|
Lean body mass |
Small percentage of non sex specific fat equivalent to 4-7% of body mass |
|
|
Essential fat |
Fat in heart, lungs, liver, spleen, kidneys, intestines, and sex specific fat in females |
|
|
Storage fat |
Fat packed primarily in adipose tissue. Includes visceral fat that protect various internal organs and subcutaneous fat |
|
|
Minimum fat requirements for men and women |
Men: 3% Women: 12% |
|
|
Average body fat percentages |
Men: 15% Women: 27% |
|
|
Hydrostatic weighing |
Objects loss of weight in the water equals the weight of the volume of water it displaces. It's based on gender averages which can vary. The constant for density values for children and aging adults introduces errors. There are many errors in measuring RLV |
|
|
BOD POD |
body volume equals the chambers reduced air volume. Uses displaced air to measure body fat. It's very fast, but the things are very expensive |
|
|
Skinfold measurement |
Based off relationships between subcutaneous fat and internal fat. Most commonly uses 7 sites. Can measure body fat and really good with pre and post tests. Easy and portable method |
|
|
Girth measurements |
Can measure changes in Fat, but not great at predicting levels of fatness. Easy, but doesn't say that much |
|
|
Bioelectrical impedance |
Two electrodes move faster through fat free mass, it measures how long it takes them to move. Water has a great effect on these so levels of hydration need to be constant. Overpredicts fat in lean and underpredicts fat in obese. Not accurate |
|
|
Dual energy xray DXA |
Quantifies fat and muscle around bony areas of body including regions without bone. Does not rely on assumptions. Very accurate, just not practical. At all. |
