I have heard that the Defence Forces uses the Body Mass Index (BMI) as one
means of determining medical eligibility. Can you explain this?
The BMI is calculated by the formula: weight (kilograms) divided by height (metres) squared, i.e. kg/m2, and is a guideline of an appropriate range of body weight with respect to minimising certain health risks.
Under 17: you will be assessed by the examining medical officer in order to determine whether you could cope with the demands of training.
17 to 29: You fall within the acceptable range for entry.
30 and above: Is not acceptable for entry into the Defence Forces and youwill be classified as medically unfit.
*Please note that the BMI result is indicative only, other factors affect the result. An initial failure of the BMI in the case, for example, of well muscled but short rugby player will result in a Body Fat Composition Test being used in lieu of the BMI test.
