Force-Velocity Profiling is such a valuable speed assessment: the input is just one sprint at 3kg and the output you can't get any other way.
Most assessments fall short because they just say what speed an athlete runs, but a FVP says how an athlete makes that speed. Now there's a simple, repeatable, and in-depth way to learn what makes an athlete fast and what's potentially holding them back.
RFmax (%): max ratio of force
-What it is: how much of an athlete's total force is directed horizontally at the start of a sprint
-Why it matters: reflects direction of force application
F0 (N/kg): theoretical max force
-What it is: the max horizontal force an athlete can produce from a standstill (zero velocity)
-Why it matters: reflects the “strength” end of the FVP
V0 (mph or m/s): theoretical max velocity
-What it is: an athlete's maximum velocity capacity (when force reaches zero)
-Why it matters: reflects the “speed” end of the FVP
DRF (%): decrease in ratio of force
-What it is: how quickly an athlete’s ratio of force decreases as speed increases
-Why it matters: closer to zero, better orientation and force application throughout the sprint
Pmax (W/kg): theoretical max power
-What it is: highest amount of power (force x speed) an athlete can generate
-Why it matters: an overall insight into explosiveness and acceleration-ability
