Q

What is the agonist and antagonist in ankle dorsi-flexion?

A

agonist: tibialis anterior
antagonist: gastocnemius and soleus

39
Q

How do muscles create force?

A

muscles create force by contracting, using energy.

40
Q

What is an isotonic muscle contraction?

A

when a muscle changes length during its contraction.

This can occur concentrically and eccentrically.

41
Q

What is a concentric muscle contraction?

A

When a muscle shortens and produces tension.

The force pulls two bones closer together, causing joint movement.

42
Q

What is a eccentric muscle contraction?

A

A muscle contraction when a muscle lengthens producing tension. This resists fores, such as gravity, to control joint movement.

43
Q

What is an isometric muscle contraction?

A

When a muscle lengthens producing tension. This resists forces, such as gravity, to control joint movement.

triceps brachii

83
Q

Sporting example of elbow movement

A

In preparation phase, the biceps brachii will concentrically contract to flex the elbow, lowering the ball.

In the execution phase, the triceps brachii concentrically contracts to extend the elbow joint through a large range of motion to generate a large force to apply to the ball.

84
Q

Wrist joint type

A

condyloid joint

85

89
Q

Sporting example of wrist movement

A

basketball player concentrically contract the agonist, the wrist flexors, to flex the wrist as the ball is released in a jump shot.

This enables backspin to be put on the ball, causing the ball to ‘pop up’ from the back board rather than roll off.
