https://community.usms.org/swimming/f/general/5464/overexertion-is-it-possible-to-do-damage-to-your-lungsOverexertion: pushing it to the point where the body is wracked with waves of nausea and you are left gasping for breath. Or overpushing it when you are doing SDK&#39;s to the point of nearly passing out and your lungs feel like they are going to burst.

A heart attack, on the other hand, is a possibility (a topic which has been discussed on this forum previously). There is a definite risk associated with strenuous (as compared to moderate) exercise, obviously greater in those individuals with heart disease (diagnosed or not).<div style="clear:both;"></div>https://community.usms.org/thread/71639?ContentTypeID=1Sat, 28 Jul 2007 14:21:21 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:1855c184-c523-4dc5-8697-472aa8cbdbd9Former MemberI had a couple of Canadian international coaches who tried to push swimmers to the point you talk about. They said I was lazy, I gave them the four letter word reply and a hand signal.<div style="clear:both;"></div>https://community.usms.org/thread/71562?ContentTypeID=1Sat, 28 Jul 2007 11:39:39 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:0aca2d91-2c8e-49a0-9409-bb81480f55d7Former MemberI don&#39;t think your lungs are the issue - what is your pulse when all of this is happending?<div style="clear:both;"></div>https://community.usms.org/thread/71800?ContentTypeID=1Sat, 28 Jul 2007 01:48:35 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:20588a05-472c-4b7d-8243-b0a4e265c580knelsonThe nausea thing is interesting. There was another thread about puking during workout and it sounds like this isn&#39;t all that uncommon. I don&#39;t ever recall in my life felling nauseous from overexertion. I guess this must be something that varies depending on the individual. Some people must be more prone to nausea. I can only recall throwing up once in my adult life and that was due to a serious medical condition that required surgery. Anyway, just thought it was strange how different people react to pushing their bodies to the limit.<div style="clear:both;"></div>
