Athletic Intelligence

Every player is chasing an edge, that small improvement that can change their game. Dr. Sasho Mackenzie has built his career studying exactly that. Known as “The Savant of Speed,” he’s a biomechanist who’s spent decades decoding how the body creates power and precision in motion. 

In this episode, Sasho joins GameChanger’s Aman Loomba and Alex Trezza to unpack the physics, biomechanics, and technology beyond his revolutionary Stack System – a tool that uses adjustable weights and intelligent feedback to train both overload (strength) and overspeed (quickness). 

You’ll hear: 
  • How overload and overspeed training can reshape a player’s swing
  • The science behind personalized bat fitting 
  • Why speed training is critical for youth athletes’ development 
  • How the Stack app’s adaptive algorithms keep training simple, effective, and data-driven
