Introduction: Lower-limb muscle strength is crucial in badminton for jumping, striking, rapid movement, and changing direction. Plyometric training uses the stretch-shortening cycle to improve explosive strength. This study aimed to determine plyometric training effects on lower-limb muscle strength among badminton players at SMAN Olahraga and compare changes between experimental and control groups. Methods: This quantitative experimental study used a pretest/posttest control group design. Thirty-two players were divided into an experimental group receiving plyometric training and a control group receiving no training. Lower-limb strength was measured using vertical jump test before and after intervention. Program consisted of twelve sessions. Data were analyzed using statistical tests with significance p < 0.05. Results: The experimental group showed increased lower-limb strength after plyometric training, with a significant difference between pre- and post-training measurements. The control group showed no significant changes. A significant between-group difference was found, indicating that plyometric training improves lower-limb strength in badminton players. Discussion/Conclusion: From sports physiotherapy perspective, plyometric training enhances neuromuscular function and explosive lower-limb strength, supporting badminton performance. Training programs should be tailored to each player’s physical condition and capabilities to achieve results.
