CHAPTER 2: SAFETY AND INJURY PREVENTION
GENERAL ENVIRONMENTAL
CONDITIONS
• Heat Stroke Story
• Acclimatization-is the process of allowing your body
to adapt slowly to weather conditions.
• Rehydrate-restore lost fluid before, during and after
exercise.
• Before- 1 ½ - 2 ½ cups 10 to 20 min. before
• During- 1 ½ - 3 ½ cups per hour
• After- 2 cups for every pound lost
EXTREME HEAT AND FLUID BALANCE
• Heat Cramps- a muscle spasm resulting from the
loss of large amounts of salt and water through
perspiration.
• Heat Exhaustion- overheating of the body resulting
in cold, clammy skin and symptoms of shock.
• Heat Stroke- most severe: a condition in which the
body can no longer rid itself of heat through
perspiration.
HEAT CONDITIONS
• Heat-Stress Index- measurement of the combines
effects of heat and humidity on the body.
• Wet bulb- Measures the temperature one feels
when one's skin is wet and is exposed to moving air.
• How should you dress for the heat?
EXTREME COLD CONDITIONS
• Hypothermia- a condition in which your body
temperature drops below normal
• Frostbite- tissue damage from freezing temperatures
• Wind-Chill Factor- The combined influence of wind
and temperature on the body
• How should you dress for extreme cold?
OTHER ENVIRONMENTAL CONCERNS
• Pollution Effects on the body
• Altitude- less oxygen available at high altitudes and
can reduce your ability to perform strenuous
exercise.
• Personal Safety
• Vests
• Helmets
• Unleashed Dogs- The Coach (Faber) Barnette Story
OTHER SAFETY PRECAUTIONS
• Choosing correct footwear
• Activity
• Time of day to purchase
• Importance of correct form
• Warm up/Cool down
SKIN INJURIES
•
•
•
•
Abrasions
Chaffing
Calluses
Blisters
OTHER COMMON INJURIES
• Sprain- (joint) a stretch of the ligament
• Strain- Injury to a muscle or tendon: either a stretch
or a tear
• Contusion- a bruise caused by a blow to your
muscle, tendon, or ligament
PREVENTION
• Fatigue and pain are usually a signal that you are
pressing too hard. Be sure to stretch thoroughly
before your work-out, and stop before you are
exhausted.
• Stress injuries can also result from poor muscle
balance, lack of flexibility, or weakness in soft tissues
caused by previous injuries.
