Abstract EN

The purpose of this study was to identify the effect of Contrasting plyometric and weight training program on Some Physical Abilities and selected biomechanical variables to enhance the Volleyball float serve from jump Performance for Female.

Ten female volleyball juniors from Sporting Club (age 15.6 ± 0.33, Height 169.2 ± 3.3 cm, weight 63.9.13 ± 8.2 kg, and training age 7.5 ± 0.64).

Physical abilities were also measured.

Each player performed three trials of float serve pre and post- measurements the best one was chosen for biomechanical analysis.

Data were collected using (Fastec inline camera 125 Hz), the biomechanic analysis was done using (Kinovea 0.8.15).

The main results showed statistically significant differences between premeasurements and post-measurements in some physical abilities and biomechanics variables.

The study concludes that Contrasting of plyometric and weight training program had a positive effect on improving the volleyball float serve from jump performance for females.
