Document Summary
Why would force be a risk factor for injury. Depicted by a force / time graph. When tissue load exceeds tolerance threshold it is injury. Bone is a little bit di erent because it s subject to di erent loads. Bone strength is dependent on direction of loading and type of loading. Tension is pulling forces from opposite ends of the bone. Shear force is a horizontal force acting in oppose directing. Why would posture be a risk factor for injury: Optimal length is the most actin and myosin cross. The longer the length of the muscle is from the axis of rotation the greater your moment will be. The larger the moment the greater potential for injury. When two curved meet there is a rise of injury. Why would reparative be a risk factor for injury; Arbitrary because not everyone knows what their capacity is. What can we do with this information.
