Joints,Muscles And Movement Flashcards
What is the agonist and give a sporting example.
Definition- The muscle that’s directly responsible for the movement at a joint.
Sporting example- Upward phase of the bicep curl.
What is the antagonist and give a sporting example.
Definition- As one muscle shortens to produce movement, another muscle lengthens to allow that movement to take place.
Sporting example- Upward phase of the hamstring curl.
What is the fixator and give a sporting example.
Definition- Muscle responsible for stabilising a joint.
Sporting example- Bicep curl as the trapezius remains in a constant state of tension to support the shoulder joint.
What is the concentric phase and give a sporting example.
Definition- Muscle shortens while producing tension. Sporting example- Striking of a ball or the upward phase of lifting a weight or swinging a tennis racket.
What is the eccentric phase and give a sporting example.
Definition- Muscle lengthening while producing tension. Sporting example- A squat or the downward phase of lifting a weight.
What is the isometric phase and give a sporting example.
Definition- Muscle contracting creates a force but no movement takes place.
Sporting example- Deltoid in the crucifix on the rings in gymnastics.
