Muscles change through a process called hypertrophy, which involves an increase in the size of muscle fibers by adding more proteins and filaments. This can occur through strength training exercises that create micro-tears in the muscle fibers, prompting the body to repair and rebuild them to be stronger and larger. Additionally, muscle size can also be influenced by factors such as nutrition, hormone levels, and genetics.
Isotonic contractions involve a change in muscle length and joint movement, while isometric contractions do not result in joint movement or change in muscle length. Isotonic contractions are further classified into concentric (muscle shortens) and eccentric (muscle lengthens) contractions. Isometric contractions involve the muscle producing tension without changing its length.
The other fundamental requirement for movement is the application of force, such as muscle contraction, to enable the change in position. Both a change in position and the application of force are necessary for an object or organism to move from one place to another.
No, depolarization refers to the change in electrical charge within a cell, specifically during the initiation of an action potential. Contraction refers to the shortening or tightening of muscle fibers, which is a separate physiological process that can be triggered by depolarization in muscle cells.
Isometric exercise involves pushing against a fixed surface. This type of exercise involves static contractions where the muscle length does not change during the movement. It is effective for building strength and increasing muscle endurance.
The thick filaments (made of myosin) do not change length during shortening of the sarcomere. They slide past the thin filaments (made of actin) to generate muscle contraction.
its a muscle
A muscle cell is a cell which can change length
A muscle that contracts shortens whereas a muscle that relaxes lengthens.
They measure the rate of change of length of a muscle.
No, the length of the muscle fibers does not change. In isotonic movements is when the length changes.
The muscle length will not change during a contraction.
No, fat cannot turn into muscle and muscle cannot turn into fat.
muscle relaxation can help you!
isometric contractions
muscle weighs more than fat. your weight may not change because you are gaining muscle mass, which weighs more.

muscle cells change and can move
