Clinical Trial Summary

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.

Outcome

Type Measure Description Time frame Safety issue
Primary Muscle power Muscle power of lower limbs measured by countermovement jump on force platform 30 minutes
Primary Patellar thickness Tendon thickness of the patellar tendon measured by ultrasound 60 minutes
Primary Monopodal Postural Sway Monopodal postural balance with open eyes in force platform 10 minutes
Secondary Muscular fatigue Muscle fatigue measured in each resting period by means of a countermoving jump to assess the loss of power. 30 minutes
