Abstract :This study primarily aims to [1] investigate the relationship between hamstring muscle strength and vertical jump performance in athletes from football, volleyball, basketball, handball, and individual sports and [2] identify differences in eccentric hamstring strength based on athletes\\\' performance indicators. A total of 107 athletes aged 18-22 years, engaging in exercise 3 to 5 days per week with no history of injuries in the past six months, participated in the study. Vertical jump performance was measured using the iVMES Athlete device, while eccentric hamstring muscle strength was assessed with the iVMES H-BORD system. Data analysis was conducted using SPSS 23. Skewness and kurtosis values between -2 and +2 were used to confirm normal data distribution. One-way ANOVA was applied for comparisons among three or more variables, Pearson correlation coefficient analysis was used to evaluate relationships between variables, and frequency analysis was conducted to determine the distribution of variables. Descriptive statistics, including means and standard deviations, were calculated, and a significance level of p <.05 was adopted for all analyses. The results revealed a significant relationship between unilateral (right-left leg) hamstring strength and the corresponding leg’s vertical jump performance. Football players demonstrated significantly higher hamstring strength compared to athletes from other sports disciplines. This finding suggests that the demands for high-speed and explosive movements in football may promote hamstring muscle development. The study highlights the differences in hamstring strength among athletes in different sports and underscores the critical role of hamstring muscle strength in vertical jump performance. Additionally, it emphasizes the importance of sport-specific training programs in improving athletes\\\' hamstring strength and jump performance. Future research is recommended to examine the long-term impact of hamstring strength imbalances on injury risk in greater detail.
