fitness_tools.composition.bodyfat module

class fitness_tools.composition.bodyfat.DurninWomersley(age, sex, *args)

Bases: fitness_tools.composition.bodyfat.GenericCalculator

Uses the Durnin Wormersley equation to calculate body density. Use triceps, biceps, subscapular, and suprailliac skinfold measurements.

Parameters:
  • age – Age as a positive, whole number
  • sex – Sex either ‘male’ or ‘female’ case insensative.
  • *args –

    A list of positive, whole numbers reflected as skinfold measurements in millimeters.
body_density()

Converts params age, sex, and skinfolds to body density.

Return type:float
Returns:body_density
class fitness_tools.composition.bodyfat.GenericCalculator(age, sex, *args)

Bases: object

The base class that all body fat calculations inherit from.

Parameters:
