Terminology Of Kinesiology

Question 1

What are the kinematic variables

Answer 1

Types of motion
Location of motion
Direction of motion
Quantity of motion

Question 2

What types of motion are there

Answer 2

1. Rotatory (angular)
2. Translatory (linear)

Question 3

Rotatory (angular) motion

Answer 3

Movement of an object or segment around a fixed axis

Question 4

Translatory (linear) motion

Answer 4

Movement of an object or segment in a line

Question 5

Open kinetic chain

Answer 5

The distal moves on the proximal

Question 6

Closed kinetic chain movements

Answer 6

Proximal moves on the distal

Question 7

Transverse plan

Answer 7

“X-coordinate”
Has a vertical/longitudinal axis
IR/ER and rotational movements occur in this plane in anatomical position

Question 8

Frontal plane

Answer 8

“Y-coordinate”
Anterior to posterior axis
In the anatomical position abduction and adduction, later flexion occur

Question 9

Sagittal plane

Answer 9

“Z-coordinate”
Coronal/medial lateral axis
In anatomical position flexion and extension occur

Question 10

Force vectors

Answer 10

Point of application
Action line of direction
Spatial orientation
Magnitude

Question 11

Point of application

Answer 11

Where the force is acting (shown by the base of the arrow)

Question 12

Action line of direction

Answer 12

Point of the arrow

Question 13

Spatial orientation

Answer 13

Shaft of the arrow

Question 14

Magnitude

Answer 14

Length of the arrow

Question 15

Compression force

Answer 15

Two surfaces together along the long axis
Demons by shortening and widening

Question 16

Tension or distraction force

Answer 16

Two surfaces moving apart along long axis
Deforms by lengthening and narrowing

Question 17

Bending

Answer 17

2-3 contact points around an external axis
Deforms: Compression on one side and tension of the other

Question 18

Torsion

Answer 18

Twisting; forces in opposite directions around internal axis
Can be a combination of tension/compression and shearing forces
Deforms:

Question 19

Shearing force

Answer 19

Loads applied in opposite directions parallel to surface of structure
Rug burn/tearing ACL

Question 20

Friction

Answer 20

External force that is a resistance to movement

Question 21

Kinesiology

Answer 21

study of human movement

Question 22

kinematics

Answer 22

description of motion

Question 23

Rectilinear motion

Answer 23

movement occurs in a straight line

Question 24

Curvilinear motion

Answer 24

movement around a a curved line
ex: when walking the center of the head raises and lowers in a curvilinear way

Question 25

quantity of motion

Answer 25

includes range of motion in degrees, angular velocity in degrees per second, and transltory motion (linear distances)

Question 26

describe motion and the rule of threes

Answer 26

which segments (bones) are moving? what is the direction of the motion which joint is it occurring at

Question 27

kinetics

Answer 27

study of the mechanics that describe the effect of forces on the body application of forces to systems and the effect on the system with groups of forces
