Question

How many different types of contraction is skeletal muscle capable of making?

Answer 1

There are four different types of skeletal muscle contractions: 1. Concentric (isotonic) contractions: In this contraction type, the muscle actively shortening. The raising of a dumbbell during biceps curl exercise is an example of concentric contractions. 2. Eccentric Contractions: During normal daily activity our muscles are often active while they are lengthening. Walking is an example of eccentric contractions. 3. Isometric Contractions: The muscle is activated at a fixed length. Holding an object would be an example of this type of contractions. 4. Passive Stretch: The muscle is being lengthened during in a passive state. An example of this type is the pull one feels in their hamstrings while touching their toes.

Answer 2

There are 3 kinds of contraction in skeletal muscle:
Concentric contraction: The muscle in this contraction will gives force more than the load gives. This will make the muscle shorten as it pulling the load.

Eccentric contraction: In this contraction, the force given by muscle is not enough to pull the load. This causes the load pulling the muscle instead. So the muscle will be lengthened as the load moving away.

Isometric contraction: In this contraction, the length of the muscle will be kept same by adjusting the force given to be equal to the force needed.
