Abstract
The purpose of the present study was to investigate the effect of long-term Wai Tan Kung exercise on heart rate (HR), energy expenditure, oxygen uptake (VO2), ventilation (VE), heart rate variability and blood pressure. Two different groups of older adults were recruited. One group subjects (n =16; 65.0 ± 4.2 yrs, 163.3 ± 7.3 cm, 63.3 ± 7.3 kg) had been participated at least 10 years of regular Wai Tan Kung exercise (long-term group, LTG), and the other (n = 16; 59.0 ± 3.7 yrs, 162.0 ± 3.9 cm, 65.7 ± 3.6 kg) had been participated as same exercise as LTG but less than one year (short-term group, STG). The results of this study showed that there were significant differences (p < .05) in rest systolic pressure, and HR, energy expenditure, VO2, VE, high frequency power (HFP) and low frequency power (LFP) during exercise between LTG and STG (p < .05). LTG subjects had a significant lower in rest heart rate and blood pressure (p < .05) than STG subjects, and the former also reached higher (p < .05) exercise intensities during exercise testing than the latter. Moreover, there were significant higher heart rate, VO2 and VE during exercise testing for LTG than STG, suggesting that LTG subjects had higher metabolic rate. Additionally, LTG had a higher HFP than STG, suggesting that there was a significant increase in parasympathetic division of autonomic nervous activity during exercise testing for LTG than STG, indicating LTG subjects may prevent from coronary artery disease and improve functions of the heart. It is concluded that older adults participate in regular long-term of Wai Tan Kung exercise have a positive effect on their cardiovascular fitness. Therefore, such kind of exercise may especially fit for older adults.
Key words: oxygen uptake (VO2), ventilation (VE), heart rate, heart rate variability, Wai Tan Kung exercise.
