Question 1

What distinguishes anaerobic exercise from aerobic exercise?

Accepted Answer

Anaerobic exercise is characterized by short bursts of high-intensity activity that do not rely on oxygen for energy production, whereas aerobic exercise involves sustained, low to moderate intensity activity that does require oxygen for energy production. Therefore, the key distinguishing factor between the two is the amount of oxygen consumption.

Question 2

Pushing muscles hard against an immovable object is an example of _____ exercise.

Accepted Answer

Pushing muscles hard against an immovable object is an example of isometric exercise, as the muscles are contracting without any movement or change in length.

Question 3

Brooke is bedridden after an auto accident.What exercise would help her maintain muscular strength in her arms with a minimum of movement?

Accepted Answer

Isometric exercises involve holding a muscle in a static position without any movement. This can be done by pushing against a solid object or by simply tightening and holding the muscle. Isometric exercises can help maintain muscular strength in the arms without requiring much movement, making them a great choice for someone who is bedridden.

Question 4

Lynn would like to quit smoking,but she is concerned that she will gain weight.What advice would you give her?

Accepted Answer

Quitting smoking is one of the best things that Lynn can do for her health, and gaining some weight is a small price to pay. It is important for her to eat regularly and choose healthy, whole foods, rather than turning to junk food to replace the nicotine cravings. Starting a physical activity program will not only help mitigate weight gain, but also improve her overall health and well-being. A low calorie diet is not recommended because it can be difficult to sustain, and Lynn may not be getting all the nutrients she needs to support her body during this transition.

Question 5

Organic fitness is determined by

Accepted Answer

Organic fitness refers to the inherent capabilities of an individual's body, including factors such as genetics, body composition, and cardiovascular health. Regular exercise can improve and maintain organic fitness, but it is not the sole determinant. The exercise stress test and muscle strength also contribute to overall fitness, but neither is as comprehensive as considering the inherent characteristics of the body.

Question 6

What type of exercise requires specialized equipment to promote muscle strength and muscle endurance?

Accepted Answer

Isokinetic exercises require specialized equipment, such as machines that provide resistance throughout the entire range of motion, to promote both muscle strength and endurance.

Question 7

Bess has moderate weight and good organic fitness.If she begins an aerobic exercise program,she will probably

Accepted Answer

Aerobic exercise programs typically increase lean body weight and decrease body fat, especially in individuals who have moderate weight and good organic fitness like Bess. Weight loss or gain of 10 to 15 pounds is not necessarily a guarantee and would depend on additional factors such as diet and intensity of exercise.

Question 8

Isometric exercise is designed to

Accepted Answer

Isometric exercises involve contracting muscles without movement, which helps to build muscle strength.

Question 9

With regard to diet,exercise,and weight loss,which statement is true?

Accepted Answer

The answer of With regard to diet,exercise,and weight loss,which statement...

Question 10

If the goal of your exercise program is to improve your cardiovascular health,you should most likely engage in ________ exercise.

Accepted Answer

Aerobic exercise is the best choice for improving cardiovascular health as it involves sustained, rhythmic movements that increase heart rate and breathing rate, effectively strengthening the heart and lungs over time. Anaerobic, isometric, and isokinetic exercise do not provide the same cardiovascular benefits.

Question 11

Aerobic fitness tends to

Accepted Answer

Aerobic fitness is associated with both a decrease in resting heart rate and resting blood pressure. However, it is not typically associated with an increase in muscle strength.

Question 12

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.

Accepted Answer

Isokinetic exercise involves resistance through the full range of motion and is often used in rehab programs to improve muscle strength and joint flexibility. This type of exercise is best suited for individuals who are recovering from injury or surgery. Anaerobic exercise is high-intensity activity that primarily utilizes glucose for energy, such as weightlifting or sprinting. Aerobic exercise is moderate-intensity activity that utilizes oxygen for energy, such as brisk walking or cycling. Isometric exercise involves static contraction of a specific muscle group without movement, such as holding a plank pose.

Question 13

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

Accepted Answer

The answer of Tatum was considered a natural athlete in...

Question 14

Aerobic fitness gained through vigorous physical activity

Accepted Answer

Aerobic fitness gained through vigorous physical activity decreases the risk of heart attack.

Question 15

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

Accepted Answer

The type of exercise Willa receives during the 100-meter and 200-meter dashes is mostly anaerobic. These races are short bursts of intense activity that rely on the body's stored energy, rather than oxygen, for fuel.

Question 16

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.

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 17

The type of exercise that requires the LEAST amount of physical activity is

Accepted Answer

Isometric exercises involve holding a static muscle contraction without any movement of the joints, so it requires the least amount of physical activity.

Question 18

People who have high aerobic fitness,compared with those who have low aerobic fitness,

Accepted Answer

People with high aerobic fitness have a lower death rate from heart disease compared to those with low aerobic fitness. However, their rate of all-cause mortality may not necessarily differ significantly. Studies have shown that aerobic fitness is a strong predictor of cardiovascular health and reducing the risk of heart disease.

Question 19

Isotonic exercise is designed to

Accepted Answer

Isotonic exercise involves using resistance to move a weight through a range of motion, which helps to increase muscle strength. Option A is incorrect because cardio exercises like running and cycling are better for increasing cardiovascular fitness. Option B is incorrect because breathing exercises are better for increasing lung capacity, and option C is incorrect because anaerobic exercises like high-intensity interval training (HIIT) or resistance training with low repetition and high load are better for increasing muscle endurance.

Question 20

The type of fitness known as flexibility is best increased by

Accepted Answer

Flexibility is best increased by stretching, as it helps to lengthen and loosen muscles, tendons, and ligaments. Weight lifting and short, fast runs primarily focus on building strength and endurance, while jogging can improve cardiovascular fitness but does not specifically target flexibility.
