AbstractAn exercise test was devised to investigate the relationship between power and endurance for treadmill running. The subjects were 19 males aged 21-25 yr (11 distance runners and 4 sprinters of provincial grade, and 4 non-competitive runners). Each subject ran to exhaustion on a treadmill at 15kmhr−1at five different inclinations (31%-9%), giving maximum performance times in the range 10s to 3 min. An iterative least-squares procedure was used to fit the following exponential model to each subject's data: I1= I∞+ (I0−I∞)exp(−t/τ) where I1, I0and 1∞are inclinations at time t = t, t = 0 and t → ∞, and τ is a time constant. The fit was excellent (r 2= 0.96− 1.00). I0and 1∞are interpreted as measures of maximum anaerobic (instantaneous) and maximum aerobic (continuous) power respectively. Inclinations corresponding to performance times of 10-180s (I10−I180) were calculated from these parameters. Test-retest reliability was highest for I0-I30(intraclass r= 0.97−0.94), lower for I60-I∞(r= 0.89−0.84), and lowest for τ (r= 0.78). Good correlations were observed between I0-I30and peak power in a 30s all-out test on a cycle ergometer (r= 0.73−0.81), and between I180, I∞and maximum oxygen consumption (r= 0.87, 0.81). The test may be useful for ranking or monitoring running performance for events of up to 1 min duration.
