The current study aimed to know the effect of post activation potentiation during warm-up using the vertical drop jump on both the muscular ability of the lower extremities and the reactive agility of female volleyball players. The study sample consisted of 15 female players from the Aviation Club first – team (age: 21,96 ± 1.80 years), (body mass: 68.96 ± 8,13 kg), (height: 172,35 ± 4 , 39 m). The experimental method with a single experimental group was used with a measurement design (pre- and post-test). The vertical drop jump test using the Axon jump was used to measure the muscular ability of the lower extremities, and the test (9, 3, 6, 3, 9) to measure reactive agility. The measurements were carried out in two parts: the first part was the pre-test, in which the values of the two tests under study were determined, And the second part, in which the post-test was carried out after applying the post activation potentiation in 5 m and after the pre-test in 48 hours. The results showed positive sharp muscle activation in improving the muscular capacity values of the lower extremities represented by the jump height in addition to the improvement in speed in the interactive agility test.
