How effective is physical activity, aimed at improving cardiorespiratory fitness, on cognitive function in older people (>55 years) without known cognitive impairment?
The cognitive functions which improved were not the same in each study, and the majority of comparisons yielded no significant results. Aerobic activity improves cardiovascular fitness, but it is not known whether this sort of fitness is necessary for improved cognitive function.
Physical activity is beneficial for healthy ageing. A regular exercise programme can slow down or prevent functional decline associated with ageing and improve health in this age group. It is thought it may also help maintain good cognitive function in older age.
