Isometric vs Isotonic Exercisesas
- Isometric exercises are when the muscle contracts without changing in length, like when you are flexing. An example of this type of exercise would be wall sits or planking.
- Isotonic exercises are when the muscle changes in length. there are 2 types of isotonic movements:
a. Concentric: this is when the muscle is shortening. Example, the upward motion when you do a bicep curl.
b. Eccentric: this is when the muscle is lengthening. Example, moving your arm back to straight from the bicep curl.
Isometric exercises are less stressful than isotonic exercises, so when individuals are recovering from an injury, they should start with isometric exercises and gradually move on the isotonic exercises.
