Wingate Power Output Testing on a Recumbent Ergometer

The Wingate anaerobic power output test was developed to assess the power output of the muscles called on during a short, maximal anaerobic cycling bout of 30-second duration. This test has traditionally been administered using an upright mechanical cycle ergometer. No known evidence exists in the available literature that the Wingate test has been reliably administered using a recumbent ergometer, an exercise modality experiencing increased popularity for both conditioning and rehabilitation, particularly in aging and disabled populations. This study was designed to compare test-retest measures of peak power output (PPO), mean power output (MPO), and fatigue rate (FR) on electrically braked upright and recumbent cycle ergometers preprogrammed for the 30-second Wingate test protocol. Twenty-three college-aged men (n = 9) and women (n = 14) volunteered for the study. Each subject performed 2 trials on the upright ergometer and 2 trials on the recumbent ergometer with at least 1 day of rest between trials. Trials were randomized over a 2-week period. Resistance was set at 0.075 kg per kilogram of body weight. No significant differences were found between the upright or recumbent ergometers for all 3 variables in men (p > 0.05). Significant intraclass correlations were found between the mean of the upright and recumbent trials for PPO (r = 0.96), MPO (r = 0.99), and FR (r = 0.68). Significant differences were found between upright and recumbent ergometers for PPO and FR, but not in MPO for women (p > 0.05). Significant intraclass correlations were found between the mean of the upright and recumbent trials for PPO (r = 0.98), MPO (r = 0.97), and FR (r = 0.81). The results of this study support the recumbent ergometer as a valid and reliable instrument for measuring PPO, MPO, and FR in men, when compared with an upright cycle ergometer using the Wingate test.
