As an athletic trainer, you are supervising the rehabilitation of a junior baseball pitcher who underwent minor shoulder surgery during the winter. His rehabilitation is progressing well and is now able to do all the exercises you prescribe. You are considering adding some functional exercises to his program. Fully explain what is meant by functional exercises and then be creative and suggest five functional exercises to stress his shoulder. Then explain why each exercise would be considered a functional exercise.

- How much force must be produced by the biceps brachii, attaching at 90? to the radius at 3 cm from the center of rotation at the elbow joint, to support a weight of 200 N held in the hand at a distance of 30 cm from the elbow joint? (Neglect the weight of the forearm and hand, and neglect any action of other muscles)arrow_forwardAn 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_forwardDiscuss the biomechanical factors that influence the ability of the thigh, leg, and foot to rotate about the hip joint during a sprinting stride.

- A) Describe the difference between strength and power during a squat. Provide a quantitative example that illustrates the difference. B) During a squat, the weight you have on your shoulders has a certain amount of gravitational potential energy. As you squat down and come to a stop at the bottom of the squat, some of that energy is lost. Where does it go?arrow_forwardThe data was collected at 100 frames/second. Calculate the velocity and acceleration for each of the joints for the X(horizontal)coordinate. Also, graph the displacement of all three joints (ankle, knee and hip) for the Y (vertical) coordinatearrow_forwardIf an individual does training with only the right knee extensor muscles, it is common to see increase in strength in knee extension force for the right leg and an increase in strength in the knee extension force of the left leg (although the increase in force is typically not to the same extent as the force increase in the right leg) a.)
