overwork, dehydrationStrain

Condition in which muscles have been overworked Can occur from participating in strenuous activity you

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

TREATMENT

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

death Concussions: temporary disturbance of the brain’s ability

to function

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
