Avoiding Injuries Objectives. Describe the most common injuries that occur during exercise. Identify weather-related risks when exercising. Explain ways to avoid risk and injury during exercise
How many of you have ever had a Muscle cramp????
Minor Exercise Injuries Cramp- a spasm or sudden tightening of a muscle Strain- Is a condition in which muscles have been overworked Sprain- is an injury to tissues surrounding a joint
Treatment of Injuries R.I.C.E. REST ICE COMPRESSION ELEVATION
Major Injuries How many of you have ever fractured a bone? Fracture- any type of break in a bone Any one ever had a dislocation? Dislocation- results when a bone slips from its normal position at a joint. Tendinitis- a condition in which the tendons, bands of fiber connect muscles to bones, and or stretched or torn from over use.
Hot-Weather Risks Overexertion- over working the body Heat cramps- muscle spasm that are the result of the loss of large amounts of salt and water through perspiration. Heat Exhaustion- is an overheating of the body resulting in the cold, clammy skin and symptoms of shock. Heat Stroke- Continuing to overlook heat exhaustion SIGNS lead to this
Heat cramps Heat cramps are painful, brief muscle cramps that occur during exercise or work in a hot environment. Muscles may spasm or jerk involuntarily. Cramping may also be delayed and occur a few hours later. Heat cramps usually involve the muscles fatigued by heavy work such as the calves, thighs, abdominal muscles, and shoulders. A person is most at risk when: a person performs work or activities in a hot environment, usually during the first few days of an activity the person is not used to. a person sweats a great deal during exercise and doesn't rehydrate with water or fluid replacement drinks (such as Gatorade).
Heat Exhaustion Heat exhaustion occurs when your body gets too hot. The hypothalamus, the part of the brain that controls thirst and hunger, also controls the body's core temperature. Normally, the body cools itself by sweating. But if you are exposed to high temperatures for a long time (working outdoors in the summer, for example) and don't replace the fluids you lose, the body systems that regulate temperature become overwhelmed. As a result, your body produces more heat than it can release. Heat exhaustion requires immediate attention because it can progress to heat stroke, a life threatening illness.
Heat Stroke Heat stroke is a form of hyperthermia in which the body temperature is elevated dramatically. hyperthermia Heat stroke is a medical emergency and can be fatal if not promptly and properly treated. Cooling the victim is a critical step in the treatment of heat stroke. The most important measures to prevent heat strokes are to avoid becoming dehydrated and to avoid vigorous physical activities in hot and humid weather.
Frostbite Infants and elderly people are most susceptible. What constitutes extreme cold and its effect varies across different areas of the United States. Each year in the United States, nearly 10000 people suffer from frostbite.
