I have a Forerunner 55s and am considering buying a few more. I want to use these to monitor the heart rate of a group of participants doing exercise. I can see the heart rate profile on Garmin connect and have also accessed the file system after connecting the watch to my computer. I have use the FIT SDK to translate each file into CSV and the idea was to upload these files into freewares such as Kubios. I have previously done this using the Polar watch and it was relatively easy. I have some questions that I would really appreciate an answer to:
Is there a second to second recording of heart rate available in the file system? I have searched the Activity, monitor and metrics files.
Is there a way of accessing data on how long each participant heart rate is in each zone?
Is it possible to get data for HRV without using a heart band?
Thank you
