Please Scroll Down to See Forums Below im goin to start doing on the treadmill 60 seconds sprint, then 60 seconds walk, then repeat cycle 10 times for a total of 20 minutes. My question is when to do these, with sprinting your body doesnt have enought time to oxidize fatty acids for energy so it relies on glycogen and proteins from muscle, correct? if this is so is there any benefit of doing thesse in the morning on an empty stomach, or would it even be better to do them later on in the day when you have a higher glycogen storage thus decreasing the risk of your body using proteins from muscle for energy???

Very good question...I think that surely someone should know the answer to this...
Is your goal to burn fat or to get into better physical shape?
Spatterson...what do you think?

You are only sprinting half of the time and only taking in account the energy requirements of skeletal muscle. During the 60 second walk you are beta oxidizing fat and your heart will beta oxidize fat at all times.
Depleting your glycogen stores is a possitive factor as the carbs you take in post workout are now more likely to be used to replenish muscle glycogen.
The true fat burning effect of interval sprints comes from the elevation of metabolism post workout and the hormonal impact intense intervals have on your body, not the calories or caloric distribution burned during the workout.

do it whenever you feel like doing them, but your BMR will usually be hypoed up to 6 hours later, so somewhere in the morning is a good idea to take advantge of this.
I do it in the afternoons myself.
Just don't do it in the mornings on an empty stomach like some people do. The body has a whole lot of cortisol flowing around upon waking. At least down a protein shake to stay out of a catabolic state.

Becarefull if you are doing them in the morn you may lower you muscle atp levels to much. You also get light head from a lack of fuel. It happened to me this morning and I almost busted ass on my way up the bleachers. Their was no warning just boom it hit me like a ton of bricks.
