    Biomechanics
  2. Position above a point of reference
    Superior
  3. Position below a point of reference
    Inferior
  4. Positioned nearest the center of the body, or point of reference
    Proximal
  5. Positioned farthest from the center of the body or point of reference
    Distal
  6. On the front of the body
    Anterior (ventral)
  7. On the back of the body
    Posterior (dorsal)
  8. Positioned near the middle of the body
    Medial
  9. Toward the outside of the body
    Lateral
  10. Positioned on the opposite side of the body.
    Ex: the right foot to the left had
    Contralateral
  11. Positioned on the same side of the body
    Ex: the right foot to the right hand
    Ipsilateral
  12. An imaginary bisector that divides the body into left and right halves
    Sagittal
  13. The bending of a joint causing the angle to the joint to decrease
    flexion
  14. The straightening of a joint causing the angle to the joint to increase
    Extension
  15. An imaginary bisector that divides the body into front and back halves
    Frontal Plane
  16. Movement of a body part away from the middle of the body
    Abduction
  17. Movement of a body part toward the middle of the body
    Adduction
  18. An imaginary bisector that divides the body into top and bottom halves
    Transverse plane
  19. Rotation of a joint toward the middle of the body
    Internal rotation
  20. Rotation of a joint away from the middle of the body
    External Rotation
  21. Movements in the sagittal plane include
    _________ and ______.
    Flexion, extension
  22. Movements in the frontal plane are ________ and ______.
    Adduction and abduction
  23. Movements in the transverse plane are _____ and ____ .
    internal and external rotation.
  24. Shoulder flexion
  25. shoulder extension
    • dorsiflexion
    • (pointing down = plantarflexion)
  26. abduction
  27. Moving in the same direction as the resistance
    Decelerates or reduces force
    lengthening of the muscle
    Eccentric
  28. No visible movement with or against resistance
    Dynamically stabilizes force
    Muscle maintains a certain length
    Isometric
  29. Moving in the opposite direction of force
    Accelerates or produces force
    Shortening of the muscle
    Concentric
  30. rhomboid muscle
  31. Sartorius muscle
  32. Anterior hip muscles
  33. An interaction between two entities or bodies that result in either the acceleration or deceleration of an object.
    Force
  34. The length at which a muscle can produce the greatest force. There is an optimal length at which the actin and myosin filaments in the sarcomere have the greatest degree of overlap results in the potential for maximal force production.
    Length-tension relationship
  35. The ability of muscles to produce force with increasing velocity. As the velocity of a concentric muscle contreaction increases its ability to produce force decreases. Conversely as the velocity of muscle actions increases with eccentric muscle action , the ability to develop force increases.
    Force-velocity curve
  36. The synergistic action of muscles to produce movement around a joint. All muscles working together for the production of proper movement are said to be working this.
    Force-couple
  37. To ensure that the kinetic chain moves in the right manner, it must exhibit proper _______ relationships. This can only happen if the muscles are at the right ___________ relationships and the joints have proper __________ (joint motion).
    • Force Couple
    • Length tension
    • arthrokinematics
  38. Movement of the bones and joints. The levers (bones) rotate arount the axis (joints).
    rotary motion
  39. Turning effect of the joint
    torque
  40. >Is concerned with those neural structures that are involved with motor behavior and how they produce movement.
    >The study of posture and movements and the involved structures and mechanisms that the central nervous system uses to assimilate and integrate the sensory information with previous experiences.
    Motor control
  41. Groups of muscles that are recruited by the central nervous system to provide movement
    Synergies
  42. % of population that experiences low back pain
    # ACL injuries that occur yearly
    • 85%
    • 80,000-100,000
  43. The cumulative sensory input to the cns from all mechanoreceptors that sense position and limb movements.
    Proprioception
  44. The ability of the nervous system to gather and interpret sensory information and select and execute the proper motor response.
    Sensorimotor integration
  45. repeated practice of motor control processes, which lead to a change in the ability to produce complex movements.
    motor learning
  46. the use of sensory information and sensorimotor integration to help the kinetic chain in motor learning
    feedback
  47. The process whereby sensory information is used by the body via length-tension relationships (posture), force-couple relationships, and arthrokinematics to reactively monitor movement and the environment.
    Internal feedback
  48. Information provided by some external source, such as health and fitness professional, mirror, heart rate monitor
    External feedback
