Repeated sprint efforts have been identified as a key component of physical fitness in team sports, such basketball. The high intensity efforts required throughout the game will generate fatigue, and the inability to maintain initial velocity/force levels, thus, decreasing performance and hence instituting muscle fatigue. A strategy to increase performance and delaying the manifestation of fatigue can be post-activation potentiation (PAP). PAP is defined as enhanced involuntary twitch in response of a prior voluntary contraction and has been inserted into the warm-up routine leading to improved performance. In addition, specific PAP application to mode of exercise showed better results than a PAP non-specific to sport. Therefore, the objective of this present study will be to investigate the effect of two specifics PAP protocols on performance in repeated sprint efforts with changes on direction in basketball players and in fatigue manifestation. Fifteen basketball players will be participate and perform a randomized cross-mode experimental procedures. During each session, subjects will undergo a standardized warm-up for all conditions, after warm-up will be realize the neuromuscular measurements and then submitted to PAP (heavy sled sprint and drop jump) or control protocol. After 4 minutes of the end of the experimental protocol will be measured the performance in the repeated sprint test, and immediately after the test is finished the neuromuscular measurements. (AU)
