Off-Season Workload Progression using Pulse


By Stephen Hart, Pitching Coordinator

Pitchers, particularly high-level pitchers, are creatures of behavior.  Most pitchers have a particular warm-up routine, a pregame playlist, and a pre-pitch routine. Some might actually have a routine throwing program they make the most of after their season ends. For a lot of, it’s common to take 2-3 months off from throwing. 

For some, this routine can work. However for a lot of, this routine can go away a variety of participant growth on the desk as that throwing timeline leaves hardly any time to enhance their arsenal, velocity, or command.  Such was the case for one among our skilled athletes earlier than he reported for Spring Coaching.

Proposing to begin throwing 1-2 months earlier in an offseason can create some hesitation amongst high-level pitchers. At Driveline, we have now discovered that intelligently constructing our athletes again to season type utilizing insights from Pulse helps ease that feeling of hesitation for athletes.  

This weblog will define how we, and any coach, can use Pulse to assist guarantee our athletes are ready for Day 1 of Spring Coaching, the opening weekend of convention play, and enhance their possibilities of success.  Particularly, we’ll cowl:

  • The objectives of this system
  • The method we took (i.e., What numbers did we take a look at to assist monitor program adherence?)
  • Onboarding the athlete and offering coaching suggestions
  • The outcomes

Objectives of this system (plan of assault)

1. On ramping program to arrange his physique for increased depth coaching.  Leveraged overload balls completely to assist maintain peak torques decrease by serving to him regulate his depth.
2. Step by step introduce lighter weight balls to construct up throwing health and introduce the physique to increased (on common) torque values.
3. Reinforce arsenal adjustments utilizing Trackman, Edgertronic, and Supposed Zone monitoring whereas persevering with to push torque values increased earlier than ST.

Within the instance beneath, we’ll present what numbers we used to watch coaching that was completed remotely.

Numbers Monitored from Driveline Pulse 

There are a variety of metrics that may be discovered and tracked utilizing Pulse. Many might be fairly priceless for coaching! A few of these metrics embody 1-day workload (1DW), continual workload (CW), torque, arm velocity, arm slot, variety of throws, excessive effort throws, and fatigue models. Amongst all of the metrics, the first metrics we paid shut consideration to have been 1DW, common torque, and continual WL. Let’s assessment these metrics and the way they utilized to our athlete’s coaching. 

Put merely, 1DW is a quantity that quantifies the quantity of throwing an athlete does on any given day and at what depth. This contains any plyocare throws, catch play, lengthy toss, and so forth. It’s a easy, tangible quantity that gives suggestions on the athlete’s throwing.  The place usually, lighter throwing days will yield a decrease 1DW, whereas our bullpen or recreation days will yield a better 1DW. One can consider prescribing 1DWs as utilizing (really useful) guard rails on our athlete’s coaching quantity.

Nonetheless, not all 1DWs are created equal, because the throwing depth element should be thought of. For instance, two athletes can have the identical 1DW, however the time it may possibly take to succeed in that 1DW might be very completely different primarily based on how exhausting they’re throwing (i.e. their depth). In different phrases, you may throw so much at a decrease depth, OR you may throw much less at a better depth and attain the identical 1DW.  

So, if 1DW may be very priceless but doesn’t inform the entire story of an athlete’s coaching session, what complementary metric can we use to present us insights into the throwing depth of the session?  That is the place common torque comes into play. The more durable the athlete throws in a given session, assuming the athlete locations the sensor appropriately, the upper his common torque. Conveniently, each these numbers are athlete/coach going through and might be discovered proper on the primary display screen within the Pulse app. This may be seen beneath within the examples of a bullpen (left) and restoration (proper) day.

On this approach, I view 1DW and common torque as complementary metrics that give me a way of throwing quantity and depth.  I feel all coaches ought to have the ability to monitor these two important variables in our applications.  The hidden energy of monitoring these metrics is twofold :

  • Regardless of this system being largely accomplished remotely, I can objectively see how this system is being carried out.  I do know the throwing content material of every day, the quantity of throwing quantity (1DW), and the depth (avg torque) the athlete was uncovered to.
    • This additionally gives us goal info and adaptability to pivot and alter the next day’s program if the athlete has irregular throwing days. 
  • Prescribing 1DWs creates an incredible quantity of accountability for the athlete.  Broadly, they perceive what they’ve for throwing that day (gentle, medium, or excessive depth) and the prescribed 1DW they’re attempting to succeed in.  Inside these constraints or guard rails, as I prefer to view them, the athlete can discover their mechanics, a drill, and so forth., in the event that they want to and are now not constrained by particular units and reps.  Within the instance beneath, our athlete was programmed to complete with a 1DW between 8 and 10.

Onboarding and coaching suggestions

Almost the entire onboarding and time spent gaining familiarity with the Pulse app was completed in particular person throughout his preliminary evaluation.  This was additionally a good time to debate the ‘what,’ ‘the place,’ and ‘why’ with all issues suggestions associated to his coaching utilizing Pulse.

  1. What metrics will we be centered on for coaching?
    1. Main, 1DW, and common torque
    2. Secondary, continual workload
  2. The place can you discover these metrics within the app?
    1. See image above 
  3. Why are we centered on them?
    1. See part above 
    2. The most important self-feedback or studying instruments used within the early phases of coaching revolved round common torque.  And figuring out the broad vary of common torque we will count on for every throwing day.  Beneath are examples of every throwing day and the typical torque imposed.

  1. As a result of this program was designed to take our athlete from Day 1 of throwing to Spring Coaching, protecting shut tabs on his 1DW and the gradual publicity to rising avg torque values was important for fulfillment.  The desk beneath outlines the gradual development and adjustments made to this system over the 16 weeks.  In addition to the noticed development of torque publicity and continual workload. 

The outcomes

General the low season program was an incredible success.  We have been capable of enhance his arsenal (by way of the addition of a brand new pitch), however we may intelligently construct up our athlete’s throwing health to higher put together his physique for Spring Coaching than in earlier years.  To not point out our athlete was capable of hit an low season PR of 94.

As mentioned earlier, breaking or creating new habits might be an uphill battle for some athletes.  Leveraging assets similar to Pulse and utilizing it as a information to offer path for programming and throwing development is invaluable.
