Revision summary
Somatotype rates roundness, muscularity, and linearity. Sheldon began with photos; Heath and Carter used anthropometry. Skinfolds feed endomorphy; bone and girth feed mesomorphy; ponderal index feeds ectomorphy. Scores are written as three numbers on a somatochart. Use it for sport and growth, not for temperament.

Introduction
An anthropometric somatotype is a three-number rating of physique from body measurements. Heath and Carter made Sheldon’s idea operational without photographs as the main tool.
Body
Somatotype as an idea
- Sheldon scored endomorphy (roundness), mesomorphy (musculo-skeletal robustness), and ectomorphy (linearity) from photos.
- The method was criticised as subjective and politically misused. Sport and growth studies still needed a body-shape index.
Heath–Carter method
- Barbara Heath and J. E. L. Carter published equations using height, weight, skinfolds (triceps, subscapular, supraspinale, medial calf), biepicondylar humerus and femur, and flexed arm and calf girths corrected for skinfold.
- Endomorphy comes mainly from the three skinfolds, adjusted for height.
- Mesomorphy uses bone breadths and corrected girths against height.
- Ectomorphy uses the ponderal index (height over cube root of weight).
- The result is written as X–Y–Z, for example 2–5–3, and plotted on a somatochart.
Use and critique
- Sports anthropology in India uses it to compare throwers, distance runners, and controls.
- It is a phenotype now, not a temperament. Sheldon’s psychiatric claims are dropped.
- Limits: operator error on skinfolds, age and fat change, and the fact that a number is not a destiny.

Conclusion
Heath–Carter somatotype is a measured endomorphy–mesomorphy–ectomorphy triad. It replaced photo-guessing with girth, bone, fold, and ponderal index, and it belongs in kinanthropometry, not in characterology.

Students also ask
-
Is somatotype genetic?
It has a heritable component, but training and fatness move the score.
-
Why not use BMI alone?
BMI ignores bone and muscle distribution. Somatotype splits fat, musculo-skeleton, and linearity.

More from this topic
Q2(a) · UPSC Mains 2026 · Anthropology GS 1 · 20 marks · Solution
What is meant by a somatotype? Discuss the Heath-Carter anthropometric method, giving its advantages over that of Sheldon's method. How can somatotyping be applied in sports sciences?
Ageing and senescence. Theories and observations
Somatotyping quantifies human body shape and composition into endomorphy, mesomorphy, and ectomorphy components. While Sheldon used visual ratings and photography with rigid whole-number scales, the Heath-Carter method uses anthropometric measurements like skinfolds, girths, and breadths, allowing continuous ratings and statistical analysis. In sports sciences, somatotyping aids talent identification, position allocation, and training optimisation by matching specific body builds with biomechanical demands of different disciplines.

Ageing and senescence. Theories and observations
Sheldon’s photoscopic somatotype depended on nude pictures and rater eye. Heath and Carter used skinfolds, girths, bone breadths, height, and weight. Three components are calculated, not guessed from a print. The method fits sports and growth surveys. It describes present shape, not race or temperament.

Discuss the physiological and evolutionary theories of aging
Ageing and senescence. Theories and observations
Physiological theories include oxidative damage, telomeres, and endocrine decline. Hayflick limits and repair failure describe cells, not purpose. Medawar: late harmful mutations accumulate. Williams: genes good early can be bad late. Kirkwood: the soma is disposable once reproduction is served.
