The flashcards below were created by user JJLT on FreezingBlue Flashcards. What would you like to do?


  1. A reversible condition in which a muscle is no longer able to generate or sustain the expected power output
    Fatigue
  2. The amount of extra oxygen required by muscle tissue to oxidize lactic acid and replenish depleted ATP and creatine phosphate following vigorous exercise
    Oxygen debt
  3. A molecule whose high energy phosphate bonds are created from creatine and ATP when muscles are at rest
    Creatine phosphate
  4. After death, muscles are unable to bind more ATP because metabolism stops and ATP supplies are exhausted; muscles freeze due to immovable cross bridges and tight binding of myosin and actin for a day or so until enzymes in decaying fiber begin to break down muscle protein
    Rigor mortis
  5. The strength of an isometric contraction to the length of the muscle at which the contraction occurs
    Length tension curve
  6. Any contraction that creates force and moves a load
    Isotonic contraction
  7. A muscle contraction in which the muscles shorten while generating force
    Concentric contraction
  8. The muscle elongates while under tension due to an opposing force greater than the muscle generates
    Eccentric contraction
  9. Contractions that create force without moving a load
    Isometric contraction
