The purpose of this study was to examine the effect of Healthtron^【○!R】 on recovery after exercise. Seven subjects, three men and four women with averaging 22.1 yrs. of age, performed three cycling exercise tests at 60% VO_<2max> for 15 minutes. After exercise, subjects engaged in three recovery conditions for 30 minutes. These recovery conditions consisted of sitting rest (SR), sitting on Healthtron (HT), followed five-minute cycling (0W) and sitting rest (light exercise : LE). Heart rate and blood lactate concentration were measured before the exercise test, immediately after, and 5, 10, 20, and 30 minutes after exercise. Heart rate increased (p<0.05) due to the exercise and returned to the pre-exercise level five minutes after exercise during each recovery condition. Blood lactate concentration (La) increased (p<0.05) with exercise in each recovery condition. After five-minute exercise, La returned to the pre-exercise level in HT and LE, but not in SR. The rate of La decrease after exercise in HT was larger than those in LE and SR, and all the subjects in HT showed a similar decreasing trend along with 30-minute recovery. These results lead to the conclusion that Healthtron promotes effective removal of blood lactic acid after moderately intense exercise.
