Table 2 Associations of overall and timing-specific moderate-to-vigorous physical activity with measures of physical function.

From: Moderate-to-vigorous physical activity duration is more important than timing for physical function in older adults

  1. B unstandardized linear regression coefficient, MVPA moderate-to-vigorous physical activity, CI confidence interval.
  2. aA positive association indicates better physical function accompanied by more time spent in MVPA.
  3. bA positive association indicates worse physical function accompanied by more time spent in MVPA.
  4. *p < 0.05; **p < 0.001.
