Sheldon's Method of Assessment of Human Physique
1. Introduction to Sheldon's Somatotyping:
William H. Sheldon, an American psychologist and physician, developed the concept of somatotyping in the 1940s as a method of classifying human physique based on three basic body types or somatotypes: endomorph, mesomorph, and ectomorph. Sheldon proposed that individuals could be characterized by the relative predominance of these three somatotypes, which are associated with different physical and psychological traits.
2. Components of Somatotyping:
Sheldon's somatotyping method involves assessing individuals based on three primary components:
a. Endomorphy: Endomorphy refers to the degree of relative adiposity or body fatness. Endomorphic individuals tend to have a rounder, softer physique with a higher percentage of body fat. Sheldon described endomorphs as having a relaxed, sociable temperament and a tendency towards comfort-seeking behaviors.
b. Mesomorphy: Mesomorphy relates to musculoskeletal robustness and muscularity. Mesomorphic individuals exhibit a lean, muscular build with well-defined musculature and low body fat percentage. Sheldon associated mesomorphy with traits such as assertiveness, competitiveness, and athleticism.
c. Ectomorphy: Ectomorphy refers to the degree of linearity or slimness of the physique. Ectomorphic individuals have a slender, elongated body shape with low body fat and minimal muscle mass. Sheldon characterized ectomorphs as introverted, sensitive, and intellectual, with a predisposition towards solitary activities.
3. Assessment Procedure:
Sheldon's somatotyping method involves a systematic assessment of individuals' physical characteristics to determine their relative somatotype. This assessment typically includes the following steps:
a. Anthropometric Measurements: Anthropometric measurements, such as height, weight, body circumferences, and skinfold thickness, are taken to quantify individuals' body composition and proportions.
b. Rating Scale: Each component of somatotyping (endomorphy, mesomorphy, ectomorphy) is rated on a scale from 1 to 7, with higher scores indicating greater expression of the respective somatotype. For example, an individual with a score of 7 for endomorphy would exhibit a high level of body fatness.
c. Calculation: The ratings for endomorphy, mesomorphy, and ectomorphy are combined to generate a three-digit somatotype rating. For instance, an individual classified as 3-7-2 would have a mesomorphic-dominant physique.
4. Application and Critique:
Sheldon's somatotyping method has been widely used in anthropology, sports science, and psychology to study the relationship between physique and behavior. It has been applied in diverse contexts, including sports talent identification, criminal profiling, and personality assessment.
However, Sheldon's somatotyping method has also faced criticism for its subjectivity, lack of reliability, and oversimplification of human diversity. Critics argue that somatotyping relies heavily on visual assessment and subjective judgment, leading to inconsistencies and biases in classification. Moreover, the rigid categorization of individuals into discrete somatotypes overlooks the continuous variation in human physique and fails to account for the influence of environmental factors on body composition.
5. Contemporary Perspectives:
Contemporary research in somatotyping has shifted towards more objective and quantitative methods of assessing body composition, such as dual-energy X-ray absorptiometry (DEXA) and bioelectrical impedance analysis (BIA). These techniques offer precise measurements of body fat, muscle mass, and bone density, allowing for a more accurate assessment of physique.
Conclusion:
Sheldon's somatotyping method provides a framework for categorizing human physique based on three primary components: endomorphy, mesomorphy, and ectomorphy. While the method has been influential in anthropology and related fields, it has also been criticized for its subjectivity and oversimplification. Contemporary research continues to explore new approaches to assessing body composition and understanding the complex relationship between physique and behavior.
