DESCRIPTION: (Adapted from Investigator's Abstract) The long term objective of this research is to reduce the epidemic of child obesity that is afflicting U.S. society. Obese children who engage in vigorous exercise programs show beneficial effects on total body percent fat (percent BF) and visceral adipose tissue (VAT); however, little is known about how to prevent accretion of total body or visceral adiposity in high risk youths, such as African-American (AA) females. The primary aim is to test the hypothesis that a one year afternoon exercise program will reduce accretion of general and visceral adiposity in AA girls. The design will involve randomization of AA girls, eight to 10 years of age (n=200) into intervention or control groups. After one year, the groups will be compared to test the primary hypothesis. Then the girls will switch group assignments for the next year. The pattern of data over the three time points will show what happens over a two year period in which the youths are, or are not, involved in the exercise program. The measurements will include: (1) percent BF with dual-energy x-ray absorptiometry; (2) VAT with magnetic resonance imaging; (3) CV fitness with a multi-stage treadmill test; (4) CVD risk factors (i.e., the ratio of total to high density lipoprotein cholesterol, insulin, systolic blood pressure, and fibrinogen); (5) free-living exercise and diet; (6) psychosocial variables (i.e., self-efficacy and self-concept); C7) sexual maturation; (8) anthropometric measures. The exercise program will be implemented in neighborhood schools for 90 minutes each weekday afternoon. Transportation will be provided if needed. Sessions will include motor skill instruction and aerobic exercises. The investigators state that this project has important health implications for two reasons, as follow. (1) They state that there is a dearth of information concerning the effects of exercise interventions in school and community settings. (2) They further state that if this project shows that an afternoon exercise program reduces accretion of general and visceral adiposity and has a favorable impact on fitness and health in a population that is at high risk of obesity, then schools may be encouraged to implement similar interventions to prevent juvenile obesity and associated health problems.

描述：（根据调查员的摘要进行了改编）的长期目标 这项研究是为了减少受苦的儿童肥胖症的流行 美国社会。肥胖的儿童参加剧烈运动计划 对总体百分比脂肪（BF百分比）和内脏脂肪的有益影响 组织（增值税）;但是，关于如何防止总计积聚知之甚少 高风险青年的身体或内脏肥胖，例如非裔美国人（AA） 女性。主要目的是检验一个一年的下午的假设 锻炼计划将减少AA中的一般和内脏肥胖的积累 女孩们。该设计将涉及AA女孩的随机化，八到十年 年龄（n = 200）分为干预组或对照组。一年后，小组 将进行比较以检验主要假设。然后女孩们会切换 明年的小组分配。三次数据模式 积分将显示在两年的年轻人中发生的事情， 或不参与锻炼计划。测量将包括： （1）双能X射线吸收法的BF％； （2）带有磁性的增值税 共振成像； （3）带有多阶段跑步机测试的简历健身； （4）CVD 危险因素（即，总脂蛋白胆固醇的总比率 胰岛素，收缩压和纤维蛋白原）； （5）自由生活练习和 饮食; （6）社会心理变量（即自我效能和自我概念）； C7） 性成熟； （8）人体测量指标。练习计划将是 在每个工作日下午在附近学校实施90分钟。 如果需要，将提供运输。会议将包括运动技能 指导和有氧运动。调查人员指出这个项目 具有重要的健康含义，有两个原因，如下。 （1）他们说 关于锻炼影响的信息很少 在学校和社区环境中进行干预。 （2）他们进一步指出，如果 该项目表明，下午的锻炼计划减少了 一般和内脏肥胖，对健身和健康有利 在肥胖症高风险的人群中，可能会鼓励学校 实施类似的干预措施，以防止少年肥胖和相关 健康问题。
