耐力速度复合训练对新兵膝屈伸肌功能影响的等速测试研究

THE EFFECT OF COMBINED ENDURANCE AND SPEED TRAINING ON CHANGES IN MUSCULAR FUNCTION OF KNEE FLEXORS AND EXTENSORS IN RECRUIT SOLDIERS

为探讨耐力速度复合训练对新兵膝屈伸肌功能的影响 ,对 2 0名新兵进行为期 4周的耐力速度复合训练 ,训练前后采用Cybex 6 0 0 0型等速运动测试仪对新兵的膝屈伸肌肌力、肌爆发力及肌耐力进行等速测试并加以比较。结果发现 ,新兵训练后左膝屈肌的PT、TAE和ER值在快速测试中有明显的提高 (P <0 0 5 ) ;左膝伸肌的PT和ER值在快速测试中有明显的提高 (P <0 0 5 ) ;右膝屈伸肌除屈肌的PT、TAE值在快速测试中有明显的提高外余检测指标无改变。提示为期 4周的耐力速度复合训练可使部分膝屈伸肌产生适应 ,但不能达到全面发展新兵膝屈伸肌肌力。

To evaluate the influence of combined endurance and speed training on the knee flexors and extensors strength of army male recruits. At the beginning and end of their 4 week combined endurance and speed training, twenty recruits received isokinetic dynamometer test of flexors and extensors of both knees with the Cybex 6000 isokinetic dynamometer. The results showed: that there was a significant increase in the peak torque values, torque acceleration energy and endurance ratio of left knee flexors at high angular velocities (180°/s) after training. Meanwhile, the peak torque and endurance ratio were increased in left knee extensors at high angular velocities (180°/s),and the peak torque and torque acceleration energy were increased in right flexors at high angular velocities(180°/s). These data suggest that four weeks of combined endurance and speed training for recruits is not sufficient fo increase muscular strength, explosive force or muscular endurance of knee flexors and extensors.
