Have started to track my heart rate variability to keep an eye on my training load. I'm using "Elite HRV" on Android with my Wahoo Tickr HRM.
I've got 13 days of readings, and yesterday and today it's showing as "Your Sympathetic activity appears to be abnormally elevated. Consider active recovery and/or the Guided Breathing reading to enhance recovery" I did a HIIT session on Friday, Saturday's reading was entirely fine, Sunday morning's ride said much the same as todays, but with 6 rather than 4 on the dial thingy. I'm under a lot of stress at work, which is playing havoc with my blood pressure and resting heart rate, so I'm trying to work out:
Is this change in HRV lagging from Fridays HIIT ride, or is it more likely the stress from work?
