Section Two-Movement analysis

Question 1

What is the sagittal plane?

Answer 1

divides the body between the Left and Right sections

Question 2

What is the transverse plane?

Answer 2

Divides the body into top and bottom sections

Question 3

What is the Frontal plane?

Answer 3

Divides the body into front and back sections

Question 4

What movements occur around the sagittal plane?

Answer 4

Flexion and extension

Question 5

What movements occur around the transvers plane?

Answer 5

Rotation - torso twists with a medicine ball

Question 6

What movements occur around the frontal plane?

Answer 6

Abduction/Adduction

Question 7

what are the three planes of movement?

Answer 7

Sagittal, Transverse and Frontal

Question 8

What are the three axis of movement?

Answer 8

Sagittal, Transverse and longitudinal

Question 9

What is the Sagittal Axis?

Answer 9

A pole going from front to back by which you rotate

Question 10

What is the Transverse Axis?

Answer 10

A pole going from left to right by which you rotate

Question 11

What is the Longitudinal Axis?

Answer 11

A pole going from top to bottom through your body by which you rotate.

Question 12

What movement occurs along the Sagittal Axis?

Answer 12

Rotation - A cartwheel

Question 13

What movement occurs along transverse Axis?

Answer 13

Rotation - Somersault/front flip

Question 14

What movement occurs along the longitudinal Axis?

Answer 14

Rotation - A 360’ twist

Question 15

How would you describe running in terms of planes and axis?

Answer 15

In the sagittal plane about a Transverse axis

Question 16

How would you describe a cartwheel in terms of planes and axis?

Answer 16

IN a frontal plane about a sagittal axis

Question 17

How would you describe a 360 spin in terms of axis and planes?

Answer 17

in a transverse plane about a longitudinal axis

Question 18

What is a lever?

Answer 18

a solid bar that moves about a fixed point when force is applied to it.

Question 19

How does the body use levers?

Answer 19

When a muscle pulls on a bone to move a part of the body about a joint

Question 20

What is the lever arm?

Answer 20

the bone or body part being moved about a point

Question 21

What is the effort?

Answer 21

the force applied by the muscles to the leaver.

It is represented by a arrow pointing in the direction of the force.

Question 22

What is the fulcrum?

Answer 22

The joint where the lever arm pivots. It is shown by a triangle

Question 23

What is the load?

Answer 23

the resistance against thepull of the muscles on the lever arm. a sqaure is used to represent the load.

Question 24

What is a 1st class lever system?

Answer 24

The load and effort are at opposite ends of the lever. the fulcrum is in the middle. Tilting your head back is a first class lever. EFL

Question 25

what is a 2nd class lever system?

Answer 25

The fulcrum and effort are at topposite ends of the lever. The load is in the middle. Standing on your toes uses a second class lever system. FLE

Question 26

What is a 3rd class lever system?

Answer 26

The fulcrum and load are at opposite ends of the lever . the effort is in the middle. Flexion at the elbow uses a third class lever system. FEL

Question 27

What is the acronym used to remeber the three lever systems?

Answer 27

EFL the FLE FEL

Question 28

What is a mechanical advantage?

Answer 28

When a lever can move a large load with a small effort from the muscles. (only moves small distances slowly)

Question 29

When does a lever have a mechanical?

Answer 29

when the distance from the fulcrum to the effort is greater than the distance from the fulcrum to the load.

Question 30

What classes always have mechanical advantage?

Answer 30

2nd class lever and some times the first class

Question 31

How do u calculate mechanical advantage

Answer 31

Effort arm/resistance

Question 32

What is concentric and escentric muscle contraction

Answer 32

Concentric: muscle which lengthens Eccentric: muscle which shortens Check

Question 33

How do you calculate mechanical advantage?

Answer 33

effort arm/resistance arm
