These findings challenge current threshold-based messaging related to physical activity and health. The relationships between physical activity and health outcomes are generally curvilinear such that marked health benefits are observed with relatively minor volumes of physical activity. Research has also shown that regular exercise protects against many chronic conditions, excessive weight gain, and obesity. Systematic reviews and/or meta-analyses (based largely on epidemiological studies consisting of large cohorts) have demonstrated a dose-response relationship between physical activity and premature mortality and the primary and secondary prevention of several chronic medical conditions. The health benefits of exercise are broad and include improving mental, cardiovascular, and structural well-being. This systematic review evaluates recent systematic reviews that have examined the relationship between physical activity and health status. According to Public Health England, adults participating in regular physical activity see a 20-30 reduction in risk of depression, and increased exercise has.

However, recent evidence has challenged this threshold-centered messaging as it may not be evidence-based and may create an unnecessary barrier to those who might benefit greatly from simply becoming more active. Many agencies have translated these recommendations to indicate that this volume of activity is the minimum required for health benefits. Most international guidelines recommend a goal of 150 min/week of moderate-to-vigorous intensity physical activity. The health benefits of physical activity and exercise are clear virtually everyone can benefit from becoming more physically active. Physical activity of amounts more than 60 minutes daily provides additional health benefits.
