Week 1 Flashcards
top 4 causes of death in canada
cancer, heart disease, stroke, respiratory diseases
6 dimensions of wellness
- physical
- emotional
- intellectual
- spiritual
- interpersonal and social
- environmental
Health as a continuum
death, neutral, and wellness are distinct by illness and increasing health, wich are catagorized by mental, physical and emotional traits
evolutionary perspective on fitness
our environment allows for our genotype to be expressed in a more beneficial way
genotype + environment = phenotype
Epigenetics defnition
the study of heritable changes in phenotype caused by mechanisms other than DNA sequence (AKA EXERCISE)
Cardiovascular Endurance
ability of our body systems to deliver oxygen to our heart and working muscles
Muscular Strength
ability of muscles or groups of muscles to exert a force
Muscular Endurance
ability to apply submaximal force over a period of time
Flexability
optimizing range of motion at a particular joint
Body composition
amount of bone/muscle mass/adipose tissue
Performance related components
- power
- speed & quickness
- agility
- balance
- motor skill
Back injuries & motor control
- muscle imbalances are the primary cause of back problems
- coordination of the spinal musculature is also essential to back health
Overload Principal
GAS - general adaptation syndrome explains that any stress threatens the organism, diminishing the capacity of organism, responding through adapting
Supercompensation
enhancing an organisms compacity through stresses
How is overload accomplished
modulating one of [intensity/duration/frequency] while keeping the other two factors consistent
Specificity Principle
specific exercise elicits specific adaptations that create specific training efects
SAID defenition
specific adaptations to imposed demand
Reversibility principle
“use it or lose it”
- fitness levels decay if you do not continue stressing the system
Individual Differences Principle
training programs must meet individual needs and capacities of each participant
Responsiveness defenition
similar training templates can be used but rates of improvement are based on individual responsiveness
