Is 'Weekend Warrior' Exercise Effective in Improving Heart Health?

Individuals struggling to allocate time for exercise amid a busy work week can opt to focus their moderate-to-vigorous physical activity on one to two days of the week, possibly during the weekend (1^✔ ✔Trusted Source

“Our analysis represents the largest study to address this question,” says lead author Shaan Khurshid, MD, MPH, a faculty member in the Demoulas Center for Cardiac Arrhythmias at MGH.

Khurshid and his colleagues examined data on 89,573 individuals in the prospective UK Biobank study who wore wrist accelerometers that recorded their total physical activity and time spent at different intensities for a full week.

Among participants, 33.7% were inactive (less than 150 minutes of moderate-to-vigorous physical activity per week), 42.2% were active weekend warriors (at least 150 minutes with at least half achieved in 1–2 days), and 24.0% were active-regular (at least 150 minutes with most exercise spread out over several days).

Comparing Cardiovascular Risk Reduction: Active Weekend Warriors vs. Active-Regular Participants

After adjustments, both activity patterns were associated with similarly lower risks of heart attack (27% and 35% lower risks for active weekend warriors and active-regular, respectively, compared with inactive), heart failure (38% and 36% lower risks), atrial fibrillation (22% and 19% lower risks), and stroke (21% and 17% lower risks).

The team also plans to assess whether weekend warrior–type activity might be associated with reduced risks of a broader spectrum of diseases.
