Effects of Integrating a Plyometric Training Program During Physical Education Classes on Ballistic Neuromuscular Performance

Abstract

Objective: This study examined the effects of a short-duration plyometric training program during physical education on neuromuscular ballistic performance in youth. Methods: Thirty-two students were assigned to a control group (CG; n = 16; age: 16.76 ± 0.72 years; height: 1.66 ± 0.09 m; body mass: 61.38 ± 6.07 kg) or an experimental group (EG; n = 16; age: 16.56 ± 0.62 years; height: 1.69 ± 0.09 m; body mass: 61.90 ± 7.83 kg). Both groups completed pre- and post-intervention Countermovement Jump (CMJ) tests using force plates. Over a four-week period, the EG completed eight sessions. Both the EG and the CG participated in 40 min sessions incorporating speed games, directional changes, and agility exercises. Paired t-tests and Cohen’s d were used for analysis. Results: The EG showed significant improvements in jump height (p = 0.006, ES = 0.83), jump momentum (p = 0.008, ES = 0.80), and take-off velocity (p = 0.003, ES = 0.93), with a decrease in peak propulsive power (p = 0.01, ES = 0.77). In contrast, the CG exhibited declines in multiple metrics, including jump height, jump momentum, and take-off velocity. Conclusions: These findings suggest that integrating plyometric training into physical education classes can effectively enhance neuromuscular performance in youth. Implementing structured training protocols within school programs may optimize strength, power, and movement efficiency, benefiting long-term athletic development.
