I see, I see. So does HIIT make up any of your depletion? I ask because I’m hesitant to do it on non carbup days. Thib thought that HIIT on a diet like the AD would start burning muscle… and I’ve heard such mixed opinions on it that I don’t know what to think.
He said, “If you’re not fat adapted.” That is a huge distinction that, if lost on you, means you really need to beef up on a lot of things. Start reading this thread from page 1. I did so; why won’t you?
No, he said [I do not recommend doing sprints on the AD because of the high chance that muscle will be used for fuel rather than fat.] That’s almost EXACTLY what Thib said when I asked him. And that’s almost exactly what I’ve read in countless other places.
I have actually only found once case where the study said FFA’s can be used for HIIT. All the others said that for HIIT, glycogen will be used regardless. That means that if our muscles are outa glycogen, their going to start using themselves to create more glycogen, since it can only come from protein or carbs. So later in the week when us AD’ers are super low on glycogen, sprints will most likely be using muscle mass from somewhere on your body to provide the energy needed.
California, please don’t bless me with anymore of your comments. Go do some sprints on friday afternoon for me instead.
I’m not taking sides in this, persay…but when I asked him if his cutting/fat loss program he recently posted here would be good with the AD, Thib said it would be fine, as long as one is fat adapted. And it includes long duration (two 20-30 minute jogging) as well as short duration (two sprinting) days.
Perhaps it’s better in this case due to the low distance/duration of each sprint? When I used to do HIIT, it was like 30 seconds running, 1-2 minutes walking…repeat 8 times.
But on his new program he has 30-60 meter sprints…with 2 minute rests. Much different than HIIT.
I don’t know exactly what the cut-off point is, but as I understand it, sprints of AROUND 10 seconds or so are primarily fueled by ATP.
However, HIIT utilizing 30 seconds or more preferentially tap in to glycogen (again, I am not sure of the cut-off point, but I believe there is a link between glycogen usage and lactic acid inducing exercises, ex: high reps).
From personal experience, doing either form of sprinting later on in the week is more difficult. However, doing HIIT with longer sprints (like the lactic acid inducing 30-40 second ones as espoused by CT and Poliquin for fat loss) late in the week (say, Thursday or Friday) is a trainwreck. Not only does the workout itself suffer, but so do you the next day.
Alactic HIIT, while also more taxing depleted, didn’t result in my feeling like a bus hit me the next day.
I’ve mentioned this earlier in the thread and I believe it’s a sound approach: for those dieting on the AD, 1 or 2 lactic acid inducing HIIT sessions early on in the week could aid in fat loss beyond the known that HIIT aids in fat loss. It would do so by depleting you that much earlier in the week, placing your body in primary fat burning mode that much sooner.
As a bonus, that you will still be having a regular scheduled carb-up should ensure that your metabolism isn’t dropping off too much from prolonged low-carb dieting.
