(1) To determine the reference values of hip abductor torque in youth athletes; (2) To investigate the influence of sex, age and sports on hip abductors torque.
Cross-sectional.
Sports clubs.
301 volleyball, basketball and futsal athletes between 10 and 19 years of age.
Mean value of three maximal isometric hip abductor torques, evaluated using a hand-held dynamometer.
The mean values of maximal isometric hip abductor torque ranged from 1.03 to 1.50 Nm/kg. The dominant hip abductor torque values were greater in 15-19 years old (1.41 ± 0.27 Nm/kg) than in 10-14 years old (1.12 ± 0.31 Nm/kg). In addition, the hip abductor torque values were smaller in basketball players (1.15 ± 0.31 Nm/kg) than futsal (1.34 ± 0.37 Nm/kg) and volleyball players (1.28 ± 0.25 Nm/kg). The comparison of hip abductor torque between futsal and volleyball players revealed no difference. The hip abductor torque values were greater in male volleyball athletes (1.28 ± 0.25 Nm/kg) than female volleyball athletes (1.13 ± 0.22 Nm/kg).
This study established reference values for maximal isometric hip abductor torque in youth volleyball, basketball and futsal athletes. In addition, the results demonstrated that sex, age and sports influenced hip abductor torque.
（1）确定青年运动员髋外展肌力矩的参考值；（2）研究性别、年龄和运动对髋外展肌力矩的影响。
横断面研究。
运动俱乐部。
301 名年龄在 10 至 19 岁之间的排球、篮球和五人制足球运动员。
使用手持测力计评估的三次最大等速髋外展力矩的平均值。
最大等速髋外展力矩的平均值范围为 1.03 至 1.50 Nm/kg。15-19 岁年龄组（1.41 ± 0.27 Nm/kg）的优势髋外展肌力矩值大于 10-14 岁年龄组（1.12 ± 0.31 Nm/kg）。此外，篮球运动员（1.15 ± 0.31 Nm/kg）的髋外展肌力矩值小于五人制足球运动员（1.34 ± 0.37 Nm/kg）和排球运动员（1.28 ± 0.25 Nm/kg）。五人制足球和排球运动员的髋外展肌力矩比较无差异。排球男运动员（1.28 ± 0.25 Nm/kg）的髋外展肌力矩值大于排球女运动员（1.13 ± 0.22 Nm/kg）。
本研究为青年排球、篮球和五人制足球运动员的最大等速髋外展肌力矩建立了参考值。此外，结果表明性别、年龄和运动影响髋外展肌力矩。
