-
The capacity of a muscle to do work
-
Ability of contractile tissue to produce tension that results in a force
-
Work/time
-
Ability to continuely contract and resist
-
Exercise that involves a muscle contraction that is resisted
Correct Answer
A. Work/timeExplanation
The given correct answer states that power is defined as work divided by time. Power is a measure of how quickly work is done or how fast energy is transferred. It quantifies the rate at which work is performed or energy is expended. This definition aligns with the formula for power, which is the amount of work done divided by the time it takes to do that work. Therefore, the correct answer accurately describes power as the ratio of work to time.Rate this question:

What are the three key elements to muscle performance?
Correct Answer
endurance
strength
PowerExplanation
The three key elements to muscle performance are endurance, strength, and power. Endurance refers to the ability of muscles to sustain activity over a prolonged period of time. Strength refers to the maximum force that muscles can generate. Power is the combination of strength and speed, representing how quickly muscles can generate force. These three elements are crucial for optimal muscle performance in various activities and sports.Rate this question:

All of the following are true about resisive exercises except...
-
Can be applied both manually and mechanically
-
Any form of active exercise that is resisted
-
Includes anerobic exercises only
-
None of the above
-
All of the above
Correct Answer
A. Includes anerobic exercises onlyExplanation
The correct answer is "includes anaerobic exercises only." This statement is false because resistive exercises can include both aerobic and anaerobic exercises. Resistive exercises refer to any form of active exercise that is resisted, meaning that the muscles are working against a force or resistance. This resistance can be applied both manually, such as using weights or resistance bands, and mechanically, such as using machines or equipment. Therefore, the statement that resistive exercises include anaerobic exercises only is incorrect.Rate this question:

-
The capacity of a muscle to do work
-
Ability of contractile tissue to produce tension that results in a force
-
Work/time
-
Ability to continuely contract and resist
-
Exercise that involves a muscle contraction that is resisted
Correct Answer
A. Ability of contractile tissue to produce tension that results in a forceExplanation
Strength is the ability of contractile tissue to produce tension that results in a force. This means that strength refers to the capacity of muscles to generate force through the contraction of their fibers. It is not simply the ability to do work or the ability to contract and resist, but specifically the ability to produce tension that leads to a force. This definition encompasses the physiological aspect of strength and highlights the role of contractile tissue in generating force.Rate this question:

-
A and B
Correct Answer
A. Reduces or controls a force in a smooth, coordinated wayExplanation
Functional strength refers to the ability of muscles to work together efficiently and effectively during daily activities or sports. It involves the coordination and control of forces exerted by the muscles to perform tasks smoothly. The correct answer, "reduces or controls a force in a smooth, coordinated way," aligns with the concept of functional strength as it highlights the ability to manage and regulate forces in a coordinated manner, ensuring smooth and efficient movement.Rate this question:

Endurance is......
-
Low-intensity exercises over a long period of time
-
Aerobic power
-
Includes muscle endurance, the ability to repeatedly contract and resist force
-
All of the above
-
A and C only
Correct Answer
A. All of the aboveExplanation
The correct answer is "All of the above." This means that endurance includes low-intensity exercises over a long period of time, aerobic power, and muscle endurance. Low-intensity exercises over a long period of time refer to activities that are sustained for a prolonged duration, such as jogging or cycling. Aerobic power is the ability of the body to take in, transport, and utilize oxygen during exercise. Muscle endurance refers to the capacity of muscles to repeatedly contract and resist force. Therefore, all of these options are correct explanations of endurance.Rate this question:

The overload principle states
-
Adaptation of wolff's law
-
Is specific to enviornment
-
A load needs to exceed capacity in order to improve muscle strength or endurance
-
Too many reps or too much weight will result in muscle fatigue and a general lack to obtaining goals
-
States a constant resistance will result in increased strength overtime
Correct Answer
A. A load needs to exceed capacity in order to improve muscle strength or enduranceExplanation
The overload principle states that in order to improve muscle strength or endurance, a load (such as weight or resistance) needs to exceed the capacity of the muscles. This means that the muscles need to be challenged beyond what they are used to in order to stimulate adaptation and improvement. If the load is too light or does not exceed the capacity of the muscles, there will be no significant improvement in strength or endurance.Rate this question:

In order to increase strength of a muscle you should....
-
Increase sets or reps
-
Increase resistance
-
Increase frequency
-
Any of the above would result in increased strength
Correct Answer
A. Increase resistanceExplanation
Increasing resistance is the correct answer because it is a fundamental principle of strength training. When you increase the resistance or load placed on a muscle during exercise, it creates a greater demand on the muscle fibers, leading to adaptations that increase strength. This can be achieved by using heavier weights, resistance bands, or machines with adjustable resistance. Increasing sets or reps and frequency can also contribute to muscle growth and endurance, but specifically increasing resistance is the most effective way to increase strength.Rate this question:

SAID principle includes all of the following except
-
Adaptation of Wolff's law
-
Specificity
-
Transfer of training
-
Strokes
-
All of the above are included in SAID
Correct Answer
A. All of the above are included in SAIDExplanation
The SAID principle (Specific Adaptation to Imposed Demands) is a principle in exercise science that states that the body will specifically adapt to the demands placed upon it. This means that the body will adapt and improve in response to the specific type of training or exercise it is subjected to. The options given in the question, namely adaptation of Wolff's law, specificity, transfer of training, and strokes, are all included in the SAID principle. Therefore, the correct answer is that all of the above options are included in SAID.Rate this question:

Detraining will occur after how long of inactivity?
-
2 days
-
1 week
-
3 weeks
-
1 month
-
2 months
Correct Answer
A. 1 weekExplanation
Detraining is the process in which the body loses the benefits of physical training due to inactivity. After about a week of inactivity, the body starts to experience detraining effects such as decreased muscle strength, endurance, and cardiovascular fitness. This occurs because the body adapts to the demands of exercise and when those demands are not met, the body gradually reverts back to its pre-training state. Therefore, the correct answer is 1 week.Rate this question:

All of the following are factors that influence tension except
-
Location of muscle
-
Cross section and size
-
Speed of muscle contraction
-
Recruitment of motor fibers
-
Fiber type distribution
Correct Answer
A. Location of muscleExplanation
The location of the muscle does not directly influence tension. Factors such as cross section and size, speed of muscle contraction, recruitment of motor fibers, and fiber type distribution can all affect tension production in a muscle. However, the specific location of the muscle does not play a direct role in determining the amount of tension it can generate.Rate this question:

All are signs of local fatigue except
-
Shaking
-
Substitution
-
Dizziness
-
Jerking
-
Cramping
Correct Answer
A. DizzinessExplanation
Local fatigue refers to fatigue or weakness in a specific muscle or group of muscles. Shaking, substitution, jerking, and cramping are all signs of local fatigue because they indicate muscle weakness or instability. However, dizziness is not typically associated with local fatigue. Dizziness is a sensation of lightheadedness or unsteadiness, which may be caused by various factors such as inner ear problems, low blood sugar, or dehydration. Therefore, dizziness is not considered a sign of local fatigue.Rate this question:

Correct Answer
A. Increased potassium levelsExplanation
Generalized fatigue refers to fatigue that affects the entire body and is not specific to any particular organ or system. It is commonly associated with conditions such as chronic fatigue syndrome or fibromyalgia. The other options mentioned in the question, such as decreased blood sugar levels and decreased glycogen stores, are known to contribute to fatigue. However, increased potassium levels do not typically cause generalized fatigue. Therefore, the correct answer is increased potassium levels.Rate this question:

Changes that occur in recovery include all except....
-
Replenished energy stores
-
Can occur intrasession or intersession
-
Lactic acid removal in approx 1 hour
-
Oxygen stores replenished
-
Glycogen stores restored within 1 hour
Correct Answer
A. Glycogen stores restored within 1 hourExplanation
During the recovery phase, several changes occur in the body to restore its normal state after exercise. Replenishing energy stores is one such change, as the body needs to replenish the depleted ATP and creatine phosphate stores. Recovery can occur both within a single session (intrasession) and between sessions (intersession). Lactic acid removal typically takes around 1 hour as it is converted into less harmful substances. Oxygen stores are replenished during recovery to restore normal oxygen levels in the body. However, glycogen stores, which are the stored form of glucose in the muscles and liver, are not fully restored within 1 hour of recovery.Rate this question:

In early adolescent muscle mass consist of....
-
10% BW
-
25% BW
-
40% BW
-
60% BW
-
75% BW
Correct Answer
A. 25% BWExplanation
During early adolescence, muscle mass typically makes up about 25% of a person's body weight. This is because during this stage of development, individuals experience significant growth spurts and their bodies undergo various changes. These changes include the development of skeletal muscles, which contribute to the overall muscle mass. As a result, muscle mass increases and accounts for approximately 25% of their body weight during this period.Rate this question:

Concentric contraction .....
-
Shortening of a muscles
-
Rate control contraction
-
Lengthening of a muscle
-
Involves no muscle movement
Correct Answer
A. Shortening of a musclesExplanation
Concentric contraction refers to the shortening of a muscle. This occurs when the muscle generates force and contracts, causing the muscle fibers to pull together and decrease in length. During concentric contractions, the muscle is actively contracting and producing movement. This is in contrast to eccentric contractions, where the muscle lengthens while still generating force, and isometric contractions, where the muscle remains at a constant length without any movement.Rate this question:

-
Muscle setting
-
Stabilization
-
Concentric
-
Eccentric
-
Multi-angle
Correct Answer(s)
A. Muscle setting
A. Stabilization
A. Multi-angleExplanation
The correct answer includes three types of isometric exercises: muscle setting, stabilization, and multi-angle. Muscle setting exercises involve contracting and relaxing specific muscles to improve strength and control. Stabilization exercises focus on maintaining balance and stability in the body. Multi-angle exercises involve working muscles at different angles to target different muscle fibers and improve overall strength and flexibility. These three types of exercises offer a comprehensive approach to building strength, stability, and muscle control.Rate this question:
