Sports injuries are fundamentally a materials science problem. When a material is subjected to loads beyond its structural capacity, there is a disarrangement of components that diminishes its capacity until it reaches the breaking point of that particular material.

In the context of biology, this simplified concept becomes even more intricate. The capacity of biological materials depends on their structure, mechanisms of regeneration and rearrangement, as well as their physiology. It's not sufficient to merely understand the potential load a material can tolerate; it's equally crucial to comprehend how other mechanisms will come into play and interact in each specific case.

Two years ago, I shared an analysis of Erling Haaland's performance on LinkedIn. I highlighted various aspects that posed risks to his safety and could potentially jeopardize his promising professional career. As anticipated back then, he is currently sidelined from training and competition, likely due to reasons outlined in my previous report.

In my second report about Erling Haaland, published on my blog, I aim to present evidence supporting my hypothesis regarding the most probable causes for his current absence. While the public diagnosis mentions a "foot bone stress," my biomechanical analysis of his performance allows us to infer some possible injuries.

Erling Haaland serves as a compelling example of an injury prevention process that hasn't fully adapted to the current competitive demands of a soccer player. Injury prevention is a critical aspect of player development and training, commencing when a young prospect joins the academy and extending throughout their career. It's a daily, complex, multivariate numerical process that demands a solid scientific foundation to effectively mitigate risks.
