  1. 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
