项目摘要

DESCRIPTION (provided by applicant): The aim of this proposal is to improve our understanding of factors related to cognitive health of school-aged children by examining the effects of a 9-month exercise intervention on basic and applied aspects of cognition in preadolescent children. From a basic measurement perspective, event-related brain potentials (i.e., neuroelectric activity in response to, or in preparation for, a stimulus or response) and behavioral (i.e., reaction time, response accuracy) indices of cognition will be studied during several tasks aimed at assessing various aspects of executive control (i.e., a subset of processes concerned with the selection, scheduling, and coordination of computational processes responsible for perception, memory, and action). Preliminary research has observed faster and more efficient performance in high-fit, relative to low-fit, children and adults using neuroelectric measures that reflect attentional allocation to environmental stimuli (i.e., P3) and response monitoring processes (i.e., ERN, Pe), along with behavioral measures that reflect response speed and accuracy. These preliminary findings indicate greater top-down attentional control may be associated with increases in physical activity. From an applied measurement perspective, preliminary research has found that children with greater aerobic fitness perform better on standardized achievement tests of reading and mathematics, compared to children with lower aerobic fitness, suggesting that exercise may be related to academic performance in an applied school setting. To date, no causal evidence exists regarding the effects of physical activity on neuroelectric, behavioral, or applied school performance indices of cognition in children. Accordingly, this proposal investigates an aerobic physical activity training intervention on these measures of cognition using three tasks (single stimulus, Go/NoGo, flanker) that require variable amounts of executive control, and on the Illinois Standardized Achievement Test using a randomized control design in which particiants are assigned to an afterschool physical activity program or a wait-list control group. Given recent trends identifying decreased levels of physical activity and health status in preadolescents, the understanding of the potential benefits of physical activity on cognition is of great interest. It is imperative that factors positively influencing cognitive function of children be examined to maximize health and effective functioning of individuals as they progress through the lifespan. PUBLIC HEALTH RELEVANCE: recent trends have identified decreasing levels of physical activity, fitness, and health in preadolescent children. Examining factors, such as physical activity behavior and aerobic fitness that positively influence cognitive health of school-age children are important for improving school performance, maximizing health, and improving the overall functioning of individuals as they progress through the human lifespan. A sample of preadolescent children from the Urbana, Illinois elementary school system will be randomly assigned to a 9- month afterschool program that focuses on either aerobic exercise or wait-list control group to determine the effects of physical activity on basic and applied aspects of cognition. Changes in neuroelectric and behavioral indices of cognitive function and performance on standardized academic achievement tests of mathematics and reading will be examined as a function of participation in the intervention. Preliminary research supports that physical activity is positively associated with basic and applied aspects of cognition, with a stronger relationship for tasks requiring extensive amounts of executive control. However, previous research has mainly focused on older adults, and little research has examined the relationship between physical activity and executive control in children. These findings will provide lifestyle considerations for children to improve their cognitive health across the lifespan.

描述（由申请人提供）：该提案的目的是通过检查9个月的运动干预对预成核儿童认知基本和应用方面的影响，以提高我们对与学龄儿童认知健康有关的因素的理解。从基本的测量角度来看，事件相关的大脑电位（即，响应或准备刺激或反应的神经电活动）和行为（即反应时间，响应时间，响应准确性）将在几个任务期间研究旨在评估执行控制的各个方面（即，与负责感知，记忆和行动的计算过程有关的选择，调度和协调的一部分流程）。初步研究观察到，使用神经电措施，相对于低适合的儿童和成人，高拟合的速度更快，更有效地表现，这些措施反映了对环境刺激的注意力分配（即P3）和响应监测过程（即，ERN，PE），PE），，PE），以及反映响应速度和准确性的行为度量。这些初步发现表明，自上而下的注意力控制可能与体育活动的增加有关。从应用测量的角度来看，初步研究发现，与有氧运动较低的儿童相比，具有较高有氧运动能力的儿童在阅读和数学的标准化成就测试中表现更好，这表明运动可能与应用学校环境中的学习成绩有关。迄今为止，尚无关于身体活动对儿童认知的神经自我，行为或应用学校表现指数的影响的因果证据。因此，该提案使用三个任务（单个刺激，go/nogo，侧翼）调查了对这些认知措施的有氧运动训练干预措施，这些任务需要可变量的执行控制，并在伊利诺伊州的标准化成就测试中使用随机的成就测试。哪些颗粒物被分配到后课后的体育活动计划或等待名单对照组。鉴于最新的趋势鉴定出降低的体育活动和健康状况的降低，因此对体育活动对认知的潜在益处的理解引起了人们的极大兴趣。必须检查对儿童认知功能的积极影响的因素，以最大程度地利用个人在整个生命周期中发展的健康和有效的功能。公共卫生相关性：最近的趋势已经确定了前儿童的体育锻炼，健身和健康水平的降低。检查因素行为和有氧运动的因素，从而对学龄儿童的认知健康产生积极的影响，对于改善学校表现，最大化健康和改善个人在人类寿命中进步时的整体功能至关重要。来自伊利诺伊州乌尔巴纳小学系统的春季前儿童的样本将随机分配到9个月的课后计划，该计划重点是有氧运动或等待列表对照组，以确定身体活动对认知基本和应用方面的影响。在标准化的数学和阅读中，在标准化的学术成就测试中，神经自我和行为指数的变化将作为参与干预的函数进行检查。初步研究支持，体育活动与认知的基本和应用方面呈正相关，并且在需要大量执行控制的任务中建立了更牢固的关系。但是，先前的研究主要集中在老年人上，很少研究儿童的体育活动与执行控制之间的关系。这些发现将为儿童提供生活方式的考虑，以改善整个生命周期的认知健康。
