This presentation addressed the researches concerning the effects of the low intensity training on health promotion done in our laboratory. Supervised physical training performed at 50 % to, max or lactate threshold for 60 minutes, 3 or 5 times a week for 30 sessions could induce the improvement in to, max, Iipid profiles, and augment in cardio-pulmonary barore-flex. This training was also applied for patients in ischemic heart disease, hypertension, and obesity. These patients could improve their aerobic work capacity. Hypertensive patients could reduce their blood pressure in association with modulating in humoral factors without changes in body weight and diet. The obese patients succeeded in significant body reduction with mild food reduction. We also found the existence of break-point of double product (BPDP) during graded exercise test corresponding to lactate threshold. BPDP will be able to use for estimating lactate threshold. This low intensity training, which is easier and safer, can be recommended to the wide-variety of persons including older person to promote health.
