Abstract

The Wingate test has been used as a major test of muscle power whereas isokinetic devices have been used to determine muscle strength. The aim of this study was to examine the relationships between the 30 s Wingate test and tests using repeated knee extensions/flexions on an isokinetic dynamometer (Akron). Ten females and eight males undertook a 30 s Wingate test, six maximal reciprocal contractions of the knee extensors and flexors in the isokinetic dynamometer, and a 30 s test of repeated maximal reciprocal contractions of the knee extensors and flexors. Five minutes after the 30 s tests a blood sample was taken for lactate determination. Significant correlations were obtained for the peak power output (PPO) between the Wingate test and the isokinetic extension and flexion tests. Significant correlations were also obtained for the fatigue index (FI) between the Wingate test and the 30 s isokinetic test. Fatigue index was defined as the decline in PPO over time. Values for PPO were significantly higher in the Wingate test than the corresponding extension and flexion values in the isokinetic maximum torque test. Post-exercise blood lactate concentrations were also significantly higher for the Wingate test than for the 30 s isokinetic test. There was a weak but significant correlation between blood lactate for the Wingate and 30 s isokinetic test. These results suggest that the isokinetic tests used in this study are useful measures of anaerobic power. Verf.-Referat
