- An isometric exercise is one in which the joint angle does not change during the application of muscle force. For instance, you can join your hands together, pushing down with one hand and pushing up with the other. In each arm, the muscles that provide the force are connected to the bones of the arm by tendons. If you increase the forces but keep the angles the same, the muscles will still contract. Explain how this is possible.arrow_forwardThe biggest force of contraction can be produced by: Select one: a. SO fibers b. FOG fibers c. FG fibers d. All types of fibers produce the same force of contractionarrow_forwardWhich of the following is true? A. Muscle fibers either will contract with all the force possible under existing conditions or will not contract at all. B.
