Are there benefits in doing cardio more than once a day?

[Leander]

From what I've read on various post is the key of doing the long sessions to deplete the glycose and then the fat burning is acheived?

If that statement is true then pre-breakfast workouts should be much more effective than ones later in the day and that would also mean less time is needed to burn off fat reserves. Am I on the right path with this assumption?

some studies show that 300% more fat is burned when cardio is performed in the early am then pm. this is mostly due to the "afterburn" effect of the sustained metabolic rate after the long (60 min) cardio session.

A few more questions I'm a diabetic and I'm still learning what foods cause my glucose levels to increase. Yesterday I found out bannanas cause me to spike pretty high.

Anyway my question: is it harder for diabetics to lose weight and burn off fat? If the body does'nt begin burning fat until glycogen levels are depleted what hope is there for diabetics who at times deal with high levels of blood glucose? Should I stick with low carb dieting while trying to lose weight? (atkins, etc.)

i've been having a lot of success doing 20 min of HIIT following weight lifting on an empty stomach first thing in the morning... i certainly don't feel like i've lost any LBM (though i've probably lost a little, but strength is still up) and i know that i've been losing fat at a decent rate (well, diet helps too -- i'm on crum's diet but with a refeed day)... i've lost ~20 lbs in about a month...

wow Scruples, thats very encouraging thanks for sharing.


I'm curious about how much the metabolism is boosted by doing HIIT training. And does doing 2 sessions of HIIT mean that your metabolism is increased by twice as much?

30+30 does not =60 when it comes to fat loss.

I'll throw up the study when I find it.

Actually, the very idea that there is a fat burning 'zone' has come to be viewed by many as a myth.

Check out what Clarence Bass, no slouch on the subject of losing body fat, has at his site, geared towards HIIT anaerobic training:

Gives rather a different perspective, to put it mildly.

Again I totally disgree - to burn fat your hr HAS to be above a certain thershold. Period.

Interesting article Mjollner, in particular the 2nd link.


They suggest 6-8 sessions of 20 second intense cardio activity with a period of 10 seconds of rest in between. Each session gradually increases the oxygen intake. The overall result over a period of weeks is a signficant decrease in fat tissue while lean and muscle tissue is retained.



I may try this out and see what type of results I get.

We are not in disagreement. Did you read the articles? The methods specified in the articles definitely get the heart rate up above a 'certain threshold'.

I've tried the same protocols described in the links, and they have produced better results for me than long 'in-the-zone' cardio sessions.

Mjollnir have you tried that method out yourself? The one thing I found odd about the article was that they suggest only doing that type of training once or twice in a week. I'm wondering if its possible to cut down the amount of weeks needed for maximum results by training more frequently.
