As such, an isotonic contraction is one in which the muscle maintains the same tension as it shortens. Examples of activities that involve isotonic contractions include walking, running or lifting a light object. Isotonic contractions come in two varieties: concentric and eccentric. In a concentric contraction, the muscle shortens when its tension is greater than the force opposing it, such as your biceps does when performing an arm curl.

Isometric and isotonic contractions are types of muscle contractions that perform different functions, and this quiz and worksheet combination will help you test your understanding of the purposes.

In an eccentric contraction, the force is greater than the muscle tension, causing the muscle to elongate; this happens when going down stairs or sitting down in a chair, as the effects of gravity add to the opposing force. When undertaking a strength training or general fitness regimen, most of the exercises you perform will be isotonic in nature, targeting the body's major muscle groups. In addition to weight training, these include exercises such as walking, cycling and performing calisthenics. This also includes the operation of many of the fitness devices designed for use in the home, such as ellipticals and steppers. After a workout, it is important to allow the targeted muscle group a day or two to recover before performing the same set of exercises again.
