Leisure time physical activity and mortality: a detailed pooled analysis of the dose-response relationship.

ABSTRACT:

Importance

The 2008 Physical Activity Guidelines for Americans recommended a minimum of 75 vigorous-intensity or 150 moderate-intensity minutes per week (7.5 metabolic-equivalent hours per week) of aerobic activity for substantial health benefit and suggested additional benefits by doing more than double this amount. However, the upper limit of longevity benefit or possible harm with more physical activity is unclear.

Objective

To quantify the dose-response association between leisure time physical activity and mortality and define the upper limit of benefit or harm associated with increased levels of physical activity.

Design, setting, and participants

We pooled data from 6 studies in the National Cancer Institute Cohort Consortium (baseline 1992-2003). Population-ba
