Document Summary

Used to be called acute or chronic. Confusing because all injuries are technically acute something initiate them. At some point if injuries don"t heal they are termed chronic. Occur when tissue loading is sufficient to cause sudden irreversible deformation of the tissue. Usually in ______ speed sports with or without high energy contact. Repeated overloading, each incidence of which, alone is not enough to cause irreversible deformation, but which when accumulated over time exceeds the tissue threshold. Seen in aerobic sports that require lengthy training schedules or in technical sports where a movement is repeated numerous times. _______ - originating outside the anatomical limits of a part. _______ - belonging to or lying within a given part. Contractile tissue with central function to generate power. Isometric- muscle contraction in which lengthen muscle stays constant (moderate force) Concentric - muscle shortens while contracting against resistance (reduced force with increased speed)
