Yeah. People are still going around and around. I think there are no absolute answers and of course it depends on what works best for the individual and the intensity/duration of the cardio.
When it comes to preserving muscle mass, and taking into account the above info, I'd definitely go with with you on that, Dave. And
As Lyle Macdonal said:
Quote:
Again, it depends.
Some people can train fine on an empty stomach, others can't.
What you need to do during:
low intensity cardio
vs.
high intensity carido
vs.
weight training
Is not necessarily the same either.
Optimal (in theory or in practice) pre/during/post workout nutrition is going to depend on a host of factors. Are there generalizations that can be made? Sure.
...It's lovely to think that nutrition and life is that simple and black and white but it's not. You can always find situationally specific exceptions to just about everything.

And another point:
Quote:
Seriously, no matter what detailed minutiae typse of arguments people want to make, any strategy that seriuosly harms your ability to work hard in the gym FAR outweights any benefit from doing something else.
That is, even if not taking in carbs pre and during workout improves seomething, if it means you can't work as hard, it doesn't matter. Everything else, hormonal crapola, nutrient oxidation and all that shit pales in comparison to anything that harms your ability to train effectively.

According to Christian Thibadeau (speaking of protein before)
Quote:
Thibaudeau: If fasted state cardio could potentially increase fat mobilization, it's also potentially more catabolic to muscle tissue. This is due to an increase in cortisol production during fasted exercise. Since cortisol levels are already high in the morning, this could lead to more muscle wasting than during non-fasted cardio.
In fact, cortisol levels could increase muscle breakdown and the use of amino acids as an energy source. This is especially true if high-intensity energy systems work is performed. If an individual uses lower intensity (around 60-65% of maximum heart rate), the need for glucose and cortisol release are both reduced and thus the situation becomes less catabolic.
I personally do believe in the efficacy of morning cardio, but not in a completely fasted state. For optimal results I prefer to ingest a small amount of amino acids approximately 15-30 minutes before the cardio session. A mix of 5g of BCAA, 5g of glutamine (yeah, I know that Dave Barr won't agree with me on this!), and 5g of essential amino acids would do the trick in preventing any unwanted muscle breakdown.
However, I'll also play devil's advocate and say that morning cardio won't be drastically more effective than post-workout or afternoon cardio work when it comes to fat loss. Personally, I prefer to split up my cardio into two shorter sessions (morning and post-workout).

Notice Thibadeau said If fasted state cardio could potentially increase fat mobilization....

If you act sanctimonious I will just list out your logical fallacies until you get pissed off and spew blasphemous remarks.
