Cardio and fat burning question? (Intermediate-Advanced)?!
Question: Cardio and fat burning question!? (Intermediate-Advanced)!?
This question is what I'd call intermediate or advanced so I'm hoping someone in the field can help me here!. I'm studying to become a personal trainer and I just had this question:
The aerobic system burns the most fat; anaerobic glycolysis doesn't "burn" as much fat (it doesn't use fatty acids for the primary source of energy)!. However, if I'm on, say, a cycle and I'm exercising at 70 - 80% of max heart rate, or 80 - 90% (anaerobic) or max intensity, by definition I'm burning more calories (using more energy) but because my legs are exercising anaerobically, they aren't using fat for energy anymore!.
Does this have anything to do with losing fat in a practical sense!? In other words, by exercising at a lower intensity and burning less calories in favor of the aerobic system, am I actually cutting more fat or is it better to stick with burning more calories because that's what matters at the end of the day!? Thanks!.Www@Answer-Health@Com

if you are heart healthy forget about training in the "fat burning zone" that's 1980's science!. you want to exercise at around 70% of the VO2max or greater!. when the body uses primary glucose during the exercise session it will utilize more free fatty acids in the hours after exercise, where the real fat burning takes place!. hands down interval training is optimum for fat loss!. when you exercise at or near maximum effort there is maximum release of growth hormone (GH)!. GH is the most powerful fat burning substance that the human body produces!. t is also 2nd in it's anti-catabolic properties with insulin being the most anti-catabolic hormone!.
low intensity cardio has been proven time and time again to not be optimum for fat loss!. there are hundreds of medical studies in the subject!.Www@Answer-Health@Com

I would say calories is more important because your body continues to burn fat even after you have stopped exercising if you keeping your heart rate in a fat burning rate!. I think doing cardio at a high intensity will burn more calories get your heart rate higher and will take longer for you heart rate to slow, so you will at one point be in a fat burning stage!.Www@Answer-Health@Com
