Isometrics
Isometrics
Isometrics (/aɪsəˈmɛtrɪks/), derived from the Greek words 'isos' meaning equal and 'metron' meaning measure, is a type of strength training in which the joint angle and muscle length do not change during contraction. Isometrics are done in static positions, rather than being dynamic through a range of motion.
History
The concept of isometrics has been around for thousands of years, with evidence of its practice in ancient Greek and Egyptian societies. However, the term "isometrics" was first coined in the early 20th century by German physician Dr. Erich Albert Müller.
Types of Isometrics
There are three main types of isometric exercises: overcoming isometrics, yielding isometrics, and functional isometrics.
- Overcoming Isometrics: This involves pushing or pulling against an immovable object, such as a wall or a weight that is too heavy to lift.
- Yielding Isometrics: This involves holding a weight that could be moved in a static position until fatigue sets in.
- Functional Isometrics: This is a combination of the two previous types, where a movable weight is held in a static position for a period of time, then moved, and held again.
Benefits
Isometric exercises have been found to increase strength and stability, improve muscle tone, and enhance bone density. They can also be beneficial for injury rehabilitation and can be performed anywhere without the need for special equipment.
