Product Information

Every athlete and sportsperson wants to know that they are getting stronger, faster and more powerful. I’ve also been given direct access to the manufacturers of the Skyhook Mat who have sent me several videos of it being used, so I could get a feel for how the device functions. Continually Updating With New Products & Information Jump Range A general range of vertical jumps for high school athletes is about 26 to 28 inches. Elite high school football players, however, will have a vertical exceeding 30 inches, with college recruits reaching 36 or more inches. This wide range of good verticals depends on position and overall athletic ability. How accurate is the vertical jump pad? This makes the device super easy to use with a wide range of athletes of varying heights and abilities.

If you’re using tape, wrap some tape around itself til you have a ball or donut shaped piece of tape attached to the tip of your middle finger.

history: This method described above for measuring a person's vertical jump height is sometimes known as a Sargent Jump, named after Dudley Sargent, who was one of the pioneers in American physical education. Reattempt the jump 3-4 more times until you feel as though you’ve given it your best effort. 3. Calculate Your Vertical Jump

Vertical jump height can also be measured using a timing mat. The vertical jump test is usually performed with a counter movement, where there is bending of the knees prior to the jump. The test can also be performed as a squat jump, starting from the position of knees being bent. Finally, jump testing is not the same as jump training or jump games. Athletes love dunking in the gym for fun, if they have the springs, but they are not fans of squat jumps with their hands on their hips for scientific purposes. The limiting factor in jump testing is not the technology, it’s whether the athlete wants to jump or not. For the most part, athletes don’t have a high maximal drive to produce an all-out effort when the reward is usually low. If athletes are not engaged, the numbers are meaningless. Coaches must create a testing environment that is engaging, and only test if the answers they get are going to change what they do in a purposeful way. Procedures Coaches Use That Help or Hinder ResultsWall Mounted— The original and most simple method for measuring vertical jump height is against a wall. Although you can use just any wall and a piece of chalk in the hand, there are also other wall mounted grid options. [ more] Derive the formula vi = -g*T/2 from the formula sf = si + vi*T + (g*T²)/2. The initial and final positions are the same before and after the jump, so set them to zero and factor: T(vi + g*T/2) = 0. Setting the factors equal to zero gives you two results: T = 0 and vi + g*T/2 = 0. What exercises make you jump higher? FOX, E.L. and MATHEWS, D.K.
