Washington: Adults who engage in at least 150 minutes of moderate to vigorous activity each week live longer than inactive adults, a new study has found.Framing the benefits of exercise in terms of years of life gained may better motivate people than warnings about not exercising, said study author Ian Janssen, Ph.D., of Queen’s University in Ontario, Canada.Janssen and his team used data from the National Health and Nutrition Examination Survey, the National Health Interview Study mortality linkage, and U.S. Life Tables to estimate and compare the life expectancy at each age for adults who were inactive, somewhat-active and active. “Active” was defined as doing at least 150 minutes of moderate activity per week.They found that men at age 20 were estimated to gain as much as 2.4 years of life from moderate activity. Women at age 20 gained about 3 additional years from engaging in moderate activity. The biggest benefit from physical activity was seen in non-Hispanic black women, who gained as many as 5.5 potential years of life.Janssen hopes the positive message of the study can help health officials better relay the importance of exercise to the public.
