types of movement, contractions, and the ssc

Flashcards covering key concepts, terms, and definitions related to applied anatomy and physiology for physical education.

Muscular Skeletal System

The organ system consisting of skeletal muscles and bones that facilitates movement and supports the body.

Flexion

Bending a joint to decrease the angle between two body parts.

Extension

Increasing the angle between two body parts.

Abduction

Moving a body part away from the midline.

Adduction

Moving a body part towards the midline.

Rotation

The movement of a bone around its axis.

Circumduction

A circular movement that combines flexion, extension, abduction, and adduction.

Stretch-Shortening Cycle (SSC)

A neuromuscular phenomenon involving an eccentric contraction followed by a rapid concentric contraction to enhance performance.

Concentric Contraction

A type of muscle contraction in which the muscle shortens as it contracts.

Eccentric Contraction

A type of muscle contraction in which the muscles lengthen as they contract.

Isometric Contraction

A type of muscle contraction where the muscle remains the same length while contracting.

Agonist

The muscle primarily responsible for producing a specific movement.

Antagonist

The muscle that opposes or acts in the opposite direction to the agonist.

Fixator

A muscle that stabilizes the origin of the prime mover.

Synergist

A muscle that assists the prime mover in its action.

Plyometric Training

Training that includes quick, explosive movements to enhance the stretch-shortening cycle performance.

Dorsiflexion

The movement of raising the toes upwards.

Plantar Flexion

The movement of standing on tiptoes.
