average age of 15.2 ± 0.81 years, height 168.1 ± 4.82 cm, weight 57.85 ± 11.93 kg, and BMI 20.34 ± 3.37. Physical performance instruments included the Running Based Anaerobic Sprint Test (RAST), Yo-Yo intermittent test level 1, 20-meter sprint, and standing broad jump test. The study used the paired t-test to evaluate the effect of each group and the independent samples t-test to compare the improvement in the experimental (SEST) and control groups. Statistical significance was set at p < 0.05. Results. The paired t-test showed significant differences between the pretest and post-test in the SEST group in anaerobic (p = 0.000, Δ% = 8.4), aerobic (p = 0.000, Δ% = 7.48), and speed (p = 0.000, Δ% = 3.39) capacities. Meanwhile, there were no considerable differences in the variables for the control group. According to the independent t-test results, a significant difference in effect between the SEST group and the CTRL group was revealed. The SEST group demonstrated marked differences in anaerobic, aerobic and speed variables with a p-value = 0.000. Conclusions. The study reveals that short-term Speed Endurance Soccer Training contributes to enhancing the physical performance of soccer players. However, caution should be exercised regarding the potential risk of hamstring injury in individuals with unprepared muscles. [ABSTRACT FROM AUTHOR]

The purpose of this study was to investigate whether a dynamic warm-up either with weighted vests (WVs) or with resistance bands (RBs) may enhance the physical fitness and combat ability of kumite karate athletes. Nine male athletes (age range from 16 to 30 years), participated in this study. Athletes followed three different warm-up programs in a randomized order: (a) with their body mass only (C), (b) with a WV of 10% load of their body mass and (c) with a wearable RB of 10% tension of their body mass. Following the warm-up, athletes performed the following tests: countermovement jump (CMJ), standing long jump (LJ), punch and kick reaction time, bench press throws, T-Half test and the kick frequency test. CMJ remained unaltered following the WV and RB warm-up compared to the C. Standing long jump increased significantly following the RB warm-up compared to the C (2.2 ± 1.7%, p = 0.011). Punch reaction time was significantly shortened following the RB warm-up compared to C (−7.3 ± 5.9%, p = 0.019). No changes were observed for kick reaction time, bench press throws or the T-Half test. The kick decrement index, measured from the kick frequency test, was significantly decreased following the RB warm-up compared to the C (33.1 ± 20.2%, p = 0.011). These results suggest that an RB warm-up may significantly enhance the physical fitness and combat ability in kumite karate athletes. [ABSTRACT FROM AUTHOR]

Collaborative Learning (CL) is a group learning method that involves mutual support and assistance among individual students to achieve learning goals. The purpose of this study is to assess the effectiveness of a 14-week Physical Education (PE) class using the CL method in enhancing the physical development of 11th-grade students.Introduction. Eighty healthy students were randomly selected and divided into two groups: the experimental group with 40 students applying the CL method in PE classes, and the control group with 40 students studying PE using conventional methods. In this study, five fitness tests were used such as a 30-s sit-up test, a 30-m sprint test, a 4 × 10-m shuttle run test, a standing long jump test, and a 5-min running field test. Material and Methods. After 14 weeks of experimentation, independent t-test results indicated a significant difference in the mean values between the experimental and control groups at the threshold of p < 0.05. Paired t-test results for the mean values before and after the experiment in both groups also showed a difference, with the physical fitness growth rate of the experimental group being higher than that of the control group. Particularly, the control group exhibited a post-experiment value that had a negative significance.Results. This demonstrates that the experimental results serve as an illustration, confirming the effectiveness of the CL method in high school PE classes. Teachers should enhance the use of CL in the future to achieve higher learning goals.Conclusions. [ABSTRACT FROM AUTHOR]

The identification and prediction of athletic talent are pivotal in the development of successful sporting careers. Traditional subjective assessment methods have proven unreliable due to their inherent subjectivity, prompting the rise of data-driven techniques favoured for their objectivity. This evolution in statistical analysis facilitates the extraction of pertinent athlete information, enabling the recognition of their potential for excellence in their respective sporting careers. In the current study, we applied a logistic regression-based machine learning pipeline (LR) to identify potential skateboarding athletes from a combination of fitness and motor skills performance variables. Forty-five skateboarders recruited from a variety of skateboarding parks were evaluated on various skateboarding tricks while their fitness and motor skills abilities that consist of stork stance test, dynamic balance, sit ups, plank test, standing broad jump, as well as vertical jump, were evaluated. The performances of the skateboarders were clustered and the LR model was developed to classify the classes of the skateboarders. The cluster analysis identified two groups of skateboarders: high and low potential skateboarders. The LR model achieved 90% of mean accuracy specifying excellent prediction of the skateboarder classes. Further sensitivity analysis revealed that static and dynamic balance, lower body strength, and endurance were the most important factors that contributed to the model's performance. These factors are therefore essential for successful performance in skateboarding. The application of machine learning in talent prediction can greatly assist coaches and other relevant stakeholders in making informed decisions regarding athlete performance. [ABSTRACT FROM AUTHOR]

Objectives: Reliable measurements of health‐related fitness—cardiorespiratory endurance, muscular endurance, muscular strength, body composition, and flexibility—are imperative for understanding and tracking health‐related fitness from the preschool age. This study aimed to examine the test–retest reliability of field‐based (i.e., sit and reach [standard and back‐saver], standing long jump, grip strength); and laboratory‐based (i.e., Bruce Protocol Treadmill Test, Wingate Anaerobic Test) assessments of health‐related fitness in preschool aged children (4–5 years). Methods: Forty‐two typically developing children participated in both assessment time points separated by 2–3 weeks. All fitness assessments were administered individually and repeated in the same order by the same assessor. Heteroscedasticity was examined for each parameter. Intraclass correlation coefficients were calculated to assess test–retest reliability. Results: All parameters were homoscedastic. Test–retest reliability for the field‐based tests and Bruce Protocol Treadmill Test parameters were moderate to good. Test–retest reliability for the Wingate Test parameters were good to excellent for maximum pedal rate, peak power, and peak power/kg; mean power and fatigue measured at 10 and 30 s demonstrated moderate to excellent test–retest reliability. Conclusion: The standard sit and reach, grip strength, and short‐term muscle power from the Wingate test are reliable assessments of health‐related fitness in preschool‐aged children.

The objective of this study is to investigate the effects of functional corrective training and static stretching on the quality of movement patterns and physical fitness in college students. The study was conducted with 30 male college students from a university in Guangzhou, China. The participants were randomly assigned to either the functional corrective training group (FCT, n = 15, age = 20.93 ± 0.85, BMI = 22.07 ± 2.33) or the static stretching group (SS, n = 13, age = 20.85 ± 0.86, BMI = 21.98 ± 1.80). Two participants from the SS group dropped out due to personal reasons, leaving 13 subjects in that group. Both groups underwent a 6-week training intervention, with sessions held twice a week. The FCT group participated in flexibility training, and/or static motor control training, and/or dynamic motor control training for 10-15 min. The SS group performed static stretching exercises targeting five specific muscles, with 30 s per side and two sets. The Functional Movement Screen (FMS), body composition, sit-and-reach, standing long jump, and pull-ups were assessed before and after the intervention. Differences in FMS outcomes were analyzed using two samples of the Mann-Whitney U test. Physical fitness outcomes were analyzed using a repeated measures analysis of variance (ANOVA) with a 2 (group) × 2 (time) design. After 6 weeks of intervention, the FCT group showed statistically significant improvements in the hurdle step (Z = -2.449, p = 0.014), inline lunge (Z = -2.000, p = 0.046), rotary stability (Z = -2.309, p = 0.021), and composite scores (Z = -3.316, p = 0.001). Comparisons between groups indicated that BMI (FCT, ES = 0.04; SS, ES = -0.11), 30-m sprint (FCT, ES = 0.12; SS, ES = 0.28), body fat percentage (BF%) (FCT, ES = -0.25; SS, ES = -0.07), and sit-and-reach (FCT, ES = 0.17; SS, ES = 0.06) were not statistically significant in both the pre- and post-tests. The effect sizes of all physical fitness indicators were greater in the FCT group than in the SS group. The FCT, consisting of two sessions per week for 6 weeks, has been proven to be effective in improving the quality of movement patterns by improved stability and advanced movements. However, the improvements in physical fitness did not reach statistical significance. FMS and FCT are generally affordable and accessible for college students. College students have the opportunity to employ the FMS tool to assess potential injury risks and address them, thereby reducing the risk of injuries. [ABSTRACT FROM AUTHOR]

Research Findings: The present study aims to investigate the relationship between physical fitness and visuomotor integration in young children. A total of 242 three- to six-year-old preschoolers were randomly selected from a preschool in Shenzhen, China and their visuomotor integration and physical fitness were evaluated using the Beery Buktenica Developmental Test of Visual Motor Integration (VMI) and the preschool physical fitness test, respectively. Descriptive and standard-based analysis, t-test, analysis of variances (ANOVAs), correlation analysis, and mediation analysis were conducted using SPSS. Results showed that children with different ages had significant differences in their standing long jump and visuomotor integration ability (F = 7.56, p <.001; F = 34.36, p <.001) while gender difference was found in children's throwing (t = 4.18, p <.001). Furthermore, children's visuomotor integration significantly correlated with their 20 m fast run and throwing (r =.31 and.19, p <.01). Finally, children's performance in 20 m fast run and standing long partially mediated the relationship between age and visuomotor integration. Practice or Policy: The findigs highlighted the importance of strengthening young children's physical fitness and its relationship to their visuomotor integration. Implications for theory and practice are also included. [ABSTRACT FROM AUTHOR]

Objective: High altitude hypoxic environment has a certain negative impact on physical fitness of adolescents. We aimed to understand the physical fitness status of Tibetan adolescents in different high‐altitude areas in Tibet, China. Methods: Physical fitness items, such as grip strength, standing long jump, sit and reach, 50 m dash, 1000 m run for boys, and 800 m run for girls were tested on 3806 Tibetan adolescents by using stratified whole group sampling method in class units. The mean age of the participants was (15.51 ± 1.69) years for Tibetan males and (15.54 ± 1.69) years for females. One‐way analysis of variance (ANOVA) and other methods were used to make cross‐sectional comparisons of physical fitness performance of Chinese Tibetan adolescents in different high‐altitude regions. Results: The standing long jump scores of boys (203.37 ± 28.36) were higher than that of girls (152.97 ± 19.46) and the lowest standing long jump scores of adolescents in Shigatse region (166.39 ± 35.04). The highest level of sit and reach was found among boys (10.69 ± 5.34) in Nyingchi and the lowest level of sit and reach was found among girls (8.42 ± 5.84) in Shigatse. Shigatse region adolescents had the lowest performance in 50 m dash (9.09 ± 1.72) while the best performance in 1000 m run (266.23 ± 35.82) and 800 m run (245.40 ± 27.92). Conclusion: There is variability in the physical fitness of Tibetan adolescents in different high‐altitude regions of Tibet, China. Targeted physical fitness interventions should be carried out for Tibetan adolescents in different high‐altitude regions. The focus should be on improving the endurance quality of Tibetan adolescents in Lhasa and the lower limb muscle strength, flexibility, and speed quality of adolescents in Shigatse.

Background and Study Aim Elite handball goalkeepers undergo intensive training for reflexes and advanced techniques. They develop mental toughness to handle the pressure and responsibility at key moments of the game. Thus, they protect the goal of the team. This study aims to investigate and highlight the specific training characteristics of elite handball players specialized in the goalkeeper position. Material and Methods The best 4 goalkeepers specialized in elite handball in Romania, aged between 22 and 33 years, were selected. Specific motor tests were used: Test 1 - Jumps 15 seconds; Test 2 – Reaction speed to visual stimulus; Test 3 – Execution speed. Technical tests were used: Test specific to goalkeeper, Triangle moving, The Ten Jump, Ball throwing, Standing long jump, Passes to a fixed point; The Cooper test. To improve specific training, there were applied strategies for training optimization which include stretching for mobility, segmental muscle strength, goalkeeping specific exercises and plyometrics. The nonparametric Spearman’s correlation coefficient was used to evaluate the relationship between technical training and motor skills parameters. The statistical significance level was set at p<0.05. Results The performance of elite handball players specializing in goalkeeper position highlighted significant improvements in the Jumps 15 sec test. Contact time decreased by 0.13 seconds while the jump height increased by 0.55 cm, showing improved efficiency and power. In the Reaction speed to visual stimulus test, waiting time and reaction time decreased considerably, while the foot rising height increased. In the right and left leg Execution speed test, the differences observed reveal individual adaptations. The overall time is low in the right foot and there is a significant increase in the left foot. The nonparametric Spearman correlation analysis showed the relationship between the indices of technical fitness tests and the strength and speed motor skills. During Test 1 - Jumps 15 sec - 49 correlations were identified, of which 5.36% were statistically significant, highlighting strong connections between certain parameters. The analysis of Test 2 showed 56 correlations, but the lack of statistical significance reveals the absence of connections between the technical tests and the parameters of reaction speed manifestation. Regarding Test 3, a number of 28 correlations were identified. The lack of statistical significance suggests the absence of significant correlations between the technical tests and the execution speed. Conclusions The performances of elite handball goalkeepers show significant improvements in motor and technical skills, highlighting the effectiveness of specific training and its adaptability. The progress in jumping and reaction speed indicates essential improvements for goalkeeping success, emphasizing the necessity for personalized and holistic training. [ABSTRACT FROM AUTHOR]

The optimal intra-set rest for cluster sets (CLS) during plyometric-jump training (PJT) to improve physical fitness remains unclear. The objective of this quasi-experimental study was to compare the effects of PJT with traditional (TRS) vs. CLS structures, using different intra-set rests, on the physical fitness of healthy participants. Forty-seven recreationally active young men performed 3–5 sets of 10–12 repetitions of upper- and lower-body PJT exercises twice a week for six weeks using different set configurations: TRS group (no intra-set rest), and the CLS10, CLS20 and CLS30 groups with 10, 20 and 30 s of intra-set rest, respectively, while the total rest period was equated. Pretest-posttest measurements were carried out 48 h before and after the intervention and the rating of fatigue (ROF) was also assessed using a numerical scale (0–10 points) 20 min after the first and last (i.e., 12th) session. There was no significant difference in the mean energy intake between groups (p > 0.05). The repeated measures ANOVA revealed that all groups showed similar improvements (p < 0.05) in body mass, body mass index, fat-free mass, one repetition maximum (dynamic strength) and repetitions to failure (muscular endurance) in back squat and chest press, handgrip strength, standing long jump, 20 m sprint, 9-m shuttle run (change of direction speed), and ROF. Of note, the ROF was lower for the CLS20 and CLS30 groups, independent from the training effect. The physical fitness of recreationally active young men improved after 6 weeks of PJT involving intra-set rest intervals of 0 s, 10 s, 20 s, or 30 s. However, an intra-set rest of 20 s and 30 s seems to induce lower exercise-induced fatigue perception. [ABSTRACT FROM AUTHOR]

The aim of this study is to examine the effects of short-term karate training on some physical fitness parameters in visually impaired children aged 10-12. A total of 15 visually impaired individuals participated in the study. While the study group received karate training together with physical education lessons 1 day a week for 6 weeks, the control group only attended physical education lessons. Within the scope of the Eurofit Special Test, anthropometric measurements, long jump, medicine ball throwing, sit-up, sit-reach (flexibility), walking on the bench, and 25-meter running tests were applied to the participants. According to the research data, while there was a significant difference between the pre-post tests of the anthropometric measurements of the study group (p<0.001), no significant difference was observed in the comparison of the two groups. While it was determined that there was a significant difference between the pretest-posttest values in the Eurofit Special test parameters of the study group (p<0.005), there was no significant difference between the pre-posttest values of the control group. While there was no statistically significant difference between the pretests of Eurofit Special test measurements in which two independent groups were compared, a statistically significant difference was found in favor of the study group in all parameters in the posttest when two independent groups were compared (p<0.005). As a result of the study, it was seen that short-term karate training gave positive results on some physical fitness parameters of visually impaired individuals between the ages of 10-12.

Featured Application: Understanding and researching the characteristics of adolescent athletes can contribute to enhancing the scientific level of training and talent identification. This study examined the anthropometric measurements and physical performance characteristics of female and male throwers from different age groups (14–18 years). Additionally, correlations among specific throwing strength and anthropometric and physical performance were analyzed, and regression models were established. The study reveals that boys aged 14–18 show higher trainability in overall athletic ability that requires multifaceted development. Girls, during the same period, experienced a significant improvement in agility. Agility, speed, strength, and explosive power are crucial qualities for specialized throwing development. Purpose: The aims of this study were: (1) to profile anthropometric, physical fitness, and specific throwing strength characteristics among 14–18 years boys and girls throwers; (2) to evaluate which factors vary with age, and which correlate with specific throwing strength; (3) to identify the measured variables that best predict specific throwing strength. Methods: Anthropometric, physical fitness, and specific throwing strength of 154 boys and 104 girls, who participated in track-and-field throw (Shot put, Javelin, Discus and Hammer throw) from four age categories (U15, U16, U17, U18), were measured in September 2022. The differences and correlations in parameters among different age, sex and throwing groups were analyzed using parametric and non-parametric testing. Multivariate linear regression analysis was used to identify the variables that best explain the specific throwing strength. Results: Disparities in height between boys and girls of the same age have consistently existed, however, the dissimilarity in weight tends to diminish as they grow older. Boys and girls of identical age groups exhibit noteworthy disparities in terms of speed, agility, and jumping prowess. These disparities tend to amplify as they advance in age. Significant differences were observed among boys of different ages in Height (p = 0.038), Body Mass (p = 0.02), BMI (p = 0.025), sit and reach test (p = 0.035), standing long jump (p = 0.012), standing triple jump (p < 0.01), forward overhead medicine ball throw (p = 0.002) and the hexagon agility test (p < 0.01). No differences were found in anthropometric measurements among girls, but differences were found in the hexagon agility test (p = 0.017) and plank test (p = 0.041). Specific throwing strength exhibits variations due to differences in events, age, and gender. Additionally, physical fitness performance, especially lower limb power, linear sprint speed, forward overhead medicine ball throw and backward overhead shot throw, have a high correlation with specific throwing strength. Conclusions: These findings broaden the existing knowledge base for coaches and practitioners, enabling them to discern the distinctive attributes of track and field throwers and capture the crucial physical markers that are pivotal for nurturing the progression of track-and-field throwers. The study suggests that throwers aged 14 to 18 should strive to comprehensively cultivate their athletic abilities. [ABSTRACT FROM AUTHOR]

(1) Background: The physical fitness (PF) of hearing-impaired students has always been an international research hotspot since hearing-impaired students have difficulty in social interactions such as exercise or fitness programs. Sports interventions are proven to improve the fitness levels of hearing-impaired students; however, few studies evaluating the influence of Cha-cha (a type of Dance sport) training on the PF levels of hearing-impaired students have been conducted. (2) Purpose: This study aimed to intervene in hearing-impaired children through 12 weeks of Cha-cha dance training, evaluating its effects on their PF-related indicators, thus providing a scientific experimental basis for hearing-impaired children to participate in dance exercises effectively. (3) Methods: Thirty students with hearing impairment were randomly divided into two groups, and there was no difference in PF indicators between the two groups. The Cha-cha dance training group (CTG, n = 15) regularly participated in 90-min Cha-cha dance classes five times a week and the intervention lasted a total of 12 weeks, while the control group (CONG, n = 15) lived a normal life (including school physical education classes). Related indicators of PF were measured before and after the intervention, and a two-way repeated-measures analysis of variance was performed. (4) Results: After training, the standing long jump (CONG: 1.556 ± 0.256 vs. CTG: 1.784 ± 0.328, p = 0.0136, ES = 0.8081), sit-and-reach (CONG: 21.467 ± 4.539 vs. CTG: 25.416 ± 5.048, p = 0.0328, ES = 0.8528), sit-ups (CONG: 13.867 ± 4.912 vs. CTG: 27.867 ± 6.833, p < 0.0001, ES = 2.4677) and jump rope (CONG: 52.467 ± 29.691 vs. CTG: 68.600 ± 21.320, p = 0.0067, ES = 0.6547) scores showed significant differences. (5) Conclusions: After 12 weeks of Cha-cha dance training for hearing-impaired students, the PF level of hearing-impaired students in lower-body strength, flexibility, core strength, and cardiorespiratory endurance were effectively improved; however, there was no significant change in body shape, upper-body strength, vital capacity, and speed ability.

The COVID-19 pandemic and the imposed social distancing measures caused negative changes in physical activity levels (PALs) and physical fitness (PF) among adolescents, but the potential mediating effect of the pandemic on the association between PAL and PF is unknown. This study aimed to evaluate gender-specific associations between objectively measured PAL and indices of PF among high school adolescents during the period of the COVID-19 pandemic. The participants were 150 adolescents (101 females) aged 14–18 years; their anthropometrics were evaluated, and they were tested on PF (cardiorespiratory fitness (CRF; beep test), power (broad jump), flexibility (sit-and-reach test), and abdominal strength (sit-ups)) and PAL (using a pedometer for 7 days) during the pandemic period. A T-test was calculated to determine differences between genders. Associations between variables were evaluated using Pearson correlations. Additionally, multivariate taxonomic classification was used to sort participants into homogenous groups (clusters) according to their PF, and then analysis of variance (ANOVA) was performed to differentiate them according to PAL. For the total sample, PAL was correlated with CRF only (R = 0.25, p < 0.05), while gender-stratified correlations showed that PAL was significantly associated with CRF among girls only (R = 0.29, p < 0.05), which was additionally confirmed with multivariate cluster analysis and subsequent ANOVA. No association between PAL and PF was found for boys. The relatively low association between PAL and PF is most likely related to the mediating effect of the change in life circumstances during the COVID-19 pandemic, and limited applicability of pedometers in evaluating high-intensity PAL. Further studies in other age groups and environments are warranted. [ABSTRACT FROM AUTHOR]

The aim of the study was to examine the effect of therapeutic exercise intervention (TEI) on the gender differences in typical physical fitness tests of young individuals with intellectual impairment (II). Thirty-nine young individuals with II (22 boys, 17 girls; 18.9 ± 3.2 yrs) were examined before and after the implementation of a 3-month TEI. The examined fitness tests were the sit and reach test (SRT), the standing long jump (SLJ) and the Romberg balance test with open (RBTO) and closed (RBTC) eyes. Results revealed significant (p<.05) main effect of gender and intervention and their interaction for SLJ, but not (p>.05) for the other tests. In conclusion, longer TEI are required to provoke fitness adaptations in young persons with II. [ABSTRACT FROM AUTHOR]

Background: Overweight and obesity are defined as abnormal or excessive fat accumulation that presents a risk to health; and compared with their normal-weight peers, these individuals tend to have a lower level of self-confidence, and consequently lower physical activity adherence. Due to these self-perceived barriers, the aim of our study was to evaluate the efficacy of an online training program on self-reported physical fitness (SRPF) in children with obesity (OB). Methods: A total of 32 children with OB carried out physical fitness (PF) tests and were asked to complete the International Fitness Enjoyment Scale (IFIS) questionnaire. The physical fitness tests were the Standing Broad Jump (SBJ), the 6-Min Walking Test (6MWT) and the 4 × 10msprint test. Children participated in a 3-weekly 60-min training session through Zoom platform. Before the beginning of the training protocol, OB children were compared with normal weight (NW) ones for PF batteries and the IFIS questionnaire. Changes in performances after the training were assessed by paired Student t and Wilcoxon tests. Results: After the online training program children increased their performance in 6MWT (mean difference (MD) ? 54.93; p < 0.0001) in SBJ (MD = 10.00; p = 0.0001) and in 4 x 10 m sprint test (MD = -0.78; p < 0.0001). No differences were found in children's physical fitness perception. Discussion: Our study highlighted how a structured online training program can lead to improvements in PF of children with OB. Instead, the lack of differences in SRPF after the training suggests interesting questions to be explored on the aspects linked to self-perception. Therefore, even if our training protocol could not directly improve SRPF in children with obesity, the enhancement of their PF could be a starting point for achieving this result with a longer training period and consequently improve PA participation for children with OB.

This study examined the short (pre-post) and longer-term (post to 10 weeks post) effects of the Badminton World Federation (BWF) Shuttle Time program on fundamental movement skills (FMS) and physical fitness in Saudi boys and girls. Seventy-six children aged 9–11 years (44 boys, 32 girls; mean ± SD = 10.2 ± 0.9 years) undertook twice weekly Shuttle Time sessions for 6 weeks. Pre, post, and 10 weeks post, FMS was measured using the test of gross motor development 3 and physical fitness was measured via 10 m sprint speed, standing long jump, seated medicine ball throw, and a 6 min walk test (6MWT). There were significant improvements in FMS from pre to post (p = 0.0001) and post to 10-weeks post (p = 0.0001) for both boys and girls. Girls demonstrated a significantly greater magnitude of change in FMS. For 10 m sprint time, seated medicine ball throw, standing long jump, and 6MWT performance, both boys and girls significantly improved from pre-10 weeks post (all p = 0.001). The magnitude of change was greater pre to 10-weeks post for girls for the seated medicine ball throw, but was greater for boys for the standing long jump and 6MWT. In terms of practical applications, the BWF Shuttle Time program is feasible for administration in the Saudi context and is beneficial in developing FMS and fitness for Saudi children aged 8–12 years.

Background: Human motor skills are the sum of all motor abilities and manifestations of activity. Somatic and functional differences between women and men may affect sex-related differences in motor skills. The aim of this research was to analyse sex-related differences in the physical fitness of young people aged 16 to 18 years. Material and methods: The research comprised 194 students attending randomly selected high schools in the Rzeszów district, including 104 females and 90 males aged 16 to 18 years. The research tool was the Eurofit test battery. The Mann-Whitney U test was used in the analyses. Results: There were statistically significant differences in the following tests for all studied groups: Sit-and-Reach, Standing Broad Jump, Hand Grip, Sit-Ups, 10x5 metre Shuttle Run, Endurance Shuttle Run (p>0.05). In the group of 18-year-olds, there were statistically significant differences between sexes in the Flamingo Balance test (p=0.003), whereas between the groups of participants aged 17 (p<0.001) and 18 years (p<0.001), differences were noted in the Bent Arm Hang test. Conclusions: Females, regardless of age, are more flexible than males. In turn, males, regardless of age, are characterised by greater explosive power of the lower limbs, greater static strength, strength endurance of the trunk muscles, greater speed and agility, and cardio-respiratory endurance. In the case of 18-year-olds, females were characterised by better static balance. In 17- and 18-year-old males, functional strength of the shoulder girdle and arms was higher in males than females.

Background: To explore the cross‐sectional relationship between the body mass index (BMI) and physical fitness index (PFI) of Chinese college students. Methods: In total, 30 497 (male 16 197, 55.5%) Chinese college students aged 19–22 were tested for height, weight and five physical fitness indicators (50‐m sprint, sit and reach, standing long jump, 1000/800‐m run, pull‐up/bent‐leg sit‐up). Stratified according to age and gender, according to BMI percentile, divided into BMI < 10th Percentile (A), 10th ≤ BMI < 25th Percentile (B), 25th ≤ BMI < 75th Percentile (C), 75th ≤ BMI < 90th Percentile (D), BMI ≥ 90th Percentile (E), a total of 5 groups, and the PFI composed of 5 indicators of physical fitness was calculated according to age and gender. The comparison of PFI between different BMI groups was carried out using the effect size, and the non‐linear relationship between BMI‐Z and PFI was analyzed. Results: The relationship between BMI‐Z and PFI of male and female college students in China showed an inverted "U"‐shaped curve. With comparable BMI, PFI change was greater in males than in females. Conclusion: The relationship between BMI and PFI of Chinese college students is nonlinear. The physical fitness level of college students who are underweight or overweight and those with obesity is lower than that of normal‐weight students. [ABSTRACT FROM AUTHOR]

Background and Study Aim: The modern educational process in physical education needs to form educational competencies for a limited time. It is necessary to use modern approaches. Purpose – to determine the effectiveness of holistic and differentiated methods of study the technique of long jumps by combat sports students. Material and methods: Objects. 20 healthy first-year students of bachelor of different sports qualification, who are engaged in single combats (n = 20). Following the results of the stating experiment, the participants were divided into two groups: group A (n = 10) – students with a satisfactory level of physical fitness; group B (n = 10) – students with a high level of physical fitness. Methods: testing of physical fitness using specific field tests for long jumpers for to determine the physical fitness of combat sports students and their ranking by test groups (30 m running (s); standing long jump (cm) 5-fold jump on the take-off leg (cm); triple standing jump (cm); long Jump (cm)); record video and video analysis of the elements technique of the long jump (long jump (cm); speed of the last 5 m of running start (m/s); speed of the last 10 m running start (m/s); take-off time (m/s); tempo of the last six steps (step/s)) – in order to determine the technique of the long jump from a run; the statistics made it possible to determine the effectiveness of programs of study the technique of the long jump by comparing the indicators of the initial and repeated video analysis of the records. Approach. The impact of two study programs on long jumps with a running start of students was investigated. They learn to become coaches and are engaged in types of single combats. Programs are developed considering two approaches: 1) holistic execution of different jumps (holistic approach); 2) performing special exercises and long jump parts (differentiated approach). To form study programs, the main exercises for studying long jump techniques were chosen. Results: At the beginning of the study, the indicators of physical fitness were stated. The objects were ranked into two different groups A (satisfactory level of physical fitness) and B (high level of physical fitness) (p<0.05): 30 m running – [4,53 s (Group A); 4,39 s (Group B)]; standing long jump – [235,63 cm (Group A); 273,38 cm (Group B)]; 5-fold jump on the take-off leg – [1223.50 cm (Group A); 1270.88 cm (Group B)]; triple standing jump – [635,88 cm (Group A); 667,38 cm (Group B)]; long jump – [451,75 cm (Group A); 472,63 cm (Group B)]. After used approach, it was found that as a result of study the long jump technique using different programs, the test results significantly improved (p<0.05): long jumps – for the athletes of Group A [451,75 cm; 478,50 cm], for the athletes of Group B [472,63 ; 491,88 cm]; speed of the last 5 m of running start – for the athletes of Group A [6,41; 6,47 m/s], for the athletes of Group B [6,79 ; 6,87 m/s]; speed of the last 10 m running start – for the athletes of Group A [6,42; 6,48 m/s]; take-off time – for athletes of Group A [0,23 ; 0,21 m/s], for the athletes of Group B [0,22; 0,20 m/s]; tempo of the last six steps – for the athletes of Group A [3,01 ; 3,13 steps/s], for the athletes of Group B [3,24 ; 3,41 steps/s]. The positive impact of the developed programs on speed indicators of running start and take-off in both test groups was found. All indicators as a result of intra-group and inter-group comparison significantly differed from the beginning to the end of the research (p<0,05). The exception was indicators of take-offs, which didn’t differ significantly in groups A and B (p>0,05). Conclusion: The effectiveness of the influence of both developed training programs on the long jump technique was discovered. Despite the previous motor experience and nonspecialized sports activity, it is possible to introduce different ways of studying motor actions, which are provided by the educational program. This allows you to maximize the individual opportunities of students. The presented long jump approaches allow using the level of physical fitness of trained individuals as a basis for the formation of educational programs. This allows you to increase the motivation, curiosity, and effectiveness of training a modern specialist in physical education. The development of flexible programs for students to study in other types of track and field is necessary [ABSTRACT FROM AUTHOR]

The study undertakes a thorough review of the variables impacting the track and field athletes' unsatisfactory performance in an effort to improve their performance. It looks into how track and field athletes' training methods affect their physical performance. It also comes up with a way to measure their training progress and makes it easier to figure out how different factors affect their overall performance. Then, experiments are done to make sure that these results are true. This study also looks at the exact methods and approaches that track and field athletes use to train and improve their ability. The relationship between different training techniques and the performance outcomes in field events including the long jump, high jump, shot put, and javelin throw is carefully examined. This study tries to pinpoint the most efficient methods for realizing athletes' potential by examining the effects of various training strategies on their physical prowess, technique mastery, and overall performance. The suggested evaluation model is a useful tool for evaluating how well athletes' training programs are working. It considers a number of performance characteristics, such as technique precision, mental agility, strength, and endurance. Coaches and trainers can create training plans that are specific to each athlete's demands by a methodical analysis of these aspects, enhancing the way they perform on the field.

Background: The popularity of Tunisian tennis is on the rise, due to emerging players gaining global recognition, leading to growth and evolution in the sport. In order to optimize training and performance, coaches need valuable information on physical fitness and player profiling. Objectives: The study aimed to investigate the physical profile of Tunisian tennis players in different age groups ranging from 7 to 17 years. Methods: One hundred and one tennis players from the same team were assigned to six age groups (U9-U18); U9 (7.89 ± 0.32), U10 (8.88 ± 0.34), U11 (9.78 ± 0.43), U12 (10.81 ± 0.4), U14 (12.3 ± 0.73), and U18 (14.69 ± 0.95) and were assessed for standing long jump (SLJ), countermovement jump, medicine ball throw (MBT), various sprint distances, agility drills, 20m Shuttle run (20mSRT), and Sit and reach tests. Results: The results showed that U14 and U18 age groups demonstrated better performance than U9 and U10 in jump tests, while U18 and U14 outperformed only U9 in the MBT test. U11 showed better performance than U9 and U10 in sprints, sideways shuffle, and spider drill tests. U9 and U10 had lower performance than U12 in SLJ, 20m sprint, sideways shuffle, and zigzag tests, and U11 outperformed U9 in the SLJ test. U18 and U14 had higher VO2 max than U10 and U11, while U12 was higher than U11 only. No difference in flexibility was reported. The centile estimates of physical performances among Tunisian tennis players provide a means to compare individual player test results with the standard performance levels of the group. Conclusions: In conclusion, this study found that 11-17-year-old players exhibited greater physical performance than 7-10-year-old players. However, no age effect was found for flexibility.

Objectives: The aim of the study was to analyze the changes of the motor skills of children and adolescents from Krakow between 2010 and 2020. Methods: The group included 4106 children and adolescents (8–18 years of age). The analysis of changes included results of the following fitness tests: backwards overhead medicine ball throw, standing broad jump, dynamometric strength of the hand, flexibility test, as well as shuttle run (10 × 5 m). Results: A negative trend in both sexes was observed in the results of overhead medicine ball throw. The girls also had a negative intergenerational changes in the results of the shuttle run and the flexibility test. A positive secular trend was also observed in both sexes in relations to the dynamometric force of the right and left hand. In addition, the boys studied in more contemporary times showed better results in the shuttle run, compared to their peers in 2010. Conclusion: The study reported a decline in overall motor performance in children and adolescents. The observed results may be related to a decrease in the level of physical activity, as well as a higher incidence of overweight and high levels of body fat in the modern population.

In the past few years, the level of physical fitness in children has decreased globally. According to the SIMCE test carried out in 2015, 45% of 8th year students in Chile were overweight. Moreover, international studies have shown that being overweight is associated with the development of chronic illnesses, negatively affecting cognitive mechanisms and processes. Nevertheless, there is little to no evidence that analyzes the relationship between physical fitness and executive functions in students, at a national level. The aim was to analyze the relationship between cardiorespiratory, musculoskeletal, and motor fitness, and performance in an executive functions test, in students from a public school in the south of Chile. A qualitative, descriptive –correlational, non-experimental, and cross-sectional approach was used. In total, 100 students between 9 and 12 and 11 months of age from a public school in the south of Chile completed the physical fitness assessments through the ALPHA fitness test, and 81 students completed the executive function assessments through the ENFEN test. It was evidenced that students who achieved a longer duration of time and a later stage in the Course Navette test, more centimeters in the standing broad jump (SBJ) test, and a shorter duration in the 4 × 10 shuttle run obtained a better score in the gray trail test. Additionally, students who presented a stronger dominant handgrip scored higher in the colored trail tests. We conclude that students who show a higher level of physical fitness also present a better development of executive functions such as working memory and inhibitory control. In addition, these results suggest physical condition is a factor to consider for better cognitive and school performance. [ABSTRACT FROM AUTHOR]

Although normative data for physical fitness parameters are available at International and European level, contemporary normative scores from North-East Greece are sparse. Moreover, direct comparison of physical fitness data to European norms is still absent. Objective. This investigation aimed to evaluate the cardiorespiratory and musculoskeletal fitness of Greek preadolescents from North-East Greece in comparison to current European reference norms. Method. 300 pre-adolescent (mean Tanner stage A: 1.67 ± 0.6; mean Tanner stage B: 1.65 ± 0.6) boys and girls (mean age: 9.4 ± 1.1 years) completed a testing battery of 20-m shuttle run test (20m SRT), handgrip strength, and standing broad jump. Scores for each testing parameter were compared against European age- and sex-specific centiles and then grouped into quintiles. Results. For all testing parameters, 60-81% of participants were classified as having physical fitness performance scores of "moderate" or lower level. No differences were noted between boys and girls. Data corroborated that physical fitness levels of Greek preadolescent boys and girls are among the lowest recorded in the European region. Conclusion. This data suggest that physical fitness levels of pre-adolescents in North East Greece may be suboptimal, which strongly indicates the need for adopting large-scale fitness assessments in this particular region.
