EFFECTS OF DIETARY COMPOSITION ON EXERCISE TOLERANCE IN OBESE ADULTS

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。我们建议在标准的跑步机行走测试之前、期间和之后测量年轻成年肥胖男性和女性的生理和心理参数，这些人被喂食含有不同数量和类型的碳水化合物以及不同数量的脂肪和蛋白质。本研究的主要结果是标准化运动测试期间的血清代谢燃料、葡萄糖和脂肪酸浓度，以及参与者在标准化运动测试期间和之后的心理反应。次要结果将集中在每周治疗期间的情绪，感知能量水平和运动感受的自由生活心理概况。

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. We propose to measure physiologic and psychological parameters before, during, and following standardized treadmill walking tests in young adult obese men and women who are fed diets containing diffrent amounts and types of carbohydrate and different amounts of fat and protein. The main outcomes of this study are serum concentrations of metabolic fuels, glucose and fatty acids, during standarized exercise testing, as well as participants' psychological responses during and following standardized exercise testing. Secondary outcomes will focus on free-living psychological profiles of mood, perceived energy level, and feelings about exercise over the course of each weekly treatment period.
