A PATH (Promoting Activity and Trajectories of Health) for Children

项目摘要 儿童缺乏体育活动是一个主要的公共卫生风险因素，也是国家健康目标。 少数民族和低收入儿童参加的体育活动较少，并经历了 增加患心血管疾病的风险。因此，促进增进健康和可持续 儿童期和青春期的体力活动水平有助于他们日后的健康，因为 成年人。有必要对儿童体力活动进行干预，以解决发育迟缓问题 过程(即运动发展和心理结构，包括知觉 能力)，因为这些因素被确定为与体力活动相关。 这项研究将调查运动技能--儿童健康--的直接和长期影响 和运动计划(CHAMP)，关于运动能力、感知运动能力和身体素质 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 促进儿童健康的积极轨迹的干预战略。具体目标是 目的：1)检查CHAMP干预后的即刻效果(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的可持续效果(与对照相比 参与者)对运动能力、感知运动能力和体力活动的影响 3)检验和比较即时和长期的中介效应 运动能力知觉与体能关系的研究 学龄前儿童的活动。我们假设，与对照组相比，冠军组的儿童， 将表现出更高水平的运动能力、感知的运动能力和身体素质 干预后和3年随访期间的活动。这项研究将由一组 随机对照试验和CHAMP将在以少数和低收入为主的人群中实施 收入人口，学龄前儿童(N=300；3.5-5岁)。 30C 学前班的姑娘们 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。将对以下项目实施CHAMP干预 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 使用加速度计的水平，b)面向过程和产品的运动技能能力c)感知 运动能力。积极的发现将支持儿童早期运动能力的发展 能力和体力活动计划，促进积极和可持续的体力活动 有助于健康成长和发展的行为。

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.
