Question

Isometric muscle contraction is defined as a muscle shortening along its long axis as it generates force.

a) True
b) False

Answer 1

Isometric muscle contraction is a type of muscle contraction where the tension increases, but the muscle length remains the same. It is active in maintaining posture and stability.

Step-by-step explanation:

An isometric muscle contraction is defined as a contraction where the tension in the muscle increases, but the length of the muscle remains the same. This means that there is no movement at the joint. Isometric contractions are active in maintaining posture and bone and joint stability. An example of an isometric contraction is when you try to lift a weight that is too heavy and you cannot move it, but you can feel the tension in your muscles.
