dc.description.abstractThe purpose of this study was to compare the effects of two protocols of post-activation potentiation (PAP) on swim start performance (SS). Fourteen trained swimmers (10 men and 4 women) voluntereed for this study. An intra-group design of randomised repetitive measurements was applied. A previous SS trial, performed after a standard warm up (SWU), served as a reference. Two methods of PAP, performed after one hour of rest, were randomly added to SWU: i) three lunges at 85% of 1 repetition maximum (LWU), and ii) four repetitions on the flywheel device YoYo squat (YWU). Swimmers were tested in an SS eigth minutes after the PAP warm-ups. Kinematic variables were collected using three underwater digital video cameras fixed poolside and operating at 25 Hz, and one high speed camera focused on the block and operating at 300 Hz. Data obtained from the video analysis were processed using a repeated measures analysis of the variance. The mean horizontal velocity of the swimmer's flight improved after both PAP methods, with the greatest improvement after YWU (F2,12= 47.042, p < 0.001; SWU = 3.63±0.11; LWU = 4.15 ± 0.12; YWU = 4.89 ± 0.12 m/s). After YWU, it took the subjects less time to cover a distance of five meters (F2,12 = 24.453, p < 0.001) and fifteen meters (F2,12 = 4.262, p < 0.04). Subjects also achieved a higher mean angular velocity of the knee extension (F2,12 = 23.286, p < 0.001) and a reduction of the time on the block (F2,12 = 6.595, p < 0.05). These results demonstrate that muscle performance in the execution of an SS is enhanced after a warm-up with specific PAP protocols. YWU leads to the greatest improvement in the performance of the swimmer 's start and, therefore, may be specially beneficial in short events.es_ES
