Body Mass Index (BMI)
+ + + + + + + + + + + + + + + +
The BMI is an attempt to quantify the amount of tissue mass(muscle,fat, and bone) in an individual, and then categorize thatperson asunderweight, normal weight, overweight, or obese based onthatvalue. However, there is some debate about where on the BMIscalethe dividing lines between categories should be placed.Commonlyaccepted BMI ranges are underweight: under 18.5, normalweight: 18.5to 25, overweight: 25 to 30, obese: over 30.

Basal Metabolic Rate (BMR)
+ + + + + + + + + + + + + + + +
Basal metabolic rate (BMR) is the minimal rate of energyexpenditureper unit time by endothermic animals at rest. It isreported inenergy units per unit time ranging from watt(Joule/second) to mlO2/min or Joule per hour per kg body massJ/(h.kg)). Propermeasurement requires a strict set of criteria bemet. These criteriainclude being in a physically andpsychologically undisturbed state,in a thermally neutralenvironment, while in the post-absorptivestate (i.e., not activelydigesting food).

Body Fast Percentage (BFP)
+ + + + + + + + + + + + + + + +
The body fat percentage (BFP) of a human or other living beingisthe total mass of fat divided by total body mass; body fatincludesessential body fat and storage body fat. Essential body fatisnecessary to maintain life and reproductive functions.Thepercentage of essential body fat for women is greater than thatformen, due to the demands of childbearing and otherhormonalfunctions. The percentage of essential fat is 3–5% in men,and8–12% in women (referenced through NASM).
