# 耐力测试

了解如何使用自动采集的耐力测试功能来评估骑手能维持姿势多久

> **信息：** Sustainability Test（持续性测试）功能是随 Velogic Studio 的 Aero 模块一起引入的，但运行它并不需要正面摄像头；只使用侧面摄像头也可以。

Sustainability Test（持续性测试）功能本质上就是“定时自动拍摄”。它的用途是观察骑手在新姿势下能保持多久，直到某些情况发生变化，通常是由于疲劳。

要开始 Sustainability Test，请点击第 2 步中 Capture 按钮右侧的小箭头，然后点击“Sustainability Test”：

![Capture 按钮下拉菜单，显示用于自动定时拍摄功能的 Sustainability Test 选项](https://2529810062-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjxwtZYYk0lvusnMTywNR%2Fuploads%2Fgit-blob-dc9a3fc16ac082499ef5f1c3a5a69a99a1256f99%2Fsustainability-test-1.png?alt=media)

这将打开一个小型配置窗口，在其中你可以设置拍摄频率以及测试持续的时长：

![Sustainability Test 配置窗口，包含拍摄频率和测试总时长的设置](https://2529810062-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FjxwtZYYk0lvusnMTywNR%2Fuploads%2Fgit-blob-61a9689b158bd2bb1f0777f426597a452323dc23%2Fsustainability-test-2.png?alt=media)

当你点击 START 时，Capture 区域会变更，向你显示持续性测试进度的信息：\

你可以随时取消。每次拍摄完成后，系统都会自动以拍摄时间为文件名。

当测试完成后，你可以考虑使用 [拟合日志中的 Spark Lines](/zh/di-02-jie-shi-yong-velogic-studio/spark-lines.md) 来快速了解拟合过程中重要参数是否、以及何时发生了变化。

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.velogicfit.com/zh/di-04-jie-aero/sustainability-test.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
