Primary Outcome Measures

Name	Time	Method
To evaluate the ability to generate torque (force), determined by tests on the isokinetic dynamometer performed at the beginning and end of the study.

Secondary Outcome Measures

Name	Time	Method
To analyze muscle thickness of the vastus medialis, vastus lateralis, vastus intermedius, rectus femoris, biceps femoris, semimembranosus and semitendinosus, determined by an ultrasound, in which measurements will be performed at the beginning and end of the study.;To analyze the velocity, step length and width in the gait tests at preferred and maximum speed, which will be performed at the beginning and at the end of the study.;To evaluate the number of repetitions in the functional sit-and-stand test, which will be performed at the beginning and end of the study.;To analyze strength ratio between knee flexors and extensors, which will be measured by an isokinetic dynamometer test, at the beginning and at the end of the study.;To collect and analyze myoelectric activity of the vastus medialis, rectus femoris, vastus lateralis, biceps femoris and semitendinosus muscles, during a co-contraction session, which will be measured by a wireless electromyograph, at the beginning and end of the study.
