I can just feel them working against me. But I'd rather be slow than freeze my nuts off (literally)
I remember reading [in an actual book] that the ideal temperature for heavy physical exertion is 6C. It didn't differentiate between aerobic vs. anaerobic, but the idea was that it was cool enough so that you didn't get too hot. Also, the test subjects just wore t-shirts and shorts, no jackets. I would imagine that the greater the exertion, the colder it can be [to a point].
