RESUMO:

The throwing motion, as well as other movements above the head performed in sports such as handball, imposes an excessive stress on the glenohumeral (GH) joint, since a very high angular velocity is generated during these movements, leading the joint to high tensile forces. The repeated performance of such movements generates some bone, capsule, and muscle adaptations in the joint that culminating in the development of posterior shoulder tightness and the Glenoumeral Internal Rotation Deficit, known as GIRD. As a consequence of these deficits, there is an association with a decreased range of motion (ROM), increased humeral retroversion, imbalance of muscle strength between medial and lateral glenohumeral rotators and impaired shoulder proprioception, which increases the risk of osteomyoarticular lesions of the shoulder. The objective of this study is to analyze the influence of GIRD on the biomechanical adaptations and on the neuromuscular performance in the shoulder complex of throwing athletes. It is an observational study, cross-sectional, which is currently in execution, and has a sample of 31 individuals who participated in the study (26,6±6 years, BMI 26,4±3,8). Were evaluated: ROM for medial (MR) and lateral (LR) rotations and horizontal shoulder adduction; sense of joint position of the shoulder during MR and LR motions, using a digital inclinometer Accumar®; and isometric force of MR and LR, using a manual dynamometer Lafayette®. From the evaluation of the ROM for MR, individuals with difference between shoulders less than 10º were allocated to the group without GIRD (18 individuals) and those with a greater difference than 10º were allocated to the group with GIRD (13 individuals). The statistical analysis used was ANOVA one-way for difference of ROM of MR, considering only groups as factor, and ANOVA two-way for the variables ROM of horizontal adduction, sense of joint position of MR and LR and force ratio LR/MR, considering groups and limbs as factors. It was considered p<0,05. Our partial results showed that the dominant shoulder (DS) presented lower ROM for horizontal adduction (p=0,01), however, with no difference between groups (p=0,37). For sense of joint position and force ratio variables, there was no difference between the shoulders nor between the groups (p>0,05). We concluded that the GIRD did not influence the variables, however presented lower ROM of horizontal adduction on the DS, suggesting a shoulder posterior tightness.
