Preferred Pedal Rate and Perceived Exertion in Recreationally Active Versus Trained Cyclists

Abstract

PURPOSE: To examine the relationship between preferred pedal rates and perceived exertion in recreationally active and trained cyclists. METHODS: Subjects were divided into two groups based on previous cycling experience. Seven subjects (mean age ± SD: 22.4 ± 1.8 yrs) made up the recreationally active cyclist group and seven subjects (mean age ± SD: 32.9 ± 7.8 yrs) made up the trained cyclist group. Subjects were tested for five minutes at three power outputs (100, 150, 200 W) and at four pedal rates (50, 70, 90 rpm, and preferred pedal rate). Preferred pedal rates were measured using an electro-magnetic stationary bicycle trainer attached to a performance road bicycle that was adjusted accordingly. Perceived exertion was measured using the OMNI-RPE Scale. RESULTS: For both groups, perceived exertion of preferred pedal rates were not found to be significantly lower than perceived exertion of non-preferred pedal rates (p >.05). Trained cyclists did prefer significantly higher pedal rates than recreationally active cyclists at all power outputs (p <.05). Trained cyclists also recorded significantly lower ratings of perceived exertion than recreationally active cyclists throughout most stages with the exceptions of 50 and 70 rpm at 100 W and 70 rpm at 150 W (p < 0.5). CONCLUSIONS: Perceived exertion is not a primary indicator of the selection of pedal rates during cycle exercise.
