The Relationship Between Reactive Strength Index, Eccentric Utilization Ratio, Pre-Stretch Augmentation Percentage and Leg Stiffness in Elite Female Volleyball Players: Correlational Research
Abstract
Objective: This study examined the relationships between Reactive Strength Index, leg stiffness, eccentric utilization ratio, and pre-stretch augmentation percentage in elite female volleyball players. Material and Methods: Fourteen athletes performed squat jump, countermovement jump, and drop jump tests over 3 measurement days. An optical measurement system was used to assess ground reaction forces. Data normality was assessed using the Shapiro-Wilk test. Pearson's correlation was applied to normally distributed variables, while Spearman's correlation was used for non-normally distributed variables. Statistical significance level was determined as p
