Autumn Taylor Isotonic Contractions


Isotonic means that a muscle has the same tone throughout its movement. In other words, the muscle maintains tone and never gets saggy while shortening. To imagine this type of contraction you can think of lifting weights. If you were to bend your arm, so that your forearm flexed, the muscle in your forearm would be shortened by an external force (yourself) instead of an internal force from your body. Description

Isotonic Contractions:

Fitness experts point out that isotonic exercise often includes two specific kinds of training. These are called concentric and eccentric muscle contraction. Concentric contraction is when the muscle is moving weights upward and actively manipulating the resistance. Eccentric contraction is when the muscles are working passively, for example, when lowering weight along with gravity, or simply holding onto a resistance load and managing it, rather than pushing it or pulling it through a range of motion.

Relation To Exercise and Fitness:

Isotonic Exercise is useful in that it not only helps participants bulk up but provides specific muscle responses that will be useful in a range of athletic and recreational activities. It also does not require extensive equipment. You can use portable items such as dumbbells, kettle bells, medicine balls and other similar tools. This can also be seen as resistance training. This helps strengthen the muscles in several ways. Relation To Exercise and Fitness
