In a study involving more than 400,000 people, those who exercised for 90 minutes a week were also 14 percent less likely to have died after eight years than those who were inactive, researchers at Taiwan’s National Health Research Institutes wrote in The Lancet medical journal today. Every extra 15 minutes of exercise reduced the risk by a further 4 percent.
The World Health Organization recommends adults aged 18 to 64 years exercise for at least 150 minutes a week. While one- third of American adults meet that goal, less than one-fifth of the population in East Asian nations such as China, Japan and Taiwan do, the authors wrote. The study shows that even a small amount of exercise can lower an individual’s risk of death and disease, and a nation’s health costs, they said.
“This advice is very simple and probably easily achievable,” Anil Nigam and Martin Juneau, researchers at the Montreal Heart Institute, wrote in an editorial accompanying the study. “Governments and health professionals both have major roles to play to spread this good news story and convince people of the importance of being at least minimally active.”
