Q

In preparation for jumping for a header in football, the hip and knee go through flexion and ankle goes through dorsi flexion. What type of contraction is occurring at these joints?

Q

For your AS exam what sporting actions must you be familiar with at the shoulder and elbow joints?

A

Push ups
Over arm throwing
Forehand racket shots

16
Q

For your AS exam what sporting actions must you be familiar with at the elbow, hip and knee joints?

A

Running
Kicking
Squats
Jumping

17
Q

If a performer holds their squat position for 5 seconds, what type of muscle contraction is taking place?

A

Isometric

The muscle is under tension but does not change in length

18
Q

A tennis player brings their arm forwards to strike the ball with their racket. What joint action occurs at the shoulder as they bring their arm through to hit the ball?

A

Horizontal flexion

Horizontal adduction

19
Q

What is the mechanical advantage of a second class lever?

A

A large weight / resistance can be lifted

20
Q

What is the mechanical advantage of first and third class levers?

A

They can apply speed to an object

They have a large range of movement

21
Q

When would a third class lever be used in the body?

A

All joint actions except;
Extension at the elbow
Plantar flexion at the ankle

22
Q

When preparing to jump a player lowers their body weight in an eccentric contraction. Which muscles are responsible for flexion at the hip and knee?

A

Hip - gluteals and hamstrings

Knee - quadriceps

23
Q

When lowering the body in a press up an eccentric muscle contraction occurs. Which muscles are responsible for flexion at the elbow and horizontal extension at the shoulder?

A

Elbow - triceps

Shoulder - anterior deltoid and pectoral is major

24
When running a performer will raise their recovery leg causing flexion at the hip and knee and dorsi flexion at the ankle. Which muscles are responsible for these actions?
Hip - rectus Femoris / quadriceps (hip flexors) Knee - hamstrings Ankle - tibial is anterior
25
When preparing to throw over arm the performer brings their arm back wards, what joint action at the shoulder is occurring?
Horizontal extension
26
What joint action operates at the shoulder when releasing a ball in an over arm throw?
Horizontal flexion
27
When throwing a performer will use horizontal extension, which muscles are responsible for this joint action?
Posterior deltoid and latissimus dorsi
28
Which joint action operates at the ankle in the upwards phase of a squat?
Plantar flexion
29
Which bones articulate at the shoulder joint?
Scapula | Humerus
30
Which bones articulate at the elbow joint?
Humerus Radius Ulna
31
Which bones articulate at the hip joint?
Pelvis (acetabulum - socket) | Femur
32
Which bones articulate at the knee joint?
Femur | Tibia
33
Which bones articulate at the ankle joint?
Tibia Fibula Talus
34
What is the mechanical disadvantage of a 2nd class lever system?
Decreased range of movement at the joint | Decreased speed of movement
35
What is the mechanical disadvantage of 1st and 3rd class lever systems?
They cannot move very large weights / heavy resistance
36
When a performer lowers themselves down in the downwards phase of a jump, what joint action is occurring at the ankle joint?
Dorsi-Flexion An angle less than 90 degrees at the ankle is Dorsi-Flexion. An angle 90 degrees or greater is Plantar-Flexion
