Is it true that......

[JUICESEEKER]

weight lifting burns glucose, and cardio burns fat?

 

[Nutri-Wrestler]

they both burn glucose. after a while, your body will resort to burning off fat once glucose and glycogen are depleted

what nutri said

 

[JUICESEEKER]

so if the body will burn fat after glucose is depleted, will a high protein, no carb and fat diet best for fat burning. Or will the no carb diet make me lose muscle?

 

[JUICESEEKER]

BUMP. Somebody give me an answer, this is a legitimate question.

Glucose, the precursor of muscle glycogen, is essential for high intensity anaerobic exercise(weight training). The body cannot supply enough oxygen to produce the fuel needed for high intensity muscular contractions. In order to manufacture fuel for weight training the body must use a fuel source that does not necessitate oxygen to be utilized. Glycogen fits this bill. Whereas fat on the other hand requires oxygen to be utilized as fuel. With no muscle glycogen you are driving on an empty tank while trying to lift. Low intensity aerobic exercise can use fat efficintly as fuel due to the ability of the body to consume enough oxygen to use that fuel. This is the prefered energy use in various situations.

Rest- mainly fat
low intensity aerobic exercise- mostly fat/some glycogen
medium intensity aerobic exercise- about equal parts fat and glycogen
high intensity training- glycogen

Without adequate muscle glycogen you will be very limited in your ability to train. You just don't have enough gas in the tank to get anywhere. Your original assumption was correct....Weight training burns glucose(glycogen) and cardio burns fat in a higher percentage than glucose.

protein can also be converted to glucos once certain fuctional groups are stripped of, such as the amine group.

that should have been posted under my name. Damn grafix-GNC
