This was achieved via two methods: (1) matching females of low and moderate aerobic fitness ( $$\dot{V}\hbox{O}_{2\max}$$ : 36.4±4.7 vs 49.6±5.5mlkg−1min−1 ; p<0.05) for initial sprint performance and then comparing RSA, and (2) semi-partial correlations to adjust for the influence of initial sprint performance on RSA. Tests consisted of a RSA cycle test (5×6-s max sprints every 30s) and a $$\dot{V}\hbox{O}_{2\max}$$ test. Muscle biopsies were taken before and after the RSA test. There was no significant difference between groups for work (W 1, 3.44±0.57 vs 3.58±0.49kJ; p=0.59) or power (P 1, 788.1±99.2 vs 835.2±127.2W; p=0.66) on the first sprint, or for total work (W tot, 15.2±2.2 vs 16.6±2.2kJ; p=0.25). However, the moderate $$\dot{V}\hbox{O}_{2\max}$$ group recorded a smaller work decrement across the five sprints (W dec, 11.1±2.5 vs 7.6±3.4%; p=0.045). There were no significant differences between the two groups for muscle buffer capacity, muscle lactate or pH at any time point. When a semi-partial correlation was performed, to control for the contribution of W 1 to W dec, the correlation between $$\dot{V}\hbox{O}_{2\max}$$ and W dec increased from r=−0.41 (p>0.05) to r=−0.50 (p<0.05). These results indicate that $$\dot{V}\hbox{O}_{2\max}$$ does contribute to performance during repeated-sprint efforts. However, the small variance in W dec explained by $$\dot{V}\hbox{O}_{2\max}$$ suggests that other factors also play a role.
