TAILIEUCHUNG - Human thrust in aquatic environment: The effect of post-activation potentiation on flutter kick

Herein, we analyse by experimental techniques the human kicking thrust and measure the effect of a warm-up routine that includes post-activation potentiation (PAP) sets on front-crawl flutter kick thrust, kinematics, and performance. Sixteen male competitive swimmers with ± years of age were randomly assigned in a crossover manner to undergo a standard warm-up (non-PAP; control condition) and a warm-up that included PAP sets (PAP; experimental condition) consisting in 2 5 repetitions of unloaded countermovement jump. Participants performed a 25 m all-out trial in front-crawl with only flutter kicks eight min after each warm-up. Kinetics (., peak thrust, mean thrust, and thrust-time integral) and kinematics (., speed, speed fluctuation and kicking frequency) were experimentally collected by an in-house customized system composed of differential pressure sensors, speedo-meter, and underwater camera. Peak thrust (P = , d = ) and mean thrust (P = , d = ) were increased by 15% in PAP compared to non-PAP. Large and significant differences were noted in speed (P = , d = ) and speed fluctuation (P = , d = ), which improved by 10% in PAP compared with non-PAP. In conclusion, a warm-up that includes PAP sets improves kicking thrust, kinematics and performance. | Human thrust in aquatic environment: The effect of post-activation potentiation on flutter kick
