Exercise cardioprotection against stunning may be MnSOD-independent in rats; leaves open distinct mechanisms versus infarction and precludes clinical translation.
Does endurance exercise improve postischemic recovery of cardiac external work independently of MnSOD in adult male rats?
Exercise-induced cardioprotection against myocardial stunning does not require an increase in cardiac MnSOD activity, indicating different mechanisms mediate protection against stunning versus infarction.
Lennon et al. (2004) studied this question.
