J Am Geriatr Soc:四肢强壮,大脑才会强壮

近日,来自澳大利亚悉尼大学的一项新的研究发现表明,通过锻炼逐渐增加肌肉力量可改善机体的认知功能,该研究结果已发表于Journal of American Geriatrics。

研究采用随机双盲对照试验设计,纳入了100名轻度认知障碍的社区老人(年龄≥55岁),以确定渐进抗阻训练(PRT)后机体有氧能力和力量的改善是否会改善其认知能力。

干预措施为PRT和认知训练(CT),每周进行2-3天,共进行6个月。使用阿尔茨海默病评估量表–认知量表(ADAS-Cog);全球,执行,和记忆域;峰值强度(1重复最多);与VO2peak来进行评估。

结果显示,PRT可提高上身、下身及全身的力量,且VO2peak的变化比显著提高。较高的力量得分,但是并不是更高的VO2peak得分,与认知的显著改善相关。更强的下肢力量明显影响了PRT对ADAS-Cog的效果,以及整个大脑,但是并不会明显影响执行域。

该研究表明,高强度的PRT可显著改善轻度认知障碍老年患者的认知功能,肌肉力量和有氧能力。力量的获得,而非有氧能力的改变,接到了PRT对认知能力的影响作用。未来仍需更多的研究来确定与机体力量获得与认知受益之间相关的生理机制。
