The purpose of this investigation was to determine the time course and magnitude of learning effects associated with repeated maximum cycling power tests and to determine if cycle-trained men exhibit different learning effects than active men who are not cycle-trained. Cycle-trained (N = 13) and active men (N = 35) performed short maximal cycling bouts 4 times per day for 4 consecutive days. Inertial load cycle ergometry was used to measure maximum power and pedaling rate at maximum power. Maximum power of the cycle-trained men did not differ across days or bouts. Maximum power of the active men increased 7 % within the first day and 7 % from the mean of day one to day three. Pedaling rate at maximum power did not differ across days or bouts in either the cycle-trained or active men. These results demonstrate that valid and reliable results for maximum cycling power can be obtained from cycle-trained men in a single day, whereas active men require at least 2 days of practice in order to produce valid and reliable values.
