What is biomechanics? | Study of application of mechanics of structure and function of biological systems |
What is kinesiology? | Scientific study of human movement |
What is linear motion? | Movement along a straight or curved pathway |
What are some examples of linear motion? | Sprinter, path of baseball, path of bench press bar |
What is angular motion? | Motion around a point where different regions of the same segment don't move through the same distance |
What are some examples of angular motion? | Around an axis through a joint, through a COG, gymnist on uneven bars |
What is kinematics? | Focuses on amount and type of movement, the direction of movement, and speed or change of speed of the object |
What is kinetics? | Examines the forces acting on a system such as the human body |
What do kinetics focus on? | The cause of the movement |
What is included in the axial skeleton? | Head, neck, thorax, pelvis |
What is lateral or ER? | Movement of a segment around a vertical axis running through the segment so that the anterior surface of the segment moves away from the midline, while posterior surfaces moves toward the midline |
What is another name for protraction of the scapula? | Abduction |
What is another name for retraction of the scapula? | Adduction |
What is another name for upward rotation of the scapula? | Lateral rotation |
What is another name for downward rotation of the scapula? | Medial rotation |
What is upward/lateral rotation of the scapula? | When scapulas swing out so that the bottom of the scapula move away from the trunk |
What is downward/medial rotation of the scapula? | When scapulas swing down back into resting position towards trunk |
How are upward/lateral and downward/medial rotation of the scapula described? | By the inferior angle of the scapula |
What is tipping of the scapula? | When inferior portion of scapula moves away from thorax |
What is winging of the scapula? | When the medial border of the scapula move away from thorax |
What is horizontal adduction a combination of? | Flexion and adduction |
What is horizontal abduction a combination of? | Extension and abduction |
What is the combined set of movements in pronation of ankle? | DF of ankle, eversion of tarsals, abduction of forefoot |
What is the combined set of movements in supination of ankle? | PF of ankle, inversion of tarsals, adduction of forefoot |
What is the absolute reference system? | Movement of the segment is described with reference to a fixed angle |
What is the relative reference system? | The movement segment is described relative to the adjacent segment |
