"Weekend Warriors" See Survival Benefits

Exercising just a couple of times a week could help lower your mortality risk, finds an observational study in JAMA Internal Medicine.

Researchers examined data on nearly 64,000 U.K. adults aged 40 and older who reported on their activity level several times from 1994 through 2008. Activity levels were defined as follows:

  • Inactive: no moderate-to-vigorous activity

  • Insufficiently active: <150 minutes/week of moderate-intensity activity and <75 min/wk of vigorous-intensity activity

  • "Weekend warrior": ≥150 min/wk of moderate-intensity or ≥75 min/wk of vigorous-intensity activity from 1–2 sessions

  • Regularly active: ≥150 min/wk of moderate-intensity or ≥75 min/wk of vigorous-intensity activity from 3 or more sessions

During some 9 years' follow-up, 8800 participants died, including 2800 from cardiovascular disease (CVD) and 2500 from cancer. Compared with inactive adults, insufficiently active adults and weekend warriors had significant risk reductions in all-cause mortality (about 30%) and CVD mortality (about 40%); regularly active adults had slightly greater risk reductions. Reductions in cancer mortality ranged from 14% for insufficiently active adults to 21% for regularly active adults.
