Abstract: An investigation into the work involved in sprint running is made by a method of cinematographic analysis. The runners are photographed as they pass behind a lattice which serves as a system of coördinance, the timing being accomplished by means of a series of dropping balls. As a result of this analysis, it has been possible to determine the amount of power required to accomplish the various component motions of the runner, and to separate these from the energy required to overcome gravity, wind resistance, and frictional contact with the ground.
