(a) Changes in visual analogue scale (VAS) scores for pain with respect to pre-eccentric exercise (Pre) values, (b) thigh circumference, and (c) range of knee motion (ROM), immediately after eccentric exercise (IPE) and 24 h, 48 h, and 72 h after eccentric exercise (mean ± 95% CI). Data were analyzed using a two-way repeated-measures ANOVA with post hoc Fisher’s Least Significant Difference (LSD) in comparison to from pre-eccentric exercise values. # = Significant difference in the placebo group in comparison to pre-eccentric exercise values (p < 0.05), * = Significant difference in the crocodile blood group in comparison to pre-eccentric exercise values (p < 0.05).
