Measuring A Single Throws Value
When we look at a single throw traditionally we categorize it by RPE (Rate of Perceived Exertion).
The issue with determining a throws value by RPE is that most players do not effectively categorize a throws intensity from feel.
With advancements in technology we can now track exact stress per throw and apply objective measures through daily training or play.
Lets look at how this is done.
NM (Newton Metre) represents torque on the arm during any single throw.
This torque will range from throw to throw.
Higher torque or “high effort throws” can be valued any Newton Metre reading above 45.
Lower torque of “lower effort throws” can be valued any Newton Metre reading below 45.
Typically as we progress in distance or velocity our stress value will progress as well.
Using this knowledge lets say our first throw today was a throw at 20NM.
Motus would track this throw and place a value of 20NM to it.
What Motus also does though is runs it through a calculation to normalize it to you.
Just as all throws are not created equal neither should all athletes.
Some athletes are much larger with longer limb length.
To take into account your individual size Motus calculates a single throw by taking NM and dividing it by height times weight. From there they raise this to the 1.3rd power.
Seems complicated but keep in mind this is all being auto generated as you throw and is not sometime you need to be worried about at any point in a day.
The Motus Sleeve does this for every throw through your game or training session.
Once your day is complete the Motus sleeve adds up all of your single throw values and creates what is called “Daily Workload” (DWL for short).
Daily Workload accounts for all stress and total volume per day.
This value can be used to develop uniquely individualized throwing plans and allow insight to how ready any given pitcher is to compete from a fatigue standpoint.
In our next video we will discuss how with daily workload over time we can calculate both Acute and Chronic workload.
We will cover further in part 2 of our Workload Workbook how you can use a dynamic throwing program based around these concepts to further advance your training structure.
