Has the athlete trained enough to return to play safely? The acute:chronic workload ratio permits clinicians to quantify a player's risk of subsequent injury

What this work gives Aellic

The actual origin of the four-week chronic window Aellic computes against: injury likelihood is modelled against “acute load spikes above what they have been doing on average over the past 4 weeks (chronic load)”, with a polynomial fit of R² = 0.53 across three sports. Also the source of the sweet-spot figure that gabbett2016 reproduces.
