UVIC EPHE 143 MIDTERM STUDY GUIDE
Epidemology - Answers -the branch of medicine that deals with the incidence,
distribution, and possible control of diseases and other factors relating to health.
physical activity - Answers -any bodily movement produced by skeletal muscles that
results in energy expenditure
Physiology - Answers -The branch of biology deals with the normal functions of living
organisms.
Krogh Principle - Answers -for every physiological problem there is an animal optimally
suited to yield an answer
V02 max - Answers -The highest rate of oxygen transport and utilization achieved at
maximal physical exertion.
Heart Rate (HR) - Answers -number of heart beats per minute
Stroke Volume (SV) - Answers -The volume of blood pumped forward with each
ventricular contraction.
cardiac output - Answers -The volume of blood ejected from the left side of the heart in
one minute.
Fick equation - Answers -VO2 = Q x a-vO2 difference
Oxygen delivery - Answers -Ventilation of the lungs
Diffusion of oxygen from the alveoli into the capillary blood
Perfusion of systemic capillaries with oxygenated blood
Diffusion of oxygen from systemic capillaries into the cells
oxygen extraction - Answers --the amount of O2 that is taken up by the muscle and
removed from the blood at the capillaries
-increases during exercise
-during rest: tissues extract 25% of oxygen from blood
-during exercise: tissues extract 75-85% of oxygen from blood
-difference of arterial VO2
Arterial O2 content - Answers -the amount of O2 in the systemic arteries being
delivered to cells of the body
Respiratory Exchange Ratio (RER) - Answers -the ratio of carbon dioxide expired to
oxygen consumed at the level of the lungs
, Absolute VO2 - Answers -(Relative VO2) x (kg)
Relative VO2 - Answers -A volume of O2 consumption relative to unit of body mass
and time
Expressed as ml/kg/min
Used for weight-bearing modalities
Best for comparing people of different body size
Muscular Strength - Answers -The amount of force a muscle can exert
motor behavior - Answers -bodily motion that occurs as a result of self-initiated force
that moves the bones and muscles
motor learning - Answers -Integration of motor control processes through practice and
experience, leading to a relatively permanent change in the capacity to produce skilled
movements.
motor control - Answers -How the central nervous system integrates internal and
external sensory information with previous experiences to produce a motor response.
Motor Devlopment - Answers -the emergence of the ability to execute physical action
motor skills - Answers -the learned abilities to move some part of the body, in actions
ranging from a large leap to a flicker of the eyelid
open skill - Answers -a skill performed in an environment that is unpredictable or in
motion and that requires performers to adapt their movements in response to dynamic
properties of the environment
closed skill - Answers -a skill performed in an environment that is predictable or
stationary and that allows performers to plan their movements in advance
Reflex Theory - Answers -Stimulus applied to muscle results in stereotypical responses
referred to as a reflex (peripherally based)
-afferent sensory inputs are necessary pre-requisite for efferent motor outputs.
information processing model - Answers -model of memory that assumes the
processing of information for memory storage is similar to the way a computer
processes memory in a series of three stages
