The assumption that humans injure their muscles if not properly warmed up is not correct. There is no scientifically supported evidence that humans have to "warm-up" or stretch prior to exercise to avoid muscle strains. Ian Shier's work out of Britain shows not association between the two and some work out of Australia shows a negative association between pre-game stretching and injury risk. Thus there is likely no requirement for animals to warm up. Some recent references and abstracts are: J.D. Blank and E.D. Stevens. J Muscle Res Cell Motil. 2001;22(4):301-10. Passive stretching does not protect against acute contraction-induced injury in EDL muscle G. Gremion. Rev Med Suisse. 2005 Jul 27;1(28):1830-4. Is stretching for sports performance still useful?
