The present research focused its efforts on discovering methodological alternatives that benefit the possibility of applying high levels of strength in the straight punch, thus favoring the probability of a victory by knockout. The working hypothesis proposed that, if exercises with a post-activation performance enhancement effect are used, the strength applied to the straight punch can be increased. This quasi-experiment aimed to determine the acute effects of post activation performance enhancement on the strength applied to the straight punch, using the bench press or the Landmine as the conditioning activity. It was worked with 20 boxers (eight professional and 12 amateur), and the population was divided into two groups, matched according to body weight. The maximum impact strength was evaluated with a load cell model WLCC01, then the maximum dynamic strength was determined for each exercise, and from this data, a load was placed to mobilize 60% of the maximum dynamic strength, performing repetitions until the speed of the movement decreased by more than 10 %. Then, the maximum impact strength was re-evaluated. Records were taken immediately after, at one, two, three, four and five minutes. The results showed an increase of 9.3 % in the bench press group and 12.46 % in the Landmine group. It was concluded that both exercises, when used as conditioning activity, generate a significant increase (p 0.05) of the maximum impact strength in the straight punch.
