Intervention: This is a test that was developed by the Laboratory of Sports Physiotherapy of FCT/UNESP - Presidente Prudente. The test will be performed on the Biodex System Pro 4 isokinetic dynamometer (Biodex Medical System, Shirley-NY, USA). At first, participants will be be positioned and fixed on the device itself by their trunk, hips, thighs and by the distal region of the assessed lower limb (dominant). The protocol is composed by a 10 knee flexo-extension warm up at the speed of 330º/s, respecting the amplitude of 90º, then a 30 second isometric contraction from 50% to 60% of the maximum participant effort, according to the Effort Perception Scale. The test starts after two minutes of rest. So that it can take place, participants will be instructed to make as much effort as possible, according to the same scale, for as long as possible, until they can't keep muscle contraction no longer. To stimulate participants, evaluators will offer verbal motivation and they will follow a monitor, coupled to the device, which offers the power generation line which works as a visual feedback during all test long.
