The aim of this study was to determine the relation between some motoric and physiological characteristics of 13-15-year-old female volleyball players regarding their positions on the field. A total of 120 volleyball players have participated voluntarily. 30 of the participants whose mean age value was 14±0,76 were setters; 30 of them were liberoes with mean age value of 13,8±0,45; 30 of them were middle blockers with the mean age value of 14±0,79; 30 of them were hitters with mean age value of 13.52±0,68. The age, height, body weight, right-left hand gripping strength, vertical jump, throwing medicine ball, standing long jump, 30-second speed and body fat percentage measurements of the volleyball players have been performed. In evaluating the data, the One Way ANOVA has been used. No statistically significant differences have been determined between the age, weight right hand gripping strength and body fat percentage measurement results concerning the positions of the volleyball players, who participated in the study (p>0.05). On the other hand, it has been identified that there is a difference between the height, left hand gripping strength, throwing medicine ball, standing long jump, and speed values in terms of their positions (p<0.05). The results of the study could be beneficial to evaluate the motoric and physiological characteristics of the volleyball players regarding their positions in establishing teams and in preparing training programs.

Body composition and the skill of jumping are very important for high physical performance in volleyball. The purpose of this study is to analyze the relationship between body composition and jumping performance in female volleyball players aged 14-17. 74 female volleyball players volunteered to participate in the study. The height, body weight, body mass index, body fat percentage, body muscle mass and trunk fat percentage measurements were taken and the vertical jump and standing long jump tests were applied. The data were evaluated with the SPSS 16 statistical software program, the Pearson Correlation test was done for the statistical analysis and the significance level was determined as p< 0.05. The athletes’ vertical jump and standing long jump values were found statistically to have a negative relationship with height, body fat percentage, body muscle mass and body fat percentage, whereas a positive relationship was found between vertical jump and standing long jump values and body weight (p< 0.05). As a result, it was determined that body composition in volleyball players affects jumping performance.

The main aim of this study was to compare anthropometric and physical fitness indicators of boys of the same chronical age but with different fat percentages. Subjects were Hungarian boys aged 9–13 years (N = 6919). Anthropometry was measured according the guidelines of the International Biological Program. Relative body fat was estimated by Drinkwater–Ross’s method (1980); Conrad’s growth type of physique was also estimated (1963). Physical fitness was tested with 30 m dash (s), standing long jump (cm), fistball throw (m), and 1200 m run (s). Subjects of each cohort were grouped into seven subgroups with fat percentage ranges of 4%. Differences between subgroups were tested by one-way ANOVA. In the case of a significant F-test, Tukey’s post-hoc tests were used. The level of effective random error was set at 5% in all significance tests (p < 0.05). Except for the three groups with low fat percentages, values of body weight, stature, body mass index, and plastic and metric indexes were significantly higher; results of 30 m, 1200 m running, and standing long jump were worse in all groups with higher fat percentages. An interesting finding of the current study is that body fat percentage also influenced the physical fitness of non-overweight and obese children as well when using merely the 4% ranges in grouping by fatness. The lower the fat the better the physical fitness was in this sample of pre- and peripubertal boys.

The purpose of the study is to compare the physical, motor and physiological features of students in the age group of 12-14 years old who regularly practice in athletics and wrestling sports with non-sports students, and explore its impacts on the sports students' level of branching. The research group was selected among Keçiören Mecidiye Secondary School and Alaeddin Ozdenören Imam Hatip Secondary School students in Ankara. The research group consisted of 47 students; 15 students in the age group of 12-14 years old who are engaged in regular athletics training, 17 students in the same age group who are engaged in regular wrestling training and 15 volunteers in the same age group who do not do sports. Measurements included age, height, body weight, Agility (T-test), hand grip strength, standing jump, vertical jump, body fat percentage, flamingo balance, flexibility, 1 min shuttle, BMI, 30 m speed run, 1000 m run-walk tests. The analysis of the data was evaluated according to the results of the Levene test for homogeneity. If the result was homogeneous, ANOVA method, otherwise Kruskal Wallis comparison test was used. In variables whose averages differed as result of multiple comparisons, the TUKEY test was used to find which groups these differences stemmed from. The results of agility, right and left hand grip strength, flexibility, 1 min shuttle, Body Mass Index (BMI), 30 m speed, 1000 m run-walk tests were statistically significant. However, the results for height, weight, age, long jump, flamingo balance, body fat percentage, vertical jump tests were not statistically significant. When we look at the results, it is found that the best results for 1000 m run-walk, 30 m speed run, agility (T-test), height, long jump, vertical jump were recorded in the athletics group. It has been observed that the wrestler group has better results in body weight, body fat percentage, grasp strength, flamingo balance, 1 minute shuttle and flexibility parameters. The values of the control group were found to be lower than those who were engaged in athletics and wrestling as they did not exercise regularly. When the differences between the groups are evaluated, it can be said that there is a tendency towards branching in a branch in the age group of 12-14 years old.

The primary aim of this study was to determine the association between body composition and performance outcomes in youth soccer players. Twenty-five competitive male youth soccer players (age = 13.7 ± 0.8 years, height = 167.4 ± 9.7 cm, weight = 57.6 ± 12.1 kg) volunteered to participate in this study. Height and weight were used to calculate body mass index (BMI). Body fat percentage (BF%) and fat-free mass (FFM) were determined with dual-energy X-ray absorptiometry. Each athlete performed the Pacer test, vertical jump, and t-test drill. Participants were predominantly normal weight (20.4 ± 2.7 kg·m−2). The body composition results were 20.3 ± 4.9% for BF% and 46.5 ± 8.7 kg for FFM. The results of the performance tests indicated a mean ± standard deviation (SD) of 1418 ± 332 m for Pacer, 57.2 ± 7.4 cm for vertical jump, 11.6 ± 0.7 s for t-test. Body mass index was not associated with any performance measure (r = 0.02 to −0.21, all p > 0.05). Body fat percentage was associated with the Pacer, vertical jump, and t-test (r = −0.62, −0.57, 0.61, respectively; all p < 0.01) and remained after accounting for BMI. Fat-free mass was only significantly related to t-test (r = −0.43, p < 0.01). However, after controlling for BMI, FFM was related to all three performance tests. Body fat percentage and FFM are associated with performance in youth soccer players, with stronger relationships reported in the former metric. The findings highlight the need for accurate body composition measurements as part of an assessment battery in young athletes.

Abstract The number of studies related to soccer has been growing exponentially in the last years because the modality is considered the most popular in the world. It is known that the development of some specific physical capacities, even in young individuals, is essential to high-level performance and these capacities might be related to anthropometrics variables. The purpose of this study was to verify the relationship between body composition and physical capacities in young soccer players. Study participants were athletes from junior categories (under-12 and under-13) belonging to the Soccer Association of Chapecó, Brazil.. Athletes were submitted to agility, (Illinois), vertical jump (Sargent Jump), aerobic condition (TCAR), flexibility and sit-and-reach (Wells Bench) tests, as well as anthropometric assessment. All procedures were performed at UNOESC campus, Chapecó. Statistical analysis consisted of the Spearman’s Rô test, measuring the correlation among variables, additionally, significance level of p<0.05 was adopted. Results showed significantly correlation in agility (p=0.000; ρ=0.530) and vertical jump tests (p=0.003; ρ=-0.437) with body fat percentage. It was concluded that there is relationship between body fat percentage and agility and explosive power of lower limbs.

Prolonged physical inactivity in young adults may lead to deficiencies in musculoskeletal fitness, and thus a need exists to develop physical activity and exercise programmes that are effective of increasing musculoskeletal fitness. The aim of this study, therefore, was to investigate the effects of small-sided team handball training on lower limb muscle strength, postural balance and body composition in young adults. Twenty-six men and twenty-eight women were stratified for peak oxygen uptake (VO2peak) and body fat percentage and randomly allocated to either 12 wks of small-sided recreational team handball training (THG: 14 men and 14 women, age 24.1±2.6 yrs (mean±SD), VO2peak 39.8±5.9 ml/kg/min and body fat percentage 32.7±8.7%) or serving as non-exercising controls (CON: 12 men and 14 women, age 24.8±3.1 yrs, VO2peak 39.7±5.0 ml/kg/min, body fat percentage 31.7±9.7%). THG trained on average 1.8 times/week for 12 wks. At 0 and 12 wks, lower limb muscle strength, rate of force development (RFD), vertical jump height and power, postural balance, body composition and muscle biopsies were assessed. No training effects were observed for maximal isokinetic or isometric knee extensor strength, maximal vertical jump height or take-off power, fibre type distribution or capillarization. Late phase (RFD) increased (+7.4%, p<0.05) and postural sway excursion length was improved after training (-9%, p<0.05) in THG with no difference from CON (p>0.05). Further, THG demonstrated a decrease in body fat percentage (-3.7%) accompanied by increases in whole-body fat free mass (FFM) (+2.2%), leg FFM (+2.5%), total bone mineral content (BMC) (+1.1%), leg BMC (+1.2%), total hip bone mineral density (+1.6%) and hip T-score (+50%) which differed from CON (all p<0.05). In conclusion, recreational small-sided team handball training appears to effectively improve rapid force capacity, postural balance, lean and fat body mass and bone health in previously untrained young adults. The study was registered at ClinicalTrials.gov (NCT04247724). ClinicalTrials.gov ID number: NCT04247724
