First of all I am posting this here because this forum gets the most traffic and I cant think of another forum more appropriate so if someone wants to move it feel free.
Now having said that I had a seriously interesting day to day, I made an appointment at a sports science clinic for a body composition test as well as a fat burning range test. I have always been interested in the fat burning thing as there are so many opinions on what is optimal.
First of all the body fat test consisted of the caliper test across 6 sites. As some of you may know I am 54 years old and I am on 250mg Test E a week permanently, I workout four times a week reasonably heavy and I do NO fat burning or cardio at all. I was staggered to find that my BF came in at 11.4%. Now I have love handles, not huge but enough to piss me off and I had always assumed I was around 20% !!!! My Somatotype is Mesomorph.
The next thing that amazed me was the Fat Burning Test they do. They put you on a running machine for 9 mins with a mask hooked up to a computer. They then start you walking and the machine can actually measure at what heart rate your body starts consuming more fat than carbohydrates. I was amazed to find the the optimal heart rate for me is between 73 - 82 BPM !! I am sure my heart rate gets higher than that when I take a dump !!
I think this is a great test for Bodybuilders looking to find the optimal range for fat burning. The Clinic were insistent that this be done on an empty stomach, but not necessarily first thing in the morning. As long as you have not eaten for at least two hours you will get the maximum benefit.
