Using DASH with PULSEthrow
Here is an overview of the workload management tools available to you inside DASH. Note that some of these features are only part of a DASH PRO subscription and are not available with DASH LITE.
A/C Ratio: A:C Ratio or Acute: Chronic workload ratio is defined as the Acute Workload, short term average of Daily Workload, divided by the Chronic Workload, or a longer-term average of Daily Workload. A:C Ratio can also be defined as a measure of fatigue, which is the single most significant predictor of pitcher injury. The use of Acute: Chronic workload ratio monitoring helps to optimize athlete's performance and reduce their risk of injury.
Within the A:C Ratio column, the individual player's AC ratios are color-coded based on their number. 1.6 and higher are Red or in a "danger zone," 1.3 to 1.6 is yellow, or an area where the coach should use caution, .7-1.3 is green and where the pitcher is optimized. .4-.7 is Yellow because the pitcher is at risk of not being conditioned to handle acute spikes, and Below .4 is Red because the pitcher is not conditioned to handle any typical workload.
Acute Workload: Acute Workload is the Athletes most recent workload and is a weighted average of the last nine days of the Daily Workload. Today throw counts more than nine days ago. Acute Workload is a measure of fatigue.
Chronic Workload: This is a longer-term look at Workload and is a Rolling 28 day average of Daily Workload. Chronic Workload is a Measure of Fitness.
Arm Health: Arm Health is a subject measure gathered from the app, where an athlete manually enters on a 1-10 scale each day how their arm physically feels. It is an Acute Health rating and is an average of the numbers entered each day for the last seven days.
1-Day Workload: "1 Day Workload" is the Workload that the athlete should perform today. It's displayed in workload units. Workload units for specific throws vary from throw to throw and player to player for that matter. To find the workload unit for each player, we measure the peak amount of valgus torque applied to the elbow during the throw in Newton-meters. We then divide this value by the given athlete's height, in meters, times the weight, in kilograms. This newly calculated value is then taken to the power of 1.3. We are now left with the workload units for each individual throw. When we have the average workload units for the different types of throws, we can build out customized throwing programs for each athlete.
A/C Ratio With Rest: AC Ratio with Rest is a computation that assumes a player does not throw today. The AC Ratio shown is tomorrow's AC Ratio if indeed the player does not throw today.
Future Chronic Workloads & Future A/C Ratio: On the right of the DASH homepage, you'll find some past and future information. Starting at the top, you'll see a seven day and 28 day average of total throws and average torque normalized by height and weight. Just below, you'll find Future A:C Ratios and Workloads, which is a graph showing the last two and a half weeks of actual Workload and AC Ratio. You'll also see what the athletes future AC Ratio will be if they follow the prescribed Workload each day and stay on the same throwing schedule as the athlete or coach has entered in the Settings.
Future Chronic Workload shows the last two and a half weeks of the previous Workload and then two weeks in advance of what the goal is in terms of Workload, the simulated Workload, and how the athlete is advancing towards the Target workload number.
Long Term Trends: Long Term Trends enables you to visualize your entire roster's data in one view. Clicking on an Athlete's row will expand their data to see daily or weekly averages of that metric. You can select up to two metrics at a time, in either bar chart or line chart formatting. All metrics are color-coded to normative ranges in our database, to help highlight change in a measure over time.
Interday Data: In Interday Data, you get a calendar view of the current month and how many throws were made each day. The throws can be displayed as total throws, or just high effort throws. When selecting a specific day on the calendar, the throws from that day will appear on the graph to the left displayed in all 4 of the metrics, so that you can perform a throw-by-throw analysis. You can add or subtract the specific metrics from the graph by clicking on the metric icon above the graph. This graph is also another option for tagging throws. By highlighting a throw or a group of throws, you can select the specific tags based on what type of throw it was. The throws are also time-stamped to help identify the type of throw made. Designate pregame warmup routines by selecting group tagging the athlete's bullpen or long-toss routine, for use in GameDay workload simulations. Lastly, you can look at the throw metrics on the graph or in Fatigue Units. Fatigue Units are PULSE' newest measure of within-day workloads on the throwing arm. Fatigue Units capture the workload effect of rest intervals and throwing density within a training session.
Box Score Tag Analysis: Box Score Tag Analysis allows you to view metric averages by tag and sub-tag. You can look at averages for arm slot, arm speed, shoulder rotation, torque, ball velocity if entered, and workload units. You can also select Throw count to see how many throws are in the database for the athlete and how many have been tagged for throw type. If you hover over a cell, you'll see the sub-tag averages. Tag averages can be displayed for All Throws, or High Effort throws.
Day Reports - Day report creates a PDF of the Daily summary for the athlete in terms of current AC Ratio, Chronic WL, Acute WL, and Daily WL. Total throws and total High Effort Throws made today are given, as well as a graph of the amount of Elbow Valgus Torque for each throw made today.
Workload Reports - By selecting a date range, you can view an athlete's past workloads for those dates. On the top graph will be throw counts and the AC ratio, while the bottom graph displays the One Day Workload and Chronic WL.
GameDay Reports - Since game-day routines are quite consistent for a given pitcher, we require all users to capture a baseline Bullpen and Longtoss session in the PULSEthrow mobile app to use the Game Day report generator. Next, these known pregame workloads will be subtracted from a player's total game-day workload allotment. The workload remaining is the total work left for in-game throwing activity. Unlike a typical pitch count, this in-game Workload includes throws between innings and any other game activity that may occur. The final step is to convert the remaining in-game workload allotment into a "suggested pitch limit." This is done by dividing the remainder of Workload by your per-pitch Workload in the game-day bullpen session that was designated.
We can look at the conversion chart for today or tomorrow as well. Tomorrow's conversion chart will give the coach the ability to look at different one-day workloads to provide him with a sense of if the pitcher's Workload was any of those, what would the result be in terms of AC ratio and available in-game throws.
Besides an individual player view, Report Generator can also look at the entire team. The table shows a simulation of One-Day Workloads and the resulting A:C Ratio for each athlete. Cells outlined in Blue indicated a safe maximum One-Day Workload the athlete can perform today while maintaining an A:C Ratio below 1.3 and not increasing their Chronic Workload by more than 250% in a single day. One-Day Workloads are capped at 50 for all athletes. Athletes with no Chronic Workload are not considered and are grayed out. The table below shows how the safe maximum One-Day Workloads calculated on Page 1 convert to a Gameday throwing plan for each athlete. The athlete's pregame Bullpen and Longtoss workloads are subtracted from their allotted One-Day Workload and converted to an in-game throw count using the average torque of their bullpen throws. Only athletes who have designated Gameday Bullpen and Longtoss sessions in the PULSEthrow app can have throw counts calculated.
Program Builder: PULSEthrow continues to help streamline throwing workload management with it's newest addition to DASH, the Program Builder. The program builder now allows DASH users to build and send individualized Workload Programs. DASH workload builder module provides for the creation of long term training routines, with projected workload metrics and within-day training regimens based on the player's tagged data.
When using PULSEthrow, athletes and coaches can tag throws based on throw type. Tag options are Catch, Longtoss, Bullpen, Game, or they can create a custom tag. There are also sub-tags available for the distance, throw type (Fastball, Curveball, etc.), and weight of the ball. When throws are tagged, DASH creates a tag analysis to display how many workload units the athlete averages for each of the throw types. Now when the coach or athlete starts to build a throwing program, these averages are used to calculate Workload for each throw, which gets added up to calculate the total one-day Workload and what the resulting AC Ratio will be. It takes the guesswork out of designing throwing programs. As easy as dragging and dropping throw types or already built out throwing plans, players will have throwing plans sent to them through the app for it to be easily accessible.
Account: The Account page is where you can edit information such as your name, email address, change password, and team name. You can also add athletes to your roster either manually or by uploading a CSV file. If you need a CSV template, you can download one here, so that you can upload it later on. Subscriptions can also be managed here in the account. You'll see a history of your invoices and can set up email communication for updates on your athlete's workload.
Settings: The settings page plays a pivotal role in the prescription of Workload. First, an athlete or coach should enter the season that they're currently in. The choices are Pre-season, In-season, or Training mode. Each of these will help dictate the type of Workload or goals of the athletes. Once that is established, it'll ask a couple more questions. If Pre-season is selected, you'll be prompted to enter the date of opening day, so that we can adequately ramp the athletes up to be ready to go on opening day. Athletes will also be asked which days they're throwing and which days are game days or bullpen days. This information helps to try and optimize the player for these higher effort days.
Import Data: Import Trackman and Rapsodo Ball Flight Data. Drag and drop .csv files from ball-tracking technology. DASH will time-match data from either system to available sleeve data and will auto-tag all activities that are matched. Un-matched data is available for torque simulation when the sleeve is not worn.
