Force-Velocity Profiling
USC High-Performance Sport
Force-Velocity Relationships
Coefficient of determination showing the variance in force explained by velocity.
Optimal Force-Velocity Profiles
The black line displays the current force-velocity profile, while the dashed green line displays the optimal force-velocity profile. Addressing the 90-degree profile deficits (if applicable) will improve lower-body power directed vertically. In contrast, addressing the 30-degree profile deficits (if applicable) will improve lower-body power directed horizontally.
