 The unilateral vertical jump will be used to measure performance, as this movement requires triceps surae strength 9. The vertical jump will be evaluated using a pressure plate BIOMEC 400 v1.1 EMG Systems do Brasil connected to computer Inter Core 2 Dual with 2 GHz and 250 Giga bytes. This system quantifies the distribution of vertical ground reaction force in a static or dynamic position with a sampling frequency of 40 Hz using four force sensors two anterior and two posterior capable of supporting 150 Kg. Each sensor stores analog data, which are amplified and converted to digital data interpreted using the Biomec 400 software program EMG Systems do Brasil. This system records the distribution of force among the four points and changes in body sway in the anteroposterior Y axis and mediolateral X axis directions. The force plate will be positioned on an even surface. Levelness will be determined by two levels attached to the extremities of the force plate. The volunteer will be instructed to stand on the dominant leg with hands on the hips and jump as high as possible, landing on the same leg. Initially, three jumps will be performed to familiarize the volunteer with the procedure, with a one-minute rest interval between jumps. After a two-minute rest interval, three additional jumps will be performed with a one-minute rest interval between jumps, which will be considered for evaluation. Jump time will be determined using the following formula:
