Baseball Pitching Biomechanics with Glenn Fleisig - Episode 36

June 27, 2023·54 min

Deep-dive interview between Mike Reinald and Dr. Glenn Fleissig examining 40 years of baseball pitching biomechanics research. Core thesis: injury rates are rising not despite better training, but because athletes are maxed out year-round without recovery. Key findings include: year-round specialization is the biggest risk factor (not pitch types), ligaments heal differently than muscles and need periodization, proper mechanics matter more than pitch velocity, and Instagram coaching trends like short-arm delivery lack scientific support. Discussion includes recent markerless motion capture technology democratizing biomechanics analysis across all levels of baseball. Episode positioned as authoritative counter-narrative to viral training trends.
