目的对广东省女子手球队运动员膝关节进行等速向心测试,探讨手球项目运动员膝关节屈伸肌群等速测试特征,为手球项目运动员的力量训练和相关的体育科研提供参考。方法运用CON-TREX等速测试系统对14名广东省女子手球运动员的膝关节进行等速向心测试,选取相对峰力矩、屈伸肌峰力矩比值、平均功率、总功和疲劳指数5个指标来研究手球项目运动员膝关节屈伸肌群的等速测试特征。选取独立样本t检验比较屈肌和伸肌的测试结果。结果膝关节伸肌相对峰力矩值在慢速测试(60°/s)和快速测试(240°/s)时均明显大于屈肌(P<0.01);女手队员膝关节屈伸肌峰力矩比值在快速测试(240°/s)时为76%左右;膝关节屈伸肌平均功率和总功在慢速测试(60°/s)时表现为伸肌大于屈肌(P<0.01),在快速测试(240°/s)时表现为左膝关节伸肌大于屈肌(P<0.05);女手队员膝关节屈伸肌疲劳指数范围在0～0.49之间。结论女手队员膝关节伸肌的最大力量和快速力量大于屈肌;女手队员膝关节屈伸肌峰力矩比值在快速测试(240°/s)时略微偏低,说明女手队员膝关节屈肌快速力量偏低;女手队员膝关节伸肌的快速力量和肌肉工作能力均大于屈肌;女手队员膝关节屈伸肌疲劳指数偏低,说明女手队员膝关节屈伸肌的力量耐力水平比较低。
OBJECTIVE To test the isokinetic test of knee joint of Guangdong women’s handball team athletes, and to explore the characteristics of isokinetic test of knee flexors and extensors group in handball program, and provide references for the strength training of handball team athletes and related sports science research. Methods CON-TREX isokinetic test system was used to measure the isokinetic heart rate of 14 female handball players in Guangdong Province. The relative peak torque, peak flexion / flexion torque ratio, average power, total work and fatigue index Study on isokinetic test of knee flexors and extensors of handball athletes. Select independent samples t-test flexor and extensor test results. Results The relative peak torque of knee extensors was significantly higher than that of flexors at 60 ° / s and 240 ° / s (P <0.01) 76% at the fast test (240 ° / s). The average power and total work of the flexors and extensors of the knees were higher than flexors (P <0.01) in the slow test (60 ° / s) At 240 ° / s, extensors of the left knee were greater than those of the flexors (P <0.05). The fatigue index of the flexors and extensors of the knee of the female hand was between 0 and 0.49. Conclusions The maximal strength and rapid strength of knee extensors in female hand members are greater than those in flexors. The ratio of peak flexion / flexion moment of female knee hand members is slightly lower at 240 ° / s in fast test, indicating that female hand knee flexors The rapid strength and low muscle strength of the female hand were higher than that of the flexor flexor. The fatigue index of knee flexor and extensor of the female hand was lower than that of the flexor and extensor muscle, indicating that the strength and endurance of the flexor and extensor muscle of the female hand were lower .
