Olympic speed skaters sprint around ice ovals at more than 65 km/h. Balancing on 1 mm-thick blades, they fight more than 60 kilograms of centrifugal force as they pump their arms around each corner. They spend countless hours perfecting the aerodynamic skating positions they maintain throughout races; even off the ice, these naturally strong skaters complete regimens involving weights, cables, and wide high-speed skating ‘treadmills’ to train for races that can be won by thousandths of a second.
‘Wait! So is this a hypothesis, a theory, or a fact?’
