Fitness Metrics

Ok I’ve pretty much perfected the following exercise program: work out just enough as to always stay sore but not enough to make any real progress. I had an interesting discussion today in the surgeons lounge with a cardiologist regarding fitness metrics. He was asking me about tracking fitness metrics during the course of a training year/cycle. He is pretty savvy and the Apple Watch has revolutionized his practice in that what would previously require a Holter monitor now only requires a stylish wrist watch and his patient’s can send him a text anytime with their heart rhythms. Pretty cool. But what about fitness? What metric do you use to capture that tidbit of data.

Here are the data contenders

  1. Results- Can’t argue with a WIN! Race results are a nice way to record progress from year to year/race to race.

  2. Period Track Test- For instance, You can perform a standard 20 minute warm-up run followed by 5, 1 mile intervals with 1 minute rest. Add some Heart Rate data and you can come up with an approximation of your heart training zones

  3. TSS- Training Stress Score- originally used in cycling to quantify the duration and intensity of workout. This is then used to calculation Fitness (CTL) and Stress (ATL) in programs like Training Peaks

  4. Lab testing- VO2Max, Lactate Threshold (involves period blood draws during exercise (typically a swim or ride), etc.

For the recreational athlete, the first three are more than adequate
