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

如果你只知道是一种补充剂，那么实际上磷存在于肉中，就是为什么人会摄入原因。

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

肉首先会通过使用磷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用能量来源是磷类物质。

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

在之前节目中， 讨论了磷统以及通过补充来增强其作用，还谈到了使用β-丙氨来提升中等时长运动效能。

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.

高强度努力， 非常激烈 effort，持续时间很短， 几秒到几分钟， 但可能更接近几秒，将是磷， 字面上说是肉中一种燃料来源， 你会燃烧它，就像你在火中燃烧木头一样。
