  1. Post-pre represents the change value between pre-intervention and post-intervention measurements. The reported LF and HF values represent 24-h averages.
  2. AE, aerobic exercise; HF, high frequency; LF, low frequency; LF/HF, low frequency to high frequency ratio; pre, before intervention; post, after intervention; TC, Tai Chi group.
  3. ** p < 0.01. * p < 0.05.
