Which body type classification is identified as athletic?

The classification identified as athletic is mesomorph. This body type is characterized by a muscular and well-proportioned physique, with broad shoulders and a narrow waist, which is often associated with physical strength and agility. Mesomorphs typically have a natural advantage in sports and physical activities because of their ability to gain muscle mass easily and maintain an efficient metabolism.

Ectomorphs, on the other hand, tend to have a slim, lean physique with less muscle and body fat, making them less associated with athleticism compared to mesomorphs. Endomorphs usually have a rounder body shape with a higher proportion of body fat, which can also be a disadvantage in many athletic pursuits. The term "thin" does not define a specific body type classification in this context, and it is not representative of an athletic build.
