Movement Flashcards
Agonist
The muscle responsible for the movement of a joint
Contracts
Antagonist
The muscle that lengthens or relaxes as the agonist contracts.
Fixator
The muscle that stabilises the joint where the origin of the agonist sits
Helps agonist function efficiently
Shoulder flex lion
Agonist anterior deltoid
Antagonist posterior deltoid
Eg upwards phase of a ball toss in tennis serve
Shoulder extension
Agonist posterior deltoid
Antagonist anterior deltoid
Example is preparation phase of receiving baton in relay
Shoulder abduction
Agonist medial deltoid
Antagonist latissimus Doris
Shoulder adduction
Agonist latissimus Doris
Antagonist medial deltoid
Shoulder Circumduction
Rotator cuffs group acts as the antagonist and agonist
Medial rotation
To the middle of the body
Rotator cuff group antagonist and agonist
Example is right arm in execution phase of a left pass in rugby
Lateral rotation
Rotator cuff group acts as the antagonist and agonist
Example is ultimate frisbee backhand
Horizontal flexion
To body
Pectoralis major agonist
Teres minor antagonist
Eg execution phase of discuss
Horizontal extension
Teres minor acts as agonist
Pectoralis major antagonist
Eg preparation phase of discuss throw
Elbow flexion

Gluteus minimus antagonist
Hip lateral rotation
Gluteus minimus agonist
Gluteus medius antagonist
Knee flexion
Bicep fermoris acts as agonist
Rectus fermoris acts as antagonist
Knee extension
Rectus fermoris agonist
Bicep fermoris antagonist
Plantar flexion
Gastrocnemius agonist
Tibialis anterior antagonist
