another influential factor. The anaerobic energy systems use glucose as the primary energy source, and greater available glucose could influence the power output over short intervals. Therefore, glucose consumption prior to testing should be standardized between all participants. Sampling rate can severely impact the values obtained for peak and average power output. Sampling rates consistent with a standard mechanical ergometer test show significantly lower peak and average power values than a test with much higher sampling rates in the computer data feeds. Furthermore, tests that use low sampling rates (< 2 Hz) tend to be less consistent than tests with high sampling rates. This suggests that a sampling rate of at least 5 Hz (0.2 sec) provides the most accurate results. Other Uses The Wingate test can also be used in training instances, especially in cyclists. In many races, cyclists finish the race with a sprint. This maximal exertion stresses anaerobic energy pathways. As Hazell et al. have demonstrated, training in this manner can increase aerobic and anaerobic performance. Since this method can increase anaerobic performance, many cycling athletes have taken to using repeated sprint intervals, such as the Wingate test, as training devices to increase performance in the final leg of the race. These Wingate tests may be slightly modified version of the standard test laid out above. See also Anaerobic training High-intensity interval training References Exercise physiology Fitness tests
