Document Summary
Used to be called acute or chronic. At some point if injuries don"t heal they are termed chronic. What if they came on slowly and resulted in only mild disturbances in activity: chronic injuries = don"t always know they are injured until the pain starts. Traumatic (acute: occurs suddenly and has a clearly defined cause or onset, occurs when tissue loading is sufficient to cause sudden irreversible deformation of the tissue, usually in high speed sports with or without high energy contact. Extrinsic/external originating outside the anatomical limits of a part: bad shoes, increased duration of training, not enough rest, icy field conditions etc. Intrinsic/internal belonging to or lying within a given part: tight hamstrings, flat feet-pes planus, knee malalignment etc. Contractile tissue with central function to generate power. A well vascularized muscle : good o2 & nutrients, good for healing, bleed lots, bruise internal, laceration external. Muscle contraction in which length of muscle stays constant.
