Strength and Fatigue Adaptations with Aging: Modeling a Paradox and Implications for Musculoskeletal Injury

Thursday, October 25, 2018 1:30 pm - 2:30 pm EDT (GMT -04:00)

Sun Life Financial Auditorium (Room 1621)
Lyle S. Hallman Institute (LHI)
University of Waterloo

With age, strength declines and fatigue is typically reported to increase beginning after the fifth decade of life. Yet isolated muscle fatigue properties have been shown to improve with age, with a preferential loss of type II fibers. These seemingly opposing findings are considered, using age-adapted Rohmert curves to examine how improved muscle fatigue properties may coexist with higher ratings of perceived fatigue, in conjunction with reduced strength. Implications for training, musculoskeletal injury and functional performance will be discussed.

CRE-MSD and the Hallman Lecture Series are pleased to present this free public lecture by Dr. Laura Frey Law, Associate Professor in the Department of Physical Therapy & Rehabilitation Science at the University of Iowa.

Laura's background includes BSE and MS degrees in biomedical engineering, along with MPT and PhD degrees in Physical Therapy and Rehabilitation Science, respectively. As director of the Neuromuscular Biomechanics Research Laboratory, her areas of research have focused on muscle strength and fatigue, involving both psychophysical assessments and mathematical modeling.  In addition, she studies musculoskeletal pain using a variety of methods, such as pain sensitivity testing and patient-reported outcomes in healthy and patient populations. She has published over 50 manuscripts and is an Associate Editor for the Journal of Applied Biomechanics.
