You can see it here:
Unfortunately, when I got on the bike the monitor stopperd working properly: apparently, it cannot stay behind me. After the crash, the numbers on the monitor are not much legible. On the original video they are a little better; after the crash the rate started from about 175 and decreased until about 165, at the end of the video.
With the monitor working properly, installed on the handlebar, I reached 176, IIRC. It was for sure more than 170. While running, I reached 203 after about 10-15 minutes and I was pushing hard but not at my maximum.
First, thanks for those numbers and that crash looked a little gnarly with your foot hung up on the bars ... laying a bike down like that is about the safest way to crash I think but I ~always want separation from the hunk of metal called the bike. I've also got a pair of that brand of boots (not quite so flashy though) and for ~$200, they have been a very good boot.
I might have missed this point but what are you trying to accomplish with the monitor mounted on your bike like that?

Been trying to remember my
Heart
Rate numbers from yrs gone by to compare with your numbers in order to make sense out of what might be happening. Its only been ~15 yrs ago that I lived this stuff as a runner. Needless to say, I'm drawing a few blanks .. Crossing over running to biking is a little interesting to me ....
The one thing that sticks out to me is the ~165 number you are obtaining while riding ... If you look at the 205 number as your top heart rate, that puts the 165-170 beats per minute very close to that 80%-85% of that MAX rate. That means, you might be sitting right at your anaerobic threshold. Maybe over it... slightly. This is the level at which lactic builds up in the bloodstream and forces muscles to slow down. This happens in all humans.
All Humans, gene dependent of course. Lactic acid was identified in the
1800s and it is understood but no cure for it other than tolerance through training to deal with it.
Next thing is your HR when you sat on the bike - 137 beats per minute? Sounds high also unless you were just doing something to drive it upwards. It is 100% possible, I'm way off base here on all this, but I don't think so. I hope to purchase a HR monitor in the near future and look at my numbers.
Its so hard for me to comprehend how riding a motorcycle can drive a heart rate up so high without near the actual physical work as compared to running or cycling ... I gotta get a monitor to see how hard my heart is working out there ... At this moment in time, it seems I'm on cruise control out there with my HR low (120-130 beats per minute?). I'd like more education on this subject.

I put an Eli Tomac interview out here in another forum .. He said there was a point in the Phoenix race where he and KR94 got gassed ..maybe mid way in the race... Gassed? You can't really see it but maybe the lap times show it. Gassed? He probably means they pushed too hard, went anaerobic, got lactic acid build-up, and had to drop their pace or effort back to a level their bodies could deal with the lactic acid build-up.
Remember when aerobics hit the states? Its nothing more than easy work for your heart and body. Easy work with plenty of oxygen present in your blood. Plus it is promoted as fun and it is fun for many people. Anaerobic work is not for everyone. It is hard, it is work. It is not fun and can be painful but going to a race and waxing others or your best times makes it all worth it. Injuries happen much more easily out there also at these levels.
Anaerobic threshold (AT) is a frequently used term that sometimes causes a little confusion. What is the AT and how can you use it to run faster? For starters, the AT is an extremely reliable and powerful predictor of performance in aerobic exercise. To explore further, I will begin with a brief, oversimplified, review of physiology. Muscles can "burn" glucose two ways, aerobically ("with oxygen") and anaerobically ("without oxygen"). Both systems generate a temporary energy store, called ATP, which in turn produces mechanical work. However, there are some major differences.

Thanks again for those HR numbers to play with. I'd always just thought bike riding was pretty much all aerobic but maybe not.
