KNH 188 EXAM 2 MIAMI UNIVERSITY- JENNIFER TIMMERMAN EXAM QUESTIONS & ANSWERS
TEST QUESTIONS AND VERIFIED SOLUTIONS |2026| ELABORATED &DETAILED ANSWERS!
Question 1
How does the World Health Organization (WHO) specifically define physical activity?
A) Planned and structured bodily movements intended to improve health
B) Any bodily movement produced by skeletal muscles that requires energy expenditure
C) Repetitive movements aimed at increasing heart rate
D) Competitive sports and organized athletic events
E) Movements performed at a moderate to vigorous intensity for at least 30 minutes
Correct Answer: B) Any bodily movement produced by skeletal muscles that requires energy
expenditure
Rationale: WHO defines physical activity broadly to include all movements, whether for
work, play, or transport. Options A and E describe specific subsets of physical activity, but
the definition covers any movement requiring energy via skeletal muscles.
Question 2
Which of the following statements best describes the relationship between exercise and physical
activity?
A) All physical activity is exercise
B) All exercise is physical activity, but not all physical activity is exercise
C) Exercise and physical activity are two completely unrelated behaviors
D) Physical activity is a subset of exercise
E) Exercise refers only to activities involving heavy weights
Correct Answer: B) All exercise is physical activity, but not all physical activity is exercise
Rationale: Exercise is a specific category of physical activity that is planned, structured, and
repetitive with the goal of improving or maintaining physical fitness. General physical
activity includes unplanned movements like walking to class or gardening.
Question 3
What is the primary purpose of using Metabolic Equivalents (METs) in physical activity
research?
A) To measure the exact number of steps a person takes
B) To provide a standardized way to describe the absolute intensity of various activities
C) To calculate the amount of weight a person can lift
D) To measure the flexibility of a joint
E) To determine a person's exact body fat percentage
Correct Answer: B) To provide a standardized way to describe the absolute intensity of
various activities
Rationale: METs allow researchers and practitioners to compare the energy cost of different
activities. One MET represents resting energy expenditure, and higher MET values
represent multiples of that rest state.

Question 4
A single MET is equivalent to which of the following physiological measurements?
A) 5.0 ml O2/kg/min
B) 1.0 ml O2/kg/min
C) 3.5 ml O2/kg/min
D) 10.0 ml O2/kg/min
E) 2.2 ml O2/kg/min
Correct Answer: C) 3.5 ml O2/kg/min
Rationale: By definition, 1 MET is the approximate amount of oxygen consumed while
sitting at rest, which is standardized as 3.5 milliliters of oxygen per kilogram of body
weight per minute.
Question 5
An activity that requires 2.5 METs would be classified as what intensity level?
A) Sedentary
B) Light
C) Moderate
D) Vigorous
E) Maximal
Correct Answer: B) Light
Rationale: Intensity is categorized by MET ranges. Light intensity physical activity is
defined as falling between 2.0 and 2.9 METs.
Question 6
Which MET range corresponds to "Moderate" intensity physical activity?
A) 1.0 - 2.0 METs
B) 2.0 - 2.9 METs
C) 3.0 - 5.9 METs
D) 6.0 - 8.0 METs
E) ≧ 10.0 METs
Correct Answer: C) 3.0 - 5.9 METs
Rationale: Moderate intensity is standardized in health guidelines as any activity requiring
3.0 to 5.9 times the energy of resting state.
Question 7
According to the ACSM, what is "Physical Fitness"?
A) The absence of disease or infirmity
B) The ability to run a marathon without stopping
C) The ability to carry out daily tasks with vigor and alertness without undue fatigue
D) A measure of a person's maximum strength
E) The psychological desire to engage in sports
, 3
Correct Answer: C) The ability to carry out daily tasks with vigor and alertness without
undue fatigue
Rationale: ACSM defines fitness as a set of attributes that allow the body to respond to
stress and the energy to enjoy leisure-time pursuits and meet emergencies.
Question 8
What is the fundamental difference between physical activity and physical fitness?
A) Physical activity is a capacity; physical fitness is a behavior
B) Physical activity is a behavior; physical fitness is a capacity
C) They are the same thing and used interchangeably
D) Physical fitness is the movement; physical activity is the result
E) Physical activity can only be measured in a lab
Correct Answer: B) Physical activity is a behavior; physical fitness is a capacity
Rationale: Physical activity refers to the actual "doing" (behavior), while physical fitness
refers to how capable the person is (capacity). Fitness is achieved by consistently
performing physical activity.
Question 9
Which health-related component of fitness is defined as the ability to perform prolonged, large-
muscle, dynamic exercise at moderate to high levels of intensity?
A) Muscular strength
B) Flexibility
C) Cardiorespiratory endurance
D) Agility
E) Muscular endurance
Correct Answer: C) Cardiorespiratory endurance
Rationale: This depends on the ability of the circulatory and respiratory systems to supply
oxygen to the muscles during sustained physical effort.
Question 10
Muscular strength is best defined as:
A) The ability of a muscle to perform repetitive contractions without fatigue
B) The range of motion available at a joint
C) The ability of a muscle to produce force
D) The rate at which work is performed
E) The relative amount of fat versus muscle in the body
Correct Answer: C) The ability of a muscle to produce force
Rationale: While muscular endurance involves repetitive contractions, strength is
specifically the maximum force a muscle can generate in a single effort.
