Athlete Metrics

Analyzing training sessions with athlete's performance and session metrics.

A. Athlete's Performance Metrics

Total Distance: 

A key marker for volume, total distance is the full distance traveled in meters/yards (at all speeds) for the duration of the performance or segment/s.

Work Rate:

A key marker of performance intensity. 

The total distance covered (m/y) relative to time (min) will demonstrate the relative physical demands of a performance or segment/s.

Hard Running Distance:

When an athlete is travelling at a speed greater than 4.5m/s (or as defined in your settings) this is classified as hard running. 

Hard Running Distance is the total volume accumulated above this speed.

*Given the more intense nature of hard running, there is a need to measure and monitor to ensure athlete fatigue levels can be identified.*

Hard Running Rate (HaRun/min):

Meters/yards covered per minute at a speed greater than 4.5m/s (or as defined in your settings) during a performance or segment/s.

Hard Running Efforts:

An athlete must maintain the hard running threshold of 4.5 m/s (or as defined in your settings) for longer than 1 second to register a hard running effort.

The ability to repeat hard running efforts can be a strong determinant of high level athletic performance.

Sprint Distance:

When an athlete is travelling at a speed greater than that defined in your settings (default 6m/s) this is classified as sprint distance. 

Exposing athletes to high speeds regularly is important to minimize the chances of soft tissue injuries occurring.

Sprint Distance Rate (Sprint/min):

Meters/yards covered per minute at a speed greater than 6m/s (or as defined in your settings) during a performance or segment/s.

Sprint Efforts:

The number of times throughout the duration of the performance that an athlete breaks a velocity of 6m/s (or as defined in your settings) and maintains that speed for longer than 1 second.

Regular exposure to sprint efforts is an important factor to consider when designing training sessions. Ensuring athletes are subjected to regular sprint efforts will decrease the likelihood of soft tissue injuries occurring at high speeds.

Top Speed:

The maximum speed an athlete reaches at any stage throughout the performance. 

Demonstrates what an athlete is capable of, this in turn will help you build out their athletic profile.

Exertion Index (Intensity):

A single number that incorporates the distance, speed and duration of an athletes high velocity efforts, Efforts that register a greater speed and duration are given a higher weighting.

 

B. Session Metrics

2D Load:

A summation of the horizontal forces (forwards & backwards, left & right) your body is subjected to throughout the course of the performance.

3D Load:

A summation of all horizontal (forwards & backwards, left & right) and vertical forces (up & down) your body is subjected to throughout the course of the performance.    

Impacts:

An impact is classified as a change in acceleration (measured by the IMU) of greater than 5.5 g-force.

A rapid change in acceleration (5.5g) in less than 0.1s will likely occur during impact with the body*.

Heart Rate Zones (HR):

Please follow this link to an in-depth article on heart rate training zones.

Average Heart Rate: 

The average Beats Per Minute (BPM) recorded for the duration of the performance.

Max Heart Rate:

The maximum Beats Per Minute (BPM) recorded for the duration of the performance.

This metric is different to your 'estimated maximum heart rate'. 

Max Heart Rate is the maximum BPM from the specific performance you are looking at.

Percent Red Zone:

The total percentage of time spent at above 90% of the estimated maximum heart rate.

Time in Red Zone represents the most intense periods of training or match play. The greater an athletes ability to tolerate these intense periods, the better prepared they will be for the demands of competition. 

Efficiency Index:

The relationship between external load (work rate) and internal load (heart rate).

- An athlete that has a low average heart rate (BPM) and covers a large running volume (meters) will have a greater Efficiency Index. 

- An athlete that has a higher average heart rate (BPM) whilst covering low volume of running (meters) will have a lower Efficiency Index.
