Question 1

What duration is used to define a "bout" of physical activity in the national physical activity guidelines?

Accepted Answer

The national physical activity guidelines define a bout of physical activity as at least 10 minutes in duration.

Question 2

How many MET minutes would a person achieve if they ran at 6 METS for 20 minutes?

Accepted Answer

MET minutes are calculated by multiplying the MET value by the number of minutes. So, 6 METs x 20 minutes = 120 MET minutes.

Question 3

Mowing the lawn is best characterized as a(n)________ activity.

Accepted Answer

Mowing the lawn is typically considered a moderate physical activity, as it requires a steady amount of effort and increases the heart rate, but does not usually reach the intensity of vigorous activities.

Question 4

Which of the following satisfies the minimum U.S Physical Activity Guidelines developed by the Department of Health and Human Services (DHHS)?

Accepted Answer

The minimum U.S Physical Activity Guidelines developed by DHHS recommends either 75 minutes of vigorous activity or 150 minutes of moderate activity per week. Therefore, option B is the best choice as it satisfies the minimum recommendation.

Question 5

Brisk walking would most likely be at what MET level?

Accepted Answer

Brisk walking would most likely be at a MET level of 4, which is moderate-intensity physical activity. This level of physical activity has been shown to have numerous health benefits, including reducing the risk of chronic diseases such as cardiovascular disease, diabetes, and some cancers. Additionally, brisk walking is a low-impact and accessible form of exercise that can be easily incorporated into one's daily routine.

Question 6

Which is true of moderate activity?

Accepted Answer

Moderate activity can be achieved with brisk walks throughout the day. It does not require special equipment or specific skills, and it can be done in multiple bouts rather than continuous ones.

Question 7

What is the approximate caloric equivalent of 1 MET?

Accepted Answer

1 MET is equal to burning 100 calories per kilogram of body weight per hour.

Question 8

Current physical activity guidelines from the Department of Health and Human Services suggest that one minute of vigorous activity is equivalent to ________ minutes of moderate activity.

Accepted Answer

The answer of Current physical activity guidelines from the Department...

Question 9

Why is moderate intensity activity positioned at the base of the activity pyramid?

Accepted Answer

Moderate intensity activity is positioned at the base of the activity pyramid because it can be performed by virtually all people, regardless of age and fitness level. This makes it the most accessible and inclusive choice for achieving physical activity goals.

Question 10

What is another term for Non-Exercise Activity Thermogenesis?

Accepted Answer

Non-exercise activity thermogenesis, or NEAT, refers to the calories we burn throughout the day as we go about our daily activities such as walking, standing, and other light movements, rather than intentional exercise.

Question 11

According to the book,what defines the "target zone" for step counts for healthy adults?

Accepted Answer

The answer of According to the book,what defines the "target...

Question 12

Which of the following statements is true?

Accepted Answer

The answer of Which of the following statements is true?
...

Question 13

Which of the following is used to describe moderate intensity activity?

Accepted Answer

METS (metabolic equivalents) measure the energy required for a physical activity. Moderate intensity activities are those that require 3-6 METS. A is incorrect because activities just above rest are considered light intensity. C is incorrect because where the activity can be done does not determine the intensity level. D is incorrect because a heart rate above 150 bpm does not necessarily mean the activity is moderate intensity, as heart rate can vary based on age, fitness level, and other factors.

Question 14

Walking as an exercise

Accepted Answer

Walking is the most popular leisure time activity and has numerous health benefits for people of all ages. It can improve cardiovascular health, increase endurance, and assist in weight management.

Question 15

__________ is the best example of lifestyle physical activity.

Accepted Answer

Raking leaves is a good example of lifestyle physical activity because it is a type of physical activity that is incorporated into daily routines and does not necessarily require a gym or structured exercise program. This type of activity is more sustainable long-term and can improve overall health and well-being.

Question 16

Activities that require 5 METS of energy are considered

Accepted Answer

Activities that require 5 METS of energy are considered moderate.

Question 17

Approximately how many calories would a 70 kg person burn if they exercised at 4 METS for 30 minutes?

Accepted Answer

A 70 kg person exercising at 4 METs for 30 minutes would burn approximately 140 calories. The formula to calculate calories burned is: Calories = METs x weight in kg x time in hours. So, 4 METs x 70 kg x 0.5 hours = 140 calories.

Question 18

Which of the following is NOT a benefit of moderate physical activity?

Accepted Answer

The statement "It promotes higher levels of fitness than aerobic sports" is incorrect. Aerobic sports are typically associated with higher levels of fitness due to their higher intensity and greater cardiovascular challenge. Therefore, A is not a benefit of moderate physical activity.

Question 19

__________________ means "in the presence of oxygen."

Accepted Answer

The term aerobic specifically refers to processes or organisms that require oxygen, therefore "in the presence of oxygen." Anaerobic means without oxygen. MET stands for metabolic equivalent, a measure of energy expenditure during physical activity, and moderate is a relative term referring to a moderate level of intensity or effort.

Question 20

Which of the following represents the activity recommendations from the original "Surgeon General's Report on Physical Activity and Health"?

Accepted Answer

The original "Surgeon General's Report on Physical Activity and Health" recommends expending about 1000 calories a week through physical activity for health benefits.
