ECA and heart (cv) development

[paul allen]

When I use ECA on the cross-trainer or whatever my heart rate is aound 10-20 bpm more than normal for that particular level and rpm. e.g. I'm usually around 150bpm but when on ECA it rises to around 170, sometimes close to 180bpm. I know that this is the effect of ECA but my question is, does this build cardiovascular endurance as if I were getting my heart rate up to that naturally, or does the fact that it's ECA induced stop the heart from developing in such a way.

I know that if my heart were around there for 30 mins without any ECA it would get stronger, but what about on ECA?

I'm wondering for example that when I train without ECA whether my heart will be stronger (needs to beat less times per min) from the increased bpm or will just be the same?

does nobody have any thoughts on this??

good question, i'll bump for info

Not sure, but great question.

My guess is that because the physiological mechanics of heart contraction are driving the heart with or without the drug, the propensity for further adaptation does exist while using the drug to speed the heart. However, I'd guess that any advantage in regard to adaptation would be much more likely to occur due to either the users increased intensity or duration of exercise - not necessarily because of a small increase in heart rate for any given exercise level.

Consider this though. Herbal ephedra use has been correlated with a heart-attacking virus. Yep, you don't see it much in the news, but the studies are out there.

As a former cyclist and one that closely monitored my heart rate, I would have to say that you would be much better off endurance wise to get your HR up without ephedra. Think about it...I can give you an injection of certain drugs that will speed of your heart while you just lay there on the table. Now, is that endurance? No. Now, ECA will help you in some endurance such as taking it while racing and it will allow to train longer sometimes, but it will not help conditioning the heart. You are better off at 170 bpm and trying to work harder to get it up higher than at 185-190 bpm with ECA without the overload or work level.

PS: Karma is always welcome here.

Agreed.
