Dose-Response Relationship – Exercise and Mortality

The Dose-Response relationship with regards to mortality rates is an important concept.

The following review, link to review, was published in JAMA Internal Medicine and came to the following conclusions:

Conclusions and Relevance  Meeting the 2008 Physical Activity Guidelines for Americans minimum by either moderate- or vigorous-intensity activities was associated with nearly the maximum longevity benefit. We observed a benefit threshold at approximately 3 to 5 times the recommended leisure time physical activity minimum and no excess risk at 10 or more times the minimum. In regard to mortality, health care professionals should encourage inactive adults to perform leisure time physical activity and do not need to discourage adults who already participate in high-activity levels.
