How does skeleton steering work?
Steering or braking mechanisms are absolutely prohibited on sleds, which are made of metal and can can weigh up to 95lbs, so sliders move their bodies ever so slightly to strategically navigate the course. The sleds are often customized to fit the sliders' frames, but beyond that, it's all about keeping the body as aerodynamic as possible, shifting weight in the knees and shoulders (and occasionally using the feet to push into turns). However, the objective is generally to stay in control while steering as little as possible, since you don't want to chance slowing down even a little bit.
Skeleton runs typically finish in under a minute, but the whole ride is actually quite grueling on the body, so it can be tough for sliders to endure more than a couple runs a day. Considering sliders are sprinting for 30 yards, crouched, while pushing a super-heavy sled, then bouncing around like a rag doll, it's not difficult to understand why. Also, taking a tight turn at top speed can produce the effect of 5 G-forces on the body (for perspective, astronauts only experience 3 Gs during liftoff). As Matt Antoine, a member of this year's US Olympic skeleton team, described to The New York Times, "We compare it to a contact sport."
