四头肌

METHODS: These patela were fixed and tested in the measure rack using electrometric technique under 50, 100, 150, 200, 250, and 300 N load. The anterior patella stress without fixation, and following stainless steel wire fixation or Ni-Ti Alloy wire fixation was measured.

股四头肌拉力以50，100，150，200，250，300 N加载和卸载两种方式作用于受试髌骨，应用电测法测量不完全横形髌骨骨折未经金属丝固定、钢丝环形加"8"字内固定及镍钛合金丝环形加"8"字内固定后的髌骨前面应力。

In this study isometric quadriceps strength and voluntary activation at different knee angles were investigated in a group of healthy adults.

The findings indicates that the cross-sectional areas of knee joints' flexors and extensors of athletes of football are bigger than that of skating, the main difference lies in the muscles of quadriceps femoris and the clusters of biceps femoris, semitendinosus and semimembranosus muscles.

结果表明：足球运动员大腿肌肉横断面积大于速滑运动员，差异主要表现在股四头肌和股后肌群。

The strengths of isometric and isotonic contractions of the quadri ceps and the hamstrings muscles of the affected and contralateral thighs were recorded.

所有患者在关节镜再视术前使用MyretRZ-450型CybexⅡ等速肌肉功能测试器，对患侧和健侧进行股四头肌和腘绳肌的等长(60°和90°)和等速(60°/s和180°/s)肌力测定。

If you tend to hyperextend, typical calf and hamstring stretches done with a straight knee can aggravate the problem unless you take care to engage your quadriceps.

如果你已经有超伸的情况，那伸直膝盖做小腿和腘绳肌的拉伸会加剧超伸的情况，除非你同时收紧你的股四头肌。

After three courses of treatment,investigate the symptom curative effect integral and the improvement rate ,and compare amplitude variation in EMG of the rectus femoris ,vastus medialis ,vastus lateralis in two groups.

治疗三个疗程后，观察两组膝关节骨性关节炎的症状疗效积分及改善率的变化，并比较治疗前后股四头肌的肌电图波幅(amplitude，AMP)的变化。

Some quadriceps muscle cell had vacuolar degeneration and lysis.

股四头肌部分肌细胞发生空泡样变性和溶解现象。

Focus on utilizing the gluts and not the quads.

集中注意力在臀肌而不是股四头肌。

Use proper stretching for flexibility including the hamstrings, quadriceps, gluteals, hip rotators and back extensors.

妥善运用弹性伸缩包括腘、股四头肌、肌肉、髋部及背部伸肌转子。
