ATP - Adenosine triphosphate
When the muscle contracts, the tendon pulls on the bone to create movement. The tendon is the connective tissue that attaches the muscle to the bone, so when the muscle contracts, it exerts force on the tendon, which in turn moves the bone.
When a muscle contracts, it pulls with a force generated by the muscle fibers contracting and shortening.
Eccentric contraction (isotonic)
Depends on the total number of individual muscle fibers that have been stimulated.
ATP is used in muscle contraction to provide energy for the movement of muscle fibers. When a muscle contracts, ATP is broken down into ADP and phosphate, releasing energy that powers the movement of the muscle fibers. This energy is needed for the myosin heads to bind to actin filaments and generate the force required for muscle contraction.
When a muscle contracts, the physiological process occurring within the body is the shortening of muscle fibers, which results in the generation of force and movement.
I think that gravity exerts an attractive force that gives the material potential energy.
Passive tension is the force exerted on a muscle when it is stretched, while active tension is the force generated by the muscle when it contracts.
It exerts magnetic energy to push or pull an object
No! It is isotonic. But if the muscle contracts and the fibers do not shorten because the load is greater than the force applied to it, it is isometric.
An example of an internal force is the tension created within a muscle when it contracts to move a body part.
