Associate professors of kinesiology Graham Caldwell and Brian Umberger are the co-authors of an article recently recognized by science journal website ScienceDirect as one of the top 25 papers published in the Journal of Biomechanics in 2012.
The article, “Limitations to maximum sprinting speed imposed by muscle mechanical properties,” examines the effect of muscle mechanics on sprinting speed. It appeared in the April 2012 issue of the publication, widely considered to be the top journal in the field of biomechanics.
The article was co-authored with alumnus Ross Miller, who received his Ph.D. in 2011. Caldwell served as faculty mentor for Miller, now an associate professor of kinesiology at the University of Maryland, and whose doctoral dissertation research formed the basis of the publication.
Caldwell’s research investigates the kinematics and kinetics of human movement, using experimental data techniques such as 3D motion capture, force measurement and electromyography in conjunction with computer muscle models. His current projects examine the effect of age-related changes in muscular properties on balance, coordination changes while learning to direct external forces, and limitations on maximal sprinting speed.
Umberger researches the mechanics, energetics, and control of bipedal locomotion. He studies basic and clinical aspects of locomotion in humans and other bipeds, using a combination of experimental and computer modeling techniques. Much of his research is focused specifically on how the mechanical and energetic properties of skeletal muscles influence human movement.
