Impact of Instructor Cues on Changes in Cycling Form during a Spin Class

The purpose of this study was to examine the impact of instructor cues on joint angle changes and rating of perceived exertion (RPE) during a spin class. Fifteen participants (8M, 7F) of various cycling backgrounds participated with mean (+ or - SD) age, height, and weight of 22.6 + or - 5.07 yr., 1.73 + or - 0.10 m, and 66.94 + or - 12.03 kg, respectively. Informed consent was obtained and reflective markers placed on the right and left sides of the body over anatomical landmarks aligned with lower and upper limb joint centers. The MANOVA revealed a significant change in the group of variables throughout the course of the spin class (F = 843.52, p < .001). The overall measures of interest were not influenced by instructor cues (F = 0.00, p = .99). Significant joint angle changes were found at the hip (F = 7.30, p = .02) and left shoulder (F = 7.40, p = .02).
