KINESIOLOGY

• Kinesiology - study of movement
• Kinematics - types of motions w/o regards to the forces acting on the body
• Kinetics- focuses on the forces acting on the body
• 3 dimensional planes

  • Saggital plane
  • frontal Plane
  • Transverse plane
• SHAFT

  • Standing erect
  • Head facing forward
  • Arms at the side c palms facing forward
  • Feet slightly afar
  • toes facing forward
• Fundamental position- palm facing the body
• Fundamental Position- use to initiate motion
• X axis - horizontal axis

  • sagittal plane
  • actions- flexion & Extension
  • y-z plane
  • Mediolateral
  • frontal axis
  • DF & PF
  • axis/ coronal
• Y axis- superinferior axis

  • vertical axis
  • transverse plane
  • x-z plane
  • action- rotation
• Z- Anteroposterior axis

  • Frontal plane/ coronal plane
  • x-y plane
  • ABD/ ADD
  • Lateral flexion
  • RD/ UD
• 1st Carpometacarpal jt- 1st metacarpal and trapezium - rotated 90 degree
• Abd/ Add

  • axis - x
  • Plane - saggital
  • palm of the hand - perpendicular
• Flex/ Ext

  • Axis- Z
  • Plane- frontal/ coronal
  • Palm of the hand Parallel
• 2 types of displacements

  1. translatory/ linear motion - all points of the moving object travel at the same time, velocity, and distance
  2. Rotatory/ angular motion- Each point of the moving object travel at diff time, velocity and distance
• 2 subtypes of Kinematics

  1. Osteokinematics- focuses on the movement of bony segments
  2. arthrokinematics- focuses on the minute movement of the jts
• 3 types of arthrokinematics

  1. Rolling- Rotatory or Angular motion
  2. gliding/ sliding- linear or translatory motion
  3. spinning- one point remain in contact w the same point
• Kinematic chain is a combination of Scaral Jt uniting successive segments.
• In OKC, the moving segment is distal and the fixed segment is proximal.
• In CKC, the moving segment is proximal and the fixed segment is distal.
• In OKC, the function is skill/tul and in CKC, the function is stability and fast mounts.
• In OKC, the relation between the segments is independent and in CKC, the relation between the segments is dependent.
• In OKC, the OPP is 1005e packed position and in CKC, the OPP is incongruent.
• In OKC, the ligaments are lax and in CKC, the ligaments are tight.
• In OKC, the axes are aligned and in CKC, the axes are offset.
• Law of accelaration - Inversely proportional to mass - directly proportiarnal to force 3
• Law of Action - Reaction (interaction) - for every action, there is an opposite equal reaction
• Gravity - most prevalent - gravitational force = weight
• F = MA (9.8 m/S°)
• Center of Gravitg/ Center of Mass - theoretica point: contentration of mass is located
• Center of Gravity location
• Slightly ant
• 52 - falls near the A 515 - 55% of the person's height
• 52 pwede narin falls near the ASIS mo
• Apir Tayo! COG ng braso Ko, medial triceps ko ito, PT (Pronator Teres), Bid MCP sa hand
• Apir Tayo! COG ng hita Ko, adductor brevis ko ito Poplitous, Ind MIT sa foot
• Line of Gravity is a gravitational vector pointing downward, represented by a plumbline.
• Through, Anterior, Posterior are directions relative to the spine.
• Externally applied force is a type of force that is applied from the outside.
• Friction refers to forces that resist motion.
• A is the cervical vertebrae, B is the thoracic vertebrae, C is the lumbar vertebrae, D is the pelvic vertebrae, E is the sacrum, F is the coccyx.
