Eighteen male subjects, aged 20 to 28 years, engaged in three fatigue bouts using an isokinetic dynamometer to measure knee extension contractions. Peak torque varied inversely with movement speed, and the pattern of decrement was independent of speed. Time to peak torque did not change significantly across trials in isokinetic fatigue. (Author/MT)

Greater control of the muscular fatigue process is afforded by regulation of energy expenditure through monitoring the rate of contraction rather than by varying the duration of contraction. (Author)

The pattern of fatigue resulting from systematically varying the intercontraction rest interval was examined in male and female subjects employing a hand-grip fatigue exercise. Results and conclusions are presented. (Author/MT)
