Question

While exercising on a multigym, the type of muscular contraction that occurs is(A) Isotonic(B) Isometric(C) Isokinetic(D) Eccentric​

Answer 1

Answer:

A) ISOTONIC

Explanation:

Isotonic exercise: Exercise when a contracting muscle shortens against a constant load, as when lifting a weight. Isotonic exercise is one method of muscular exercise. In contrast, isometric exercise is when muscular contractions occur without movement of the involved parts of the body.

Answer 2

The correct option is (A) isotonic.

• Concentric or isotonic contractions are terms used to describe muscular shortening during a contraction. When the muscle generates a force larger than the constant stress the muscle is under the muscle contracts in this manner.
• Concentric and eccentric contractions are the two main varieties of isotonic contractions.
• In concentric contraction the muscle is being pulled by an external force, which is less than the force the muscle is producing as it contracts shorter. The traditional biceps curl, which is actually auxotonic, lacks the benefit since the resistance changes throughout the exercise.
• There are two key characteristics of eccentric contractions to be aware of. First off, compared to the muscle's greatest ability to generate tetanic tension the absolute tensions attained can be extremely high. Second, the lengthening velocity largely has no effect on the absolute tension.
• Eccentric contraction is specifically linked to muscle injury and pain. Exercises using eccentric contractions have a smaller effect on muscle strength than activities involving concentric contractions.
