The pitfalls of body fat measurement. Even the best techniques have a 4 5 error rate when measuring change over time. There are several techniques you could use to measure body fat. However the convienience of this method comes at a price of accuracy. Bod pod the pitfalls of body fat measurement part 5. The pitfalls of body fat measurement part 3. Also the cdc says.
In part 1 of this series you learned about how body fat testing is a prediction not a measurement. This means to accurately detect a decrease in body fat in most people the body fat percentage needs to drop by a minimum of 4 5. On average underwater weighing underpredicts meaning it gives you lower body fat percentages than a 4 compartment model body fat percentage by 01 to 12 although one study showed an overprediction in young women of 21. Skinfolds the pitfalls of body fat measurement part 6. Disadvantages of bmi testing your body weight includes a number of components such as muscle mass fat internal organs water and skeletal weight. The lower your body fat percentage the higher percentage of lean muscle mass you have on your frame.

Body composition testing or body fat testing measures the amount of body fat and fat free mass also referred to as lean tissue muscle mass body water bone and organs in the body. Skinfolds the pitfalls of body fat measurement part 6. In part 2 you learned about underwater weighing and in part 3 you learned about the bod pod. Given the error rate for measuring change over time theres a good chance those numbers are way off. So an athlete with a lot of muscle for example could have a higher bmi based on their weight and height. Experts rate the best and worst in body fat measurement devices.
The downside to relying on bmi is that it doesnt measure body fat. Dual energy x ray absorptiometry dexa the pitfalls of body fat measurement the final chapter.
