Comparison between q angle measurements and their relationship with knee health in women practicing and not practicing futsal

Abstract

Introduction: Futsal is a sport that requires technical gestures that overload the knee, increasing the risk of injury in these regions. Apparently, the quadriceps angle may have some influence on the health of the knee. Therefore, further investigations are important to quantify and qualify the postural profile of athletes in this modality. Objectives: To verify how the strengthening of the muscles that involve the hip joint, as well as the stabilizing muscles of the knee joint, can interfere in the treatment of patellar instability. Methods: The knees of 16 young women were evaluated (NPG = 8 physically inactive; and GFP = 8 futsal players). To verify the disorders related to the knees, a Lysholm Knee Score Scale questionnaire was applied, then, using reflective markers, photogrammetry was used to analyze the deviations of the lower limbs. The comparison between the measures of postural deviations of the lower limbs and the scores obtained by a questionnaire was analyzed using the test of comparison of independent means. Pearson's correlation was performed to verify the relationship of data between the two groups. Results: In the trained group, no significant correlations were observed between the quadriceps angles and the scores obtained through the questionnaire. On the other hand, in the sedentary group, there was a high negative and significant correlation between the angle of the left quadriceps and the scores found in the application of the questionnaire. Conclusion: There are no differences in the indicators of knee discomfort between athletes and non-futsal athletes. However, the results suggest that there may be a protective effect on knee health in response to the practice of futsal by women.
