At PCU, we recently installed Axioforce plates into our mound.
It has been a game changer for our development process and helping us understand lower half mechanics better.
Below is one of clients running it up to 92 at 160 pounds!
Brock has truly optimized his lower half mechanics with an unbelievable ability to create 200% of his body weight in Z force (straight down) and 82% of Y force (pushing off the rubber).
Our general benchmarks are to be at least 150% back leg peak Z and 50% back leg peak Y.
He also does an incredible job producing force in the Y direction with the lead leg (pushing back into the body/lead leg block). Producing 108% of his body weight in force with the our standard benchmark being around 100%.
Not only does he produce the force but he transfer it to the upper body super fast as you can see by how fast the green line shoots back up to 0 (clawback time).
Some cool things we look at with the shapes of these lines are the sharpness and smoothness.
Notice how the back leg Z and Y lines look like a wave or a ramp into the peak? That’s what we want. We are trying to avoid slow, flat hills.
Another really cool thing to note is the last dip/valley before the z force goes up into its peak with the back leg. Where that last valley is, is around top of leg lift.
This is where the player is their lightest before going into the load and stride. In most cases we want this to be as low as possible to set up max force production into the back leg when it’s go time.
A cue I sometimes give guys is to make yourself as light as possible into leg lift and then as heavy as possible when you go into your load.
Another helpful cue is to imagine you’re standing on a scale that has the meter pointing to the number you weigh. If you were to push on it fast, the meter would quickly shoot to a high number.
The goal with our delivery is to make the number be as close to 0 as possible into leg lift and then see how fast and how much weight you can get it to say when you go into your load. And how long you can hold it for.
If you haven’t spent time with a force plate mound, these graphs and metrics might be confusing. I’d love to answer any questions you might have!
