Use of verbal command in the prescription of interval exercise for active women
Abstract
Interval exercise has become popular in recent decades, becoming an effective strategy for improving physical conditioning for untrained people and non-athletes. The aim of the present study was to verify whether there is a difference in the rating of perceived exertion (RPE) and running speed of interval exercise prescribed by verbal commands. 10 active women participated in the study. Three exercise sessions were performed based on the following verbal commands: light intensity, moderate intensity, and high intensity. Each exercise session consisted of 20 minutes of interval running (60s: 60s) in a back-and-forth format. RPE and speed (Km.h) were measured in each exercise session. Differences among verbal commands were observed for RPE χ2 (2) = 19.53 p < 0.001 and running speed χ2 (2) = 20.00, p < 0.001. The light verbal command was lower when compared to moderate and high, and the moderate verbal command was lower when compared to high for both RPE and running speed p < 0.01. The results of the present study suggest that different verbal commands can be used in the prescription of interval exercise for active women, and that moderate and high intensity verbal commands can provide adequate cardiorespiratory stimuli for significant changes in physical fitness.
