Muscle Fibre Types

Question 1

What are the three fibre types?

Answer 1

Slow oxidative
Fast oxidative glycolytic
Fast glycolytic

Question 2

What are the functional characteristics of slow oxidative muscle fibres?

Answer 2

Aerobic
Slow rate of fatigue
Slow speed of contraction
Little force of contraction
Relatively slow recovery rate

Question 3

What is the speed of contraction for fast oxidative glycolic?

Answer 3

High to medium speed of contraction
High to medium force of contraction
Medium rate of fatigue
Both aerobic and anaerobic
Medium recovery rate

Question 4

What are the functional characteristics of fast glycolic muscle fibres?

Answer 4

Fast speed of contraction
Large force of contraction
Quick rate of fatigue
Anaerobic.
Fast recovery rate

Question 5

What is periodisation?

Answer 5

Organisation is the division of a training year into smaller and more manageable intervals with goal setting.

Question 6

What is a macro cycle?

Answer 6

Typically includes all 52 weeks of your annual training plan involves a long-term performance goal. This cycle includes the preparation competition and recovery phases of your plan.

Question 7

What are miso cycles?

Answer 7

Me so cycles are typically 3 to 6 weeks in length and have specifically targeted outcomes. These involved developing a particular component of fitness such as power strength or endurance.

Question 8

What are miso cycles?

Answer 8

Me so cycles are typically 3 to 6 weeks in length and have specifically targeted outcomes. These involved developing a particular component of fitness such as power strength or endurance.

Question 9

What is a micro cycle?

Answer 9

The shortest training cycle typically a week training block a micro cycle provides the information and athlete needs to complete their training for that week. Micro cycles may be similar from each weeks.

Question 10

What is meant by the preparation period?

Answer 10

The length of preparation period is dependent on the sport however it typically occurs 8 to 12 weeks before the start of the competition. They tend to use miso cycles to work on general conditioning improving strength, speed and flexibility.

Question 11

What is meant by the competition period?

Answer 11

Performance will focus on maintaining their fitness levels throughout their competitive season.

Question 12

What is the transition period?

Answer 12

Also known as the off-season period it allows an athlete to recover physically and mentally from a demanding season.

Question 13

What is general conditioning?

Answer 13

Improving cardiovascular, fitness, strength, power and flexibility it has a high training frequency and bullying

Question 14

What is specific conditioning?

Answer 14

Specific areas of fitness are targeted and improved

Question 15

When will the different fibre types be recruited?

Answer 15

Low intensity only slow oxidative fibres are used
At higher intensities fast oxidative fibres will be recruited
At highest intensity fast glycolytic fibres will be recruited.

Question 16

Give one example of each slow oxidative fibre fast alternative fibre and fast glycolic fibres?

Answer 16

Slow oxidative: aerobic and a study pace marathon
Fast oxidative fibres: increased in paste during a marathon
Fast oxidative glycolic: sprinting during hurdle race/marathon finish

Question 17

Why are slow oxidative fires always used first?

Answer 17

Recovery quickly able for a recruitment after just 90 seconds.

Question 18

Why are fast glycolytic fibres recruited last?

Answer 18

Max effort needed quickly ready for a long recovery time

Question 19

What are the characteristics of slow oxidative muscle fibres?

Answer 19

For quick recovery during training between heats for aerobic activity

Question 20

What are the characteristics of fast oxidative fibre?

Answer 20

Maintain speed at the end of the race for higher intensity training sessions.

Question 21

What are the characteristics of fast oxidative glycolic muscle fibres?

Answer 21

Hard needs fast glycolic fibres for speed power and explosive to clear the hurdles

Question 22

What are the slow oxidative structural characteristics?

Answer 22

Small neurons and a few fibres
Lots of mitochondria
Hi mioglobin content
High capillary density

Question 23

What are the structural characteristics of fast oxidative muscle fibres?

Answer 23

Large neurons, many fibres
Large stores of phosphocreatine
High capillary density
Moderate amount of mitochondria
Moderate myoglobin content

Question 24

What are the structural characteristics of fast glycolytic muscle fibres?

Answer 24

Large neurons many fibre per neuron
High stores of phosphate creatine
