i never said holding breath could be harmful, but i do think there is definitely a line... for example, i know for a fact that clinical tests have shown on billions of people throughout history that going without oxygen for too long causes permanent death, just as jumping off tall things also kills people... how tall can you make the thing before dying? before breaking bones? is it even a good idea to push the boundaries in this way, if dropping off a 2m block is all you need for plyometric training?

i think that freediving training could be good for hockey because it helps train efficiency for the lungs, blood etc etc. in fact i've done a bit of reading where i have been able and have found a couple of interesting exercises which i've tried, none of which i've particularly found useful for hockey but which obviously could be useful for someone. all good.

HOWEVER my personal opinion which i am perfectly within my rights to express is that there is a line to draw, and i think you agree.

i personally think that line is drawn just before anything to do with contractions. i think the body can be stressed perfectly well enough without the need for that. but... what the heck is a contraction anyway? not everyone gets them...? are they different for everybody?

so... i'm all for education, and i'll admit i don't know a lot about it. could you then explain exactly what happens when someone gets a contraction?




(i've met the guy i referred to and he is not slow, but his friends agree that his sport has made him that way... his friends are freedivers and most of them very good ones. i know a lot of odd people so he didn't seem odd to me)
