Changes in Vertical Jump Height and Sprint Time During a Congested Match Schedule in Youth Female Soccer Players

Abstract

Purpose: The purpose of this study was to examine changes in jump height and sprint time and to assess the relationship between relative changes in jump height and accumulated training load during a congested match schedule in youth female soccer players. Methods: This study included data from 14 youth female soccer players who performed countermovement jump testing pre- and post-match, post-tournament, as well as sprint testing pre- and post-tournament. A one-way repeated measures ANOVA was conducted to compare changes in jump height over the course of the tournament. A paired sample t-test was performed to compare sprint time between pre- and post-tournament, and Pearson product moment correlations were used to determine the relationship between percent change in jump height and accumulated training load. Results: Jump height decreased significantly (p < 0.001) between time periods during the tournament, and sprint time increased significantly (p = 0.001). There was no significant relationship between percent change in jump height and accumulated training load. Conclusion: This study found that jump height decreased over the course of the tournament and there was a significant increase in sprint time from pre- to post-tournament. Applications in Sport: These results suggest that appropriate recovery strategies and training are needed to assist players in coping with the demands of a congested youth soccer schedule.

ABSTRACT

To be successful in field sports such as soccer, rugby, football and hockey, players need to be enhancing some bio-motor abilities like endurance, strength, speed and flexibility. The purpose of this study was to investigate the effects of national-level field hockey on physical fitness and body-composition parameters in Turkish females. Twenty-four female subjects (12 non-sporting healthy controls aged 19 to 22, 12 elite, national level field hockey players aged 18 to 21) participated in this study. Body composition, 30-meter sprint, leg power, handgrip strength, posture balance were measured. At the end of measurements, there was a significant differences in body-fat percentage (p < 0.014), fat mass (p < 0.044), speed (p < 0.000), leg power (p < 0.006), grip strength (p < 0.022), but no significant differences in fat-free mass (p > 0.442) and fall index (p > 0.258) were observed between hockey players and non-sporting controls. Results suggest that regular participation to hockey training programs improves body composition, speed, and lower- and upper-extremity strength, with no effect on fat-free mass and posture balance in young females. Additional studies may identify effects of field hockey training on physical fitness and body composition in males and different age groups.

Key words: Field hockey, fat mass, speed, strength, posture balance

ABSTRACT

The objectives of the present study were: a) to assess normative profiles for the serve speed of peak-performance volleyball players in order to guide practice sessions for men´s teams (study 1) and women´s teams (study 2), and b) to establish the possibilities and the ranges of speed that a volleyball throwing machine can offer for working on reception in volleyball (study 3). In studies 1 and 2, the serve techniques and the maximal speeds were analysed in men´s (2097 serves) and women´s (2056 serves) volleyball. Study 3 consisted of analysing the release speeds of the ball that are generated from the various speed settings that can be programmed with the throwing machine. The results provide normative profiles for the ranges of speed of the different types of serve for both men´s and women´s volleyball. Additionally, they indicate the speeds that a volleyball throwing machine provides for reception training in volleyball.
