Older people constitute a significant proportion of the total population and their number is projected to increase by more than half by 2050. This increasing probability of late survival comes with considerable individual, economic and social impact. Physical activity can influence the ageing process but the specific relationship with healthy ageing is unclear.
The authors conducted a systematic review and meta-analysis of longitudinal studies examining the associations of physical activity with healthy ageing.
The authors conclude that there is consistent evidence from longitudinal observational studies that physical activity is positively associated with healthy aging, regardless of definition and measurement.
