Influence of Taijiquan on NK cell and in the Elderly

The researchers paid attention to the mechanism of aging with advancing age. Exercise training is thought as one of the most effective means putting off the occurrence of aging, and many works has shown that regular moderate training may promote the immune function and reduce the blood viscosity in aged subjects.
There were fewer researches about the influence of Taijiquan on hemorrheology and immune function. The purpose of this study is to observe the effect of Taijiquan on interleukin-2 (IL-2) concentration.
Sixteen health women (ages 55-65yr) were assigned to exercise group(n=10) and control group(n=6). The subjects of exercise group practised Taijiquan of 24 style everyday from 6:00-7:00. The experiment lasted 6 months. The control group subjects didn't take part in any exercise except daily life.
There findings:
1) The resting NK cell number and IL-2 concentration were increased after six months .
2) There was great changes in NK cell number and IL-2 concentration before and after one hour Taijiquan exercise.
