Intraday heart rate variation
It turns out it wasn't taking as long to recover from jogging as it seemed in my "Progress report" a couple weeks ago. Instead, I had experienced a general phenomenon: heart rates while exercising are typically much higher later in the day than in the morning.
Until now, I had only been tracking how my heart rate varied as a function of speed:
After reading the article, I plotted the residuals (differences between actual heart rate vs. the linear model) against time of day:
For a given speed, my heart rate is about 15 beats per second faster later in the day than in the morning.
After controlling for both speed and time of day, my records for the past couple of weeks suggest that I'm recovering just fine from each workout.
