Sorry it took me so long to respond, I've not had a chance to be on the forum much lately.

I have heard that brief hypoxia can have cardioprotective effects, however you have to understand that nitric oxide is not a bad thing; Nitric Oxide is a substance which causes the blood vessels to expand in response to a buildup of ****bolic byproducts. For example; when someone who has angina pectoris has an angina attack they typically take pre-prescribed nitroc oxide to open up those coronary arteries.

The adaptations (which were not named) would probably not benefit anyone who is aerobically trained. Basically they tied a string around the vessels in the dogs' hearts and gave them angina attacks.

The whole hypoxic training thing works on several principles in different situations (for athletes that is).
In swim hypoxic training it's two-fold; you need to improve your ability to produce and utilize lactic acid through the anaerobic portion of glycolysis, and you have to get confident in your ability to hold your breath and work under water. I am a certified scuba diver, and a lot of people once water gets in their nose, they simply panic and cannot breath. Much like when you time your breath holds you may not be able to hold your breath as long under water at complete rest simply due to the psychological factors. You look at SEAL and PJ candidates who pass out under water, it's because they have the confidence but not the physiological capacity to complete the task.

Then, for non-water type activities the principle is actually Train Low, Live High. You need to train where there is enough oxygen for you to truly stress yourself cardiovascularly but live in an environment where you force your body to produce more RBCs so you can work harder at low altitude. Most peole can't commute down 6000 feet, so they just train and live high.

Why is "M E T A" censored?

If you're not going to fight with it on your face, why train with it? I just don't see the point of restricting oxygen than won't be restricted during the fight. It seems as if it would have negative effects for your training, not being able to do it at 100%.

Thanks for chiming in, Dan.

I was wondering if anyone was going to pick how nitric oxide was coined "toxic". I wasn't quite sure why that was labeled that way, either, but I'd be the first to admit I'm not completely up to speed on reperfusion pathology. We regularly administer nitroglycerin to dilate coronaries, via sublingual and intravenously. I know metabolic byproducts can cause nasty reperfusion arrhythmias, I didn't think nitric oxide was one of them.

Have you had any personal experience with hypoxia training? Other than the altitude tents and masks, what are your thoughts on restrictive devices? Worthless? Useful?

It's blocked because of previous hack attempts. Annoying in the training forums, since metabolism and metabolic is thrown around frequently.

are there options for sleeping high other than the 5000 dollar tent of financial doom

The actual nitric oxide isn't what is toxic, the article said that nitric perioxide and superoxide were the toxic products, nitric oxide itself may be toxic in etraordinary levels, my guess is that those are byproducts or the result of improper formation due to lack of appropriate substrates.
Let's keep in mind that even O2 (breathable oxygen) is toxic to humans in too high a level, and O3 (ozone) is downright toxic.
