Contentment, Complacency, and My Fitness Tracker

Where does being content end and being complacent begin? As an older athlete this question is just dogging me. The parallel question might be where is the line between being content and capitulating? These are both, of course, extensions of some of my recent thoughts on balancing the effects of relatively high intensity workouts with the countervailing effects on recovery, plus or minus injury.

There might be a more scientific answer to these, at least in so far as fitness is concerned, and it would come from of all places the fitness tracker world. As it turns out my latest tracker(s) have the ability to measure the beat-to-beat variation in heart rate (HRV). This measurement is a proxy for autonomic nervous system activity. A lower HRV means autonomic stress. If correlated with the previous day’s workout that would argue for either a lower intensity session or rest.

Is HRV ready for prime time? Well, world class endurance athletes and many professional athletes in other sports certainly think so. How about for us, the regular folks hoping to improve our fitness and along with that our health? Dunno. I’m impressed and frankly a little depressed to find that my HRV responded so classically to what was for me an intense WOD yesterday. For this to work one must have the discipline to dial it back if your HRV is low on a particular day (be content with your work), but also the discipline to ramp it up when your HRV is high (fight complacency and go to work).

In a busy life it is likely the second part that will prove the more difficult.
