HIIT and immune system?

[rooney111]

Anybody heard about if you do HIIT, you are compromising your immune system for a period of time? Is that true? Can someone please throw some light onto this issue?

When you work out, your glutamine level becomes lower and you become more prone to sickness, your wounds heal slower, etc. To prevent that, you need to take more glutamine. Very simple. Stuff like Vitamin C and Echinacea also works.

In a way yes, in a way no.

Not something for you to worry about. Ie, is much worse to be a couch potato for your immune system, than to exercise.
