Force-velocity profiling is a method used to assess an individual's neuromuscular characteristics — particularly their ability to produce force and generate speed. It can be conducted through specific tests such as the Counter-Movement Jump (CMJ), Squat Jump, Long Jump, or isometric tests like the Maximum Isometric Strength Test.
The main goal of force-velocity profiling is to identify an athlete's unique strength and speed characteristics. Some athletes may be faster but less strong, while others may be stronger but slower. Based on these profiles, tailored training programs can be developed to address weaknesses and optimize overall performance.
Explanation of the Data
The data displayed at the top of the Force-Velocity Profile are not directly measured but are calculated theoretical values.
The measurement points can be seen on the blue graph on the left. A linear regression of these points (represented by the dotted blue line) is then calculated.
This curve is extrapolated to the right on the graph to estimate the force at zero speed (F₀) and the speed at zero force (V₀). The power is then calculated by multiplying these two values.
Interpreting the Data
The goal is to achieve the most linear Force-Velocity curve possible (maximize R²).
Secondly, the aim is to get as close as possible to the optimal profile, shown in green.
The performance of explosive actions is determined by power, which is the product of force and speed. Two athletes may have the same power but completely different profiles — one might rely more on strength, and the other more on velocity.
