Jump test

There are three kinds of jump tests to choose from: squat, countermovement and continuous. The squat and countermovement tests measure your explosive strength, but in the countermovement jump test your muscles and tendons also do a pre-stretch that lets you use elastic energy, usually allowing you to jump higher. The continuous jump test measures your anaerobic power. It is especially useful for those who do sports that require anaerobic power, in other words maximal effort for short periods.

To do the Jump test, go to Tests > Jump Test. To perform the test you need a Polar Stride Sensor Bluetooth® Smart. For more information, see Polar Stride Sensor Bluetooth® Smart

If you haven't paired a Polar Stride Sensor Bluetooth® Smart with V800, You need a Polar stride sensor is displayed when trying to enter Jump Test.

Before performing any of the jump tests, make sure you have warmed up properly, especially your leg muscles. When performing any of the tests, always use the same correct jumping technique to maximize the comparability and reliability of the results.

Your latest test result is shown in Tests > Jump test > Latest result. Only your most recently performed test result is shown. You can view your previous results in the V800 diary. For a visual analysis of your Jump test results, go to the Flow web service and select the test from your Diary to view details from it.

 

Squat Jump

The squat jump test measures explosive strength. This test is performed by starting with your knees bent in a 90 degree angle, and jumping vertically as high as possible from that position. Hands should be held on the hips to avoid the effect of arm swinging to the test. Knees and ankles should be extended at take-off, and they should be in a similar extended position when landing on the ball of the foot.

In the test you perform three attempts of the squat jump and the best attempt is the test result. Give yourself a short recovery period between attempts to ensure maximal effort on every attempt.

Performing the Squat Jump

Wear the Polar Bluetooth® Smart Stride Sensor, and choose Jump test > Squat, and press START. Searching for stride sensor is displayed. Squat jumps Start now! is shown when you can start the test.

  1. Stand with your hands on your hips and knees bent in a 90 degree angle. Stay still for a few seconds.
  2. Jump vertically without any countermovement.
  3. Land with both feet with your legs straight and ankles extended.
  4. Perform three attempts of the squat jump. Give yourself a short recovery period between attempts to ensure maximal effort on every attempt.

It is important not to perform any kind of countermovement during the squat jump test.

During the test you will see the number jumps performed (1/3, 2/3 or 3/3), and the height of your last jump e.g. 53 cm.

 

Test Results

After the test you will see the heights of all three of your jumps

 

 

Countermovement Jump

The countermovement jump test measures explosive strength. This test is performed by starting in an upright standing position and squatting down to a 90 degree leg bend position before immediately jumping vertically as high as possible. Hands should be held on the hips to avoid the effect of arm swinging to the test. Knees and ankles should be extended at take-off, and they should be in a similar extended position when landing on the ball of the foot.

In the test you perform three attempts of the countermovement jump and the best attempt is the test result. Give yourself a short recovery period between attempts to ensure maximal effort on every attempt.

Performing the Countermovement Jump

Wear the Polar Bluetooth® Smart Stride Sensor, and choose Jump test > Countermovement, and press START. Searching for stride sensor is displayed. Countermovement Start now! is shown when you can start the test.

  1. Stand upright with your hands on your hips.
  2. Squat rapidly to about a 90 degree knee angle, and immediately jump vertically.
  3. Land with both feet with your legs straight and ankles extended.
  4. Perform three attempts of the countermovement jump. Give yourself a short recovery period between attempts to ensure maximal effort on every attempt.

During the test you will see the number jumps performed (1/3, 2/3 or 3/3), and the height of your last jump e.g. 59 cm.

Test Results

After the test you will see the heights of all three of your jumps.

 

 

Continuous Jump

The continuous jump test measures your anaerobic power. This test is especially useful for those who do sports that require anaerobic power, in other words maximal effort for short periods.The aim of the continuous jump test is to perform the highest number of jumps with maximum height in the set time period.

The continuous jump test is performed by squatting down until the knees are bent in a 90 degree angle, and then rapidly jumping vertically as high as possible, and landing with both feet at the same time, bending the knees, and repeating the vertical jumping movement until the set time period is over. The test should be started with maximal effort, jumping as high as possible as rapidly as possible. As the test proceeds you will naturally become fatigued but keep maximal effort throughout the test. In the Flow web service you can analyze your test jump by jump, and see how your jump height decreased during the test.

Performing the Continuous Jump

Before performing the continuous jump test, set the duration of test. Choose Jump test > Set duration of cont. test The duration can be set to 15 seconds, 30 seconds, 60 seconds or Set other duration. If you choose Set other duration, you can set the duration anywhere from 5 seconds to 300 seconds.

Wear the Polar Bluetooth® Smart Stride Sensor, and choose Jump test > Continuous, and press START. Searching for stride sensor is displayed. Continuous jumps Start now! is shown when you can start the test.

  1. Stand upright with your hands on your hips.
  2. Squat until your knees are in a 90 degree leg bend position, and immediately jump vertically.
  3. Land with both feet with your legs straight and ankles extended.
  4. Repeat the jump movement continuously until the test is over (you will be notified with audio and vibration when the test is over).

During the test you will see the number of jumps performed, and the time remaining .

 

Test Results

After the test you will see the number of jumps performed, the average height of your jumps and the average power per kilogram/pound.
