Detailed explanation-1: -Explanation: There are two types of muscle contractions : Isometric and Isotonic. Here we can see pushing against a wall is not an example of isotonic contraction.
Detailed explanation-2: -isometric, isotonic. Pushing against a wall involves the muscle contracting in a way that doesn’t change the muscle’s length. This is known as an isometric contraction.
Detailed explanation-3: -There are 2 types of isotonic contractions: concentric and eccentric. In a concentric contraction, the muscle tension rises to meet the resistance then remains stable as the muscle shortens. During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.
Detailed explanation-4: -That means your muscles maintain the same tension throughout the exercise. Examples of isotonic exercise include squats, stair climbing, bicep curls and push-ups.
