dataMarq Report Definition

The basketball load dashboard provides a comprehensive view of the catapult load data. 

The report includes multiple pages of data, broken down by different longitudinal views.

Load Overview

A single day and weekly view of load data for a selected season.  The top half of the page is a single day view, with the bottom half of the page providing the weekly overview

Weekly Load by Type

Basketball loads are broken into the type of activity. Types include:

• Practice
• Shoot Around
• Extra Work
• Game Warm Up
• Game
• Conditioning

Season Load by Type

A season long view of load by types and percentages.  The page includes a data slicer so specific time periods can be analyzed.

Intensity by Type

A breakdown of intensity levels by different types of activities. Intensity metrics include:

• Average Load
• Explosive Ratio
• High Player Load
• Violent Efforts
• Sprint Distance Ratio
• Sprint Distance per Minute

Individual and Team Load Projections

These are load projections based on historical load numbers of a given player and a given day.  The projection formula is straightforward, and takes into account the day type relative to the last game and next game.  Load for specific day types (1 day post game, 2 days pre game,  more than 3 days pre or post, etc.)  are average and used as the projected number.  These averages are then used for the group of athletes selected to get team averages.

Practice Detail

A breakdown of load in practice compared to load activities in game.  Practice activities are taken from the name of the practice period and intensity and volume metrics are compared to average game metrics to analyze the "game like" nature of different practice sessions.

Explosive effort is an intensity metric using catapult's activity sensors that is based on IMA (Intertial Movement Analysis - see below). 
Explosive effort is often used to calculate explosive ratio, whish is the ratio of high intensity movements to the total player load for a given training period and can be used to approximate how an intense a session was for a specific player.
Inertial Movement Analysis (IMA) is a set of metrics that measures athlete micro movements and direction regardless of unit orientation. Athlete movements can be quantified into low, medium and high intensity athlete movements zones that are used to construct profiles of athletes movements and to recognize biomechanical red flags. 
IMA gives indoor and outdoor sports the ability to track:

• Acceleration count
• Deceleration count
• Asymmetrical loading
• Change of direction (COD) count - left and right
• Free running event count
• Free running total time
• Average stride rate
• Impacts
• Jump count
• 
  

A measure of the total amount of distance covered at a high intensity. This is slightly different than sprint distance.
High Intensity Distance = velocity_band6_total_distance + velocity_band7_total_distance + velocity_band8_total_distanceSprint Distance = velocity_band5_total_distance + velocity_band6_total_distance + velocity_band7_total_distance

High player load is player load that happens in the 3rd to 8th bands of exertion.  Bands are 'Zones' set to each athlete for specific Metrics. These Bands allow for a more detailed breakdown and analysis of certain metrics such as Velocity, Acceleration and Player Load, etc.

This parameter tells you how much work the player did during a training session or game. It is a volume measure. The number itself is an arbitrary unit, meaning it is to be used as a scaling factor to compare the total volume of work performed.
For example, a player that has a Total Player Load of 300 did 50% more work than a player that has a Total Player Load of 200. This number is best used to evaluate how much work a specific player has done over time or to compare how much work that player did in a specific training session compared to previous sessions.
It has advantages over using distance as an effort metric because it accumulates non-running activities. However for an athlete whose main activity is running, there will be a strong correlation between distance covered a nd Player Load. 

Projected load is a calculated statistics based on historical averages for a given athlete.  To determine the projection the following steps are taken:

1. Categorize each day of the season in a specific "day type"
1. >= 3 day pre/post game
2. 3 days pre game / 1 day post game
3. 3 days pre game / 2 days post game
4. 2 days pre game / 3 days post game
5. 2 days pre game / 2 days post game
6. 2 days pre game / 1 day post game
7. 1 day pre game / 3 days post game
8. 1 day pre game / 2 days post game
9. 1 day pre game / 1 day post game
10. Game day
2. Averages are calculated for each of the day types for every player based on rolling 45 day windows
3. Future projected daily loads are based on the latest average for that day type

The load TSB is a calculation of the ratio of acute load to chronic load for a given athlete.  This metric helps to approximate potential fatigue and possibility for injury.  TSB can be calculated for a day or for a week.  
Daily TSBThe daily TSB formula is as follows:

• Average Load for Last 7 Days (Acute Load) / Average Load for Last 21 Days (Chronic Load)

• Total Load for Last Week (Acute Load) / Average Weekly Load for Last 3 Weeks (Chronic Load)

A catapult metric based on effort counts within acceleration bands.  The specific formula is:
gen2_acceleration_band7_total_effort_count + gen2_acceleration_band8_total_effort_count
