AEROBIC FUNCTIONING AND MOBILITY PERFORMANCE IN OVERWEIGHT AND OBESE ADULTS

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。肥胖在所有美国人中是一个日益严重的问题，并与糖尿病、高血压、心脏病和骨关节炎等慢性疾病有关。它还与残疾有关，特别是行动不便，或行走和走动的问题。最近，研究人员还发现，在一些人中，肥胖可能与有氧适应能力差有关，或者在活动时出现呼吸困难和疲劳的问题。本研究的目的是探讨体重与有氧适能和活动障碍的关系。我们将研究中后期和老年的黑人和白人成年人，评估体重以及一个人S身体的脂肪、肌肉和骨骼数量，并了解身体组成与活动受限的关系。这些知识最终将被证明是有用的，有助于决定哪些人最需要运动干预，以及设计更有用的运动干预。

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. Obesity is a growing problem among all Americans and is associated with chronic diseases, including diabetes, hypertension, heart disease and osteoarthritis. It is also associated with disability, especially mobility impairment, or problems with walking and getting around. Recently, researchers have also discovered that in some people, obesity might be associated with poor aerobic fitness, or problems with breathlessness and fatigue during activity. The goals of this study are to investigate the relationship of body weight with aerobic fitness and mobility impairment. We will study black and white adults of late-middle age and older, assess body weight as well as the amount of fat, muscle and bone in a person s body, and see how body composition is related to mobility limitations. This knowledge will eventually prove useful in deciding which people most need exercise interventions and in designing more useful exercise interventions.
