Influence of different speeds of muscle actions in the maximum dynamic strength, in the maximum volume of repetitions, and rated perceived exertion

Abstract

The purpose of this study was to investigate the influence of different speeds of muscle action on the maximum volume of repetitions (MVR), rated perceived exertion (RPE), and maximum dynamic muscle strength of 9 women. At the end of 3 series of each execution, protocol was added the MVR, and collected the RPE, the maximum dynamic strength was assessed 72 hrs after each protocol. The results showed no statistically significant differences in RPE, maximum number of repetitions, and maximum dynamic strength among the three protocols: concentric protocol (CP); eccentric protocol (EP); and control protocol (CoP). This study does not support the earlier observations of a decrease in the maximal contraction strength with eccentric protocols. Also, in regards to RPE, there were no statistically significant differences at the end of the execution of the 3 sets in the three different protocols analyzed.
