The two Figures show predicted health outcome response surfaces for school day activity compositions. Panel a displays predicted BMI-z score (a measure of body size) and Panel d displays predicted peak oxygen uptake (a measure of cardiorespiratory fitness) at the mean composition of sedentary time, light physical activity, and moderate-to-vigorous physical activity during the school day.

After adjustment for covariates and baseline values of the outcomes, the AS:Sk pilot intervention showed significant effects on sedentary time during the school day. There were no effects on physical activity, fitness, and body size.
