Discovery - Our research interests include human nutrition and exercise studies on protein, carbohydrate and energy metabolism, dietary protein and energy requirements, body composition, obesity, weight loss, muscle strength, and muscle function with special emphasis on aging. We are also interested in how nutrition, exercise, and aging impact appetite and ingestive behaviors. Our research suggests that older people who habitually consume the Recommended Dietary Allowance for protein experience subtle declines in skeletel muscle size. Thus we seek to find the preferred protein intake for older and elderly people to consume. Our research also focuses on how protein metabolism, body composition, and glucose metabolism change in older people with changes in protein intake, body weight, and exercise (especially strength training). We are also interested in evaluating the effectiveness of compounds that are promoted to have ergogenic properties (e.g. whey protein). The potential importance of the physical form of food (e.g. liquid versus solid) on appetite, ingestive behaviors, energy balance, and body weight control is also of great interest to our research team.
Our research includes the use of traditional metabolic balance techniques (with strict dietary control possible in a metabolic research kitchen), stable isotope infusion techniques (to measure in vivo amino acid turnover and incorporation into muscle tissues), body composition (plethysmography, dual x-ray absorptiometry, deuterium oxide dilution, magnetic resonance imaging and spectroscopy), the muscle biopsy technique (to obtain small samples of human skeletal muscle), and indirect calorimetry (to measure resting and exercise energy expenditure). We also highly value collaboration within and outside of Purdue to expand our interests, expertise, and research capabilities.
