The excitation, contraction, and relaxation of skeletal muscle
require the use of ATP. Because only limited stores of ATP are
immediately available in muscle tissue, ATP must be continually
supplied if contractile activity is to continue.
Depending on the type of movement or exercise, one or more
pathways can be used to provide the most efficient way of supplying
the ATP.

energy needs of athletes
Skeletal muscles, which move bones, consist of cells fused into
long fibers. These muscle fibers can increase in size when
contracted, which is what happens as a result of some exercise.

It starts at a large scale, showing the muscles of a human upper
arm, and then gradually zooms in to smaller and smaller levels,...
