“That’s because gymnastics, unlike swimming or long-distance running, is considered an “anaerobic” sport, one in which short, intense bursts of power are much more important than endurance.”

So far, so good…

“Thus, having lots of complex sugars stored up — the kind produced by carbohydrates — does not help a gymnast that much (???). Those energy spurts are best provided by a diet high in protein. (???)”

Of course, I assume that they mean fat + protein instead of only protein.

I have a question about glycogen vs fat use during short intense (anaerobic) 4 – 5 seconds exercise. Scientific literature refers to creatine phosphate and later glycogen as the main fuels in that type of exercise. Where does fat comes into play?

I read somewhere metabolics adaptations ocurrs and intramusclar tryglicerids are used instead glycogen. Can you give me some references?

Curiously, nobody asked you a similar questions to mine in this post.

Thanks

They obviously mean high in fat. Meat and cheese aren’t 60-70 percent protein as the article asserts, but are 60-70 percent fat. During anaerobic exercise glucose is used as fuel. Fat can be used only in the presence of oxygen.

Do you consider it to be bad for the body to overload on carbs when it’s used to eating low carb? Or does it have an evolved mechanism from our ancestors stumbling over honey?

I do think it’s bad for the body to overload on carbs anytime. See today’s post for the reason. But that doesn’t mean that I don’t do it myself from time to time. If you’ve been on a low-carb diet for a long time, it’s even worse because blood sugars generally go higher than if your are habituated to a high-carb diet already.

The various publishers own the digital rights. It’s up to them to make the books available digitally. I can whine, but there’s not a lot else I can do.

I’ll pass the message about Kindle along to our various publishers. Unfortunately, it’s not our call.

I was surprised the results were as good as they were, since they only used 1g/day.

You beat me to the punch. I saw this article in The Heart, but I haven’t pulled the paper yet. If it looks as good as the press report, I’ll post on it.

Anyway, II was more thinking about the downloadable stuff for things you said the publishers don’t like, such as kids’ nutrition on low carb or future subjects you’d like to write about more completely. They could be more than a blog post and less than a book, and could be updated at will.

Just do what everyone else with internet access does: surf the web to find every site that relates to your subject or profession and takes notes on every feature you like. Then use all those things as templates (which makes it different from copying…) and voila – new web identity.

Oh. Yes, I see what you mean. Problem with the ebooks, though, at least vis a vis the mainstream press, is that I get paid for what I write in the mainstream press. I don’t know if that applies to an ebook. At least not without appearing Colpo-like. As to the new identity, maybe I’ll start scrounging to see what I can come up with.

Find some way to suffer an injury that requires treatment with a steroid. When the steroid causes you to balloon up to 280 pounds, the kind, loving people at PETA will make sure your picture is everywhere and they will send faxes about you to every major press outlet in the country.

Oh sure, they’ll conveniently fail to mention that you were a lean, mean fightin’ machine before the injury and that all the weight gain was due to the drug, but never mind … everyone will know who you are.

By the way, my wife informed me that she saw a story on the news this morning about how some people are allergic to wheat gluten … the story ended with the reporter reminding the viewers to always consult with a doctor before giving up wheat products — because you will be missing all those important B vitamins and could suffer health consequences.

I guess that explains why Eskimos, Native Americans, and most people who ever lived just sat around being sick all the time.

The amount of critical thinking that goes into some of the things one sees in the news is jaw-dropping.

For me, if I’m basically sedentary, very low carb is very comfortable. When I got back to playing ice hockey all hell broke lose: I felt sick, tired, and slow in my games if I stuck to my diet. Now I’m on a break from hockey for a couple of weeks, but doing a lot of endurance exercise (run, bike, swim) and again just feel weak and sick if I keep carbs even close to what I manage when I’m sedentary.

I gather from commenters above that dietary fat takes care of this problem for some…that could be the case for me, too, I suppose (although I kind of question how (and how quickly) muscle glycogen stores get replenished in that scenario…) but I have no idea what to aim for and how to go about eating more fat. I also really don’t know what to aim for in adding carbs to a baseline low-carb diet, I feel like my nutritional understanding is very all-or-nothing.
