The purpose of this study was to examine the relationship between anaerobic running capacity and peak plasma lactate. Twelve adult males (mean age +/- SD = 21.9 +/- 1.2 yrs) performed a critical velocity test from which anaerobic running capacity was determined and a maximal treadmill running test from which peak plasma lactate was determined from post-exercise blood samples taken at one minute intervals. The results indicated that anaerobic running capacity (mean +/- SD = 0.18 +/- 0.04 km) was not significantly (r = -0.06, p greater than 0.05) correlated with peak plasma lactate (9.3 +/- 1.8 mM). These findings do not support anaerobic running capacity as an indirect indicator of anaerobic capabilities.
