PHYSICAL ACTIVITY AND FITNESS ASSESSMENT IN YOUNG ADULTS

提出的研究比较了几种评价技术水平的方法 100名运动员和100名非运动员的习惯性体力活动(PA)与体能 男性和女性的年龄在20岁到59岁之间。这项研究将确定其可靠性 和各种评估工具的有效性来评估PA和 健身。PA将由明尼苏达州综合评审局反复评估 休闲时间PA问卷和较短问卷； 这些问卷将与来自24小时PA和食品的调查问卷进行比较 日记记录和机械运动探测器(Caltrac)。PA与饮食 每年将收集21次日记和运动探测器数据(3 一周中每天的时间)。身体健康将通过以下方式进行评估 使用Bruce协议和Beckman的跑步机运动测试 用于确定最大摄氧量(最大摄氧量)的代谢测量车。 结果将与估计的最大摄氧量进行比较。使用获取的值 更简单的次大踏步和自行车测功机测试；以及人体测量 测量，包括相对体重，多个皮褶厚度， 身体周长和水下称重法测定身体密度 和身体脂肪的百分比。将需要两年的时间来完成 对100个科目进行评估(每年50个)。最终目标是 为研究人员提供流行病学研究和临床试验指南 关于评估PA和体能的各种程序的相对优点 在信度、效度、实用性、成本和实施方面 要求。

The research proposed compares several methods of evaluating level of habitual physical activity (PA) and fitness in athletic and 100 nonathletic men and women age, 20 to 59. This research will determine the reliability and validity of a variety of evaluation tools for assessing PA and fitness. PA will be assessed repeatedly by the comprehensive Minnesota Leisure Time PA questionnaire and shorter questionnaires; the results of these questionnaires will be compared with those from 24 hour PA and food diary records and mechanical motion detectors (Caltrac). The PA and diet diary and the motion detectors data will be collected 21 times per year (3 times for each day of the week). Physical fitness will be assessed by treadmill exercise testing using the Bruce Protocol and the Beckman Metabolic Measurement Cart for determining maximal oxygen uptak (VO2 max). The results will be compared with estimated VO2 max. values obtained with simpler submaximal step and bicycle ergometer tests; and anthrophometric measurements, including relative body weight, multiple skinfold thickness, body circumferences, and underwater weighing determination of body density and percent body fat. Two years will be required to complete the assessments of the 100 subjects (50 per year). The ultimate goal is to provide researchers in epidemiologic studies and clinical trials guidelines about the relative merit of various procedures for assessing PA and fitness in terms of reliability, validity, practicality, costs and implementation requirements.
