Muscle Fibres

Question 1

How many type 1 characteristic

Answer 1

5

Question 2

Hi name the 5 features of type 1

Answer 2

High capillary density
High myoglobin in content
High mitochondria levels
high levels of oxidative enzymes
High levels of triglyceride


Question 3

High capillary density

Answer 3

Increase number of sites available for diffusion

Question 4

High myoglobin

Answer 4

More oxygen can be extracted from the bloodstream

Question 5

High mitochondria levels

Answer 5

Where aerobic respiration takes place, more sites available

Question 6

High levels of oxidated enzymes

Answer 6

Increases the rate of aerobic respiration and speeds up the removal of lactic acid

Question 7

High levels of triglyceride

Answer 7

Can be used to produce fatty acids for energy production

Question 8

How many characteristics of type IIB

Answer 8

4

Question 9

Characteristics of Type IIB

Answer 9

High stores of PC
High stores of glycogen
High levels of anaerobic enzymes
Large motor neurons

Question 10

Type two b muscle fibres are used during

Answer 10

Anaerobic and explosive sports.
Fast speed high contraction of force

Question 11

High PC stores

Answer 11

Allows the performer to use ATP-PC

Question 12

High stores of glycogen

Answer 12

Can be used as an energy source for lactate anaerobic

Question 13

High levels of anaerobic enzymes

Answer 13

Allows us to break down energy sources e.g ATPase

Question 14

Large motor neuron

Answer 14

Allows for more muscle fibres per never impulse, increases force of contraction

Question 15

Adaptations of aerobic exercise is also the

Answer 15

Physiological and structural features that increase VO2 max

Question 16

How many aerobic adaptations

Answer 16

5

Question 17

How many anaerobic adaptations

Answer 17

4

Question 18

Name the aerobic adaptations

Answer 18

Cardiac hypertrophy
Increase % of alveoli used
Increase myoglobin used
Increase mitochondria density
High stores if triglycerides

Question 19

Cardiac hypertrophy

Answer 19

Heart gets bigger and stronger -

increases stroke volume, amount of blood pumped out of ventricle per beat.

+ increases cardiac output

Increases transport of oxygen to muscles

Question 20

Increase % of alveoli used

Answer 20

More sites for diffusion in the lungs - rate of diffusion from the alveoli to capillary increases.
Increases capacity to transport oxygen to muscles
Can remove more lactic acid via oxidation

Question 21

increase myoglobin content

Answer 21

extracts oxygen from the blood stream into the working muscles
increases the rate of diffusion of oxygen
allows to resynthesis ATP aerobically
reduces risk of fatigue

Question 22

increased mitochondria

Answer 22

where aerobic respiration takes place

Question 23

high stores of triglyceride

Answer 23

can be broken down into fatty acids
used in aerobic respiration

Question 24

adaptations of anaerobic exercise

Answer 24

hypertrophy of fast twitch muscle fibers
increased recruitment of motor units
high PC stores
increased strength of tendons and ligaments and bones

Question 25

hypertrophy of fat switch muscle fibers

Answer 25

causes muscle fibers to become thicker in diameter leading to an increased force of contraction of each fiber
power increases

Question 26

increased recruitment of motor units

Answer 26

increased ability to contract and control fibers
increases force of contraction
increase power

Question 27

high PC stores

Answer 27

allows to use ATP-PC stores for longer
higher intensity
can complete multiple ballistic skills

Question 28

increased strength of tendons ligaments and bones

Answer 28

less likely to be injured
