Table 2 Overview of additional training load metrics calculated from the raw parameters (session duration and RPE) in the training load reports.
From: A large-scale multivariate soccer athlete health, performance, and position monitoring dataset
Metric | Description | Formula |
|---|---|---|
Session RPE (sRPE) | The workload for a single session based on the session duration and the reported RPE | RPE·duration |
(Daily) Training Load | The sum of sRPE for a day | \(\sum sRPE\) per day |
Weekly Load (WL) | The sum of sRPE over the last 7 days | \(\sum sRPE\) per week |
Acute Training Load (ATL) | The current level of fatigue (average sRPE over the last 7 days) | \({7}^{-1}{\sum }_{n=i}^{i+7}D{L}_{i}\) |
Chronic Training Load (CTL) | The cumulative training dose that builds up over a longer period of time (average sRPE over the last 28 or 42 days) | \({x}^{-1}{\sum }_{n=i}^{i+x}D{L}_{i},\;\;{\rm{x}}=28\;{\rm{or}}\;42\) |
Acute Chronic Workload Ratio (ACWR) | An indication of whether an athlete is in a well-prepared state, or at an increased risk of getting injured (ATL divided by CTL) | ATL·CTL−1 |
Monotony | Training variation across the last 7 days (average sRPE over the last 7 days divided by the standard deviation (SD)) | ATL·SD−1 |
Strain | Overall training stress from the last 7 days (total weekly sRPE multiplied with Monotony) | WL·Monotony |
