As a professional there are three ways to measure load, the first two modes are explained here → Going for a smart run

1. Connect the sensor to the athlete’s phone

  • Pair the sensor with the athlete’s smartphone.

  • The phone must stay nearby during the run.

  • After the run, data is synced automatically to the app and PRO platform.

We recommend this if you want full follow-up of athletes, inside or outside the clinic.

2. Run phone-free with or without Garmin

  • Put the sensor in standby and start measurement on the sensor.

  • Sync afterwards with the app to upload data, which will be synced automatically to the app and PRO platform.

We advise measuring load this way if you want to follow-up the load of athletes in the platform, whether they are running in the clinic, or running outside. Especially if athletes don’t want to run with their phone.

However as a professional, it’s also possible to capture and visualize the data of a certain athlete, by using your own device (similar to option 1).

3. Use the expert’s device

Connect the athlete’s sensor to your own device and app. You have three options:

Option 1: Sign in with the athlete’s account

  • Data will be synced directly to the PRO platform under the athlete’s profile.

Option 2: Explore without an account

  • You can measure and visualize load in real time.

  • Data will not be saved.

Option 3: Use a generic athlete account

  • Create one athlete account (e.g. “Test Account”) to capture data from multiple patients.

  • All data will be stored in the PRO platform under this account, but not linked to individual athletes.

We advise to capture data this way, when you want to visualize the load data, or when you are using the OnTracx Lab function and you are not interested in saving the data.


✅ Perfect — now that you know all about measuring load, let’s dive into how to perform a load screening!
