作者调查了指示生物老化和认知的感觉运动变量之间的关联。对202名年龄在60-86岁之间的女性进行了5项下肢力量、视觉对比敏感度（VisCS）和反应时间（RT）的评估。分层多元回归分析表明，感觉运动变量解释年龄相关的方差的措施BF推理和总方差的推理措施后，教育，健康，情绪和体力活动的控制。它的结论是，除了更好地了解认知老化的预测，如RT和VisCS，下肢力量是一个重要的预测性能的认知测试。
The authors investigated the association between sensorimotor variables indicative of biological aging and cognition. A community sample of 202 women ages 60-86 was assessed on 5 measures of lower limb strength, visual contrast sensitivity (VisCS), and reaction time (RT). Hierarchical multiple regression revealed that the sensorimotor variables explained age-related variance in measures bf reasoning and total variance in measures of reasoning after education, health, mood, and physical activity were controlled for. It is concluded that in addition to better known predictors of cognitive aging, such as RT and VisCS, lower limb strength is an important predictor of performance on cognitive tests.
