One of the most important aspects of high performance cycling is the best fit between rider and bike. Developing a proper bike fit requires conducting many biomechanical assessments due to the need to match a myriad of bike geometries and human anthropometric variables. One of the primary bike-rider system measurement parameters for power and pedal efficiencies is the cleat placement and alignment. The purpose of this study was to examine the effects of moving the cleats towards the heel on peak power outputs and pedal efficiencies using a Computrainer (CT) and 2D video analysis. Ten competitive male cyclists participated in the study consisting of tests for peak power (PP) outputs and pedaling efficiencies among two positions of cleats; toe (TP) and heel (HP). No significant differences in peak power outputs were reported between TP and HP (p = .827). Significant differences (p = .027) did exist, however between each condition within the SpinScan (SS) pedal efficiency test. Results from the 2-D video analysis indicate that there exists a difference in ankling patterns between the TP and HP during the first 50 percent of the power phase and the last 50 percent of the recovery phase of the pedal stroke (p = .000 and .001 respectively Based on the results of this study, further research into the longitudinal effects of training in this area are warranted. / School of Physical Education, Sport, and Exercise Science
