A new study comes to show that the elderly over 60 years of age that are physically active have a reduced risk of diseases from all causes, are in better health, have a better quality of life and are less subject to risk of early death.
In France, there are 15 million people aged 60 years and more, they will be close to 24 million in 2060, of which 1.4 million were over 85 years of age. Life expectancy has plateaued in France, and one in good health is below the european average : 64.1 years for women and 62.7 for men, whereas the average in Europe is respectively 64.2 and 63.5 years, according to the latest Eurostat statistics bearing on 2016. The number of people with chronic illness, functional limitation, disability, more or less severe increases.
However, ” physical activity slows down the physiological changes associated with age, improves the health of older people in its dimensions physical, social and psychic and contributes to the prevention of chronic diseases related to old age “, pointed out a document of the High Authority of health July 2019. It also reduces the risk of a fall, as we had already mentioned.
The risk of cognitive decline was reduced from 26% to 38 % among those with levels of physical activity at a moderate to high

Among other results, the risk of cognitive decline was reduced from 38% among persons with levels of physical activity, low-or-zero, to 26% among those with levels of activity that are moderate to high. It has already been shown that physical exercise has effects on the volume of the hippocampus.
Research on biomarkers
To professor Bruno Vellas, coordinator of the gérontopôle of the CHU of Toulouse, this study falls within the scope of the ” géroscience “, a neologism that means ” a better understanding of the biological processes of aging, to prevent and/or delay the onset of disease and infirmity “, as he describes in an article in which he is the prime author, published on December 16, 2019 in The Journal of Prevention of Alzheimer’s Disease. The challenge is to determine the biological age and try to act on it.
