Test 1 Flashcards
What is health
A state of complete physical, mental and social well-being and not merely the absence of disease or infirmity
What are the dimensions of wellness
Physical Occupational Social Intellectual Spiritual Emotional
What is an infectious disease
something you can catch from someone else
what is a chronic disease
diseases that effect us for a long period of time and slowly develop
influenced by lifestyle and genetics
What are the pillars of public health
epidemiology and disease control
environmental health
health promotion and health education
What is physical activity
any bodily movement
What is exercise
activity that enhances an aspect of fitness, specific and intentional actions
what is fitness
attainment of specific criteria to function efficiently and effectively
What are the health related aspects of fitness
cardiovascular endurance muscular endurance muscular strength flexibility body composition
What are the skill related aspects of fitness
agility balance coordination power speed reaction time
What are the metabolic fitness components
blood sugar levels
blood lipid levels
blood hormone levels
What is bone integrity
bone density and strength
what is kinesiology
study of physiological process and anatomy of the body during movement
What are case studies
describes what happens to one or a few individuals
ex: graded exercise science test
What is a cross sectional study
when you compare different groups of people at a given point in time
ex: fit vs. unfit
what is a longitudinal study
studies group of people over a long period of time and are able to study long term behaviors and outcomes
what is an experimental study
it examines a group before and after training and identifies pre/post changes over time
What are the types of muscle movement
sliding filament theory
muscle contraction
aerobic
anaerobic (no oxygen for ATP)
Muscle fibers stained light, anaerobic and suited to strength and speed
Fast twitch muscle fiber
muscle fibers stained dark, aerobic and suited to endurance activity
slow twitch muscle fiber
What does the body use for energy production
food (fats, protein, carbohydrates)
ATP
Anaerobic Immediate source for energy
creatine phosphate system
~10 seconds
Anaerobic short-term source for energy
Glycolysis- glucose stored in cell and within muscle
ATP and pyruvate
(~20-120 seconds)
Aerobic long term source for energy
ocydative phosphorylation
uses fat as energy source
(3+ minutes)
Graded exercise test (GXT)
heart rate blood pressure rating od perceived exertion gas exchange blood lactate
What does GXT determine
normal response to exercise
maximal aerobic capacity
VO2 max
VO2 max formula
= mL/ kg (body weight)/ minutes
Gross energy expenditure
PA plus resting EE
Net energy expenditure
PA only
Resting energy expenditure
1 MET
Metabolic Equivalent
MET
1 MET equivalents
1 MET= 3.5 mL O2/ kg/ min
1 MET= 1 kcal/ kg/ hour
What is heart rate
frequency of heart beats/minute
