|
PURPOSE: This study examined the effects of various interventions for improving the hip joint range of motion on elite badminton players, including body balance ability, jumping power, smash speed, and joint range of motion.
METHODS: The study was conducted on elite badminton players belonging to the S badminton team in Yongin, Gyeonggi-do, and the M badminton team in Suwon, Gyeonggi-do. Twenty-one elite badminton players were selected; they were assigned randomly to Experimental Group 1 (n = 11) and Experimental Group 2 (n = 10). Before and after the intervention, the hip joint range of motion, modified star excursion balance test, Sargent jump, and smash speed were measured. In Experimental Group 1, hip joint manual mobilization was applied by a physical therapist, and hip self-exercise performed by the athletes was applied in Experimental Group 2. This intervention was applied once a day, three times a week, for four weeks.
RESULTS: A significant increase in the hip joint range of motion (flexion and extension) and modified star excursion balance test (posteromedial direction) was observed in Experimental Group 1 (hip joint mobilization applied group) compared to Experimental Group 2 (hip joint self-exercise applied group) (p < .05).
CONCLUSION: When elite level badminton players require improvement in hip flexion and extension range of motion and posteromedial body balance, hip joint mobilization is more effective than hip self-exercise application.
