Chapter 3 - Protective Equipment Flashcards
Which injuries are caused by high velocity, low mass collisions?
Focal injury
What causes focal injuries?
high velocity, low mass
Which injuries are caused by low velocity, high mass collisions?
diffuse injuries
What causes diffuse injuries?
low velocity, high mass
What are some features of low-density material
- soft, flexible, comfortable
- only effective at low levels of impact
- reduce friction (prevents blisters & abrasions)
What are some features of high-density material
- hard, ridgid, less comfortable
- better for high intensity impact (absorbs more force through deformation)
- protects from direct blows and focal injuries
What is another factor to consider in energy-absorbing material?
resiliance
- high resiliant (regain shape) = repeated impact
- low resiliant (deforms) = one time impacts
Name some types of soft protective materials
foam, nylon, moleskin, neoprene, gauze, felt, Sorbothane
Name some types of hard protective materials
moldable plastics (thermoplast, orthoplast), catsing materials (fiberglass, plaster),
What are some plastic materials?
Aquaplast Bluestripe, Multiform I & II, Orfit, Orthoplast II
What are some rubber materials?

must be 3mm thick lenses and be made from CR 39 plastic (or polycarbonate)
Which two organizations have standards for spectacles?
ASTM & CSA
T/F: You cannot wear contact lenses when swimming.
False, it’s allowed but not reccomended without goggles
T/F: Hard contact lenses result in more eye trauma (abrasions, cornea damage, dislogement bacteria trapped behind eye)
True
How long should swimmers wait to remove contacts after swimming and why?

distribute forces throughout the entire shoulder girdle
Which football position prefers the outside cantilever pad and why?
Lineman because it has a larger blocking surface and more shoulder protection
Which football position prefers the inside cantilever pad and why?
