Kevin Jacobs joined the faculty at the University of Miami in 2004. He completed his Masters in applied exercise physiology at San Diego State University in 1993 and worked as a research physiologist at the Naval Health Research Center in San Diego until 1995. He earned his Ph.D. in exercise physiology from The Ohio State University in 2000 and completed a four-year postdoctoral fellowship at the University of California, Berkeley and the Palo Alto VA Health Care System.

His research focus is human metabolism and more specifically the ways in which factors such as exercise intensity, nutritional status, training status, gender, age, menstrual cycle phase, and environment alter substrate (carbohydrate, fat, and protein) use at rest and during exercise. His research involves basic measurements such as the analysis of respiratory gas exchange and concentrations of various blood metabolites and hormones to more complex measurements of substrate turnover by stable isotope infusion and analysis. The results of his research not only further basic science, but are also applied to improving our understanding of the etiology of metabolic diseases such as obesity and non-insulin-dependent diabetes and developing more effective lifestyle interventions to prevent and treat these diseases. His research has involved men and women of various ages and levels of fitness as subjects that have been studied in environments as varied as a standard laboratory at sea level to a high-altitude research station at Pikes Peak, Colorado (14,100 ft. elevation).

While at the University of Miami, Dr. Jacobs and his students have investigated many topics including the metabolic effects of spinal cord injury, pharmacological and ischemic preconditioning effects on cardiovascular hemodynamics and exercise performance at simulated moderate and high altitudes, and pre-exercise sprints and glycemic control in type 1 diabetics during prolonged exercise.

Currently, Drs. Kevin Jacobs, David McMillan (KIN doctoral graduate and current postdoctoral fellow at The Miami Project to Cure Paralysis), and Mark Nash are studying the effects of spinal cord injury on fat metabolism in response to feeding and exercise.  This work will improve our understanding of disordered fat metabolism in this population, as well as the effectiveness of exercise in preventing excessive body fat accumulation.  The ultimate goal of this translational work is to guide the development of innovative rehabilitation strategies aimed at improving the quality of life of this population.  With funding from the Craig H. Neilsen Foundation, investigators are testing adult men with chronic paraplegia, tetraplegia, and age-matched control subjects without spinal cord injury.  The effects of spinal cord injury and an acute bout of upper body exercise on use of fats stored in the body as well as those from a recently ingested meal will be examined using novel stable isotope tracer methods and frequent blood and breath sampling.
