2 PASSMERITDISTINCTION P3: IDENTIFY the LOCATION of the MAJOR MUSCLES in the human body P4: DESCRIBE the FUNCTION of the MUSCULAR SYSTEM and the different FIBRE TYPES M1: EXPLAIN the FUNCTION of the MUSCULAR SYSTEM and the different FIBRE TYPES D1: ANALYSE the FUNCTION of the MUSCULAR SYSTEM and the different FIBRE TYPES

3 VERBPLAIN ENGLISH Describe Try to “Paint a picture” in words. Assume that the person that you are Describing to does not know anything about the subject that you are describing. Tell them what you have learned. Identify Create a List of KEY FEATURES.(e.g) Steven Gerrards Strengths are: Aerobic Endurance, Goal scoring ratio etc…. Explain Once you have Described the subject, often you will need to give further details and reasons why. (e.g) Once you have described England’s poor performance in the World Cup, you may also give some reasons why the players did not perform as well as they could. AnalyseYou need to SELECT the KEY POINTS and EXPLAIN each point providing REASONS for each point and also looking at POTENTIALIMPACTS.(e.g.) If you were looking at the performance of Barcelona you may pick out the key points in their success – Money, Lionel Messi, Iniesta etc.. You would then explain the contribution of each player and also look at what the club could do to regain the Champions league next season

4 Vastus Intermedius

5 Skeletal Smooth Cardiac

6 Also called Stripy/striated muscle Voluntary – Under Conscious control Over 700 skeletal muscles in the body Attached to bones Is made up of different muscle fibres

7

8 Involuntary – Works without thought Found in the walls of hollow internal structures such as blood vessels, the stomach, intestines, urinary bladder A smooth muscle is non-striated (smooth) Peristaltic Action – Contract consecutively, one after the other

9

10 Found in the walls of the heart Its contraction is involuntary (not under conscious control) Pumps blood around the body, without getting tired It is striated (has light and dark bands)

11

12 Muscles cross joints that they move Pulling force from muscles causes movement Muscle Tone – State of readiness to work Strength of contraction – Depends on the number of fibres that have been recruited

13 Antagonistic Muscle Pairs Muscles work together in groups to create movement Muscles can function as the following: Agonist, Antagonist, Synergist, Fixator.

14 Shortens to move a joint Also called the PRIME MOVER

15 Relaxes when the agonist muscle is working Has a BRAKING effect

16 Synergist = Muscles that help the agonist muscle Fixator = Stop unwanted movement Stabilise the movement

17 Isometric Concentric Eccentric Isokinetic

18 Muscle tenses Stays the same length Joint angle stays the same E.G. Holding a Press-up

19 Muscle shortens under tension Origin and Insertion move closer together

20 Muscle lengthens under tension Origin and Insertion move further apart E.G. Bicep Curl – Lowering Phase

21 Muscle contracts at a CONSTANT SPEED Need specialised equipment that controls the muscle action

22 There are three types of muscle fibre: Type 1 Type 2a Type 2b

23 Contract slowly Lots of blood vessels Low Force Fatigue resistant Low Intensity, Long duration activities

24 Type of Fast Twitch Fibres Fast Contractions Produce Force Resistant to Fatigue E.G. Middle Distance Runners

25 Type of Fast Twitch Fibres Fast Contractions Lots of Force Fatigue quickly Anaerobic Activities E.G. 100M
