How do you build a combination spin? Link at least two basic positions with two revolutions each: rules, build-up, mistakes and safety hints for skaters.
The honest answer first: a combination spin links at least two different basic positions in one rotation, and in the ISU rulebook each of these positions needs at least two revolutions. The positions may lie anywhere within the spin [1]. The three basic positions are camel (knee of the free leg higher than the hip), sit (thigh of the skating leg at least parallel to the ice) and upright (all other upright positions) [1].
Further rules from the handbook: the revolutions in non-basic positions count towards the total number of revolutions, and changing into a non-basic position does not count as a change of position [1]. In the free skating programme of competitions, a combination spin needs at least ten revolutions in total from entry to exit; if this minimum is missing, the judges reduce their grade [1].
Honestly: the combination spin is not a required element of the Learn to Skate USA adult levels 1 to 6. It builds on the sit and camel spins. The rulebook provides definitions but no learning methodology; the hints below are practical experience.
Choose two different basic positions that you master securely, for example upright and sit, or camel and sit [1]. You add a third position only later. Milestone: you manage both positions individually with three revolutions each.
Plan at which point of the rotation you change position. The change happens on the same foot, in one movement, without shifting weight to the other foot. Practise the transition first holding on to the boards without rotating.
Begin with the first position and count at least two revolutions [1]. More revolutions are fine; fewer do not count as a position in the rules.
Then change calmly into the second position and hold it for at least two revolutions [1]. Make sure the centre does not travel. Milestone: you manage both positions in one rotation, each with at least two revolutions.
Increase the total number of revolutions step by step towards ten, the competition minimum for the free skate [1]. This is a benchmark from the rulebook, not a must for your recreational level.
Think of an image: "I draw a spiral in one movement". In a review of 12 studies with 566 participants, an external focus was on average more effective than an internal one for skill acquisition, although the studies were small and the result should be read with caution [3].
Plan a short, fixed session for the combination (rule of thumb, not a study): five minutes of upright spins to warm up, then five repetitions of each single position, then five attempts of the combination. Pause after every series, because dizziness is a warning signal. A phone video from the side shows whether the positions reach the required height and whether the centre stays stable.
Count three numbers in every attempt: revolutions in position A, revolutions in position B and the total (rule of thumb, not a study). If A and B each reach at least two and the total grows without the centre travelling, you are on the right track. Write down the three numbers after the session; that shows where it sticks: in the transition or in the depth.
This guide explains and motivates; it does not replace supervised training. Long rotations take away your balance and orientation; dizziness and nausea are reasons to stop immediately. Practise only in a free corner, far from others. In a video analysis of 216 ice-skating falls in children, 93% of the children tried to break the fall with arms or hands, and in 13% the head hit the ice [2]. So wear a helmet. Warm up hips, knees and back beforehand and increase the number of revolutions slowly.
Plan the transitions with a photo grid: take three phone photos from a video, one per position and one during the change. Compare whether the position is low or high enough at the revolution and the body stays over the skating foot. This way you recognise the transition mistake without having to feel it (practical experience).
A spin that links at least two different basic positions, each with at least two revolutions [1]. The basic positions are camel, sit and upright.
In the free-skate rulebook at least ten from entry to exit; if they are missing, the judges reduce the grade [1]. For your hobby this is a benchmark.
In the rulebook a change of foot is optional in the free-skate combination, and it must be preceded and followed by a position of at least three revolutions [1]. You will learn that later in its own guide.
The rulebook makes no statement on this. Most people combine the position they master most securely with a second one they are working on (practical experience).
