Thai Yoga as an Appropriate Alternative Physical Activity for Older Adults

Abstract

Thai Yoga (TY), has been recommended by the Public Health Ministry of Thailand for keeping people fit. There is little known about the physiological demand it places on those practicing it. Therefore, the purpose of this study is to determine i) the exercise intensity of TY indicating by both absolute intensity (i.e. MET) and relative intensity (i.e. percentage of maximal oxygen consumption (VO2,max) and heart rate (HRmax)) and ii) the impact it has on the cardiovascular system and energy expenditure. Fourteen healthy adults ranging in age from 50 to 65 years performed 30-minute TY and exhaustive cycling exercise (to indicate maximal oxygen consumption) sessions one week apart. Mean of MET and the percentage of mean of VO2 and HR during TY to VO2,max and HRmax were found to be 1.51±0.43 METs, 35.5+/-11.9 ml/kg/min and 50.0+/-8.6 /min, respectively. The decreased HR was observed from baseline to warm up and the peak rates of energy were found to be expended in the standing posture. Results indicate that TY may be considered a very light- to light-intensity exercise. Performing longer duration in standing posture may improve cardiovascular fitness for older adults. Moreover, the relaxation component during warm up may improve psychological well-being.
