Muscles and Movements Analysis

Lesson 7Slide2

Quick Re-cap

What is the anatomical position?

What are 3 examples of types of movement?

What is another term used for Agonist?

Define Agonist or ________?

Define Antagonist

What type of joint is your shoulder?

Name the 3 other joints that you have learnt and give an example for each.Slide3

Answers

Anatomical Position - the body is assumed to be standing, the feet together, the arms to the side, and the head and eyes and palms of the hands facing forwards.

Flexion, Abduction,

Pronation

, etc

Prime Mover

The agonist or prime mover is the muscle which

contracts

and

shortens

to

cause

a movement.

The antagonist is the muscle which

relaxes

and

lengthens

to

allow

a movement to occur.Slide4

Answers Cont.

Ball and Socket – Shoulder

Hinge – Elbow, Knee

Pivot – Where the atlas pivots around the axis at the top of the spine

Gliding/ Condyloid – Between the small bones of the wrist and footSlide5

Question: Explain how muscle movement occurs during the bicep curl?

Muscles can

only pull

, they cannot push. They

work in pairs

to create movement, where one contracts while the other relaxes and lengthens.

The hinge joint at the elbow starts in an extended position for the bicep curl. The agonist muscle is the bicep

brachii

, also known as the

prime mover

,

contracts (shortens) to create the movement of flexion. The antagonist muscle, the tricep brachii, relaxes (lengthens) to allow movement to occur.Slide16

Homework

Find a picture of a person involved in a sporting event.

Bring tomorrow as you will be analysing the muscles and movements.

Make sure you are still revising everything you have learnt so far!
