Exercise Physiology The Exercise Physiology Laboratory in the Department of Kinesiology is located in room 305 of the Rickel Building. The lab is shared by two exercise physiology faculty. It contains a variety of basic equipment for human performance assessment (treadmills, cycle ergometers, metabolic carts, heat chamber and strength testing devices), as well as a blood chemistry lab equipped to perform basic blood assays. Equipment includes a spectrophotometer, fluorometer, osmometer, an electrolyte analyzer, a gamma counter, centrifuges, ultra low freezer, cell harvester, biological hood, incubators, and equipment for molecular measurements (thermal cycler, UV illuminator,etc.). With this equipment we have the ability to conduct a variety of research projects dealing with the applied aspects of exercise metabolism and performance. The laboratory is used to conduct: 1) class laboratory exercises at both the undergraduate and graduate levels, 2) senior research projects for the undergraduate movement science majors, 3) masterÆs thesis projects, and 4) faculty research projects. Students at all levels are encouraged to participate in ongoing research in the Exercise Physiology Laboratory, either to satisfy requirements, or simply to broaden their research experience. Located in Room 259 D.Upton@tcu.edu Dr. Mitchell has focused primarily on projects dealing with fluid balance and thermoregulation during exercise, particularly in warm environments. He has investigated various fluid replacement regimens during and after dehydrating exercise with an emphasis on the influence of fluid volume and composition on gastric emptying, exercise performance, and fluid retention. Research funding has been obtained from internal grants as well as external support from the USTA, Coca Cola Inc., the Gatorade Sport Science Institute and other corporations. Other projects conducted by Dr. Mitchell have dealt with the influence of acute and chronic exercise on immune system function.
