I went for a 40 kilometers ride today and the ride involved a fair bit of rolling hills. An interesting observation was that at the top of the hills my heart rate was nearly 20 bpm LOWER that when I was walking around my apartment or just standing around talking to someone.
Anyone else experience similar drops in heart rate whilst exercising compared to their normal heart rate? Cheers |

If it's a smart watch, you need to pay attention to the angle of your wrist. I use a watch like that generally but not specific to cycling. So I tend to leave it on when riding. To track my cycling heart rate I use a chest strap. I know that the watch is not very accurate with my wrists bent in cycling position. |

Anyone else experience similar drops in heart rate whilst exercising compared to their normal heart rate? Cheers Your cardiologist will likely tell you that Heart Rate is directly equated to energy expenditure. There is even a formula for heart rates that used to be a common measurement of "out put". The basic maximum rate was calculated as 220 - age in years and then percentages of that number were used to indicate output: Zone 1 = 50 - 60% Maximum For long, easy rides, to improve the combustion and storage of fats. Zone 2 = 60 - 70% The basic base training zone. Longish rides of medium stress Zone 3 = 70 - 80% For development of aerobic capacity and endurance with moderate volume at very controlled intensity Zone 4 = 80 - 90% For simulating pace when tapering for a race. Zone 5 = 90 - 100% For high-intensity interval training to increase maximum power and speed -- Cheers, John B. |

If you want even more confusion your cardiologist will tell you that there is "heart rate" and then there is "pulse rate" :-) -- Cheers, John B. |

Anyone else experience similar drops in heart rate whilst exercising compared to their normal heart rate? Not exactly what you asked, and probably won't explain your experience, at least not fully, but: https://en.m.wikipedia.org/wiki/Skeletal-muscle_pump My /perceived/ experience is that my heart rate continues to rise well after I crest a climb, and indeed may jump upward right as I ease off at the crest. This could all be me hallucinating; I've never followed it really closely with the HRM. If my perceptions are indeed correct, my best-guess explanation is that while climbing, my leg muscles are doing a lot of blood-pumping. When I coast at the crest, the "muscle-pump" shuts down and blood pressure drops a bit, stimulating heart rate to rise. Mark J. |

When I coast at the crest, the "muscle-pump" shuts down and blood pressure drops a bit, stimulating heart rate to rise. Is that how the control loop works? Obviously heart rate doesn't *just* depend on blood pressure, because pressure rises significantly during exercise. I would have guessed that the heart is roughly a positive displacement pump, and the heart rate is more or less proportional to the amount of O2 and/or CO2 that need transporting. How your body figures that out I don't know. It seems possible that the pressure setpoint is somehow set by metabolic requirements, do you know if that is the case? |
