High Levels of Physical Activity Can Moderate Risks Linked to Sitting

The links between sedentary behavior and chronic disease risk are well known, however it is unclear whether physical activity can help moderate or even eliminate these risks. A review published in British medical journal Lancet examined the relationship between sedentary time, physical activity, and premature death from any cause. Researchers included 16 studies on over one million participants in the review.

The results showed that daily sitting time was not associated with death from any cause among the most active groups. Compared with those who sat less than four hours per day and were in the most active groups, people who sat over eight hours a day but got at least 35.5 MET hours of exercise each week saw no increased risk. In addition, watching television more than three hours per day was associated with higher risk of premature death regardless of activity levels, except in the most active group.

Many people sit for long periods due to their jobs and commutes. Health clubs provide a safe, effective place for people to get active and mitigate their health risks.
