Three markers instead of gut feeling: how to film starts and top speed, what becomes visible in the frontal plane and how a finding becomes a training task.
Without video you are arguing feeling against feeling — and feeling loses. The good news: you do not have to see everything, only three things, and all three are measurable with a phone from the boards. Exactly the three markers by which research separates high-calibre from lower-calibre skaters.
The gap in question is quantified: high-calibre players complete a full 30-metre sprint around 12 percent faster and show longer stride lengths and greater segmental ranges of motion [4]. Mechanically behind that sit greater amplitudes and higher rates of joint movement in the sagittal AND the frontal plane — plus a greater lateral excursion in the push [2]. Translated: the fast people do not skate harder, they skate wider apart.
And the engine has a name. Fast skating is characterised by a higher hip abduction velocity in the push phase, with the work shifting from hip extension to abduction as speed rises [1]. That is the decisive message for your camera: the most important marker sits in the frontal plane — filmed from the front or behind, not from the side. Film only from the side and you see half the sport.
Place the first camera facing the skating line head-on or directly behind it, at hip height. This angle shows abduction, lateral excursion and left-right symmetry — exactly the plane where the decisive differences sit [1][2]. The second camera goes to the side for knee flexion and stride length. If you only have one camera, take the frontal one.
These are two different movements, not two speeds of the same one. In acceleration, a greater hip abduction angle in the first strides goes with a higher acceleration rate; cycle and propulsion duration rise progressively from the second to the seventh cycle, and the knee is more flexed at the start of propulsion [3]. In the start, abduction, external rotation and extension work simultaneously, with higher stride frequency and shorter double-support times in the good ones [6].
The simplest and most frequently violated marker. The foundation of skating is deep knee and hip flexion, because only that produces a long push through to full extension [5]. Check the lowest point of a stride in the side video and compare it across a series. Almost every adult is clearly higher on stride six than on stride one — that is where speed leaks away.
Now the frontal angle. You judge how far the pushing blade travels laterally out of the body line and how fast the hip opens while doing it. This is exactly where classes separate: greater lateral excursion in the push [2] and a higher hip abduction velocity [1]. A skater who stays narrow looks clean and still goes nowhere.
Count the frames in slow motion in which both blades are in contact at once. In high-calibre skaters, double-support times are shorter and stride frequency higher [6]. Every extra moment on two blades is a moment without propulsion — this marker is the most honest, because you can count it instead of estimating it.
A video without consequence is entertainment. Take exactly one marker per four-week block. If depth is missing, work on flexion and strength; if width is missing, on edge work and abduction velocity; if double-support times are long, on frequency and short starting strides. And measure the same distance again at the end — high-calibre players are around 12 percent faster over 30 metres [4], which is the yardstick your work is measured against.
Never film in the middle of a busy sheet and never place tripods in skating lanes. Cameras and phones belong behind the boards or in a closed-off corner; tripping over a tripod is exactly the kind of injury nobody plans for.
Maximal starts are high-intensity stimuli. They belong rested, after a full warm-up and not at the end of a hard session — and certainly not in the days right after a game. Pay particular attention to your groin: the lateral push loads exactly the muscles that tear most often in hockey.
This guide explains an analysis method and replaces neither coaching nor medical judgement. If anything hurts during the test runs, you stop rather than push through.
Always film the same two clips in the same condition: one standing start over your marked distance and one run at top speed, both within the first ten minutes of a session while you are fresh. Four weeks later you repeat exactly the same setup — same camera position, same distance, same point in the session.
The reason is banal and still almost always ignored: without constant conditions you measure your daily form, not your technique. Anyone with the ambition to close the gap between a high-calibre and an average skater — around 12 percent over 30 metres [4] — needs data that can be laid side by side.
Two cameras at hip height: one head-on or directly behind the skating line, one to the side. Fixed markers for a constant distance, slow motion on, no zoom. If only one camera is available, take the frontal one — the key marker, hip abduction in the push phase, is only visible in that plane [1].
Depth, width and time on ice. Depth means knee and hip flexion as the foundation of the long push [5]. Width means lateral excursion in the push, where high-calibre skaters measurably work bigger [2] and move into abduction faster [1]. Time on ice means double-support duration and stride frequency, shorter and higher respectively in good skaters [6].
Because they are two patterns. In acceleration, a greater hip abduction angle in the first strides goes with a higher acceleration rate, cycle and propulsion duration grow from the second to the seventh cycle, and the knee is more flexed at the start of propulsion [3]. In steady state the work then shifts further towards hip abduction [1]. Judge both in one clip and you mix two movements.
Every four weeks, always in the same setup and the same freshness. More often gains nothing, because technical change takes time; less often and you lose the link between training block and result. Also time yourself over your fixed distance — the class difference sits at around 12 percent over 30 metres [4].
Work on exactly one marker per four-week block. If depth is missing, on flexion and strength [5]; if width is missing, on edge work and abduction velocity [1][2]; if double-support times are long, on starting frequency and short first strides [6]. Then repeat the same recording. A finding without a training assignment changes nothing.
