Table summary
This table displays the results of Regression equations and R values for association between 60- and 15-second epoch data for physical activity and sedentary behaviour outcome variables Regression equation (x = 60-second epoch, y = 15-second epoch) and R (appearing as column headers).
  Regression equation
(x = 60-second epoch, y = 15-second epoch)		 R2
Wear time (hours per day) y = 1.04x + 1.09 0.91
Total counts per day y = 0.79x + 4.54 0.87
Total physical activity (minutes per day) y = 0.91x + 17229.07 0.89
MVPA (minutes per day) y = 0.78x + 15.76 0.85
Light physical activity (minutes per day) y = 0.72x + 6.67 0.85
Sedentary time (minutes per day) y = 1.03x + 67.20 0.83
Steps per day y = 0.26x + 6438.22 0.08
MVPA = moderate-to-vigorous physical activity
Total physical activity = MVPA + light physical activity
