(NA) Muscle Relationships, Skill + Health Components of Fitness Flashcards
agonist
the muscle doing the movement
-when a muscle contracts concentrically to create the desired joint motion + it supplies the majority of the tension needed to make the joint move, it is serving as an agonist
ex: medial deltoid in shoulder abduction
antagonist
regulates the movement + ensures that muscle joint actions aren’t too powerful
-when a muscle contracts to slow down an intended joint motion, it is serving as an antagonist
ex: lats in shoulder abduction
ex: chest pass
identify antagonist/agonist: pecs + rhomboid
-agonist = pecs
-antagonist = rhomboids
skill-related components of fitness relates more/less to sports than health-related copmonents

6 skill-related components of fitness
agility
reaction time
coordination
balance
power
speed
skill-related components of fitness
agility
the ability to rapidly change position in space with speed + accuracy
-if we had to choose between speed + agility we would be more concerned with agility
skill-related components of fitness
balance
the ability to control body position
skill-related components of fitness
coordination
the ability to use the body parts + senses together to produce smooth efficient movements
skill-related components of fitness
speed
the ability to move the body/parts of the body as quickly as possible
skill-related components of fitness
power
the combination of force (strength) + speed (velocity) in a muscle/group of muscles
-crucial for any team sport- if you are trying to score against a defender, you are using power
skill-related components of fitness
reaction time
the ability to respond consciously to an external stimulus
-reaction time is predominantly nervous system training
health-related components of fitness are related to what 2 things
-longevity
-healthy life outcomes
is there a direct connection between health-related components of fitness + sports
no
-there are people that have high performance of health-related copmonents but suck at sports
5 health-related components of fitness
muscular endurance
muscular strength
muscular flexibility
body composition
cardiovascular endurance
global aspects of health-related components of fitness
cardiovascular endurance + body composition
local aspects of health-related components of fitness
muscular strength, muscular endurance, muscular flexibility
health-related components of fitness
cardiovascular endurance
how well the heart, lungs, + vasculature deliver oxygen for muscle to utilize during exercise
what is the #1 component when talking about health
cardiovascular fitness
-also easiest to improve because we are aerobic organisms
-we don’t have many adaptations to make us more anaerobic; only time we see this shift is when someone is paralyzed
health-related components of fitness
body composition
how components of the body, typically divided into 2-compartments (fat mass + fat-free mass)
health-related components of fitness
muscular strength
how much force can be produced with maximal effort of a group/individual muscle
health-related components of fitness
muscular endurance
the ability of a muscle to continue contracting a muscle/group of muscles against resistance
health-related components of fitness
muscular flexibility
the ability of a joint or series of joints to move through full ROM
