The intervention is always performed after Jiu Jitsu practice and at the training site itself. Neural mobilization consisted of the execution of a sciatic nerve sliding technique in three sets of one minute for each lower limb with an interval of one minute between sets, twice a week, for five consecutive weeks, totaling 10 interventions (Garber et al., 2011). The order of the first lower limb to be submitted to the intervention is not standardized, being at the discretion of the subjects.

Neural mobilization (NM) is a physiotherapy method aimed at restoring the dynamic balance between the relative movement of neural tissues and surrounding mechanical interfaces, and different techniques are used for the treatment of various compression syndromes as well as other pain conditions, such as back and neck pain (Basson et al., 2017; Ellis and Hing, 2008). The main techniques used are neurodynamic sliders and neurodynamic tensioners, with the tensioning techniques being considered the more aggressive approach, in which the increase in nerve length occurs (Silva et al., 2014). The neurodynamic sliders techniques are gentle maneuvers as they involve nerve lengthening at one joint and simultaneous reduction in its length at an adjacent joint in order to produce sliding movements of neural structures relative to adjacent tissues (Efstathiou et al., 2015).

consisting of passive knee extension with hip and knee stabilized at 90º, with the contralateral limb stabilized at the middle third of the thigh and leg by another researcher, and upper limbs along the trunk. From this position passive extension of the knee was performed by the researcher until the patient communicated the sensation of discomfort without pain in the tested hamstrings. This test shows intra-examiner reliability of 0.99.

consisting of raising the limb through passive hip flexion, keeping the knee extended and the subject in the dorsal decubitus position on the mat with both legs extended and upper limbs along the trunk. The assessment of the hip angle was performed by flexing the hip and maintaining the extension of the knee and ankle free, with the contralateral limb stabilized in the middle third of the thigh and leg by another researcher. It is reported that the SLR has a dual function, besides measuring the flexibility of hamstrings it also accesses the sciatic nerve and can test its mobility (Rolls and George, 2004).
