Inclusion criteria: The study will be attended by men, university football players from the city of Natal / RN aged between 18 and 35 years old who regularly train and play football at least 3 times a week. The following will not be included: subjects with body mass index (BMI) less than 18.5 kg / m-2 and greater than 30 kg / m-2; with musculoskeletal injury in the lower limbs in a period of three months before the tests; with lower limb surgery within six months of testing; with uncontrolled metabolic diseases; with inflammatory rheumatological condition or severe cardiovascular and / or pulmonary disease that prevents them from carrying out the proposed evaluation and tests.
Exclusion criteria
Exclusion criteria: The exclusion criteria adopted were: missing a research data; at any time and for any reason expressing a desire to leave the study; present a health problem that prevents them from continuing to participate in the research; use drugs or any therapeutic resources to improve performance or practice unusual or strenuous physical activities during research period.

| Functional performance For the assessment of the functional performance that will be performed on the non-dominant limb, the tests will be used: the Side Hop Test and the shuttle run test. They will be evaluated on the second day, 45 min after the IPC and 24 hours later. The Side Hop Test is used to assess strength and confidence in the lower limbs, in which the individual will remain standing on the non-dominant limb. At your side, there will be two parallel lines with a distance of 30 cm between them and the volunteer will have to perform 10 jumps with the non-dominant limb in the shortest possible time, jumping across between one line and the other. The volunteers will be instructed to jump as quickly as possible and two attempts will be made, and the one with the shortest time will be recorded. Attempts will not be accepted in which the volunteer lands within the space of 30 cm between the lines and the attempts will be repeated until he completes two valid attempts. Familiarization will take place on the second day so that the individual can get to know the test. (ITOH et al, 1998) Shuttle run test, to assess athletes' agility. A manual stopwatch will be used to measure time. The assessment was performed on a flat surface, with feet properly shod. The path was marked by two cones 10 m apart, where the individuals made the turn (180º turn), in the cone without touching it, and returned to the exit point, completing 20 meters, in the shortest possible time. Two attempts wil be made, with a two-minute rest interval between each repetition, with the best result being recorded. (STEPHENS et al., 2006) | — |

| Rate of Force development The rate of force development (RFD) will be extracted from the highest peak torque incorporated in the MVIC. RFD derives from the analysis of the force curve recorded during an explosive voluntary contraction and can provide important physiological information such as the role of neural factors (analysis of the first 50ms) and muscle factors (analysis between 100ms and 200ms) in the strength production and neuromuscular fatigue (AAGAARD et al., 2002; MAFFIULETTI et al., 2016). To analyze a RFD the extracted curves from the MVIC filtrates with a low pass of 15 Hz (Butterworth, 4th order). In order to identify the peak torque in the curves, the beginning of the muscular action will be visually identified and soon afterwards the curve will be cut at a time defined from 1 second before to 1 second after the beginning of the contraction. The cutouts of the curves covered by the mathematical algorithm capable of identifying the beginning of the contraction (point in the timeline when the torque exceeded by 2.5% of the difference between the baseline value and the peak torque value). Peak torque will also be identified in the 0 to 30ms, 0 to 50ms, 0 to 100ms and 0 to 200ms intervals. (AAGAARD et al., 2002; SCHETTINO et al., 2014; CERQUEIRA and VIEIRA, 2019). The above analyzes will be performed with the MATLAB 7.6.0 R2008a software (MathWorks, Natick, MA). ;Perceived Exertion It will be evaluated using the modified 10-point Borg scale on the second, third and fourth day immediately after the performance of the neuromuscular performance. After completing the task, it will be explained to the volunteer that it is a scale of 0-10, where 0 means “no effort” and 10 means “maximum effort” that will prevent you from continuing to exercise. (LOENNEKE et al., 2015);Feeling scale during interventions It will be evaluated through the Feeling Scale which consists of 11 points, ranging from -5 (very bad) to +5 (very good) and will be used to assess whet | — |
