I just read this in an old forum and it kind of disturbed me. Is it possible for this to happen? Are there any other ways to cause this kind of dammage? What if you have done this and don't realize it, is there any way to know if you have done this? what symtoms might show up? As for me I'm kind of stubborn and have done intense work outs while sick...paid for it later too.
Riding with flu is really not such a good idea. Firstly, your HR will be elevated, and you'll probably also not be able to breathe properly thereby not getting enough oxygen into the blood. The additional strain could cause tears in the muscle (heart) and apparently these scars never go away. End result, potential permanent heart damage.<br /><br />This was confirmed by a sports scientist during one of our club talks and I'm not willing to gamble with my heart.
