Is there an online discussion group that specializes in exercise physiology questions? I would like to know if anyone has developed a spreadsheet that will take as inputs the VO2Max treadmill test results and do a calculation at each level of exercise about what percentage of energy was produced from fat and what percentage came from glucose.
When aerobic energy production comes from glucose, six O2 molecules produce six CO2. When aerobic energy comes from fat, the ratio of CO2 to O2 is 0.7. There are published graphs that allow you take the ratio of CO2 exhaled to O2 inhaled during a treadmill test and then infer the relative contributions of fat and glucose at that level of exercise.
Since all VO2Max tests include a reading of O2 inhaled and CO2 exhaled, we have this ratio for every level of exercise measured. I'm looking to find a spreadsheet that would then do the calculations on amount of contribution from glucose versus fat at that level of exercise.
I can develop the spreadsheet myself, but would prefer to use something off the shelf - and tested - if it exists.
