Illustration of the effects of the identified optimal cut-points for the vertical axis of the Actigraph being placed at the hip and wrist for a 9-yr old female participant.

<p>Note: the horizontal solid line specifies the cut-points for both the hip (100 counts per min; left Y-axis) and wrist (1756 counts per min; right Y-axis).</p

Flow mediated dilation (FMD) responses of obese subjects during the control moderate intensity and high intensity exercise conditions.

<p>Statistical analyses revealed the following: No significant differences between lean and obese subjects at baseline for any condition; FMD in lean subjects increased significantly compared to baseline at 2 h and 4 h in the absence of exercise (p<0.02) with no change observed in obese subjects; FMD change over time in lean subjects was greater than obese subjects during the no exercise control condition (p = 0.011); following high-intensity exercise, FMD in lean subjects was increased significantly compared to baseline at all time points (p<0.001) and these values were greater than those achieved on the control day (p<0.02) and greater than the peak values observed in obese subjects (p<0.0005).</p
