Long-Term Leisure-Time Physical Activity Intensity and All-Cause and Cause-Specific Mortality

The 2018 physical activity guidelines for Americans recommend a minimum of 150 to 300 min/wk of moderate physical activity (MPA), 75 to 150 min/wk of vigorous physical activity (VPA), or an equivalent combination of both. However,

Circulation lower risk of cardiovascular and noncardiovascular mortality. Higher levels of either vigorous or moderate physical activity were not clearly associated with incremental benefit or harm.

As established in previous studies, these findings demonstrate the substantial mortality risk reduction associated with regular moderate or vigorous physical activity and suggest that performing at least 150 to 300 minutes of vigorous or 300 to 600 minutes of moderate physical activity per week may be optimal to achieve benefits.

What Is New?•A comprehensive analysis of the association between long-term physical activity intensity and mortality that uses repeated measures of physical activity is lacking.•The nearly maximal benefit on mortality reduction was observed among individuals who reported ≈150 to 300 min/wk of long-term leisure-time vig-orous physical activity, 300 to 600 min/wk of long-term leisure-time moderate physical activity, or an equivalent combination of both.•No harmful association was shown among individu-als who reported >4 times the recommended mini-mum levels of long-term leisure-time moderate and vigorous physical activity.

What Are the Clinical Implications?•These findings support the current physical activity guidelines and further suggest higher levels of long-term leisure-time vigorous and moderate physical activity to achieve the maximum benefit of mortality reduction.
