What else can I help you with?
What is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
Diferentiate between isotonic and esometric excises?
Isotonic exercises involve movement of a joint and a change in the length of the muscle during contraction, such as bicep curls. Isometric exercises involve holding a position without joint movement, with the muscle remaining at a constant length, such as planks.
What is isotonic and iso inertial contraction?
Isoinertial exercises are those that maintain a constant inertia = mass. A weight is placed on an extremity (arm or leg) and the extremity is put through a range or motion (or pattern of movement of that extremity). This range of motion can change direction but the force on the extremity doesn't change. An example of this is the yo-yo, it changes direction at the bottom, but the mass of the yo-yo stays the same. Isoinertial exercises strengthen both the muscle being targeted as well as the synergistic (helper) muscles as well. This type of exercise also helps to strengthen ligaments and tendons throughout the range of motion. Isoinertial exercises are not to be confused with (although hard not to) isotonic exercises. Isotonic exercises have a constant muscle force which often involves a constant resistance such as a free weight (dumbbell etc.).
What is an Isotonic Contractions?
Isotonic contractions. This happens when the muscle shortens as it contracts
What is an example of a isotonic exercise?
An example of an isotonic exercise is a bicep curl, where a person lifts a weight by flexing their elbow, causing the muscle to shorten and lengthen throughout the movement. This type of exercise involves a constant load and allows for muscle contraction against resistance, which helps build strength and endurance. Other examples include squats and bench presses.
What is the difference between isotonic and isometric contractions?
An Isotonic muscle contraction is a muscle contraction that makes your limbs move whereas an Isometric contraction is a muscle contraction where the limbs stay static
The muscle decreases in muscle length during contraction but tension is the same?
Isotonic contraction
What type of muscle contraction is involved in warming up?
isotonic contraction!
A contraction in which the muscle shortens and work is done?
B. isotonic contraction
What are the differences between isometric, isotonic, and isokinetic exercises in terms of muscle contraction and movement?
Isometric exercises involve muscle contraction without movement, isotonic exercises involve muscle contraction with movement, and isokinetic exercises involve muscle contraction at a constant speed.
Is concentric isotonic contraction is defined as tension developing in the muscle as it shorten?
That is correct, the muscle shortens as it contracts. E.g. A bicep curl, the bicep muscle as you lift the wight up is Isotonic contraction. :)
What contraction that shortens the muscle but does not increase tension is called?
It is called concentric isotonic contraction.
A contraction in which a muscle exerts force lengthens and is overcome by a resistance?
Eccentric contraction (isotonic)
A contraction that causes a muscle to lengthen rather than shorten is called?
An eccentric contraction is one that causes a muscle to lengthen.
What is an Activity that combines muscle contraction with repeated movement?
An activity that combines muscle contraction with repeated movement is Isotonic execrise
In an isotonic contraction the muscle?
shortens while maintaining constant tension.
Does muscle tension remain constant during isotonic contraction?
Yes.
