Optimal Force-Velocity Profile for Sprinting: Is It All Bollocks? – Part 6
By Mladen Jovanovic on 01/01/2023In this sixth and final installment of this article series, I will explore whether the “causal” interpretation of the Force-Velocity Profiling "holds water” using N=1 testing.

Optimal Force-Velocity Profile for Sprinting: Is It All Bollocks? – Part 4
By Mladen Jovanovic on 07/12/2022In the previous installment, I have demonstrated how to perform sensitivity/optimization analysis of the Acceleration-Velocity Profile (AVP) using (1) probing method and (2) slope method. In this installment I will explain how to do it using the Force-Velocity Profile (FVP).

Optimal Force-Velocity Profile for Sprinting: Is it all bollocks? – Part 3
By Mladen Jovanovic on 21/11/2022In the next two parts of this article series, I will explain how the optimization of the Force-Velocity Profile (FVP) works. Before jumping into FVP optimization, I will first explain the same reasoning using the Acceleration-Velocity Profile (AVP) since it is easier to comprehend.

Create Custom Set and Rep Schemes With {STMr} – Module 2: Reps-Max Relationship
By Mladen Jovanovic on 15/05/2022This course module will introduce the elementary building block for creating set and rep schemes - the reps-max relationship. The first video in this module deals with some theory and introduces three models to “map out” the relationship between reps to failure and %1RM.

R for Sport Scientists – Fundamentals Course: Control Flow
By Mladen Jovanovic on 18/11/2021In this lecture, I will show you how you can control the flow of the R program using choices and loops. Loops should be generally avoided in R since they can be slow. It is crucial to understand them because sometimes they can not be avoided.
