AbstractBackground: Countermovement vertical jump is a crucial skill in many sports. Plyometric training is a prevalent method to improve athletes' jumping ability. Objectives: The present study aimed to investigate the effect of a 6-week plyometric training on the kinematics of take-off and countermovement vertical jump height. Methods: Fifteen young, healthy male subjects performed plyometric exercises in three sessions per week for six weeks. Digital videos of pre-training and post-training jumps were captured. The Kinovea software was used to measure the kinematic parameters of take-off in the sagittal plane. Pre and post-training values were compared by paired sample t-test with the statistical significance level of P < 0.05. Results: Post-training results showed a higher jump height (P < 0.05), more flexed shoulder, and more extensive hip and knee at take-off (P < 0.05). Also, while hip extension velocity was decreased, shoulder flexion and knee extension velocities were significantly increased (P < 0.05). Conclusions: The 6-week plyometric training, including 720 jumps, improved shoulder flexion, and hip and knee extensions at take-off, resulting in high CMJ height. We employed plyometric training to improve the shoulder flexion and hip and knee extension velocities and increase CMJ height.en
