Abstract

The purpose of this study was to measure the acute effect of two maximum strength sessions on immediately subsequent mechanical performance. In order to do that, 1 repetition maximum (1RM) and maximum power load of concentric bench press exercise were obtained in 10 men. The experimental procedure begun five days after and it involved two training sessions. 6 bouts of 2 repetitions at 90% 1RM of concentric bench press were developed in every session with a minimum rest period of three minutes. Power developed with maximum power load and with 90% 1RM were measured before and immediately after every training day. The dates did not show significant differences between measurements with maximum power load. Performance with 90% 1RM was significantly lower (p<0.05) in second session. 1RM did not correlate with performance differences after-before session with maximum power load. Correlation was statistically significant between 1RM and both real and percentage values of differences after-before session with 90% 1RM load in the first training day (r = –0.631 y r = –0.678 respectively).
