In fact 400 W is the work done. Energy spent depends on the time taken to finish 100 m . The energy required for metabolic conversion plus energy required for conversion of cabohydrates to glucose to be used for running will give the total energy required. This depends on efforts taken for running like speed, accelaration and efficiancy of the lungs.
