Joint Movement, Joint Axis, Axis Of Rotation, Locomotion

Question 1

What are the planes of the body?

Answer 1

1. Sagittal plane (separates left and right)
2. Frontal plane (separates anterior and posterior)
3. Transverse plane (separates superior and inferior)

Question 2

What are the axis of the body?

Answer 2

1. Frontal axis ( sp = fa)
2. Sagittal axis (fp = sa)
3. Vertical axis (tp = va)

Question 3

Locomotion (fundamental movement patterns)

Answer 3

Locomotion is a type of linear movement, linear is a type of non stationary movement

Question 4

Locomotion positions

Answer 4

• front support
• back support
• cross support
• hangs

Question 5

Locomotion locations

Answer 5

• floor
• beam
• bars — horizontal, parallel
• rope

Question 6

Spring mechanics (last slide why??)

Answer 6

1. Increase the force of take off muscles
2. Maintain rigidity
3. Utilize non contact limbs to enhance force

Question 7

What is locomotion? Key feature?

Answer 7

Movement pattern in which the body repetitively moves outside the base of support

Key feature is the repetition of a basic motor activity

Question 8

Where does locomotion take place?

Answer 8

In Supports, in hangs, and on the feet

Question 9

What is a spring?

Answer 9

Single dynamic takeoff

Question 10

For rotations, what are the 3 axes that the body rotates about?

Answer 10

1. Longitudinal axis (twists)
2. Transverse axis (rolls)
3. The anterior/posterior axis (cartwheel)

Question 11

How are rotations caused?

Answer 11

By off-centre forces (force not passing through the centre of mass) any force that is passing through the centre of mass will only generate linear motion (displacement)

Question 12

The further off-centre the force:

Answer 12

• The greater will be the rotation
• the less will be the displacement

Question 13

Force couple

Answer 13

2 forces rotating the body
Ex. Force from leg push, force from feet stopping after a fast run
