Title: Evaluation of post-activation potentiation effect on performance indicators of sprint following crouch start Objectives: The main objective of this thesis is to evaluate the influence of post- activation potentiation phenomenon on sprinter step performance indicators following crouch start by using Optojump system. Secondary objectives are firstly - to complile systematic up-to-date review based on recently published evidence, and secondly - to compare acquired results with current trends described in this review. Methods: Fifteen (n = 15) moderate to well trained male athletes completed the experimental procol of controlled sprints (20 m), activation of post-activation potentiation / post-activation performance enhancement elicited by series of squats (3 series, 5 repetition, load of 75 % of 1RM, resting interval 2 mins). Following the activation, all participants completed 1x20 m of sprinting performance from crouch start at 5 min, 10 min, 20 min and 40 min. All measurments were made by using the Optojump system. Acquired measurments were further analyzed and statistically evaluated. Results: Evaluation of acquired data did not result in significant positive effect of activation protocol on measured variables. Furthemore, series of squats were associated with decreased peak velocity and...
