Abstract:
The purpose of this study is to discuss the effects of aging and exercise on aerobic capacity in the elderly and the procedure for encouraging sedentary elderly to engage in a health promotion program based on aerobic exercise. Regular proper aerobic exercise training, even when started as an elder, induces an increase in maximal oxygen intake and lactate threshold (or ventilatory threshold) by enhancing ventricular diastolic function and oxidative capacity in muscle ; and reduces the risk factors of lifestyle related diseases. There was a need for a simple test for determining aerobic capacity and exercise prescriptions in community-dwelling elderly. We recommended two methods for this purpose : one is to determine DPBP and the other is to estimate work rate at a certain concentration (rest plus 0.1 mmol /l ) of the blood lactate based on it just after 2 A stage step exercise. Both work rate can be used not only for evaluation of the aerobic fitness level, but also a safer and effective exercise intensity to elucidate the benefit of aerobic exercise. These tests were very simple and can determine 5 to 10 people simultaneously.
