ABSTRACT
The objective of the present study was to analyze the influence of execution velocity on rating of perceived exertion (RPE) and on volume of repetitions at different velocities. Methods: The sample consisted of 10 male volunteers (23.4 ± 5.4 years old) with at least 6 months of experience in strength training. The participants performed 8 sets of up to 8 repetitions with an intensity of 60% of 1RM at different velocities of movement execution: slow cadence (6020), moderate cadence (2020) and free cadence. RPE (OMNI-RPE scale) and volume of repetitions performed in each condition were assessed. Results: The number of repetitions executed in the slow- and moderate-cadence protocols was smaller compared to that in the free protocol (p <0.05), as of the 2nd and 6th sets, respectively. RPE in the slow-cadence protocol was higher compared to that in the other cadences (p <0.05). Conclusion: The slow- and moderate-cadence protocols significantly reduce the number of repetitions performed and result in a greater rating of perceived exertion in comparison with free cadence.
