Researchers at King’s College London have found that muscle fitness as measured by power in the legs is strongly associated with an improved rate of ageing in the brain.
The findings, published in Gerontology, suggest that simple interventions, such as increased levels of walking, targeted to improve leg power in the long term may have an impact on healthy cognitive ageing. The research was funded jointly by the NIHR and the Wellcome Trust.
Scientists studied a sample of 324 healthy female twins from the TwinsUK volunteer registry over a ten-year period from 1999, measuring various health and lifestyle predictors.
Researchers were, therefore, able to control for genetic factors affecting changes in cognitive function.
