Upper Limbs Strength Training With Individual Maximal Power Loads: Analysis Of Acute Effects On Mechanical Power

Abstract

The purpose of this study was to measure the acute effect of two explosive strength sessions on mechanical performance. In order to do that, 1 repetition maximum and maximum power load were obtained in 9 men. The experimental procedure begun five days after and it involved two training sessions. 7 bouts of 3 repetitions at maximum power load of bench press were developed in every session with a minimum rest period of three minutes. Power developed at 90% 1RM and at maximum power load were measured before and after every training day. Finally it was carried out a postest measuring. Although repeted-measures ANOVA showed significant differences between measurements at 90% 1RM , statistics analysis did not show significant differences regarding to before-after every sessions contrasts, and between measuring at maximum power load. Also, we did not find significant 1RM correlation with performance differences before-after session. Finally, it was found significant correlation between maximum strength and % 1RM associated to developed maximum power at postest.
