This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. New Moves is an innovative school-based program for inactive high school girls who are overweight or at risk for becoming overweight due to low levels of physical activity. New Moves is an all girls alternative to regular high school physical education class. The program is offered during school hours and girls receive credit for participation. Throughout the fall semester, girls participate in physical activity four times a week and in discussions on nutrition and social support one time a week. In addition, the program includes individualized motivational interviewing and booster activities following the class such as "lunch bunches" and opportunities for physical activity. New Moves will be conducted in two waves with three intervention and three control schools in the 2007/2008 school year (approximately 220 girls) and with another six schools the following year (another 220 girls). Girls are recruited to participate the spring before the New Moves class is offered in the fall. Recruitment includes posters, flyers, and teacher¿s help to target girls who are inactive and uncomfortable in traditional co-ed physical education class. A screener survey is also used in recruitment to target girls who report low level of physical activity and preference is given to inactive girls who are greater than or equal to the 75th percentile of BMI for their age. The primary research hypothesis to be tested is that girls in the intervention condition will significantly decrease their percent body fat as compared to girls in the control condition. Girls will undergo three assessments; a baseline assessment after they are enrolled in New Moves in the spring before the intervention begins, one in the winter after the class is over and a follow-up assessment in the spring when the booster activities are complete. The GCRC will have a role in baseline and follow up evaluation of all 440 girls. Approximately ten girls will come to the GCRC during each visit and the visits will last approximately three hours. During the visits, GCRC staff will administer urine pregnancy tests and DEXA scans. Prior to having the DEXA scan, girls will take a pregnancy test. Girls who refuse the test or who are pregnant will not have a DEXA scan. During the GCRC visit, additional measures will be conducted by New Moves staff including a physical activity survey, a 24-hour dietary recall, a psychosocial survey and a measurement of body fat using a Bioelectrical Impedance Analyzer.

该子项目是利用该技术的众多研究子项目之一 资源由 NIH/NCRR 资助的中心拨款提供。子项目及 研究者 (PI) 可能已从 NIH 的另一个来源获得主要资金， 因此可以在其他 CRISP 条目中表示。列出的机构是 对于中心来说，它不一定是研究者的机构。 New Moves 是一项基于学校的创新计划，针对体重超标或因体力活动水平低而面临超重风险、不爱活动的高中女生。 New Moves 是一个全女生的常规高中体育课的替代课程。该计划在上课时间提供，女孩参与即可获得学分。在整个秋季学期，女生每周参加四次体育活动，每周参加一次有关营养和社会支持的讨论。此外，该计划还包括个性化的动机访谈和课后加强活动，例如“午餐束”和体育活动的机会。 新行动将在 2007/2008 学年分两波进行，其中包括三所干预学校和三所对照学校（约 220 名女生），次年将有另外六所学校（另外 220 名女生）。在秋季开设“新动作”课程之前，春季会招募女孩参加。招募包括海报、传单和教师帮助，以针对在传统男女混合体育课上不活跃和不舒服的女孩。在招募过程中还使用了筛选调查，以针对那些报告体力活动水平较低的女孩，并优先考虑 BMI 大于或等于同龄 75% 的不运动女孩。 要测试的主要研究假设是，与对照条件下的女孩相比，干预条件下的女孩的体脂百分比会显着降低。女孩将接受三项评估；春季干预开始前，他们参加新行动后进行基线评估，冬季课程结束后进行一次基线评估，春季助推活动完成后进行后续评估。 GCRC 将在所有 440 名女孩的基线和后续评估中发挥作用。每次访问期间大约有十名女孩来到 GCRC，访问持续大约三个小时。在访问期间，GCRC 工作人员将进行尿妊娠测试和 DEXA 扫描。在进行 DEXA 扫描之前，女孩将进行妊娠测试。拒绝测试或怀孕的女孩将不会接受 DEXA 扫描。在 GCRC 访问期间，New Moves 工作人员将采取额外措施，包括身体活动调查、24 小时饮食回忆、心理社会调查以及使用生物电阻抗分析仪测量身体脂肪。
