Research

Research Interest(s)

Dr. Herda's primary research interests include examining the effects of acute and chronic exercise and obesity on skeletal muscle composition and properties of motor units. Of particular interest to the Neuromechanics Laboratory is quantifying alterations in the composition of the muscle (muscle size, intramuscular fat, etc.) as a result of endurance- and resistance-training exercise interventions and, subsequently, the effects of changes in muscle composition may have on the neural costs to match force tasks. Dr. Herda also directs The Hawk Fitness Academy (HFA). HFA is a youth exercise program that is designed to improve muscle strength, agility and balance while teaching exercise techniques that can be used throughout adulthood.

He has published over 80 peer reviewed scientific articles in journals such as Acta Physiologica, Journal of Neurophysiology, Clinical Neurophysiology, Experimental Physiology, Medicine and Science in Sports and Exercise, European Journal of Applied Physiology, etc.
