duration and vigour of physical exercise are widely
considered to be critical elements that may positively or negatively affect
physical health and immune response.
investigate the effect of a 12 week programme of
regular tai chi chuan exercise (TCC) on functional mobility, beliefs about
benefits of exercise on physical and psychological health, and immune
regulation in middle aged volunteers.
This quasi‐experimental research design involving one group with
testing before and after the programme was conducted
to measure the effect of 12 weeks of TCC exercise in 14 men and 23 women from
the normal community.
exercise had a highly significant positive effect on functional mobility (p = 0.001) and beliefs about the health
benefits of exercise (p = 0.013) in the 37 participants.
Total white blood cell and red blood cell count did not change significantly,
but a highly significant (p<0.001) decrease in monocyte
count occurred. A significant (p = 0.05) increase in the ratio of T
helper to suppressor cells (CD4:CD8) was found, along with a significant (p = 0.015) increase in CD4CD25
regulatory T cells. Production of the regulatory T cell mediators transforming
growth factor β and interleukin 10 under specific antigen stimulation (varicella zoster virus) was also significantly increased
after this exercise programme.
A 12 week programme of regular TCC exercise enhances functional
mobility, personal health expectations, and regulatory T cell function.
