ive read research done on this and most of it does say that about 20 min will use glyco stores then after begin tapping into BF
p.s> you cant take mags serious the info is for the neive, only worth reading is MD
Hollywood is correct. Every class I've taken and research I've read backs this. Overall, to lose fat you need to create a caloric deficit but in order to maintain muscle mass, you need to keep is in the -300 to -500 range and have a clean diet. But, if you go to the lab, there is a machine that tests what fuel your body is using. Cant remember the name of it, but we had to run it. Its based on a number scale with .5 being fat burned .7 being a mix and 1 being carbs/max threshold. It measures your VCO2 (oxygen/CO2 exchange and the ratio it exchanges). At around 75% of your functional capacity you begin buring carbs as your primary fuel. 50-70% you will burn fat, but you have to stay on the treadmill longer in order to burn your target amount of cals. Doesnt really matter if your do 60% for 45 min or 80% for 20 min, as long as you create the deficit. Me personally, I enjoy the 60% for 45 minutes for a couple of reasons. 1. i'm not planning on competing in a 5K and 2). It helps me to preserve the glycogen stores and prevent glycogen and protein breakdown!! (but if I have a short timespan to spend that day, I'll go with the 20min.
Yeah bro, it is a Metabolic Cart that measure your Respiratory Exchange Ratio. The article is right, you never utilize just one fuel source. You are always burning a mixture. However, this mixture is highly dependent upon intensity and duration. At lower intensities, you are burning a higher ratio of fat due to oxygen availability. It does in fact take several minutes for lipolysis to begin, because it is a slow process. . .Quote:

Do you ever think/read for yourself in any other media other than bb'ing magazines?
It just gets old refuting b.s. like this. :bs:
Magazine information is 99% of the time WHACK and is just placed there to take up space and sell products. This is pretty much COMMON KNOWLEDGE in the fitness industry.
~SC~
OMG - I won't even start on this one :p
What if doing the first 10 minutes high intensity to quickly burn of any carbs and then drop it down. Would this work on a highly carb restricted diet(like the cutting sticky in the diet forum)?
because i just got finished with finals and before that, i didn't have much time to spend on the boards.Quote:
