| Total CK, U/L | 93.5 ± 8.1 | 111.9 ± 10.2a, p = 0.019 | 111.7 ± 10.2a, p = 0.004 | 92.4 ± 13.7 | 101.0 ± 14.1 | 109.3 ± 14.3a, p = 0.033 |

The exercise bout was performed indoors on a stationary bicycle for 30 min at intensity corresponding to 65–75% of maximum heart rate. Values are means ± SE; n = 19 per cohort. The p-values indicate the results of a Bonferroni post-hoc analysis. acompared with pre-exercise value (within group). hsCRP, high-sensitivity C-reactive protein; LDH, lactate dehydrogenase; CK, creatine kinase; CK-MB, creatine kinase-muscle and brain isoenzyme
