This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. This study will determine if the energy expenditure of daily living can be precisely estimated. Energy expenditure from activity can be broken down into two groups: exercise-related thermogenesis and non-exercise activity thermogenesis (NEAT). NEAT is the energy expended during daily activities such as occupation, sitting, standing, and fidgeting. Due to the variety of the components of NEAT, it is challenging to measure. In this study a Physical Activity Measuring System (PAMS) will be used to measure NEAT. PAMS consists of small devices that can determine body position and motion. Subjects will wear PAMS in a free-living environment and in a lab setting where their energy expenditure will be measured during sitting, standing, and the transition between sitting and standing. The energy expenditure information obtained from PAMS will be compared to information obtained the lab testing. Differences in energy expenditure, walking velocity, walking movement, and minutes spent walking will be compared between lean and obese subjects. This comparison will give insight into the differences in energy balance between lean and obese humans.

这个子项目是许多利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 这项研究将确定是否可以精确地估计日常生活的能量消耗。 活动的能量消耗可以分为两组：运动相关产热和非运动活动产热（NEAT）。 NEAT是指在日常活动中消耗的能量，如占用，坐，站和坐立不安。 由于NEAT的组成成分多种多样，因此测量具有挑战性。 在这项研究中，身体活动测量系统（PAMS）将被用来测量NEAT。 PAMS由可以确定身体位置和运动的小型设备组成。 受试者将在自由生活环境和实验室环境中佩戴PAMS，在实验室环境中，将测量他们坐着、站立以及坐着和站立之间的过渡期间的能量消耗。 将从PAMS获得的能量消耗信息与实验室测试获得的信息进行比较。 将比较瘦型和肥胖型受试者之间的能量消耗、步行速度、步行运动和步行分钟数的差异。 这种比较将使我们深入了解精瘦和肥胖人群之间能量平衡的差异。
