* = p < 0.05 (comparison between group).
Control = control group, Moxi = moxibustion group. Mixed-methods analysis was the global test indicating differences within and between groups. Post hoc testing was performed with unpaired t tests by comparing change since baseline between groups. immediate = immediately after DOMS induction, per- = per-treatment, post- = post-treatment, 24 = 24 hours after DOMS induction, 48 = 48 hours after DOMS induction, 72 = 72 hours after DOMS induction, Pain VAS =Pain Visual Analog Scale, MIMS= maximum isometric muscle strength. ANOVA =Analysis of Variance.
