Okay, now to the hips and the hip flexors eventually, and the quads.

现在来看看臀和臀屈，还有股四头。

For six weeks, participants performed a daily plantar flexor stretch, or calf stretch, of their dominant leg.

在六周时间里，参与者每天进行一次主腿足底屈拉伸或小腿拉伸。

The tibia nerve innervates the muscles of the posterior compartment of the leg, and intrinsic flexors of the foot.

胫神经支配小腿后肉，以及足固有屈。

You can lift it, but I like to lower, open up through the front of the hip, hip flexor.

你可以抬起膝盖，但我更喜欢放下去，髋前侧打开，打开髋屈。

Nice stretch in the quad and the hip flexors as you lift your heart, stand up nice and tall.

当你挺时，四肢和臀屈都得到了很好拉伸，保持好站立姿势。

It causes loose wrinkly skin in the flexor areas.

它会导致屈区域出现松弛皱纹皮肤。

It's caused by two things — tight hip flexors and weak glutes.

它是件事引起——髋屈紧绷和臀无力。

And when you get up, you realize that you need to stretch your hip flexor really really bad.

然后当你站起来，你发现你非常非常需要伸展你臀屈。

Get into a lunge and stretch your hip flexors.

弓步并伸展髋屈。

How does blood move through your systemic circulatory loop, to get from your heart to your champion right thumb-flexing muscle, the flexor pollicis brevis, and back again?

血液是如何通过你全身循环循环，从你心脏到达你右手拇指屈，也就是小指短屈，然后再返回？

These muscles include the flexor digitorum profundus which flexes the fingers at the interphalangeal joints, and the extensor digitorum which hyperextend them at the metacarpal phalangeal joint.

前臂群包括指深屈（在指间关节处使手指屈曲）及指伸（在掌指关节处使手指过伸）。

One muscle of each pair is called the flexor. It bends a joint and brings a limb closer to the body. The other muscle, the extensor, does the opposite.

每一对肉中一块被叫做屈。它可使关节弯曲并使这分肢体更靠近躯体。另一块肉即伸，作用相反。

He injured his hip flexor, the estimates of what that we don't have enough information on the injury, but the estimates you're seeing from, you know, injury experts out there.

他髋屈受伤了，我们没有足够关于受伤信息，但你知道估计是从伤病专家那里看到。

Also, there are nine flexor tendons which go to the fingers and the thumb as well as one nerve, the median nerve, which travels down the forearm and goes through the carpal tunnel.

管内还有9条屈腱与一条神经（正中神经）穿过，延伸到各个手指；正中神经从前臂发出经过腕管。

For example, the tack in your right foot ended up activating the motor neurons in your right hip flexors and hamstring, causing that knee to bend and your foot to lift up.

例如，你右脚图钉最终激活了你右臀屈和腿筋运动神经元，导致膝盖弯曲，脚抬起。

If you're on a higher couch, you can really use gravity to really open up through the hip flexors and get a nice quad stretch, and just kind of hold on to the back of your couch like so.

如果你在一个较高沙发上，你可以真正利用重力来打开臀屈，得到一个很好四头伸展，就像这样抓住沙发背面。
