I just saw some arm compression sleeves and was reading about the increase of blood flow, temp increase and wondered if anyone had ever used them (in the winter or cold times) and noticed a difference?
if your thinking in terms of support then they can be useful in the short term...ie supporting a weak joint.
In terms of blood flow - if you're compressing then i would think that arterial resistance goes up and thus less blood delivered. If your trying to increase venous return then compression helps but a elastic band isnt going to add much your muscles can't do during exercise for upper body.
When its cold it helps insulate but so does a shirt.
The sleeves used on patients feet during long surgeries are to prevent deep vein thrombosis since the muscular-venous pump isnt in action.
This comment is clearly racist and does not contribute to the original query. It is offensive and insensitive and contributes to the fair assumption that outdoor education lags behind when it comes to diversity.
Plus, it's only a guideline, like the speed limit, and you're clearly in violation of it for being racist in assuming only black people play basketball. I personally take offense to that because I have a pretty mean lay-up.
