How do muscles produce mechanical energy?

Best Answer: Muscles use chemical and electrical energy to produce mechanical work through a complex process. Below is a brief and simple explanation. Muscles produce mechanical work through a process called contraction. This occurs when the muscle fibers pull in or shorten. read more

Muscles transform the chemical energy into mechanical when they contract. Oxidation of fats and carbohydrates and anaerobic chemical reactions are both used to move muscles. These chemical reactions produce ATP. Muscles use ATP to move the myosin heads "against" actin which causes the muscle to contract. read more
