WHAT IS THE PROJECT ABOUT:
Sudden increase in training load has been linked to increased risk of injuries and illnesses (health problems). In the past years, researchers have claimed that easy-to-use calculations can precisely estimate how much training load can increase without increasing the risk of health problems. In this PhD-project, we found that it’s not possible to assess risk of health problems based on training load, and that the studies claiming this has substantial methodological weaknesses. Moreover, we found that using an one-size-fits-all approach of training load management did not reduce the risk of health problems among almost 500 elite-youth footballers of both sexes.
Despite a lack of models accurately estimating risk based on training load and lack of evidence for its preventive effect, we should still use training load management. Without more complex models, we should lean on the basic training principles and follow an even progression of training load that is based on the coaches’ experience and the players’ need.
This PhD-project also investigated whether the match congested 2020 Norwegian premier league (Eliteserien) had different injury characteristics compared to the normal 2019-season. We found no differences and concluded that a match congested season like the 2020-season can be a safe alternative.
