🩻 The 4 Core Engineering Laws of the URSE Model
Human locomotion is a strict battle of balancing rotational torque across your pelvis where Net Torque must equal exactly Zero as detailed in Dr. Larry VanSuch’s series, the Ultimate Running Speed Equation (URSE).
The following four laws are universal biomechanical constants.
When applied, they hold the absolute mathematical key to answering every question you have ever had regarding athletic speed limitations, training plateaus, and genuine running efficiency.
- ⚡ Law 1: The Right Leg Constant — The Right Leg driving forward always generates Counter-Clockwise (CCW) torque across the pelvic axle.
- ⚡ Law 2: The Left Leg Constant — The Left Leg driving forward always generates Clockwise (CW) torque across the pelvic axle.
- ⚡ Law 3: The Pushing Team Alliance — The arms and torso actively rotate as one unified flywheel unit with respect to rotation to favor and reinforce the torque direction of the active pushing leg.
- ⚡ Law 4: The Solitary Counterweight — The airborne swing leg always works entirely alone with respect to torque direction to match, neutralize, and balance out the entire pushing team alliance (pushing leg, both arms, torso) to drag Net Torque back to exactly Zero.
Each of the articles listed below will be reviewed and clarified applying these four laws:
