摘要
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 discuss the characteristics of flexor and extensor torque of the knee joint by carrying out isokinetic testing on women handball players in Guangdong Province,and to provide some isokinetic test data for the strength and physical training research on handball players.Methods Flexor and extensor of knee joint in fourteen players from Guangdong provincial handball team were measured by CON-TREX isokinetic testing system.Relative peak torque,hamstring/quadriceps ratio,total work,average power and fatigue index were selected to study the isokinetic characteristics of the women handball players＇ knee joint.Independent t-tests were employed to compare the results between flexor and extensor.Results For women handball players,at the velocity of 60°/s（low speed test）and 240°/s（high speed test）,the relative extensor peak torque value was significantly greater than that of the flexor（P0.01）;at the velocity of 240°/s,the hamstring/quadriceps ratio was about 76%;at the velocity of 60°/s,the total work and average power of the extensor was greater than that of the flexor（P0.01）;at the velocity of 240°/s,the total work and average power of the extensor in left knee joint were greater than that of the flexor（P0.05）;the range of fatigue index was from 0 to 0.49.Conclusions The maximum strength and speediness strength of extensor was greater than that of the flexor;at the velocity of 240°/s,the hamstring/quadriceps ratio of the knee joint was relatively lower,which showed that the speediness strength of flexor in knee joint was relatively low;the speediness strength and the working capability of the extensor in knee joint was greater than that of the flexor;the fatigue index of extensor and flexor of knee joint was relatively low,which may indicate that the level of strength stamina of extensor and flexor in knee joint was relatively low.
