Profile
Dr. Horvath has taken a circuitous pathway to his current research interests and present location. After growing up in Santa Barbara during the 60’s and 70’s, he went to the University of California at Irvine when it was still in the middle of a cattle ranch. He received his B.S. in Biology with specialization in Ecology and Systematics. His undergraduate research was on defensive secondary plant compounds and the herbivore (insect) interaction. To move up to larger animals, Dr Horvath traveled to Upstate New York and went to graduate school at Cornell University in Ithaca. The subjects of his next research were larger –his M.S. thesis was on the Nutritional Ecology of White-tailed Deer. Getting closer to home, he shifted again doing a PhD dissertation on Dietary Fiber Analysis and Human Colonic Fermentation. After a post-doc with Dr Milton Weiser and Michael Duffy on large intestinal nutrient absorption and electrophysiology at the University at Buffalo, he joined the faculty of the Nutrition Program. Since being in the Nutrition Program, which is now part of the Department of Exercise and Nutrition Sciences, his research has evolved into the area of exercise nutrition as it relates to cardiovascular health and athletic performance (endurance, cognition and injury prevention).

Research Interests

  • Effect of carbohydrate and fat on the exercise performance of female athletes at different times of the menstrual cycle.
  • Energy metabolism changes during the menstrual cycle (resting metabolic rate, thermic effect of food, and post exercise substrate use).
  • Studies involve indirect calorimetry, RQ, dietary and activity measurements, blood metabolite and hormone/regulator measurements and biomechanical assessments. Studies have been done on runners, dancers, soccer players and non-athletes.
  • Cardiovascular Risk Factors and dietary fat in men and women.
  • Studies involve exercise training, blood lipid (TG, lipoproteins, apoproteins, etc.) assays, dietary manipulations.
  • Studies done in other laboratories:
  • The effect of antioxidants on delayed onset muscle injury (with Dr. Burton).
  • Diet and physical activity as predictors of successful therapy for lung cancer patients (with Dr. Brown).
