injuries1
injuries
  • Most common injuries that occur from exercise are to the muscular and skeletal systems.
  • Usually result from too much stress on a joint or muscle
minor exercise related injuries
Minor exercise related injuries
  • Muscle Cramp
    • Spam or sudden tightening of the muscle
    • Usually resulted from irritation in muscle from tired, overwork, dehydration
  • Strain
    • Condition in which muscles have been overworked
    • Can occur from participating in strenuous activity you are not used to
  • Sprain
    • Injury to tissues surrounding joint
    • Ligaments may be stretched or torn
    • Accompanied by sever pain, swelling, difficulty moving
treatment
Treatment
  • RICE
    • Rest
      • Avoid using affected area for 1-2 day
    • Ice
      • 20 min on, 20 min off
    • Compression
      • LIGHT pressure can help reduce swelling
    • Elevation
      • Raise affected limb above heart level can reduce pain and swelling
major injuries
Major Injuries
  • Fractures
    • Any type of break in a bone
    • Usually require immobilization
  • Dislocation
    • Bone slips from its normal position at a joint
    • Bone put back in place, immobilization so tissue can heal
  • Tendinitis
    • Tendons stretched or torn from overuse
    • Rest, medication, physical therapy to heal
  • Blows to head
    • Can cause swelling of brain; unconsciousness and even death
    • Concussions: temporary disturbance of the brain’s ability to function
hot weather risks
Hot Weather risks
  • Most are related to overexertion, overworking the body, or dehydration
  • Heat cramps: muscle spasms that result from 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
    • Happens in hot, humid atmospheres
  • If you continue exercising with these conditions, can result in heat stroke
cold weather risks
Cold Weather Risks
  • Frostbite: condition that results when body tissue becomes frozen
    • Typically affects head, face, feet, and fingers
  • Hypothermia: condition in which body temperature becomes dangerously low
    • Brain can’t function, body systems shut down
