Lean body mass plus body fat equals body weight. LBM differs from FFM in that cellular membranes are included in LBM although this is only a small percent difference in the body's mass (up to 3% in men and 5% in women) [1] The percentage of total body mass that is lean is usually not quoted – it would typically be 60–90%.
Fat-free mass (muscle) is a good conductor as it contains a large amount of water (approximately 73%) and electrolytes, while fat is anhydrous and a poor conductor of electric current. Factors that affect the accuracy and precision of this method include instrumentation, subject factors, technician skill, and the prediction equation formulated ...
These factors result in women's waist–hip ratio (WHR) being lower than for males, although males tend to have a greater upper-body to waist–hip ratio (WHR) giving them a V shape look because of their greater muscle mass (e.g., they generally have much larger, more muscular and broader shoulders, pectoral muscles, teres major muscles and ...
BMI. BMI measures a person’s weight compared to their height. It’s a simple division equation. Since it’s such a quick and easy way to get a rough idea of whether you have a healthy weight ...
After menopause, if you aren't doing anything to at least maintain your muscle mass, you are getting weaker faster. If you want to pick up a grandchild at 65 or 70, you had better be able to bicep ...
Women with a relatively low waist-hip ratio (the hourglass figure) is commonly considered attractive. To enhance their perceived attractiveness, some women may artificially alter their apparent WHR. The methods include the use of a corset to reduce the waist size and hip and buttock padding to increase the apparent size of the hips and buttocks.
Compared to traditional metrics, such as the body mass index (BMI), (which uses weight and height), BRI may improve predictions of the amount of body fat and the volume of visceral adipose tissue. Despite its common use, BMI can misclassify individuals as obese because it does not distinguish between a person's lean body mass and fat mass ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).
