Abstract

OBJECTIVE:

Observe the improvement effect of different cycles of Tai Chi exercise on the senile respiratory and cardiovascular circulatory function.

METHODS:

Select 180 elderly men who don't usually do the fitness exercise and then ask them to do Tai Chi exercise. Test their related indicators respectively prior to exercise and upon exercise for 3 months, 6 months and 12 months. ① The cardiac pump function indicator: "Stroke Volume", "Ejection Fraction" and "Heart Rate"; ② Rheoencephalogram (REG) indicator: "Inflow time", "Wave Amplitude"; ③ Pulmonary ventilation indicator: "Vital Capacity" (VC), "Maximum Minute Ventilation" (MMV).

RESULTS:

① Compared with the indicators before exercise, each indicator has no significant difference after 3 months of exercise and a part of indicators are improved after 6 months of exercise, but most indicators have no significant differences; ② After 12 months of the exercise, compared with those indicators before exercise, the tested indicators are obviously improved. Specific data indicates that stroke volume (mL) is increased to 71.82 ± 10.93 from 66.21 ± 11.35 and the ejection fraction (%) is improved to 67.89 ± 4.94 from 60.54 ± 5.02, but the heart rate (times/min) is reduced to 67.15 ± 8.39 from 76.62 ± 8.40, mean P<0.05; inflow time (s) is shortened to 0.13 ± 0.04 from 0.17 ± 0.05; the amplitude (Ω) is increased to 1.19 ± 0.23 from 0.97 ± 0.21 before exercise and mean P<0.05; the vital capacity (L) is increased to 3.57 ± 1.39 from 2.84 ± 0.32; maximum minute ventilation (L/min) is improved to 117.25 ± 14.86 from 97.26 ± 14.71, mean P<0.05.

CONCLUSION:

The short-term Tai Chi exercise that is less than six months the following 6 months has no significant effect on the senile respiratory and cardiovascular circulatory function, however, with the longer exercise duration, after 12 months' exercise, it can significantly improve the effect.
