Deck 7: Physical Activity, Health, and Weight Management

Question 1

Adipose tissue in people who engage in regular physical activity appears to becomes more sensitive to catecholamines.This advantage is lost when people stop exercising.

Answer 1

True

Question 2

People who are taking beta-blockers cannot use calculated HR as an indicator of exercise intensity.

Answer 2

True

Question 3

The American College of Sports Medicine (ACSM)suggests that several 10 minute activity segments can be just as effective as one continuous exercise session for low fitness individuals.

Answer 3

True

Question 4

Men may be more inclined than women to increase calorie consumption following exercise.

Question 5

To monitor the intensity of exercise using HR, an individual needs to pause for a minimum of 60 seconds during exercise.

Question 6

As people get older, the MET value that corresponds with moderate activity progressively increases.

Question 7

Research shows that physical activity must be continuous to be effective.

Question 8

Exercisers often lose less weight than dieters.

Question 9

Exercisers lose less fat than individuals who follow calorie restricted diets.

Question 10

Low intensity physical activity suppresses food consumption to a greater degree than high intensity physical activity.

Question 11

Skeletal muscle 3-hydroxyacyl COA dehydrogenase (HADH)levels increase after high intensity interval and endurance training.

Question 12

Even with personal trainers and high amounts of physical activity, most people who lose weight regain some of it.

Question 13

Lean tissue is always lost when low calorie diets are followed, whereas fats account for the majority of weight lost through physical activity.

Question 14

Heart rate increases proportionately with oxygen uptake, so HR can be used to gauge the intensity of exercise in place of VO₂ max testing.

Question 15

Higher amounts of activity are needed to prevent weight regain than the U.S.government recommends for health.

Question 16

Lipids make their greatest contribution to metabolism during exercise at about 65% of maximal oxygen uptake (VO₂ max).

Question 17

Smokers, even young people in good health, may have a blunted HR response to exercise.

Question 18

People who engage in regular activity and improve their physical fitness use more lipids for fuel and begin burning fat earlier during exercise.

Question 19

There is a great deal of individual variation in appetite response to physical activity.

Question 20

About the same amount of exercise is needed to improve fitness as is needed to improve health.

A)5,000 steps
B)7,500 steps
C)10,000 steps

D)All of the above

Question 35
