Muscle is going to engage and generate energy first by using this phosphocreatine system.

肉首先会通过使系统来参与并产生能量。

The ones that are used first for short bouts of intense activity are things like phosphocreatine.

在短时间高强度活动中最先被利的能量来源是这类物质。

If you've only heard about creatine as a supplement, well, phosphocreatine actually exists on our muscles, and that's why people take creatine.

如果你只知道是种补充剂，那么实际上存在于我们的肉中，这就是为什么人们会摄入的原因。

In the previous episodes, I talked about the phosphocreatine system and supplementing with creatine, talked about beta alanine for kind of moderate duration work.

在之前的节目中， 我讨论了系统以及通过补充来增强其作，还谈到了使β-丙氨来提升中等时长运动的效能。

High bouts of effort, really intense effort, short-lived, seconds to minutes, but probably more like seconds, is gonna be this phosphocreatine, literally a fuel source in the muscle that you're gonna burn, just like you would logs on a fire.

高强度的努力， 非常激烈的 effort，持续时间很短， 几秒到几分钟， 但可能更接近几秒，这将是， 字面上说是肉中的种燃料来源， 你会燃烧它，就像你在火中燃烧木头样。
