KEY POINTS:
The energy generated by British soccer dynamo Wayne Rooney as he sprints around the pitch during a match is enough to boil water for 16 cups of tea, according to research published yesterday.
David James, of Sheffield Hallam University's Centre for Sports Exercise Sciences, calculated that the 21-year-old Manchester United and England striker produced 6700 kilojoules of energy, equivalent to 1.86 kilowatt/hours of electricity.
This was also enough to light an average house for 90 minutes or run a standard television for six and a half hours.
