Work with Glenn Fleisig, PhD | NotedSource
Dr. Glenn S. Fleisig is a distinguished Biomechanics
Research Director with over three decades of experience.
He developed research programs and laboratories at the
American Sports Medicine Institute (ASMI), where he also
founded the American Baseball Biomechanics Society. Dr.
Fleisig has served as an advisor for Major League
Baseball, USA Baseball, and Little League Baseball,
contributing significantly to instituting pitch count
safety limits in amateur baseball. He holds an adjunct
faculty position at the University of Alabama at
Birmingham and has authored over 200 publications and
delivered more than 350 presentations globally. His
achievements include creating ASMI's Student Research
Program, providing biomechanical analyses to thousands of
athletes, and securing over $5 million in research grants.
His research primarily focuses on throwing biomechanics,
joint biomechanics, and return to sport after surgery,
with extensive media coverage of his work.
