The Relationship

Abstract The goal of this study was to examine the relationship between kinematics, motor abilities, anthropometric characteristics, and the initial (10 m) and secondary (30 m) acceleration phases of the 100 m sprint among athletes of different sprinting performances. Eleven competitive male sprinters (10.96 s ± 0.36 for 100 with 10.50 s fastest time) and 11 active students (12.20 s ± 0.39 for 100 m with 11.80 s fastest time) volunteered to participate in this study. Sprinting performance (10 m, 30 m, and 100 m from the block start), strength (back squat, back extension), and jumping ability (standing long jump, standing five-jumps, and standing ten-jumps) were tested. An independent t-test for establishing differences between two groups of athletes was used. The Spearman ranking correlation coefficient was computed to verify the association between variables. Additionally, the Ward method of hierarchical cluster analysis was applied. The recorded times of the 10 and 30 m indicated that the strongest correlations were found between a 1- repetition maximum back squat, a standing long jump, standing five jumps, standing ten jumps (r = 0.66, r = 0.72, r = 0.66, and r = 0.72), and speed in the 10 m sprint in competitive athletes. A strong correlation was also found between a 1-repetition maximum back squat and a standing long jump, standing five jumps, and standing ten jumps (r = 0.88, r = 0.87 and r = 0.85), but again only for sprinters. The most important factor for differences in maximum speed development during both the initial and secondary acceleration phase among the two sub-groups was the stride frequency (p<0.01).

The aim of this study was to investigate the change of direction (COD) ability and deficits of elite rugby union players, discriminating between position (backs and forwards), and between “faster and slower players”, in multiple COD tasks. Twenty-four male rugby union players from the Brazilian senior National team completed the following assessments: Squat and countermovement jumps; drop jump; standing long jump, horizontal triple jumps; 40-m linear sprint; Pro-agility, L-Drill, and Zig-zag COD tests; and squat 1-repetition maximum. The differences between backs and forwards and between faster and slower performers were examined using magnitude-based inferences. Backs were faster (in both linear and COD speed tests) and jumped higher than forwards. Moreover, they generated an inferior sprint momentum. No differences were found in COD deficit between playing positions. However, when dividing the sample by median split, faster players outperformed their slower counterparts in all power–speed variables and presented higher COD deficits. These results suggest that separating rugby players by playing position might not discriminate players with different COD skills and that the median split analysis is more sensitive to identifying these differences. Furthermore, the present data indicate that faster rugby players are less efficient at changing direction and tolerating higher approach velocities in COD maneuvers.

The main motivation for the research is a verification of applicability of the fitness test as a predictor for specific alpine skiing performance of the Czech national team of U14 and U16 categories. We want to verify if the results from the fitness test correspond with points for the performance in alpine skiing disciplines (slalom, giant slalom, super giant slalom). In total, 42 men and women (U14 and U16 categories), members of the Czech national team, participated in the research. Participants were grouped by gender (women n=21, age 14.23 (± 1.04), men n = 21, age 14.19 (± 1.07)). Fitness test consisted of six individual tests and was used as a tool to examine the level of motor abilities (jumping over the Swedish bench, shuttle run 4 × 10m, standing long jump, hurdles agility run - boomerang test, twist test, 20m shuttle run - beep test). Points for the performance in alpine skiing show the best result from a single competition transferred to the points. In our research we were looking for relationship between the points from three different disciplines (slalom, giant slalom, super giant slalom) and the results from the fitness test. In the men category we found high correlation (at the significance level of p ˂ 0.05) between super giant slalom and standing long jump (r = -0.73; r² = 0.53), between super giant slalom and boomerang test (r = 0.62, r² = 0.38) and between super giant slalom and shuttle run 4 × 10m (r = 0.61, r² = 0.37). Small correlation was found between slalom and box jump test (r = -0.31, r² = 0.1), between slalom and twist test (r = -0.33, r² = 0.11) and between super giant slalom and twist test (r = -0.34, r² = 0.12). In women category we did not found high correlation (at the sig-nificance level of p ˂ 0.05). Small correlation was found between slalom and box jump (r = -0.31, r² = 0.1), between giant slalom and twist test (r = 0.01, r² = 0.0001), between super giant slalom and standing long jump (r = -0.03, r² = 0.0009) and between slalom and shuttle run 4 × 10m (r = -0.05, r² = 0.0025). Twist test had very small correlation in both men and women categories. We can say that it is not relevant for prediction of alpine skiing per-formance. Based on different significance of correlations between men and women (super giant slalom and standing long jump; slalom/super giant slalom and shuttle run 4 × 10m) it might be necessary to adjust fitness testing as a predictor of alpine skiing performance according to a gender.

The aim of this research is to confirm differences in the anthropometric characteristics and motor abilities of schoolchildren aged 9 and 10 compared by sex and age. The sample comprised 341 schoolchildren, divided into two subgroups of third (172) and fourth (169) graders. The research is of a transversal character and includes the measurement of anthropometric characteristics and motor abilities by applying the Eurofit fitness testing battery. The results show a significant difference based on sex in terms of body mass (t = 2.148), and as for motor abilities, there is a difference in the Shuttle run test (t = -3.709). A statistically significant difference considering the age of the tested population was observed in height (t = -10.327) and body mass (Z = -5,991), while in terms of motor abilities there was a statistically significant difference in the values of all the tests: Hand tapping (t = 4.735), the Standing long jump (Z = -3,575), Shuttle run (t = 12,248), the Flexed arm hang (Z = -2,167), Sit and reach (Z = -2,406), Sit-ups in 30 seconds (t = -9069). The research shows a higher statistically significant difference observed in body composition, but also in the motor area of the studied group in terms of age, and in relation to the statistically significant difference that was revealed by gender.

The Relationship

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.

The aim of this study is to determine there is a statistically significant difference in motor ability indicators in children of early school age before and after the defined experimental process. The total number of subjects is 40 and the subjects was divided into two subsamples: a subsample of boys (n = 20) with an average age of 6.20 ± 0.34 years and a subsample of a girls (n = 20) with an average age of 6.16 ± 0.62 years. All subjects were participants in the program of the sports school of the children fitness centre Smart Gym from Podgorica. Subsamples were subjected to an experimental process lasting 8 weeks. Immediately before and after the experimental process, motor abilities were measured using the following 10 tests: 5m sprint, 10m sprint, standing long jump, polygon backwards, bent arm hang, sit and reach, climbing and descending, stork balance stand test, sit ups, and throw and catch test. The results of the study show that the experimental process was successful in improving the polygon backwards, forward deep bend and throw and catch test in boys and stork balance stand test, sit ups and throw and catch test in girls. Such a program could improve the working methodology in all sport schools throughout Montenegro.

The Relationship

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.
