ORIGINAL: goodpuddles puddles knows.. this is just a posting on the internet and lots of information to consume.. but how safe is choking? puddles understands there are risks associated, and that it's a bit of edge play, but exactly how dangerous is this activity? Apparently it can be done fairly safely by some people.... while others seem to cause a lot more harm playing with it...might want to consider why. http://www.judoinfo.com/chokes2.htm http://www.judoinfo.com/chokes3.htm http://www.judoinfo.com/chokes5.htm http://www.judoinfo.com/chokes4.htm quote:
Spectral analysis of electroencephalography changes after choking in judo (juji-jime). Author: Rau R , Raschka C , Brunner K , Banzer W Source: Med Science Sports Exercise, 30(9): 1356-62 1998 Abstract: PURPOSE: The present study was carried out to investigate possible electroencephalographic changes induced by choking in judo (shime-waza) by means of spectral analysis and brain mapping. METHODS: Power spectral changes in Electroencephalography (EEG) were recorded in six experienced judoka who underwent a choking trial with a "shime-waza choking" technique called juji-jime. RESULTS: A significant increase of global field power in the delta- and theta-range occurred, while physiological alpha-power decreased. These changes in the low-frequency range reached a statistically significant level within a time span up to 20 s after choking, which was performed at an average choking time of 8 s. In no case did choking provoke neuropsychological symptoms. Yet, spectral EEG-analysis revealed subclinical changes of brain function. CONCLUSIONS: Choking in judo may induce subclinical electroencephalographic perturbations. The extent and duration can be objectified by means of spectral analysis of EEG data, global field power computation, and brain-mapping representation. http://www.bath.ac.uk/sports/judoresearch/articles/indexa.html
