When muscles increase in size, they become stronger and more efficient.
What is muscles?
Skeletal, smooth, or cardiac muscle make up the muscular system, an organ system. It allows for body movement, supports posture, and moves blood throughout the body. Although some muscles, like the heart muscle, are capable of complete autonomy, the neurological system controls the muscular systems in vertebrates. It creates the musculoskeletal system, which controls how the body moves in humans, along with the skeletal system. Skeletal muscle, cardiac and heart muscle, or smooth (non-striated) muscle are the three main categories of muscle. muscles give the body movement, balance, posture, strength, and heat for keeping warm.
The muscle fibers become thicker and longer, allowing them to contract more forcefully. The number of muscle fibers also increases, and the muscle cells become more efficient at using nutrients and oxygen to produce energy. Additionally, the nerve cells that control the muscles become better at sending signals to the muscle, allowing for improved coordination and control.
