The “Game Plan”
1. Recognize different types of
injury prevention equipment
2. Understand the evolution of
the helmet and its purpose
3. Update on the benefits and
types of mouth guards and
ocular protection
4. Recommend evidence-
based protective equipment

Standards for Athletic Equipment
(NOCSAE) established in 1969
• Goal was to initiate research efforts for
head protection
• First football helmet safety standard
established in 1973
• 16 member board

NOCSAE Standard
• Helmets placed on a
polyurethane head form
• Dropped from a height of
60 inches
• 6 different impact sites
tested
• Forces transmitted to the
head cannot exceed 1200
force units

The Success of NOCSAE
• >100 high school and college
football players in the 60’s killed
due to skull fractures and acute
bleeding
• After NOCSAE standard, skull
fractures have mostly disappeared
and deaths each year ~3 to 4
