Q

The US Physical Activity Guidelines for Americans include all of the following EXCEPT:

A) Regular exercise reduces the risk of developing a chronic disease.

Q

_____ is defined as “any bodily movement produced by the contraction of skeletal muscle that increases energy expenditure above a basal level.”

A) Physical activity

B) Fitness

C) Exercises

D) Isokinetic exercise

A

A. Physical activity.
Fitness is defined as “the ability to carry out daily tasks with vigor and alertness without undue fatigue, with ample energy to enjoy leisure-time pursuits and the ability to respond to emergencies.”
Exercise is a subset of physical activity that is formally defined as “physical activity that is planned, structured, repetitive, and purposeful in the sense that the improvement or maintenance of one or more components.”
Isokinetic exercise is a type of strength training that uses special machines or dynamometers to maintain a constant (iso) speed (kinetic) of movement.

Q

According to the study by Naci and Ioannidis, exercise is equal to, or superior to, medication with regards to mortality for the treatment of:

  1. Post-stroke
  2. Secondary prevention of coronary artery disease (CAD) and pre-diabetes
  3. Heart failure

A) 2

B) 1 and 2

C) 1 and 3

D) 2 and 3

E) All of the above

A

B. 1 and 2.
This meta-epidemiological study included 305 randomized controlled trials (RCTs) and found that exercise decreased mortality more than medications in post-stroke studies. Exercise also had an equivalent effect on mortality to medications for the secondary prevention of coronary artery disease (CAD) and pre-diabetes, but it was inferior to medications with regard to heart failure patients.

Q

When counseling patients on physical activity, one approach is to use the 5A’s. What is the correct order that these steps should be delivered in?

A) Ask, assess, assist, agree, arrange

B) Ask, assess, assist, advise, arrange

C) Assess, advise, assist, arrange, agree

D) Assess, advise, agree, assist, arrange

E) Ask, advise, assist, agree, arrange

A

D. The correct order is: assess, advise, agree, assist, arrange.

The 5A’s begin with assessing patient beliefs, behaviors, and knowledge,
then advising by providing information about the health benefits of change,
and then agreeing on a collaborative goal.
Next, the provider assists the patient in identifying barriers, strategies and problem-solving techniques
before finally arranging to follow up on plans.

and for tobacco or intervention counseling are Ask, Advise, Assess, Assist, and Arrange.

17
Q

With regard to pre-participation screening, what are the major disease entities one needs to consider when deciding whether additional medical clearance is needed?

  1. Cardiovascular disease
  2. Pulmonary disease
  3. Renal disease
  4. Metabolic disease

A) 1, 3 and 4

B) 1 and 2

C) 1

D) 1, 2 and 3

E) All of the above

A

A. 1, 3 and 4.
Referral to a health provider should be made on the basis of current physical activity levels and presence of signs or symptoms and/or known cardiovascular, metabolic or renal disease. While one might modify an exercise prescription for someone with pulmonary disease, pulmonary disease alone does not require medical clearance, as it has not been shown to increase the risk of cardiovascular complications.

[Riebe D, et al. Updating ACSM’s Recommendations for Exercise Preparticipation Health Screening. 2015;47:2473-2479.]

18
Q

When using the Talk Test as an exercise intensity measure, a patient performing vigorous-intensity exercise is able to _____.

A) Sing but not talk

B) Talk but not sing

C) Sing or talk

D) Barely talk

E) None of the above

A

D. Barely talk
The Talk Test is an intensity measure that’s easy for patients to perform on their own.
Very light or light activity should allow patients to talk and/or sing without difficulty (HR 63% or less of maximal).
Moderate exercise (64 to 76% of maximal) should allow individuals to talk but not sing (Answer C).
Vigorous to maximal exercise (77 to 100% of maximal) should make it difficult for an individual to talk or hold a conversation.

[Persinger R, et al. Consistency of the talk test for exercise prescription. Med Sci Sports Exerc, 2004. 36(9): p. 1632-6.]

19
Q

Who should be referred to a health provider for medical clearance prior to starting a moderate- intensity exercise program?

A) A 45-year-old male who has no known cardiovascular, metabolic or renal disease, and who does not currently participate in regular exercise and is asymptomatic.

B) A 55-year-old male who has known cardiovascular disease, currently participates in regular exercise and is asymptomatic.

C) A 30-year-old female who has known diabetes, does not currently participate in regular exercise and is asymptomatic.

D) More than one of the above.

E) None of the above.

A

C. A 30-year-old female who has known diabetes, does not currently participate in regular exercise and is asymptomatic.

An asymptomatic male with no known cardiovascular, metabolic or renal disease does not require medical clearance before beginning a moderate-intensity or vigorous-intensity exercise program.

An adult with known cardiovascular, metabolic or renal disease who is already participating in regular moderate-intensity exercise and is asymptomatic does not need a referral for moderate-intensity exercise. However, a referral is recommended if they want to pursue vigorous-intensity exercise.

It’s recommended that an adult with known cardiovascular, metabolic (e.g., diabetes), or renal disease who does not currently exercise should be referred for medical clearance, even if they are asymptomatic.

Any symptomatic individual should be referred for medical clearance.

[Riebe D, et al. Updating ACSM’s Recommendations for Exercise Preparticipation Health Screening. 2015;47:2473-2479.]

Q

For 5% weight loss, many people need to do more than _____ per week of moderate-intensity activity.

A) One hour and 15 minutes

B) Two and a half hours

C) Five hours

D) Seven hours

A

C. Five hours.
People who want to lose a substantial amount of weight (more than 5% of body weight) and people who are trying to keep a significant amount of weight off once it has been lost need a high amount of physical activity unless they also reduce their caloric intake. Many people need to do more than 300 minutes of moderate-intensity activity a week to meet weight–control goals.
Seventy-five minutes is likely insufficient to meet health recommendations or weight loss goals.
Two and a half hours would be appropriate for general health benefits.
Seven hours may offer additional health benefits and further assist with weight loss efforts.

[CDC. 2008 Physical Activity Guidelines. Active Adults. 2008. [2/25/18]; Available from https://health.gov/ paguidelines/guidelines/chapter2.aspx.]

21
