Brief Summary

Jiu Jitsu is a martial art that consists of various techniques that aim to place the opponent in submission. It is essentially a ground fight that requires large movement variety, among which flexibility is a substantial physical aptitude, required to perform specific positions of attack or defence, especially flexibility of the thoracolumbar spine and hamstrings. The literature reports that abnormal posterior lower limb neurodynamics may influence hamstring extensibility and muscle length, and lead to changes in perception of stretch and pain. The objective of the present study is to evaluate the effect of NM, using sliding techniques of the sciatic nerve, immediately after Jiu Jitsu training, on HM flexibility of Jiu Jitsu practitioners. The hypothesis is that NM sliders applied immediately after training would be as effective as an isolated intervention, as demonstrated in soccer players.

Study Groups

Neural mobilization

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.

Group Type: EXPERIMENTAL

Neural mobilization

Intervention Type: OTHER

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).
