(Best Syndication News) - The average lifespan increases 3 years with just 15 minutes of daily exercise (or 92 minutes each week) compared to those who did not exercise, according to a study from Taiwan. The study authors said that the longevity benefit of exercise was for all ages and sexes. It was also beneficial to those with cardiovascular disease. The study was published in The Lancet.

Senior author Xifeng Wu, M.D., Ph.D., professor and chair of The University of Texas MD Anderson Cancer Center Department of Epidemiology, said that exercising, even a very light amount, lowered a person’s death risk from any cause by 14 percent. Wu said that 150 minutes is the recommended weekly exercise duration, but even at 92 minutes, there are significant benefits.

Lead author Chi-Pang Wen, M.D., along with colleagues from the National Health Research Institutes of Taiwan, found that for every additional 15 minutes of exercise, up to a total of 100 minutes of exercise a day, a person’s death risk for any reason was reduced by 4 percent at each 15-minute increment. In this study, exercising for 30 minutes daily extended the life expectancy by around four years.

The researchers used prospective observational study data, which included 416,175 Taiwanese participants being followed for an average of 8 years. MJ Health Management Institution collected the data on participants between 1996 and 2008.

The participants completed an exercise questionnaire that assessed their medical history and physical activity. They asked the participants about their weekly exercise over the previous month. The participants reported how long they would exercise and how intense they would exercise. Light physical activity was considered walking. They also asked about moderate exercise, which was brisk walking, vigorous exercise which was jogging, or high vigorous exercise such as running. The participants also described their physical activity at work.

Based on the survey data, the researchers classified participants as being inactive if they reported less than one hour of leisure exercise per week. There were 54 percent classified as inactive. Then they would classify the remaining by how active they were based on how long they exercised and at what intensity.

The researchers found that even the low-volume exercise group had lower death rates than those who were in the inactive group. That was regardless of age, gender, or health status. It also was true in spite of tobacco use, alcohol consumption, or cardiovascular disease risk.
