Influence of the physical activity level on the life expectancy

In Brazil, the index of elderly people is growing a lot if we compare with the previous centuries. With this increase, the elderly population tends to seek better health and keep their bodies in the best possible state.1As mentioned in the last update of the National Household Sample Survey (PNAD, Brazil 2017), the elderly had a growth margin of 16% from 2012 to 2016, being that the estimate of the Brazilian population would be 205.5 million , this means that about 29.6 million people in the country are elderly. According to studies by the Brazilian Institute of Geography and Statistics2 in 14 years, the elderly will surpass 41.5 million in Brazil, reaching 66.5 million in 2050. With this large increase, the country will have to demand new priorities in the area of public policies, mainly by improving the health fields where the focus is on the elderly. According to Camargos4 the elderly tend to become sicker and weaker when they reach age 60, this age may be different according to their past experiences, this would be the beginning of a poor self-perception of health. In the study by Fiedler3 it was shown that in the municipality of Joaçaba SC, 35% of the 370 elderly people over 60 years of age present inadequate functional capacity and need help to perform up to three activities.
