Rating of perceived exertion
The Borg scale (RPE) and session load.
In football, the Borg scale shows up as the 0 to 10 rating of perceived exertion (RPE), given after training or a match. Multiplied by the minutes, it becomes session load.
The scale in StatsCenter
From 0 to 10, with both ends named.
It is the scale of the product's questionnaires: 0 is rest and 10 is maximal. The numbers in between carry no name in StatsCenter.
How the questionnaire asks
- Post-trainingHow hard was the session?
- RPEHow hard was today's training?Training duration (minutes)
Where RPE comes in
- Training: each athlete's RPE arrives with the session data, beside the GPS, and the minutes are those of their participation.
- Matches: the RPE and the minutes on the pitch of each athlete who played.
- Questionnaires: the Post-training and RPE templates ask the squad the question. The answers stay with the questionnaires; load is calculated from the RPE recorded with the session and the match.
Session load
RPE times minutes, in arbitrary units.
Each athlete's session load is the RPE they gave multiplied by their minutes of participation in that session. A match is read the same way, with the minutes on the pitch.
The formula
Session load (AU) = RPE × minutes of participation
When the RPE or the minutes are missing, the session stays out of the sum and is counted apart, as a session without a record; StatsCenter never fills it in with zero.
Result
Over the days
What StatsCenter calculates from the load.
The calculations read the days that are over: both windows end the day before. None of them comes with a band, a colour or a classification; what each number means is the club's reading.
- Acute load
- Sum of the load over the last 7 days
- Chronic weekly load
- Sum of the load over the last 28 days ÷ 4
- Acute:chronic workload ratio (ACWR)
- Acute load ÷ chronic weekly load
- Monotony
- Mean daily load over the last 7 days ÷ the standard deviation of that load
- Strain
- Acute load × monotony
A day without a record leaves the calculations at ND (not available), with a count of what is missing. A day with no training and no match is rest and counts as zero.
