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

现在来看看臀部和臀肌，还有股四头肌。

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

在六周的时间里，参与者每天进行一次主腿的足底肌拉伸或小腿拉伸。

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

胫神经支配小腿后部的肌肉，以及足部的固有肌。

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

以抬起膝盖，但我更喜欢放下去，髋部前侧打开，打开髋部肌。

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

当挺时，四肢和臀部肌都得到了很好的拉伸，保持好站立的姿势。

It causes loose wrinkly skin in the flexor areas.

它会肌区域出现松弛皱纹皮肤。

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

它是由两件事引起的——髋肌紧绷和臀肌无力。

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

然后当站起来，发现非常非常需要伸展的臀部肌。

Get into a lunge and stretch your hip flexors.

弓步并伸展髋肌。

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?

血液是如何通过的全身循环循环，从的心脏到达的右手拇指肌，也就是小指短肌，然后再返回的？

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.

前臂肌群包括指深肌（在指间关节处使手指曲）及指伸肌（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.

每一对肌肉中的一块肌被叫做肌。它使关节弯曲并使这部分肢体更靠近躯体。另一块肌肉即伸肌，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.

他的髋部肌受伤了，我们没有足够的关于受伤的信息，但知道的估计是从伤病专家那里看到的。

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条肌肌腱与一条神经（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，右脚的图钉最终激活了右臀部肌和腿筋的运动神经元，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.

如果在一个较高的沙发上，以真正利用重力来打开臀部肌，得到一个很好的四头肌伸展，就像这样抓住沙发的背面。
