Edge540 Posted February 3, 2015 Posted February 3, 2015 Went and got myself a Garmin Edge 510 with HRM. After doing a fair bit of reading I calculated my MHR of between 165 and 172 depending which formula you use which according to theory means I should be riding in the low 140's on average. After my ride on Sunday I noticed my HR spiked to 183 briefly and I don't recall any part of the ride feeling like I was about to pass out. The rest of the ride averaged around 144. Are these sudden spikes normal and is ok to push the boundaries a bit?

Are these sudden spikes normal and is ok to push the boundaries a bit? The spike to 183 might have been an anomaly between the sensor strap and monitor and not an accurate HR reading. Calculating HR zones based on a Max HR formula is a hit n miss affair, it might be accurate and then it might not be…It’s more accurate to do a proper Max HR test or a sub max type test to determine your true HR zones.
DIPSLICK Posted February 3, 2015 Posted February 3, 2015 Spikes are normally contact issues, belt to chestA mate told me saturday he uses his polar strap with his garmin pick up apparently the polar strap has better strap pick up and they are interchangeable So he says just buy a polar strap at sportsman and put your garmin on it and spikes are over,
Tatt Posted February 3, 2015 Posted February 3, 2015 Training according to HR is brilliant. As mentioned, get it properly determined at the Sports Science Institute. Tom
BDF Posted February 3, 2015 Posted February 3, 2015 Sometimes the wind making your shirt flap against your chest leads to mis-reads of HR. Before you get all sweaty, the contacts don't work so well either. The best thing I find to prevent mis-reads due to this is to put a small amount of KY-Jelly on the contacts on your chest. Seems KY is good for many things..

Edge540 Posted February 3, 2015 Author Posted February 3, 2015 Thanks guys will go pick up the Polar strap and give it a go
WrightJnr Posted February 4, 2015 Posted February 4, 2015 +1 for the Polar strap with Garmin transmitter. Used that setup for over a year.
GlockG4 Posted February 4, 2015 Posted February 4, 2015 I found that using a formula to calculate max hr is almost never accurate. Doing a max hr test and a Lactic hr test is much better. I can ride for days on 168bpm but my partner(same age and build) has a max of 175bpm. My resting hr is about 20bpm higher than most of my mates, so i went to a cardiologist to get everything checked out, and he explained to me that everyone is different and there is no accurate formula for calculating these things. He also told me that caffeine should NEVER be used while exercising, that is what leads to heart attacks(his word not mine).

(eg: energy drinks, gel bar, etc etc). Caffeine is suppose to be a great source to provide a bit of a kick in your performance. The key is not to overdo it with the caffeine.
Guest Smimby Posted February 4, 2015 Posted February 4, 2015 Only use a formula to calculate HR when you are starting out as a guideline. Best is to ride hard and see what your max HR registers, that is your new max.Having a test done is the best. according to those "formulas" my max HR should be 178 but I can still get it to 190

An Heart attack is NOT caused by your HR going high, it is caused by BLOCKED artery. (but that could cause your HR to go high.....etc)
porqui Posted February 4, 2015 Posted February 4, 2015 A formula is just a rough guide - you need to be tested to get a better idea of max heart rate. You can't get a heart attack from caffeine - now don't go and drink 8 cups of coffee before a ride you will die from over hydration.

Caffeine is suppose to be a great source to provide a bit of a kick in your performance. The key is not to overdo it with the caffeine.I have no idea, I have NO medical knowledge, so I can not dismiss or confirm that, all I can say is that 2 GP's and a cardiologists told me that caffeine should not be used during exercise. I still take a powerbar gel with caffeine when the home/finish starts to feel unreachable. I know someone that took a VOOMA and his heart spiked to 221bpm on an easy ride, so I guess it, like most, depends on the ride.
Robrider Posted February 4, 2015 Posted February 4, 2015 You don't need to go to an institute. Do this test to find your LTHR and base your training on this. Note, this is not a max HR test, but a lactic threshold. Look on Joe Firels blog how to determine your zones from the result of yout LTHR test. http://www.joefrielsblog.com/2011/05/the-30-minute-test-is-easy-really.html I do the test on the trainer to avoid traffic and robots etc.
