A

Sit deep in front of the hip and connect the leg

27
Q

What is the function of the Hip Flexors?

A

Flex the hip, help the leg and knee up towards the body

28
Q

What is a sporting example of when Hip Flexors are being used?

A

At the top of each leg at the front

30
Q

What is the function of the Quadriceps

A

Extend the leg at the knee

31
Q

What is a sporting example of when the Quadriceps are being used?

A

Extend the legs in long jump

32
Q

What are voluntary muscles?

A

Muscles under your control - these muscles are attached to the skeleton via tendons.

33
Q

What do voluntary muscles look like

A

When they are relaxed, they are long and thin
When they are contracted, they become short and fatty.

34
Q

How do voluntary muscles improve our performance in sport?

A

They work in antagonistic pairs in order to do the correct movements

35
Q

What are involuntary muscles?

A

Not under our control

36
Q

What are Slow twitch (type 1) fibres?

A

Suit endurance activities - can work for long periods of time
- darker in colour because they contain MYOGLOBIN, a red pigment that transports oxygen to the working muscles.

37
Q

What are Fast twitch (type II) fibres?

A
  • Suit speed events, such as sprinting or jumping
  • Are lighter in colour because they don’t use oxygen for energy
38
Q

What are Type IIa fibres?

A
  • used in anaerobic work which can be improved through endurance training. Increase their resistance to fatigue
39
Q

What are Type IIx fibres?

A

Used in anaerobic work that can generate more power that other muscle fibres but fatigue quickly

40
Q

Where are the hamstrings located?

A

At the top of each leg at the back

41
Q

What is the function of the hamstrings?

A

Flex the leg at the knee

42
Q

What is a sporting example of when the hamstring is being used?

A

Backswing of a kick

43
Q

Where is the gastrocnemius muscle located?

A

At the bottom of each leg at the back. Also known as the calf muscles

44
Q

What is the function of the gastrocnemius muscle

A

Point the toes (planta-flexion) at the ankle

45
Q

What is a sporting example of when the gastrocnemius is being used?

A

Kicking a ball

46
Q

Where is the Tibialis anterior located?

A

Runs down the shin

47
Q

What is the function of the tibialis anterior

A

Flex the hip, help the leg and knee up

48
Q

What is a sporting example of when the tibialis anterior would be used

A

Control a football from the air

49
Q

What are voluntary muscles?

A

Voluntary muscles are under your control.
Attached to skeleton via tendons.
Usually made up of cylinder shaped fibres
usually long and thin but get shorter and fatter when contracted

50
Q

What are involuntary muscles?

A

Involuntary muscles are not under your control
They contract and relax automatically controlled by the involuntary nervous system.
They can be found in the digestive organs, circulatory and urinary systems.

Usually made up of spindle shaped fibres. The involuntary muscles of the blood vessels are especially important for sport.
By the muscles contracting and relaxing it helps distribute blood to areas it is most needed

51
Q

What are cardiac muscles?

A

Only found in the wall of the heart it is a very specialises type of involuntary muscle

Cardiac muscle is made up of interlaced fibres.

These fibres can spread electronical signals from the brain right through the heart so that all the cells can contracf together.

This regulated your heart rate and means that when you exercise your heart keeps pumping in the right way

52
Q

The quadriceps are part of an antagonistic pair with which other muscle?

A

Hamstrings

53
Q

The hanstrings are part of an antagonistic pair with which other muscle?

A
