Power
A study has revealed that the average energy output of a professional player over a season could power a house for 10 days.
Dr David James, from Sheffield Hallam University, was asked to produce a figure by the E.ON Energy Experience initiative. He looked at a player’s oxygen uptake and the ratio of low to high intensity work.
Players make more than 1,000 changes in activity over 90 minutes — altering their speed of movement every four to six seconds — and they cover ten to 12 kilometres, sprinting more than 2km.
He concluded that players produce 6,700 kilojoules, which equates to 1.86 kilowatt hours. If it were possible to convert that energy into electricity, over a full game, a player could light an average house for 90 minutes, run a television for 6½ hours and boil enough water for the squad to enjoy a half-time cuppa.
