How is Lipid Oxidation Rate Measured?

#1

How was the lipid oxidation rate measured in the FASTER study?

I am interested in burning more fat per minute while running.

Here is a link to a study:

Can you post a link to the FASTER study? This way folks in this forum can look into it and help.

I received this in an email today after I asked about this from a sports lab in Calgary:

Absolutely we can help - this is one of the pieces of information we get from our VO2 max tests.
These can be done on the bike or treadmill and we take you up in 2 min increments to anaerobic threshold and 1 min thereafter to max.
We can tell from the gases you breathe out the % of fat/carbs at the various levels.
The cost is $199 and we need about 90 min to allow time to warm up prior and then to be able to go over the results afterwards.

Here’s a description on how VO2max measurement is performed. I think this is what you were looking for?

I am more interested in the amount of fat relative to carbohydrate that is being burned during different levels of exertion - like the Volek study. However, I’m happy to learn that this is easily done with breath analysis during a VO2 max test and does not require anything more invasive or expensive.

There are more invasive techniques, where a bit of muscle tissue is extracted. But, certainly inline breath analysis avoids invasive sampling.
