The fixture list injures players and the training ground takes the blame

Sports science departments are held responsible for a workload calendar that nobody in the building controls.

A hamstring goes in the seventieth minute of a Wednesday match, and by Thursday morning somebody is asking whether the sessions were too heavy. Almost always the wrong question.

What a club actually controls is a shrinking fraction of a player's year. Match minutes are fixed by competition. Travel is fixed by fixture. International windows take players out of the building entirely, hand them to a staff with different methods and a different agenda, and return them the day before a league game having flown eleven hours in economy comfort at best. Add a summer tournament and the off season becomes eleven days. Inside all of that, the training ground is asked to manage load, and the only variable it can move is the one thing that keeps players durable, which is training.

So you get the paradox that everyone in performance work recognises. The response to congestion is to reduce training, and reduced training reduces the tissue capacity that congestion demands. Players end the season having played more and prepared less. The chronic base falls, the acute spikes stay, and the ratio between them is precisely the thing that predicts soft tissue injury.

Travel deserves more attention than it gets. It is not merely fatigue. Long flights disrupt sleep architecture, and sleep is where the adaptation from training and the repair from matches happen. A squad crossing time zones twice in ten days is not tired in the way a hard session makes you tired. It is under-recovered in a way no session ever caused, and no amount of clever periodisation on the grass fixes it.

My view is that the sports science department has been handed accountability without authority, which is the classic setup for being blamed. If the calendar is set by competition organisers and broadcasters, then the injury numbers belong to competition organisers and broadcasters, and they should be published against them.

Until that happens, clubs will keep hiring another physiologist after a bad injury season, which is roughly like hiring a better mechanic because the road is full of holes.
