Describe the differences between a PAR-Q, medical screening, medical evaluation, and exercise stress test.
These tests are listed in order of increasing rigor. The PAR-Q is a written assessment that predicts one's readiness for exercise. The other three require the help of a health professional to complete. Medical screenings and medical evaluations are both performed by a doctor, but the medical evaluation is more in-depth. Finally, the exercise stress test is designed to test the response of the body while exercising vigorously. This test is usually only used when a problem is suspected that could endanger the participant's life.
What is a concussion and what are the symptoms to look for?
A concussion is a mild traumatic brain injury caused by a blow, bump, or jolt to the head or body. Symptoms may include headache, dizziness, confusion, difficulty concentrating or remembering, nausea or vomiting, blurred vision, sensitivity to light or noise, unusual mood changes, drowsiness, or loss of consciousness. Anyone suspected of having a concussion should stop playing and be evaluated by a medical professional.
Describe the importance of using protective equipment when participating in sports or physical activity.
Protective equipment is designed to prevent the common injuries that can occur for each sport. While protective equipment does not completely eliminate the chance for injury, it does significantly reduce the risk.
Explain why the first step in responding to any sports injury is to remove the danger that led to the injury.
When someone sustains an injury while participating in sports, that indicates that something unexpected has occurred. There is a risk that the conditions that lead to the initial injury could continue to pose a health hazard both to the player who sustained the initial injury as well as other players; it is essential to remove that danger. Removing the danger could require stopping the sports activity or even transporting the injured person off the field of play. While it can be dangerous to move someone who has sustained an injury, it is more important to ensure the safety of the athlete by eliminating dangers that can result in severe injuries.
Explain how immobilizing an injured limb with a cast can enhance healing.
Immobilizing an injured limb enhances healing by preventing movements that can aggravate the injury and make it worse. This is the same reason why athletes should not continue to play a sport after suffering an injury: trying to push your body too far, too fast after suffering an injury can make it worse and prevent it from healing properly.
