      Lesson details

      Learning outcome

      I can identify and describe the characteristics of ectomorph, mesomorph and endomorph body types.

      Key learning points

      1. An endomorph is characterised by a higher percentage of body fat and a rounder body shape
      2. A mesomorph has a muscular and well-defined body with a natural ability to gain muscle
      3. An ectomorph is characterised by a slim, lean physique with minimal body fat and muscle
      4. Each somatotype has specific advantages for different types of sports or positions.

      Keywords

      • Somatotype - a method of classifying body type

      • Ectomorph - a somatotype characterised by being tall and thin with narrow shoulders and narrow hips

      • Mesomorph - a somatotype, characterised by a muscular appearance with wide shoulders and narrow hips

      • Endomorph - a somatotype, characterised by a pear shaped body/fatness with wide hips and narrow shoulders

      • Body composition - the percentage of body weight which is fat and nonfat (muscle and bone)

      Common misconception

      Believing that individuals fit exclusively into one somatotype category rather than having a mix of characteristics.

      Individuals can have a mix of characteristics from different somatotypes but can also change their somatotype depending on their lifestyle choices.

      Teacher tip

      Pupils may be asked to justify why different somatotypes are beneficial to different sports.
