PURPOSE: Jumping is used both in competitive and recreational sports for people of all ages. By determining and quantifying the change in impact force with different landing techniques after a jump, coaches and students perfect the different types of sports where jumping is used. The hypothesis is that landing with stiffer legs vs. bent legs will create greater force when landing. The rationale behind this is that when using bent legs, more muscles are being used, allowing less of a force impact due to these natural force springs in our body. METHODS: Using two subjects of different weights, we recorded them jumping twice onto a force plate. They each did one jump where they landed with stiff legs and another with bent legs. After each landing for each subject, we used a forceplate interfaced with the LabView software and analog to digital (A/D) board to capture ground reaction forces in the x, y, and z planes. With a forceplate system, the up and down axis is the z axis, the back to front axis is the y axis, and the side-to-side axis is the x axis The jumper jumps the same height for each jump and land with different techniques (stiff
