Why are skeletal muscles not depleted of energy during intense exercise?

ATP is a universal carrier of energy in a form easily accessible for different reactions in the cell. Its hydrolysis to ADP and Pi (inorganic phosphate) drives processes that cannot occur spontaneously and require energy, for instance

Superthin muscle filaments: evolution and function of titin in skeletal muscle

The mechanisms by which muscle converts chemical to mechanical energy, allowing animal movement, defied explanation for decades. Following the development of the electron microscope and mechanisms of tissue fixation, the ultrastructure of muscle was finally described. Thus
