It is made up of tibia and the talus bones.

What is dynamic balance movement?

It is where constant agonist-antagonist muscle contractions occur in order to matin a certain position or posture.

What is sustained force movement?

It is where continuous muscle contractions occur in order to keep moving a weight.

What is a ballistic movement?

It is where inertial movement exist after and explosive or quick, maximum-Force contraction. Here is pre-tensing of the muscle in the eccentric contraction so the muscle can contract concentrically with maximum speed and quickness

What is a guided movement?

It occurs when both agonist and the antagonist contract to control the movement.

What is the main responsibility of the endocrine system?

Main muscle responsible for movement; prime mover. Biceps brachili during biceps curl.

What are slow twitch fibers?

Muscles that help enable long-endurance feats such as distance running

What are the responsibility of assistant muscle? Give some examples.

Muscle that plays a secondary role in movement. Shoulder during a chest press.

What are muscle spindles

Sensory receptors within muscles -run parallel to muscles -sensitive to changes in muscle length and rate of length of change -regulate contraction of muscles via stretch reflex mechanism (prevents overstretching) Think: sensitive to lengthening, so opposite action = shorten and not over stretch
