Bosco Squat Jump

The Bosco Squat Jump is a test used to measure leg power and is a variation of the vertical jump test. Unlike traditional vertical jump tests, the Bosco Squat Jump does not allow for arm swinging or countermovement. By eliminating arm movements, this test isolates the leg muscles and reduces variations in coordination. The Bosco Squat Jump is part of the Bosco Ergo Jump System, which utilizes technology such as the Bosco Ergojump System or similar devices like jump mats, Myotest, or infrared laser systems.

Test Procedure

Before conducting the test, it is important to explain the procedure to the subject and screen for any potential health risks. Obtain informed consent and record basic information such as age, height, body weight, and gender. Additionally, check and calibrate the timing mat measurement and ensure the subject performs an appropriate warm-up.

During the test, the athlete stands on a mat, distributing their weight evenly over both feet. The hands are placed on the hips throughout the test. The athlete then squats down until their knees are bent at a 90-degree angle while maintaining a straight trunk. Once the mat is reset, the athlete jumps vertically as high as possible and lands back on the mat with both feet touching the ground simultaneously. The best score of at least three attempts is recorded, allowing for sufficient rest between trials. It is important to note that both the take-off and landing must be from both feet, with no initial steps or shuffling. Participants may continue to jump as long as improvements are being made.

The timing mat used in the Bosco Squat Jump test provides a score of the time in the air, which can then be used to calculate the vertical jump height. The formula for calculating jump height is as follows: jump height = 4.9 x (0.5 x Time)^2.

Advantages and Disadvantages

One disadvantage of the Bosco Squat Jump test is that the jump height can be affected by the amount of knee bending. If the subject does not bend their knees to the required 90 degrees each time, the test may be invalidated. Additionally, this test requires a touch-sensitive timing mat and is more complex than simply jumping up against a wall.

Tips and Considerations

Subject performance may improve with practice, and verbal encouragement should be provided to encourage maximal effort each time. The Bosco Squat Jump test is just one component of the Bosco Ergo Jump System, which provides a comprehensive approach to measuring athletic performance.
