So I hear and see information about training the body to burn fat as a way to keep fueling your body with longer rides. If my body is trained to burn fat what does that really mean? Does it mean if I have a full glycogen level in my liver I would still skew toward burning fat because Ive trained my…

At various intensities, your body will burn a different ratio of glycogen to fat. If you train to increase your fat utilization, you simply skew that ratio more heavily towards fat. For example, if you were 50/50 fat/carb when riding at 80% of FTP, and you trained up your fat utilization, you may b…

Interesting. Thanks for the reply

One would have to write a book to give you a thorough response :slight_smile: One of the key adapations to endurance training is the shift towards more fat utilization at a given work load. See the following charts, carb and fat ox of trained and untrained subjects at repeated bouts around FTP: […

There was a very interesting new research paper published on two-a-days as you mention just a week or so ago: It’s out of David Bishop’s lab (who is a very well-respected and reputable scientists in the industry). Of course, this is just one study, but it supports what the current base of evidence…

My understanding is that it is possible that consciously training in a low-glycogen state strategically (ie. not all the time) might add the icing on the cake so to say. There is conflicting evidence as you say, and especially, I don’t think anybody has been able to show direct performance benefits. …

[image] Mikael_Eriksson: I don’t think anybody has been able to show direct performance benefits. studies by Marquet have shown direct perfomance benefits with “sleep low”. However, what bothers me is how “performance benefits” are measured in all these studies. A short ramp test. And someti…

If it is beneficial at longer distances I think a 40 minute TT is a really good performance test and a difference should be visible simply based on the fact that aerobic endurance has improved. Because even though we want to increase our ability to oxidise fat, we don’t want to decrease the absolute…

What really puzzles me is the relevance of a low-glycogen state. Necessary? And is it necessary to withhold carbs between workouts? Studies show conflicting results, one is cited in the thread above.
