Workload. The Single Most Overlooked Aspect Of Arm Health P.2

 

In this 3 part series we will be showing you how to define, calculate and monitor workload. 

 

P.2  Understanding Workload

The discussion of training volume and recovery are both widely discussed topics. “Don’t play too much” and “make sure you get proper recovery” are things we hear from a young age. However measuring these things can become a little tricky. 

Before moving forward it is important to first have a functioning definition of “workload”. If you haven’t already check out… P.1 “Defining Workload”

Acute and Chronic Workloads are terms used to take a deeper look to what’s happening daily, weekly and monthly and so on. It is important to track both acute and chronic workloads to accurately determine approximately how much you should be throwing. The following is how to define these terms…

 

Acute Workload (A) =

 

Total Number of Throws x Effort Rate of Throws = Daily Workload

 

Average over 7 days = Acute Workload

 

Chronic Workload (C) =

 

Average of total workload over 4 weeks (28 days).

 

To accurately track and measure a healthier progression of throwing workload we utilize what is called the (Acute:Chronic Ratio). To calculate this, You take the Acute Workload and divide it by the Chronic Workload. This will typically give you a number such as the following…

 

Acute Workload (A) / Chronic Workload (C) = 1.017751479

This number is important because we want to maintain a progression of A:C Ratio between .7 and 1.3 to assure safe progression through a month. A study was done by our friends at Motus Global. They found that high increases in acute workload was a strong indicator of high injury risk. In other words we want to stay away from having large spikes in Acute workloads during the season to lower risk of injury.

We see it a lot with younger players, they take a summer or winter off and quickly jump right into long toss, bullpens and games. Early season injuries can oftentimes be avoided by simply utilizing a properly designed throwing progression. In a study done on MLB players it was shown that early season injury rate is higher than the end of season injury rate. In this study the following was stated…

 

“More work on training regimens could help identify strategies for increasing player conditioning and reducing the overall incidence of injuries.”

 

This meaning more focus on proper progression in training could produce less overall in season injuries. Below is a chart from this study showing month by month the injury rate in season…

To combat the ever growing stresses of year round baseball today it is crucial a player simply takes into account all throwing workload, properly progresses all throwing workload and maintains a point of focus on a development period in a calendar year. In future posts we will discuss application of how you can monitor workload yourself and how the sports technology market is helping players monitor workloads year round.
