Fifty-five posts (this is #56), and I'm wondering: has anybody mentioned the possiblity that weight training leads to an elevated heart rate during subsequent endurance exercise due to an acute reduction in plasma volume?
Interesting.. You mean reduction in plasma availability or in plasma absolute volume?

....PS I should have mentioned Solar, these are fairly recent developments so I wouldn't feel too bad if you haven't come across them yet.
You know what. I haven't been in the business for a while now. These good old theories about causes of fatigue and ways to delay them, I kinda got them for granted over the time.
But I always knew that lactate was in fact producing energy, and that training in the presence of lactate was a good thing. I think that given these new theories represent a step toward the truth (probably just an other step
), the reason why this dramatic change of direction does not impact on the way we must train, is that our goal was, and still is, to get rid of the greatest quantity of lactate per minute, during the greatest possible number of minutes. In the good old days, we thought that we had to get rid of it, now they say that we need to use it to regenerate more ATP. Sounds like they now see the glass of water half full instead of half empty
I'm really gratefull that you took that new perspective to our attention.
But I still find that something does not add up
If you don't mind, I may have more of extra-questions
And BTW here are a couple of them
1) You said in an earlier post that adrenalin, among other factors, may be responsable for that mysterious heart rate increase when cycling after weight lifting. Can the same enzyme be held accountable for an heart rate increase when cycling outside on a road bike, 25 miles per hour with a group, as opposed to cycling on a stationary bike?
2) That extra workload placed on the heart, is it a good thing? What I have in mind is this : if I train 500 hours on a road bike, with a heart rate at let say,,, 5 extra bpm, can it have a positive impact on let say O2 economy?
