这项研究评估了一项为期三年的运动计划对运动表现和认知处理速度的影响，这些运动计划的对象是年龄在57-85岁之间、以前久坐不动的老年妇女。测试的变量包括简单和选择反应时间（CRT）、平衡、坐下和到达灵活性、肩部灵活性和握力。研究对象每周参加三次符合美国运动医学学院指导方针的运动表现课程。结果表明，在研究过程中，所有指标的表现都有显着改善(p <。0.01)，除了sit and reach test (SRT)，其中显著性接近(p小于。[00:27]，但没有达成。运动受试者与非运动对照组的比较显示，除了CRT和握力外，治疗和时间在所有变量上都有显著的相互作用。在三年的时间里，运动组的测试前和测试后得分有提高的趋势，而对照组的得分则有所下降。反应时间的改善表明，锻炼可以有效地逆转或至少减缓某些年龄相关的运动表现和认知处理速度的下降。
This study evaluated the effects of a three-year exercise program on motor performance and cognitive processing speed of previously sedentary older women, ages 57-85. Variables tested were simple and choice reaction time (CRT), balance, sit and reach flexibility, shoulder flexibility, and grip strength. Subjects participated three times a week in exercise performance classes designed to meet American College of Sports Medicine guidelines. Results indicate that performance was significantly improved on all measures during the course of the study (p less than .01) except for the sit and reach test (SRT), where significance was approached (p less than .027), but not reached. A comparison of the exercise subjects with a comparable group of nonexercising control subjects revealed significant interactions between treatment and time on all variables except CRT and grip strength. Pretest to posttest scores of the exercise subjects tended to improve over the three-year period, whereas the scores of the control subjects declined. Improved reaction time indicated exercise is effective in reversing or at least slowing ceratin age-related declines in motor performance and in speed of cognitive processing.
