– Keep hand placement consistent – i.e. hands on hips, behind the back, free – Jump Horizontally as far as possible – Hold landing position for 2 seconds
– Based on distance jumped – Determine limb symmetry – Quality is important Karyn Haitz, Rebecca Shultz, Melissa Hodgins, Gordon O. Matherson, J Ortho Sports Phys Ther 2014.
