Physical training, from the type of modifications which it causes in the body, exclusively concerns patients suffering from coronary disease. Because of the decrease of the double product, there is an increase of the ischemic threshold on exertion, with decrease in the number of angina pectoris attacks and of the shift of the ST segment during the stress test. Training must be based on physical exercises in endurance (jogging, bicycle) at the rate of 3 weekly sessions to reach a good level of intensity corresponding at least to an energy consumption of 2,000 calories per week. Training must be continued indefinitely, which makes if a difficult therapy to prescribe and observe.
体育锻炼，就其在身体上引起的改变类型而言，仅适用于冠心病患者。由于双乘积降低，运动时缺血阈值增加，心绞痛发作次数减少，应激试验期间ST段移位减少。训练必须基于耐力体育锻炼（慢跑、骑自行车），每周进行3次，以达到至少相当于每周消耗2000卡路里能量的良好强度水平。训练必须无限期持续，这使得它成为一种难以规定和遵守的治疗方法。
