Brief 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 Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Muscle power [ Time Frame: 30 minutes ]
    Muscle power of lower limbs measured by countermovement jump on force platform

  2. Patellar thickness [ Time Frame: 60 minutes ]
    Tendon thickness of the patellar tendon measured by ultrasound

  3. Monopodal Postural Sway [ Time Frame: 10 minutes ]
    Monopodal postural balance with open eyes in force platform


Secondary Outcome Measures :
  1. Muscular fatigue [ Time Frame: 30 minutes ]
    Muscle fatigue measured in each resting period by means of a countermoving jump to assess the loss of power.
