Flashcards based on Physical Education lecture notes focusing on key vocabulary and concepts for exam preparation.

Component 04

Performance or Coaching Evaluation and Analysis of Performance for Improvement (EAPI)

Agonist

Muscle responsible for the movement at a joint

Antagonist

Muscle that lengthens or relaxes as the agonist contracts

Fixator

Muscle(s) that stabilize the joint where the origin of the agonist sits

Flexion

Joint angle decreases, limb moves forwards

Extension

Joint angle increases, limb moves backwards

Abduction

Limb moves away from midline

Adduction

Limb moves towards midline

Horizontal flexion

Limb parallel to ground and moves forwards

Horizontal extension

Limb parallel to ground and moves backwards

Medial rotation

Limb turns about its longitudinal axis towards midline of body

Lateral rotation

Limb turns about its longitudinal axis away from midline of body

Dorsi flexion

Toes lifted up towards shin

Plantar flexion

Toes pointed down towards ground

Sagittal plane

Divides body right & left

Frontal plane

Divides body front & back

Transverse plane

Divides body top & bottom

Isotonic contraction

Contraction causing movement or change in length of muscle

Isometric contraction

Contraction without movement or no change in muscle length
