The Resistance Exercise Performance Laboratory, or REP Lab, focuses on the physiological and biomechanical responses to exercise. The aim of this lab group is to understand the underlying mechanisms leading to increases in muscle strength and power in various populations, primarily through the use of noninvasive techniques.
- Resistance Training
- Muscle Strength & Power
- Neuromuscular Function
- Muscle Hypertrophy
