Explain how regular participation in physical activity can increase life expectancy

In the correct answer is: Regular participation in physical activity can increase life expectancy by reducing the risk of developing certain diseases. Regular physical activity can reduce the risk of developing certain types of cancers, osteoporosis, cardiovascular disease, and obesity. Reducing the risk of developing these diseases can lead to a greater life expectancy.

Explanation:

Physical activity during leisure time is associated with a longer life expectancy, up to 4.5 years, and even at relatively low levels of activity and body weight, according to studies conducted by a team of researchers led by the National Institute of the United States Cancer.

In addition, it was seen that people who exercise regularly, such as brisk walking, live longer than those who do not do any, even when they are overweight.

The Department of Health and Human Services of the United States recommends an aerobic activity of 2.5 hours of moderate intensity (which allows to speak but not to sing when the exercise is performed) at 1.25 hours with a vigorous level (they can only be said a few words without stopping to catch their breath) a week for adults 18 to 64 years.

After considering other factors that could affect life expectancy, the researchers concluded that this was 3.4 years longer for people who achieved the recommended level of physical activity, while individuals who made twice the effort to the exercises recommended They gained 4.2 years of life.

The authors also examined how life expectancy changed with activity in people with obesity: people who were obese and inactive had a life expectancy that was between five and seven years younger than people who had a normal weight and moderate activity.

Thus, people who do regular physical activity, such as brisk walking, live longer than those who do not exercise during their free time, even when they are overweight, with improvements in all levels of body mass index (BMI) .
