The word "isotonic exercise" is spelled with the prefix "iso-" meaning "equal" or "same", and the combining form "-tonic" meaning "tension, pressure or tone". The final element "-ic" signifies the word is an adjective. This exercise involves performing an action with equal tension throughout the range of motion. In IPA phonetic transcription, "isotonic exercise" is pronounced /ˌaɪsoʊˈtɑnɪk ˈɛksɜrsaɪz/, with stress on the second syllable of "isotonic" and on the first syllable of "exercise".
Isotonic exercise refers to a type of physical activity or movement that involves the contraction and relaxation of muscles while maintaining a constant tension against a resistance. It is a form of exercise in which the muscle length changes as it contracts, resulting in a visible movement.
In isotonic exercises, the resistance against which the muscles work remains constant throughout the entire range of motion. This resistance can be provided by using weights, exercise machines, resistance bands, or even the body's own weight. The goal of isotonic exercise is to improve muscular strength, endurance, and tone.
During isotonic exercise, the muscles undergo both concentric and eccentric contractions. Concentric contractions occur when the muscle shortens as it contracts, while eccentric contractions occur when the muscle lengthens as it contracts. This dynamic movement helps to engage different muscle fibers, leading to overall muscle development and increased muscle mass.
Isotonic exercise offers numerous benefits such as increased cardiovascular fitness, improved flexibility, enhanced bone density, increased metabolism, and better overall muscular strength and endurance. It can also be tailored to target specific muscle groups or achieve specific fitness goals. Examples of isotonic exercises include bicep curls, squats, lunges, push-ups, and deadlifts.
Overall, isotonic exercise provides a comprehensive approach to physical fitness by combining muscle building, endurance training, and flexibility. Whether performed for general fitness, rehabilitation purposes, or sports-specific training, isotonic exercises help individuals improve their overall functional strength and enhance their physical performance.
The word "isotonic" originates from the Greek words "iso", meaning "equal", and "tonos", meaning "tension" or "force". In the context of exercise, the term "isotonic" refers to a type of muscle contraction where there is equal tension or force maintained throughout the exercise movement. Isotonic exercises are characterized by the exertion of a constant force against a movable resistance, which leads to muscle contraction, movement, and joint involvement.
