rigid body - object of non-zero size that cannot change shape position - location and orientation CoG - average location of all weight of an object (typically in midline a bit below navel of humans) orientation in space - position with respect to the points of a compass or other directions motion of rigid body - change in position denoted by its location and orientation at every instant in time) distance - total distance travelled (SI unit: m) displacement - how far an object is from i...

Coronal plane (frontal) - - Divides the body into anterior + posterior portions - Z, Y Plane - X Axis Axial Plane (Transverse) - - Horizontal plane, divides the body into upper + lower parts - X, Z Plane - Y Axis Sagittal Plane - - Vertical plane that divides the body into right + left parts - Y, X Plane - Z Axis Valgus - - Distal segment of a joint deviates laterally Varus - - Distal segment of a joint deviates medially Contact Patch - - Portion of your body that is in contact w/ ...

Centre of Gravity vs Centre of Mass - centre of mass depends on the distribution of mass (not gravitational field) and it doesn't change even if you move or orient yourself differently. Centre of gravity is a unique point which weight is balanced, it can change based on orientation and also takes into account mass distribution. Is it harder to lift or lower a mass? Which feels harder and why? - It takes the same amount of force. When you're applying a force greater than the weight its...

Space - distance is the linear measure of space (m,km,cm) Space and planar angle - a figure made by two intersecting lines or planes, an angular measure of space (radians, degrees, revolutions) Time - monotonically increasing quantity (s) Matter - Anything that has mass and takes up space Mass(m) - how much matter is in a material body (kg) Volume(V) - How much space an object takes up (L) Density(p) - mass(m)/volume(v)

What are the two types of movement? - Active (endogenous) and Passive (exogenous) What is active movement? - - Movement that results fro muscular contractions - voluntary movements - reflexes What is passive movement? - - Movement that results from external forces - gravity - supportive devices - other bodies What are the types of action? - Reflex action and voluntary action (motor skill) What is reflex action? - - involuntary and relatively stereotyped response to a specific stimulus...

Kinematics - describing where something is when - describing movement Kinetics - Body Segments - you can divide a body into a number of segments based on our bones Anatomical Position - spine in neutral position - Anatomic planes and positions _____ with the body - move Types of Anatomic Directions - Global Local Embryonic Global Directions ________ with the body - do not move Local Directions _____ with the body - move examples of global directions - superior (above

human nervous system - CNS: brain and spinal cord encased by skull and vertebrae PNS: neurons and nerve processes outside CNS motor control - mechanisms underlying movement motor learning - study of mechanisms in acquiring and improving motor skills processes associated with practice or learning leading to relatively permanent changes in movement capabilities motor development - changes in motor behavior reflecting its interactions as it grows multidimensional and multidirectional lifelo...

Anatomical Position - spine in neutral position, eyes straight forwards, arms and forearms at side with elbows extended and hands supinated, feet together with knees and hip straight, penis erect Sagittal Spinal Curves - Lordosis and kyphosis Frontal Spinal Curve - scoliosis Transverse Spinal Curve - rotoscoliosis Base of Support - the area circumscribed by the outermost parts of your contact patch Contact Patch - the portion of the body that is in contact with the earth's surface

health - The dynamic, ever-changing process of trying to achieve individual potential in the physical, social, mental, occupational, emotional, environmental, and spiritual dimensions what are the changing views of health - • Absence of disease • Good hygiene • "complete physical, mental, and social wellbeing, not merely the absence of disease or infirmity" what are the dimensions of health and wellness - 7: physical, social, mental, occupational, emotional, environmental, spir...

Subdivisions of motor behaviour - motor control, motor learning, motor development Goal of motor control - to understand the set of cognitive and neural processes involved in the planning and execution of individual actions Goal of motor learning - to understand the set of challenges and processes of improving and perfecting a performance Goal of motor development - to understand the set of processes and factors leading to changes in performance and learning across the lifespan Cogniti...
