The objective of this study is to know the acute effects of a squat protocol in: 1- lower limb muscle power analyzed by countermovement jump on force platform and upper limb through a bench press with encoder test; 2 - the unipodal postural equilibrium by force platform; 3 - the patellar tendinous thickness measured by ultrasound.
