• what's the title of the lesson 1

  sports injury
• are damaged tissues or organs which occur when it encounters trauma or physical force that is greater than what it can resist or absorb.

  Injuries
• direction of forces applied to musculoskeletal structures

  Compressive, Tensile, Shear
• compressing the muscle, and one of the example is when ''nadagan ng puno''

  Compressive
• over stretch

  tensile
• the muscle moves in another direction. (force)

  shear
• two types of injuries

  chronic/overuse, acute injuries
• sign and symptoms occur after a long period of exposure to the force

  chronic/overuse
• have signs and symptoms (E.G., Pain, Treatment) that manifest immediately after force application.

  acute injuries
• three types of overuse injuries according to severity

  stage 1-stage3
• complain of pain only after the activity, game, or training session

  stage 1
• Complain during and after an activity but do not feel it during test

  stage 2
• the athlete feels pain whether at rest or play

  stage 3
• it stabilizes joints (bone to bone)

  ligaments
• attaches muscles to bones

  tendons
• ligaments and tendons similarity

  both are connective tissue
• creates movements

  muscles
• anchor for muscles

  bones
• fulcrum for movement

  joints
• the chart that can show the structure and their function

  musculoskeletal structures
• common sports injuries (acute injuries)

  sprain, strain, fracture, dislocation, wounds,concussion
• injuries from the soft tissues affecting the ligaments and blood vessels which are stretched and occasionally torn or partially torn.


  sprain
• injuries to muscles or tendons from over exertion affecting the fibers which are stretched and sometimes partially torn.


  strain
• sprain - ligaments
• strains - tendons
• in sprain there's 3 grade
• what grade on sprain when the ligament is not tear but aching

  grade 1
• what grade on sprain when the ligament is a little bit torn

  grade 2
• grade of sprain if the ligament is entirely torn apart from each other.

  grade 3
• what type of classification of sprain and strains according to severity it is when you feel pain when moved, have a minimal tear and is in 1st degree.

  mild
• it is when you can feel the pain at rest and when moved, it has also had a partial tear and is the second degree

  moderate
• it is when you completely loss of function, it has a complete tear and is in the third degree

  severe
• difference between fracture and dislocation

  fracture is when the bone breaks apart, while the bone in dislocation just got misplaced
• breaking of a part, especially a bone. break in the continuity of bone. may caused by trauma, twisting due to muscle spasms, or indirect loss of leverage or by disease.

  fracture
• causes of fracture

  1. by direct blow
  2. by crushing force
  3. by fall or automobile accident
• types of fracture

  1. transverse
  2. linear
  3. oblique nondisplaced
  4. oblique displaced
  5. spiral
  6. greenstick
  7. comminuted
• crack is horizontal

  transverse
• the crack is vertical

  linear
• the bone crack is middle horizontally but does not break into each other

  oblique nondisplaced
• the bone crack is middle horizontally but it is entirely break into each other

  oblique displaced
