Regular exercise without extremities, such as brisk walking, can increase up to 4.5 years of life expectancy of a person over 40 years and will surely gain more years of life even if they are overweight, according to a major new Scientific American research.
The benefit of exercise seems to be independent of weight, age, sex and state of health (heart problems, cancer, etc.). The researchers found that even mildly obese who exercised regularly for 150 minutes per week, live on average 2.7 to 3.4 years longer (depending on how many are overweight) compared with those who are obese but not exercised.
Those merely overweight (not obese) and exercised for 150 minutes a week, live 3.9 years more on average than overweight not exercised. People of normal weight who also exercised for 150 minutes a week, live about 4.5 years longer than people of normal weight who do not exercise, and 7.2 years more than those who are obese and physically inactive.
Experts recommend regular aerobic exercise of moderate half hours (150 minutes) or 1.25 hours (75 minutes) high intensity every week. To moderate intensity exercises are those during which a man can talk, but not sing. As a high-intensity exercises are those over which man can say a few words without stopping to catch his breath.
Exercise has many benefits, as it maintains a normal weight, healthy bones, muscles and joints, promotes mental well-being and generally reduces the risk of various diseases, including some types of cancer.
