The present study found that resistance training (RT) has a positive impact on overall cognitive function in older adults with different cognitive statuses. Both cognitively healthy and cognitively impaired older adults showed improved cognitive function after engaging in RT. However, short-term memory was only improved in the cognitively healthy group.
The present study investigated the impact of resistance training (RT) on cognitive function in older adults with different cognitive status by conducting a systematic review and meta-analysis of intervention studies. We performed a literature search with no restriction on publication year in MEDLINE, Embase, CINAHL, SPORTDiscus, and AgeLine from inception up to August 2020. Experimental studies investigating the impact of RT on the cognitive function of cognitively healthy (CH) and cognitively impaired (CI) older adults (>= 60 years) were included for analysis. Eighteen studies were included in the final analysis, of which ten studies investigated CH community-dwelling older adult, seven studies investigated CI older adults, and one study investigated both. RT significantly improved overall cognitive function in both CH (SMD = 0.54; 95% CI = 0.00 to 1.08, P = 0.047) and CI (SMD = 0.60; 95% CI = 0.21 to 1.16, P = 0.005) older adults. However, short-term memory was only improved in CH older adults (MD = -0.20; 95% CI = -0.25 to -0.15, P < 0.00001). In conclusion, RT improved overall cognitive function in CH and CI older adults, whereas short-term memory, assessed by the digit span of the WAIS III, was only significantly improved in CH older adults.
