The high-frequency export from OpenField allows you to export the raw data from the accelerometer, gyroscope & GPS sensors on a player by player, activity by activity basis to CSV. This type of export is really only recommended for research purposes as for a typical session for a single athlete, the export can generate up to 750,000 rows of data.
Firstly a folder has to be created either on the Desktop or within My Documents,
Once the folder is created, right click on the Player from the 'Active Players' and Export High-Frequency Data:
Then toggle 'Flatten Parameters' and 'Pad Time' to 'On':
Find the CSV export in the folder you created:
