  1. Slower cognitive decline is associated with activity variability in humans.

    “Slower cognitive decline was associated with more favorable midday PA (10 AM–3 PM), including higher movement volume, less sedentary time, fewer interruptions to active periods, and greater activity variability.”

Slower cognitive decline linked to more midday movement

A cohort study linked cognitive changes in 811 older adults without cognitive impairment to activity patterns measured a median of 8.2 years later.A cohort study linked cognitive changes in 811 older adults without cognitive impairment to activity patterns measured a median of 8.2 years later.

Cohort study of 811 initially cognitively unimpaired older adults, median 8.2 yearsPopulations

Limit: Cognitive changes preceded activity measurement; declining cognition could explain lower movement
