Morning Cardio...

[Herc]

I've been reading the posts in "Training" and "Diet & Nutrition" and now I'm confused. Now according to my understanding of what has been said the followin is true:

1) Liver glucose is used up in approx 4 hours.

2) During aerobic exercise liver glucose or digested carbs are the perfered fuel of the body

3) In the absence of Liver glucose or carbs the body catabolizes muscle as the perfered source of glycogen

If that's correct when do you ever burn fat?

The body will use different sources of energy depending on levels of activity being preformed.
When you preform a cardio activity at a very high intensity, your body will more likely use muscle over fat for energy once your other stores have been used up as its a better and easier source of energy.
Thus, your better off performing cardio at a lower intensity level (not above 70% of your MHR) for maxim fat burn.

And also what TSB said.

Yes, the key word there is "trying".

But, unfortunately what he said is not really correct. Yes, cardio done in the "fat burning zone" burns more fat directly, but high intensity (Interval training - alternating high/low intensity)cardio is better for fat loss because it expends more calories and at the end of the day that's what matters. It's also better for cardiovascular conditioning as well as just about everything else cardio can do.

if you did cardio at a very low intensity, like easy walking, you would pretty much burn fat exclusively. but, the higher the intensity, the lower the percentage of calories burned using fat. however, the actual grams of fat burned stay almost the same, but you also burn energy from glycogen in ADDITION to the fat cal. these will come from muscle, if glycogenstores are depleted.

Ok mr. smart ass, SORRY, Interval training -alternating high/low intensity is better than just Lower intensity. HAPPY

Don't blame me becuase you don't understand a simple sentence.

Now as I was saying the method used will depend on the individual and what current level of fitness they posess. You don't prescribe interval training to a begginer who doesn't have the base to perform this.
Therefore it would not be the best in that particular situation.

I understood it. I started right in with interval training, no compliants from me. You can't go all out right away, but you can do high/low intensity intervals.

*** Judging from your own personal experience TSB, not others that you have worked with?
You obviously know that because it's fine for you doesn't mean it translates over to others.

Yes I realize this.

What I wanted you to do was explain why interval training wouldn't be a good idea to start with (it could be moderate/low intensity intervals, too...and progressively work up).

i agree with TSB, if you started out doing intervalls as TSB said (low/moderate intensity) you would make progress faster! you may not be able to do the moderate intensity for long, but you CAN do it for a minute.

*** What it boils down to is what is suited best for that individual at that particular time.

Maki you're starting to annoy me with your little vague statements that basically say nothing.
