The body mass index (BMI) calculator is a bonus feature of the PowerCalc Cyclists Power Calculator
|
The body mass index calculator can be opened by selecting Body Mass Index from the Tools menu. The body mass index (BMI) is a method of classifying body weight as defined in The Complete Guide to Sports Nutrition, Anita Bean, A & C Black (Publishers) Ltd., ISBN 0 7136 3605 X.
Just change the values for height and weight and the program does the rest ;-) |
The BMI classification is calculated by deviding the athletes weight in kilogrammes by the square of his height in metres(i.e. height times height)
The body mass classifications are defined as follows:
| Less than 20 | Underweight |
| 20 - 24.9 | 'Normal' weight (Grade 0) |
| 25 - 29.9 | Overweight/'plump' (Grade I) |
| 30 - 40 | Moderately obese (Grade II) |
| More than 40 | Severely obese (Grade III) |
It should be noted that this method gives a rough guideline only. BMI tells you nothing about body composition or fat content. Remember that muscle is denser than fat, so some very lean muscular people (weight trainers etc.) would be classed as overweight, by this method. If in doubt - look in the mirror! Or try using the body fat percentage calculator instead.

For those of you who can't run Windows I have done a FREE Javascript version of the body mass index calculator that you can run in your web browser.
