Study Notes
Exercise Safety and First Aid
- This unit covers exercise safety and first aid, focusing on safety practices in sports and exercise.
- It aims to differentiate between acute and chronic injuries.
- It describes common forces during injury mechanisms.
- It explains the inflammatory response's role in healing.
Causes of Common Sports Injuries
- Injuries occur when tissues or organs encounter trauma or physical force greater than their capacity to resist or absorb.
- Acute injuries are sudden and severe, occurring during physical activity.
- Chronic injuries develop over time due to repetitive stress or misuse.
Common Forces During Injury Mechanism
- Tensile forces: These forces act away from the center of a structure, causing a pull or stretch.
- Compressive forces: These forces act on the center of a structure, causing it to bend or fold.
- Shear forces: These forces act on opposing sides of a structure, causing it to twist.
Musculoskeletal Structures and Injuries
- Ligaments: Stabilize joints; a sprain is the injury.
- Tendons: Attach muscles to bones; a strain is the injury.
- Muscles: Create movements; a strain is the injury.
- Bones: Anchor muscles; a fracture is the injury.
- Joints: Fulcrum for movement; a dislocation is the injury.
Sprains and Strains – Severity
- Sprains: Damage and stretching to ligaments surrounding a joint.
- Mild: Minimal tear, pain when moved.
- Moderate: Partial tear, pain at rest and when moved or activated.
- Severe: Complete tear, full loss of function.
- Strains: Pulling or tearing of muscle or tendon.
Acute Injuries
- Sprain: Overstretched ligament from forced joint movement.
- Strain: Twist, pull or tear of muscle or tendon (non-contact or from overstretching).
- Fracture: Bone break, from high impact/stress.
- Dislocation: Separation of bones, from movement beyond normal range.
- Concussion: Life-threatening brain injury from bumps or hits to the body.
Chronic Injuries
- Stress Fracture: Tiny cracks in a bone from repetitive force (overuse).
- Tendinopathy/Tendinitis: Muscle-tendon injury from muscular imbalance.
- Osteoarthritis: Wear and tear of a joint, diminishing cartilage protection.
- Bursitis: Inflammation of the bursa, irritating surrounding structures from repetitive stress.
Causes Of Heat Related Illnesses
- Heat illnesses result from excessive dehydration and high body temperature, often from poor training conditions.
- Extreme heat hinders the body's cooling mechanism through sweat evaporation.
- This can increase core body temperature past safe limits, leading to heatstroke or other severe health issues.
Signs of Dehydration
- Dizziness
- Fatigue
- Weakness
- Dry mouth
- Flushed skin
- Headache
- Blurred vision
- Difficulty swallowing
- Dry skin
- Hot skin
- Rapid pulse
- Frequent need to urinate
Injury Prevention Strategies
- Implement comprehensive training programs.
- Use protective equipment and practice correct techniques.
- Incorporate recovery strategies into training regimens.
- Follow rules and maintain good sports decorum during competition.
