An Intelligent Physical Activity Monitor

说明(由申请人提供)：认识到需要关于所有人群的体力活动和健康之间的剂量/反应关系的具体和可靠的信息。在对体力活动和特定健康相关结果之间的剂量-反应关系进行系统评估和解释之前，需要新的方法来评估自由生活人口的体力活动和能量消耗(EE)。我们的目标是论证一种低成本、不显眼的加速模式获取和分析系统的可行性。这一工具将确定并量化产生这些模式的体力活动。在本计划结束时，我们将提供一种实用的智能系统，从成本和不引人注目的使用前景来看，从而使其成为大规模自由生活人口流行病学体力活动研究的首选工具。

DESCRIPTION (provided by applicant): There is a recognized need for specific and reliable information regarding the dose/response relationships between physical activity and health for all segments of the population. New methods for assessing physical activity and energy expenditure (EE) in free-living populations are needed before a systematic evaluation and interpretation of these dose-response relationships between physical activity and specific health-related results can be undertaken. Our objective is to demonstrate the feasibility of a low-cost, unobtrusive acceleration pattern acquisition and analysis system. This instrument will identify and quantify the physical activities that generate these patterns. At the end of this program, we will provide an intelligent system that is practical from both a cost and unobtrusive use prospective, thus making it an instrument of choice for epidemiologic physical activity studies of large free-living populations.
