But why take professional research’s word for it, I’m sure your horse can tell you exactly how much he enjoys exercising in freezing temps.[/QUOTE]
Perhaps you need to review what peer-reviewed journal articles actually are. :lol: And actually read the articles in their full length and critically evaluate the work they have done. I have actually read Davis et al’s full articles- not just their abstracts. Their study has a serious flaw in it. They’re not using cold adapted horses. They’re using horses in Oklahoma, which is not cold at all.
Also, I fail to see how linking to websites to vets talking about the research papers I HAVE ACTUALLY read does anything to further your point. I told you I have read Davis et al’s research papers in full, so why post an abstract? :lol: So, 6 horses had an upregulation of IL-10 and few other cytokines… might not mean anything… might mean something… the researchers don’t know and state that more research is needed. A cytokine upregulation is not evidence of ‘serious damage.’ The research is weak at best. 2 or 3 papers published by the same group in warm Oklahoma. The study would have more credibility if they had used horses that were already in a -20C environment for months. And they used a air mask to chill the air and the level of air delivered was greater than what horses would normally inspire while exercising. “The
volume of air delivered (3,800 l/min) was in excess of the reported
maximal inspiratory rate for horses exercising at submaximal levels
(26) to prevent the horses from inhaling unchilled ambient air during
exercise.” Yes this was done help prevent inhalation of unchilled air, but this could potentially skew the results.
Also, I’m not sure why this is difficult for you to understand, but the research Davis et al did used -5C and 5C as the cold temperatures. (oh right you haven’t actually read the papers in their full length, although that info is in the abstract as well) So, really if we are to base the temperature when not to ride it would at or below 5C. So I guess you don’t ever ride under 5C? :lol: I’m really curious where you are getting the -15C as the cutoff point.
Also, I just have to point out the link to the Q&A vet actually stated this at the end “However, keeping your horse moving during winter in the North still has many benefits as long as it’s not “excessive.” Here then is my common sense advice for winter riding, which I think has value for the cardiopulmonary system, the musculoskeletal system, the digestive system and certainly the central nervous system (your horse’s brain!): gently and gradually warm up, take your time cooling down (including drying off if necessary), be aware of the footing if you’re riding outside so that your horse doesn’t slip, and respect your horse’s current fitness level.”
So this proves your point how??? hmmm seems to support my hypothesis better… :winkgrin:
Did you even actually read the second journal article you posted!!! :lol: (I can’t believe you posted this article in your defense- I kinda feel embarassed for you, but thanks for pointing this article out to me it’s very informative
) It’s conclusion states " In conclusion, cold exposure (-25C) did not seem to have any untoward effect on near maximal exercise tolerance. On the contrary, the cold weather seemed beneficial for heat disspation during exercise. Further no evidence of tissue damage in the respiratory tract was observed." And this research group actually took lung tissue biopsies, not just an RNA extraction of a lung lavage like Davis et al.
I think I’ve made my point… or rather you did for me. :lol:
Anyway, I’d love to keep arguing with you, but I’ve got a horse to ride.
