Effects of different sprint training programs with ball on explosive, high-intensity and endurance-intensive performances in male young soccer players

This study compared the effects of different sprint ball-based training programs on fitness-related performances in youth soccer players. Forty male players (age: 15.2 ± 0.6 yrs) participated in a short-term (8 weeks) randomized parallel fully controlled training study, with pre-to-post measurements. Players were randomly assigned to 3 sprint ball-based training groups: training with combined sprint (performing linear and change of direction sprints; CST), or using linear sprint (LST), or performing sprint with change of direction (CODT) and to a control group (CONT). Pre- and post-training players completed a test battery involving linear sprinting (10 and 20 m, and flying 10 m), 505 test (COD), 15 m test with ball (CODB), countermovement jump test (CMJ test) and maximal oxygen consumption (VO2max). All physical performance’ variables improved after the training intervention (all p < 0.05; ES ≥ 0.2). No main effect of groups was observed in linear sprinting, CMJ and VO2max (p > 0.05; ES < 0.2). A training group main effect was found (p < 0.0001; ES = 0.50) for COD with CODT induced better performance than LST and CONT (all p <0.0001; ES > 0.8). Also, a training group main effect (p = 0.009; ES = 0.35) was found for CODB with CODT elicited better performance than LST and CONT (all p = 0.001; ES > 0.80). Our findings suggest that ball-based training programs were more effective to improve fitness levels in youth players during the in-season period and that CODT modality was more effective to improve COD and CODB performances.

Physical Skills in Male Volleyball Players 14-18 Years Old

During the monitoring of volleyball teams in Albania during training, it was noticed that coaches pay more attention to technical elements and not to physical abilities to ages 14-18 years. The aim of this study was to find out the trend of improvement and differences with the age on physical abilities of male’s volleyball players in Albania. Methods: Participants in this study were N=43 volleyball players from two age categories; N=21, cadet (14-16 yrs.), N= 22 and junior (16-18 yrs.) Measurement for anthropometrics (body weight, body height) and physical abilities (push up test, curl-up test, standing long jump and vertical jump test) were assessed. Results: Analysis between two age categories shows significant differences. Showed results for anthropometrics and also for physical abilities showed differences between groups of volleyball players. Data of this study for jumping performance using vertical jump CMJ test between groups for cadet vs. junior data show (mean difference= 21.3 cm; Sig= 0.004) while for vertical jump Run up test between groups for cadet vs. junior data show (mean difference= 22.3 cm; Sig= 0.003). Conclusion: In the best interest of the study, it would be good if other teams were involved from different cities of Albania. Suggestions for other studies we recommend in comparing data by positions in the field. Trainers should plan training with these age groups different coordination programs not only technical. This study has limitations with regards to the sampling number of male volleyball players, which is justified for not having sufficient funds.

Relative Age Effect and Talent Identification in Youth Volleyball Players from the Polish Volleyball Federation Sports School

Introduction. This study sought to determine differences in the quarterly age distribution of young Polish volleyball players from the Sports School of the Polish Volleyball Federation (SS PVF), to investigate quarterly differences in anthropometric characteristics and jump test results. Material and Methods. RAE of young players from SS PVF (n = 232) born between 1989 and 2002 was identified in the course of the research. Furthermore, the study included anthropometric characteristics and jump test results (attack jump – AJ). Results. The chi-square test (χ2) revealed the overrepresentation of volleyball players born in quarters 1 and 2, both in the case of graduates (χ2 = 27.32, p < 0.0001) and students who did not finish school (χ2 = 17.95, p < 0.0005). Two-way ANOVA for unbalanced data for the Group factor showed significant differences in the value of estimated marginal means in the case of AJ (F(1,214) = 5.907, p < 0.016) and body mass (BM) (F(1,214) = 5.348, p < 0.022). Conclusions. These results point to the need for better understanding of RAE in order to avoid dropping out or the loss of potential talent, which will contribute to even greater development of volleyball in Poland.

The effect of body composition on strength and power in male and female students

Purpose The aim of this study is to determine and to compare the effect of sex differences in percentage of body fat on the strength and power performances of the legs and arms during short maximal exercise. Methods 72 male and 64 female students aged 20 to 23 years were enrolled in this study. After assessing their morphological characteristics (body mass, height and percentage of fat mass), a squat jump test (SJ), a 5 successive jump test (5JT), a hand gripping (HG) and back strength (BS) tests have been conducted for each subject. Male students were re-tested after being weighed down with a weight equivalent to the mean differences in body fat recorded between the two sexes in the form of a loaded worn vest. Results Male are 15.7% heavier and 7.4% taller and presented a percentage of fat mass (17.2 ± 1.8%) significantly (p < 0.001) lower than that of women subject (25.0 ± 2.5%) (difference male vs female for fat mass: -45.5%). HG, BS, 5JT and SJ performances were significantly higher in males (44 ± 5 kg, 141 ± 2 kg, 11 ± 1 m and 32.4 ± 2,7 cm, respectively) than in females (31.0 ± 4 kg, 81.6 ± 13 kg, 8.7 ± 0.7 m and 21.1 ± 1.9 cm, respectively). In the control (unloaded) condition, the relative difference between males and females represented 23.5% and 34.7% of the male performances for 5JT and SJ, respectively. In the weighted condition, the relative difference between weighted males and females still represented 11.7% and 23.8% of the weighted male performances for 5JT and SJ, respectively. Cancelling the sex difference in fat mass by adding weight in males reduced by 50.1% the sex difference during 5JT and 31.4% and 71.7% for hight and power results, respectively during SJ test. Conclusion During short and maximal exercise, male performed better with their hands, back and legs than female students. Excess fat for female students has a disadvantageous effect on vertical and horizontal jumps performances. The persistence of sex differences after weighting of male students indicates that body fat is responsible for 30 to 70% of the observed differences between sexes performances and power outcomes during jump tests.
