During an isometric contraction, the length of the muscle DOES NOT change. During an isotonic contraction, the length of the muscle DOES change (shorten). To demonstrate an isometric contraction, place the palm of your hand underneath the desk/table top. Push up and with your other hand, cup the palm over the anterior surface of the pushing arm. What did you notice about the \"tone\"/firmness of the muscle? Did your forearm or hand move as you pushed up on the desk/table? Therefore, did the muscle shorten or stay the same length? To demonstrate an isotonic contraction, start with your left forearm resting on top of the desk/table. Place a pencil in your hand and grasp it. Complete a bicep curl with the pencil and cup the palm of the other hand over the anterior surface of the lifting arm. What did you notice about the \"tone\"/firmness of the muscle? Did your forearm or hand move as you bet your elbow on the desk/table? Therefore, did the muscle shorten or stay the same length?
