Which of the following best describes an isometric contraction?*1 pointA contraction where the joint angle and muscle length do not change.Performing a movement without going through complete range of motion.Repeating the same movement over and over until you are unable to do any more.The act of gradually adding to the amount of resistance that you use in a movement.

During isometric contraction, muscles do not change length. Group of answer choicesTrueFalse

isometric contraction, skeletal muscle stays the same length as it contracts.

Which of the following statements concerning types of muscle contractions is false?Multiple ChoiceIn isometric contractions, the amount of tension produced by the muscle is constant.The contractile processes in isometric and isotonic contractions are the same.Most skeletal muscle contractions are a combination of isometric and isotonic contractions.In isotonic contractions, the amount of tension produced by the muscle fibers is constant during the contraction.In isotonic contractions, the muscle fibers shorten.

An isotonic contraction in which tension in the muscle increases enough to overcome the opposing resistance, while the muscle shortens is a(n) Blank______ contraction.Multiple choice question.eccentricconcentricisometricclonic
