The Force-Velocity (F-V) Profile is built by measuring force or power at multiple loads — typically 4–6 jumps with progressively heavier external load, or sprints over different distances. A linear regression yields theoretical maximum force (F0, intercept on the force axis) and theoretical maximum velocity (V0, intercept on the velocity axis); their product gives maximum mechanical power (Pmax).
Comparing an athlete's F-V profile to an optimal profile for their sport identifies whether they have a force deficit (slope too steep — need to lift heavier) or a velocity deficit (slope too flat — need to move faster), which makes program-design decisions explicit instead of intuitive.
Originally developed by Samozino, Morin and colleagues; widely used in elite sprint and team-sport S&C labs.
Where it's used
S&C program design at high-performance levels with force plates or linear position transducers.
