The importance of the force-velocity profile
Exactly how you use the app is outside the scope of the article and podcast, but if you’re interested, check out episode 55 of the Science for Sport Podcast, where the app’s creator, Carlos Balsalobre, discusses it in detail.
Simply put, you will need to perform several exercises with increasing resistance. Let’s take the example of a jump. As physicist and healthy eating advocate Sir Isaac Newton helped us to understand: as things get heavier, movement gets slower. This means as you add weight to the movement, for example, by using a bar and plates, the app will track you getting slower.
After completing a number of jumps, you can start to plot a line of force (weight) vs. velocity. Ultimately, it is this which can help you to work out where to focus your training
“With a force-velocity profile, you’re going to track, for a given athlete, where the weaknesses are, and where is the margin for change and improvement,” Morin said.
When you have your well-determined line, you can use it to work out where there is the greatest room for improvement. To calculate precisely whether you are better off attacking the force or velocity end of the spectrum, Morin himself has produced some excellent spreadsheets. When you’ve done the math, you’ll know exactly where your focus needs to be.
According to Morin, even the most elite athletes can find areas of weakness using this method.
“Believe me, even elite people still have some margin of improvement.” Morin said.
