Yep.

Quoted message said:have come to the conclusion that I may be suffering from this ailment. I have yet to seek medical
help on it, but am near that point. Before I do, I was wanting to check my symptoms. I feel it in
a sprint or a climb. It is as if I can't get air into my lungs fast enough. I have had this
problem for several years and always though I needed to train more. Lately I have hit a wall, no
matter how much more I train it continues to plague me.
This could still be caused by exertion. Everybody has their limits, which will be most felt on a
sprint or climb. It could well be that you've reached your peak. Even when I've not got asthma, I
still get the feeling of being heavily out of breath, but there's a big difference between maximum
lung capacity and EIA.
EIA is a completely different feeling that comes in a range of severities. Asthma is caused by
irritation to the bronchi and in the case of EIA, the stimuli is the bronchi trying to open too
quickly to accomodate increased intake of air. In this case the bronchial walls spasm and expand
causing a narrowing of the airways.
Rather than the feeling that you can not get the air in fast enough, it feels more like you have a
huge weight on your chest which is only allowing a little bit of air to enter your lungs. In the
worst cases, it feels like you're being suffocated.
Even when you stop and rest, recovery (even with medication) can take 30 minutes or more before you
feel you can breathe normally. It will also, in the recovery stages and sometimes after exercise,
manifest itself as wheezing.

Quoted message said:mentioned it to my doctor once before but he knows the guys I ride with and said we ride too fast
(jokingly). I only recently found out about exercise induced asthma and it seems to match.
There are a couple of things that IME will trigger more severe attacks. Going from zero activity to
high intensity within a very short period of time causes big problems. When I jump on the bike, I
have to force myself to start really slowly, and gradually pick up the pace allowing my lungs to
adjust as I increase the intensity. Avoiding steep climbs and sprints for the first 20 minutes or so
allows the lungs to aclimatise.
Cold weather makes things worse. The cold air against the warm bronchi is a bad stimulus which
causes them to spasm more. Warming up properly in these conditions is even more important.
I'm gradually trying to wean myself off the medication, by understanding better how my body works,
but at times there's no avoiding it. Certainly, if your doctor diagnoses you, initially it's a good
idea to take the med preventatively 20-30 minutes before you start exercising.
