Staggered start stance in skeleton: foot position, grip and rocking for the start, what biomechanics shows, and where you practise only with a coach.
The honest answer: The staggered start stance is the moment before the first step. You stand with the rear foot on the starting block, the front foot is placed on the ice, and one hand holds the sled at the saddle. The stance resembles a sprint start in athletics. It is described as the "block phase": the athlete stabilises the sled flat on the ice, sets the feet in a staggered stance, rear foot on the block, front on the ice, and rocks the sled back and forth with the hips to break its inertia [1].
Why it matters: in the skeleton start, pushing and jumping on supply all of the sled's kinetic energy [2]. The best are through 50 metres in about five seconds, at more than 40 km/h [3]. Without a good start, usually within a tenth of a second of the fastest, winning is almost impossible according to the British federation [3].
And here is the part almost nobody tells you up front: science does not say how far apart the feet should be exactly. A study with 20 athletes of the Chinese national team found: the maximum horizontal force (about 827 newtons) and the impulse were not related to the distance between front and rear foot. The left-to-right width should match the hip width, otherwise the direction of the force does not fit [2]. Everything else below is coaching practice and carries no source number.
Realistically: this is an intermediate skill. You build it first on dry ground and in sprinting, not on the ice track.
Place the rear foot at the block, the front foot stands in front of you on the ground. The width of the feet is guided by the hip width [2]. One hand grips the saddle, the gaze goes forward and down.
Milestone: You stand calmly for ten seconds without wobbling, with both feet in the right place.
Hold the sled flat with one hand. The description of the block phase names exactly that: the sled is stabilised flat on the ice [1].
Milestone: The sled stays in the starting position without tipping or drifting.
Rock the sled back and forth with the hips to break the inertia. This can happen several times [1]. You need rhythm, not force.
Milestone: Two to three clean rocking movements, each time in the same rhythm.
From the last rock you go into the drive phase: the hip extends, you push against the block and accelerate the sled. The phase ends when the shin is vertical in the swing phase [1].
Milestone: The first step is powerful, but the sled stays in line.
Have the stance filmed. Ask: does the foot width fit the hips? Does the force run in the direction of travel? The paper gives a hint: hip position is related to knee angle [2].
Milestone: You and your coach have fixed a stance you can repeat.
Film yourself on the dry track from the side and draw two lines: the line from the rear foot to the saddle and the one from the front foot. If the lines arrange themselves the same way at every start, you have a reproducible stance. That is coaching practice. That the front-to-back distance plays no role for force according to the study [2] means: repeatability counts more than the exact value.
The rear foot stands at the starting block, the front on the ice, one hand grips the saddle and stabilises the sled, similar to a sprint start [1]. Then the athlete rocks the sled with the hips [1].
Left to right about hip width [2]. For the front-to-back distance a study with 20 national team athletes found no relation to force or impulse [2]. A fixed value cannot be derived from it.
In the study the average start distance was 18.45 metres in 12.2 steps [2]. Competitions have their own measuring points, for example 50 metres [3].
Parts of it, such as standing, sprinting and hip movement in dry training with a coach. The ice and the track stay reserved for the club group.
Yes, on ice spikes give the grip you need for full force [3]. For dry training you use suitable sprint shoes.
