HeartRates & Health
By dcb on Dec 20, 2004
So I recently played Racquetball, for the first time in 8 years! I have been jogging some, so my heart is in pretty good shape. But RB stresses muscles you probably forgot you had! At least for me, it was serious wind sprints :-)
Being the electronics gadget collector that I am, I wanted to plot my heart rate chart during the game, and compare it to a recent jog. So I wore my Polar HR monitor. Racquetball, it turns out, sustained an elevated HR that exceeds my jogging! And three games totaled 41 minutes, or almost twice my jogging time. So, from a cardio perspective, this is a really good exercise. But I knew that :-). I've included the chart from my Polar HR monitor below.
The following link is a 5-page scientific report on the statistics of Heart Rate Recovery and how it correlates to heart disease and death. It is pretty intense reading. But the bottom line is that it found that a HR recovery rate of less than 22 "beats per minute" during the 2 minutes following intense cardio exercise, is a bad thing. My 2 minute recovery was 34 bpm for racquetball, and closer to 50 for jogging.
I'm guessing my jogging HR recovery is better than RB because my body is more acclimated to jogging (I've been doing that for a year now) than the wind sprints of racquetball. I stopped the watch before the 2 minute mark when I finished jogging, so I only show a 1-min recovery for jogging.
It is probably worth checking 2-minute HR Recovery every 6 months or so to see how the old ticker is doing.
