Question 1

​Pushing muscles hard against an immovable object is an example of _____ exercise.
A) ​aerobic
B) ​anaerobic
C) ​isokinetic
D) ​isometric

Accepted Answer

Pushing muscles hard against an immovable object is an example of isometric exercise, where the muscles are contracted without movement.

Question 2

​Activities such as jogging, cross-country skiing, or swimming are classified as _________ exercise and activities such as short-distance running or softball are classified as _________ exercise.
A) ​anaerobic; aerobic
B) ​isometric; aerobic
C) ​aerobic; anaerobic
D) ​aerobic; isometric

Accepted Answer

Aerobic exercise is characterized by low to moderate intensity and longer duration, during which the body utilizes oxygen to produce energy. Examples of aerobic exercise are jogging, cross-country skiing, or swimming. Anaerobic exercise consists of high-intensity, short-duration activities such as weightlifting, sprinting, or softball. Therefore, the best option is C, which classifies jogging, cross-country skiing, or swimming as aerobic exercise and short-distance running or softball as anaerobic exercise.

Question 3

​Aerobic fitness tends to
A) ​increase muscle strength.
B) ​decrease resting heart rate.
C) ​decrease resting blood pressure.
D) ​decrease b and c, not increase A

Accepted Answer

Aerobic fitness primarily improves cardiovascular efficiency, which leads to a decrease in resting heart rate and resting blood pressure, rather than increasing muscle strength, which is more related to anaerobic exercises.

Question 4

​People who have high aerobic fitness, compared with those who have low aerobic fitness,
A) ​have about the same rate of all-cause mortality.
B) ​have a higher rate of all-cause mortality.
C) ​have a lower death rate from heart disease.
D) ​have a higher death rate from heart disease.

Accepted Answer

Numerous studies have consistently shown that individuals with high aerobic fitness have a lower death rate from heart disease compared to those with low aerobic fitness. However, the rate of all-cause mortality is similar between the two groups. Therefore, choice C is the best answer.

Question 5

What type of exercise requires specialized equipment to promote muscle strength and muscle endurance?
A) Isokinetic
B) Isotonic
C) Isometric
D) Anaerobic

Accepted Answer

Isokinetic exercise specifically requires specialized equipment such as a machine that controls the speed and resistance of the movement. This type of exercise is designed to promote both muscle strength and endurance by providing resistance throughout the entire range of motion at a constant speed. Isotonic and isometric exercises do not necessarily require specialized equipment, and anaerobic exercise focuses more on high-intensity bursts of activity rather than muscle endurance.

Question 6

Isometric exercise is designed to
A) increase cardiovascular fitness.
B) increase lung capacity.
C) increase muscle endurance.
D) increase muscle strength.

Accepted Answer

Isometric exercise involves holding a static position, which leads to an increase in muscle strength. It does not typically improve cardiovascular fitness, lung capacity, or muscle endurance.

Question 7

​Regarding diet, exercise, and weight loss, which statement is true?
A) ​Exercise alone can produce weight loss.
B) ​Dieters lose weight, but they also retain lean muscle tissue.
C) ​Exercisers lose weight, but they lose mostly lean muscle tissue.
D) ​Both a and b are true.

Accepted Answer

Exercise alone can produce weight loss, although it is often more effective when combined with dietary changes.

Question 8

​Willa is a track star in college. Her specialties are the 100-meter dash and the 200-meter dash. The type of exercise she is receiving during these races is mostly
A) ​isometric.
B) ​isotonic.
C) ​isokinetic.
D) ​anaerobic.

Accepted Answer

The 100-meter dash and the 200-meter dash are short-distance races that require high-intensity bursts of speed. This type of exercise is anaerobic, which means it is fueled by stored energy in the muscles rather than oxygen. Isometric exercise involves muscle contractions without movement, isotonic exercise involves movement against resistance, and isokinetic exercise involves movement at a constant speed.

Question 9

​The type of exercise that requires the LEAST amount of physical activity is
A) ​isometric.
B) ​isotonic.
C) ​isokinetic.
D) ​anaerobic.

Accepted Answer

Isometric exercise involves holding a muscle contraction without movement, so it requires very little physical activity compared to other types of exercise.

Question 10

​Aerobic fitness gained through vigorous physical activity
A) ​decreases the risk of heart attack.
B) ​decreases cardiorespiratory fitness.
C) ​increases resting heart rate.
D) ​decreases exercise-related injuries.

Accepted Answer

Aerobic fitness gained through vigorous physical activity decreases the risk of heart attack by strengthening the heart and improving blood circulation.

Question 11

What distinguishes anaerobic exercise from aerobic exercise?
A) The amount of muscle contraction
B) The amount of oxygen consumption
C) The degree of joint rotation
D) The amount of body movement

Accepted Answer

Anaerobic exercise does not rely on oxygen consumption to produce energy, while aerobic exercise does.

Question 12

​Organic fitness is determined by
A) ​inherent body characteristics.
B) ​taking the exercise stress test.
C) ​regular and strenuous exercise.
D) ​the degree of muscular strength.

Accepted Answer

Organic fitness refers to the fitness determined by inherent body characteristics, such as genetics and physiological factors, rather than external factors like exercise or training.

Question 13

​What is/are the important features of aerobic exercise?
A) ​Intensity
B) ​Duration
C) ​Frequency
D) (a) and (b)

Accepted Answer

The important features of aerobic exercise are intensity and duration. Frequency is also an important factor, but the most essential features are intensity and duration. Therefore, the best choice is D) (a) and (b).

Question 14

Brooke is bedridden after an auto accident. What exercise would help her maintain muscular strength in her arms with a minimum of movement?
A) Isometric
B) Isotonic
C) Aerobic
D) Isokinetic

Accepted Answer

Isometric exercises involve contracting and holding a muscle without any movement. This will allow Brooke to maintain muscular strength in her arms with minimal movement, making it a good choice for her current situation. Isotonic exercises involve movement and may not be feasible for Brooke, while aerobic and isokinetic exercises are not specific to maintaining muscular strength in the arms.

Question 15

​Cynthia injured her knee while downhill skiing and is currently in a rehab program to help regain strength and flexibility in her knee. She is most likely doing ________ exercise.
A) ​anaerobic
B) ​aerobic
C) ​isometric
D) ​isokinetic

Accepted Answer

Isokinetic exercises are often used in rehabilitation programs to help regain strength and flexibility because they can be controlled for speed and resistance, making them ideal for targeting specific muscles or joints, such as the knee, without overexerting them.

Question 16

​If the goal of your exercise program is to improve your cardiovascular health, you should most likely engage in ________ exercise.
A) ​anaerobic
B) ​aerobic
C) ​isometric
D) ​isokinetic

Accepted Answer

Aerobic exercise, such as jogging, swimming, or cycling, is most effective in improving cardiovascular health as it increases heart rate and respiration, leading to improved circulation and overall cardiovascular function. Anaerobic, isometric, and isokinetic exercise may improve muscle strength and endurance but do not have as significant an impact on cardiovascular health.

Question 17

​Bess has moderate weight and good organic fitness. If she begins an aerobic exercise program, she will probably
A) ​lose 10 to 15 pounds.
B) ​gain 10 to 15 pounds.
C) ​increase lean body weight and decrease body fat.
D) ​decrease lean body weight and increase body fat.

Accepted Answer

Aerobic exercise helps to increase lean body weight and decrease body fat. It is unlikely that Bess will gain or lose a significant amount of weight, as her weight is already moderate. Therefore, choice C is the best option.

Question 18

-​Isotonic exercise is designed to
A) ​increase cardiovascular fitness.
B) ​increase muscle endurance.
C) ​increase muscle strength.
D) ​increase both (b) and (c).

Accepted Answer

Isotonic exercise involves the use of weights or resistance to increase muscle strength and endurance. As a result, it can improve both muscle endurance and muscle strength. While isotonic exercise may also have some cardiovascular benefits, the primary goal is to target the muscles. Therefore, choices (a) and (b) are not the best options as they only address one aspect of isotonic exercise, while (d) encompasses both benefits.

Question 19

​Tatum was considered a natural athlete in college, but she has not been active since she left college 10 years ago. Presently, the type of fitness that Tatum probably has is
A) ​dynamic fitness.
B) ​organic fitness.
C) ​both dynamic and organic fitness.
D) ​neither dynamic nor organic fitness.

Accepted Answer

Organic fitness refers to the natural physical abilities and genetic potential one possesses, which Tatum likely still has despite not being active.

Question 20

​The type of fitness known as flexibility is best increased by
A) ​weight lifting.
B) ​stretching.
C) ​jogging.
D) ​short, fast runs.

Accepted Answer

Flexibility is best increased by stretching, as it helps to lengthen and increase the range of motion of muscles and joints. Weight lifting and short, fast runs may help with strength and endurance, but will not necessarily improve flexibility. Jogging can help with cardiovascular health, but also does not specifically target flexibility.
