Abstract:
To obtain a viewpoint concerning evaluation of endurance type of athletes, we investigated the difference in physiological responses between middle- and long-distance runners in an incremental running test. Measurements were VO2max and time of its appearance, change of VO2 from 1.5 min before exhaustion to exhaustion (ΔVO2), heart rate (HR), and blood lactate after exhaustion.
Results were as follows.
(1) The time of VO2 max appearance in the middle distance runners was earlier than in the long distance runners.
(2) VO2max was significantly higher in the long distance runners than in the middle distance runners.
(3) Blood lactate after exhaustion and HRmax were significantly higher in the middle distance runners than in the long distance runners.
(4) Blood lactate after exhaustion was significantly related to ΔVO2 (r =-0.660, P<0.05) .
These findings suggest that the endurance type of athletes could be evaluated from the time of VO2max appearance, blood lactate after exhaustion and HRmax in incremental running, and that VO2max appearance may be effected by high blood lactate accumulation.
