Which one of the following is the correct statement about muscle action and antagonistic pairs?
- A.
When a muscle contracts and pushes a bone, for example, the biceps and triceps
- B.
Movement is brought about through antagonistic pairs, for example, the pectorals and abdominals
- C.
Muscles are arranged in pairs, for example, the hamstring and quadriceps
- D.
When one muscle contracts the other relaxes to bring about movement, for example, the trapezius and latissimus dorsi
Correct Answer
D. When one muscle contracts the other relaxes to bring about movement, for example, the trapezius and latissimus dorsiExplanation
This statement correctly explains the concept of muscle action and antagonistic pairs. When one muscle contracts, the other muscle in the pair relaxes, allowing for movement to occur. The example given, the trapezius and latissimus dorsi, are muscles that work together in this way.Rate this question:

Which one of the following statements correctly explains the term isometric?
- A.
An isometric muscle contraction does not result in movement
- B.
A gymnast running across the floor towards the vault is using isometric muscle contraction
- C.
A swimmer using her leg muscles to 'explode' from the blocks when the whistle blows uses isometric contractions
- D.
An isometric muscle contraction is less strenuous than an isotonic contraction. This means the muscle can continue to work for longer.
Correct Answer
A. An isometric muscle contraction does not result in movementExplanation
An isometric muscle contraction refers to a type of muscle contraction in which there is no visible movement or change in the length of the muscle. During an isometric contraction, the muscle generates tension but remains in a fixed position. This type of contraction is commonly used in exercises such as planks or wall sits, where the muscles are engaged but do not produce any movement in the joints. Isometric contractions can be beneficial for building strength and stability in specific muscle groups.Rate this question:

Which muscle is contracting to allow a cyclist to flex his leg at the knee?
- A.
Trapezius
- B.
Hamstrings
- C.
Gastrocnemium
- D.
Quadriceps
Correct Answer
B. HamstringsExplanation
The hamstrings are responsible for flexing the leg at the knee joint. When a cyclist wants to bend their leg while pedaling, the hamstrings contract, allowing the leg to flex at the knee. The trapezius muscle is located in the upper back and is responsible for movements such as shrugging the shoulders and rotating the shoulder blades. The gastrocnemius muscle is located in the calf and is responsible for plantar flexion of the foot. The quadriceps muscle group is located in the front of the thigh and is responsible for extending the leg at the knee joint.Rate this question:

Which of the following muscles abduct the upper arm at the shoulder as a swimmer moves his arms for a dive from the starting blocks?
- A.
Deltoids
- B.
Trapezius
- C.
Pectorals
- D.
Biceps
Correct Answer
A. DeltoidsExplanation
The deltoids are the correct answer because they are responsible for the abduction of the upper arm at the shoulder. During a dive from the starting blocks, the swimmer needs to move their arms away from the midline of the body, which is the action of abduction. The trapezius, pectorals, and biceps are not primarily involved in this specific movement.Rate this question:

The correct statement in relation to muscle tone is:
- A.
Muscle contraction that is controlled conciously
- B.
The reflex contraction of involuntary muscles
- C.
Muscle definition in an elite performer
- D.
State of slight tension in voluntary muscles
Correct Answer
D. State of slight tension in voluntary musclesExplanation
The correct answer is "State of slight tension in voluntary muscles." Muscle tone refers to the continuous and partial contraction of voluntary muscles, even when at rest. This slight tension helps maintain posture and stability. It is different from muscle contraction that is controlled consciously, as that refers to intentional movements. Reflex contraction of involuntary muscles is not related to muscle tone, and muscle definition in an elite performer is not a direct description of muscle tone.Rate this question:

Which one of these muscles are located at the shoulder?
- A.
Deltoids
- B.
Pectorals
- C.
Trapezius
- D.
Abdominals
Correct Answer
A. DeltoidsExplanation
The deltoids are the muscles located at the shoulder. They are triangular in shape and cover the shoulder joint. The deltoids are responsible for various movements of the arm, including lifting, rotating, and extending the arm. They are commonly targeted in shoulder exercises to strengthen and tone the shoulder muscles. The pectorals are chest muscles, the trapezius is a large muscle that extends from the back of the neck to the upper back, and the abdominals are the muscles in the abdominal region.Rate this question:

The Latissimus Dorsi is located on the side of the back.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The Latissimus Dorsi is actually a large, flat muscle that is located on the middle and lower back. It is broadest at its origin and tapers as it extends towards its insertion points. This muscle covers a significant portion of the back and extends from the lower part of the thoracic spine (T7-T12) to the lumbar vertebrae, as well as reaching up to the iliac crest of the pelvis. Its primary actions include extension, adduction, and medial rotation of the shoulder joint.Rate this question:

Which one of the following is not a long term effect of training on the Muscular System?
- A.
Muscular Atrophy
- B.
Muscular Hypertrophy
- C.
Increased myoglobin Stores
- D.
Stronger Tendons and Ligaments
Correct Answer
A. Muscular AtrophyExplanation
Muscular atrophy is the correct answer because it is not a long-term effect of training on the muscular system. Muscular atrophy refers to the loss of muscle mass and strength, which can occur due to various reasons such as disuse, injury, or certain medical conditions. However, training typically leads to muscular hypertrophy, which is the growth and increase in size of muscle fibers. Increased myoglobin stores and stronger tendons and ligaments are also long-term effects of training on the muscular system, as they help improve oxygen delivery to muscles and enhance overall strength and stability.Rate this question:

Which one of the following statements identifies the main role of Protein in the diet?
- A.
Helps to repair muscle when injured
- B.
Provides a muscle with energy
- C.
Prevents muscle fatigue during exercsie
- D.
Develops Atrophy in the muscles asa result of exercsie
Correct Answer
A. Helps to repair muscle when injuredExplanation
Protein plays a crucial role in repairing muscles when they are injured. When muscles undergo stress or damage, protein helps in the process of repairing and rebuilding the damaged muscle fibers. It provides the necessary building blocks for muscle tissue repair and promotes the synthesis of new muscle proteins. Protein also aids in reducing inflammation and promoting recovery after exercise or injury.Rate this question:

Which one of the following is not a short term effect of exercise on the Muscular System?
- A.
Increased Muscle Tempreture
- B.
Increased production of Carbon Dioxide
- C.
Increased lactic acid production
- D.
Increased strength of muscles
Correct Answer
D. Increased strength of musclesExplanation
Increased strength of muscles is not a short term effect of exercise on the Muscular System. While exercise can lead to increased strength of muscles over time with consistent and regular training, it is not an immediate or short term effect. Short term effects of exercise on the Muscular System include increased muscle temperature, increased production of carbon dioxide, and increased lactic acid production. These effects occur during and immediately after exercise, while increased muscle strength is a long term adaptation that happens with continued training and progressive overload.Rate this question:

The Rugby Scrum is an example of an ISOMETRIC MUSCLE CONTRACTION.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because an isometric muscle contraction occurs when the muscle generates tension without changing its length. In a rugby scrum, the players push against each other, creating tension in their muscles without any significant movement. Therefore, the rugby scrum is an example of an isometric muscle contraction.Rate this question:
