    摘要: The purpose of this study was to determine the predictability of critical velocity (CV) upon endurance running potential via the investigation of the effect of blood lactate during 20-min running of the distance runners. The raw data of the distance runners used were 20 males (age 25.65±8.12yr, weight 60.53±7.92kg, height171.35±6.61cm, VO2max 63.55±8.03ml•kg(superscript -1)•min(superscript -1),VT 49.45±8.78ml•kg(superscript -1)•min(superscript -1).The principle of the relationship between running time and distance was used to calculate CV. The CV of every subject was calculated through his best records of 800m, 1500m and 5000m running. All subjects participated all of the three 20-min exercise tests on treadmill, with the speed 85% CV, 100%CV and 115%CV respectively. The concentration of blood lactate was measured before and after each of the three test. The results were as follows:1)CV and the average velocity of the best records of 800m, 1500m and 5000m running (2.24±0.15,4.65±0.29 and 17.71±1.06min, individually) all were significantly correlated (0.51,0.54 and 0.99). Furthermore, the correlation between the average velocity of 5000mrunning, VO2 max and AT were 0.57(p＜.05)and 0.66(p＜.05).2)When running on85% CV and 100%CV,all subjects finished running for 20-min, but running on 115% CV, the running time was 9.13±3.26 min only.3).The concentration of blood lactate collected after the three tests was significantly different with each other (2.32±0.86,6.93±3.47 and 11.38±2.49 mM/L)for the distance runners. In conclusion, the higher the CV, the better the endurance running potential for the distance runners. However theoretical CV overestimates the practical running velocity that could maintain blood lactate on a stable condition by about 15%.
