Short-term exercise may protect rat myocardium from I/R independent of HSPs; hypothesis-generating for alternative mechanisms and leaves clinical translation open.
Does short-term exercise improve myocardial tolerance to ischemia-reperfusion injury in rats?
Short-term exercise provides myocardial protection against ischemia-reperfusion injury independent of heat shock protein elevation, potentially through increased antioxidant defenses.
Hamilton et al. (2001) studied this question.
