As of 1994, there were estimated to be 55 million people worldwide who engaged in alpine skiing. The estimated number of skiers, who practised alpine,
cross-country skiing, and related snow sports, amounted to 30 million in Europe, 20 million in North America, and 14 million in Japan. As of 1996, there were reportedly 4,500 ski areas, operating 26,000 ski lifts and enjoying skier visits. The predominant region for downhill skiing was Europe, followed by Japan and the US.

word , which means "split piece of wood or firewood."
[Caprona, Yann de: Norsk etymologisk ordbok. Oslo: Kagge forlag, 2014. .] Skis were first invented to cross wetlands and marshes in the winter when they froze over. Skiing was an integral part of transportation in colder countries for thousands of years. In the 1760s, skiing was recorded as being used in military training. The Norwegian army held skill competitions involving skiing down slopes, around trees and obstacles while shooting.
The birth of modern alpine skiing is often dated to the 1850s, and during the late 19th century, skiing was adapted from a method of transportation to a competitive and recreational sport.
[ Norwegian legend ]Sondre Norheim

Technique
A skier following the fall line
A fall line (or fall zone) is the area where an upland region and a coastal plain meet and is typically prominent where rivers cross it, with resulting rapids or waterfalls. The uplands are relatively hard crystalline basement rock, and the coa ...
will reach the maximum possible speed for that slope. A skier with skis pointed perpendicular to the fall line, across the hill instead of down it, will accelerate more slowly. The speed of descent down any given hill can be controlled by changing the angle of motion in relation to the fall line, skiing across the hill rather than down it.
Downhill skiing technique focuses on the use of turns to smoothly turn the skis from one direction to another. Additionally, the skier can use the same techniques to turn the ski away from the direction of movement, generating skidding forces between the skis and snow which further slow the descent. Good technique results in a fluid flowing motion from one descent angle to another one, adjusting the angle as needed to match changes in the steepness of the run. This looks more like a single series of S's than turns followed by straight sections.
Stemming
The oldest and still common type of turn on skis is the stem, angling the tail of the ski off to the side, while the tips remain close together. In doing so, the snow resists passage of the stemmed ski, creating a force that retards downhill speed and sustains a turn in the opposite direction. When both skis are stemmed, there is no net turning force, only retardation of downhill speed.
Carving
Carving is based on the shape of the ski itself; when the ski is rotated onto its edge, the pattern cut into its side causes it to bend into an arc. The contact between the arc of the ski edges and the snow naturally causes the ski to tend to move along that arc, changing the skiers direction of motion.
Checking
This is an advanced form of speed control by increasing the pressure on one inside edge (for example the right ski), then releasing the pressure and shifting immediately to increasing the other inside edge (the left ski). Then repeat if necessary. Each increased pressure slows the speed. Alternating right and left allows the skis to remain parallel and point ahead without turning. The increase and release sequence results in the up and down motions of the upper body. Some skiers go down the top of moguls and control the speed by checking at the tops. This is how they can practically go straight down the fall line without gaining speed.
Snowplough turn
The snowplough turn is the simplest form of turning and is usually learned by beginners. To perform the snowplough turn one must be in the snowplough position while going down the ski slope. While doing this they apply more pressure to the inside of the opposite foot of which the direction they would like to turn. This type of turn allows the skier to keep a controlled speed and introduces the idea of turning across the fall line.
Equipment
Skis
Modern alpine skis are shaped to enable carve turning, and have evolved significantly since the 1980s, with variants including powder skis, freestyle skis, all-mountain skis, and children's skis. Powder skis are usually used when there is a large amount of fresh snow; the shape of a powder ski is wide, allowing the ski to float on top of the snow, compared to a normal downhill ski which would most likely sink into the snow. Freestyle skis are used by skiers who ski terrain parks. These skis are meant to help a skier who skis jumps, rails, and other features placed throughout the terrain park. Freestyle skis are usually fully symmetric, meaning they are the same dimensions from the tip of the ski to the backside (tail) of the ski. All-mountain skis are the most common type of ski, and tend to be used as a typical alpine ski. All-mountain skis are built to do a little bit of everything; they can be used in fresh snow (powder

) or used when skiing groomed runs. Slalom race skis, usually referred to as race skis, are short, narrow skis, which tend to be stiffer because they are meant for those who want to go fast as well as make quick sharp turns.
Bindings
The binding is a device used to connect the skier's boot to the ski. The purpose of the binding is to allow the skier to stay connected to the ski, but if the skier falls the binding can safely release them from the ski to prevent injury. There are two types of bindings: the heel and toe system (step-in) and the plate system binding.[
]
Boots
Ski boots are one of the most important accessories to skiing. They connect the skier to the skis, allowing them full control over the ski. When ski boots first came about they were made of leather and laces were used. The leather ski boots started off as low-cut, but gradually became taller, allowing for more ankle support, as injuries became more common . Eventually the tied laces were replaced with buckles and the leather boots were replaced with plastic. This allowed the bindings to be more closely matched to the fit of the boot, and offer improved performance. The new plastic model contained two parts of the boots: an inner boot and an outer shell. The inner part of the boot (also called the liner) is the cushioning part of the boot and contains a footbed along with a cushion to keep a skier's foot warm and comfortable. The outer shell is the part of the boot that is made of plastic and contains the buckles. Most ski boots contain a strap at shin level to allow for extra strength when tightening the boots.[
]
Poles
Ski poles, one in each hand, are used for balance and propulsion.
Helmet
Ski helmets reduce the chances of head injury while skiing. Ski helmets also help to provide warmth to the head since they incorporate an inner liner that traps warmth. Helmets are available in many styles, and typically consist of a hard plastic/resin shell with inner padding. Modern ski helmets may include many additional features such as vents, earmuffs, headphones, goggle mounts, and camera mounts.
Protective gear
The protective gear used in alpine skiing includes: mouth guards, shin guards, chin guards, arm guards, back protectors, pole guards, and padding. Mouth guards can reduce the effects of a concussion and protect the teeth of the athlete. Shin guards, pole guards, arm guards and chin guards are mainly used in slalom skiing in order to protect the body parts having impact with the gates. Back protectors and padding, also known as stealth, is worn for giant slalom and other speed events in order to better protect the body if an athlete were to have an accident at high speeds.

Ski trail ratings
In most ski resorts, the runs are graded according to comparative difficulty so that skiers can select appropriate routes. The grading schemes around the world are related, although with significant regional variations. A beginner-rated trail at a large mountain may be more of an intermediate-rated trail on a smaller mountain.
In the United States and Canada, there are four rating symbols: Easy (green circle), Intermediate (blue square), and Difficult (black diamond), and Experts Only (double black diamond) Ski trail difficulty is measured by percent slope, not degree angle. A 100% slope is a 45-degree angle. In general, beginner slopes (green circle) are between 6% and 25%. Intermediate slopes (blue square) are between 25% and 40%. Difficult slopes (black diamond) are 40% and up. Although slope gradient is the primary consideration in assigning a trail difficulty rating, other factors come into play. A trail will be rated by its most difficult part, even if the rest of the trail is easy. Ski resort

Safety
In 2014, there were more than 114,000 alpine skiing-related injuries treated in hospitals, doctor's offices, and emergency rooms.
The most common types of ski injuries are those of the knee, head, neck and shoulder area, hands and back. Ski helmets are highly recommended by professionals as well as doctors. Head injuries caused in skiing can lead to death or permanent brain damage. In alpine skiing, for every 1000 people skiing in a day, on average between two and four will require medical attention. Most accidents are the result of user error leading to an isolated fall.[ Learning how to fall correctly and safely can reduce the risk of injury.][
