" How is it that this implosion can be reversed into an explosion? "

“这样的向心爆炸是怎样被逆转变成向外爆炸的？”

And make sure you are indeed training to concentric failure.

还要确保你是在行向心失败的训练。

Because the centripetal force of Earth's rotation is stronger at the Equator.

因为地球自转的向心力在赤道处更强。

Is this the centripetal force in action?

这是运转时的向心力吗？

The other high tide you can think of is being caused by the Earth's centripetal force.

其它高潮你能够想象到是由地球的向心力引起的。

A 2016 study showed that subjects with multiple years of training experience who believed they were pushing to their max, end up making less gains than subjects that were directly instructed to push to concentric failure.

2016 年的一表明，有多年训练经验的受试者认为自己经达到了极限，但最终取得的效果比直接行向心失败训练的受试者要少。

Now there is a more scientific term known as concentric failure, where you fail to complete the concentric, muscle-shortening phase of a rep without significant compromises to your form or technique.

现在有一个更科学的术语叫做向心失败，的是你不能在没有对形式或技术做出重大妥协的情况下完成一个向心的、肌肉收缩阶段的训练。

Coming up is about concentric strength in the quads and glutes and endurance.

接下来要训练的是大腿和臀部的向心力量以及耐力。

To do so, Chae studied the statistical relation between the observed  centripetal acceleration of particles in motion and the expected Newtonian acceleration from the  distribution of baryonic matter in the galaxies.

为此，车了运动中粒子观测到的向心加速度与来自星系中重子物质分布预期的牛顿加速度之间的统计关系。

They say on average, the, whatever you can do, I remember reading on the concentric motion, you're, you can load four times more and I've tested it before.

据称，在平均水平上， 无论你能做多少，我记得在关于向心运动的阅读中提到，你可以加载四倍以上的重量， 我之前经测试过这一点。

That means this car, this reference frame, has a  centripetal acceleration which is directed in towards the center of the circle which is  to your right.

这意味着这辆车， 这个参考系，有一个向圆心（即你的右侧）的向心加速度。

If you had no tone in the legs, you would just flop into the ground and you would have to use concentric eccentric muscle contraction.

如果腿部没有张力，你就会直接摔倒在地，不得不依靠肌肉的向心和离心收缩来应对。

Dude, I see that stuff with, with box jumps where I got athletes who are running and they can't handle the concentric portion.

哥们，我看到有些人做箱跳时，运动员跑完后根本承受不了向心阶段的力量。

The inward component of the normal force alone is enough to provide the centripetal force required to stay on track.

仅靠法向力的向内分量就足以提供维持在轨道上所需的向心力。

And now everything that you put into it on a concentric force, it whips right back as peak concentric load.

现在， 你在向心力阶段所施加的每一分力，都会立即以峰值向心载荷的形式反弹回来。

So there was a meta-analysis recently where they looked at either concentric repetition of more than two seconds or less than two seconds and saw strength outcomes were better.

因此，最近行了一荟萃分析，他们了超过两秒或少于两秒的向心重复，结果发现力量结果更好。

With that much friction, micromice today can turn corners with a centripetal acceleration approaching 6 G's.

凭借如此大的摩擦力，今天的微鼠可以在转弯时达到接近6个G的向心加速度。

The steep angles help cars turn with less friction, because part of the normal force itself now points in to contribute to the centripetal force required.

陡峭的角度有助于汽车减少摩擦地转弯，因为法向力的一部分现在向内部， 有助于提供所需的向心力。
