四头肌

And finally, if your quads are untrained and/or weak (unfortunately true for many students new to yoga), these muscles will not contract enough to prevent hyperextension and help protect the knee.

最终，如果你的股四头肌没用受过训练和/或比较弱（很不幸的是很多瑜伽的新练习者往往都是这种情况），那股四头肌不会足够地收缩以防止超伸和帮助保护膝关节。

The anatomical study was made on 10 adult cadavers. From March 1988 to May 1997,22 cases of anterolateral femoral flap were performed and follow up.

对10例20例男性尸体下肢标本进行解剖，观察股神经肌支的分布、数目和长度，及其与股四头肌各头的关系。

The purpose of this study was to examine the effcet of acute exercise and acute exercise after hyperthermic treatment on hsp70 and oxidative stress markers SOD and MDA At the same time, we investigated hsp70 response changes to exercise.

通过观察急性运动和热预处理后急性运动对大鼠股四头肌热休克蛋白70表达影响的时相性变化和氧化应激标志物超氧化物歧化酶活性和丙二醛含量的变化，探讨HSP70对急性运动大鼠股四头肌抗氧化能力的影响和股四头肌HSP70表达的应答性反应。

In training the computer system provided sequential stimulation to three key muscles groups(iliacus, quadriceps, shank triceps), In 3 cases with different level of spinal cord injury, the clinical application and curative effects were observed with this system.

锻炼每周进行3次，每次踏车10min，锻炼过程中，电脑控制多通道电刺激器在不同象限内顺序刺激双下肢的骼肌、股四头肌、小腿三头肌来完成踏车运动。在锻炼中记录自行踏车时间，并观察血压、脉搏的动态变化。

BACKGROUND: To reduce the morbidity of traditional quadricepsplasty for the treatment of severe arthrofibrosis of the knee, we instituted a treatment regimen consisting of an initial extra-articular mini-invasive quadricepsplasty and subsequent intra-articular arthroscopic lysis of adhesions during the same anesthesia session.

背景：为了减轻传统股四头肌成形术治疗严重膝关节粘连带来的不利影响，我们创立了一种新的治疗方式，包括在同一个麻醉期间，最初的关节外微创股四头肌成形术和随后的关节内关节镜下粘连松解。

The big picture is: hip flexors and quadriceps are contracting while back muscles and hamstrings are stretching.

拿下犬式来说，大概念是：臗部屈肌和股四头肌是收缩的背肌和大腿后膕绳肌是被伸展的。

Methods: The authors conducted medical record reviews and telephone interviews of 106 consecutive patients with ACL reconstruction using quadrupled semitendinosus-gracilis autograft from 2004 to 2006. Data included anthropometric measurements (height, mass, gender, and age at the time of surgery). Hamstring diameter was obtained using cylindrical sizers in 0.5-mm increments and recorded in the patient's surgical record. Correlation coefficients and stepwise, multiple linear regression were used to determine the relationship between the outcome variable and the predictor variables (age, gender, height, mass, and BMI). Independent sample t tests were used to compare hamstring graft diameter between genders.

从2004年到2006年作者对106名相关的采用股四头肌半腱肌-股薄肌自体移植重建前十字交叉韧带的病人进行了病历综述和电话随访，资料包括人体测量结果(手术时的身高，体重，性别和年龄)，腘绳肌肌腱的直径用计算机圆柱分检器以0.5毫米的增值测量并记录在病人的手术病历中，相关系数和逐步，多个直线回归被用来确定结果变量和猜测变量(年龄，性别，身高，体重和体重指数)之间的关系，独立样本的t检验被用来比较不同性别之间的腘绳肌腱移植物的直径。

Standard EMG was recorded at bilateral quadriceps femoris muscles, triangular muscles, sternocleidomastoid muscles and rectus abdominis muscles. Parameters studies included spontaneous activity ; duration, amplitude of polyphasic wave of motor unit action potential; pattern of recruitment.

EMG取双侧股四头肌、三角肌、胸锁乳突肌和腹直肌，检测项目包括静止时的自发电位，小力收缩运动单位动作电位的时限、波幅，大力收缩时的募集相。

Result: The amplitudes of quantitative patellar tendon reflex and maximal volitional contraction of involved limbs were statistically lower than those of uninvolved ones. The decreasing extent of amplitude of quantitative patellar tendon reflex was statistically lower than that of maximal volitional contraction of quadriceps.

结果：患膝股四头肌的最大等长收缩和定量髌腱反射波幅均显著低于健侧，而髌腱反射肌电波幅的减低程度则显著地大于股四头肌最大等长收缩肌电波幅的减低程度。

Methods Twenty SD rats were randomly divided into two groups. The left phrenic nerve or accessory nerve was transferred to femoral nerve by the vascularized ulnar nerve bridging in Group A and Group B, whereas the right femoral nerve remained the disjunction. The electromyogram and wet weight, throughput and section area of myelinated nerve fibers, and section area of muscle fibers in quadriceps femoris muscle were determined after 24 weeks.

大鼠20只，随机分为A、B两组，每组10只。A组：左侧行膈神经桥接带血管蒂的尺神经转位修复股神经手术，右侧切断神经不吻合，作空白处理。B组：左侧行副神经桥接带血管蒂的尺神经转位修复股神经手术，右侧切断神经不吻合。A、B两组于24周后观察股四头肌电生理、有髓神经纤维通过率及截面积、股四头肌湿重比、肌纤维截面积比等指标。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
