difference between isotonic and icomitric means in Hindi yar hindi mai bta do plz mera exam Hai
Answers
Answer:
The word “isotonic” is derived from two Greek words: “iso,” meaning “same,” and “tonikos,” meaning tension. 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. 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.
Isometric
“Isometric” means “same length,” and in contractions of this variety, the muscle does not shorten and its tension never exceeds the opposing force. Examples of isometric exercises include holding a weight in place above the ground or pushing against a stationary object. While the entire muscle does not change length during an isometric contraction, the individual muscle fibers will shorten. As such, isometric exercises can help to strengthen a muscle.
Isokinetic
A third type of contraction is “isokinetic,” or “same motion.” In these contractions, the muscle shortens at a consistent rate throughout the motion. Exercises involving isokinetic contractions are often used in rehabilitation settings, and generally require the use of special equipment capable of providing consistent resistance and velocity throughout the activity.
Answer:
Isotonic contractions generate force by changing the length of the muscle and can be concentric contractions or eccentric contractions. A concentric contraction causes muscles to shorten, thereby generating force. ... Isometric contractions generate force without changing the length of the muscle.
