Potenciação pós-ativação exerce efeito ergogênico na velocidade de nadadores: uma revisão sistemática com metanálise

Abstract

This study was carried out with the objective of review and analyze studies that measured the effect of post-activation potentiation (PAP) on the performance of swimmers. Methods: a systematic review was carried out with meta-analysis based on descriptors related to post-activation potentiation in swimming. A total of 132 articles were identified, of which 10 were selected. Comparisons between the PAP condition and the conventional warm-up (Control) were performed for the following set of variables: a) power in 50- and 100-meter events; b) start performance; c) test time of 50- and 100- meters and d); partial and full speed in 50 meters events. Results: the data extracted from the studies showed acceptable homogeneity (I²=0.000). When we observed the confidence intervals, it was verified that there were no differences between the PAP condition and the Control for power in 50 and 100 m events (Hedges g'=-0.12; 95%CI=-0.376; 0.136; p=0.357); time in 50- and 100-meters race (Hedges g'=-0.131; 95%CI=-0.319; 0.057; p=0.172); start performance (Hedges g'=-0.018; IC95%=-0.569; 0.21; p=0.366). The PAP condition had an ergogenic effect for partial and total velocity in the 50 m event (Hedges g'=-0.254; 95%CI=-0.498; -0.01; p=0.041). Conclusion: the present meta-analysis concluded that, for the set of variables analyzed, the PAP intervention does not exert an ergogenic effect on the performance of swimmers, except for partial and total velocity in 50 m events. Considering the small number of quality articles published on this topic, further studies are suggested.
