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.
