Overview
- The study, published Tuesday, Sept. 8, used wrist accelerometer data from 103,684 UK Biobank participants who wore trackers for seven days and were followed for about eight years during which 1,697 participants died.
- People who averaged 7,500–10,000 steps a day had the lowest associated risk of death, with smaller gains above that range, showing a point of diminishing returns for step volume.
- Among adults taking fewer than 5,000 steps a day, sustaining a brisk peak-30 cadence of about 80–100 steps per minute for roughly 30 minutes was associated with similar mortality reductions as higher step totals at slower paces.
- The study measured stepping intensity with 'peak 30-minute cadence' and found modeled benefits concentrated near 90–100 steps per minute, but authors warn wrist devices can miscount steps and the observational design cannot rule out reverse causation or residual confounding.
- Researchers and clinicians say the findings support flexible, personalized goals—either more steps or some brisk walking that fits a person’s ability—and note the 10,000-step target originated as a 1960s marketing goal rather than modern evidence.
