(NA) Muscle Relationships, Skill + Health Components of Fitness

Question 1

agonist

Answer 1

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

Question 2

antagonist

Answer 2

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

Question 3

ex: chest pass

identify antagonist/agonist: pecs + rhomboid

Answer 3

-agonist = pecs
-antagonist = rhomboids

Question 4

skill-related components of fitness relates more/less to sports than health-related copmonents

Answer 4

more

Question 5

6 skill-related components of fitness

Answer 5

agility
reaction time
coordination
balance
power
speed

Question 6

skill-related components of fitness

agility

Answer 6

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

Question 7

skill-related components of fitness

balance

Answer 7

the ability to control body position

Question 8

skill-related components of fitness

coordination

Answer 8

the ability to use the body parts + senses together to produce smooth efficient movements

Question 9

skill-related components of fitness

speed

Answer 9

the ability to move the body/parts of the body as quickly as possible

Question 10

skill-related components of fitness

power

Answer 10

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

Question 11

skill-related components of fitness

reaction time

Answer 11

the ability to respond consciously to an external stimulus

-reaction time is predominantly nervous system training

Question 12

Answer 12

-longevity
-healthy life outcomes

Question 13

is there a direct connection between health-related components of fitness + sports

Answer 13

no
-there are people that have high performance of health-related copmonents but suck at sports

Question 14

muscular strength
muscular flexibility
body composition
cardiovascular endurance

Question 15

global aspects of health-related components of fitness

Answer 15

cardiovascular endurance + body composition

Question 16

local aspects of health-related components of fitness

Answer 16

muscular strength, muscular endurance, muscular flexibility

Question 17

health-related components of fitness

cardiovascular endurance

Answer 17

how well the heart, lungs, + vasculature deliver oxygen for muscle to utilize during exercise

Question 18

what is the #1 component when talking about health

Answer 18

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
