What are the 5 pillars of public health? - Answers - 1. epidemiology
2. environmental health
3. health promotion/education
4. health administration/policy
5. biostatistics
What is public health? - Answers - health of a population as a *whole*
What is chronic disease? - Answers - illness/disease that persists over time (ex.
coronary artery disease, cancer, diabetes)
What is Epidemiology? - Answers - studying the causes and effects of diseases in order
to reduce risk factors
What is Kinesiology? - Answers - 1. exercise physiology
2. movement science
3. sports and exercise psychology
London Bus Conductors & Postal Workers - Answers - Dr. Jeremy Morris:
-studied heart disease and inactivity with london bus drivers and postal workers
-found that postal workers have reduced risk of heart disease
Who is Dr. Ralph Paffenbarger? - Answers - -student of Dr. Morris
-furthered Morris' study by determining how much activity is necessary to reduce risk of
heart disease
Who is Dr. Steven Blair? - Answers - -conducted *Aerobic Longitudinal Study*
-"the more inactive you are, the higher your risk of death"
What is Physical Activity? - Answers - any physical movement that increases energy
expenditure above resting
What are the benefits of activity? - Answers - 5,000 steps per day = heart health
10,000 steps per day = manage weight
What does FITT stand for? - Answers - Frequency: how often
Intensity: how hard
Time (duration): how long
Type: mode
What are the exercise principles? - Answers - -progressive overload: gradual increase
of demand on muscles
, -specificity of training:
making adaptations to to a specific group of muscles/muscle systems
-variability: mix up workouts to avoid burnout
-reversibility: what you don't use you lose
What is cardiovascular endurance? - Answers - cardio-respiratory-vascular-muscular
endurance
(heart-lungs-blood vessels-muscles)
What is caloric expenditure? - Answers - how many calories you burn
What is gross energy expenditure? - Answers - the number of calories burned during
activity combines with number of calories burned at rest
What is net energy expenditure? - Answers - calories burned during exercise/activity
What is Metabolic Equivalent (MET)? - Answers - measurement of how much oxygen
and energy your body uses at rest
What is accumulation? - Answers - how much activity you can accumulate over the
course of a day
What is dose response? - Answers - how much exercise is needed to benefit your
health/body
What is Aerobic Metabolism? - Answers - Muscles cannot contract repeatedly without:
-Oxygen - provided by the CV system
-Energy - provided by food (CHO and fat)
What is VO2? - Answers - the amount of O2 the body can take in and use for work
(mL/kg/min)
What is heart rate? - Answers - how many times your heat beats (min)
What is stroke volume? - Answers - amount of blood pumped by the heart per heart
beat
What is cardiac output? - Answers - amount of blood pumped from heart per beat per
minute (HR x Stroke Volume)
What is oxygen extraction? - Answers - muscles ability to remove O2 from blood and
use it for energy
(CaO2 - CvO2 : content of arterial blood - content of venous blood)
Functions of arteries and veins - Answers - arteries: carry O2 rich blood *away* from
heart
