Investigation of the Relationship Between Hip Muscle Strength and Athletic Performance: A Study on Elite Athletes

Background: Athlete performance refers to an individual's ability to execute physical tasks efficiently and effectively within their sport, encompassing strength, power, endurance, agility, flexibility, and coordination.Key determinants such as muscular strength and motor skill proficiency collectively influence athletic outcomes.Muscles responsible for hip flexion, extension, rotation, abduction, and adduction serve distinct functions.However, limited research has identified which specific muscles most significantly influence jump height (JH), peak power (PP), reactive pro agility (RPA), and the relative strength index (RSI). Materials and Methods:A total of 34 athletes were included in the study, with performance measurements obtained using the Vald performance analysis systems.Results: Correlation analysis indicated that JH, PP, RSI, and RPA were significantly associated with hip extension right strength (HER).In addition, JH was significantly associated with left hip flexor (HFL) strength.However, linear regression analysis revealed that HER and HFL strengths significantly influenced JH, whereas HER strength influenced RSI.HER also had a notable impact on RPA and PP.Conclusion: These findings provide valuable insights into the role of HER in key athletic performance metrics.By identifying key muscle groups influencing JH, reactive strength, and agility, this study supports the development of targeted strength training programs for professional athletes.
