Physical training has been advocated to minimize the problems associated with coronary heart disease; however, the responsible mechanisms are obscure. Rats trained to run on a treadmill were subjected to acute conditions of hypoxia and myocardial ischaemia. Trained rats were better able to maintain a higher level of cardiac performance (dP/dt max) after hypoxia than non-trained rats, but no advantages were apparent after ischaemia. Biochemical data showed no myocardial differences between the groups in oxygen utilization or energy availability.
体育锻炼已被提倡用于尽量减少与冠心病相关的问题；然而，其相关机制尚不清楚。训练在跑步机上跑步的大鼠经受急性缺氧和心肌缺血状况。与未训练的大鼠相比，训练后的大鼠在缺氧后能更好地维持较高水平的心脏功能（最大dp/dt），但在缺血后未表现出优势。生化数据显示两组在氧利用或能量供应方面心肌无差异。
