Document Summary
Many factors are important in the prevention of athletic injuries: design, to prevent injury and protect injured parts from further injury, proper fit, proper selection. Practicality dictates that protective equipment should be: simple to fit and maintain, be durable and reliable, not be extremely expensive, minimal functional interference. Prevent protect: 4 principles of equipment equipment typically is designed under 2-3 of these principles. Which properties are important in deflecting force away from the body: round shape, hard & durable, and smooth, football helmet: smooth to prevent torque and injury (may prevent head injury but cause neck injury) Dissipation: to cause to spread thin or scatter and gradually vanish disperse focal force over a large surface area layers with various materials to help dissipate force. Deformation: alteration of form or shape change in shape or structure cantilever pad: designed to deform when hit and never actually touches the body part when compressed.
