Therefore, the purpose of the present study was to investigate the effect of dynamic warming and dynamic warming with PAP on power of muscle and agility in girls’ volleyball player.<br /><strong>Methods</strong>: In this study, 36 female volleyball players were selected and performed two types of dynamic warm-up and dynamic warm-up with PAP using the Counterbalance method. The dynamic protocol consisted of dynamic stretching exercises and the dynamic warm-up protocol with PAP includes warm-up with dynamic stretching plus three movements: 1- Scott, 2- 10 meter running by attaching load of 5% of body weight and 3- jumping with load of 5% body weight. Then the Sargent, Bosco jump and T tests were performed before and 4, 6,9-11, and ultimately 30 minutes after the end of protocols were completed, respectively. Data were analyzed using independent t-test, dependent t-test, and linear modeling mixed with covariance at a significant level of P<0.05.<br /><strong>Results</strong>: The results showed that there was no significant difference between the warming protocols in the Sargent jump and the Bosco test at any of the measurement times (P<0.005). 48 hours after exercise in both warm-ups, agility was significantly improved. Also, the dynamic warm-up with PAP showed a significant effect of group at the air time (AT) standing in 30 minutes after the end of protocol (P<0.005).<br /><strong>Conclusion</strong>: Finally, the findings of the present study show that There was no difference between dynamic and dynamic warm-up with PAP methods with PAP in power of muscle and agility in girls' volleyball player. <strong>purpose</strong>: One of the effective mechanisms for better jumping in athletes is the induction of PAP in the warm-up protocol.
