Study Notes
Body Composition Analysis Methods
- Body composition analysis calculates body fat percentage, fat-free mass, and target body weight.
- Bod Pod, using air displacement, measures body volume and density based on Boyle's Law.
- Factors affecting accurate Bod Pod results include body hair, clothing, and breathing patterns.
- Errors in Bod Pod testing can occur due to deviations in normal breathing and calibration.
- Advantages of Bod Pod include quick administration and minimal client compliance, but it is expensive.
- Dual-Energy X-Ray Absorptiometry (DEXA) assesses bone mass, fat, and lean soft tissue at whole-body and regional levels.
- DEXA uses low-energy x-ray beams to quantify bone mineral content, total fat mass, and fat-free mass.
- Advantages of DEXA include safety, rapid administration, minimal client cooperation, and accounting for individual variability in bone mineral content.
- Fasting prior to a DEXA scan increases accuracy, and calibration of the scanner is crucial for precise results.
- Variability among DEXA technologies, including imaging geometry, X-ray detectors, and software versions, affects accuracy.
- DEXA is expensive and generally accessible only in clinical or research settings.
- Both Bod Pod and DEXA have advantages and disadvantages in accurately assessing body composition.
