Types of Muscle Contractions

Isometric = Constant velocity movement around a joint Isotonic = Tension remains the same whilst the muscles length changes Concentric = Muscle contraction occurs when a force applied to the muscle exceeds the momentary force produced by the muscle itself Eccentric = There is no change in the length of the muscle

Concentric = Wall - sits Isometric = Rise of a sit up Eccentric = A bi-cep curl Isotonic = Lowering of a bi-cep curl

Isometric = Tension remains the same whilst the muscles length changes Isotonic = There is no change in the length of the muscle Concentric = Causes tension on a muscle as it shortens Eccentric = Constant velocity movement around a joint

<p>Concentric = No change in muscle length Isometric = Forced lengthening of the muscle-tendon system Isotonic = Muscle length increases Eccentric = Muscle length decreases</p> Signup and view all the answers
