ATP stores energy that can be used in a coupled biological reaction that requires energy. To do this ATP loses the last phosphate group converting the molecule to ADP & P. The phosphate group is often transferred to some reactant that allows it to carry out some biological process and in this case, allow the filaments used in muscle contraction to change their position, resulting in a shortening of the fibers contraction).
