Figure 2. Comparison of mean variations of pain scores of anterior thigh (A), posterior thigh (B) and calf (C) and calf pain score reduction (D) in Con group and O3 group of untrained males with overweight and obesity at before the HIIT, immediately (0h), 24 hours and 48 hours after the HIIT. The calf pain score reduction = (calf pain score at 24h - calf pain score at 48h)/calf pain score at 24 h). Values are mean ± SD. Two-way repeated measure ANOVA and Tukey’s post hoc test was used. * P < 0.05, ^a different from before HIIT, ^b different from 0h after HIIT, ^c different from 24h after HIIT.
