Effects of Plyometric Training on Sprint Speed and Vertical Jump Performance in Soccer Players: A Randomized Controlled Trial

Abstract

Background: Sprint speed and vertical jump performance are important physical attributes for soccer players, contributing to acceleration, explosive movements, jumping, and overall match performance. Plyometric training may improve these attributes through enhanced neuromuscular function and lower-limb power.
Objective: To investigate the effects of a structured plyometric training programme on sprint speed and vertical jump performance among male soccer players.
Methods: Forty male soccer players aged 18–24 years were randomly allocated to an experimental group (n = 20) or a control group (n = 20). The experimental group performed plyometric training alongside regular soccer practice, whereas the control group continued regular soccer practice alone. The intervention lasted 12 weeks. Sprint speed was assessed using the 40-metre linear sprint test, and lower-limb explosive power was assessed using the vertical jump test. Both groups completed pre-test and post-test assessments. Data were analysed using descriptive and ANCOVA statistics, with statistical significance set at p < 0.05.
Results: The study revealed significant between-group differences in post-test vertical jump performance [F (1, 37) = 286.86, p < .001, partial η² = .886] and 40-metre sprint performance [F (1, 37) = 86.00, p < .001, partial η² = .699], favouring the experimental group after adjusting for baseline scores.
Conclusion: This randomized controlled trial investigates whether incorporating structured plyometric exercises into regular soccer training provides additional benefits for sprint speed and vertical jump performance.
