The study aimed at establishing the differences between the kinematic and dynamic parameters of reactive force which is one of the most important biomotor ability of sprinters. Reactive force was assessed during a drop jump from 45 cm. The basic kinematic and dynamic parameters were registered using the Smart 600E bipedal force platform which had been synchronised with a 3D infra-red ... https://mabelandfoxs.shop/product-category/apron/
