Muscle Exercises: Types and Characteristics

Play an AI-generated podcast conversation about this lesson

What characterizes isotonic exercise?

Muscle contraction is only isometric

Muscle lengthening prevents tension development

Muscle contraction occurs against a constant or variable load (correct)

Muscle contraction without any change in length

What type of muscle contraction occurs during concentric exercise?

No movement around the joint

Relaxation of the muscle without tension

Overall shortening of the muscle as it generates tension (correct)

Lengthening of the muscle against resistance

Which of the following describes eccentric exercise?

The muscle shows no tension development

The muscle shortens while controlling motion

The muscle remains static with no movement

The muscle lengthens while developing tension (correct)
