Auralpressure: Abalakov Jump Test for Measuring Leg Power

The Abalakov Jump is a vertical jump test utilized to assess leg power. It is named after the scientist who first described this method of testing leg power. This test is a part of the Bosco Jump Test Protocol and allows arm swinging for maximum height. In this article, we will explore the Abalakov Jump, its equipment requirements, testing procedures, scoring, and some important considerations.

Abalakov Jump

Equipment Required

To perform the Abalakov Jump, you will need the Bosco Ergojump System or a similar device such as a jump mat, Myotest, or an infrared laser system. Additionally, you will need recording sheets to document the results.

Pre-test Procedures

Before conducting the test, it is essential to explain the procedure to the participant and obtain their informed consent. Perform a screening to identify any potential health risks. Record basic information such as age, height, body weight, gender, and test conditions. Ensure that the timing mat is properly calibrated. Lastly, instruct the subject to warm up adequately.

Testing Procedure

  1. The athlete stands upright in socks or bare feet on the mat, with their weight evenly distributed over both feet.
  2. The athlete squats down until their knees are bent at a 90-degree angle, simultaneously swinging their arms back behind their body.
  3. Without pausing, the athlete swings their arms forward and jumps as high as possible, landing back on the mat with both feet simultaneously.
  4. The take-off must be from both feet, with no initial steps or shuffling. The subject must also avoid pausing at the base of the squat.
  5. Record the best result out of at least three attempts. Athletes may continue to jump as long as they are improving. Allow sufficient rest between trials.

The timing mat provides a score of the time in the air, which can be used to calculate the vertical jump height using the following formula: jump height = 4.9 x (0.5 x Time)^2.

Important Considerations

It is crucial to note that the jump height can be affected by the degree of knee bending. Therefore, to ensure the accuracy of the test, the subject must bend their knees the required 90 degrees consistently during each attempt.

Here are some additional points to keep in mind:

  • Participants may benefit from practice and should be encouraged to give their maximum effort each time.
  • The Abalakov Jump test was first described by Abalakov in 1938 as a means of measuring leg power.
  • There is an Abalakov Apparatus or Abalakov Belt available, which uses an attached cord to directly measure the displacement of the center of gravity when testing vertical jump height.


Q: Is the Abalakov Jump suitable for all individuals?
A: Yes, the Abalakov Jump can be performed by athletes of all levels to assess leg power.

Q: Can the Abalakov Jump be practiced to improve performance?
A: Yes, participants can benefit from practice and training to enhance their jumping ability.

Q: Are there any alternative tests similar to the Abalakov Jump?
A: Yes, other tests such as the Bosco Squat Jump, Force Plate Vertical Jump, and vertical jump using a timing mat are similar to the Abalakov Jump.


The Abalakov Jump is a valuable test for evaluating leg power. By following the proper testing procedures and considering the participant’s technique, accurate results can be obtained. Practice and training can lead to improvement in vertical jumping ability.
