OPERATION

BMI (Body Mass Index) Measurement

BMI is a useful tool that shows the relationship between weight and height that is associated with body fat and health risk. The table below gives a general rating and BMI score:

 

BMI

Underweight

Below 18.5

Normal

18.5 – 24.9

Overweight

25.0 – 29.9

Obesity

30.0 and above

There are limitations however. It may overestimate body fat in athletes and others who have a muscular build. It may also underestimate body fat in older persons and others who have lost muscle mass.

When choosing the BMI program you will be prompted to enter your height and weight and the computer will calculate and display your Body Mass Index. The console will display “IDEAL BMI RANGE”. The ideal or normal range is 18.5 – 24.9. The console will also display your ideal weight range for your height.

CONSULT YOUR PHYSICIAN FOR MORE INFORMATION ABOUT BMI AND THE WEIGHT THAT IS APPROPRIATE FOR YOU.

Recovery Test

Recovery Test shows how quickly your heart recovers from an exercise state to a more restful state. Improved recovery is an indicator of increasing fitness.

For the console to perform the Recovery Test two things must happen. You must press the RECOVERY button, AND, the console must be displaying your heart rate. When both of these situations occur, then the console will perform the Recovery Test.

The console will show “01:00 STOP” and the time will begin to count down. Stop exercising but continue to grip the heart rate sensors. After 5 seconds, the display will show “00:55 RELAX” and will continue to count down to 00:00. For the entire minute the console will also show your heart rate. You must grip the heart rate sensors for the duration of the test.

The display will continue to show “RELAX” and your heart rate until the clock counts down to 00:00. The console will then calculate your recovery score.

Recovery Score = Your heart rate at 1:00 (the beginning of the test) minus your heart rate at 00:00 (the end of the test)
