Study Notes

Causes of Sports Injuries

  • Occur when an object encounters TRAUMA or PHYSICAL FORCE that is greater than what it can resist or absorb.

Direction of Forces Applied to Musculoskeletal Structures

  • Tensile forces act away from the center of the structure, causing a pull or stretch.
  • Compressive forces impact the center causing it to bend or fold.
  • Shear forces are opposing forces toward the different ends of the structure causing it to twist.

Structure Function

STRUCTURE FUNCTION
LIGAMENTS Stabilize joints
TENDONS Attaches muscles to bones
MUSCLES Creates movements
BONES Anchor for muscles
JOINTS Fulcrum for movement

Sports Injuries

  • ACUTE INJURIES - have signs and symptoms that manifest immediately after force application.
  • CHRONIC/OVERUSE INJURIES - signs and symptoms occur after a long period of exposure to the force.

Acute Injuries

  • SPRAIN
    • overstretched ligament.
    • Ligaments stabilize and limit joint mobility.
    • Common sprains: lower limbs & ANTERIOR CRUCIATE LIGAMENT (ACL)
    • An individual usually feels a popping sound when a knee ligament is completely torn.
    • A sprained joint will take several days or months to heal, depending on the severity.
    • ACL - a connective tissue that helps stabilize the knee every time the muscles contract.
  • STRAIN
  • FRACTURE
  • DISLOCATION
