The purpose of this study was to investigate the effect of the moderate intermittent exercise ad a cool-down exercise after a intensive work on lactate disappearance. For this purpose, blood lactate disapperance rate during the moderate intermittent recovery exercise was compared with the continuous recovery exercise of same intensity, using a bicycle ergometer. After three bouts of maximal effort of 1-minute pedaling, all subjects (n=6) performed the following three different recovery treatments for 30 minutes: 1) rest, 2) continuous exercise of 40% VO_2 max, and 3) intermittent exercise consisted of 40% VO_2 max-works for 3 minutes and rest periods for 3 minutes in-between. Blood lactate concentration, heart-rate, gas exchange parameters (VO_2, VCO_2, VE, and R) were measured during recovery period. Blood lactate disappearance rate was significantly faster both in the continuous and the intermittent recovery exercise as compared with that in the resting recovery. The intermittent recovery exercise Was smaller in total work output and work time, and showed a lower heart-rate and VO_2 during exercise compared with the continuous recovery exercise. However, no significant difference between the two recovery exercises was observed in blood lactate concentrations during exercise. This result seems to suggest that the intermittent recovery exercise, consisting of moderate intensity of works and short-term rests, has the equal effect in acceleration of blood lactate disappearance to the continuous recovery exercise of same intensity.
