This paper focuses on the effects of plyometric trainings on upper extremity anaerobic power and shotspeed in 20 volunteer male handball players, who are in the men's handball team at Süleyman Demirel University. Players were randomly divided into two groups as handball training group (HTG) and plyometric training group (PTG). While HTG continued routine handball training, plyometric trainings were applied to PTG additionally for 8 weeks, 3 days a week, at least 30 minutes a day. The upper extremity anaerobic power and shotspeed tests were applied to the groups in 1st and 8th weeks of the period (Inbar et al., 1996). Data analysis was made by using comparison tests. The study reveals that plyometric trainings have positive effects on shotspeed in handball. Considering that plyometric training provides maximum contraction in the shortest time possible, it can be said that applying plyometric training in pre-season and in-season training programming may be more effective.

Many factors determine success in football. But the most important of these are the physical and physiological variables that determine the performance of football players. Meeting these physical and physiological needs is also based on training methods prepared following branch-specific neural, muscular, and metabolic parameters. In football, for some reason, sufficient time cannot be allocated to the biomotor properties that need to be developed. Different methods are put forward to eliminate the obstacles that occur. One of these methods, which was discussed in the educational system of this field, was the idea of combining different strength training. Although there are different designs on these training in the literature, the most commonly studied methods are complex and contrast training. Complex and contrast training is based on the theory of post-activation potentiation, although there are minor differences between them. These methods generally include plyometric exercise followed by a severe strength exercise. For this reason, contrast and complex training are considered by some researchers as similar training methods, while studies that claim otherwise are also found in the literature. Discussions continue in terms of training protocols and training terms which are used. These methods are investigated by experts with many different protocols when the literature is examined. Confusion in the literature also affects studies on football. Complex and contrast training protocols in football that are used to define the purpose of this study, to examine the effect on player performance, on methods to deal with developments and discussions with existing methods to evaluate the positive and negative aspects to provide a critical perspective on sensible recommendations.

The research was experimental, and data was analyzed using spss' correlation coefficient. The results revealed the positive effects of the quality of development management on the level of general and special physical fitness of highly qualified athletes of the national team who constantly train in different teams of the republic.

The present study aims to investigate the relationship between speed and isokinetic knee strength applied at different angular velocities in female volleyball players. 11 female volleyball players from the senior category volunteered in the study (meanage: 20.2±3.9 years, meanheight: 176.8±7.1 cm, meanweight: 66.6±5.7 kg). Isomed 2000 isokinetic dynamometer was used in order to measure the isokinetic strength of participants while 20 m sprint test was conducted in order to measure the speed. In measuring isokinetic strength, knee flexion and extension (H/Q) were measured separately on concentric/concentric dominant and non-dominant legs at 60°/sec angular velocity for 5 repetitions, at 180°/sec for 10 repetitions, and at 300°/sec for 15 repetitions. In data analysis, Spearman's correlation test was used for the relationship between isokinetic knee strength applied at different angular velocities and speed (p < 0.05). The highest peak torque value in participants was measured on both sides at 60°/sec angular velocity. This was followed by 180°/sec and 300°/sec angular velocities respectively. There was no significant relationship between isokinetic knee strength applied at different angular velocities and speed. In conclusion, there is not any significant relationship between speed and isokinetic knee strength in female volleyball players.

This study combines the results of studies on the effect of plyometric training on back and leg muscle strength in different places and times to reveal the overall effect sizes of these results. For this purpose, between 2000-2020 years of plyometric training method in Turkey, back and legs taken the subject of the effect on muscle strength parameters of the Council of Higher Education of the National Thesis Archive, Google and academic journals park websites postgraduate published in theses and research papers by the inclusion of studies appropriate studies are discussed. Studies that do not meet the specified criteria are excluded from this study. For the studies whose heterogeneity value is above normal, moderator analysis of training duration, sports branch and broadcast type variables were done. Comprehensive Meta-Analysis (CMA) program was used for experimental meta-analysis. According to the results of the meta-analysis data of this study, the effect of plyometric training on the back muscle strength was 0.404 in the fixed effects model; in the random effects model, it was found to be moderate with an effect size of 0.408. In the fixed effects model for leg muscle strength, 0.478; in the random effects model, it was determined that it has a moderate effect size with a moderate effect size with an effect size of 0.525. Considering the results of this study; for the development of back and leg muscle strength, plyometric training can be said to be moderately effective.

The aim of this study is to investigate the influence of lower and upper extremity strength on shot styles in tennis. 54 males and 19 females training regularly as experimental group and 24 male and 9 female volunteers as control group participated in the study. 24 training sessions were applied to the experimental group participants. Every week in a unit training, accurate and effective shot, practically forehand and backhand, was applied to the subject suitable for the technique and style by shooting 50 balls from the ball machine. The service was performed for each subject from the service point on the baseline line of the court in 20 units in one unit training. Maximum number of heart 30 to 50% of the beats were allocated for 10 min of general warming, and 70 to 80% of the maximum number of heart beats were allocated for quick strength; moreover, practices towards upper and lower extremity were applied beforehand and finger strength trainings. Voluntary participants in the control group were not subjected to any training program. Paired t-test was used for intra-group comparisons in the analysis. Two-way ANOVA was used to compare pre-test and post-test changes in groups with gender effect. Mean and standard deviation were used as descriptive statistics. Significance was determined as p [less than or equal to] 0.05. In conclusions, effective service training should be supported with a good ball thrower and effective material. Therefore, this study is important in terms of evaluating the effect of the tennis ball thrower on the performance of the athletes to correct the shoot techniques and improve their performance.

The aim of this study is to examine the effect of wrestling education on some physical and motoric parameters in high school students. 42 volunteer men aged 15-17, who received regular wrestling training, participated in the study. In the study, after all, subjects were divided into 3 groups according to age groups, body weight, height, BMI, claw, back, leg strength, 10 and 30 m sprint, flexibility, anaerobic power, fat percentage, and body circumference measurements were taken. SPSS 20.0 program was used in the statistical analysis of the data obtained, the normality distribution of the data was determined by the Shapiro-Wilk test. Descriptive statistics, One Way ANOVA was used for normally distributed data and the level of significance was taken as p<0.05. When the findings were examined, there was a significant difference between the age variable and BMI, 30m sprint, anaerobic power, shoulder and chest circumference (p<0.05), while there were no significant differences in height, weight, claw, back, leg strength, 10m sprint, flexibility, fat percentage, waist, hip and femur values (p>0.05). In conclusion, besides the effect of growth in the adolescent period in different age groups, it can be said that wrestling education has positive effects on BMI, 30m sprint, anaerobic power, and some environmental measurements.

90-95% of vitamin D which has the supreme function of regulating many metabolisms in tissues and organs, is taken from the sunlight through skin. Since wrestling is performed in sun-protected sports halls, we think that a vitamin D replacement will improve the performance of wrestlers, especially as the limited exposure to sunlight is compared to outdoor sports branches. The aim of our study is to increase the strength and endurance of male wrestlers by applying 25-Hydroxy vitamin D replacement together with general and wrestling-specific trainings for 8 weeks. 36 wrestlers participated in the study and were divided into two groups as subject and control groups. Group A (n: 18) was the exercise-subject group with a 25-hydroxy vitamin D replacement and group B (n: 18) was the exercise-control group without the vitamin D replacement applied. In the subject group, Devit-3 oral ampoule 1 ml (300,000 I.U.) replacement was applied to the wrestlers whose 25-hydroxy vitamin D levels were below 20 ng/mL. Wrestlers were pre-tested one week before the replacement. After 8 weeks, they were post-tested and their vitamin D levels were measured again. Wrestlers in the control group were tested at the beginning and end of the 8-week training program without the vitamin D supplementation. In the analysis of the data, a Wilcoxon test and Mann Whitney test (one of the nonparametric tests) was used in accordance with the distribution width when the averages of the groups were evaluated in terms of significance with each other. The values that were p < 0.05 as the significance level of the data were accepted as statistically significant and the evaluations were made accordingly. When the results of the analysis were examined, it was seen that 25-hydroxy vitamin D levels of the wrestlers increased from 13.85 ng/ml to 26.28 ng/ml after the replacement applied to the wrestlers in the subject group. It was observed that while vitamin D levels of the group increased, their aerobic endurance decreased to 132.22 ± 9.69 from 150.33 ± 20.98 (p < 0.05). Thus, their aerobic endurance improved statistically significant. No statistically significant value was obtained in the test analysis of the wrestlers in the control group. The analysis results obtained from the study showed that the 25-hydroxy vitamin D levels in athletes increased and their aerobic capacity also increased after vitamin D induction. It is possible to say that vitamin supplementation together with 8 weeks training program is more effective for athletes to improve their strength and endurance.

Soccer game or a soccer match includes functional movements that require complex muscular balance including stopping, walking, jogging, sprint with dribbling, shooting and passing (Eniseler, 1994; Boyle, 2004). Functional training contribute to the different systems of the body through functional exercises performed in different parts of the body (covering the whole body, improving universal motor skills, applied in multiple motion planes) through intensive, short and constantly changing sessions. The aim of this study was to investigate the effects of functional training on some physiological and Biomotor Abilities in elite soccer players. Athletes were randomly divided into two groups as Traditional Training Group (TTG) and Functional Training Group (FTG). For eight weeks, TTG athletes were trained five days per week for classical soccer training while FTG athletes were trained with functional training two days a week in addition to this training. Table 4 shows that the effect of pre-test from post-test and present an adjusted post-test mean and determine the difference of the adjusted post-test mean of two groups. According to the ANCOVA results, differences were not found statistically significant (p>0.05). As a result, in this study, which aimed to investigate the effects of functional training on some physiological and bio-motor properties in elite soccer players, it was determined that functional training method had a positive effect on some physiological and bio-motor properties of pre- and post-test values in soccer players, however to determine the difference of the adjusted post-test mean of two groups, ANCOVA results show that differences were not found statistically significant.

The purpose of the present study was to compare the strength values of professional footballers according to their positions before the football season. The study group consisted of 27 professional footballers of Sanliurfaspor Football Club in the 2nd League of Turkey. The mean height of the Study Group was 180.92±6.18 (cm), mean body weight was 80.18±1.5 (kg), and the mean age was 26.40±4.4 (years). The inclusion criteria for the study was being volunteers, and the necessary permissions were obtained from the players, club managers and coaches. The Precor-brand device was used to measure the differences of strengths according to the positions of the footballers. "1 RM" measurements were made from shoulder press, latt pully, leg curl, leg extension, and leg press machines in the footballers. The SPSS 24.00 Program was used in the statistical analysis of the study data. The descriptive statistics were given as mean, standard deviation, and minimum and maximum values. The normality test of the data was analyzed with the Shapiro-Wilk Test. One-Way Anova Test was used to identify the differences between the players and the positions. The significance level was determined as 0.05. According to the results obtained in the study, no significant differences were detected in strength values between goalkeeper, defender, midfielder, and striker positions (p > 0.05). As a result, among the biomotoric properties, strength is important, and quite necessary for a footballer to perform at a high level. These values obtained from 2nd League football players are important for being taken as reference values, and it can be argued that these values obtained in the pre-season prepared the basis for the lack of qualitative differences. In future studies, data that will be obtained from different league levels and training stages will lead to research being considered differently.

The aim of this study was to examine the effect of a physical education(PE) programme targeting strength and endurance development, in which the main activities were rope climbing, pull-ups, an obstacle course, 3000-m running and kickboxing, implemented over a 22-week period and for 260 minutes per week, on the physical development of students. A total of 477 students aged 19-21 (M=20.1 ± 0.8) took part in the study, during which an intensive strength- and endurance-based physical training programme was carried out with the students by experienced physical training instructors over a period of 22 weeks. In order to assess the students' physical development, weight measurement, hand grip, bent arm hang, push-up, sit-up, agility and 20-m shuttle run tests were carried out respectively as pretest and posttest. The tests were completed in two days. The obtained data were examined with paired samples t-test. The varied strength- and endurance-based activities (kickboxing, crossing obstacles, etc.) carried out with a certain intensity and over a specific period by the students made a positive contribution to the development of their strength, endurance (Vo[superscript 2] Max) and agility characteristics.

The aim of this study is to determine the effects of both static and dynamic strength trainings on oxidative stress and DNA damage in elite boxers. 19 elite male boxers participated in the study. Boxers were instructed to perform strength exercises 3 days a week for 8 weeks. Blood samples were taken before exercises (resting), after the first exercise (acute) and after 8 weeks following the last exercise (chronic). MDA, SOD, GPx and 8-OHdG levels of blood were examined. Statistical analyses were carried out using the SPSS 22 for Windows. The data were found to not be distributed normally. Thus, Friedman, Wilcoxon and Mann-Whitney U tests were used. The results were evaluated using an alpha level of .05. In the dynamic strength exercise group, there was no significance at GPx, however MDA, SOD and 8-OHdG levels decreased in 8 weeks. In static strength exercise group, although there was no significance at SOD, GPx and 8-OHdG, MDA levels decreased both after a single session and in 8 weeks. In addition, significant difference was found between dynamic and static exercise groups at SOD, GPx and 8-OHdG levels in pre-exercise and at 8-OHdG levels after 8 weeks. Dynamic strength exercises with Thera-Band are effective on MDA, SOD and 8-OHdG chronically, static strength exercises are effective on MDA both acutely and chronically. Neither dynamic nor static strength exercises are not effective on GPx both acutely and chronically.

The aim of the study was to investigate the effects of 12 weeks Pilates exercises on functional and cognitive performance in elderly people which are living in an elderly care center. Forty three elderly were randomly allocated either to Pilates group (PG, n= 21; mean age, 72.8 ± 7.84 years), which performed three session of Pilates per week for 12 weeks, or to control group (CG, n= 22; mean age, 77.7 ± 7.25 years), which no performed any exercise is except from daily works. Participants tested to handgrip strength, Berg balance scale, Functional reach test and Mini Mental State Examination Test before and after the 12 weeks of exercise. Finally, PG demonstrated improvement in all variables. However, CG has no improvement any variables. Pilates exercises led to significant improvement in functional and cognitive performance. Therefore, elderly people can apply a well-structured Pilates exercise program under Pilates instructor and physiotherapist.

This study was conducted to investigate the effect of respiratory muscle training on respiratory functions and aerobic and anaerobic strength in adolescent taekwondo athletes. Between the ages of 12-17, 32 taekwondo athletes participated in the study. Participating athletes were randomly divided into two groups as "experimental group" (n=15) and "control group" (n=17) as to similar characteristics. The experimental group was given respiratory muscle training for 30 min with an adjustable respiratory pressure device for 3 days a week through 8 weeks period. No exercise was given to the control group with the device. A 20 meter shuttle run test was performed for aerobic capacity and a vertical jump test was performed for anaerobic strength. The inspiratory pressure was measured. After the respiratory muscle training, statistically significant difference was found in the maximum oxygen consumption capacities (MaxVO2) and anaerobic strength values (p<0.05). In the measurements of respiratory function, forced vital capacity (FVC), slow vital capacity (SVC) and maximal voluntary ventilation (MVV), significant difference was found in favor of the experimental group (p<0.05). In the measurements of inspiration pressure, the results of pressure, strength, flow, volume and energy values were significantly different in favor of the experimental group (p<0.05). Respiratory muscle training increased the aerobic and anaerobic strength capacity of the experimental group in comparison with the control group. Some of the exercises that were used in the treatment of COPD are thought to facilitate the athletes? respiration control.

To assess the acute effect of strength exercises combined with EMS on blood flow and muscle stiffness using SMI and SWE. This prospective study included 20 participants. Subjects were divided into groups base on calisthenics strength training with EMS and without EMS. Rectus femoris (RF) blood flow was measured at rest and post-exercise with the vascularity index (%) and stiffness was measured in kPa mode to compare the groups. When values are compared at rest and post-exercise, all cases had significantly increased blood flow and stiffness increase in RF post-exercise (resting mean VI [%]: 1.42±0.58 and post-exercise mean VI [%]: 5.36±3.03; resting mean stiffness [kPa]: 8.85±1.38) and post-exercise mean stiffness [kPa]: 10.57±1.79). The blood flow and stiffness values in the group with EMS and exercise had greater increases than the group with exercise without EMS (p=0.007, p=0.05, respectively). Calisthenics strength training increases RF blood flow and stiffness in the acute period. SMI and SWE are beneficial and practical radiological methods that may be used to show these variations. Strength exercises using EMS may be associated with better athletic performance.

The aim of this study was to evaluate the effects of an 8 weeks neuromuscular training program (NTP) on motoric and selected basketball skills in pre-pubescent male basketball players. Twenty-four male basketball players were divided into two homogeneous groups according to pre-test results; an intervention group (n = 12, age = 10.6 ± 0.75 years) and a control group (n = 12, age = 10.8 ± 0.68 years). All players trained together as a team; however, the intervention group participated in an 8 weeks NTP two times per week, while the control group followed their regular basketball training system as guided by their coach. Motoric skills were assessed according to the results of an agility t-test, 20 meters sprint, and tests of back strength, vertical jump, standing long jump, sit and reach, and standing stork balance. Basketball skills were assessed according to shooting and dribbling tests. Significant differences were found only in vertical jump and flexibility in the control group (p<0.05), whereas significant differences were found in all motoric and shooting skills in the intervention group (p<0.05). In addition, according to pre-test and post-test analysis of variance (ANOVA) results of the motoric and basketball skill scores of the groups, significant differences revealed in favor of the intervention group in agility, back strength, long jump, flexibility, and balance (p<0.05). The present study demonstrated the significant effects of NTP, which focused on motoric and shooting skills in pre-pubescent male basketball players.

In this study, it is aimed to examine the relationship between leg strength and dynamic balance of children who have fencing training. 59 epee athletes who are 11 and 12 years old (33 11-year-old, 26 12-year-old) participated in research groups. Star Excursion Balance Test was used to determine balance performances and Baseline brand leg-dynamometer used to determine the leg strength of athletes who had fencing training. First, the Shapiro-Wilk test was used to determine if the data obtained during the study had a normal distribution. Pearson Correlation test was performed for all data displaying a normal distribution. Significance levels were taken as P<0,05 According to the research findings it was determined that there is a meaningful relationship between leg strength and balance test of athletes who have fencing training. As a result, it was seen that balance test values increase as the leg strength increases.

The purpose of this study was to compare the physical and physiological features of the traceurs with the gymnastics athletes. The study was carried out with twelve volunteer participants (traceurs=6, gymnastics athletes=6). The mean age of the traceurs was 18.67[plus or minus]1.03 years, 172.67[plus or minus]3.78 cm, body mass 62.5[plus or minus]8.94 kg and BMI was 20.98[plus or minus]2.97; gymnastics athletes was 19.33[plus or minus]1.21 years, 175.83[plus or minus]6.18 cm, body mass 65.17[plus or minus]8.06 kg and BMI was 21.11[plus or minus]2.67. Maximal oxygen utilization levels of traceurs and rhythmic gymnastics athletes were 56.13[plus or minus]3.95 ml/kg/min and 57.18[plus or minus]5.33 ml/kg/min respectively, their Illinois test times were 15.22[plus or minus]0.42 sec and 15.33[plus or minus]0.22 sec respectively, their vertical jump distances were 47.41[plus or minus]6.05 cm and 46.48[plus or minus]3.37 cm respectively, their vertical jump power values were 7252.7[plus or minus]1142.73 W and 7026.55[plus or minus]427.62 W respectively, their horizontal jump distances were 2.53[plus or minus]0.61 m and 2.48[plus or minus]0.12 m respectively, and finally, their hamstring flexion angles were determined by using goniometer as the measurement of hamstring flexibility (traceurs = 106.67[plus or minus]4.27[degree]; gymnastics athletes = 121.33[plus or minus]5.36[degree]*), and there was a significant difference between the angles hamstring flexibility of the two groups (*p<0.05). According to the results obtained from the study, it was seen that physical and physiological values obtained from two groups of athletes were very close to each other and no significant difference was observed between these two groups. This similarity can be explained by the fact that the training of these two branches does not differ as structural features. In conclusion, the learning of important performance determinants in athletes, such as aerobic power, flexibility, agility and explosive power, by the coaches and their education in this subject may enable the preparation of a better training program.

This study is intended to analyze any improvement in flexibility, balance, strength (hand, grip, arm, torso, leg) and physiological (body weight, body mass index, body fat percentage) parameters for elementary school children with no background of sport climbing in a sport climbing training they attend. The physical and physiological parameters of the subjects were measured at the outset of the study and at the end of month two. Height (H), body weight (W), body mass index (BMI), body fat percentage (BFP), Flamingo Balance Test (FBT) for balance, Sit and Reach Test (SRT) for flexibility, Standing Broad Jump (SBJ) for explosive leg power, Sit-Ups Test (SUT) to be performed in 30 seconds for abdominal strength, Bent Arm Hang (BAH) test for endurance, hand grip strength (HGS) test for grip, and 10 x 5 meter shuttle run (SR) tests for sprint speed were conducted as a part of preliminary and posttests. The subjects took part in a 90-minute sport climbing exercise on a daily basis. The results of the preliminary and posttests pointed to a significant difference of p<0.001 in body weight, body mass index, balance, flexibility, torso strength, arm strength, grip strength and sprint speed, and of p<0.005 in body fat percentage. There was no significant difference between preliminary and post test results of the students who did not take part in any sport climbing exercise. In conclusion, physical and physiological parameters of students who take up sport climbing as early as in an elementary school do improve

The aim of this study was to investigate the chronical effects of static flexibility exercises on some biomotoric and physiological parameters in the students studying in sports high schools. A total of 130 high school students, 50 of whom were female and 80 of whom were male, who were studying at Incirliova Sports High School between 9th and 12th grades, with a mean age of 15.92±1.14, a mean sports age of 7.05±3.54, a mean body weight of 58.05±9.11 kilograms, and a mean height of 1.69±0.07 centimeters participated in the study. The participants were given training on static flexibility application with pre-tests. In order to determine the chronical effect, the participants were applied a series of tests including handgrip, sit and reach flexibility, 30 seconds push-up, static balance, vertical jump and back-leg strength tests before and after the 10-week application. The data obtained from the pre-test and post-test applications performed so as to determine the motoric characteristics of the students participating in the study was evaluated by SPSS 22.0 Package Program with a significance level of 0.05 in the 95% confidence interval. Whether the data showed normal distribution was tested by Kolmogorov-Smirnov Test. Paired Sample T-test was used to test the significance of the difference between the arithmetic means of the two related groups. The frequency distributions of the students were determined in terms of gender and class levels. The minimum, maximum, mean, standard deviation and median values of the students were calculated in terms of age (year), sports age (year), body weight (kg), length (cm), and Body Mass Index (BMI). It was found that there were significant differences between the pre-test and post-test results applied to determine the motoric characteristics of the students (p<0.05). It was revealed that the post-test results of the students in terms of sit and reach flexibility and static balance performances were better than their related pre-test results. However, no significant differences were found between the pre-test and post-test results of the students in terms of back-leg strength, handgrip, push-up and vertical jump performances (p>0.05).It was determined that the 10-week static flexibility training (protocol) given to sports high school students before applied sports classes had positive effects on some biomotoric and physiological parameters.

Whole Body Vibration (WBV) is a type of exercise commonly applied as a modern exercise technique. The purpose of the present study was to examine the effects of WBV applied for 10-week on strength, flexibility and agility in taekwondo athletes. A total of 23 healthy young males participated in the present study. The athletes were separated randomly into two groups as the control group (n=11) and whole body vibration training group (n=12). The WBV training group did training 3 days a week for 10 weeks. The Control Group did not do any trainings. The hand grip strength test, vertical jump test, sit-reach test, agility t-test were applied to the WBV training group and control group before and after the 10-week WBV training. The comparisons between the groups were analyzed by using an independent sample t-test at a significance level of p<0.05. No statistically significant differences were detected between the pre-test hand grip strength, vertical jump test, sit-reach test and agility t-test results of the WBV training group and control group according to the Independent sample t test. In the post-test results, statistically significant differences were detected between the vertical jump test, sit-reach test, agility t-test however, no statistically significant differences were detected between the hand grip strength results. The intra-group comparisons were made according to the paired sample t test at a significance level of p<0.05. Although statistically significant differences were detected in the WBV training group between the pre-test-post-test, vertical jump test, sit-reach test, agility t-test values, no statistically significant differences were detected between the hand grip strength results. No statistically significant differences were detected between the hand grip strength, vertical jump, sit-reach, agility t-test pre-test and post-test results of the control group. Long-term whole body vibration training has positive strength, flexibility and agility values.

This study seeks to compare and contrast 12 to 14 years old male tennis players in terms of strength, heart rate, oxygen saturation and technical test values. A total of 15 tennis players took part in the study after filling in a parental consent form. The average age, height and weight of the male tennis players were found to be 13.1 ± 1.06 years, 154.07 ± 5.04 cm, 36.5 ± 3.85 kg respectively. In comparing of the values, the preliminary test was applied in the first week while the last test was applied in the eighth week, taking anatomical adaptation into consideration. During that period, the players were exposed to a 90-minute training three days a week. Both during the pretest and the last test, the players were exposed to 30 seconds push-up, sit-up, ropeskipping, AOS Technical Test, SpO2 tests and their heart rates were measured. The values obtained were compared using "paired t test" with a statistical software. The significance level was taken as "p < 0.05". Having compared the results of the first and last tests applied to the players, statistically significant differences were found between push-up, sit-up and ropeskipping rates; AOS technical test values, resting pulse, first set of heart rate values, second set of heart rate values (p < 0.05); however, there was significant difference between the first SpO2, first set of hear rate values, second set of heart rates and second set of SpO2 with regard to the pre- and post-test. It is possible to conclude that the technical trainings applied to the players improved the biomotoric and some of the physiological properties of the players, which, by extension, enhanced the performances.

The aim of this study is to investigate the relationship between strength, flexibility and balance parameters of male basketball players with performance dimension. Sixteen elite basketball players participated in the study voluntarily. Leg and back strength, flexibility and static and dynamic balance parameters of the participants were examined. Pearson Product Moment Correlation Coefficient method was used to determine the relationship between performance values obtained from strength, flexibility and balance parameters. As a result of the analysis of the data obtained; between LS and BS (r = 0.676 p < 0.01), SBRL and SBB (r = 0.787 p < 0.01), SBLL and SBB and SBRL (r = 0.688 p < 0.01, r = 0.791 p < 0.01), DBB and SBB and SBRL (r = 0.775 p < 0.01, r = 0.752 p < 0.01), DBRL and SBB, SBRL, SBLL and DBB (r = 0.800 p < 0.01, r = 0.694 p < 0.01, r = 0.707 p < 0.01, r = 0.874 p < 0.01), DBLL and SBB and SBRL (r = 0.765 p < 0.01, r = 0.652 p < 0.01) are high related. While there was a moderate relationship between DBB and SBLL(r = 0.610 p < 0.05), DBRL and SBRL, DBB and DBRL (r = 0.588 p < 0.05, r = 0.589 p < 0.05, r = 0.566 p < 0.05), there were no relationship between FLX and LS and BS(r = 0.430 p > 0.05, r = 0.155 p > 0.05), SDI SBB and LS, BS and FLX (r = 0.341 p > 0.05, r = 0.388 p > 0.05, r = 0.274 p > Z0.05), SDSA SBRL and LS, BS and FLX (r = 0.103 p > 0.05, r = 0.347 p > 0.05, r = 0.167 p > 0.05), SBLL and LS, BS ve FLX (r = -0.027 p > 0.05, r = 0.237 p > 0.05, r = 0.022 p > 0.05), DBB and LS, BS ve FLX (r = 0.211 p > 0.05, r = 0.306 p > 0.05, r = 0.268 p > 0.05), DBRL and LS, BS and FLX (r = 0.268 p > 0.05, r = 0.433 p > 0.05, r = 0.281 p > 0.05), DBLL and LS, BS and FLX (r = 0.136 p > 0.05, r = 0.137 p > 0.05, r = 0.164 p > 0.05). As a result, it is thought that the basketball players' performance will be increased by paying attention to the content of training programs due to the sudden direction change actions of basketball, which are related to strength, flexibility and balance parameters of male basketball players.

Delivering successful performance in sports depends on physical fitness. Unless the physical and physiological structure is in accordance with the requirements of the sports branch, a high performance in sports cannot be realized fully (Çakmakçi, 2002). Therefore, it is important to define and improve performance parameters such as body composition, anaerobic-aerobic endurance, capacity and strength in boxing. Accordingly, In this study, it is aimed to examine the physical and physiological fitness parameters of tiny natioanal boxers between 11-13 years of age. The research was carried out on 12 boxing athletes between 11-13 years of age in the tiny national category in Kirikkale province. In statistical analysis, normality was understood by Shapiro-Wilk test and descriptive statistics method was used to define the data. In this study, maximum oxygen consumption capacity (VO2) maxs, lung functional volumes, hand grip strength levels and body composition measurements of boxing athletes were evaluated. The mean of (VO2) max values of the participants were measured 44.17 ± 8.45. Also in correlation analysis, a high relationship was found at (VO2) max BMR; r = -750, p = 0.01 level between maximal oxygen consumption capacity and basal metabolic rate However, in oxygen consumption capacity and body composition variables, The negatively significant level relationships were found at levels of (VO2) max; body fat percentage (FM), r = -696, p = 0.05, lean body mass (FFM), r = -666, p = 0.05; body mass index (BMI), r = -763, p = 0.01). As a result, in this study, identification and relationship were determined about performance data in physical and physiological fitness parameters of tiny elite boxing athletes and a data about this age group was created in boxing athletes for future studies.

Background: Project Fit America (PFA) curriculum was initiated in 1990 with a mission to provide opportunities for all American children to be fit with unique lessons and outdoor fitness equipment. Purpose: In this study, the physical education (PE) fitness testing scores of elementary school students were examined to determine the effect of PFA curriculum inclusion. Methods: A total of 72 (M= 31, F=41) 4th and 5th grade students participated. Students were divided into one of four groups: males experiencing (EM) or not experiencing (NEM) the PFA curriculum and females experiencing (EF) and not experiencing (NEF) the PFA curriculum. At this school, fitness testing was completed twice a year as part of regular PE assessment and included the following activities: cadence push-ups, cadence curl-ups, sit and reach, and the Progressive Aerobic Cardiovascular Endurance Run (PACER) test. Findings: The EM group showed significant increases in their post-test scores for both curl-ups (t(20) = -2.348, p = 0.029) and PACER (t(19) = -2.806, p = 0.011) while the EF group showed significant increases for average sit and reach (t(25) = -2.518, p = 0.019) only. The NEM group showed significantly greater post-test scores for curl-ups (t(9) = -2.427, p = 0.038). The NEF group showed no significant increases for any of the four tests. Conclusion: The results of this study indicate that PFA inclusion serves to improve student's physical fitness measures.

A limited number of acute whole body vibration (WBV) studies have investigated the effects of WBV treatments which were applied with different vibration frequencies and amplitude combinations on lower extremity muscle activation of well-trained athletes from different sports branches. To compare the effects of WBV on lower extremity muscle activation via Surface Electromyography (sEMG) of well-trained athletes from different sports branches (soccer, basketball and swimming) during static and dynamic squat exercises. sEMG activities of Tibialis Anterior (TA), Gastrocnemius Medialis (GM), Vastus Medialis (VM), Rectus Femoris (RF), Vastus Lateralis (VL) and Biceps Femoris (BF) muscles of 7 male soccer players, 7 male basketball players, and 6 male swimmers were recorded during WBV applied in static squat and dynamic squat positions with different frequencies (30-35-40 Hz) and amplitude (2-4 mm) combinations separated from each other by 5 min passive rest periods. Each combination was applied for 30 sec. The highest muscle activation was determined in TA of the swimmers compared to soccer players during static squat with 4mm-30Hz WBV application (p=0.027). The lowest muscle activation was also determined in VL of the swimmers compared to soccer players during static squat with 2mm-40Hz WBV (p=0.049). During dynamic squat with 4mm-40Hz WBV, the highest muscle activity was determined in RF of the basketball players compared to swimmers (p=0.030). However, dynamic squat with 2mm-40Hz WBV application gave rise to the lowest muscle activation in VL of the basketball players compared to soccer players (p=0.042). Well-trained athletes from different sports branches demonstrated different neuromuscular responses to acute WBV treatments. WBV during dynamic squatting which was applied with 4mm-40 Hz may be more beneficial in enhancing neuromuscular performance acutely for well-trained male athletes since it resulted in higher levels of muscular activation responses according to the present study.

The objective of this study is to examine the effect of menstrual cycle phases on aerobic-anaerobic capacity and muscle strength. 10 female kickboxing athletes with an average age of 21.40 ± 2.01 years; average height of 169.60 ± 6.14 cm; average weight of 63.90 ± 5.76 kg and average training age of 7.41 ± 2.10 participated in the study. On the first day, maximal strength (1RM), strength endurance, wingate anaerobic power and capacity test (WAnT) were conducted and aerobic measurements were taken the next day. The measurements were conducted in follicular phase on the days 2-3rd of menstrual bleeding, in mid-follicular phase on 8-9th days and in luteal phase on 22-23rd days. The data were analyzed with Friedman repeated measurements variance analysis. According to the results of the study, it was found that kickboxing athletes' aerobic-anaerobic capacity, 1RM, strength endurance and heart rate (HR) were not affected by follicular phase, mid-follicular phase and luteal phase (p>0.005). As a conclusion, it can be said that menstrual cycle does not influence performance parameters such as muscle strength, muscle endurance and aerobic-anaerobic capacity.

The role of flexibility on athletic performance is going on to be studied both acutely and how it affects the performance in the long-term. It is important to understand the effects of various stretching types and define the most appropriate form in order to maximize the human movement and performance. Proprioceptive neuromuscular facilitation (PNF) stretching techniques are commonly used at athletic and clinic settings with the aim of optimizing motor performance and rehabilitation in order to increase range of motion. Yet, new research results put forth that the relation between performance and stretching is not as its thought and come up to this belief with suspicion. The aim of this review is to focus on the positive effects of PNF stretching on performance and to provide the reader with the latest researches on athletic performance. The researches reveal that PNF stretching can increase athletic performance in the long-term. Besides, it is more possible to obtain and maintain the benefits of PNF techniques if they are performed accurately and consistently.

The purpose of this study is to determine the effect of suspension training on agility and strength performance in elite male basketball players. The study was carried out on Demir Insaat Büyükçekmece male U-21 basketball players who are the members of one of the U-21 teams of the Turkish Basketball Federation. 20 volunteer basketball players with age of 18,3 ± 0,3 years; the training ages of 6.5 ± 1.3 years; the lengths of 189.45 ± 7.3 cm; weights of 82.9 ± 7.8 kg and body mass index of 23 ± 1.3 were participated in the study. This group was used as both control and experimental group. Following their first tests, the group participating in the study continued their regular routine training for 6 weeks. After six weeks, the second measurements were taken. These measurements were also accepted as the last measurement of the group which was considered as the control group, while those measurements were accepted as the first measurement of the test group. Afterwards, suspension training (TRX) was performed twice a week right along with basketball training for 6 weeks. At the end of six weeks, the tests were repeated and the level of development of the test group was determined. In the study group, right and left hip flexility test, sitting down flexibility test, standing long jump test, vertical jump test, back and leg strength, T-test and 20-meter sprint tests were performed. The obtained data were analyzed in the SPSS program and descriptive statistics, Anova Test and Bonferroni correction were performed. As a result, there was a significant difference in hip flexion, jump, strength and agility tests (p <0.05). According to these results, suspension TRX training was found to have positive effects on elite male basketball players.

The purpose of this study is to analyse the effects of aerobic and anaerobic training programs applied to elite wrestlers on body mass index (BMI) and blood lipids. 20 elite wrestlers, whose average age is (experimental group; 15.20 ± 4.61, n = 10), control group; 15.90 ± 2.08, n = 10), participated in the study and they were randomly divided into two groups. Strength and endurance training programme based on "one day aerobic, one day anaerobic" principles was applied to the experimental group six days a week for eight weeks. The control group went on doing normal routine wrestling technical training. Before and after eight-week training program, BMI, Triglyceride, HDL-C, VLDL, Cholesterol, LDL blood values were taken from the experimental and the control group by body analyser. According to the results of the study, none of the blood lipid indicators of the control group did significantly changed from pretest to posttest. (p>0.05). However, HDL-C, cholesterol and LDL values from blood lipids indicators of the experimental group changed significantly from pretest to posttest. (p<0.05). There were no significant changes in body mass index (BMI), Triglyceride and VLDL. As a result, this study revealed that there was no significant difference in the control group which did exercise routinely, while the training programme with changeable type and volume made significant differences in the experimental group.In statistical analyses, paired- samples t test was used for intra-group comparisons, and independent sample t test was used for inter-group comparisons. The significance level was determined as p<0.05. For all the values, mean and standard deviation were used.

Main purpose of this study was Prediction of the performance of elite male trampolines based on body composition indices. To this aim, 45 male athletes (age 14.17 ± 2.86 yrs, athletic experience 7.22 ± 3.64 yrs and competitive experience 3.31 ± 2.44 yrs), who participated in the national trampoline team's preparation camps for participation at the 2014 Asian Games in four age categories included Children (ages 11 and 12 yrs), Juniors (ages 13 and 14 yrs), Adolescents (ages 15 to 17 yrs) and Seniors (ages 18 yrs <) were selected using targeted sampling. Variables of study included 24 body composition indices which were measured using standard procedures and instruments. Data were analyzed using Pearson correlation coefficient and multiple regression models at the 0.05 significance level. Results of study showed that, among all relationships between variables, only the relationships of the shoulder belt muscle strength (r = 0.294) with performance are statistically significant and in other cases, observed relationships were not statistically significant (p>0.05). Findings of this study suggest that, in the high competitive level of trampoline body composition indices have not predictive role in preparation programs of elite male trampolines.

The main purpose of this study was the effect of body composition and physical fitness factors on performance prediction of elite male trampolines. So, 45 male athletes, who participated in the national trampoline team's preparation camps for participation at the 2014 Asian Games in four age categories included Children, Juniors, Adolescents and Seniors were selected using targeted sampling as subjects. Variables of study included 24 body composition indices and 20 physical fitness factors which were measured using standard procedures and instruments. Data were analyzed using Pearson correlation coefficient and multiple regression models at the 0.05 significance level. Results of study showed that, the relationships of the shoulder belt muscle strength (r = 0.294) with performance are statistically significant and in other cases, there was no significant relationships (p>0.05). Results of study showed the relationships of the shoulder belt muscle strength (r = 0.294), aerobic power (r = 0.351), relative minimum anaerobic power (r = 0.256), with performance are statistically significant.and in other cases, observed relationships were not statistically significant (p>0.05). Findings of this study suggest that, in the high competitive level of trampoline body composition indices do not have predictive role in preparation programs of elite male trampolines, but physical factors have predictive role in preparation programs of elite male trampolines.

As part of the Comprehensive School Physical Activity Program, we investigated how early morning physical activity affects elementary school students' physical fitness and sociality. Seventy-five boys in 6th grade of one elementary school located in G Metropolitan City, Korea comprised the experimental group that participated in early morning physical activity for 6 months. The control group did not perform said activities. Experimental design for this study adopted pre- and post-measurement and comparison methods between groups. Collected data were analyzed with analyses of covariance and Bonferroni post-hoc tests. The experimental group showed significant differences in the improvement of cardiorespiratory endurance and muscle strength among the sub-elements of physical fitness compared to controls. They also showed significant differences in the development of sociability, activity, autonomy, stability, and dominance among the sub-factors of sociality compared to controls. We elucidated the importance of early morning physical activity performed before school, which has implications for schools' physical education programs.

Electrically evoked torque at rest (i.e., the torque produced from supramaximal stimuli applied to a resting muscle) has been shown to be related to muscle size in healthy adults, but this relationship has not been evaluated in pathological populations where atrophy is present. This study aims to evaluate the relationship between the electrically evoked torque at rest and vastus lateralis cross-sectional area (CSA) in individuals with anterior cruciate ligament (ACL) reconstruction. Eighteen individuals with ACL reconstruction participated. Quadriceps electrically evoked torque at rest was elicited bilaterally via sex-specific, standardized supramaximal triplet stimulations. Vastus lateralis CSA was measured at 50% of thigh length using ultrasound. Pearson's r and partial correlations were used to evaluate associations between outcomes. Evoked torque at rest was positively associated with vastus lateralis CSA in the ACL reconstructed limb (r = 0.865, partial r = 0.816, P < 0.01), non-reconstructed limb (r = 0.628, partial r = 0.575, P < 0.05), and side-to-side ratios (r = 0.670, partial r = 0.659, P < 0.01). These results indicate that electrically evoked torque at rest may indirectly assess side-to-side differences in quadriceps muscle size after ACL reconstruction.

In the research it was aimed to examine the effects of basic table tennis trainings, which were implemented on girls aged 10-12 for 16 weeks, on certain physical and physiological parameters. A total of 40 students, as randomly selected 20 test groups and 20 control groups at an age range of 10-12 participated in the research. These students were first applied pre-test measurement, and final test measurement was performed following application of basic table tennis trainings for 16 weeks. Statistical analysis of data was performed using SPSS 20.0 statistical package program. Mann Whitney U test was used in comparison of two variable groups, and the result being p<0.05 was considered significant when examined statistically. Statistical differences between measurements of body fat percentage, flexibility, vertical jumping, standing long jump, 30 m sprint, anaerobic strength, right and left hand grip strength, visual and audio reaction times, resting heart rate, and VC, FVC, FEV and FEV1 were found to be significant in favour of the test group (p<0.05). No statistically significant differences occurred between the two groups in height, body weight, body-mass index, maxVo2, and systolic and diastolic blood pressure values (p<0.05). Consequently, it was observed that the table tennis trainings, which were performed for 16 weeks, provided positive contributions to certain physical and physiological properties of girls aged 10-12, and improved them.

Accurate determinations of individuals' one-repetition maximum (1RM) are critical when evaluating the effectiveness of an exercise intervention involving progressive resistance training (RT). Traditional ("bottom-up"; BT) testing methods involve progressions from low to maximal loads and are commonly used in clinical and laboratory environments. Concerns about the reliability of BT testing in certain populations suggest a different technique may be more effective. Purpose: To compare the reliability and effectiveness of traditional 1RM testing to a novel technique (TDT) involving progressive load reductions and a starting intensity equal to 130% of exercisers' estimated 1RM. Method: 70 healthy adults (age = 45.03 ± 25.64 y) with diverse RT experience were randomized into a reliability testing trial (RTT; n = 33) or an optimal method trial (OMT; n = 37). Subjects in the RTT performed either TDT or BT on 3 occasions separated by = 72 hours, while subjects in the OMT performed each method once in random order on separate days. Results: No significant differences in percent coefficient of variation were observed between BT and TDT for either exercise used in the study (pneumatic seated chest press: Hedge's g = 0.25, p = 0.49; pneumatic recumbent leg press: Hedge's g = 0.12, p = 0.74). TDT was not found to produce significantly higher 1RM values than BT in any group. Conclusion: TDT does not appear to facilitate more reliable 1RM estimates than BT. Further research is needed to determine the stability of these findings across levels of exercisers' age, sex, and previous RT experience.

Purpose: The aim of this study was to propose field-based tests to estimate the anaerobic power of wheelchair basketball athletes. Methods: Eleven lower class wheelchair basketball players performed the Wingate test (WT) and two field-based tests (repeated sprints) of 15 (S-15) and 20 (S-20) meters. The WT provides data in Watts (W). The S-15 and S-20 are recorded in seconds and converted to W using the Running-based Anaerobic Sprint Test (RAST) equation. The participants also completed other field-based tests, such as right and left handgrip strength (HGS) tests and the medicine ball chest pass test. In addition, body mass and height were measured, and the body composition was estimated. The field-based tests and anthropometric measures were used to estimate WT peak power (PP) and mean power (MP) using multiple linear regressions. Results: The field-based tests underestimated the anaerobic power measured with the WT (in W). However, a linear regression model based on S-15 PP, right HGS, height, and body mass explained 76% (P= 0.040) of the WT PP variance. Another model based on S-15 MP and right HGS explained 72% (P= 0.006) of the WT MP variance. Both models had excellent reliability (ICC > 0.90). Conclusion: WT PP can be estimated using S-15 PP (W), right HGS, height, and body mass. The WT MP is predicted using S-15 MP (W) and right HGS. Therefore, a combination of field-based tests and anthropometric measures seem to be appropriate to determine anaerobic power of lower class wheelchair basketball athletes.

Sport coaches can agree that various levels of practice and play contribute significantly to the overall development of a young athlete. Coaches of young athletes need to also address issues related to strength and conditioning as part of the developmental cycle. Unfortunately, many sport coaches are not well trained in the science related to strength and conditioning and many athletes are woefully undertrained or inappropriately trained. To fully develop young athletes, all coaches need to have some basic knowledge of the science of strength and conditioning, not just fitness fundamentals. The complete development of young athletes incorporates a training system known as periodization. This process involves a systematized program of variables that are inversely proportional, meaning as one variable goes up, and the other variable goes down. In terms of sport seasons, as athletes spend more time in skill development during the in-season, strength and conditioning time should be reduced. This process is reversed in other situations where less skill development occurs then more strength and conditioning can, and should, occur. This article summarizes how coaches can implement strength and conditioning into practice sessions and what to do in the off-season to enhance sport skill development.

High-Intensity Functional Training (HIFT) has become a popular mode of exercise. HIFT is a training style that involves performance of coordinated, whole-body exercises at high relative intensities. Research has shown that there are numerous health benefits from performing HIFT. This article addresses how to incorporate HIFT into a high school physical education program, suggests some HIFT exercises that may be utilized by high school physical education teachers, offers simple program options high school physical education teachers may want to incorporate in their curriculum, provides some HIFT exercises that can be incorporated in high school, and provides practical options to overcome some potential roadblocks.

Musculoskeletal fitness is important for adults with intellectual disabilities (ID) to maintain cardiovascular fitness, functional independence, and work task performance, and to reduce the risk of chronic diseases and other disabilities. However, adults with ID typically have significantly lower musculoskeletal fitness compared with their peers without a disability. Appropriate instructional strategies are needed to facilitate their acquisition and maintenance of musculoskeletal fitness. In this study, three adults with moderate ID, aged 19-20 years, were selected to evaluate the effects of a multi-component treatment package that included a video-enhanced system of least-to-most prompts (LMP) on their acquisition of two muscle-strengthening machine exercises. Results from a multiple-baseline-across-participants single-subject design show substantive gains in correct and independent performance of steps in the two exercises during the treatment condition. The improved performance in both exercises was maintained 1 week and 2 weeks after the last treatment session and appeared to have extended to a large fitness room. The study suggests that use of the video-enhanced system of LMP as an additional or alternate type of instruction can lead to improved acquisition and maintenance of muscle-strengthening exercises by young adults with moderate ID.

Background: The cardiovascular disease (CVD) risk is high in adults with intellectual disabilities. This CVD risk can potentially be decreased with a resistance training (RT) programme at vigorous intensity, following previous research on successful High-Intensity Training programmes. Our aim was to explore the feasibility of a vigorous RT-programme for adults with intellectual disabilities with CVD risk factors. Method: Twenty-four adults with intellectual disabilities with at least one CVD risk factor participated in a 24-week RT-programme. The training intensity was increased from novice (50%1RM) to vigorous (75%-80%1RM). Feasibility was based on the achieved training intensity at the end of the RT-programme. Results: Nineteen participants finished the RT-programme. Feasibility was good as 58% (11 out of 19) of the participants worked out at vigorous intensity at the end of the programme. Conclusions: It is feasible for the majority of adults with intellectual disabilities with CVD risk factors to exercise at vigorous intensity.

The purpose of this study was to investigate the effect of eight weeks plyometric training on anaerobic power, counter movement jumping and isokinetic strength in 15-18 years aged basketball players. This study was including 30 male Basketball players. The subjects were divided into two groups as: the experimental group (n = 15) and the control group (n = 15). The combine training (The plyometric training and techniques-tactics) was performed by the experimental group for eight weeks. The control group was performed only techniques-tactics basketball training for eight weeks. Performance measurement; WAnT anaerobic power test, 60° and 180° s-1 isokinetic leg strength: for right and left legs, multiple jumping and vertical jumping test were performed by the subject pre and post training. Within statistical analysis, the significance of differences between these groups was tested. The arithmetic mean and standard deviation were used as descriptive statistics and Shapiro-Wilk test was used for normality distribution. While comparing paired groups Wilcoxon signed rank test was performed, Mann-Whitney U test was used for comparing independent groups. Statistical significance was taken as 0.05. According to the result of comparison between groups; It was found that exercise had significantly effect on Peak Power (w/kg), Average Power (w), Average Power (w/kg) and Power Drop (w/kg) in experimental group (p < 0,05). While significant difference was found in Right leg 60° Hamstring and Quadriceps peak torch of experimental group (p < 0,05), there was no significant difference in pre- and post-training in Isokinetic leg power parameters of control group (p>0.05). In addition, significantly differences were found in free jump, 120° Squat jump and Active jump values of Vertical jump parameters for experimental group (p < 0,05).

Objective: To explore the anaerobic power and surface EMG (sEMG) of quardrocep muscle in lower extremities after single vibration training intervention. Methods: 8 excellent male long jumpers voluntarily participated in this study. Four intervention modes were devised, including high frequency high amplitude (HFHA,30Hz,6mm), low frequency low amplitude (LFLA,15Hz,3mm), high frequency low amplitude (HFLA,30Hz,3mm), and non-vibration (CON). All subjects received a knee extensor maximal voluntary contraction (MVC) test before the vibration. After the test, a 5×1 min. vibration would be carried out and the subjects were asked to pedal. Results: Peak power and average power output of the four vibration treatment methods did not reach obvious level. There was no obvious difference in root-mean-square (RMS) EMG of the dominant leg among the four treatments. The RMS EMG of the non-dominant leg of HFLA method during peak power output was much higher than that of HFHA and CON. The quotient between root-mean-square and peak power of the four groups did not reach significant level. Conclusion: Single vibration could not improve the anaerobic performance of long jumpers and HFLA might decrease the work efficiency of the non-dominant leg muscle of excellent long jumpers participating anaerobic test.

Purpose: The current study investigated the role of quadriceps and gastrocnemii size and "vastus lateralis" and "gastrocnemius medialis" muscle architecture in peak-power and time-to-peak-power exerted in an all-out Wingate test. Twenty-one amateur cyclists were recruited. Methods: Quadriceps and gastrocnemii anatomical cross-sectional area (ACSA), and "vastus lateralis" and "gastrocnemius medialis" pennation angle and fascicle length were measured using ultrasound. Relative peak-power (normalized per body mass) and time-to-peak-power were measured during a 30s all-out test. Results: Relative peak-power was correlated with quadriceps ACSA (r = 0.896, p < 0.001), gastrocnemii ACSA (r = 0.811, p < 0.001), "vastus lateralis" (r = 0.787, p < 0.001) and "gastrocnemius medialis" pennation angle (r = 0.638, p < 0.003). Multiple regression revealed that quadriceps and gastrocnemii ACSA accounted for 85% (R[superscript 2]= 0.85) of peak-power variance. Time-to-peak-power showed "very large" (r = -0.868, p < 0.001) and "large" correlation (r = -0.680, p = 0.001) with VL and GM fascicle length, respectively. Multiple regression analysis revealed that VL fascicle length explained 75% (R[superscript 2]= 0.75) of the time-to-peak-power variance. Conclusions: Quadriceps and gastrocnemii ACSA largely explained relative peak-power in an all-out Wingate test. "Vastus lateralis" fascicle length was the main predictor of the time-to-peak-power. Muscle architecture characteristics seem to be involved in the power generating capacity.

Purpose: The aim of the study was to evaluate the effects of motor imagery (MI) and action observation (AO) combined with a motor control exercises program for the lumbopelvic region. Method: Forty-five asymptomatic individuals were randomized into three groups: MI (n = 15), AO (n = 15) or control group (CG) (n = 15). The outcome measures included lumbopelvic motor control measured with a stabilizer pressure biofeedback, trunk muscle strength using a dynamometer and the perceived fatigue using a visual analogue scale. Participants were assessed at pre-intervention, at first week of intervention (mid) and post-intervention. Results: Regarding lumbopelvic motor control, we observed significant within-group differences between pre- and the mid and post-intervention assessment in AO group (p < 0.001, d > 0.80). MI and CG groups showed significant differences between pre- and post-intervention assessment (p < 0.05, d > 0.80). Regarding the direct comparison in the [delta]Mid-Pre differences between groups, only the AO group was superior to the CG with a large effect size (d > 0.80). Regarding trunk muscle strength, significant within-group differences between pre- and post-intervention assessments were observed in AO (p < 0.001, d = -1.25) and MI (p < 0.05, d = -1.00) groups. In relation to the perceived fatigue, statistically significant within-group differences were found in all groups (p < 0.05, d > 0.60). Conclusion: AO training caused faster changes in lumbopelvic motor control compared with the CG group. The AO strategy could be used as a guideline for teaching lumbopelvic motor control exercises.

Developing students who are physically literate is one of the most important aspects of physical education (PE). As teachers, we introduce students to the concepts of health and fundamental movement skills like throwing, catching and using implements to allow them the skill proficiency to pursue an active lifestyle. This article focuses on the classic hip-hinge move: the deadlift. It not only validates the methods but acts as a guide for physical educators to incorporate fundamental movement concepts using an implement into their curriculum.

This study compared the training effects of split-style Olympic lifts (SP-L) with those of squat-style olympic lifts (SQ-L). In the study, the participants (n = 33 collegiate female volleyball players) were sorted on a random basis into the SP-L group (age = 15.80 ± 1.03 years; height = 164.50 ± 3.96 cm; body weight = 60.88 ± 8.26 kg), SQ-L group (age = 15.22 ± 1.2 years; height = 167.78 ± 3.53 cm, body weight = 62.02 ± 7.20 kg), and control group (CG; age = 15.14 ± 0.38 years; height = 165.29 ± 5.25 cm; body weight = 61.32 ± 5.89 kg). The groups performed split and squat snatch and clean and jerk twice a week for 6 weeks. Analysis of variance and magnitude-based inferences determined whether there was a significant difference in the measured variables among groups. In the groups, compared with the pretraining values, a significant and positive improvement was noted in posttraining leg stiffness and time to 5-m and 20-m sprint. However, for the time to 5-m sprint, the gains in the SP-L group were better (large/d = 1.79). In addition, an increase to spike jump and change of direction in the SP-L group alone was significant for the main effect of time (p < 0.05). The results of this study indicate that SP-L are more effective for spike jump, change of direction, and time to 5-m sprint. Although the results of the study provide insights regarding the beneficial effects of training with SP-L rather than SQ-L, consolidation of the study results with the results of future studies is warranted.

Purpose: The aim of this study was to determine the changes in neuromuscular contractile properties in elite cyclists associated to the peripheral fatigue produced in a maximal incremental test in cycle ergometer. Methods: Forty-eight volunteers' well-trained male cyclists were evaluated during the competition season within a recovery microcycle. Tensiomyography was used before and after performing an incremental test until exhaustion in cycle ergometer to measure the radial muscle belly displacement of the vastus lateralis (VL), rectus femoris (RF), and biceps femoris (BF) on the dominant leg. Maximum radial muscle belly displacement (Dm), contraction time (Tc), delay time (Td), sustain time (Ts), and radial displacement velocity (Vrd) were measured. Mixed-design factorial analysis of variance was used to detect changes in the mechanical and neuromuscular characteristics after a maximal incremental exercise test. Results: The results show in the evaluated muscles a moderate-large decrease (p < 0.01, [eta]2 = 0.06-0.51) in Tc, Td, Dm, Ts, and Vrd. This decrease occurs more sharply in the BF than in RF or VL. Conclusion: An incremental effort until exhaustion produces peripheral fatigue associated with a decrease in Dm, Tc, Td, Ts, and Vrd, being more pronounced in biceps femoris than in vastus lateralis and rectus femoris. Coaches can use these changes found in the contractile properties as a reference to detect the muscle fatigue degree that certain training models pose for the cyclist.

Purpose: To compare the effects of a single bout of eccentric cycling (ECC) and eccentric cycling with blood flow restriction (ECC[subscript BFR]) on the changes in cardio-metabolic demand and indirect markers of muscle damage in healthy men. Method: Twenty-one young men (24.0 ± 3.2 y) were randomly allocated in two groups to perform a 30-min eccentric cycling bout with or without blood flow restriction. Oxygen consumption, heart rate, rate of perceived exertion and mean arterial blood pressure were monitored during cycling. Blood lactate was measured before and after cycling. Maximal voluntary isometric knee extensor strength and muscle damage were measured before, immediately after and 1-4 days after each eccentric cycling bout. Results: Oxygen consumption, heart rate, rate of perceived exertion and mean arterial blood pressure were similar between bouts. Blood lactate concentrations increased in both groups (p < 0.01), with ECC[subscript BFR] showing 60% greater blood lactate concentration than eccentric cycling (p < 0.01). Maximal voluntary isometric knee extensor strength decreased 19-7% until 48 h and decreased 16-7% until 72 h after ECC and ECC[subscript BFR], respectively. Muscle soreness and pressure pain threshold remained elevated until 72 h after ECC and until 96 h after ECC[subscript BFR]. Conclusion: These results show that ECC[subscript BFR] induces similar cardiovascular stress, greater lactate production and longer time to recover than ECC alone. Thus, BFR can be safely implemented with eccentric cycling.

Purpose: This study compared the acute effects of two different resistance training methods on heart rate variability, blood pressure, and rating of perceived exertion in patients with liver cirrhosis. Methods: Ten patients with Child-Pugh A (seven women and three men) participated in two experimental sessions, in random order: The traditional set condition consisted of three sets of six exercises performed in a sequential manner, while the paired set condition consisted of alternating sets between two exercises (three pairs of exercises). Ten repetitions were performed for each set with 70% of a 10 repetition maximum load and with 2 min rest between sets. Blood pressure and heart rate variability were assessed pre-workout and for 60 min post-workout. The rating of perceived exertion was assessed at the end of the third set for each exercise. Results: Significant alterations in heart rate variability were observed when considering the lowest value obtained during recovery, in which the SDNN was reduced in both the traditional set and paired set conditions, as well as the root mean square of standard deviation for the traditional set condition (p < 0.05). Additionally, for the paired set condition, there was a significant reduction in the HFnu band and a significant increase in the LFnu band (p < 0.05). Effect size showed reductions in diastolic and mean blood pressure until 30 min in a small magnitude for traditional sets. Conclusion: Similar cardiovascular responses were observed between methods eliciting normal physiological responses within safe limits for patients with liver cirrhosis.
