- DEL: Deutsche Eishockey LigaThe Deutsche Eishockey Liga (DEL) has been the top tier of German ice hockey since 1994. After the regular season, pre-playoffs and best-of-seven playoffs decide the German champion.League & competition · 3 min
- Figure skating jumps: Axel, Lutz, flip & co.Figure skating has six basic jumps: toe loop, Salchow, loop, flip, Lutz and Axel. They differ in the take-off – whether with the help of the toe pick (toe jump) or from the edge (edge jump). The landing is almost always backwards on the right foot (for anticlockwise rotators).Term · 4 min
- Ice preparation & ice resurfacer (Zamboni)The ice resurfacer shaves a thin layer off the ice, collects the resulting snow, cleans the surface and lays down a thin film of warm water that freezes into a smooth new layer of ice. Frank Zamboni built the first such machine in California in 1949.Background · 3 min
- IcingIcing occurs when a team shoots the puck from its own half over the opposing goal line and nobody touches it. Play is stopped, and the faceoff follows in the offending team's defensive zone.Term · 3 min
- Making ice & ice temperature by sportArtificial ice is made by applying water in many thin layers to a chilled concrete slab containing cooling pipes. The finished ice is usually only a few centimetres thick. The ice is tempered differently depending on the sport: colder and harder for ice hockey and speed skating, slightly warmer and softer for figure skating.Background · 3 min
- Natural ice vs. artificial iceNatural ice forms through frost without technology, for example on lakes or flooded areas. Artificial ice is produced by refrigeration plants that cool pipes beneath the ice surface. Artificial ice is predictable and even; natural ice depends on the weather but offers special experiences.Background · 4 min

- Offside in ice hockeyIn ice hockey, an attacker is offside if both skates cross the blue line into the attacking zone before the puck has completely crossed that line. Play resumes with a faceoff in the neutral zone.Term · 3 min
- Pebbling: why curling ice is bumpyPebbling is the spraying of fine water droplets onto curling ice. The droplets freeze into tiny bumps, the "pebble". The stone rests only on these tips, so it glides further and runs its typical curve.Term · 3 min
- Power play and penalty killing in ice hockeyA power play means a man advantage: one team has more players on the ice because an opponent is serving a time penalty. The shorthanded team tries to get through the penalty without conceding (penalty killing).Term · 3 min
- Puck: dimensions, material and why it is frozenThe puck is the hard rubber disc used in ice hockey: 2.54 cm thick, 7.62 cm in diameter and weighing 156 to 170 grams. It is frozen before the game, because frozen rubber bounces less and glides more evenly over the ice.Term · 3 min
- Shootout in ice hockeyThe shootout decides an ice hockey game if the score is still tied after regulation and overtime. Shooters take turns skating alone towards the goaltender. The result then shows "SO" (after shootout).Term · 3 min

Zamboni, who built a first working model for his own rink in 1949. Today the brand name stands worldwide for the machine that smooths the ice during breaks.Background · 3 min

- Bandy
A bandy field is about the size of a football pitch. That is why bandy is often played on the same ice surfaces used for speed skating.

The Olympia Bob Run in St. Moritz is rebuilt from natural ice every winter. It is the last natural-ice track on the World Cup circuit.

Broomball sticks got their name for a reason: originally the game was played with real, taped-up brooms.

Most competition curling stones are made from granite from Ailsa Craig, a small uninhabited island off the west coast of Scotland.

Without pebble, a curling stone would practically stick to smooth ice and stop after a few metres. Only the tiny ice bumps make the game possible.

The ice in an ice hockey arena is usually only a few centimetres thick. Underneath are pipes through which a coolant is pumped.

Nutrition in ice sports
Ice sports place special demands on eating and drinking: short, hard efforts, long competition days and cold rinks where thirst kicks in later. Here you will find the basics, a game-day planner and answers to common myths.
Ice & technology: behind the scenes
Background · 3 Min.
History of ice rinks and artificial ice
For centuries, ice sports depended on natural ice and cold winters. In 1876 the first artificial ice rink, the Glaciarium, opened in London. Since then, refrigeration technology, covered rinks and modern arenas have made ice sports possible in every season and almost anywhere.
Topic overview · 2 Min.
Ice & technology
No perfect ice, no ice sports. In this section we explain what happens behind the scenes: how artificial ice is made, why each sport needs a different ice temperature, how the ice resurfacer works and what role ice technicians play.

Ice preparation & ice resurfacer (Zamboni)
The ice resurfacer shaves a thin layer off the ice, collects the resulting snow, cleans the surface and lays down a thin film of warm water that freezes into a smooth new layer of ice. Frank Zamboni built the first such machine in California in 1949.
Background · 4 Min.
Ice resurfacer cutting and conveying system
The cutting and conveying system is where the actual ice work happens: a blade in the conditioner shaves a thin layer off the surface, and augers carry the resulting ice snow into the snow tank.
Background · 5 Min.
Ice resurfacer drive unit
The drive unit is the powerhouse of the ice resurfacer: a combustion engine or an electric drive moves the vehicle and at the same time drives the hydraulics that operate the conditioner, augers and brush.
Background · 4 Min.
Ice resurfacer hydraulic and control system
The hydraulic and control system moves the ice resurfacer's working units precisely and reliably: a pump builds up oil pressure, valves distribute it, and cylinders and hydraulic motors move the conditioner, augers and snow tank, controlled by the driver via levers and a display.
Background · 4 Min.
Ice resurfacer wash and finisher system
The wash and finisher system cleans the freshly shaved ice and builds up the new layer: wash water flushes dirt out of grooves and is sucked back up, then a towel (finisher) spreads a thin film of ice-making water that freezes into a smooth surface.
Background · 4 Min.
Ice resurfacer water tank system
The water tank system stores the water for ice preparation and distributes it in a controlled way: clean ice-making water is spread behind the conditioner and, depending on the model, a separate circuit picks up the dirty wash water again.
Background · 3 Min.
Ice speedway
Ice speedway is a motorcycle racing sport on ice ovals. The bikes run with long metal spikes in their tyres, allowing extreme lean angles in the corners. Usually four riders race against each other over a few laps.
Background · 3 Min.
Ice technician: the job behind perfect ice
Ice technicians are responsible for making, maintaining and ensuring the quality of the ice surface in rinks. They drive the ice resurfacer, monitor the refrigeration plant and rink climate, build the ice at the start of the season and adapt it to each sport.

T-Blade: the interchangeable blade system for skates
T-Blade is a blade system for ice hockey and recreational skates in which the running surface is not sharpened but swapped as an interchangeable runner. Holder, stabiliser, runner and clips can be combined in different colours; the system is mounted on boots from established manufacturers.
