CityCyclingEdinburgh was launched on the 27th of October 2009 as "an experiment".
IT’S TRUE!
CCE is 15years old!
Well done to ALL posters
It soon became useful and entertaining. There are regular posters, people who add useful info occasionally and plenty more who drop by to watch. That's fine. If you want to add news/comments it's easy to register and become a member.
RULES No personal insults. No swearing.
not resolvedExcellent thread. And I am much heartened (as someone who's effectively switched from cycling to running this year) that nutrition methods for ultras can include sausages and cheese.
(Is a light pilsner on the cards as well...?)
Had a play around with Veloviewer charts of one of my longer (but still very humble in terms of distance) runs. Maybe a slight downwards dip of HR over time, but a definite correlation between HR and grade that probably overwhelms it.
@Darkerside you may have as much beer as you feel appropriate when you have finished...
I thought I'd drag this thread, kicking and screaming, back into the light of day. I'm still very confused and waiting for an exercise physiologist to explain what's happening.
On yesterday's long ride, my average heart rate rose in the first few hours, was steady for the next 12 hours or so, and then began to decline. This decline wasn't unexpected, as I didn't eat all that much in small hours of the morning, and was kind of expecting that to happen. Pleasingly, after all the training I've been doing, it happened later into the ride than it used to.
However the trend of my heart rate curve exactly matches the trend of the temperature cure. Average heart rate rose as the day warmed up, then fell in the cool of the night. It's clear that my heart will be working harder when the weather is hot, but it wasn't that hot yesterday.
Would you expect ambient temperature to have a noticeable effect on heart rate during steady exercise? I know about 'cardiac drift' if you're working really hard, but I wasn't...
@Greenroofer, you're still going to have to wait for a physiologist.
Possible explanation here
Cardiac drift occurs for long term, moderate to heavy submaximal exercise, so you don't have to be working really hard. Stroke volume is reduced so a higher heart rate is required to maintain the same cardiac output.
Increase in air temperature means increase in blood flow to the skin to control body core temperature in addition to that to required by the muscles. Sweating takes water from the blood plasma and increases the blood viscosity affecting the stroke volume. Both result in an increased heart rate.
The human body is a wonderful thing.
Shame the article does not deign to tell us what to look for
@Murun it sounds like the Garmin told him that something was wrong with his heart?
Googling suggest aortic valve stenosis can manifest as a fluttering heart beat or a murmuring heart beat (an extra beat in between the beats)
Other symptoms - chest pain, tiredness
Seems mostly in over 60s, possibly related to a calcium build up
Dunno, only thing I can think of that a standard HRM would tell you is if your HR stayed abnormally high even after you had reduced workload. Though could just be fatigue
Garmin told him that something was wrong with his heart?
OK not Garmin, but Raymond Dufayel;
Si vous laissez passer cette chance alors, avec le temps, c'est votre cœur qui va devenir aussi sec et cassant que mon squelette. Alors allez-y, nom d'un chien.
Given the recent failure of my normal type of watch to respond to having its battery replaced, I bought a USB-rechargeable watch with an electric display which can also estimate heart rate via blood flow through the wrist in case it turns out to be useful to regain some of the fitness lost through not commuting (though I already know I have to just go for more runs, walks and cycles and bigger skips). It emitted a piercing alarm the other day for a reason I couldn't determine, which was different to the "estimated heart rate above this level" alarm which is just a double-buzz, which it was quite happily doing when I went for a run yesterday. It was annoying more for happening during the period when it's been told to keep quiet and stay dark in caase I'm trying to sleep, so might conceivably have been some sort of "can't detect any blood flow so you might be almost dead" alarm, though it should have been able to work out that I was still moving. Perhaps it was a "you're dead and someone is stealing your corpse" alarm. At least, by not being made by Garmin, it doesn't do that irritating blipping noise every time I stop or start moving.
