Purpose: Plyometric exercises, in the form of jumping, are extreme physical activities. The aim of the study was to determine how symmetrical-single versus asymmetrical-continued plyometric exercises differ between men and women and affect speed abilities. Methods: Twenty-two healthy females and forty-four males from different sports practices participated in the investigation. The countermovement jump (CMJ) and drop jump (DJ) of 40/60 cm box were performed on two independent and synchronized force platforms (Bilateral Tensiometric Platform S2P, Ljubljana, Slovenia). The measurement of a standing long jump (SLJ) and all continuous jumps: standing five jumps (SFJ), standing bounce triple jump (SBTJ), five double-leg jumps (FD-LJ), and a 10 m horizontal single leg jump (HSLJ-10mL/R) were performed using OptoJump–Next Microgate (OptoJump, Bolzano, Italy). Results: Statistically significant differences were noted in all jump kinematic and somatic parameters, in favor of the men. The correlations between values of height of symmetrical jumps (bilateral) and distance (SLJ) were stronger in women despite the shorter jumps than the men. When an alpha-level of 0.01 was set, this study demonstrated a stronger correlation between symmetrical-single and asymmetrical-continuous plyometrics exercises and sprints, both men and women. This relationship is due to their similar kinematic and dynamic structures with sprinting steps. Conclusions: The results showed a large dispersion of the relationship (p < 0.05) between jumps and sprints divided into 10, 20 and 30 m, both in men and women. Both types of exercises implemented as a plyometric training regime are an extremely important tool for sprint speed development.

This study was conducted to assess gender and age differences among 73 men and women (50—59, 60—69, and 70—79 yr.) on five motor tasks (balance, standing long jump, sit and reach, hand grip, and Softball throw). Differences between men and women on the standing long jump, hand grip, and the Softball throw favored men. The men had better performance scores than the women on each of these tasks. An interaction of gender by age was noted on the balance task. Women 50—59 yr. old balanced significantly longer than the men of that age group. Age differences were found for the standing long jump, hand grip, and Softball throw. The 50—59 age group performed significantly better than the 60—69 and the 70—79 age groups Performance decreased on each task across age groups. These findings suggest gender differences in motor performance of older adults as has been noted for children.

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 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.

The Relationship

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 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.

Mediation And Moderation

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.

Objectives:The aim of this study was to analyze the effects of an 8-week (conducted biweekly for a total of 16 sessions) plyometric training program (PT) (e.g., upper- and lower-body exercises) combined with regular tennis training on physical qualities in young tennis players.Design:Sixty tennis players between the ages of 12 and 13 years (age 12.5 ± 0.3 years, weight 44.2 ± 7.0 kg, height 156.6 ± 7.1 cm) were allocated to either the control group (standard in-season regimen) (CG; n = 30) or the experimental group, which received an additional PT (TG; n = 30) for 30–60 min as a substitute for some tennis training within the usual 90-min practice.Methods:Pre- and posttests included: anthropometric measures; vertical countermovement jump (CMJ); standing long jump (SLJ); 20 m sprint time (with 5 and 10 m splits); a modified 505 agility test; overhead medicine ball throw; and serve velocity test.Results:After the training intervention, the TG showed significant (p < .01) improvements in all the parameters analyzed, with percentages of change and effect sizes ranging from 3.1% to 10.1% and 0.4 (small) to 1.3 (moderate), respectively. No significant changes were observed in the CG after the training intervention.Conclusions:PT was shown as an important stimulus for enhancing explosive actions in young tennis players.
