Question

Quizplus · Accepted Answer

In an isotonic contraction, the tension within the muscle remains constant but the length changes, leading to movement. This is demonstrated in activities such as walking, running, and lifting weights. A tonic contraction refers to a sustained contraction without movement, an isometric contraction involves tension without a change in length, and a tetanic contraction refers to sustained and rapid contractions.
