Question 1

Which of the following will not step up the fitness gains a person makes in performing an exercise?

Accepted Answer

Increasing vitamin intake before exercise does not directly enhance fitness gains. Fitness improvements are more closely related to exercise frequency, intensity, and duration.

Question 2

The endurance of a muscle is most accurately reflected in:

Accepted Answer

Muscle endurance is defined as the ability of a muscle to sustain repeated contractions or continue to perform over a period of time without fatigue.

Question 3

The heart rate a person must work at to achieve cardiovascular fitness is the:

Accepted Answer

The target heart rate is the heart rate a person must work at to achieve cardiovascular fitness. This is typically calculated as a percentage of the maximum heart rate.

Question 4

Stretching exercises are an important part of overall fitness, but they do not condition the:

Accepted Answer

Stretching exercises primarily focus on improving flexibility and range of motion in muscles, tendons, and ligaments, but they do not directly condition the cardiovascular system, which involves heart and lung endurance.

Question 5

To improve cardiovascular fitness, an the ACSM recommends that an individual exercise a continuous _____ at least five times a week.

Accepted Answer

The American College of Sports Medicine (ACSM) recommends 30-60 minutes of moderate-intensity exercise at least five times a week to improve cardiovascular fitness.

Question 6

To be fit, an individual needs to possess all of the following characteristics except :

Accepted Answer

Good genetics is not a characteristic that an individual needs to possess to be fit; fitness is achieved through lifestyle choices and physical activity.

Question 7

Muscles respond to the overload of exercise by gaining:

Accepted Answer

Muscles respond to the overload of exercise by increasing in size (hypertrophy) and strength as they adapt to handle the increased demands placed on them.

Question 8

The component of fitness that enables the heart muscle, blood vessels, and lungs to serve the body with maximum efficiency is:

Accepted Answer

Cardiovascular endurance refers to the ability of the heart, blood vessels, and lungs to deliver oxygen to the body efficiently during prolonged physical activity.

Question 9

All of the following describe an activity that will develop cardiovascular fitness except :

Accepted Answer

Cardiovascular fitness activities typically last longer than 10 minutes to effectively improve heart and lung endurance.

Question 10

Which proportion of calories from each energy nutrient is recommended for peak athletic performance?

Accepted Answer

For peak athletic performance, a higher proportion of carbohydrates is recommended to provide sufficient energy, with moderate protein for muscle repair and moderate fat for essential functions.

Question 11

The overall improvement of the cardiovascular system is known as:

Accepted Answer

Cardiovascular conditioning is the term used to describe the overall improvement of the cardiovascular system.

Question 12

The type of activity that relates to endurance and cardiovascular fitness is termed:

Accepted Answer

Aerobic activities are those that improve endurance and cardiovascular fitness by increasing the heart rate and breathing for an extended period.

Question 13

It is a mistake to think of _____ as one of the components of fitness.

Accepted Answer

Performance is an outcome or result of fitness, not a component. Components of fitness typically include strength, flexibility, and endurance.

Question 14

Which of the following is characteristic of the modern industrialized human, but not of the pre-agricultural hunter-gatherer?

Accepted Answer

Modern industrialized humans consume foods with refined sugar, which were not available to pre-agricultural hunter-gatherers.

Question 15

The proven physical and mental benefits of exercise include all of the following except :

Accepted Answer

Exercise generally decreases insulin resistance, improving insulin sensitivity, rather than increasing it.

Question 16

If a person wishes to develop larger muscles he should:

Accepted Answer

The answer of If a person wishes to develop larger...

Question 17

When a person stops using a muscle for a period of time due to injury, illness, or neglect, the muscle will:

Accepted Answer

When a muscle is not used for a period of time, it will atrophy, or waste away. This is because the muscle fibers are not being stimulated to contract, and they will begin to break down.

Question 18

Which of the following is not one of the components of fitness?

Accepted Answer

Lung volume is not typically considered a component of fitness; the main components are flexibility, muscle strength, muscle endurance, and cardiovascular endurance.

Question 19

Which of the following components of fitness has the most impact on long-term health?

Accepted Answer

Cardiovascular endurance is crucial for long-term health as it improves heart and lung function, reduces the risk of chronic diseases, and enhances overall longevity.

Question 20

With respect to the cardiovascular system, exercise leads to all of the following except :

Accepted Answer

Exercise typically increases total blood volume, not decreases it, as the body adapts to improve oxygen delivery and endurance.
