为了研究体育锻炼在多大程度上影响肌肉力量和肌肉成分的年龄相关变化，研究人员对12名70岁男性进行了为期12周的动态和静态运动训练，每周三次，每次45分钟。研究对象无心血管和运动症状。训练后有氧能力增加，在所有测量角速度下的静态和动态肌肉力量显著增加。在对照组中，这些变化都没有出现。训练后的纤维成分显示II型纤维的比例显著提高。训练适应的酶学证据是肌肉肌激酶和乳酸脱氢酶的显著增加。结果表明，70岁男性的有氧能力和肌肉力量是可以训练的。
In order to investigate to what extent physical training might influence age-related changes in muscle strength and muscle composition, 12 70-year-old men were trained for 45 minutes three times a week for 12 weeks with dynamic and static exercise. The subjects in the study were free of cardiovascular and locomotor symptoms. After training the aerobic capacity was increased and static and dynamic muscle strength at all measured angular velocities increased significantly. In the control group none of these changes was seen. The fibre composition showed a significantly higher proportion of Type II fibres after training. Enzymatic evidence of training adaptation was found with significant increments in enzymes as muscle myokinase and lactate dehydrogenase. The results have shown that aerobic capacity and muscle strength are trainable in 70-year-old men.
