Muscle physiology is a branch of biology that focuses on the study of muscles and their functions within the human body. This field explores the structure, function, and properties of muscles, such as their contractile capabilities and their role in movement, stability, and force generation. Researchers in muscle physiology investigate how muscles respond to various stimuli, such as exercise, injury, and disease, and how they adapt and change over time. This research area is important for understanding the mechanisms behind muscle performance, muscle growth and regeneration, as well as for developing treatments for muscle-related disorders and injuries.
