Treinamento resistido e diferentes intervalos de recuperação em idosos: uma revisão de escopo

Abstract

The objective of the present study was to identify the main responses generated by different recovery intervals (RI) between sets in resistance training in the elderly. A scoping review was carried out, based on electronic searches in the Virtual Health Library (VHL), PubMed, SciELO and Google Scholar. 8 articles were selected. The results indicate that six of the selected articles dealt with acute effects and two articles investigated chronic effects of using different IRs. When analyzing the acute effects of different RIs, it is noted that shorter intervals promote a tendency for strength to decrease throughout the series, thus generating a smaller number of repetitions and consequently a lower training volume. In chronic studies, it was observed that the 1-minute RI was superior or generated the same responses compared to the longer RI (4 and 3 min). It is important to highlight that in the studies analyzed, the exercises were not carried out until muscle failure in all series, which may have mitigated the effect of fatigue during the series and promoted the maintenance of training volume. It was not possible to reach an absolute conclusion since acute studies with RI of 2 to 3 minutes promote greater volume, while chronic research indicates that RI of 1 minute is enough for the same or even better results compared to RI of 4 minutes and 3min, as long as the volume is equalized. Taking these results into account, it is suggested that eight weeks of training with a 1-minute interval can be a strategy to optimize training time, and consequently facilitate adherence or maintenance of training in the elderly.
