A new statistical approach to training load and injury risk: Separating the acute from the chronic load
Bache-Mathiesen, Lena Kristin; Andersen, Thor Einar; Dalen-Lorentsen, Torstein; Tabben, Montassar; Chamari, Karim; Clarsen, Benjamin Matthew; Fagerland, Morten (Peer reviewed; Journal article, 2024)The relationship between recent (acute) training load relative to long-term (chronic) training load may be associated with sports injury risk. We explored the potential for modelling acute and chronic loads separately to ... -
