We found that female athletes exhibited reduced LED-test performance (p=0.001) and higher limb stiffness during landing (p=0.008) calculated on average within 51 ms of foot contact.

WebDec 22, 2024 · The formula for Hooke’s law specifically relates the change in extension of the spring, x , to the restoring force, F , generated in it: F = −kx F = −kx. The extra term, k , is the spring constant. The value of this constant depends on the qualities of the specific spring, and this can be directly derived from the properties of the spring ...
