Abstract: The purpose of the present study was to assess the relationship between anaerobic threshold values and performance times on the 5 km and 10 km distance races in female recreational runners. Anaerobic threshold (AT), VO2 max, and related measures were determined for 31 runners aged 18-35 who were running between 15-30 miles per week at the onset of the study. Physiological measures were determined by subjecting the runners to maximal and submaximal treadmill exercise. Determination of AT was based upon respiratory gas exchange and was defined as the departure from linearity of VEV02 without a corresponding increase in VEVO2. Mean AT-VO2 was 34.98 ml•kg•min -1 (1.978 1-min -1) while VO2 max averaged 45.42 ml•kg•min -1(2.556 1•min ). Mean percentage of AT-V02 was 78.8%. Average treadmill velocity at AT was 152.53 m/min. The correlations between VO2 max and 10 km and 5 km performances were significant (r = -.67 and -.58, respectively) while those between AT-V02 and running performances were not significant. However, when demographic characteristics of subjects were adjusted, treadmill velocity at AT and percentage of AT-V02 were the best predictors of 10 km performance. Treadmill velocity at AT alone was the best predictor of 5 km performance when the effects of physical variables were partialed out. It was concluded that additional physiological parameters should be considered when attempting to predict 5 km and 10 km performance times for female recreational runners.
