The Metabolism and Body Composition Laboratory is equipped to study metabolic, thermal and cardiorespiratory responses to exercise, and body composition assessed using a four-component model. Research in the past focused on the interaction among body composition, physical performance and metabolic responses to exercise in children and recreational athletes, and the validation of body composition methods using a four-component model. Recent research has focused on the metabolic consequences of cardiovascular drift in heat stress, physiological effects of fluid replacement beverages, and the effect of resistance exercise on postprandial lipemia. The Laboratory includes an a large exercise testing room, a prep room and bathroom, a blood chemistry room, an environmental chamber, an underwater weighing room and a DXAroom. Equipment includes a treadmill, Lode and Monarch cycle ergometers, PARVO Medics metabolic carts, a ventilated hood system for measuring resting metabolic rate, equipment for measuring cardiac output by CO2-rebreathing, an automated system for recording body temperatures, a Biopac system for measuring skin blood flow by laser Doppler flowmetry, equipment for blood chemistry (YSI glucose/lactate analyzer, electrolyte analyzer, osmometer, microhematocrit centrifuge, refrigerated centrifuge), a GE-lunar iDXA, and an underwater weighing system.
