Description

The cycling 3-min all-out exercise test (3 MT) has been established to provide measures of critical power (CP) and one’s anaerobic capacity (W’). The biking 3 MT have been completed using an electronically brake cycle ergometer. To evaluate if it is possible to conduct a 3 MT using a computrainer. We evaluated a group of competitive cyclists and triathletes (age 23.5 ± 1.64 yrs, VO2max 53.6 ±7.14 ml∙kg-1∙min-1). Each athlete completed a 3 MT, one 3 min, 6 min and 9 min exhaustive bout using their own bike mounted on a computrainer (Race mate). Predicted power for 3, 6, and 9 min were determined using the CP and W’ estimated from the 3 MT. Actual and predicted times were evaluated using typical error (TE) and coefficient of variation (CV). For the 3 min bout, TE was 41 s and CV was 24.9%. For the 6 min bout, TE was 62 s and a CV was 20.3%. For the 9 min bout, TE was 79 s and CV was 17%. A more complete data set will be forth coming. Thus far it appears that the 3 MT using a computrainer is underestimating CP.
