Blade runners: the facts

WHY OSCAR WAS WRONG

Oliveira’s new blades made him 181cm tall, some 3.5cm under his maximum height. Pistorius stands 184cm tall in his blades

Pistorius in fact took fewer strides than Oliveira and covered 20cm further per step, negating his claims the Brazilian’s greater height meant he needed fewer strides

The time run by Oliveira and branded “ridiculous” by Pistorius was 0.15 slower than the South African’s world record

Blades are made of carbon fibre and fit snugly to the athlete’s lower limb

Maximum length of blades is calculated using athlete’s upper-body measurements

Blade length just one of three factors in pace, say experts, with force applied to ground and speed of leg movement
