PROJECT ABSTRACT Physical inactivity in children is a major public health risk factor and national health objective. Ethnic-minorities and low income children engage in less physical activity and experience an increased risk of cardiovascular disease. Thus, promoting health-enhancing and sustainable physical activity levels across childhood and adolescence contributes to their health later as adults. There is a need for pediatric physical activity interventions to address the developmental processes (i.e., motor development and psychological constructs including perceived competence) in young children as these factors are established correlates of physical activity. This study will investigate the immediate and long-term effects of a motor skills - the Child Health and Motor Program (CHAMP) on motor competence, perceived motor competence, and physical activity in preschool-age children. The long-term goal of our work is to provide evidence-based intervention strategies to promote positive trajectories of health in children. The specific aims are to: 1) examine the immediate post-intervention effect of CHAMP (compared to control participants) on motor competence, perceived motor competence, and physical activity in preschool-age children; 2) assess the sustainable effect of CHAMP (compared to control participants) on motor competence, perceived motor competence, and physical activity across middle childhood; and 3) examine and compare the immediate and long-term mediating effects of perceived motor competence on the relationship between motor competence and physical activity in preschool-age children. We hypothesize that children in CHAMP, compared to control, will demonstrate higher levels of motor competence, perceived motor competence, and physical activity at post-intervention and across the 3-year follow-up. This study will consist of a cluster randomized control trial and CHAMP will be implemented in a predominantly minority and low income population, Head Start preschoolers (N = 300; 3.5-5 years old). Thirty c lasses of preschool children will be randomly assigned to either the treatment (CHAMP, n = 15) or control (normal preschool free-play/recess, n = 15) condition. The CHAMP intervention will be implemented for 30 minutes/day 4 days per week for 30 weeks. Data will be collected on: a) 7-day physical activity levels using accelerometry, b) process- and product-oriented motor skill competence c) perceived motor competence. Positive findings will support the development of early childhood motor competence and physical activity programs that promote positive and sustainable physical activity behaviors that contribute to healthy growth and development.

项目摘要 儿童缺乏身体活动是一个主要的公共卫生风险因素和国家卫生目标。 少数民族和低收入家庭的儿童参加体育活动较少， 增加心血管疾病的风险。因此，促进增进健康和可持续的 儿童和青少年时期的身体活动水平有助于他们以后的健康， 成年人了有必要进行儿科体力活动干预，以解决发展中国家的儿童， 过程（即，运动发育和心理结构，包括感知 能力），因为这些因素与身体活动有关。 本研究将探讨运动技能的即时和长期影响-儿童健康 和运动计划（CHAMP）对运动能力，感知运动能力和身体 学龄前儿童的活动。我们工作的长期目标是提供基于证据的 干预战略，促进儿童健康的积极轨迹。具体目标是 1）检查CHAMP的即时干预后效应（与对照组相比 参与者）对运动能力、感知运动能力和身体活动的影响 学龄前儿童; 2）评估CHAMP的可持续影响（与对照组相比 运动能力，感知运动能力和身体活动 3）检查和比较即时和长期的中介效应 运动能力知觉与身体素质的关系 学龄前儿童的活动。我们假设，与对照组相比，CHAMP组的儿童， 将表现出更高水平的运动能力，感知运动能力和身体 干预后和3年随访期间的活动。这项研究将包括一个集群， 随机对照试验和CHAMP将在主要少数和低 收入人群，学前儿童（N = 300; 3.5-5岁）。 3C 学龄前儿童 儿童将被随机分配到治疗组（CHAMP，n = 15）或对照组（正常 学龄前自由玩耍/课间休息，n = 15）条件。CHAMP干预措施将实施， 30分钟/天，每周4天，持续30周。将收集以下数据：a）7天体力活动 水平使用加速度计，B）过程和产品导向的运动技能能力c）感知 运动能力积极的发现将支持儿童早期运动的发展 促进积极和可持续的身体活动的能力和身体活动计划 有助于健康成长和发展的行为。
