PURPOSE Three to five consecutive days of endurance exercise can protect the heart against an ischemia-reperfusion (IR) insult. However, the mechanisms responsible for this exercise-mediated cardioprotection remain unknown. Given the important role that mitochondria play in IR-induced cardiac myocyte injury, we hypothesized that exercise training promotes cardioprotection, at least in part, by increasing mitochondrial antioxidants, preventing mitochondrial release of reactive oxygen species… CONTINUE READING
