Abstract

The study compared the effects of cycling at three different cadences and three different workloads on a stationary upright and stationary recumbent bicycle on the following variables: (a) heart rate, (b) heart rate as a percentage of maximum heart rate, (c) relative VO2, (d) relative VO2 as a percentage of VO2 max, (e) absolute energy cost, (f) RPE legs, and (g) RPE overall. Heart rate, relative VO2, R values, and RPE were measured as 18 subjects completed 18 experimental conditions in random order. The experimental conditions consisted of cycling on the stationary upright bicycle (Lifecycle® 9500) and stationary recumbent bicycle (Lifecycle® 9500R) at three pedaling frequencies--60, 70, and 90 rpm, and three workloads--65, 89, and 121 watts. A 3 x 3 x 2 repeated measures ANOVA analysis revealed physiological and perceptual variables increased significantly (p≤.05) as cadence was increased. Additionally, a significant first order interaction effect occurred for all physiological and perceptual variables for resistance by bike. At 65 watts, physiological and perceptual responses were greater on the upright bike. At 89 watts and 121 watts, physiological and perceptual variables were greater on the recumbent bicycle.
