The present study compared the results of average anaerobic power production (MP), peak power (PP), and fatigue percent (FP) between physically active women (those participating in aerobic classes 3 to 5 days a week) from 2 age groups: Group 1, ages 18 to 29 (n = 32); Group 2, ages 30 to 42 (n = 23). It was hypothesized that there would be significant differences in MP, PP, and FP intermediate-term anaerobic parameters between age groups on the Wingate bicycle ergometer test. Anaerobic power indices between groups were not significantly different when analyzed separately (p < 0.05), but there was a significant difference between groups on measures of FP It was concluded that average and peak anaerobic power neither declines nor increases over time with fit women who participate in aerobic activities. The significantly different FP results between groups indicate that frequent aerobic activity helps delay the onset of anaerobic fatigue, as evidenced by a lower FP in the older group.
