Question

The most common type of muscle contraction encountered with most exercises is ________, meaning the contraction proceeds at a consistent muscle tension while the body part moves through its range of motion. a. eccentric b. isotonic c. isokinetic d. isometric

Answer 1

Answer:

Option-B

Explanation:

Muscle contraction refers to the generation of tension in the muscle caused by the actin and myosin filaments and can be categorized by the length of the muscle during the muscle contraction.

The isotonic contractions are a type of contraction during which a constant or regular muscle tension in the muscle is maintained as the length of the muscle changes. The tension is maintained when the force on the contraction exceeds the total load on the muscle.

Thus, Option-B is the correct answer.

Answer 2

Answer:

The correct answer is-b. isotonic

Explanation:

Isotonic contraction is the contraction in which the tension remains the same but the wrist muscle length changes which results in the movement of a body part. Two types of isotonic contractions are Concentric contractions and Eccentric contractions.

In concentric contractions, muscle contract and become short and Eccentric contractions is opposite to concentric contractions in which muscle lengthens. Isotonic contraction is the most common type of muscle contraction which is encountered within exercise. Thereofore the correct answer is b. isotonic.
