The New Moves study will evaluate the impact of a school based program for inactive high school girls who are overweight or at risk for being overweight due to low levels of physical activity. The primary study hypothesis is that girls in the intervention schools will significantly decrease their percent body fat as compared to girls in the control schools. Secondary research hypotheses include that girls in the intervention condition will significantly increase their physical activity levels and improve the quality of their dietary intake.
The purpose of the New Moves study is to evaluate the effectiveness of a school-based all girls alternative to regular physical education class for inactive high school girls. New Moves uses a large-scale community randomized controlled study involving girls from six intervention schools and six control schools. The New Moves class includes physical activity, nutritional guidance, and social support within a supportive, non-competitive environment. In addition the program includes individual counseling sessions. The primary research hypothesis is that girls in the intervention condition will significantly decrease their percent body fat as compared to girls in the control condition. Secondary research hypothesis to be tested are that girls in the intervention condition will significantly increase their level of physical activity and improve the quality of their dietary intake as compared to girls in the control condition. In addition a range of socioenvironmental, personal, and behavioral variables will be compared across conditions.

Level of Physical Activity
The 3DPAR assessed the sedentary behaviors and physical activities that study participants engaged in during each half hour time block between 6 AM and midnight on the three days previous to the day of data collection. In order to complete the 3DPAR, participants were provided with a list of 65 common sedentary behaviors and physical activities and were asked to select the activity that they participated in for the majority of every 30-minute block. The number of blocks of physical activity were summed for each day and then averaged over the 3 days. Outcomes was the average # of 30 minute blocks of physical activity.
