Muscle Contraction During Exercise Of Differing intensity and during recovery

Question 1

What are the three muscle fibre types?

Answer 1

Slow oxidative
Fast oxidative glycolitic
Fast glycolitic

Question 2

What protein carries the oxygen from the blood to the haemoglobin?

Answer 2

Myoglobin

Question 3

Explain the physical properties of slow oxidative muscle fibre types.

Answer 3

Rich in mitochondria myoglobin and capillaries produces a small amount of force over long period of time.

Question 4

Explain the functional properties of slow oxidative and muscle fibre types

Answer 4

They work aerobically producing a small amount of force resisting fatigue for a long period of time.

Question 5

What are the functional properties of fast oxidative glycolitic muscle fibres?

Answer 5

They produce a large amount of force quickly whilst also being able to resist fatigue.

Question 6

What are the physical properties of fast glycolitic muscle fibres?

Answer 6

Which in phosphocreatine which produces a maximal force over a short period of time

Question 7

What are the functional properties of fast glycolitic muscle fibres?

Answer 7

Work anaerobically with large stores of phosphocreatine producing large amounts of force but fatiguing– high intensity, short duration.

Question 8

What are the structural characteristics of slow oxidative muscle fibres?

Answer 8

Small neuron size and low phosphocreatine store.

Question 9

What are the structural characteristics of fast oxidative glycolitic muscle fibres?

Answer 9

Large neuron size moderate myoglobin content and high phosphocreatine store.

Question 10

What are the structural characteristics of fast glycolitic muscle fibre types?

Answer 10

Large neon size and high phosphocreatine store

Question 11

What are the functional characteristics of slow oxidative muscle fibres?

Answer 11

Slow speed of contraction and higher aerobic capacity.

Question 12

What are the functional characteristics of fast oxidative glycolitic muscle fibres?

Answer 12

Fast speed of contraction, moderate aerobic capacity and moderate anaerobic capacity

Question 13

What are the functional characteristics of fast glycolitic muscle fibres?

Answer 13

Fast speed of contraction and high anaerobic capacity and low aerobic capacity.

Question 14

What type of athletes are likely to have a highest percentage of slow oxidative muscle fibres?

Answer 14

Endurance athletes, e.g. marathon triathlon cross-country skiing

Question 15

What type of athletes are likely to have a highest percentage of fast oxidative glycolitic muscle fibres?

Answer 15

High intensity athletes, e.g. 800 to 1500 m.

Question 16

What type of athletes are likely to have a highest percentage of fast glycolitic muscle fibres?

Answer 16

Explosive athletes, e.g. 60 to 100 meter sprint javelin long jump.
