Dr. Hortobágyi’s research focuses on the neuromechanical properties of the human musculoskeletal system. Dr. Hortobágyi has published original and review papers concerning neuromechanical adaptations to exercise training using lengthening muscle contractions in young and old adults. Another area of research he has been pursuing is adaptations in the nervous system before, during, and after exercise using various EMG techniques, including transcranial magnetic brain stimulation and muscle-to-muscle EMG coherence analysis. He collaborated with researchers at the Prince of Wales Medical Research Institute in Sydney, Australia, at the Sobell Department of Motor Neuroscience and Movement Disorders, Institute of Neurology, London, England, and most recently at the Human Motor Control Section, National Institute of Neurological Disorders and Stroke, Bethesda, MD, USA. He also intensively collaborates with Paul DeVita on locomotion biomechanics of obesity and osteoarthritis. He is an associate editor of the Journals of Gerontology and member of the Society of Neuroscience, International Society of Biomechanics, and a fellow of the American College of Sports Medicine. He is an avid tennis player and semi-professional cellist.
