56
Q

Define and name phases of the muscle action: Force is produced, muscle tension is developed, and movement occurs through a given range of motion.

A

Isotonic.

Eccentric & Concentric phases.

57
Q

Define and give example of the muscle action: Moving in the same direction as the resistance. Decelerates or reduces force.

A

Eccentric.

Ex: Landing from a jump, lowering a weight during resistance exercise.

58

Define and give an example of the muscle action: The speed of movement is fixed, and resistance varies with the force exerted Requires sophisticated training equipment often seen in rehabilitation or exercise physiology labs.

A

Isokinetic.

The harder an individual pushes or pulls, the more resistance they feel.

Unsure of examples - fancy equipment must be used.

65
Q

Muscle fibers that contain a greater amount of capillaries, mitochondria, and myoglobin. These fibers are usually found to have a higher endurance capacity than the other type of fibers.

Slow twitch fibers (type I)

66
Q

Muscles that assist prime movers during functional movement patterns.

A

Synergist

67
Q
