1 Muscles and Movements Analysis
Lesson 7 Muscles and Movements Analysis

2 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.

3 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.

4 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 foot

5 Muscles and Movements Look at the examples of the judo kick, basketball dribble, chest pass and lay up For each joint labeled you are to name : Type of joint Movement being performed Agonist and antagonist muscles ANALYSE THE PHASE, NOT THE STATIC MOVEMENT

6 Judo Kick Phase B – C 1. Knee 2. Elbow Joint - Movement - Agonist -
Antagonist - 2. Elbow A B C D E

7 Judo Kick Answers Judo Kick – Phase B-C 1. A. Hinge B. Extension
C. Agonist – Quadriceps Antagonist - Hamstrings 2. A. Hinge C. Agonist – Triceps Brachii D. Antagonist – Biceps Brachii

8 Basketball Dribble Phase B – C 1. Right Hip Phase C - D 2. Right Elbow
Joint - Movement - Agonist - Antagonist – Phase C - D 2. Right Elbow Antagonist - B - C - D - A -

9 Answer Phase B – C 1. Right Hip Phase C - D 2. Right Elbow
Joint – Ball and Socket Movement – Hip Flexion Agonist – Quadriceps and Hip Flexors Antagonist – Gluteus Maximus Phase C - D 2. Right Elbow Joint - Hinge Movement – Elbow Extension Agonist – Triceps Brachii Antagonist – Biceps Brachii

10 Chest Pass Phase B – C 1. Right Wrist Phase B - C 2. Right Shoulder
Joint - Movement - Agonist - Antagonist – Phase B - C 2. Right Shoulder Antagonist - 3. Right Elbow A - B - C -

11 Phase B – C 1. Right Wrist Phase B - C 2. Right Shoulder
Joint - Gliding Movement – Wrist flexion Agonist – Wrist flexors Antagonist – Wrist extensors Phase B - C 2. Right Shoulder Joint – Ball and Socket Movement – Shoulder Flexion Agonist – Anterior deltoid and Pectoralis major Antagonist – Posterior deltoid and latissimus dorsi 3. Right Elbow Joint - Hinge Movement – Elbow extension Agonist – Triceps brachii Antagonist – Biceps brachii

12 Lay Up Phase B – C 1. Left Hip Phase A - B 2. Left Ankle 3. Left Knee
Joint - Movement - Agonist - Antagonist – Phase A - B 2. Left Ankle Antagonist - 3. Left Knee (Your left/right when looking at the picture) - C - B - A

13 Answers Phase B – C 1. Left Hip Joint – Ball and Socket
Movement – Hip Extention Agonist – Gluteus Maximus Antagonist – Hip Flexor and Quadriceps Phase A - B 2. Left Ankle Joint - Condyloid Movement – Planta-flexion Agonist – Gastrocnemius Antagonist – Tibialis Anterior 3. Right Knee Joint - Hinge Movement – Knee Extension Agonist - Quadriceps Antagonist – Hamstrings

14 Complete worksheet: Angle Increasing or Decreasing?

15 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.

16 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!
