I was reading here:
I remember well that I was educated as well in high school, to not do neck circles. My sports teacher told me "neck circles backwards (i.e. into the neck) are no longer to be used".
In latin america? everyone is doing neck circles during warm up. When I mention it's bad practice they go like "LOL we all have to die anyway" and keep doing it.
I tried to look up spanish articles about it, found nothing. I found some german and english articles like the one above, but nothing scientific. Is there scientific evidence?
the german article, actually stated that 2 people died in the 80s source (is german): http://sport-attack.net/ueber-kopfkreisen-und-schulterkreisen-vorwaerts-ungesunde-uebungen/?print=pdf
I translate the bit where they mention people died:
If the blood supply is interrupted here, may cause dizziness or, in extreme cases, cycloidal collapse. Especially in the In the 80s, there were even two deaths in competitive sports that made the headlines, causing many exercise dictionaries were rewritten.
so, where is that scientific proof? like a solid article.
Or is it all a myth, and that's why there is no proof? "Go neck circles go!" ?
