Post subject:  Who rides with a HRM?

I stopped using my HRM with my old gps as I didn't like what it was telling me lol, but got a new ANT+ one to go with my new GPS. Put it on and saw I'm spending significant amounts of time in the 90-105% of max HR (based on age). I know that just means my real max is 190ish not 220-age, but have to wonder if working out to that level is good / bad or indifferent to getting more fit. I think if I really ever wanted to I could probably pedal myslef into unconsciousness lol, I had to slow way down after that 5 mins of max effort as I started getting tunnel vision / feeling light headed.

On the bright side the effort paid off with a bunch of PR's :) http://app.strava.com/rides/10961776

Huh - apparently it's really not a good idea to do that

Dizziness or Fainting
If you work at maximum heart capacity, your heart may have trouble pumping adequately to keep blood flowing through your body, particularly to your brain. Without adequate oxygen, you may begin feeling lightheaded and dizzy, and you could pass out. Fainting during exercise almost always requires a trip to the hospital for an urgent examination.
Heart Attack
Heart attacks have felled experienced athletes whose hearts did not receive adequate oxygenated blood to satisfy the extra demands taking place during vigorous exercise

Just make sure you are getting enough sodium, potassium and Calcium and you'll be fine. I think cardiac arrest occurs to athletes due to not having enough salts to trigger an action potential for the heart to beat. Muscle fatigue, cramps, lactic acid build up are all due to not having enough salts in the body, which are sweated out during exercise.
