Table 3 shows the differences of the outcome measures on
the TA between the intragroup and intergroup. The TA was
significantly increased in the Tai Chi group from
23.75 ± 3.78 u/mmol at pre-intervention to 26.31 ± 2.93 u/
mmol after six months (p < 0.05). In the control group, the TA
insignificantly changed after six months. The intervention
group and control group exhibited a significant difference on
TA after six months (p < 0.05), but an insignificant difference
existed between them at pre-intervention.
