A contraction in which there is no change in muscle length but there is a great increase in muscle tension is?
isometric contractions
The muscle decreases in muscle length during contraction but tension is the same?
Isotonic contraction
What is A contraction in which the muscle changes in length with the same tension applied to it?
Isotonic ContractionIsotonic Contraction
The type of contraction in which there is a change in the length of a muscle but no change in its tension?
Isotonic is the word you're looking for. Isotonic means the tension remains the same, but the length can change. Isometric means the length remains the same, but the tension can change.
If you change the length of the string will it make the frequency increase or decrease?
increase the length of the string means decrease the tension in the string, therefore as the tension decreases the frequency will drop due to loosen of the string.
What happens If a muscle is applied to a load that exceeds the muscle's maximum tension?
The muscle length will not change during a contraction.
What is static muscle contraction?
Contraction in which opposing muscles contract against each other and prevent movement. Fixation action of a muscle in a static contraction is termed isometric, because it develops tension without changing length.
What is the contract antagonist-relax method of stretching?
stretching that facilitates and increase in muscle length through isometric contraction
Isometric contractions - exercise?
What is isometric exexrcises
Which wave length is larger atrial contraction or ventricular contraction?
the ventricular contraction wave is larger
Is lifting a dumbell isotonic or isometric?
Lifting a dumbbell is a isotonic contractins because the tension remains unchanged and the muscle's length changes. Any lifting of objects is considered an isotonic contraction.
How does preload affect the stroke volume?
Preload refers to the degree of stretch of cardiac muscle cells before contraction. These muscles exhibit a length-tension relationship. When the cardiac muscle cells are at rest, they are shorter than their optimal length. The most important factor affecting the stretching of cardiac muscles is the venous return, that is, the amount of blood returning back to the heart. Slow heartbeat and exercise can increase the venous return. This will lead to the stretching of the ventricles and it will hence increase the contraction force.As reflected by the Frank-Starling Law, the stroke volume increases with the end diastolic volume. The greater filling volume will lead to the heart to stretch more and this will increase its force of contraction.
