Chapter 5

Question 1

Kinetic chain

Answer 1

joints and muscles and how they work together to perform movement

Question 2

open kinetic chain

Answer 2

distal ends is not fixed to a stable surface
Ex: bicep curl

Question 3

Closed kinetic chain

Answer 3

distal end is fixed
Ex: deadlift

Question 4

what can we learn from studying human movement

Answer 4

identify, deficits, quantity, performances

Question 5

discrete motions

Answer 5

clear ending and beginning
EX: situp

Question 6

Continuous motion

Answer 6

no clear ending or beginning
Ex: walking

Question 7

describe two common ways that movement is broken down into phases

Answer 7

time specific: frame or time increments
task/skill specific: based on a goal movement

Question 8

How can joint motion occur without contraction

Answer 8

external forces acting on it

Question 9

what are the four phases of a baseball pitch

Answer 9

stance
preparatory
movement
follow through

Question 10

what occurs in the stance phase

Answer 10

stable balance position of the joint
isometric contraction

Question 11

what occurs during the preparatory phase

Answer 11

wind-up
preparing for pitch
lengthening muscles ( optimal lengthen)

Question 12

what occurs during the movement phase

Answer 12

acceleration phase/ action phase
speeding up joints
concentric contraction

Question 13

what occurs during the follow through phase

Answer 13

deceleration phase
slowing the body down/ control movement
antagonist muscles activated
