Tennis is considered to be an explosive sport and the performance requires developed motor skills. Therefore, Plyometrics is widely known to contribute to improvements in jumping ability in Tennis. The objective of the present study was to explore the effect of a plyometric training program of 6 weeks (2 sessions per week the first two weeks and 3 sessions per week the last 4 weeks) on the performance of jumping in young Tunisian tennis players, aged 16 years. Twenty-four (24) Tunisian tennis players (16 years old), voluntarily participated in this study and were randomly assigned to two different groups: an experimental group (EG, n = 12) and a control group (CG, n = 12). The results indicate a significant improvement in the height of the Countermovement Jump test vertical trigger and squat jump in the experimental group respectively of 12% and 13%.
