Neural impulses and chemical reactions. If you really want to know the physilogical processes involved I suggest you pick yourself up a university grade medical/exercise science text book and start reading about energy systems, nueral pathways and processes, the sliding filament theory and the masses of information this will lead you too. Enjoy!

What is the type of contraction in which the muscle fibers produce increased tension but does not shorten?
An isometric contraction builds tension but there is no joint movement.
what's an isometric contraction?
An isometric contraction is when the muscle does not shorten and no movement results.
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
What is muscle contraction without muscle shortening is what kind of contraction?
Isometric contraction. This type of contraction occurs when the muscle generates tension without changing its length, such as when holding a weight in a fixed position.
What type of contraction in which the muscle fibers do not shorten are called?
If the muscle can not shorten because the muscle is trying to move a load that is greater than the force, then the contraction is isometric.
If a muscle contracts and its fibers shorten is the contraction isometric?
No, if a muscle contracts and its fibers shorten, the contraction is considered isotonic, not isometric. Isometric contractions occur when the muscle generates tension without changing its length.
Pushing against a locked door is an example of what type of a muscle contraction?
Isometric Contraction :]
Is it true or false that during isometric contraction the energy used appears as movement?
False. During isometric contraction, there is no visible movement because the muscle is generating force without changing in length. The energy used in isometric contraction is primarily used to maintain muscle tension and stability.
A contraction in which a skeletal muscle does not shorten but its tension increases is called isometric?
Yes, that's correct. In an isometric contraction, the muscle does not change in length but generates tension. This type of contraction can be useful for maintaining posture and stability in the body.
A contraction in which there is no change in muscle length but there is a great increase in muscle tension is?
isometric contractions
How do isometric and isotonic muscles differ?
Isometrics can be given at different angles within a joint range whereas statics are given at beginning of range
What is it called when a muscle applies force without moving?
isometric contraction
