Icy water claim

This claim has been added without support, and my consequent removal has been reverted by User:Heaviside_glow. I have searched google scholar, and found no explicit confirmation of this phenomenon, and I doubt that q10 is the dominant factor (as opposed to more typical causes of hypothermic death). However, I may be wrong on this. Please provide links to peer-reviewed scientific articles supporting this claim. HCA (talk) 02:31, 24 March 2016 (UTC)

• Take a look at this article. I will adjust my sentence. Heaviside glow (talk) 19:16, 25 March 2016 (UTC)

This article does not actually substantiate your claims. Did you read it? Q10 is discussed only in the context of the brain and the cooling rate thereof, not in terms of drowning. There is some mention of cooling of the hands, thereby preventing gripping objects, but that's hardly the same as the claim that Q10 impairs the overall swimming ability before other effects become problematic.

"This cooling has a direct deleterious effect on neuromuscular activity. This effect is especially significant in the hands, where blood circulation is negligible, leading to finger stiffness, poor coordination of gross and fine motor activity, and loss of power. It has been shown that this effect is primarily due to peripheral and not central cooling. The loss of motor control makes it difficult, if not impossible, to execute survival procedures such as grasping a rescue line or hoist, etc. Thus the ultimate cause of death is drowning, either through a failure to initiate or maintain survival performance (i.e., keeping afloat, swimming, grasping onto a liferaft, etc.) or excessive inhalation of water under turbulent conditions."

Yeah, I read that part. Except the hands don't actually contain any muscles, making it an indirect link at best. However, upon following the references, I found this (http://www.ncbi.nlm.nih.gov/pubmed/8526834) showing that biceps temperature drops enough for q10 to be an issue there, too. That said, I think it shouldn't be in its current location, but rather moved to the end, and there are better examples from ectotherms to illustrate q10. In future, can you please include the reference with the initial edit? HCA (talk) 14:28, 29 March 2016 (UTC)
