UPDATE:

This plugin is deprecated and will no longer be updated.
Our plugin contributed to placing the Health and Fitness use case in the Outsystems mobile plugins roadmap, and in case you missed it, a new official plugin was released and you can find it here.
There is also documentation available, here, that can help you start using it on your mobile app.

This work was based on a Cordova Plugin that can be find on:
https://github.com/dariosalvi78/cordova-plugin-health

iOS devices: Require a provision profile with HealthKit access enabled.
Android devices: Require a digital certificate to enable the Fitness API. Follow the next link to find more information (https://developers.google.com/fit/android/get-api-key).
