I have tried using .CSV export and that works OK after a bit of fiddling about with import settings for Excel. I now have two very long columns titled IBI and CORRECTED. presumably these are the inter-beat intervals in milliseconds?

Thanks, jon</p> <p>Hi Jon - Tris from HEARTRATEMONITOR.co.uk says - not sure why your's isn't working. It would be corruption in the file. I'd suggest DELETING ALL files and make a TEST file of just a few minutes... download to TRAINING MANAGER and export to CSV format - then open it in Excel. If it doesn't work - then I'd consider sending the item back to the supplier ... this is a feature of the memory belt that does work well. If it doesn't it is either something you are doing wrong, or a faulty belt. Also make sure you have latest version of TRAINING MANAGER - visit Suunto.com then SUPPORT and DOWNLOAD area...

There is both these 2-second samples and the raw R-R. The raw data is at the end of the file as a long sequence of numbers. At first I thought those numbers were the same as the 2-second tabulated data higher in the file, but they're not. My apologies for the false claim above. I'd edit or delete my earlier posting if there was a way in this forum system. Best regards.

The data points in those files are always at 2-second intervals, but R-R is, by definition, at variable intervals. A true raw R-R data set would be a sequence of numbers indicating exactly when each beat was detected, regardless of when it came. The implication of this is that the data output by Suunto are interpolated values: somewhere (either the watch or TrainingManager), something is measuring the irregular R-R sequence, interpolating it, and then sampling the interpolated result every 2 seconds to produce the data actually written to the files. Why would that matter? Because the exactly approach is a critical issue for heart rate variability analysis. Interpolation and sampling can introduce bias and other problems. I would really like to know how exactly Suunto is producing the 2-second samples, but so far have not found information about that. Does anyone here know? (I would like even more to be able to get the real raw R-R, but that appears to be impossible.) @burr4: Thanks for that info; I was wondering how to read those .ste files. I didn't think it was so easy as just unzipping them! Best regards. Just a note: the R-R data provided in all of the Suunto file formats exported by TrainingManager are *not* complete R-R data.

High-intensity cardio intervals are performed in something we call heart rate training zones.

ow to get Raw data from Suunto file.

Step 1.
Right click on Suunto file to export in training manager. If you have many files, you can highlight all of them and export together.
Step 2. Save files to a location you will remember
Step 3. GO to the folder where you saved files and right click to look at properties. Where it says “type of file” STE….”opens with” click the change button and select your zip program file (i.e. winzip or zipcentral etc).

Click import

Rename the file
change columns (the HR, alt etc. is far right)
