# 姿勢功率 (Form Power)

**什麼是姿勢功率？**\
動作功率是跑步功率的一部分，與垂直振幅和步頻有關，並且會受到體重影響。

**動作功率為何重要？**\
動作功率越高，可能意味著相同速度下的代謝能量消耗越高。降低動作功率，部分跑者可能能減少代謝功率並降低自覺疲勞程度（RPE）。

**什麼是動作功率比 (Form Power Ratio, FPR)？**\
動作功率比 = 動作功率 / 總功率

**動作功率比為何重要？**\
較低的 FPR 可能代表更高的跑步效率，但我們不建議刻意追求特定數值。建議觀察趨勢，分析不同配速、強度和疲勞狀態下的變化。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://strydtaiwan.gitbook.io/stryd/master/stryd-metrics/form-powe.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
