Name the three types of muscles.
Cardiac, Smooth and Skeletal
1 of 17
What are Antagonistic Pairs?
The way in which muscles work together, contracting then relaxing.
2 of 17
What is an Agonist (Prime Mover)?
It is the main muscle that is responsible for the movement.
3 of 17
What is the Antagonist?
It is the opposite muscle that relaxes, allowing movement to occur.
4 of 17
What is a Synergist?
The muscle that helps the agonist.
5 of 17
What is a Fixator?
Muscle that helps to stabilise the joint at the origin of the agonist.
6 of 17
Name the three fibre types.
Type 1, Type 2a and Type 2x.
7 of 17
Name three features of Type 1.
Long distance, Aerobic and Slow twitch
8 of 17
Name three features of Type 2a.
Fast oxidative fibres, Resistant to fatigue and Good force.
9 of 17
Name three features of Type 2x.
Fast glycolytic fibres, Fatigues easily and Anaerobic.
10 of 17
Name three respsonses to the muscular system in short term.
Increased blood supply, Increased muscle temperature and Production of lactate (OBLA).
11 of 17
What is Stroke Volume?
The amount of blood that is pumped out of the heart per beat.
12 of 17
What is Cardiac Output?
The amount of blood that is coming out of the heart after one minute.
13 of 17
What is an Isometric Contraction?
The joint angle and the muscle length does not change during the contractions.
14 of 17
What is an Eccentric Contraction?
The muscle lengthens as it contracts.
15 of 17
What is a Concentric Contraction?
It causes the muscles to shorten as they contract.
16 of 17
Name five long-term changes to the muscular system during exercise.
Hypertrophy, Increase in mitochondria, Increase in storage of fat, Increase in tolerance of lactate and Increase in myoglobin stores.
