Efeito de diferentes volumes semanais de treino baseado na carga ótima na potência de jovens atletas

The aim of this study was to analyze the effect of training based on optimal power load with 3 or 6 weekly sets for squat (SQ) and deadlift (DL). Fourteen athletes (5 females) with a mean age of 17.86 ± 1.46 years were divided into two groups (3S and 6S) who performed 3 or 6 sets of 6 repetitions of DL and SQ, respectively. Mean Propulsive Velocity (MPV) and Relative Optimal Power (ROP) variables in DL and SQ were evaluated with a progressive load test. Data from the repetition with the highest absolute power during the test were retained for analysis. The T-test was used to compare the pre moment data between the two groups and the difference between pre and post moments for each group. Cohen's d was calculated for effect size. The significance level was set at p > 0.05. Groups were similar for all variables at pre-moment. In pre vs post comparisons, only significant improvement was observed in the ROP of SQ for the 6S group (28.83w/kg vs 33.22w/kg; p = 0.01; d = 1.47). Only the group performing a higher training volume, 6S, showed improvement in power performance. Therefore, it seems that a higher volume over a 4-week training period is necessary to generate power gains in this population. Future studies should be conducted to verify if these differences directly impact sports performance.
