LBM |
Lean body mass Composed of muscles, connective tissue, bones, blood, nervous tissue, skin, organs |
|
|
Essential body fat for M/W |
Men: 2-5% Women: 10-13% |
|
|
Hydrostatic weighing |
Underwater weighing, benchmark for measuring body comp, Density=mass/volume |
|
|
Skinfold measurements |
Measures subcutaneous body fat, Accurate +/- 2-3.5% of hydrostatic weighing, Use 3 sites on body for measurements |
|
|
Skinfold measurement sites for men |
|
|
|
Skinfold measurement sites for women |
|
|
|
Describe the protocol for skinfold measurements |
1. measurements should be taken on R side of body while standing 2. pinch the skin in the correct site and measure to the nearest 0.5 mm 3. each site should be measured at lease twice (3 times if there is a large disparity between measurements - then take the average of the two closest scores) |

|
steps to calculate goal weight to reach desired body fat % |
1. 100% - current body fat % = lean mass % 2. current body weight(lean mass %) = current lean mass 3. 100% - desired body fat % = desired lean mass % 4. current lean mass / desired lean body mass % = desired body weight page 206 |

|
BMI |
Body Mass Index - ratio describing relationship between weight & height - cannot determine body composition, so is inaccurate to use in some populations BMI = weight (lb) / height (in) x 703 |
|
|
reasons why exercising is is key to maintaining a healthy weight/body composition |
- exercise increases daily caloric expenditure - exercise, especially strength training, minimizes the loss of lean body weight - exercise may suppress appetite and counteract the impact that diet may have on resting metabolic rate (RMR) - Exercise makes the body more efficient at burning fat |
|
|
WHR |
Waist to Hip Ratio WHR = waist measurement / hip measurement helps differentiate individuals that are apple-shaped from those that are pear-shaped |
|
|
VO2max |
maximal oxygen uptake - estimation of body's ability to use oxygen for energy - closely related to functional capacity of heart - measures cardio efficiency |
