Achieving ≥150 minutes of moderate-to-vigorous activity just 1-2 days per week as a “weekend warrior” is associated with similar disease risk reduction as the same exercise volume spaced throughout the week, suggesting that total activity time is more important than the specific pattern.
Synopsis
This UK observational study compared health outcomes from achieving the recommended ≥150 minutes of moderate-to-vigorous physical activity weekly through a “weekend warrior” approach (1-2 days) against an evenly spread approach. Among 89,573 participants (mean age 62), both activity patterns correlated with lower risks for over 200 diseases. Weekend warriors had reduced risks of hypertension (HR 0.77), diabetes (HR 0.57), obesity (HR 0.55), and sleep apnea (HR 0.57); similar reductions were observed with regular activity for hypertension (HR 0.72), diabetes (HR 0.54), obesity (HR 0.44), and sleep apnea (HR 0.49). Total activity volume, rather than pattern, is key to lowering disease risk. [AI generated]
Weekend warrior: winning through total effort, not timing
Multiple guidelines recommend ≥150 minutes of moderate-to-vigorous physical activity (MVPA) per week, but there is no clear optimal pattern of MVPA. This study demonstrated that achieving ≥150 minutes of weekly MVPA through a “weekend warrior” routine or regular exercise had nearly equal associated risk reduction of up to 264 incident diseases, particularly for cardiometabolic conditions. Those these data cannot demonstrate causality, the authors performed multiple secondary analyses to account for potential confounding and reverse causation and demonstrated similar risk reduction among both groups, supporting their conclusion. Exercise patterns were determined using accelerometer data over just 1 week, so there is a chance that behavior patterns changed over the course of the study. Overall, I’m more inclined to advise busy patients to concentrate their exercise on just a few days a week if it helps them achieve a higher overall activity level, rather than aiming for daily exercise. Further studies are needed to assess factors such as target heart rate, resistance training vs cardio, and total exercise volume as they relate to disease risk.
