Study: See Gains w/Less Exercise
Researchers in Canada say recommendations for people to get at least 150 minutes of exercise per week to maintain health are overblown, suggesting in a study the level of physical activity needed for health benefits could be lower for many people.
The “move more and sit less” proposal by researchers at the University of British Columbia lines up with recent research showing exercise lowers risk for a plethoraof health conditions, but butts up against longstanding international recommendations.
The World Health Organization and U.S. Centers for Disease Control and Preventionboth recommend adults between the ages of 18 and 64 get at least 150 minutes of moderate-intensity aerobic activity, 75 minutes of vigorous-intensity aerobic activity or some combination of both per week.
While research has shown exercise can reduce the risk for more than 25 chronic medical conditions, the amount of exercise one needs is still being debated — with authors of the latest study claiming the requirement for 150 minutes per week was misunderstood as a minimum.
“The preponderance of evidence simply does not support this contention,” Dr. Darren Warburton and Dr. Shannon Bredin, researchers at the University of British Columbia write in the study, published in the Canadian Journal of Cardiology. “
There is compelling evidence that health benefits can be accrued at a lower volume and/or intensity of physical activity.
These health benefits are seen in both healthy and clinical populations.”
