Chapter 1 Flashcards
what is genotype?
describes the genetic constitution of an individual
what is phenotype?
measurable traits or characteristics
ex. blue eyes or aggressive behavior
relationship between genotype and phenotype?
genotype + environment = phenotype
epigenetics
Study of Changes in the phenotype due to changes in the way genes express themselves (not due to actual changes in the DNA)
what are the 5 components of fitness
- cardiorespiratory (aerobic) endurance
- muscular strength
- muscular endurance
- flexibility
- body composition
considered health-realted components
Cardiorespiratory endurance
people are good at delivering oxygen to their muscles to fuel work
related to agility
Muscular strength
the ability to produce force under a finite set of biological conditions
related to balance
muscular endurance
the ability for a muscle to work best over time
related to coordination
flexibility
ability to optimize range and motion of a joint
related to power
Body component
ratio of fat to muscle
governed by genetics
