Associação do torque de abdutores do quadril e alinhamento estático do pé com a amplitude de movimento passiva de rotação interna do quadril em atletas de tênis

Abstract

Introduction: Tennis is a sport practiced throughout the world. Most of the force used to strike the ball is derived from the energy produced by the lower limbs. As a result, the hip joint suffers mainly lateralizantes and rotational forces during the coup understanding the interaction of variable anatomical alignment of the feet and torque of the hip abductors in the production of passive hip internal rotation in tennis athletes allows design effective strategies to control the burden on that joint and prevent injuries. Objective: To analyze the association between hip abductor torque of static foot alignment and with the passive ROM of hip internal rotators of tennis athletes. Materials and methods: We conducted an observational cross-sectional analytical, with 46 tennis players of different categories of partnership LAPREV and MTC. We collected the SFA, WMD, FABQ and analyzed the association between variables and differences between dominant and non dominant members. Results: We found an association (p <0.05) between FABQ and WMD. There was no association between ATA and WMD. Differences between dominant and non dominant was found only for the FABQ (p <0.05). Conclusion: There is an association between the isometric strength of hip abductor muscles and passive range of motion of internal rotation. The dominant side showed a greater isometric strength of hip abductor muscles when compared to non-dominant side.
