Hi everyone, Does anyone know the effect of exercise on phe levels? I have a seven year old son with levels under 6 until recently when we had one just above. We're monitoring more frequently now and I'm curious to hear from anyone who may have been in a similar situation. I don't know if I should be an advocate for him to try to have him treated or not. I am also very curious as to the effect of exercise on phe levels and can't seem to find anything online. Essentially, my son ran a one mile race in very hot weather and afterwards, was very warm, of course. I know that fever can increase phe, but what about other things, such as exercise, that increase your body temperature. About 2-3 hours after the race he had a very tough time controlling his impulses and had erratic, wild behavior. I do appreciate anyone's comments. Thank you!
Exercise can effect phe levels. The way I understand it though is that it is not due to an increase in body temperature. Instead, calories are being burned just like they would be when your body is working hard to fight off illness. After those calories are used the body can sometimes turn to breaking down muscle to get energy. Because muscle is essentially made of protein, when this happens protein is basically being put into his blood stream.
Back in middle school when I started track and field I was told to drink formula shortly before becoming active, because my levels had increased a little bit. This gave my body a small boost of extra calories and phe-free protein to burn off while I exercised.
