Question

Based on what you have learned in this unit, what type of muscle contraction do you think you experience most frequently throughout your day? How about when you work out? Define the type of muscle contraction that you experience most throughout your day and the one that you experience most when working out. Give examples to support your answer.

Answer 1

Answer:

Throughout a normal day I will have isometric contractions, but while I’m working out I will have isotonic contractions. An isometric contraction is when the muscle contracts, generating energy without changing the length of the muscle. While an isotonic contraction is when the muscle contracts and generates force while changing the length.

Hope this helps !

Answer 2

The type of muscle contraction I experience most often throughout the day is skeletal muscle contraction.

How does skeletal muscle contraction occur?

Skeletal muscle contraction occurs with the action of nerve impulses, releasing calcium ions that will act with ATP molecules in the movement of myofibril filaments. Skeletal muscle is responsible for the movements of the vertebrate body.

With this information, we can conclude that the type of muscle contraction that we use the most is the skeletal muscle contraction, because we are moved all the time.
