Summary

The objective of this experimental study was to compare the electromyographic responses of sedentary youth with and without the administration of static stretching and neural mobilization. The sample was composed of sedentary students, divided, randomly, into neural mobilization practitioners (NMG; n=15; age=22±3 years), static stretching practitioners (SSG; n=15; age=23±4 years) and a control group (CG; n=15; age: 24±4 years). For this evaluation, an electromyograph (EMG; a four channel system) was used to monitor electrical activity in the femoral bicep muscles). In neural mobilization, hip flexion was conducted passively with the knee extended, and 30 plantar-to-dorsal flexion oscillations were completed per minute. For the static stretching, hip flexion with was completed passively with the knee extended and held for 6 seconds. The perception of effort was evaluated using the Perceived Force in Flexibility Scale. The statistical significance level was p\<0.05. Descriptive statistics such as the average, standard deviation, median, standard error and absolute change within groups (post-test - pretest) were calculated. The sample normality was evaluated using the Shapiro-Wilk test. For the response variable analysis, the paired Student's t-test (paired) or Wilcoxon test (nonparametric) was used for intragroup analysis. For the intergroup analysis, the multivariate analysis of variance (ANOVA) test was used, followed by the Tukey Post-Hoc test. A p\<0.05 significance level was adopted for the statistical evaluations. Microsoft Excel and the Statistical Package for Social Science (SPSS) version 14.0 were used for evaluation of the results.

Conditions

  • Electromechanical Dissociation

Interventions

OTHER

neural mobilization

In the neural mobilization group, the subject was positioned in dorsal decubitus, and the researcher performed hip flexion with the knee extended passively and performed 30 oscillations of plantar-to-dorsal flexion for one minute

OTHER

Static Stretching

In the static stretching group, the subject was positioned in dorsal decubitus, and the researcher performed hip flexion with the knee extended passively and held for 30 seconds; this type of stretching corresponds to the maintenance of increased amplitude posture, without surpassing the maximum movement limit, three times with an interval of 10 seconds between the repetitions.
