• Using Google Cloud AI to measure the physics of U.S. • freestyle snowboarding and skiing Nearly every snowboard trick carries a number. • A 1080 means three full rotations. • The convention is simple: add up every rotation around every axis and count in 180° increments. • For decades it’s served as the sport’s universal shorthand for difficulty. • Judges, coaches, and athletes all speak this language fluently.

  • Google Cloud has partnered with U.S. Ski & Snowboard to develop an AI tool that extracts full 3‑D biomechanical data from ordinary video footage, using Gemini and DeepMind computer‑vision models. The system tracks rotational speed, body posture, airtime, and actual geometric rotation of athletes, revealing a consistent gap between trick names (which count 360° per rotation) and the true physical rotation performed. For example, Shaun White’s Cab Double Cork 1440 was measured at only 1,122° instead of 1,440°, indicating mastery of axis control. A 2024 Sports Biomechanics study confirmed that corked tricks use about 25% fewer degrees than flatspins, highlighting the physics behind the naming convention.
