(London Daily Mail) Olympic champion Usain Bolt produced 50 times more energy than that of a speeding bullet during one of his record-breaking 100metre runs, scientists have revealed.
Physicists studying the secrets of Bolt’s success announced the findings after a detailed study of the Jamaican sprinter’s 100m performance during the 2009 World Championships in Berlin.
They discovered that he produced a remarkable 81.58kJ of energy – compared to just 1.6kJ of energy a bullet produces when it leaves the barrel of a 0.44 calibre Magnum handgun.
They also calculated that he reached a top speed of 27mph during the race.
But unlike a bullet – which can reach 1,000mph – Bolt’s huge 6ft 5ins frame meant more than 92 per cent of his energy was absorbed in battling air resistance.
