Document Summary

Many factors are important in the prevention of athletic injuries. Design: to prevent injury, to protect injured parts from further injury. 4 principles: deflection, a turning aside or off course. Cantilever pad: may blow apart at high force. Bike helmet: absorption, to receive without recall orde echo, materials: Foam: open cell, close cell: air, fluid. Increased density = greater resistance at high force. Decreased density = more absorption at lower force: felt. Less tendency to shift or move over skin. Used to protect skin under hard edges of protective equipment. Decreased density = more absorption @ lower force. Used primarily for protection: ai(cid:396) (cid:272)a(cid:374)"t pass f(cid:396)o(cid:373) o(cid:374)e to a(cid:374)othe(cid:396) High resilience-material rebounds and returns to its original shape quickly: offers less cushioning at low levels of impact, not as comfortable close to the skin. Increased density = greater resistance @ high force. Mask 2-3 finger width from nose good vision. Strap snug to chin: 2 vs 4 point.
