Even a little exercise – about 15 minutes a day - can translate to health benefits, according to an observational study from Taiwan.
Researchers from Taiwan’s National Health Research Institutes found that individuals who exercised an average of 92 minutes a week had 14 percent reduced mortality compared with inactive people. This extended to three more years of life expectancy, according to the study published in the Lancet.
The authors surveyed 416,175 people who self-assessed how much they exercised. Participants were asked to recall the examples of exercises they did the previous month such as walking, brisk walking, jogging or running, which were categorized into inactive, low, medium, high or very high activity.
Most of the participants, 54% were inactive. In the findings, 22% identified as low, 14% as medium, and 5% each for high and very high activity levels.
They followed up with participants after an average of eight years to calculate mortality risk and life expectancy for each category. Researchers found that even 15 minutes of moderate intensity exercise “had significant health benefits when compared with individuals who were inactive,†according to the study.
People who exercised had less deaths and less cancer-related deaths than inactive individuals. “In Taiwan, if inactive individuals engage in low-volume daily exercise, one in six all-cause deaths could be postponed,†wrote lead author, Dr. Chi Pang Wen.
