In comparison with the body of evidence on aquatic animals thrust, the knowledge on human thrust in water is very limited. Since a long time ago, substantial research using different experimental techniques, simulations, and modelling procedures have been conducted on the thrust of aquatic specimens, ,,. Several aquatic specimens, such as dolphins, are fully adapted to maximize propulsion and minimize drag. Swim acceleration is the net resultant of drag and propulsive forces acting on a body. Human beings encounter numerous challenges to move in water as compared to aquatic animals. In conclusion, a warm-up that includes PAP sets improves kicking thrust, kinematics and performance. Large and significant differences were noted in speed ( P = 0.01, d = 0.54) and speed fluctuation ( P = 0.02, d = 0.58), which improved by 10% in PAP compared with non-PAP. Kinetics (i.e., peak thrust, mean thrust, and thrust-time integral) and kinematics (i.e., 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.
Another name for flutter kicks exercise trial#
Participants performed a 25 m all-out trial in front-crawl with only flutter kicks eight min after each warm-up. Sixteen male competitive swimmers with 22.13 ± 3.84 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. 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.
