inflammation or infections [20,44]. The TA and GT were not
assessed during Tai Chi training. Therefore, given the unknown
reaction time for changing TA and GT, up-regulated TA
and GT might be challenged. The association of Tai Chi exercise,
TA, and GT observed in this study should be cautious
because of the aformentioned limitations. Although this study
has limitations, it provides the possibility of TA as an important
biomarker for aging interventions.
