Chest and ab FAT

[Scotty the Body]

The other problem with your theory is that Protein from muscle is a more proffered source of energy than fat so if your doing cardio for an extended period of time, you can run the risk of cannibalizing muscle for energy.

Why do you think those long distance runners are so damn skinny compared to say a sprinter.

 

[Arnold]

either way I do not even think it relevant because you do not get lean from doing cardio, and when you do cardio for extended periods, as STB said, you risk losing LBM.

From a bodybuilding stand point (preserving LBM & getting lean) short duration (20-30 minutes), interval cardio of is best.

That sounds perfectlly reasonable!

Does doing carbio (for like 3-4 hours at a time) really destroy that much muscle and if so does it take away from strength?

yes, it's called catabolism.

True, but it does help if you have a hard time keeping your daily calorie intake lower than you need to maintain.

 

[Arnold]

well, you could reevaluate your daily calaroic intake then.

If you're trying to cut cardio can definitely help, but your diet is the key to getting lean. We have been over this about a hundred times here?

Could you explain in more detail what this means, how it works, and what its effects are? Do you loose strength or just get smaller, equally strong muscles? Lose some fast-twitch strength for slow-twitch strength? For example...

 

[Scotty the Body]

No, its more like a thousand times P

Personally, i do the cardio more for strengthening my Cardiovascular system then for burning calories.

Basically, when you combine 'endurance training' (aerobic), which stimulates the slow-twitch muscle fibers, with 'strength training' (anaerobic) which stimulates the fast-twitch muscle fibers, ultimately the body will remain in a heightened catabolic state, thus causing skeletal muscle atrophy and impaired strength gains. Slow-twitch muscle fibers are for endurance, not strength.
Aerobic metabolism may use carbohydrates, triglycerides and protein for energy, thus if you're on a 'cutting diet' where glycogen may be depleted in the liver and muscles, long durations of cardio will ultimately breakdown proteins (from muscle) for energy. Also, using short high intenisty work-outs and cardio can also result in increased hGH secretion.

huh ? Heightened state of catabolism causes skeletal muscle hypertrophy, while impairing strength? Might want to re-think that statement

Hey Prince, are you Low Carbing by any chance?

What does this mean?

 

[Yanick]

Hypertrophy = one of the ways we believe a muscle grows, in which the actual cells get bigger to adapt to the stress.

The other theory is hyperplasia, which refers to growth by division of cells.

However, the reason for the above post was because when you're catabolic, hypertrophy/hypertrophy don't occur. Prince's post contradicted itself.

Catabolism=atrophy/(don't know the term for opposite of hyperplasia)
Anabolism=hypertrophy/hyperplasia

oops, thanks for catching that...I meant atrophy.

How can getting tons of cardio and strength training cause atrophy?

 

[Arnold]

I explained it the best I can, do some internet research if you need further explanation.

How about "tons of cardio can cause a Heightened state of catabolism which can lead to skeletal muscle atrophy, while impairing strength".

sound better?

Oxford's defines atrophy as : the wasting away through undernourishment or lack of use.

So how does doing weights twice a week and doing a few hundred kilometers of cycling cause atrophy?

 

[Arnold]

now you're taking things out of context.

the original point I made was that extended duration cardio can lead to catabolism, and for someone interested in bodybuilding shorter, high intensity cardio is a better choice to preserve LBM.

do whatever you want.

 

[eastcoast]

This is true... shorter (20-25 mins) high intensity durations are better for burning bodyfat and still maintaining LBM ...

Undernourishment = supplied with less than the minimum amount of the foods essential for sound health and growth = Too few calories, which may come about from too much cardio.

Atrophy can also be induced by hormones in your body, such as cortisol.
