Tennis is a physically demanding sport that requires quick movements, rapid changes of direction, and powerful strokes. Core stabilization is essential for maintaining good posture, generating force, and reducing injury risk. This interventional study aimed to investigate the effectiveness of core stabilization exercises on lumbopelvic rhythm, speed, and agility in adolescent tennis players. Thus, the aim of this study was to assess the impact of core stabilization exercises on lumbopelvic rhythm, speed, and agility in adolescent tennis players. 45 participants (Age 15.66 year’s ± 1.14 years) of both genders: 31 male (height 154.23± 6.67CM weight 48.30±6.36kg) (B.M.I 20.04±1.39) and 14 female (height 15.79±1.05 CM weight 49.29±5.41Kg) (B.M.I 20.54±1.67) with 6 months to 2 years of tennis experience were included in this interventional study. Participant’s pre and post data were collected for lumbopelvic rhythm (Schobers test), speed (30 m sprint test) and agility (T- test). The study results showed significant improvements in lumbopelvic rhythm, speed, and agility among the participants following the core stabilization exercise program. These training programs can enhance athletic performance and reduce injury risk.
