The study examined the effect of a body-mass-based home exercise program on cognitive functioning among 170 male and female elderly people (52-81 years). This program comprised five kinds of resistance exercises that elderly people can perform at home without supervision or specialized equipment using only their body mass for resistance. Various cognitive tasks were used to assess cognitive functioning, including a simple reaction task, Go/No-Go reaction task, Stroop task, serial subtraction task, and coincident timing task. These tasks were performed before and after a 3-month body-mass-based home exercise program. Although there were no significant improvements in the simple reaction and coincident timing tasks, significant improvement was shown in the Go/No-Go reaction task and serial subtraction task. This study shows that even simple resistance exercise, using only body mass for resistance, may be an effective method for preventing age-related cognitive decline of inhibitory control and working memory among elderly people.
该研究调查了一项基于体重的家庭锻炼计划对170名年龄在52至81岁之间的老年男女认知功能的影响。该计划包括五种阻力训练，老年人无需监督或使用专门设备，仅利用自身体重作为阻力就能在家中进行。研究使用了各种认知任务来评估认知功能，包括简单反应任务、Go/No-Go反应任务、斯特鲁普任务、连续减法任务和同步计时任务。这些任务在为期3个月的基于体重的家庭锻炼计划前后分别进行。虽然简单反应任务和同步计时任务没有显著改善，但Go/No-Go反应任务和连续减法任务有显著改善。这项研究表明，即使是仅利用自身体重作为阻力的简单阻力训练，也可能是预防老年人与年龄相关的抑制控制和工作记忆认知衰退的有效方法。
