endomorphology
Endomorphology is a term used within somatotyping, a discredited theory that attempts to classify people into body types. The endomorph body type is characterized by a higher proportion of body fat, a rounder physique, and a tendency to gain weight easily. Individuals categorized as endomorphs are often described as having a soft, less muscular build. This body type is thought to be associated with a slower metabolism and a predisposition to storing energy as fat. The concept of endomorphology, along with mesomorphology and ectomorphology, was developed by William H. Sheldon in the 1940s. Sheldon proposed that these three somatotypes were linked to behavioral tendencies and personality traits. However, the scientific community has largely rejected somatotyping due to a lack of empirical evidence and the oversimplification of human physical and psychological diversity. Modern understanding of body composition and genetics recognizes a far more complex interplay of factors than these rigid categories allow. Therefore, while the term endomorph may still be encountered in some popular or historical contexts, it is not considered a valid scientific classification in contemporary biology or psychology.
