The effect of body position, configuration, and orientation on cycling performance

Experiment 1 was used to determine the effect of systematic manipulation of five body positions (seat tube angle) and configurations (hip angle) on cycling performance while controlling for body orientation (trunk angle with respect to the ground). Sixteen male subjects (21-35 years of age) were tested in each of five different body positions (0, 25, 50, 75, and 100 degrees) as defined by the angle formed between the seat tube and a vertical line. The seat backrest was kept perpendicular to the ground. It was determined from repeated measures MANOVAs, Dunnetts' multiple comparison tests and trend analysis that: (1) for total work output and maximal aerobic energy expenditure, performance in the 75 degree seat tube angle position (76.8 degree mean hip angle configuration) was significantly greater (p $<$.01) than all the other positions, except for the 50 degree seat tube angle (100 degree mean hip angle); and (2) a quadratic trend (p $<$.01) best describe the trend in total work output and maximal aerobic energy expenditure with changes in body position and configuration.
