1

Name the 3 planes of motion

Sagital, frontal, and transverse

2

Divides body into right and left half. Flexion and extension. Walking, squatting, curling, ab crunches

Sagital plane

3

Divides body into back ad front. Side to side motions. Adduction or abduction, Lateral flexion, inversion, eversion (Lateral raises, side lunges, side shuffles)

Frontal Plane

4

Divides body into top and bottom half. Rotation motions and horizontal adductions. (Spine rotation, shoulder rotation, Hip rotation, throwing, golfing, swinging a bat)

Transverse Plane

5

Force is produced, muscle tension is developed, and movement occurs through a given range of motion. "constant tension"

Isotonic

6

3 muscle actions

Concentric, isometric, and eccentric

7

moving in the same direction as the resistance. Decelerates. Reduced force

Eccentric

8

Moving in the opposite direction of force. Accelerates, Produces force

Concentric

9

No movement with or against resistance. Dynamically stabilizes force.

Isometric

10

The speed of mvmnt is fixed and resistance varies with the force exerted. Requires special equipment.

Isokinetic

11

Tension while shortening or accelerating

Concentric

12

Tension while lengthening or deceleration

Eccentric

13

Muscle groups moving together to produce a joint movement

Force couple

14

resting length of a muscle and the tension the muscle can produce at resting length

Length tension relationship

15

Movement of bones around joints

rotary motion

16

Force that produces rotation

Torque

17

Difference between external and internal feedback

Internal: uses sensory info for feedback
External: provided by an outside source

18

Muscles ability to produce tension @ differing shortening velocities

Force velocity curve
Concentric = decreases force production
eccentric= increases " "

19

Misaligned joints Like tight quads preventing the hamstrings from using appropriate force is an examples of

altered length relationship

20

Science concerned with internal and external forces and the effects produced by these forces

Biomechanics

21

Above reference point

Superior

22

Below reference point

Inferior

23

Closest to reference point

Proximal

24

Furthest from reference point

distal

25

Front

Anterior

26

Back

Posterior

27

Towards mid line

medial

28

Away from midline

Lateral

29

Opposite side of body

contralateral

30

Same side of body

Ipsilateral
