Early cardio

[dinho10]

Hi guys, ive searched and found some similar threads to my question, but not exactly, so here it is:

Who here that does cardio first thing in the morning (not lifting, just cardio) takes something before. I was taking a scoop of whey in some water and then doing about 45 minutes (usually 10 minute warmup jog, walk/sprint for 15, 15-20 cooldown jog). Also, how crucial is it that its whey, would i go catabolic if i were to just eat a piece of chicken since it takes longer to break down? Could i do it with nothing at all? My goal here is to trim the fat, im on 250mg test and 300mg mast per week, so with this am i STILL gonna go catabolic if i digest nothing before the cardio? Also, do u still think its ok to hit up some cardio post workout (which is in the evening) along with the morning cardio, or will it most likely lead to overtraining (i know i know, listen to my body...).

Let me know what you guys think, any input/opinions is appreciated.

the whole point of doing cardio first thing in the morning is that your body has used up muscle glycogen over the night. you are burning fat as the fuel source by doing cardio on an empty stomach.

by having a scoop of whey you are raising blood sugar and thus sabotaging the fat burning process.

My whey has only only one gram of carbohydrates. How would that raise the blood sugar to any noticeable degree? ATW brand

protein itself raises blood sugar. no carbs or fats needed. cardio first thing in the morning only makes sense on an empty stomach. otherwise you could do cardio anytime.

Ok, thanks Bouncer, makes sense. Following the early cardio, do u think whey would be best or a lean meat?

either or really.

fasted cardio for fat burning is a myth - have your whey before you go - it will bring your body out of the catabolic state induced by sleep and lower cortisol levels which are highest upon waking.

if you keep your intensity between 59 and 64% of your VOmax you will maximize fat burning.

Curious to why you say it is a myth. If you body has no carbs in its system, fat is broken down for energy. So how is it a myth? If you have anything I can read on it, I would love the link.

false.

while you are correct about whey bringing your body out of a catabolic state you are over looking the fact that it will slow the fat burning process for that particular cardio session.

Ill try going on nothing for two weeks, if im happy with the results ill keep it up, otherwise ill try it with whey. It just seems more logical that having nothing would be better if im keeping it to a 45 minute session, i think if it were an hour or more then a scoop of whey may have a benefit.

I have had good results with both approaches - too many variables were involved when I made changes for me to say which one worked best. However, my clients do just fine on an empty stomach - the only time I would advocate whey before am cardio would be if you're trying to make lean gains...

Effect of training in the fasted state on metabolic responses during exercise with carbohydrate intake.

Skeletal muscle gene response to exercise depends on nutritional status during and after exercise, but it is unknown whether muscle adaptations to endurance training are affected by nutritional status during training sessions. Therefore, this study investigated the effect of an endurance training program (6 wk, 3 day/wk, 1-2 h, 75% of peak Vo(2)) in moderately active males. They trained in the fasted (F; n = 10) or carbohydrate-fed state (CHO; n = 10) while receiving a standardized diet [65 percent of total energy intake (En) from carbohydrates, 20%En fat, 15%En protein]. Before and after the training period, substrate use during a 2-h exercise bout was determined. During these experimental sessions, all subjects were in a fed condition and received extra carbohydrates (1 g.kg body wt(-1) .h(-1)). Peak Vo(2) (+7%), succinate dehydrogenase activity, GLUT4, and hexokinase II content were similarly increased between F and CHO. Fatty acid binding protein (FABPm) content increased significantly in F (P = 0.007). Intramyocellular triglyceride content (IMCL) remained unchanged in both groups. After training, pre-exercise glycogen content was higher in CHO (545 +/- 19 mmol/kg dry wt; P = 0.02), but not in F (434 +/- 32 mmol/kg dry wt; P = 0.23). For a given initial glycogen content, F blunted exercise-induced glycogen breakdown when compared with CHO (P = 0.04). Neither IMCL breakdown (P = 0.23) nor fat oxidation rates during exercise were altered by training. Thus short-term training elicits similar adaptations in peak Vo(2) whether carried out in the fasted or carbohydrate-fed state. Although there was a decrease in exercise-induced glycogen breakdown and an increase in proteins involved in fat handling after fasting training, fat oxidation during exercise with carbohydrate intake was not changed.

please have a look at the quoted study and let me know what you think - thx

as fog pointed out, so many different variables are at play. if the goal is strictly fat burning cardio should be done on an empty stomach.
