moderate intensity cardio VS hIgh intensity for fat burninig

[TheShit]

I agree with Cuts. The next time you are watching the Olympics look at the sprinters then look at the marathoners. Then pick the body type you want, and your aerobic questions are answered!

 

[cleverlandshark2001]

Yeah, but champion runners at the Olympic level have that great genetic makeup anyway.
There is so much more that goes into that.
I say, if you are already doing HIT with the weights, do some moderate intensity cardio to burn mostly fats for fuels. High Intensity cardio will burn a greater amount of fat, but also a greater amount of stored muscle glycogen and protein.
Whatever......
I am just as confused.

Yeah, so why do champion marathoners at the Olympic level have virtually no muscle in their upper bodies then? They are supposed to have great genetics right? We are not talking about athletic ability here were are talking about 2 different training methods, and clearly long duration low intensity aerobics are highly catabolic. You body wants to lose mass so that it can run farther easier, so it breaks down the muscle for energy.

so if HIIT burns gylcogen for energy and not fat would it be ok to do on an empty stomach 1st thing in morning? what will we be burning since our glycogen is depleted? should we sprint after weight training? i mean how bout running on 5.5 incline and speed 5.0 for 25 minutes?? ithat shouldn be catabolic right?? help me out here lolol

CUTS is the only one who looked at real world results for the answer. Sprinters have better musculature and lower body fat levels than endurance athletes, who often times look like AIDS victims.

While Olympic level sprinters are the best of the gene pool, non-Olympic level sprinters still look better than endurance athletes. Take a look at the next major marathon participants, they do not have anywhere near the low bodyfat or musculature that sprinters do. This is a direct correlation to the type of exercise they do. Long distance endurance training eats up stored protein to a much greater degree than high intensity training, plus requires less calories per unit time than high intensity.

Also, why exercise for an hour and not benefit from a post training BMR elevation? High intensity exercise elevates BMR for hours, while low intensity does not.

 

[missyd143]

what hight intensity are u talkin bout ??? how fast? lol and is on an empty stomach good? or should i have sum sugar so i dont burnmuscle or breakdown muscle for energy

 

[TheShit]

Do HIIT training in the morning on an empty stomach. This will maximize your results. Do not eat for 1 hour following your HIIT training. Your blood sugar will be very low so your body will be using energy from it's fat stores. I recommend building up to 10-15 100 meter sprints. Be sure to warm up with about a 400 meter jog before sprinting. Do your 1st sprint at 60% of your top speed, your second sprint at 70%, your 3rd at 80%, and the remaining at 90% of your top speed. sprint 100 meters and jog back 100 meters then sprint again etc. Start out with maybe 5 sprints and work your way up to 15. I have gotten great fat loss results with this method, not to mention improved speed for the various sports I am involved in.

I'm in agreement with theShit. In my opinion and experience, AM-empty stomach HIIT is the way to go for fat loss without muscle catabolism.

 

[Hoffmeister]

I don't know, guys.

The idea behind AM empty-stomach cardio is the whole "fat-burning zone" thing. That after an overnight fast, your glycogen is pretty much used up, and that doing low-moderate cardio "fat burning" cardio at that point will get into the "fat-burning zone" faster.

HIIT will almost definitely use glycogen for actual "fuel". I would think that doing it in the AM on an empty stomach would probably be the MOST catabolic to muscle.

Again, what the studies above show is that the actual "fuel" used during exercise is pretty inconsequential to actual fat loss. Your body adapts; use more "fat" during cardio, and the body will burn more glycogen the rest of the day, etc. It's the rise in your BMR that HIIT can produce that is really effective.

Sprinters vs Marathon runners....

There's a reason for that. And the reason is, a bigger framed, mesomorphic person wouldn't be good at long distance running. They have too much weight to carry, and naturally more musclar people wouldn't be competetive against slighter, slimmer people.... and so smaller-framed people tend to become involved in and be successful at long-distance, while bulkier types try another sport.

It's not that marathon running makes you LOSE muscle.... I doubt any of the marathon runners we see on TV were ever big, and lost their muscle from running long-distance.

The way I see it, sprinters are usually pretty muscular.... they can maintain their muscle mass while doing intense cardio for short bursts, and they don't even do as much weight training as a bodybuilder. So I don't see why a bodybuilder would lose a whole lot of muscle from intense cardio if sprinters can keep it.
