Abbreviations MVPA moderate-to-vigorous physical activity, MVPA₁₀ moderate-to-vigorous physical activity in bouts of at least 10 min, Vigorous₁₀ Vigorous physical activity in bouts of at least 10 min, PAL Physical Activity Level (ratio of total daily energy expenditure to resting metabolic rate)
^a Adjusted for all minimization factors and baseline value of the outcome variable
^bN = 183 for sedentary time at 3 months; N = 184 for all other variables at 3 and 12 months
^c Confidence interval verified using a bias-corrected and accelerated bootstrap with 2000 replication
