Pacemaker tuning for mountain biking
I am a 71 year old mountain bike enthusiast but I can't keep up with my friends anymore. I had my pacemaker put in about 5 months ago. After the initial disorientation I started taking data on heart rate during my rides (apple watch). I felt that my heart rate was too low (130 bpm) during steep pitches. Gradually we've increased that over the months to 150 bpm with the slowest recovery time possible and supposedly a pretty sensitive to motion response. I am learning how to "fool" the pacemaker with unnecessary upper body movements to get the rate up. But, in my data collection effort I am seeing that the higher I keep my heart rate the slower my times on a known circuit. Do I have the reslationship between heart rate and muscle power output confused? Should I dial back on worrying about heart rate and just relax? I would like to get back to keeping up with my friends. Thanks for advice.
