Dr. Glenn Fleisig: Director of Biomechanics Research at the American Sports Medicine Institute

In this episode of the PBATS Inside Athletic Training Podcast, we’re joined by Dr. Glenn Fleisig, one of the most accomplished and influential scientists in baseball biomechanics and sports medicine. Dr. Fleisig helped develop the American Sports Medicine Institute (ASMI) alongside Dr. James Andrews and has spent nearly four decades advancing research on pitching mechanics, injury prevention, and player health.We discuss Dr. Fleisig’s remarkable career journey, how biomechanics has transformed modern baseball, and the cutting-edge technologies shaping the future—from markerless motion capture to pitching labs and game data integration. The conversation also explores key recent studies on UCL injury risk factors, throwing programs, and training trends, as well as Dr. Fleisig’s role advising Major League Baseball, USA Baseball, and the broader baseball community.For more on Dr. Fleisig, please visit: Instagram: The Biomechanical ManAmerican Baseball Biomechanics Society: baseballbiomechanics.orgASMI: asmi.orgFor more information about PBATS and athletic training, visit pbats.com.
