Questions and Answers
- 1.
How many muscle fibre types are there?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
C. 3Explanation
There are three types of muscle fibers: slow-twitch (Type I), fast-twitch oxidative (Type IIa), and fast-twitch glycolytic (Type IIb). Each type of muscle fiber has different characteristics and functions. Slow-twitch fibers are used for endurance activities, while fast-twitch fibers are used for explosive movements. Therefore, the correct answer is 3.Rate this question:

What are the major differences between the fibre types?
- A.
Size, weight, and age
- B.
Speed, force, and endurance
- C.
Speed, flexibility, and composition
Correct Answer
B. Speed, force, and enduranceExplanation
The major differences between the fiber types are their speed, force, and endurance. Speed refers to how quickly the fibers can contract and generate force. Force is the amount of strength the fibers can produce. Endurance refers to the ability of the fibers to sustain contractions over a prolonged period of time. These differences in speed, force, and endurance contribute to variations in muscle performance and capabilities.Rate this question:

Which fibres are red and very resistant to fatigue?
- A.
Type 2a
- B.
Type 2b
- C.
Type 2c
- D.
Type 1
Correct Answer
D. Type 1Explanation
Type 1 fibres are red and very resistant to fatigue. These fibres are also known as slow-twitch fibres and are characterized by their ability to sustain long periods of low-intensity activity. They have a high concentration of mitochondria, which provide energy for aerobic activities. Type 1 fibres are important for endurance activities such as long-distance running or cycling. They are resistant to fatigue because they have a high capacity for oxidative metabolism, allowing them to produce energy efficiently over extended periods of time.Rate this question:

Which fibres are white, fatigue easily, and have a fast contraction velocity?
- A.
Type 2a
- B.
Type 2b
- C.
Type 2c
- D.
Type 1
Correct Answer
B. Type 2bExplanation
Type 2b fibers are white, fatigue easily, and have a fast contraction velocity. These fibers are also known as fast-twitch fibers and are responsible for generating quick and powerful muscle contractions. They are utilized during activities that require bursts of speed and strength, such as sprinting or weightlifting. Due to their fast contraction velocity, they tend to fatigue more quickly compared to other fiber types.Rate this question:

Which fibres contain medium amounts of myoglobin, mitochondria, and blood capillaries?
- A.
Type 2a
- B.
Type 2b
- C.
Type 2c
- D.
Type 1
Correct Answer
A. Type 2aExplanation
Type 2a fibers contain medium amounts of myoglobin, mitochondria, and blood capillaries. Myoglobin is a protein that binds oxygen in muscles, mitochondria are responsible for producing energy, and blood capillaries supply oxygen and nutrients to the muscles. Type 2a fibers are known as fast oxidative fibers and are able to generate energy quickly through aerobic metabolism. They have a higher capacity for endurance compared to Type 2b and Type 2c fibers, but not as much as Type 1 fibers.Rate this question:

A 400 metre runner would use ....................................... muscle fibres predominantly.
Correct Answer
Type 2a
type 2a
2a
Type 2A
type 2A
2AExplanation
A 400 metre runner would use type 2a muscle fibres predominantly. These muscle fibres are also known as fast-twitch oxidative-glycolytic fibers and are designed for high-intensity, short-duration activities. They have a high capacity for both aerobic and anaerobic metabolism, making them well-suited for sprinting events like the 400 metre race. These muscle fibres can generate a lot of force quickly but fatigue relatively quickly as well. Therefore, they are ideal for explosive bursts of speed required in sprinting.Rate this question:

A golfer on the driving range would use which muscle fibre predominantly?
- A.
Type 2a
- B.
Type 2b
- C.
Type 2c
- D.
Type 1
Correct Answer
D. Type 1Explanation
A golfer on the driving range would predominantly use Type 1 muscle fibers. Type 1 muscle fibers, also known as slow twitch fibers, are responsible for endurance activities and are resistant to fatigue. Golf swings require a sustained and repetitive motion, which relies on the endurance provided by Type 1 muscle fibers. These fibers are efficient at producing energy aerobically and are well-suited for activities that require prolonged muscle contractions, such as golf swings.Rate this question:

A Rugby player in a scrum would use which muscle fiber predominantly?
- A.
Type 2a
- B.
Type 2b
- C.
Type 2c
- D.
Type 1
Correct Answer
B. Type 2bExplanation
Type 2b muscle fibers, also known as fast-twitch muscle fibers, are predominantly used by Rugby players in a scrum. These muscle fibers are responsible for generating quick and powerful contractions, which are necessary for explosive movements such as pushing against opponents in a scrum. Type 2b fibers have a high capacity for anaerobic metabolism, allowing them to produce energy quickly without relying on oxygen. This makes them ideal for short bursts of intense activity, like the exertion required in a scrum.Rate this question:

Which of the following is another for Type II Fibers?
- A.
Medium twitch
- B.
Super twitch
- C.
Slow twitch
- D.
Fast twitch
Correct Answer
D. Fast twitchExplanation
Fast twitch fibers, also known as Type II fibers, are characterized by their ability to generate high levels of force and contract rapidly. These muscle fibers are responsible for producing powerful and explosive movements, such as sprinting or weightlifting. They fatigue quickly due to their reliance on anaerobic metabolism. In contrast, slow twitch fibers, or Type I fibers, are better suited for endurance activities as they contract slowly and are more resistant to fatigue. Therefore, the correct answer is "Fast twitch."Rate this question:

Approximately what percentage of Slow Twitch fibers does an average person has?
- A.
20%
- B.
50%
- C.
60%
- D.
80%
Correct Answer
C. 60%Explanation
An average person has approximately 60% of Slow Twitch fibers. Slow Twitch fibers are responsible for endurance activities and are resistant to fatigue. This means that an average person has a higher proportion of these fibers compared to Fast Twitch fibers, which are responsible for quick, explosive movements. Having a higher percentage of Slow Twitch fibers allows for better endurance and stamina in activities such as long-distance running or cycling.Rate this question:
