Re-cap

Very important……………

Have we learnt?

Quick fire questions!

Page 3: Muscle fibre types

Can you spot each connective structure?

Articulate

-Tendon-Epimysium-Fascia-Bundles of muscle fires-Perimyisum-Muscle fibre-Myofilament-Actin-Myosin

Try and describe the basic structure of muscle by looking at this picture

Page 5: Muscle fibre types

AimsDescribe structure and function of Type 1, Type

2a and Type 2b (P4)

Review how recruitment patterns vary (M4)

Describe the ability for the muscle fibres to adapt with increased long term activity and detraining (P4)

Analyse the different structures and how each sports may require ranging fibre types (D4)

Muscle Fibre Types

Type 2 fibres subdivide:

Type 2a – Fast oxidative glycolytic (FOG)Type 2b – Fast glycolytic (FG)

What sports would lend them selves to each type 2 fibres?

Endurance Force

What doesthis tell us?

Can we apply it to other Characteristics?

Fibre Type ConsiderationsMost potential is based on genetics

Specific training can develop respective fibre types (E.g. Clean and jerk for Fast Glycotic)

Detraining will result in the loss of F.O.G & F.G to Oxidative

Recovery (Timings)? Nutrition? Sleep? Tapering?

Task

We are going to look at certain words related to fibre types

With your study buddy, try and compare each fibre type

Include different sports for each

If you don’t know a term yet, feel free to use mobile devices to research

Oxidative F.O.G F.G

Glycogen stores

Moderate Highest

Fatigability Moderate

Force Produced

Low

TermsStructure What is it? Also see

these as clues! E.g. if it needs oxygen it will probably be….

Glycogen Stores Carbohydrate stored in the muscle and liver

Myoglobin Found in muscle tissue. An oxygen-binding protein.

Capillary Density The amount of capillaries found in the muscle

Mitochondrial Density

Powerhouse of the cell. Help to convert food into energy.

Triglyceride Stores Fat stores in the body

It is nearly Christmas!

Let’s turn answers into merit and distinctions!
