美国加州大学学者在阿尔茨海默病杂志发表研究称,60岁以上的老年人日行4000步以上有助于提高记忆力和和思维能力。
 
众所周知,多多活动对于改善老年人的认知非常重要的。
 
该研究发现,日行4000步的人,其大脑的海马体及其周围区域的大脑皮质较厚,也意味着其认知功能更强。
 
海马体主要负责学习和记忆,日常生活中的短期记忆都储存在海马体中。
 
相比之下,每天活动量较少的人大脑海马区域的皮质较薄,他们的认知功能也稍差。
 
本研究中,那些活动量较多的人在注意力、信息处理速度及执行力方面表现得更优秀。
 
脑容量和脑厚度都是通过神经影像学方法测量的,是量化大脑健康的指标。研究者指出,脑厚度是一个比脑容量更敏感的指标,它可以更早地量化大脑的细微变化,并且可以独立预测认知。
 
研究分析了29名60岁以上的成年人的七天内的活动量,根据日行步数分为两组:日行步数>4000步组和日行步数≤4000步。
