Deck 9: Intensity Monitoring

Question 1

ACE literature states that you probably won't ever use the formula in real life and you won't be tested on it, so why do you need to understand the Fick Equation? Because the Fick Equation measures:

A)The rate at which the body uses oxygen during physical activity
B)The rate at which the body burns calories during physical activity
C)The relationship between respiratory rate and heart rate during physical activity
D)The rate at which the muscles use glycogen during physical activity

Answer 1

The rate at which the body uses oxygen during physical activity

Question 2

Before endurance events, athletes will often "carb up." Where does the body obtain the glucose from broken-down carbohydrates while exercising?

A)Glycogen stored in muscle tissue
B)Glucose in the bloodstream
C)Glucose stored in the liver
D)Glycogen stored in the muscle tissue and glucose stored in the bloodstream

Answer 2

Glycogen stored in the muscle tissue and glucose stored in the bloodstream

Question 3

Prolonged exercise causes the body's temperature to increase. The Group Fitness Instructor can provide advice on how to best reduce the ill-effects of overheating, so their class members do not "lose steam," before the end of class. In order to decrease body heat, the body uses WHICH of the following:

A)Ventilation, radiation, conduction, and evaporation
B)Evaporation, ventilation, metabolism, and digestion
C)Conduction, ventilation, convection, and evaporation
D)Radiation, conduction, convection, and evaporation

Answer 3

Radiation, conduction, convection, and evaporation

Question 4

Once the warm-up portion of an exercise class is over, it's time to elevate heart rates, amp up the intensity and create group participation. Changes in music and choreography trigger an increase in sympathetic activity, which then creates WHICH of the following cardiovascular change(s):

A)A decrease in stroke volume
B)A decrease in heart rate and contractility
C)An increase in heart rate and contractility
D)Redistribution of blood flow to the heart and lungs

Question 5

Epinephrine and nor epinephrine, also called catecholamine's, are hormones of the sympathetic nervous system. Which of the following is NOT a physiological response influenced by catecholamine's?

A)Increased contractility, resulting in increased cardiac output
B)Decreased systolic blood pressure
C)Vasoconstriction in non-exercising muscles and vasodilation of cardiac and exercising skeletal muscle
D)Dilation of the respiratory passages to aid in ventilation.

Question 6

Group Fitness Instructors who understand the three stages of learning motor skills can tap into deeper understanding of "how people learn to move". What are the three stages of learning?

A)Cognitive, Motor, Sensory
B)Cognitive, Associative, Autonomous
C)Learned, Associative, Independent
D)Learned, Assisted, Autonomous

Question 7

According to the American College of Sports Medicine's (ACSM) 2011 "Guidance for Prescribing Exercise", the following would represent the minimum amount of cardiopulmonary exercise an adult should perform:

A)90 minutes/week, moderate- to vigorous-intensity
B)120 minutes/week, moderate-intensity
C)150 minutes/week, minimum-intensity
D)150 minutes/week, moderate-intensity
