Evaluation and Testing Calculations

 On your own paper:  Write out each equation  Find the answer for the practice scenario

BMI  BMI = Weight (kg)/Height 2 (m)  Lbs to kg, divide by 2.2  Inches to meters, multiply inches by 0.0254  Ex: 200lbs and stands 5/10”  Weight = 200lbs/2.2 = 90.9kg  Height = 70 inches. 0.0254 = 1.778 m  BMI = 90.1 / 1.778 2 = 28.7  Your turn:  Find BMI for a client who weighs 132 lbs and stands 5’7”

Body composition and goal weight (desired weight)  knowing how to calculate body composition can help determine desired (goal) body density (weight) This is assuming that Lean mass will not be changing throughout the program.  If you know the body fat % you will be able to determine goal weight.  Example: a female client’s current weight is 168 lbs, with 28% body fat.  Goal: to achieve 24% body fat without losing lean mass.  determine fat weight in lbs: BW x body fat % 168 lbs x 28% = 47lb of fat  determine lean body weight (LBW): total weight – fat weight: 168lbs – 47lbs = 121 lbs of lean mass)  calculate goal weight: divide current LBW by 76% which is 100% - goal BF%. 121 / 0.76 = 159lb

Waist to hip Ratio  excess body fat and its locations poses significant health risks. Clients with apple shaped bodies (carry weight around abdomen). If they have a high WHR they have a greater health risk.  WHR = waist measurement is divided by the hip measurement.  Your client has Hip circumference of 30 and waist of 42

MHR  age predicted HR: 220- age  Find for client: 37 years old, RHR: 79 bpm, 65% intensity  Karvonen formula: [(220- age) – (RHR)] x % Intensity + RHR  Exercise heart rate using Tanaka, Monahan and seals: [(208 – (0.7 x Age) x 85%}
