“…Four of the seven studies included in this review employed an observational study design [ 65 , 66 , 67 , 68 ]. One study assessed the associations between PA level and taxonomical composition of 373 older adults aged between 78–98 years old [ 66 ] and another study [ 68 ] used data from the American Gut Project to determine associations between PA/exercise and gut microbiome composition in older subjects.…”

“…Physical activity level was assessed using accelerometers [ 66 , 67 ], Frändin–Grimby Activity Scale (FGAS) [ 65 ] and IPAQ [ 64 ]. Only one study assessed physical function [ 64 ] using a chair-sit-and-reach test, grip strength, single-leg standing with eyes closed, and 30 s chair stand.…”

“…Nutrient intake was assessed using food frequency questionnaires (FFQ) [ 61 , 63 , 65 , 66 , 67 ] and a brief self-administered diet history questionnaire [ 63 ]. Two of the studies, one observational and one intervention, did not measure/take into account nutrient intake [ 64 , 68 ].…”

“…This is a relatively new topic of research. As such, human intervention studies are limited and there are only a few observational studies that have assessed this research question [ 61 , 63 , 64 , 65 , 66 , 67 , 68 ]. This systematic review aims to summarise results of human studies that assess the effects/associations of PA/exercise on the gut microbiome of older adults, to better understand whether physical activity can positively influence the gut microbiome of older adults and whether it can help promote healthy ageing.…”

Systematic Review of the Effects of Exercise and Physical Activity on the Gut Microbiome of Older Adults

Recent evidence suggests that exercise/physical activity (PA) can beneficially alter the gut microbiome composition of young people, but little is known about its effects in older adults. The aim of this systematic review was to summarize results of human studies that have assessed the effects/associations of PA/exercise on the gut microbiome of older adults and to better understand whether this can help promote healthy ageing. Seven studies were included in the review and overall, exercise and increased amounts of PA were associated with decreases in the abundance of several well-known harmful taxa and increases in the abundance of health-promoting taxa. Altogether, the findings from the included studies suggest that exercise/PA have a beneficial impact on the gut health of older adults by improving the gut microbiome composition. However, due to methodological and sampling disparities, it was not possible to reach a consensus on which taxa were most affected by exercise or PA.
