This study by researches at the Massachusetts General Hospital, Boston, and the Broad Institute of MIT and Harvard, Cambridge, Massachusetts, examines whether moderate to vigorous physical activity concentrated in 1 to 2 days of the week (ie, a “weekend warrior” pattern) confers similar cardiovascular benefits as more evenly distributed physical activity.
Physical activity data from 89,573 individuals was analyzed, with a median follow-up time of 6.3 years..
In multivariable-adjusted analysis, both physical activity patterns were associated with similarly lower risks of atrial fibrillation, myocardial infarction, and heart failure at both guideline-based (150 minutes or more) and median (230.4 minutes or more) thresholds. Stroke associations also were similar, though significant only at the guideline-based threshold.
The researchers concluded that physical activity concentrated in 1 to 2 days was associated with similarly lower risks of cardiovascular outcomes as more regular activity.Read More >>
