FVP Course: Module 2 – Theory – Part 3 - Complementary Training

# Force-Velocity Profiling and Training Optimization Course:

## MODULE 2: Theory – Part 3

### Optimization Model

What we are interested in once we have Force-Velocity profile is, which will yield better improvements in bodyweight squat jump height – increasing high force-low velocity capabilities (i.e. F0), or low force-high velocity capabilities (i.e. V0)? In this video, I am explaining the theoretical underpinnings of this optimization question given the squat jump model we have introduced. I am also explaining a few issues I have with this optimization model and what I think coaches should know when giving this model predictive or causal interpretation.

So far, there have been two studies implementing this optimization model to training (see Jiménez-Reyes et al. in the references) with favorable results. Underneath the video, you can find some of my thought regarding the study design.

Overall, besides explaining the optimization model, this video will also introduce philosophical issues I have with this model (i.e. assuming ontological realism perspective when utilizing this model).
