This test is suitable for active individuals but not for those The landing was executed on a special exercise mat. The standing broad jump is a perfect way to measure the explosive leg strength of an athlete. The world record for the standing long jump is currently held by Arne Tvervaag (Norwegian), who, in 1968, jumped 3.71 meters. Return your heels to the ground. Hold for a moment before using your glutes to push you back up to the starting position. The study aimed to investigate the acute effects of handheld loading on standing broad jump (SBJ) performance and biomechanics. (b) Straddle standing long jumpfrom the erect position, the feet are positioned in self-selected straddle position (about 3040 cm apart and with the left foot in front), then the subject dynamically lowers the body COM by flexing the knees to about 8590 (countermovement). Brockett C, Morgan D, Proske U. exercise 0000003081 00000 n (21), the most important elements that promote standing long jump performance are the ability to coordinate the arm movement and selection of the appropriate take-off angle. Test reliability refers to how a test is consistent and stable in measuring what it is intended to measure. In this article, I am going to look at the five phases of thevertical jump and show you how physics work during each of them. In the phase of initiation of take-off, the vertical ground reaction (% BW) force in the parallel foot placement jump amounts from 118.12 to 126.65 N on right and left legs, respectively. This applies to the right leg in the jump from the straddle position. Children's norms based on data from Texas Test 1973.
