Life expectancy grows nearly five years if we do physical exercise

New research concluded that physical activity increases life expectancy by almost five years
New research concluded that physical activity increases life expectancy by almost five years

People who exercise regularly live longer than those who do not, even when they are overweight. Even those who does half the amount recommended exercise live longer for almost 2 years. The inactive obese people shrink their life expectancy for up to 5-7 years.

To lead a healthy life, almost as important as eating is practicing some form of physical exercise. New research, published this week in PLoS Medicine - recently concluded that physical activity increases life expectancy by almost five years.

According to research conducted by the National Cancer Institute of the United States , physical activity during leisure time is associated with a longer life expectancy of up to 4.5 years.

This occurs even at relatively low levels of activity and body weight. Also, people who do exercise regularly, such as brisk walking, live longer than those who do not do any exercises, even when they are overweight.

For adults 18 to 64 years, the Department of Health and Human Services U.S. recommends aerobic activity of 2.5 hours of moderate intensity (for those who can talk but not sing when performing the exercise) or 1.25 hours with a vigorous level (for those who can say only a few words without stopping to catch their breath) a week.

Taking this fact into account, the studies analyzed data on more than 650,000 adults, mostly aged over 40 years. After accounting for other factors that might affect life expectancy, the researchers concluded that it was 3.4 years for those who got the recommended level of physical activity, while individuals who performed twice as hard to exercises Advised gained 4.2 years of life.

Even benefits were detected in the lower levels of activity: those who made ​​half the recommended amount of physical activity added 1.8 years to their lives.

The authors also examined how life expectancy has changed with activity in people with obesity . People who were obese and inactive had a 5-7 shorter life than those who were normal weight and moderate activity.

So, the 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).

The results suggested that physical activity at a level equivalent to brisk walking for 75 minutes a week was associated with an average increase of life expectancy of 1.8 years compared with those who did not exercise.

However, physical activity during leisure time in the level recommended by the World Health Organization (minimum of 150 minutes of brisk walking per week) was associated with an average life expectancy of 3.4 to 4.5 years doing nothing.
