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.

IntroductionCadets participating in Reserve Officers’ Training Corp (ROTC) at US universities undergo both Army Physical Fitness Test (APFT) and Occupational Physical Assessment Test (OPAT) evaluations prior to commissioning. The current study examined the relationship between ROTC physical training (PT) attendance and performance in the APFT and OPAT, and characterised physical activity of cadets outside of PT.MethodsTwenty-six cadets’ (21 males; age=20.81±2.48 years; height=171.16±8.62 cm; body mass=75.49±13.17 kg; body mass index=25.68±3.37 kg/m2) PT attendance, and diagnostic (week 1) and record (week 13) OPAT and APFT scores were documented. Paired samples t-tests evaluated differences in APFT and OPAT scores between the diagnostic and record tests. Pearson correlations were utilised to determine if a relationship existed between PT attendance and test performance. Participating cadets also completed monthly self-reported physical activity questionnaire (September, October, November); findings were reported using descriptive statistics.ResultsCadets attended 87% of PT sessions between OPAT administrations and 85% between APFT administrations. Cadets significantly improved the following test components: standing long jump (p=0.034), seated power throw (p=0.029), shuttle run (p=0.005), sit-ups (p=0.003) and 2-mile run (p=0.045). A significant, positive correlation was found between PT attendance and APFT sit-ups improvements (r=0.473, p=0.015). Cadets’ frequently reported additional physical activity days per week (range: 2.8–3.1 aerobic, 3.2–3.8 strength/power, 2.9–3.2 core strength/endurance).ConclusionsRegular participation in a single semester of ROTC PT was found to significantly increase cadets’ scores in some, but not all, components of the APFT and OPAT. Self-reported physical activity results indicate that cadets regularly train outside of organised PT.

Tennis is a sports branch with a lot of coordinated properties. The physical, physiological and motoric properties of the athlete are at optimum level, which influences the stroke performance positively. The aim of this study is to investigate the relationship between biomotoric properties and Hewitt test performance in 13-15 years old tennis players. 10 healthy female tennis players (age: 14.00±1.05 years, height: 158.60±3.69 cm, weight: 53.57±5.22 kg, experience: 3.40±1.58 years) who played in Pamukkale University tennis club participated in this study voluntarily. In anthropometric measurements height, body weight, leg lengths and dominant hand were recorded. Left and right hand grip, countermovement and squat jumps test, flexibility, standing long jump, static and dynamic balance, star test, Wall Catch coordination test and Hewitt performance test were applied to the tennis players. In the statistical analysis of the data, descriptive analyzes of all test performance characteristics of the tennis players were calculated as mean and standard deviation. The relationships between biomotoric properties and Hewitt test performance were evaluated using Pearson Product Moment Correlation analysis. The statistical significance was set at p<0.05. Statistically significant correlation was found between Hewitt test (groundstroke performance) and Wall Catch coordination test (r= 0.865; p<0.01). There was no significant correlation between Hewitt test and leg lengths, dominant hand, left-right foot dynamic balance, standing long jump, flexibility, jump performance, left and right hand grip and star tests (p>0.05). As a result, the use of tests with similar movements special to tennis in evaluating the athlete's performance can accurately reflect the athlete's test values.

Understanding the mechanisms associated with engaging in physical activity (PA) is crucial for its promotion. The aim was to analyze the relationship between motor competence (MC) and PA and the role of physical fitness (PF). Participants were N = 1,064 children of both sexes (n = 530 girls) and 7.87 ± 1.17 years of age. MC was assessed with KörperkoordinationTest für Kinder. PF was assessed with 50-yard dash, 1-mile run/walk, and standing long jump. PA was assessed with a questionnaire. Mediation and moderation were determined according to Baron and Kenny using Sobel test for indirect effect and using PROCESS (version 3.4). Mediation results showed perfect mediation in girls but not in boys and not when all participants were included in the analysis. The linear moderation was significant for all participants and for boys and girls apart. However, the results of conditional effects of MC at the 16th, 50th, and 84th percentile of the PF, which became significant at the 50th percentile for all participants and for boys, were not significant in girls. In conclusion, perfect mediation seems to exist in girls but not in boys. In boys, the relationship between MC and PA seems conditioned by the PF levels.

Sport climbing is now seen as part of the climbing population fi tness interesting resource. Th is study clarifi es the relationship between selected conditioning tests, anamnetic data and performance in sport climbing in the climbing trips OS or RP and each points to a relationship between these ways of ascent climbing routes. Study describes the relation between the diff erent standardized tests selected from Eurofi t test set (standing long jump, full forward trunk bend, pull-up hold, manual dynamometry, „fl amingo“ exercise), anthropometric data (body height, body weight, body fat ratio in %) and anamnestic data (length of climbing experience, climbing performance in terms Red Point RP, and On sight OS). Th e dependency measure is expressed by a linear regression with two dependent variables. Th e dependent variables express climbing performance in terms of RP and OS. Th e signifi cant indicators for dependent variable RP in this given regressive model are length of climbing experience, pull-up hold, manual dynamometry and body weight; for the dependent variable OS, these are length of climbing experience, pull-up hold and manual dynamometry. Aft er the application of a linear regression analysis with two dependent variables, the dependency measure between the RP and OS performance was formulated as a partial correlation rp = 0,745.

In elite adolescence ice hockey players, overall skating performance is an essential performance factor and should be measured adequately, whereas the relationship between on-ice and off-ice performance is not well known. Consequently, the aim of the study was to analyze (1) the differences in on-ice and off-ice performance in elite adolescent ice hockey players, and (2) the relationship between on-ice and off-ice performance in general separated into different age groups. Thirteen under-15, 18 under-17, and 19 under-20 elite male ice hockey players performed the specific overall skating performance test for ice hockey players (SOSPT). Additional tests included 30 m on-ice skating, off-ice skating and off-ice sprinting tests, the countermovement jump test (CMJ), the standing long jump test, the single-leg lateral jump test, and the single-leg lateral skating simulation jump test (Skate SIM). Significant differences (employing one-way ANOVA with a Bonferroni post-hoc test) between under-15, under-17, and under-20 players were found in body mass, height, leg length, CMJ height, standing long jump distance, single-leg lateral jumps from the left and right legs, Skate SIM time, off-ice sprinting time (0–6 m and 0–30 m), off-ice inline skating time (0–30 m), on-ice skating time (0–6 m and 0–30 m), and SOSPT time. Pearson Product-Moment correlation analysis revealed stronger correlations between SOSPT time and on-ice skating, off-ice skating, and off-ice sprinting and jump tests in the under-15 players compared to the under-17 and under-20 players. As expected with increasing age, elite male ice hockey players performed better in on-ice and off-ice performance tests. The stronger relationship between SOSPT performance and on-ice and off-ice performance in the younger compared to the older players revealed that general physical performance determined specific overall skating performance more often in youth players, whereas in junior und young adult players, an optimal skating technique is more important. These results should be considered in the selection process for young ice hockey players.
