Walking is an example of isotonic type of contraction. These are contractions which will force the length of the muscle to change and cause movement.
The correct contraction of "it is" is "it's". Some people often get confused between "it's" and "its". It's is the contraction of it is, whereas its is possessive. For example, the cat is wagging its tail as it's walking.
Isometric Contraction :]
a example of a contraction is -It's-
The word it's is a contraction for the pronoun 'it' and the verb 'is'. Example use:It is Friday.It's Friday. (the contraction it's acts as the subject and the verb of the sentence)

isometric contraction
Peristalsis is the contraction of the digestive muscles. Peristalsis is the contractions that occur in the smooth muscles of the body.
isotonic contraction!
Isotonic contraction results in shortening of the muscle, leading to movement. In Isometric contraction, as the name implies, there is no change in length of the muscle. Thus, it can't lead to any movement. However, Isometric contraction adds or removes power from a movement, thus facilitating or retarding it. This, facilitation and retardation itself gives us a feeling of movement, for example walking, even in the total absence of actual movement i.e. walking. This feeling of movement induced by isometric contraction is known as Isometric movement. We use isometric movements in thinking and dreaming.
type of contraction of gastrocnemius muscle?
An isometric contraction builds tension but there is no joint movement.
The walls of blood vessels have smooth muscle, which allow contraction and dilation (for example, in response to temperature changes.
