Human Performance Lab

Human Performance Lab

The University of Dallas Human Performance Laboratory is a multifunctional facility. Equipment is state-of-the-art and allows students and faculty to perform research and investigate techniques used in biomechanics, exercise science, and performance training.

Areas of interest include human motion analysis using kinematic/dynamic studies. Balance, movement, and gait assessment in elderly for fall prevention are focused areas of research.

Our video motion analysis and intertial measurement units allow for the collection of quantifiable data on position in plane, position vs. time, angular velocity & acceleration, angle, rotation (6DOF), acceleration, average, median & FIR filters, stick figure plot, and spline interpolation. This coupled with electromyography and work physiology provide a robust performance profile.

2018 Galbraith Lecture Explores 'Dante and Liturgical Time'

As we age, most of us ask ourselves, where has the time gone? Borrowing text from UD's Core curriculum, this spring semester's Galbraith Lecture will explore the difference between our own perception of time, and how the philosopher-poet Dante Alighieri viewed mankind's immortal clock, steeped in Scripture and in life.

Politics Major Empowers Youth, Shares Story Through Theater

Although she herself is not able to vote, Liz Magallanes, BA '18, works to make voting possible for other people. She first got involved with the organization Mi Familia Vota in 2014 and has been contributing to their endeavors ever since, including working with high school students in Dallas ISD. Additionally, she recently had a role in the play "Deferred Action."
