Dr. Keith Baar joins Ken and Dawn today for the second of his two-part interview for STEM-Talk. Keith is a renowned scientist in the emerging field of molecular exercise physiology who has made fundamental discoveries on how muscles grow bigger, stronger, and more fatigue resistant. He is the head of the Functional Molecular Biology Laboratory in the Department of Neurobiology, Physiology, and Behavior at the University of California, Davis. In his lab, he leads a team of researchers attempting to develop ways to improve muscle, tendon and ligament function. Part one of our interview, episode 62, covered Keith’s childhood in Canada and his undergrad years at the University of Michigan as well as his time at the University of California, Berkeley, where he earned a master’s degree in human biophysics. We talked about Keith’s work at the University of Illinois, where he received a doctorate in physiology and biophysics. We also covered Keith’s time in the lab of John Holloszy, who is known as the father of exercise research in the United States, as well as the five years Keith spent at the University of Dundee in Scotland. Episode 63 picks up with Keith explaining his decision to return to the states and join the faculty at the University of California, Davis.  Ken and Dawn then talk to Keith about his most recent research, some of which is looking at how to determine the best way to train, as well as what types of foods compliment training to decrease tendon and ligament injury and accelerate return to play. This work has the potential to improve muscle function not only in athletes, but also improve people’s quality of life as they age. Another key topic covered in part two of our interview is the research Keith is doing on a ketogenic diet and its potential to reduce cancer rates and improve cognition. Keith also provides his thoughts on what optimal workouts and nutrition should look like.
