Your own leg and arm movements in physical reality match the moves in virtual reality.

你在现实中的腿和手臂的动作与虚拟现实中的动作相匹配。

These might've helped them make powerful arm movements.

这些可能帮助他们做出有力的手臂动作。

In some experiments, the arm's movement was stopped short by DNA strands sticking up perpendicularly from the platform.

在一些实验中，手臂的运动被从平台上垂直竖起的 DNA 链短暂地停止了。

With all these arm movements, most of the rotator cuff muscles — like the teres minor or the infraspinatus — are acting like synergists.

通过所有这些手臂运动，大多数肩袖肌肉——如小圆肌或冈下肌——都像增效器一样发挥作用。

This might have to do with the limited ability of tracking specific exercises, especially intense exercises that don't require much arm movement, like cycling, or exercise that don't require much distance traveled, like lifting weights.

这可能与跟踪特定运动的能力有限有关，尤其是不需要太多手臂运动的激烈运动，比如骑自行车，或者不需要走太远距离的运动，比如举重。
