KNH 188 EXAM 2 QUESTIONS WITH VERIFIED
ANSWERS
WHO defines physical activity as - Answers - "any bodily movement produced by
skeletal muscles that requires energy expenditure."
Exercise is a subset of physical activity - Answers - Exercise = A type of physical activity
consisting of planned, structured, and repetitive bodily movement done to improve or
maintain one or more components of physical fitness
All exercise is physical activity - Answers - but not all physical activity is exercise
METs - Answers - are a useful convenient and standardized way to describe the
absolute intensity of a variety of physical activities.
A MET is a multiple of your estimated resting energy expenditure - Answers - "Energy
expenditure refers to the amount of energy an individual uses to maintain essential body
functions (respiration, circulation, digestion) and as a result of physical activity." -
Heaney
1 MET = 3.5 ml O2/kg/min (the amount of oxygen consumed while sitting at rest) -
Answers - Light intensity PA = 2.0-2.9 METs
Moderate PA = 3.0-5.9 METs
Vigorous PA ≧ 6.0 METs
What is Physical Fitness? - Answers - is the ability to carry out daily tasks with vigor and
alertness, without undue fatigue, and with ample energy to enjoy leisure-time pursuits
and meet unforeseen emergencies. (ACSM) A set of physical attributes that allows the
body to respond or adapt to the demands and stress of physical effort. A measure of
how capable a person is to perform. These attributes can occur naturally in a person, or
be achieved through training. There are health-related attributes and skill-related
attributes.
How does physical activity differ from physical fitness? - Answers - Physical Activity =
Behavior;
Physical Fitness = capacity Physical fitness is accomplished by performing physical
activity
Cardiorespiratory Endurance - Answers - The ability to perform prolonged, large-
muscle, dynamic exercise at moderate to high levels of intensity (due to the ability of the
circulatory and respiratory system to supply oxygen during sustained physical activity).
Muscular strength - Answers - The ability of the muscle to produce force.
, Muscular Endurance - Answers - The ability of muscle to continue to perform without
fatigue.
Flexibility - Answers - The range of motion (ROM) available at a joint.
Body Composition - Answers - The relative amounts of muscle, fat, bone, and other vital
parts of the body.
Speed - Answers - The ability to perform a movement within a short period of time.
Power - Answers - The ability or rate at which one can perform work; a function of work
& time.
Agility - Answers - The ability to change the position of the body in space with speed
and accuracy.
Balance - Answers - The maintenance of equilibrium while stationary or moving.
Coordination - Answers - The ability to use the senses, such as sight and hearing,
together with body parts in performing tasks smoothly and accurately.
Reaction Time - Answers - The time elapsed between stimulation and the beginning of
the reaction to it.
Skill-related components of physical fitness are also referred to as neuromuscular
fitness - Answers - Neuromuscular = the complex control of muscles and movement by
the brain and spinal column.
AEROBIC ACTIVITY - Answers - adults should do at least 150 minutes to 300 minutes
a week of moderate-intensity, or 75 minutes to 150 minutes a week of vigorous-intensity
aerobic physical activity.
Can be a combination of moderate- and vigorous-intensity activity Preferably aerobic
activity should be spread throughout the week.
Additional health benefits are gained by engaging in physical activity beyond the
equivalent of 300 minutes of moderate-intensity physical activity a week.
MUSCULAR STRENGTH - Answers - In addition to aerobic activity, adults should also
do muscle-strengthening activities of moderate or greater intensity and that involve all
major muscle groups on 2 or more days a week, as these activities provide additional
health benefits.
PA for older adults - Answers - older adults should do multicomponent physical activity
that includes balance training as well as aerobic and muscle-strengthening activities.
Older adults should determine their level of effort for physical activity relative to their
level of fitness.
