Polar Fitness Test

Select Test > Fitness

The Polar Fitness Test™ is an easy, safe, and quick way to measure your aerobic (cardiovascular) fitness at rest. The result, Polar OwnIndex, is comparable to maximal oxygen uptake (VO2max), which is commonly used to evaluate aerobic fitness. Your long-term level of physical activity, heart rate, heart rate variability at rest, gender, age, height, and body weight all influence OwnIndex. The Polar Fitness Test is developed for use by healthy adults.

Aerobic fitness relates to how well your cardiovascular system works to transport oxygen to your body. The better your aerobic fitness, the stronger and more efficient your heart is. Good aerobic fitness has many health benefits. For example, it helps in decreasing high blood pressure and your risk of cardiovascular diseases and stroke. If you want to improve your aerobic fitness it takes, on average, six weeks of regular training to see a noticeable change in your OwnIndex. Less fit individuals see progress even more rapidly. The better your aerobic fitness, the smaller the improvements in your OwnIndex.

Aerobic fitness is best improved by exercise types that use large muscle groups. Such activities include running, cycling, walking, rowing, swimming, skating, and cross-country skiing.

To monitor your progress, start by measuring your OwnIndex a couple of times during the first two weeks in order to get a baseline value, and then repeat the test approximately once a month.

With the Polar Fitness Test, you can also calculate the predicted maximum heart rate value (HRmax-p). The HRmax-p score predicts your individual maximum heart rate more accurately than the age-based formula (220 - age). For further information on HRmax, see User Settings.

To make sure the test results are reliable, the following basic requirements apply:

  • You can perform the test anywhere - at home, at the office, at a health club - provided the testing environment is peaceful. There should be no disturbing noises (e.g. television, radio, or telephone) and no other people talking to you.

  • Always take the test in the same environment and at the same hour.

  • Avoid eating a heavy meal or smoking 2-3 hours prior to testing.

  • Avoid heavy physical exertion, alcohol, and pharmacological stimulants on the test day and the previous day.

  • You should be relaxed and calm. Lie down and relax for 1-3 minutes before starting the test.

Before the Test

Wear the Transmitter

For further information, see Wear the Transmitter.

Enter User Information

Select Settings > User

To carry out the Polar Fitness Test, enter your personal user information (if you entered the personal user information before, there is no need to do this again) and long-term physical activity level in the User settings.

Set HRmax-p On

If you want to obtain your predicted maximum heart rate value, turn HRmax-p on.

Select Test > Fitness > HR max -p > On

Performing the Test

Select Test > Fitness > Start > Fitness Test Lie Down

The fitness test begins in five seconds. Arrows indicate that the test is ongoing. Stay relaxed and limit body movements and communication with other people.

If you have not set your long-term physical activity level in User Settings, Set your personal activity level is displayed. Select Top, High, Moderate, or Low. For further information on activity levels, see User Settings.

If your cycling computer does not receive your heart rate at the beginning or during the test, the test fails and Test failed, check WearLink is displayed. Check that the transmitter electrodes are wet and that the textile strap is snug enough, and start the test again.

When the test is over, you will hear two beeps. OwnIndex is displayed with a numerical value and level evaluation. For further information on evaluations, see Fitness Level Classes.

To display your Predicted maximum heart rate value press DOWN. Press OK to exit.

Update to VO2 max? is displayed.

  • Select Yes to save the OwnIndex value to your user settings and Fitness Test Trend menu.

  • Select No only if you know your laboratory-measured VO2max value, and if it differs more than one fitness level class from the OwnIndex result. Your OwnIndex value is saved only to the Fitness Test Trend menu only. For further information, see Fitness Test Trend.

Update to HR max? (if HRmax-p(if HRmax-p is on) is displayed.

  • Select Yes to save the value to your user settings.

  • Select No if you know your laboratory-measured HRmax.

Stop the test at any time by pressing STOP. Fitness Test canceled is displayed for a few seconds.

Saved OwnIndex and HRmax-p values, they will be used for calculating calorie consumption.

After the Test

Fitness Level Classes

Your OwnIndex is most meaningful when comparing your individual values and changes in them over time. OwnIndex can also be interpreted based on gender and age. Locate your OwnIndex on the table below, and find out how your aerobic fitness compares to others of the same gender and age.

Top athletes typically score OwnIndex values above 70 (men) and 60 (women). Olympic-level endurance athletes can reach values as high as 95. OwnIndex is highest in sports that involve large muscle groups, such as running and cross-country skiing.
