Abstract: Strength exercise can suscitation the endogenous anti-damage ability, and it is the effect meaure to protect ischemia heart. Suitable strength training can obtain the cardiol prconditioning protective effect, provid a new chance to clinical application for IPC, and have favourable prospect.But strength training may induce myocardic ischemia and ischemical reperfusion injury because of high exercise intensity, there are still many questions need to be solved. The artide focused on the cellule and molecule character of myocardic ischemia and ischemical reperfu-sion injury induced by strength training, the essential feature of strength training preconditioning and the signal transduction mechanism and the intra-cellular effector of myocardial preservation, proposing the research strategy, concrescencing the theory of contemporary strength training, clarifying some hot questions and important future di-rections on endogenous myocardial protection of strength training.
