Physiologic and perceptual responses to exercise on a new cycle ergometer.

Abstract

This study observed oxygen consumption (VO2), heart rate (HR), and rating of perceived exertion (RPE) during both maximal and submaximal exercise tests on a conventional Monark cycle ergometer and a new Velodyne ergometer. The Velodyne uses the subject's own bicycle attached to an electrically braked roller, which regulates power output. Trained male cyclists performed maximal exercise tests on both ergometers (N = 7) and two submaximal tests on each of three identical Velodynes and a Monark (N = 6). VO2, HR and RPE were measured during the submaximal and maximal tests. Data were analyzed via multiple repeated-measures ANOVA. No differences were found across cycles during the maximal or submaximal tests. The results indicate that the Monark and the Velodyne ergometers elicited similar physiologic and perceptual responses and that the Velodyne can be a viable alternative to the conventional Monark ergometer.
