An evaluation of tests of anaerobic power.

The objectives of this study were to examine the relationships between two recently developed laboratory tests of anaerobic power (AnP) and to compare these tests to other measures of AnP. Fifteen male subjects, aged 20-34 years, performed: a 30-s maximal cycle ergometer test (Wingate test), a 60-s isokinetic knee extension test (isokinetic endurance test), a 50-m sprint, a 200-m sprint, and the Margaria stair-climb test. Significant correlations ranging from 0.52-0.76 were found between the Wingate and isokinetic endurance tests for peak and mean values of power and torque, respectively. Indices from both these tests also correlated significantly with the other tests of AnP. The best single index was mean power from the Wingate test, which had correlations of -0.79, -0.82, and 0.74 with the 50-m and 200-m sprint times and the Margaria test, respectively. The data suggest that both the Wingate and isokinetic endurance tests represent valid laboratory tests for evaluating high-intensity, short-term exercise in which the muscle is primarily dependent upon anaerobic processes for energy release.
