How do champion skaters accomplish their extraordinary jumps and spins? Mind science is uncovering clues.

The latest World Determine Skating Championships produced thrilling outcomes, together with a 19-year-old American touchdown a quadruple axel and a 40-year-old pairs skater who grew to become the oldest lady to win a world determine skating championship. As a neuroscience reporter, I’ve questioned how the mind works when skaters leap, spin and transfer on the ice at whirlwind speeds. Right here’s what scientists have discovered:
When most of us step onto an ice rink, the slipping sensation kick-starts a sequence of mind indicators telling the physique to tilt ahead to keep away from falling. However repeated follow mutes that reflex for skaters like Ilia Malinin, the American who was the primary particular person to land a quadruple axel in competitors and whose 2024 World Championship free skate rating was the very best ever. In such high skaters, the mind accepts the slipping feeling and rewires connections within the cerebellum, an space linked to steadiness.
Mind scans of velocity skaters have supplied extra hints concerning the cerebellum. Research have discovered that components of the cerebellum are bigger in short-track velocity skaters than in non-skaters, particularly the appropriate aspect. That’s most likely as a result of the appropriate aspect is activated when a velocity skater balances on the appropriate foot to show left round curves within the monitor.
One other mind community helps skaters carry out intricate routines. The basal ganglia receives indicators from the motor cortex as skaters leap and twirl within the air. When skaters follow applications repeatedly, this community organizes actions into chunks and sequences, fostering faster recall and muscle reminiscence. In competitions, this helps skaters proceed their performances even after stumbles or falls.
That mind community’s exercise possible helps Nathan Chen, the 2022 Olympic champion in males’s determine skating, when he performs a quadruple lutz, one of the tough jumps. He begins skating backward, extending his proper leg. Pushing off on his proper foot, he crosses his ft whereas hovering upward after which rotates 4 instances within the air. Touchdown on the appropriate leg, he sweeps his left leg up behind for the end.
The brains of determine skaters suppress the sensation of dizziness after lightning-fast spins. Spinning causes fluid within the internal ear to slosh round. In most individuals, it retains sloshing for some time after the spinning stops, which causes dizziness as a result of the mind falsely assumes rotation is continuous. Skaters’ brains be taught to inform when the spin has really stopped, permitting them to take care of their steadiness.
The mind’s approach of adapting to rotational movement helps facilitate the extraordinary spins of skaters like Michelle Kwan, a five-time world champion identified for having the ability to spin in each instructions with out pausing. In a single efficiency, she did a left layback spin adopted by a proper camel spin together with her leg prolonged, after which whirled to the left once more with a sit spin that blossomed into an upright Y spin.
