Muscle Science

Muscle science explores how our muscles work and respond to various activities. Muscles are made of fibers that contract to produce movement. They require energy, primarily from nutrients like glucose and fatty acids, which are supplied through blood. Exercise encourages muscle growth and strength by causing small tears in the fibers, which then repair and adapt to become stronger. Types of muscles include skeletal (voluntary movement), smooth (involuntary functions like digestion), and cardiac (the heart). Understanding muscle science helps us improve fitness, rehabilitation, and overall health through targeted physical activities and nutrition.
