The CHAMP Afterschool Program: Promoting Physical Activity & Health in Children

项目摘要 促进儿童和青少年时期增进健康和可持续的身体活动水平 有助于成人健康。少数民族儿童的健康差异与身体健康有关。 不活动。儿童健康活动运动计划（CHAMP）是一项基于证据的干预措施， 在运动表现、感知运动能力和身体活动方面显示出有影响力的结果， 体育教育和基于运动的环境。目前，有1000万儿童参加课外活动， 计划（ASP）的每一天，和ASP提供了一个很好的机会，以提高儿童的健康以外的 正规的学校环境，特别是考虑到体育课的减少。这一提议的随机化 一项群集对照试验将检查即时（前至后测试）和持续（干预后1年 随访）CHAMP-ASP对体力活动（主要结局）、运动表现、感知运动 能力、健康相关的身体素质和体重状况。CHAMP-ASP将由ASP工作人员实施 并将在位于密歇根州兰辛和伊普西兰蒂的ASP中进行。ASP将包括一个高少数 人口儿童（N = 264; CHAMP-ASP=132和对照=132）K-2年级学生（通常年龄为5-8岁）将 参与35分钟/天X 3天/周，持续19周（剂量为1995分钟）。目的是：（a）审查 CHAMP-ASP对身体活动、运动表现和感知的即时和持续影响 相对于对照ASP的运动能力，B）检查CHAMP的即时和持续作用， ASP对次要健康结果-健康相关的体能（心肺功能，肌肉 强度）和体重状况与随机分配到对照ASP的学校中的儿童相比，以及c）确定 感知的运动能力介导CHAMP-ASP对中度至剧烈身体活动的影响。 长期目标是在2010年期间提供一个可持续的，生态相关的，以证据为基础的计划。 在少数民族中，提高健康水平和增加体育活动的小学早期教育 人口研究结果可能会显着影响未来的身体活动干预，并支持 可持续的，生态相关的（由ASP工作人员提供）基于证据的计划（即，CHAMP）， 有助于长期促进儿童的身体活动和健康。

PROJECT ABSTRACT Promoting health-enhancing and sustainable physical activity levels across childhood and adolescence contributes to adult health. Health disparities are present in ethnic minority children and are linked to physical inactivity. The Children’s Health Activity Motor Program (CHAMP) is an evidence-based intervention that demonstrates impactful results on motor performance, perceived motor competence, and physical activity in physical education and movement-based settings. Currently, 10 million children participate in afterschool programs (ASPs) each day, and ASPs provide a great opportunity to enhance children’s health outside of the regular school environment, particularly given the decline in physical education. This proposed randomized cluster, controlled trial will examine the immediate (pre- to post-test) and sustained (1-year post-intervention follow-up) effects of CHAMP-ASP on physical activity (primary outcome), motor performance, perceived motor competence, health-related physical fitness, and weight status. CHAMP-ASP will be implemented by ASP staff and will be conducted in ASPs located in Lansing and Ypsilanti, Michigan. The ASPs will include a high minority population. Children (N = 264; CHAMP-ASP=132 and control=132) K-2 graders (typically ages 5-8 years) will participate 35 minutes/day X 3 days/week for 19 weeks (dose of 1995 minutes). The aims are to: a) examine the immediate and sustained effects of CHAMP-ASP on physical activity, motor performance, and perceived motor competence relative to the control ASP, b) examine the immediate and sustained effects of CHAMP- ASP on secondary health outcomes - health-related physical fitness (cardiorespiratory fitness, muscular strength), and weight status compared to children in schools randomized to control ASP, and c) determine if perceived motor competence mediates the effect of CHAMP-ASP on moderate-to-vigorous physical activity. The long-term goal is to provide a sustainable, ecologically-relevant, and evidence-based program during the early elementary years that is health-enhancing and increases physical activity in the ethnic minority population. Findings could significantly influence future physical activity interventions and support a sustainable, ecologically-relevant (delivered by ASP staff) evidence-based program (i.e., CHAMP) that contributes to long-term health-enhancing physical activity and health in children.
