Elite sport now collects more data than any staff can use. The discipline that separates useful programmes from noisy ones is deciding in advance which measurements will change a decision.
Thermoregulation is a hard constraint rather than a matter of toughness. The body will protect its core temperature even when that means refusing to produce the effort an athlete is asking for.
Two athletes with an identical scan can follow entirely different paths. The variation sits in tissue quality, sport demands and the environment around the athlete rather than in the injury itself.
Subjective readiness and physiological readiness diverge routinely, and the direction of the error is not random. Understanding why explains a large share of avoidable setbacks.
Training does not make an athlete fitter while it is happening. The adaptation is assembled afterwards, and most of the interesting work happens when nobody is watching.
