Understanding and preparing the Axel: forward take-off, one and a half rotations, backward landing. Prerequisites, biomechanics, risks. Only with a coach.
The honest answer first: the Axel is the only jump with a forward take-off. It takes off from the forward outside edge, lands backward and has one and a half rotations in the single Axel, whereas all other single jumps have one rotation [1]. Exactly this extra half turn makes it so hard.
This guide is deliberately not an imitation manual. The Axel is a safety-critical jump: it belongs in the hands of a coach, with a structured build-up and often a safety system. Here you get the understanding, the prerequisites and the honesty you need to decide whether and when to tackle it.
These steps describe the build-up a coach works out with you. They are not a self-learning plan.
Ask yourself: do you land the waltz jump, Salchow and toe loop securely, with a soft knee and a stable roll-out? If not, the Axel is too early. Milestone: you land each of the three jumps in four of five attempts.
The Axel demands more take-off speed. In a study of eleven youth skaters the vertical take-off speed rose from the waltz jump (1.77 m/s) to the single Axel (2.24 m/s) [3]. The leg muscles quadriceps, hamstrings and shin muscle were more active before take-off [3]. In a review, box jumps and medicine ball throws count as important parts of dry-land training for jumpers [4]. Milestone: your coach is satisfied with strength and landing.
The analysis of 16 skaters divides the Axel take-off into three phases: glide, transition, pivot [2]. In the glide the speed stays constant and over half of the angular momentum for flight is already built up here [2]. In the transition the skater gains vertical velocity by rotating the blade about its long axis [2]. In the pivot he rocks onto the toe picks [2]. For you that means: the rotation comes from the take-off, not from wrenching around in the air. The knowledge is important, the execution belongs in a coach's hands.
The first Axel attempts are made by your coach with you, often on a pole harness (practical experience). That takes the fear of impact away and lets you feel the take-off. Milestone: you jump the half-rotated take-off in a controlled way, with safety.
Only when the backward landing on the outside edge is clean do you go further. With too little rotation the jump counts under ISU rules as "under-rotated" (more than a quarter but less than half a revolution missing) or "downgraded" (half a revolution or more missing) [5]. A backward-starting take-off is judged as downgraded in the Axel [5].
Honestly: the right time does not come from wishing but from the checklist. If waltz jump, Salchow and toe loop are secure, leg strength is built and your coach agrees, then it is time (experience, not a study). If one of them is unclear, it is not. The Axel forgives less than the other jumps, because you take off forward and land backward. That is no reason for fear, but a reason for patience. Whoever invests months in landing, strength and edge work saves weeks full of frustration and falls later.
This guide explains and motivates, it does not replace supervised training. The Axel is safety-critical: it has the most rotation of the single jumps and a backward landing after a forward take-off. Never try it alone or without guidance. Repeated high jump load can cause overuse injuries of the legs in youth skaters [3]; for adults there is hardly any data. Wear a helmet and pads and, when in doubt, let yourself fall sideways (see the guide "Falling and Getting Up on the Ice"). With pain in knee, hip or back: pause and have it checked.
Ask your coach for video from the side. Whoever sees the take-off in slow motion recognises pre-rotation, dropping and landing posture. According to research the landing is one of the most critical parts of a jump [6]; a video shows you whether your knee absorbs it.
Because it is the only jump with a forward take-off and in the single Axel has one and a half instead of one rotation [1]. That adds a half turn in the air, and you land backward. The take-off also needs more vertical velocity than the waltz jump [3].
That cannot be put in numbers reliably. It depends on jumping experience, strength and coaching, and we know of no solid study. Plan in months to years (experience) and stick to the milestones.
Possibly, but individually. The skaters studied are youth and competitive skaters [2][3]; for recreational adults there is no data. Have a coach check your prerequisites and joints before you try.
Both take off forward. The waltz jump has half a rotation, the single Axel one and a half [1][3]. The Axel therefore needs more take-off speed and more rotation; a half turn is added in the air.
