The influence of rest intervals following low-load countermovement jumps in athletes
Original language description
Introduction. A countermovement jump (CMJ) is a common explosive activity used to measure lower body power. Determining an optimal rest interval may be beneficial in creating a training program to improve performance. Aim of Study. To investigate the post-activation potentiation (PAP) effect of different low-load, high-intensity CMJs on subsequent bodyweight CMJs. Material and Methods. On four different occasions, 18 athletes (age: 19.61 +- 0.98 y; height: 177.69 +- +- 11.35 cm; mass: 80.22 +- 11.96 kg) completed one baseline CMJ followed by a series of low-load, high-intensity CMJs (0%, 10%, and 20% of their back squat one repetition maximum [1RM]) and one control condition without a CMJ (NJ). For each low-load intervention, participants completed 1 set of 6 CMJs, except NJ where participants stood for 20-seconds. Then, participants performed single CMJs at 8 different rest intervals following the experimental and control conditions. Three, 4 x 9 (condition [NJ, 0%, 10%, and 20%] x time [baseline, 0.5-min, 1-min, 2-min, 4-min, 6-min, 8-min, 10-min, and 12-min]), and three, 4 x 2 (condition x time [baseline and peak]) repeated measures analysis of variance were used to analyze jump height (JH), estimated power (eP), and flight time (FT) via a jump mat. Results. There were no protocol x time interactions. However, there was a significant (p < 0.05) main effect for time for FT, where FT was longer at 2-min than 10-min, and FT was longer at 4-min than 8-, 10-, and 12-min. Peak JH, eP, and FT values were all significantly greater than baseline. Conclusions. A single warm-up jump may enhance jump performance and other low-loads investigated in this study. The effectiveness of a low-load PAP response may be highly dependent upon the individuals. Thus, a greater focus on individualized PAP programming is needed.
