Abstract

This study investigated the cardiorespiratory responses to perceptually self-regulated shallow water exercise (SR-SWE) efforts. Females (26 ± 6 years) performed a series of SWE bouts prescribed at rating of perceived exertion (RPE) 9, 11, 13, 15, and 17 (Borg scale) and an incremental, SR-SWE bout to a max of RPE 20. Oxygen uptake (VO2) heart rate (HR), and blood lactate (BLa) were monitored. VO2, HR, and BLa ranged from 0.68 ± 0.13 l·min–1, 90 ± 16 bpm, 2.0 ± 0.7 mM (RPE 9) to 2.21 ± 0.21 l·min–1, 162 ± 11 bpm, and 3.9 ± 1.6 mM (RPE
