Utilizing physical activity coordinators to increase physical activity among yout

描述（由申请人提供）：美国各地的儿童身体活动不足。作为回应，许多体育活动（PA）干预措施已经被开发和测试，大多数在学校环境中。不幸的是，这些对儿童PA的影响有限，如果有的话。我们认为，这种效果的缺乏是由于学校一级缺乏因材施教，因而缺乏制度化。为解决后一个问题，我们认为重要的是利用现有资源和利用现有政策。南卡罗来纳州设立了“体育活动协调员”的角色，在学生中推广课外体育活动。然而，虽然这些职位是由州法律规定的，但这些职位的个人往往缺乏培训和支持，无法最大限度地发挥其影响力。我们的长期目标是发展最佳实践，为全国运动提供信息，培训学校体育活动协调员，在学校内提供可在全国推广的综合学校体育活动计划（CSPAP）。当前申请的目标是：1)修改和扩展现有的CSPAP PA协调员培训课程；2)在我们的试点学校提供加强的PA协调员培训；3)对PA协调员实施CSPAP的过程进行评估；4)评估培训的有效性，以提高儿童客观测量的PA。本研究的目的是要确定适当训练语习协调员促进小学生语习的可接受性、可行性和有效性。这一目标将通过以下目标实现：目标1：为PA协调员开发一个增强的CSPAP培训课程和资源工具包。目标2：确定在小学环境中加强体育活动协调员培训和实施综合学校体育活动计划的可接受性/可行性。目的3：确定经过培训的PA协调员对提高小学生客观测量PA的有效性。我们将随机抽取四所学校接受PA协调员培训（n=2）或继续标准实践（n=2）。将进行全面的过程和影响评估，以确定干预的可接受性、影响实施保真度/剂量的因素，以及PA协调员通过加速度计增加儿童身体活动的有效性。

DESCRIPTION (provided by applicant): Children across the United States are insufficiently physically active. In response, numerous physical activity (PA) interventions have been developed and tested, the majority within the school setting. Unfortunately, these have resulted in limited, if any impact on children's PA. We feel that this absence of effect stems from a lack o tailoring at the school level and a resulting lack in institutionalization. To address the latter isue, we feel that it is important to leverage existing resources and capitalize on existing policies. Th state of South Carolina has instituted the role of "Physical Activity Coordinators" to promote PA among students across and beyond the school day. However, while these positions are mandated by state law, the individuals in these positions often lack the training and support to maximize their impact. Our long-term goal is to develop best practices to inform the national movement to train school PA Coordinators to deliver a Comprehensive School Physical Activity Program (CSPAP) within schools that can be disseminated across the country. The objectives of the current application are to: 1) modify and expand existing CSPAP training curricula for PA Coordinators; 2) deliver the enhanced PA Coordinator training in our pilot schools; 3) conduct process evaluation on the implementation of a CSPAP by the PA Coordinators, and 4) evaluate the effectiveness of the trainings to increase children's objectively measured PA. The goal of the proposed study is to determine the acceptability, feasibility, and effectiveness of properly traine PA Coordinators to promote PA in elementary school children. This goal will be achieved through the following aims: AIM 1: Develop an enhanced CSPAP training course and resource toolkit for PA Coordinators. AIM 2: Determine the acceptability/feasibility of the enhanced PA coordinator training and the implementation of a Comprehensive School Physical Activity Program in an elementary school setting. AIM 3: Determine the effectiveness of trained PA coordinators to increase objectively measured PA in elementary school youth. We will randomize four schools to receive the PA Coordinator training (n=2) or continue standard practice (n=2). A comprehensive process and impact evaluation will be conducted to determine acceptability of the intervention, factors influencing implementation fidelity/dose, and the effectiveness of the PA Coordinators to increase physical activity measured via accelerometry in children.
