Wei’s experience, watching a race means “you just watch these guys sprint and disappear into a tunnel and they’re gone.” He added, “There’s no way to know exactly what the athlete is doing along the entire track, and to get data off it.”īut in a race where victory margins are typically a few hundredths of a second, it’s crucial for athletes to understand the aerodynamic forces slowing their slide, in order to minimize them.
The track at the Yanqing National Sliding Center in Beijing, also called “the Snow Dragon,” has a 360-degree turn. This exclusivity creates economic and environmental barriers for sliders from other countries hoping to train, let alone make it to the Olympics.Īnd the tracks are often serpentine, winding like roller coasters, making it difficult to keep a continuous eye on an athlete as they barrel down the track. The International Bobsleigh & Skeleton Federation lists just 17 tracks around the world, all located in the Northern Hemisphere. It’s not easy to get to a track for practice.
In skeleton, athletes experience the elements face-first, all while tucking their heads down to remain streamlined, chins hovering just inches above the hard ice and eyes straining upward to visualize the track. In luge, athletes wear a neck strap to hold up their head under high G-forces bobsled athletes, seated, are enveloped by their vehicle. The sliding is physically brutal: Athletes endure four to five G-forces of pressure around turns and must withstand the rattling vibrations of the track. But scientists know far less about the mechanics of the more terrifying phase of skeleton. Scientists have investigated the ideal number of steps, the ideal step length and frequency and even the ideal angles of the hips, knees, ankles and thighs during the running phase. Much of the sparse, nonproprietary research on skeleton concerns the sprinting phase of the sport, where athletes run to generate velocity while pushing their sled across a short distance before jumping aboard. “And all the drag forces are slowing you down.” “It’s gravity that pulls you down the track,” said Timothy Wei, a mechanical engineer with expertise in fluid dynamics at Northwestern University, who works with skeleton athletes. The physics of the sliding sports - skeleton, bobsled and luge - are simple. The sport appeared in the Olympics in 19, when the games were held in St. And although the name “skeleton” fits a sport that would seem to invite death head-on, it has murky origins it may have arisen from a poorly Anglicized Norwegian word or the steel sled’s sparse, skeletal appearance. Moritz, Switzerland, when recreational sledders began careening down headfirst. The sport started in the late 19th century on the Cresta Run, an icy outdoor track used for sledding in St. Skeleton was invented on a bit of a whim, according to the International Bobsleigh & Skeleton Federation. “There are even times when I just use my eyes,” Katie Tannenbaum, a skeleton athlete from the Virgin Islands, told The Times in 2018.
The slightest twitch can help or hurt by altering the athlete’s aerodynamics in ways that athletes, coaches and researchers are still trying to decode. But skeleton racers can guide themselves with only the subtlest of shoulder shrugs or foot taps.
Lugers steer by flexing their calf muscles and gripping the sled’s handles.
Face vs skeleton drivers#
Bobsled drivers steer by pulling on two pieces of rope attached to a steering bolt. The other sliding sports provide clearer paths to victory. Yet for all the modernity of skeleton - it was reintroduced to the Winter Olympics lineup only in 2002 - scientists are still deeply puzzled by it. Life was hard enough without central heating there was no reason to hurtle face-first down a frozen chute on a brakeless sled. The sport called skeleton has no such hallowed origins in the practical transport of humans or goods, despite technically taking place on a sled. And the First Peoples in Canada used toboggans to transport goods. Thousands of years ago in Northern Europe, people strapped animal bones to their feet to skate around on ice. Skiing may have first emerged 10,000 years ago in Altay, China, and the Indigenous Sámi word for skiing (“ čuoigat”) is estimated to be 6,000 to 8,000 years old. Many Winter Olympic sports have ancient origins, dating to times when humans invented new ways of getting around in the harsh, white wilderness.
