Perceptual Responses to Deep Water Running and Treadmill Exercise

Abstract

Perceived exertion during deep water running and treadmill exercise was measured to examine gender and mode-specific responses. Deep water running to VO2 peak was performed in 3-min. stages at leg speeds controlled by a metronome. Treadmill exercise was performed at matched leg speeds. VO2 and heart rate were continuously monitored by open circuit spirometry and radiotelemetry. Perceived exertion was measured using Borg's 6–20 point scale. Statistical analyses were performed using multiple linear regression with dummy coded discrete variables. Ratings of perceived exertion were significantly higher during deep water running when exercising at equal leg speeds. Mean rated perceived exertion at each stage of the test for either exercise mode was not significantly different between men and women.
