将经历过长期体力活动生活方式的老年男性(OA)的SRT、DRT和MT与不活跃的同龄男性(ONA)、活跃的(YA)和不活跃的年轻男性(YNA)进行比较。虽然活动水平和年龄是重要因素，但除DRT外，大多数活动水平与年龄的交互作用归因于ONAS的较慢表现。至少在这项研究中，与年龄相比，体力活动的生活方式似乎在决定SRT、DRT和MT方面起着更重要的作用。由于MT的结果与SRT和DRT的结果相似，因此认为老年人反应减慢的大部分原因是中枢神经系统的处理而不是MT的减少的假设被推翻。
The SRT, DRT, and MT of older men (OA) who have experienced a life style of chronic physical activity were compared to those of nonactive men of similar age (ONA), and also to active (YA) and nonactive young men (YNA). Although activity level and age were significant factors, most of the activity level-by-age interaction in all but DRT was attributed to the slower performance of the ONAs. At least in this study, a life style of physical activity appeared to play a more dominant role in determining SRT, DRT, and MT than age. The hypothesis that most of the slowing of responses in the aged is attributable to CNS processing rather than MT decrements is repudiated, since MT results paralleled those of SRT and DRT.
