With increasing age, there is a change in the mitochondrial pattern of muscle tissue which leads to a loss of compliance of the arterial vessel wall and therefore to a slight change in contraction mode of the heart and also to a decrease of stroke and circulation volume. In the same way, lung function parameters such as vital capacity and forced ventilatory capacity are changes in the elderly. In addition to these, a higher incidence of general disease will change the organism, particularly heart circulation and the pulmonary system. In order to judge physical performance and sporting activity, certain physiological and pathophysiological features of aging have to be taken into consideration in the elderly. Avoiding any risks should be always above to intention of gaining a better physical condition, although this is desirable in principle.
随着年龄的增长，肌肉组织的线粒体模式会发生变化，这会导致动脉血管壁顺应性降低，进而使心脏收缩模式略有改变，同时也会导致中风和循环血量减少。同样，老年人的肺活量和用力通气量等肺功能参数也会发生变化。除此之外，全身性疾病的较高发病率会改变机体，尤其是心脏循环和肺部系统。为了评估身体机能和体育活动，老年人必须考虑衰老的某些生理和病理生理特征。尽管原则上改善身体状况是可取的，但避免任何风险应始终高于此目标。
