Force-Velocity Profiling and Training Optimization Course

In this video, I will explain you the vjsim package. vjsim is not only a simulator and educational tool, but it also contains functions for analysis and plotting of the squat jump data (like the one below):

As will be the case with all the analysis videos in this course, I will provide both R Markdown and compiled PDFs under the course video. To explore more about vjsim and optimization model by Samozino et al. please check the references provided and also make sure to visit: mladenjovanovic.github.io/vjsim page and read all the vignettes and use the Shiny simulator.
