This article reflects on an instructor's experience of incorporating an optional assignment in a theology class wherein students are invited to learn a new athletic skill, journal while doing so, and then theologically reflect on their experience. It begins with the instructor making a case for the need to bring the body back into the classroom. This is followed by the theological reflections of three of the instructor's students. Finally, the instructor reflects on the themes of balance and muscle memory, stretching, and flow developed in the student reflections. These are used to outline how a balanced classroom revives theological wonder, affirms change in a cruciform fashion, and understands failure as part of God's modus operandi and so intrinsic to theology.

Musicians who play instruments may suffer from some musculoskeletal disorders due to intense and long working processes, wrong posture-holding, insufficient bodily awareness. Preparatory physical exercises can be used to prevent or alleviate these disorders. These are aimed at warming up, opening-stretching, strengthening the joints and muscles and maintaining the correct posture in order to prepare the body for playing. In this study, it was aimed to reveal the pre-service music teacher candidates' physical exercises for instrument practice. A qualitative method was used in the research; a semi-structured interview form was applied to the study group. In the analysis of the data, the thematic analysis technique was used. As a result of the analysis, 4 main themes including "exercise experience", "breath awareness", "physical pains" and "effects of exercise" and 9 sub themes and 49 codes depending on these themes were revealed. As a result of the research, it was concluded that music teacher candidates did not do regular exercise work for instrument study, they experienced physical pain due to instrument study, their breath awareness was not at a sufficient level, and exercise had physical and psychological effects on instrument performance. In addition to medical treatments for musician injuries related to instrument playing, physical awareness and exercise training that prevent these disorders play an extremely important role. In instrument education, besides technical and musical concepts, it is necessary to research and apply ways to bring physical awareness to students.

Background: Measures that assess muscle strength and its development, either voluntarily or involuntarily, are important in the clinical and research context. The main aim of this study was to verify the interday reliability and the minimum detectable change (MDC) of the knee extensors muscles torque using evoked contractions and explosive voluntary contractions (EVC), across six different joint angles. Methods: 20 participants, 16 men and 4 women (26.5 ± 6.6 years; 174.5 ± 11.1 cm; 73.7 ± 11.3 kg), participated in this study. Evoked twitch contractions and voluntary explosive contractions of the knee extensors were performed in 2 days (test-retest) at 20, 40, 70, 90, 105 and 115 degrees. Results: The most reliable twitch parameters were peak torque (PT), contraction time (CT), half relaxation-time (½ time), total impulse and peak rate of torque development (RTD[subscript Peak]), with coefficient of variation (CV) ranging from [approximately] 8% at 20° to 5% at 115° angle. It was verified that CT and ½ time become more reliable as the knee angle changed from 20 to 115 degrees, from shorter to longer muscle lengths (7.3 to 2.7% and 8.8% to 4.0%, respectively). The more reliable parameters for voluntary contraction were PT, RTD[subscript 250 ms], RTD[subscript Peak] and impulse[subscript 250 ms] (CV from around [approximately] 8% at 20°/115° and 5% at 70°/90°). For voluntary contractions, all measures performed at 70° angle were more reliable compared to the other angles. Conclusion: It was concluded that for the knee extensor muscles, evoked twitch contractions presented greater reliability across knee angles, with lower CV values when compared to the voluntary measures for the same time windows. Specifically, for the evoked twitch contractions, angles from 70 to 115 degree proved to be highly reliable. On the other hand, for the voluntary contractions, the central angles (70 and 90 degree) were the most reliable.

The relationship between youth-fitness test items related to cardiorespiratory endurance and body composition and health outcomes is well established. Until recent years, the link between musculoskeletal fitness measures and health markers has been less conclusive. The information provided in this article offers evidence of the health links between youth musculoskeletal measures (specifically the grip test, the vertical jump, the long jump, and the plank) and health outcomes. While additional research is necessary, it is safe to say that the new research brings us closer than ever to identifying reliable, valid, practical muscle-fitness test items. Physical education teachers can consider the suggestions provided in this article for using the test items in their classes.

We investigated the associations and differences between dynamic strength index (DSI) calculated from different types of vertical jump (countermovement jump; CMJ and squat jump; SJ) and different isometric knee joint angles (30, 60 and 90[degrees]), and associations with force-velocity (FV) profile and its constituent variables (maximal theoretical force (V[subscript 0]), power (P[subscript max]) and velocity (V[subscript 0]) and the slope of the FV relationship (S[subscript fv]), on a sample of young athletes and active participants (n = 28). There were moderate associations between P[subscript max] and all DSI values (r = 0.42-0.69; p < 0.05), V[subscript 0] and all DSI values from CMJ and DSI[subscript 30] from SJ (r = 0.43-0.56; p < 0.05), while S[subscript fv] was associated only with DSI[subscript 30] and DSI[subscript 90] in CMJ (r = 0.40-0.43; p < 0.05). This suggests that DSI and FV methods provide similar information and can be used in a similar manner to direct an individual's training.

Objective: This study examined relationships between physical fitness, health behaviors, and occupational outcomes of university affiliates. Participants: 166 university affiliates of an American university (including students, faculty, and staff) participated between October 2018 and March 2020. Methods: Participants completed fitness measurements, wore a device to measure physical activity (PA) and sleep for one week, and completed a survey evaluating happiness and job satisfaction. Multiple regression models evaluated associations between physical fitness, health behaviors, and occupational outcomes. Results: 45% of participants had "poor" cardiorespiratory fitness (CRF) and unhealthy % fat. CRF, body composition, and muscular endurance were related to PA while body composition was related to sleep duration. Muscular endurance was related to GPA and job satisfaction. Conclusions: Findings suggest 45% of university affiliates had deficient physical fitness and may benefit from increasing PA and sleep. Universities should evaluate fitness within holistic programs to improve affiliates' health and, ultimately, occupational success.

Pitching velocity is a crucial factor in effective baseball pitching performance. Upper-body-focused training is prevalent in baseball training to increase pitching velocity. However, significant pitchers, including youth league baseball players, suffer from upper body injuries due to the heavy training load of the throwing arm. This article emphasizes lower-body training to increase baseball pitching velocity. Three step-by-step recommended activities, with accompanying research support, include power training in the lower limbs, exploring and maintaining optimized stride length, and timing and mechanics of pitching sequences. The suggested lower body focused training will be beneficial in increasing pitching velocity and reducing the risk of injuries in the throwing arm. These recommendations are crucial for young baseball players, youth baseball coaches, strength coaches, and parents who aim to improve pitching performance while addressing concerns about overtraining and injury prevention.

Among the body's mechanical systems that contribute to anterior cruciate ligament (ACL) injuries, hamstrings, quadriceps, and knee flexor muscles are the most prominent components. A strength imbalance to any of these muscles can cause damage to ACL-associated ligaments (Takahashi et al., 2019). To reduce the incidence of such injuries, it is critical to implement strategies that focus on strengthening these muscles evenly and increase the overall balance, flexibility, and strength of basketball players. This article will share a few exercises that can strengthen ACL-associated muscles and can be easily implemented in a typical high school training session. To increase the effectiveness of these exercises, it is recommended to use therabands.

Aim: This research aimed to analyze the vocational adjustment of paramedic students in health sciences in terms of some anthropometric and motoric features. Material and Method: The research is a cross-sectional study, which is one of the quantitative research methods aimed at paramedic students. The study group consisted of 60 (n[subscript Male]=34, n[subscript Female]=110) first-year students (n[subscript Male]=16, n[subscript Female]=44; male: 19.63±1.36 years, female: 19.57±1.15 years) receiving education at Kirsehir Ahi Evran University (KAEU) Health Services Vocational School in the First and Emergency Aid Program who agreed to participate in the research voluntarily. To determine the descriptive statistics of the study group, gender and age variables were collected through the direct data collection method. After this process, required measurements, including somatotype measurements, were performed to determine the height, body weight (BW), hand grip strength (HGS), and arm mass values. After determining descriptive statistics, the Wilcoxon comparison test and Spearman correlation statistical test were performed, and the significance level was taken as p<0.05. In addition, relevant ethical permissions were obtained for the research. Findings: In addition to some differences with reference to the gender variable (Table 2), several significant correlations between hand grip strength and upper extremity (Tables 3-5) were identified. Moreover, a highly significant positive correlation was found between relative arm force (RAF) and hand grip strength (r[subscript RAF-HGS] = 0.707; p<0.001). When their somatotype structures were analyzed, male students were determined to have balanced ectomorph (1.77-1.96- 3.05), while female students had meso ectomorph (0.08-1.09-2.24) and overall (males & females) had meso ectomorph component (0.53-1.32-2.46). Conclusion and Suggestions: It was observed that the height values of the students were below some minimum value criteria for occupations such as police work, while their body mass index (BMI) values were within the normal range. Although the results were close to sedentary health professionals in terms of HGS, they were at a lower level than those of athletes. It is obvious that the students had different somatotype components regarding athletes. Based on this research, the conduct of further qualitative research on field workers is recommended as well as introducing some certain physical competence criteria in the recruitment of paramedic students.

Purpose: This systematic review aimed to identify studies evaluating the impact of high-intensity interval training when delivered in school and sports training. Methods: A systematic search of 10 databases (September 2019) identified 24 eligible studies (including children and/or adolescents 5-18 years and reporting cardiometabolic health and/or health-related fitness outcomes), assessed for quality using the Cochrane Risk of Bias Tool (version 2.0). Outcomes were synthesized using a random-effects meta-analysis, and potential moderators were explored (i.e., study duration, risk of bias, age, and deliverer/instructor). Results: Standardized mean difference for the effects of high-intensity interval training were significant for body mass index g = -0.27 (p < 0.001), cardiorespiratory fitness g = 0.27 (p < 0.001), lower body muscular fitness g = 0.49 (p = 0.005), and upper body muscular fitness g = 0.37 (p = 0.002); but not for blood pressure (p > 0.05). Risk of bias results were variable (low = 8, some concerns = 9, and high = 7). Conclusion: Our findings suggest that embedding high-intensity interval training in schools and sports training can facilitate improvements in some aspects of cardiometabolic health and fitness in children and adolescents.

The aim of this study is to determine the most usable of the three most commonly used tests for male and female athletes, which are applied to determine the agility levels of athletes according to sports branches in terms of their basic motor characteristics. The research group consists of a total of 72 volunteer students, 26 females and 46 males, who were studying at the Coaching Department at Bayburt University School of Physical Education and Sports. In the study, the Sit and Reach test, Takkei brand back and leg dynamometer, 20-meter speed test, T-test which is one of the agility tests, the 505 test and Illinois tests were used. In the analysis of the data obtained in the study, descriptive statistics and normality analysis were performed by SPSS 25.0 program. In order to determine the relationship between motoric properties and agility test values Bivariate-Pearson Correlation test was applied. 0.05 was determined as the level of significance. In the study, a negative correlation was found between women's leg strength and T-test, and flexibility values and the 505 test, while a positive correlation was found between the speed values and the Illinois test. And statistically significant and positive correlations were found between men's leg strength and Illinois test, and speed values and T-test. In addition, a negative relationship was found between Illinois test and flexibility values although it is not significant. The study showed that while agility test is preferred; T-test should be preferred for branches requiring strength, Illinois test should be preferred for branches requiring speed and 505 test for branches requiring flexibility in women. For men, T-test should be preferred in branches that require speed, and Illinois test should be preferred in branches that require flexibility. In addition, it shows that the Illinois test should not be preferred in the branches requiring force.

Posture deformation occurs under the influence of factors that violate the vertical position of the spine. When the load on the spine is redistributed, the position of the body is adjusted by selective training of the muscles of the trunk and changing the position of the pelvis in the frontal plane. Exercises for impaired posture should be aimed primarily at preventing progression and correcting curvature and twisting of the vertebrae. It is important not only the correction of curvature, but also the stabilization of the spine in a corrected position. Saving the achieved results contributes to the formation of a new static-dynamic stereotype of the spine. This is possible by deliberately influencing the upper and lower in relation to the main curvature of the links of the musculoskeletal system and muscle tone-regulating groups involved in posture formation.

This research was conducted to determine whether there are differences between the norm values used in the evaluation of children who train in different sports and physical education lessons according to the chronological age and biological age of the children. The research group consists of a total of 239 male students of 13 (n=116) and 14 (n=123) chronological years, who study in grades 7 and 8. In addition, the biological ages of the students who make up the research group are calculated and divided into 13(N=140) and 14 (n=86) biological age groups. Within the scope of the research, heights, body weights, body mass indexes and body fat percentages of students were determined as anthropometric variables. Hand grip, leg strength, flexibility, horizontal and vertical jump, medicine ball throwing, ball throwing and sprint running skills were measured as motoric performance variables. The differences of variables according to chronological age and biological age were calculated by the Independent-Samples t-test. According to age groups, the arithmetic mean (x) is shown as 10%. While establishing the norm, the ratings accepted as Canadian criteria were used. In our study, significant differences were found between body weights in 13 and 14 age groups according to both chronological age and biological age. While there is a similarity in 13 age group in terms of heights, difference in favor of biological age was calculated in 14 age group. Even if there is no difference in the comparisons made for the bio motor abilities that are the subject of our study, percentage differences were found in comparing norm values in 10% slices according to chronological age and biological age. Thanks to norm values generated according to both chronological and biological age, the physical condition of the children, strengths and weaknesses related to the level of students in physical education classes, according to the separation of the application groups of children directed to the appropriate sport or the athletes and the students about training programs that will be applied to the course content it is envisaged that the results of this research will provide guidance. In this way, it is thought that by dividing the chronological age and biological age in children, a possible loss of motivation will be prevented in both physical education and training and competitions.

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.

The purpose of this study is to examine the relationship between core stability and some performance parameters in 14-16 age group male long distance runners and football players. 15 male long distance runners and 15 male football players with an average whose height measured ranged from 172.400 ± 7.3513 cm participated in the study. Core stability was determined by plank test and performance values were measured by using tests such as; 30 m speed running, pro-agility, long jump and 60 s shuttle pull. Descriptive and paired-sample t tests were used to compare core stability and performance values. When it is analysed according to football and athletics branches, it is seen that there is no significant difference between the branches in terms of height, body weight, BMI (Body Mass Index), plank and shuttle numbers they can pull in 60 seconds (p < 0.05). However, it was found that 30 m speed running time, standing long jump distance and pro-agility test values showed a significant difference in favour of athletics (p < 0.01).

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 article is to explore the concept of resistance training skill literacy and discuss related strategies to enhance learning, improve adherence and help youth realize the holistic benefits of resistance exercise.

The purpose was to evaluate the intra- and inter-session reliability of hip isometric strength assessment using a frame-stabilized dynamometer (FSD) and to compare the results in the hip adduction (ADD) and abduction (ABD) strength assessment using handheld dynamometer (HHD). Twenty participants (24.2 [2.6] years, 69.3 [10.0] kg) underwent testing on an FSD (ADD and ABD short and long-lever, internal [IR] and external rotation [ER] tests) and using an HHD (ADD and ABD long-lever tests). Analysis revealed excellent (ICC[subscript 2.k] > 0.90) relative intra-set and inter-set reliability for two visits and good reliability for test-retest results (ICC[subscript 2.1] 0.79-0.90), regardless of the test. Among the tests, SEM and MDC were the highest for the IR and ER results. In comparison with HHD, long-lever ADD strength was higher and long-lever ABD strength was lower when measured using FSD. Although both measurements have been shown to be highly reliable, the discrepancy between the devices exists.

The purpose of this article is to provide practical applications for eccentric focused RT through the lens of DI that K-12 PE teachers can incorporate within their curriculums. Within the DI framework, differentiated assessments are key to measure readiness and the product of learning. The Brockport Fitness Tests are presented as a strategy to employ differentiated assessments. Eccentric focused RT protocols and exercises are outlined to accommodate varying ability levels. Additionally, an example weekly plan and workout template are presented as useful examples for teachers to utilize to promote effective and motivating strategies.

Objective: To examine the presence of body image concerns, drive for muscularity, and disordered eating behaviors in collegiate student-athletes. Participants: One hundred and one NCAA Division I student-athletes participated in Phase I; 15 of these also participated in Phase II. Methods: This study employed a mixed method, sequential explanatory design. Participants first completed survey measures assessing body image concern, drive for muscularity, and eating behaviors. These results influenced open-ended, semi-structured interviews, which were thematically analyzed. Results: Body image and disordered eating behaviors were of greater concern than drive for muscularity. Student-athletes reported engaging in eating behaviors as opposed to not eating, yet these eating behaviors trended toward disordered behaviors such as obsessive "healthy eating" or orthorexia. Conclusions: This study took a novel methodological approach to examining student-athlete body image and eating behaviors. Results emphasize the need for further support and education for student-athletes around body image and eating behaviors.

This study assessed whether trunk flexor and extensor strength were predictors of time to stability (TTS) and center of pressure (CoP) during hop and hold tasks in children. Seventeen boys (age, 10.1 ± 1.6 years; height, 1.45 ± 0.11 m; mass, 26.7 ± 7.83 kg) undertook isokinetic strength assessments of concentric and eccentric trunk flexors/extensors at 60°/s, and anterior/medial hop tasks. Hierarchical multiple regressions determined whether concentric and eccentric trunk flexor/extensor peak torques predict TTS using a composite score (Comp[subscript X] Comp[subscript Y] Comp[subscript Z]) and CoP[subscript X] and CoP[subscript Y]. Concentric trunk flexors were the strongest predictor for TTS Comp[subscript XY], with concentric flexion and eccentric extension predicting TTS Comp[subscript Y]. All muscle actions were also strong predictors for CoP[subscript Y] during hop tasks. These findings have implications for the assessment of trunk musculature strength and measures of postural control within a young healthy population. The development of trunk musculature strength may aid improvements in dynamic balance tasks in children, with implications for fall and injury risk. To improve trunk musculature strength and the potential to maintain postural control, a combination of concentric and eccentric exercises with other training modalities appears relevant due to the increased relevance to the demands of balance maintenance.

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.

This study aims to analyze the effects of 6-week core training on certain biomotor abilities for footballers in the pubertal period. Accordingly, 30 male footballers who attend football courses regularly participated in the study. Footballers were divided into two groups; 15 of them were assigned to the Core Training Group (CTG) (age: 9.73 years; height: 139 cm; and body weight: 33.66 kg.) while 15 of them were assigned to the Conventional Training Group (CONTG) (age: 10.06 years; height: 139 cm; and body weight: 35.32 kg). While CONTG was applying the traditional training protocol, CTG additionally applied core strength exercises (two days a week for 10-15 min.). The selected biomotor tests were applied to both groups before and after the 6-week application. Between pre- and post-test values in the CTG, a statistically significant difference was found in flamingo balance, core stabilization balance, hand grip strength, 30 sec. abdominal crunch and 30 m sprint tests (p<0.05). In the CONTG, a statistically significant difference was found in 30-second push-up test values between pre- and post-tests (p<0.05). Comparing the pre-tests between groups, a statistically significant difference was found in flamingo balance and vertical jump tests (p<0.05). Also, comparing the post-tests, a statistically significant difference was found in core stabilization balance and vertical jump tests (p<0.05).

In order to monitor training effects and physical developments in elite sports, it may be beneficial to perform anthropometric measurements and physical fitness tests regularly. In this study, the relationship between the anthropometric properties and physical fitness values of elite figure skating athletes were investigated. 21 elite athletes in the 11-16 age group, female (n=12) and male (n=9), participated in the study. Anthropometric measurements were taken in accordance with The International Society for the Advancement of Kinanthropometry (ISAK) protocol. [sigma]6 and [sigma]8 skinfold thickness, body fat ratio (BF%), body mass index (BMI), Manouvrier Index (MI), waist/hip ratio and somatotype components in girls Group II, III and in boys Group II were calculated. Also, balance, flexibility, handgrip strength, vertical jump, agility, medicine ball overhead back throw, speed, and endurance tests were applied to all groups. Descriptive statistical analyzes were made using the IBM SPSS 25.0 statistics program. The relationship between variables was calculated by the Pearson Correlation coefficient. The significance level was taken as p<0.01 and p<0.05. In boys, body weight, body height and arm span, sitting height, BMI, humerus breadth and foot length were observed to be associated with all physical fitness parameters (p<0.01, p<0.05), except balance and agility; Girth measurements were related to handgrip strength, vertical jump, overhead medicine ball backward throw, speed and endurance (p<0.01, p<0.05). Negative relationships of the endomorphic feature with flexibility and endurance were determined (p<0.05). In girls, it was found that body weight, body height, and arm span, sitting height and BMI were related to flexibility, handgrip strength, medicine ball overhead back throw (p<0.01, p<0.05); girth measurements were found to be related to flexibility, handgrip strength, vertical jump, overhead medicine ball back throw (p<0.01, p<0.05); also, significant correlations (p<0.01, p<0.05) were found between the handgrip strength and breadth measurements. Assessment of the relationship between morphological features and motor skills with specific field tests and standardized tests performed at regular intervals in athletes can contribute to the athletes' selection and training planning of the relevant federations and orientating towards their goals.

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.

In this study, the effect of core training on some motor features of university footballers has been examined. 36 footballers both studying at Mugla Sitki Koçman University in Mugla, Turkey and playing in amateur leagues participated in the study. 18 university footballers of Mugla Sitki Koçman University Sports Club who play in Mugla Super Amateur League formed the experimental group (EG) (Age X = 21.4 ±2.12 years, Height X = 174.3 ±6.84 cm and Weight X = 75.9 ± 8,43 kg ). 18 footballers with amateur licences who play in the Faculty of Economics and Administrative Sciences, train regularly and play in the university faculty matches formed the control group (CG) (Age X = 21,6 ±2.56 years, Height X = 176.7 ±7.13 cm and Weight X = 76.3 ±8.43 kg). The required permissions were obtained and the students filled in the "Admission Consent Forms" before the applications. The trainings were done in the football field of Mugla Sitki Koçman University and the measurements were taken on the Faculty of Sports Sciences Physiology Laboratory. The 10-movements core training programme for eight weeks was applied to the EG footballers in addition to their weekly 2-day football training when the footballers in the CG continued their regular trainings. Before the study, the leg strength, back strength, right-left hand griping strength, flexibility, and vertical jump measurement were taken as pre-test values. After the 8-week training, the final measurements of the EG and the CG were taken. The comparison between the Pretest and Posttest was studied statistically with paired sample t test at 0.05 significance level Consequently it was determined the that the 8-week Core Training provided the undergraduate footballers with an improvement of their the leg strength, back strength, right hand griping strength and vertical jump (p<0.05). No improvement in flexibility features was observed.

This study was carried out to determine the effect of lower extremity muscle fatigue on proprioceptive sense in soccer players. 26 male soccer players who play licensed soccer in the amateur soccer teams of the Agri province and who was not injured in the past year (Age 20,03±3,38, weight 65,69±10,66, height 176,61±8,72) participated in the study voluntarily. The lactic acid concentration of the participants at rest and their proprioceptive sense measurements were determined by standardized methods and materials. Then, Wingate test was applied to the participants. The lactic acid concentration and proprioceptive sense measurements were repeated at the end of the test. The analysis of the collected data was carried out through the SPSS 22 program. Shapiro-Wilks test was conducted for normality distribution. Independent-Samples t-test was carried out in the comparison of test and control groups and Paired-Samples t-Test was utilized in the comparison of differences between pretest and posttest means. It was concluded that lower extremity fatigue in soccer players has a negative effect on lower extremity proprioceptive sense (p<0.05).

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.

Handgrip strength is an important determinant of general health. The primary purpose of this study is to examine the handgrip strength levels in adolescents in terms of sports participation. The second purpose is to determine the association between handgrip strength and other strength parameters. Physically active adolescent athletes (n = 31, 14.26 ± 0.68 years), and the age, pubertal stage and gender-matched non-athlete adolescents (n = 31, 14.21 ± 0.66 years) at the age of 13 to 15 participated in the study. Maximum isometric muscle strength for hand, leg, and back were measured with a handheld dynamometer. Handgrip strength was correlated with leg strength and back strength (r=0.675; r=0.698, respectively). Non-athletes had lower strength values compared to the athletes (98.48 ± 38.25 kg vs 82.94 ± 33.70 kg; 91.48 ± 35.23 kg vs 70.35 ± 25.81 kg; 30.53 ± 7.05 kg; 25.97 ± 5.98 kg for leg, back and handgrip strength, respectively). There was a positive correlation between handgrip strength and other strength parameters in adolescents. Therefore, handgrip strength can be used as a general strength indicator in adolescents. Sports participation in adolescents seems to increase strength parameters notably and may affect health correlatively.

Background: Performing regular muscle-strengthening activity has numerous health benefits, including improvements in blood pressure, hemoglobin A1c, and lean body mass. Despite the disproportionate prevalence of lifestyle-related chronic disease in Latinas (diabetes, hypertension, obesity), most do not report meeting the national guidelines for muscle-strengthening activity. Existing physical activity (PA) research in Latinas has focused almost exclusively on aerobic PA. Our study examined Latinas' sociodemographic and psychosocial correlates of meeting muscle-strengthening PA guidelines that can inform future PA interventions. Method: A cross-sectional study of participants (N = 436) enrolled in a randomized controlled trial promoting PA and cancer screening in Latinas was conducted, and t tests examined the associations between sociodemographic and psychosocial factors with self-reported muscle-strengthening activities. Hierarchical regression was conducted in separate blocks guided by the socioecological model (sociodemographic, individual, and interpersonal factors) to examine the independent contribution of each block to the outcome of meeting national guidelines for muscle-strengthening PA. Results: Participants who met the national PA guidelines of [greater than or equal to]2 days/week of muscle-strengthening activities reported significantly higher social support for PA (p < 0.001), greater use of behavioral strategies for PA (p < 0.001), and lower barriers to PA (p < 0.03) than those who did not meet the guidelines. Hierarchical binary logistic regression indicated behavioral strategies for PA was the only significant correlate of meeting the national guidelines for muscle-strengthening PA (odds ratio = 1.39, 95% confidence interval [1.18, 1.65], p < 0.001). Discussion/Conclusion: Results support a hypothesis that instructing Latinas to use behavior change strategies could help them increase muscle-strengthening PA.

Purpose: The purpose of this study was to investigate the effects of tongue-strengthening exercise (TSE) on tongue strength and effortful swallowing pressure in young healthy adults. Method: Thirteen young healthy volunteers (six men, seven women; M[subscript age] = 20.5 ± 0.5 years) performed 8 weeks of isometric TSE 3 days per week. A tongue pressure measurement device was used to measure maximum isometric tongue pressure (MITP) and conduct the TSE, and a tactile sensor system attached to the hard palate was used to measure effortful swallowing pressure. MITP and effortful swallowing pressure were measured at baseline, after 4 and 8 weeks of training, and at 4 and 8 weeks after the last training session to examine the detraining effects. Results: The results indicated that both MITP and effortful swallowing pressure increased significantly from baseline to 8 weeks after training. Although the improved MITP significantly decreased at 4 and 8 weeks after training cessation, no detraining effect was observed for effortful swallowing pressure. Conclusions: TSE is an effective method for increasing tongue pressure in wide tongue-palate contact areas during effortful swallow. The effortful swallowing pressure gained with TSE appears to be maintained for at least eight nontraining weeks.

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.

This study aimed to investigate the effects on the dynamic balance of two different resistance training in male basketball players. 25 male basketball players who were over 18 participated in the study voluntarily. Participants were divided into two groups by using random sampling method as VertiMax strength training group and traditional strength training group (VertiMax, n=13; classic, n=12). Both training programs were administered 3 times a day for 6 weeks. In standing position, the dynamic balance values recorded on the right and left foot for 60 seconds were assessed by using EasyTech Libra Oscillating balance board. The scores used in the assessments were IBP (index of balance precision), recovery time right (return time of the visual helix balance from right side), and recovery time left (return time of the visual helix balance from left side). All tests were performed with visual feedback. Statistical analysis used three-factor mixed ANOVA. At the end of the training period, IBP (index of balance precision), recovery time right (return time of the visual helix balance from right side), recovery time left (return time of the visual helix balance from left side) showed that dynamic balance scores were similar in the VertiMax and classic training groups for right and left feet. VertiMax group in dynamic balance, the changes in IBP and recovery time right scores were found to be better. In both training groups, when the recovery time right values of the right and left feet were compared at the end of the process, it was seen that the rotation time from the right side of the visual helix motion area of the left leg was shorter (p<0.05). The results show that the VertiMax strength training included in the pre-season exercises positively affects participants' balance performance.

The parkour is a physical activity that contains special technique applications and requires a great number of jumps. The purpose of this study was to investigate the effects of 8-week strength training on the jump heights of the traceurs (parkour practitioners). A total of 12 traceurs, including 6 individuals as the control group and 6 individuals as the strength group, were included in the study. The control group was provided with parkour training sessions twice a week, and the other group provided with both strength and parkour training sessions twice a week. Each participant's vertical jumps were recorded with the high-speed camera in the validated My Jump 2 application. The mean age of the traceurs control group was 19±.89 years, 173.67±4.63 cm, body mass 66.5±5.32 kg; experimental group was 19.5±1.05 years, 175.83±8.86 cm, and body mass 67.67±7.20 kg. Also according to the results, it can be said that a significant increase was observed in countermovement jump (CMJ) vertical jump heights (p=0.028) of the study group at the end of the 8-week strength trainings compared to the control group and that the strength training provided a positive contribution to vertical jump heights. On the other hand, there was no significant difference (p=0.075) in the control group. At the same time, the CMJ height values of the participants who performed strength training increased 4.97±0.09%. Learning of the vertical jump heights, which is an important parameter for successful performance in traceurs, can enable the coaches and athletes to prepare a better training program.

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 effects of core strength training on balance, explosive force and agility. 28 athletes volunteered in the study. The athletes were separated into two groups: the experimental group (n=15) with the average of age and weight of 19.5 ± 1.2 years and 64 ± 8.9 kg, respectively and the control group (n=13) with average age and weight of 19.4 ± 1.5 years and 67.4 ± 10.3 kg respectively. During the intervention, both groups continued their normal training sessions for 8 weeks. The experimental group performed thirteen core movements 3 times a week for 8 weeks, while control group did not. The experimental group performed each movement with 20 repetitions of 3 sets and a 1 minute rest between sets. Pre and post-intervention, standing long jump, Illinois and double right/left foot balance tests were used to determine the explosive force, agility and balance performance, respectively. Wilcoxon Signed Ranks test was used for the analysis of the difference between pre-test and post-test groups and Mann Whitney U test was used for the comparison of the two groups. In order to make statistical analysis of the study, the significance level was accepted as p <0.05. After the 8 week intervention, both groups' participants showed significant improvement in the explosive force and agility performance; whereas no significant difference was found in the double right/left foot balance test results. When the difference between the groups was examined, the post test results showed a significant difference in long jump and agility tests. The post test results of the experimental group were found to be higher than the control group. The 8-week core strength training intervention showed no effect on athletes' balance but a positive effect on long jump and agility were observed.

The purpose of this research is to examine the maximal isokinetic leg strengths of male athletes who work in different branches of taekwondo and boxing, both bilateral and unilateral, as right and left legs. Totally 32 athletes, including taekwondo athletes (n = 16) and boxer (n = 16), participated in the study. In the 2016-2017 season, the average age of these athletes is x-bar = 21.5. Biodex isokinetic system 4-Pro analyzing device was used in the study and 180 ° / s flexion and extension right and left leg maximal strength measurements were made from this measurement. Before the measurements, the athletes performed the exercise program including 15 minutes of warm-up movements and the maximal strength measurement was applied to each athlete 2 times. Their best performances were recorded and evaluated. When the findings of the study were examined, the right extension, right flexion, left extension, and left extension isokinetic strengths of the taekwondo athletes were found to be higher than the boxers. There was a very high and meaningful correlation found between right flexion and left flexion isokinetic strengths in the boxers between right extension and left extension isokinetic strengths. In Taekwondo athletes, there was a weak and meaningless correlation between right flexion and left flexion kinetic strengths and a positive correlation was found between right extension and left extension isokinetic strengths. Consequently, it was seen that isokinetic maximal leg strength of taekwondo athletes was higher than boxers. It is believed that this is due to the more intensive use of lower extremity muscles in taekwondo. Besides, in this research, there was a very high correlation between the right and left extension of the boxers and isokinetic leg strengths at the flexion while there was a weak meaningless correlation between the right flexion and left flexion isokinetic strengths of the taekwondo athletes, and a positive correlation was found between the right extension and the left extension isokinetic strengths. Thus, in the right and left isokinetic leg strength values of the boxers there was closeness, and in the right and left isokinetic strength values of them it can be said there was not so much closeness exists.

The paper is devoted to the issues of improving the methods of physical training. Currently, the method of teaching and training schoolchildren is developed mainly with a focus on a child's age, which does not always correspond to his or her biological maturity. These reasons together with the growing phenomenon of child acceleration reinforce the relevance of the research topic. The purpose of the study is to evaluate the impact of speed-strength exercises on the physical development and speed-strength qualities of schoolchildren aged 11-12. The authors used the measurements of anthropometric and physiometric indicators, as well as the tests that determine the level of development of speed and speed-strength qualities. The results of the research show that the physical indicators of the test group tend to increase, and during the school year, many indicators significantly change.

The purpose of this study is to investigate the effect of regular CrossFit training on some force and jump parameters. 32 healthy wrestling men participated in the study, 16 experimental and 16 control groups. For the experimental group, CrossFit training, known as Cindy, was practiced three times a week for 8 weeks. The training consisted of 5 bars, 10 push-ups and 15 squats for 20 minutes. The control group continued the classical wrestling practice. Myotest accelerometric system was used for measurements of participants' values. For the analysis of the data, repeated measure ANOVA was used. According to the results, as a result of CrossFit training, athletes' squat jump heights increased (Wilks' Lambda = 0.541, F (1,30) = 25, p = 0.00). The mean post-training leap values (33.778 ± 5.48) were higher than the pre-training leap values (32.169 ± 4.95) (p <0.05). It can be concluded that Cindy CrossFit studies improve jumping and strength ability.

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.

The aim of this research was to investigate the effect of vibration applications on muscle strength and balance. As the subjects to the research, nineteen male sport science students (age: 21.45±2.16 years, height: 177.55±7.24 cm, body mass: 71.62±11.02 kg) voluntarily participated in the study. The students were exposed to vibration in squat exercise position before they were exposed to vibration at 25Hz, 50Hz frequency and control (no-vibration) on three different application days. Before and after the vibration exposure, jump tests and balance tests were administered right after the 5th, 10th and 15th min in the wake of the vibration. A statistically significant difference was found in active and squat jump heights administered following the 25Hz and 50 Hz frequency applications (p[less than or equal to]0.05). No significant differences were found in the jump heights in control group (p>0.05). While there was no significant difference found in balance tests performed after 25Hz and 50Hz vibration applications (p>0.05), a significant difference was found after the control application (p[less than or equal to]0.05). As a result, there was an increase in jump heights following the acute vibration application however, no change was seen in balance scores. Practicing acute vibration applications can be recommended to increase jump height especially before the competitions and applications.

The purpose of this research is to compare the elbow isokinetic strength applied at different angular velocities on the dominant and non-dominant side in elite male volleyball players. Fifteen elite volleyball players participated in the research. Isokinetic elbow flexion and extension strength were separately obtained on concentric/concentric dominant and non-dominant side as 5 repetitions at 60 degrees .s[superscript -1] angular velocity, 10 repetitions at 180 degrees .s[superscript -1] and 15 repetitions at 300 degrees .s[superscript -1]. In the research, the peak torque (PT), peak torque/body weight (PT/BW), flexion/extension ratio (B/T), angle of PT, work and power parameters were compared between the dominant and non-dominant elbows. No significant difference was found between the dominant and non-dominant side in the elbow isokinetic strength parameters of the subjects at three different velocities. A significant difference was found at three different velocities only in the angle of PT flexion (p < 0.05). It is thought that this difference may result from the muscle shortening that may occur on muscle length (longitudinal effect) as a result of the more concentric contraction of the muscle on the dominant side compared to the non-dominant muscle. Consequently, there is not any isokinetic strength difference between the dominant and non-dominant elbow in elite male volleyball players. Isokinetic elbow test can provide important information regarding the potential risk factors for elbow injuries. For this reason, it is recommended to include this test in the functional screening of volleyball players.

The purpose of this research is: (a) to compare the dominant and non-dominant leg isokinetic strength and balance, (b) to compare the balance applied on the same side to different directions and isokinetic strength applied to the same side at different angular velocities and (c) to examine the relationship between the balance and isokinetic strength applied at different angular velocities in female volleyball players. Eleven senior female volleyball players voluntarily participated in the research. Isokinetic knee flexion and extension strength were separately obtained on concentric/concentric dominant and non-dominant leg as 5 repetitions at 60 degrees .s [superscript -1] angular velocity, 10 repetitions at 180 degrees .s [superscript -1] and 15 repetitions at 300 degrees .s [superscript -1]. The balance test was performed for both sides in anterior (ANT), posterolateral (PL) and posteromedial (PM) directions. In female volleyball players, there is no significant difference between the dominant and non-dominant leg in terms of isokinetic strength and balance. A significant difference was detected between the balance applied in different directions on the same side and isokinetic force applied at different angular velocities. However, there is not any significant relationship between isokinetic strength and balance in female volleyball players. As a result, there is no isokinetic strength and balance asymmetry in volleyball and there is no relationship between them. This may be an indication of the need for both legs in volleyball.

Maximal strength, muscular endurance, maximal aerobic power, and anaerobic capabilities, power are needed to have victory for wrestlers in a wrestling competition.The aim of the study is to investigate the effect of acute muscular fatigue on static and dynamic balance performances in elite wrestlers. Ten elite male wrestlers (25 ± 2.3 years, 181 ± 6.5 cm, 84 ± 4.2 kg) participated in the study voluntarily. Participants were undertaken dynamic and static balance test before fatigue exercise (in Cybex) and immediately after fatigue exercise, they were undertaken dynamic and static balance test again. SPSS packet program was used to evaluate the data. There were no statistically significant differences in static and dynamic balance before and after fatigue. The results show that wrestlers' balance is not affected by muscular fatigue, so there is no need for balance exercise after fatigue at least according to this study.

The aim of this study was to investigate the effect of CrossFit and resistance training on maximal strength, isometric strength and strength continuity in recreational student athletes. 28 healthy male volunteer students who were doing sport for recreational purposes participated in the study. After the participants were randomly divided into two groups, strength tests were performed and body composition measurements were taken before and after the 16-week training period. Bench press and squat were applied to determine maximal force; leg and handgrip strength were applied to determine isometric force; pull-up and push-up tests were applied to determine the continuity of strength. Body composition measurements were performed with electronic scales. Statistical analyses were performed with SPSS 21.0 program. Significance level was accepted as p <0.05. The CrossFit training program included consecutive 5 pull-ups, 10 push-ups and 15 squat exercises for 20 minutes (CrossFit-Cindy). Resistance training program consisted of 3 sets of bench press, lat pull down, leg press, biceps curl and triceps extension exercises with 3 minute intervals using 70% of the weights the participants could perform with pre-determined maximum 1 repetition. The results of the study showed that body fat percentages of both groups decreased significantly, performance variables increased significantly and body weight did not change significantly. In addition, the increase in push-up exercise was higher in the CrossFit group than in the resistance group. Thus, this study shows that although CrossFit training is short-termed, it can be used as an alternative to classical resistance training.

In this study, it was aimed to investigate whether basic swimming training has effects on height, body weight, right and left hand grip strength, right and left hand lengths, shoulder width, chest circumference, standing long jump characteristics. The study is important in terms of making individuals in the growth period and investigating the physical development of major technical studies from force studies. It is known that regular sport has also developed physical features along with many other features. However, there is not a complete consensus about the sport, its violence, its frequency and duration. The study using the experimental research method included 114 individuals with a mean age of 11.03 ± 1.23 years. The study group, consisting of 58 subjects, received regular swimming lessons twice a week for two hours at a time over a period of 7 months. The sedentary control group included 56 subjects who received no sports instruction apart from their standard physical education classes. Prior to the start of the study, measurements were taken for height, body mass, right and left hand grip strength, right and left hand length, shoulder width, chest circumference, and standing long jump for both groups. The same measurements were taken again 7 months later, at the conclusion of the study. The differences between the initial and final measurements of both the study group and the control group were statistically compared within the group and between the groups. In this comparison, the General Linear Model method was used in the SPSS 21 Package program. As a result, it was found that the increase in height, body weight, right hand grip strength, right and left hand lengths, chest circumference and standing long jump mean values of swimming training subjects were found to be different at p <0.001 in the control group in seven months period. It was also found that the increase in the mean value of left hand grip strength in both groups was significantly different in favor of swimming training subjects (p <0.005). The increase in shoulder width mean values of the study group and the control group did not differ between the groups (p> 0,005).

The purpose of this study was to investigation of the effect of six weeks electrostimulation training on physical changes in the sedentary men and women. Electro muscle stimulation (EMS), which is applied since the discovery of contraction under the influence of electrical currents, on the purpose of rehabilitation and treatment purposes, has attracted the attention of coaches, athletes and sports scientists as a popular training method over time. In the present research, 6 weeks, 3 days a week and for 25 minutes in a day of EMS machine training program was applied to the sedentary women[subscript n = 12] and sedentary men[subscript n = 12]. In order to determine effect of EMS machine training on the physical changes which are body mass, % body fat, fat mass, body mass index, total body water, fat free mass, muscle mass, Tanita (SC-300) Body Composition Analyzer was used as a pre-test and post-test. The results of the Tanita body measurements were analyzed by using SPSS computer program, the standard deviations were calculated, and pre- and post-training statistical paired samples T Test analysis were made. According to SPSS analysis results, there are statistically significant increases in the % body fat, fat mass, soft muscle tissues, extracellular and intracellular liquid weights and cell mass weights (p<0.05). There are increases in other results which is, body mass, BMI, muscle mass, metabolic ages, obesity levels, internal fat, bone mineral weights and skeletal muscle mass, but not statistically significant (p>0.05).
