Purpose: The purpose of this study was to evaluate inter-machine reliability of the Velotron electromagnetically-braked cycle ergometer for the Wingate anaerobic test (WAnT) with power-trained athletes. Methods: Anaerobic athletes participating in football or track and field at a National Collegiate Athletics Association Division I program were recruited for participation in the study. Each participant visited the laboratory 3 times (1 familiarization trial, 2 experimental trials) within 2 weeks and at least 24 hours between visits. Participants completed a “practice trial” on the first visit to familiarize themselves with the 30-second WAnT. The WAnT procedure included a 5-minute warmup at a resistance of 75 W and a cadence of 60-100 rpms followed by a 3-minute rest before the test start. WAnTs were performed with a traditional flying start in which participants had 6 seconds of acceleration before a load of 8.5% of body mass was applied. Data of interest included mean power (MP), anaerobic capacity (AC), peak power (PP), anaerobic power (AP), and maximum revolutions per minute (RPMmax). Results: Results from a limited number of subjects suggested high reliability between Velotron ergometers. Peak power (1256.8±332.2W [Ergo A], 1234.6±344.0W [Ergo B]) and MP (770.2±154.9W [Ergo A], 807±120.0W [Ergo B]) did not differ substantially between trials. However, power outputs from testing trials were generally greater than from a familiarization trial. Conclusion: A familiarization trial is necessary for reliability testing. These preliminary findings also suggest that normative values can be established on different Velotron ergometers, and that tests completed on different Velotron ergometers are reliable.
