Table 3 Comparison between pain score at baseline, post-exercise, and 24 h after

VAS of pain
% change in score, median (range)	Change between baseline and post-exercise				Change between baseline and 24-h post-exercise
% change in score, median (range)	Pre-exercise baseline	Post-exercise	95% CI	p value	Pre-exercise baseline	24-h post-exercise	95% CI	p value
20 (− 25, 33.3)	5.07 ± 1.16	5.20 ± 1.27	(− 0.53, 0.24)	0.44	5.07 ± 1.16	4.47 ± 1.30	(0.21, 1.07)	0.007

The intra-group variability is determined by t test. Significance level of p value is ≤ 0.05
