Maturation Assessment

Predict timing of growth to identifying windows of accelerated adaptation, during which the developing body responds best to speed, stamina and strength training, for short term fitness, individualised coaching and long term athletic development.

Sports Science to Advance Player Welfare

We interpret Player Welfare as additionally applying tried and tested algorithms and analytics from Sports Science to data captured during the course of coordinating team activities and communications, presented in a clear, visual graphic. Key published papers for measures implemented in SURPASSPORT are listed below.

Workload Score

Known formally as "Acute : Chronic Workload Ratio" (A:CWR), this measure is used by elite teams to measure the consistency of activity. It is calculated from Arbitrary Units ("AU"s) of workload and compares such values for the current period when compared to the average over the preceding number of periods.

SURPASSPORT uses a measure of Activity Duration by Intensity, averaged over 7 days and compared to an Exponentially Weighted Moving Average over the preceding 30 days.

Maturation & Growth Timing

Known formally as the age of "Peak Height Velocity" (aPHV), this is the age of the individual when their body is growing the fastest, often referred to as their growth spurt during teenage years. It is calculated based on skeletal measurements including standing height; torso height and body weight.

SURPASSPORT also records arm span and knee height in preparation of additional confirmation of the age of peak height velocity.

Subjective Wellbeing

Subjective Wellbeing is a relatively new approach to the assessment of individual well-being in a sporting context and provide additional insight into a team or individual's readiness for competition. It is captured using a daily prompt offering a 5-point scale on each metric monitored.
