Q

How do the long term effects of exercise on the muscular system benefit the body when taking part in physical activity?

A
  1. You are more able to perform activities requiring strength, power and muscular endurance
  2. Improves immediate oxygen supply to the muscles
  3. Better support of joints
23
Q

Why is it important that the muscular system has time to rest?

A

To allow muscles to repair and grow after exercise

24
Q

What is it important to eat as part of your balanced diet to aid the muscular system?

25
Q

What performance enhancing drug builds and develops the strength of muscles?

A

Anabolic Steroids

26
Q

What is the name of the injury that is common to the muscular system?

27
Q

How should you treat a muscle strain?

A

RICE (Rest, Ice, Compression and. Elevation)

28
Q

What does muscle ‘atrophy’ mean?

A

Loss of muscle mass and strength, this is often by stopping training

29
Q

What are all the bones on the front of the body?

A 
Deltoids 
biceps
Quadriceps 
Pectoralis major
External obliques 
Tibialis anterior 
Hip flexors
30
Q

What are all the bones in the back side of the body?

A 
Gluteals 
Hamstrings 
Gastrocnemius 
Latissimus Dorsi
Triceps
31
Q

What do fast twitch fibres do?

A

Works fast but tire quickly

32
Q

What do slow twitch fibres do?

A

Work slow but tire slowly

33
Q

Antagonistic pairs

A 
Biceps & Triceps
Hamstrings & Quadriceps
Gluteus maximus & Hip flexors
Gastrocnemius & Tibialis anterior
Pectoralis major & Latissimus dorsi
34
Q

Synergists

A

These muscles perform, or assist in performing, the same set of joint motion as the agonists. Synergists are sometimes referred to as neutralizers because they help cancel out, or neutralize, extra motion from the agonists to make sure that the force generated works within the desired plane of motion.

35
