like i said cardio before or after weight training? and why?
There aren't any professors here to my knowledge only PhD's and MSc's (I don't count undergrads or BSc's).Plus if you weight train before cardio you burn off most of your muscle glycogen so technically your body will be required to use stored energy (fat) to fuel itself.
This isn't exact science and I'm sure one of the professors on this site will correct me.

After, to put it rather simply. Weightlifting is an anerobic exercise meaning you rely on your quick energy sources such as Creatine Phosphate and Glucose or Muscle Glycogen. If you do cardio you will expend most of your stores of muscle glycogen and will be less efficient in the weight room. Also, after you expend your muscle glycogen and creatine phosphate stores your body will more readily turn to its Aerobic cycle and turn to fat oxidation during your cardio after training.
The point of weight lifting (unless your dieting) is to stimulate hypertrophy, you cannot do this if you exhaust your immediate or quick energy sources on cardio.
Nice post man.
However, some things I'm confused about that I am NOT arguing just looking over I guess.
First off: there are 3 energy systems the body uses. The phosphagen system, anaerobic glycolysis and aerobic glycolysis. When you weight train or do any other form of intense exercise, the phosphagen system is what's used first (creatine phosphate) because it's quickly enabled yet quickly depleted. However, it recovers. ATP is returned after 40-90 seconds and is ready to be used again. For instance, a sprint. Fast burst of energy, a peak then you slow down.
Glycolysis is the breakdown of glucose. During a time phrase that you run out of ATP the body turns, of course to the stored glucose. Anaerobic, being that lifting is anaerobic in nature, used anaerobic glyc second. Following that aerobic glyc. Each "step down" takes longer and longer to recover and replenish.
So my point that I'm confused about:
What you deplete during pre workout cardio is glycogen. When glycogen is depleted or low, the body will break down primarily proteins (AA's) into glucose, then pyruvate, the Acetyl CoA, etc to provide energy. THEN glycerol.
Am I making sense? Maybe I have it a bit wrong? Could def. be. After an interval cardio session, fax oxidization will happen to fit the replenishment of glycogen post workout.
Thought anyone?
Thanks.
Thanks for the reply Braaq. There's a lot I don't understand right now, but I bookmarked this thread to review and learn. I didn't mean to be a mental masturbator, I just wasn't sure if I made sense or if I was right. I'm young and am for sure stll learning. Nothing meant by it. I've always heard it as aerobic glycolysis at my board so I guess that's why I referred to it as that here.
