How the "center of gravity" shifts from Speed toward Endurance as event distance increases. Four overlapping bell curves show the capacity profile for the 800m, 1600m, 3200m, and 5K.
The PTG as diagnostic X-ray. See how "full" each training zone is for real athletes — from Emanuel's resistant grinder profile to Niamh's speed-without-transfer signature.
How capacity profiles evolve across a four-year high school career. Track ratio changes for three real athletes and see what development — and injury — look like in the data.
