Study Notes
Body Composition
- Body composition describes the proportion of fat, bone, muscle, water, protein, minerals, and other components in the body.
- It offers a more accurate health assessment than BMI, considering the various components.
Body Composition Components
- Water: Present in fat, muscles, blood, and bodily fluids.
- Protein: Found in muscles, organs, and bones.
- Minerals: Primarily located in the bloodstream and bones.
- Fat: Stored energy, protects organs, insulates, and regulates temperature.
- Fat Mass (FM): Fat used for energy storage, organ protection, insulation, and temperature regulation.
- Fat-Free Mass (FFM): Includes organs, muscle, and water.
Maintaining Body Composition
- Maintaining a healthy body fat percentage is crucial for long-term health. Excessive levels in either direction are generally undesirable.
Measuring Body Composition
Methods of Measuring Body Composition
-
Skin Calipers:
- Pros: Affordable, portable.
- Cons: Requires expertise, best for lean individuals, uncomfortable.
-
Digital Image Analysis App:
- Pros: Simple, readily available, inexpensive.
- Cons: Questionable accuracy.
-
Dual Energy X-Ray Absorptiometry (DEXA) Scan:
- Pros: Highly accurate, provides segmented body composition analysis.
- Cons: Requires a lab visit, expensive.
-
Bioelectrical Impedance Analysis (BIA):
- Pros: Easy, affordable, self-operated.
- Cons: Affected by hydration levels.
- Hydrostatic Weighing (HW): (Potential method)
- Computed Tomography (CT) and Magnetic Resonance Imaging (MRI): (Potential methods)
- BOD PODS (Air Displacement Plethysmography): (Potential method)
Visceral Fat
- Visceral fat, located around the midsection/trunk, is positively correlated with obesity-related diseases like cardiovascular disease, diabetes, and high blood pressure.
