Document Summary

Athletic equipment: design to prevent injury to protect injured parts from further injury, proper fit sized to player, proper selection which is best for the player or for the sport. *should do all of them or else you wouldn"t use the equipment if it isn"t effective. 4 principles: (1) deflection (2) dissipation (3) deformation (4) absorption. Four principles: deflection a turning aside or off course, avoid direct contact (eg. helmet) Edges will deflect objects, hard equipment round and smooth, take as little force as you can. Disperse focal force over a large surface (the large shoulder pad will spread the force across it) There are 3 layers and various materials, first layer hard and round helps deflect, the padding beneath) Shoulder pads protect the ac joint, acromioclavicular joint, prevents dislocation. If they get a hard hit they will split their aca if there is no protection: deformation alteration of form or shape, made to change shape (eg. shoulder pads)
