Relationship of body composition to somatotype

Area of Science:

• Anthropometry
• Human Biology
• Body Composition Analysis

Background:

• Somatotyping categorizes body shape.
• Two main methods exist: Sheldon's and Heath-Carter's.
• Understanding somatotype's relation to body composition is crucial.

Purpose of the Study:

• To investigate the relationship between somatotype and body composition in college-aged women.
• To compare Sheldon's and Heath-Carter's somatotyping procedures in relation to body composition.

Main Methods:

• Somatotype assessment using Sheldon's and Heath-Carter's methods.
• Body composition measurement via whole-body 40K counting and body density.
• Statistical analysis to determine relationships between somatotype components and body composition metrics.

Main Results:

• Sheldon's endomorphy correlated with height and weight.
• Heath-Carter's first component strongly related to weight and body fat.
• Lean body mass (LBM) showed limited association with Sheldon's mesomorphy or Heath-Carter's second component.
• LBM and height explained 61% of the variance in Heath-Carter's second component.
• Weight and height accounted for variations in Sheldon's ectomorphy and Heath-Carter's third component.

Conclusions:

• Heath-Carter's somatotype method demonstrates a closer relationship with body composition than Sheldon's method.
• Body composition significantly influences Heath-Carter's first and second somatotype components.
