I. Characteristics of Alpine Skiing
1. Standard alpine skiing refers to the sport in which individuals stand on a pair of skis, one under each foot, and hold a pair of ski poles, descending downhill from the mountain. As a specialized sport that originated primarily in the European Alps, it is referred to internationally as "Alpine skiing."
Alpine skiing is a snow sport conducted on mountain slopes in nature, characterized by its strong connection to the natural environment. It symbolizes and represents the essence of skiing and is the main discipline in recreational skiing.
2. Characteristics of Alpine Skiing:
(1) The primary force in alpine skiing is gravity. The main force propelling a person downhill comes from Earth's gravitational pull, requiring minimal internal physical effort—this is a defining feature of alpine skiing.
(2) The conditions in alpine skiing are complex and ever-changing: the terrain varies, snow conditions differ, and the environment is highly influenced by natural factors. Skiers must constantly adapt to these changing conditions, which is another key characteristic of the sport.
(3) The integration of ski equipment with the human body is another hallmark of alpine skiing. This sport utilizes specialized gear such as skis, ski boots, bindings, and poles. These tools transmit forces from the snow to the body and vice versa—from the body’s kinetic energy to the snow surface. Without this equipment, maintaining balance would be impossible. Thus, the skis can be considered an extension of the body, while ski boots and bindings serve as intermediaries between the person and the skis. Additionally, the structural design and shape-shifting capabilities of the skis further enhance this integrated feeling.
II. Alpine Skiing Events Suitable for the General Public
Although events like slalom and giant slalom are technically demanding and require advanced turning skills, they involve shorter distances, smaller vertical drops, and relatively slower speeds compared to downhill and super-G events, making them safer and well-suited for public participation. Competitive downhill and super-G events are not recommended for general recreational skiing.
III. Classification of Basic Techniques in Alpine Skiing
The basic techniques of alpine skiing include downhill skiing and turning, along with deceleration/stopping techniques and uphill techniques with skis on.
Downhill techniques include parallel straight skiing, snowplow straight skiing, as well as diagonal and traverse skiing.
Turning techniques include snowplow turns, half-snowplow turns, parallel turns, jump turns, step turns, and carved turns.
Deceleration and stopping techniques include snowplow braking, hockey-stop, and parallel turn stops.
Uphill techniques with skis on include traverse climbing, wedge climbing, and zigzag climbing.
IV. Functions and Appeal of Modern Recreational Skiing
Skiing (including snow viewing, snow walking, and snow play) benefits physical health, cultivates sentiment, enhances cold resistance, strengthens willpower, helps prevent diseases, and maintains a fit and attractive physique (including weight loss). People of all ages and genders can enjoy the fun and charm of skiing, making it highly appealing and widely participated in—especially alpine skiing.
With its fast pace, spectacular views, thrilling elements, and dynamic conditions, alpine skiing is regarded as the essence and symbol of the sport. It serves as a primary activity for both fitness and ski tourism. The wide variety of skiing techniques allows for flexible use in diverse environments, promoting balanced physical development and effectively training the central nervous system, cardiopulmonary function, reaction and judgment abilities, as well as balance and agility.
The cold environment of skiing also fosters bravery, resilience, and a strong will to endure harsh conditions. Prolonged movement through snowy landscapes quickly converts stored fat and sugar into heat energy, aiding in mental alertness, lung health, and the prevention of cardiovascular, respiratory, obesity, depression, and fatigue-related illnesses.
Skiing takes you away from urban noise and pollution, immersing you in snow-covered mountains, forests, and fields, where you become closely connected with nature. Amidst the glistening white landscape, fresh flowing air, bright sunshine, and expansive views, you can witness the ever-changing wonders of winter. As a skier, immersed in this “winter wonderland,” you become one with the mountains, forests, and snow, dancing with the snowflakes and enjoying the boundless joy bestowed by nature. You’ll feel refreshed and invigorated, with worries and fatigue washed away, experiencing purification of the body and elevation of the spirit in nature.
V. Interrelationships Among Various Alpine Skiing Techniques
1. Skiing encompasses a rich array of content and diverse techniques, including flat-ground techniques, downhill techniques, turning techniques, uphill techniques, and jumping techniques. Each category contains numerous specific skills. For example, alpine skiing involves descending from mountain peaks, featuring thrilling downhill runs, captivating turns, and impressive aerial maneuvers—sometimes dazzling, sometimes astounding.
2. Among the dozens of technical movements in alpine skiing, there are intrinsic connections. Therefore, when learning alpine skiing techniques, it’s essential to start with the basics under a systematic approach, focusing on improving key technical aspects, thereby steadily enhancing overall skiing ability. Basic techniques include the fundamental skiing stance, straight skiing, snowplow skiing, diagonal skiing, and traverse skiing.
Key techniques include snowplow turns, parallel turns, and new carving methods with shaped skis.
The deeper your understanding of the interconnections among various alpine skiing techniques, the greater the benefits you will gain.
VI. Ski Shape, Position, and Tracks of Two Skis
1. Different skiing styles require the two skis to adopt distinct shapes and positions. Due to the differences in ski shape and position, they also leave different tracks on the snow.
2. In parallel straight downhill skiing, both skis slide down parallel to the fall line, creating two symmetrical left and right linear tracks. In semi-wedge straight downhill skiing, the difference in ski shape and position leads to asymmetrical left and right tracks. In parallel diagonal downhill skiing, the tracks form an angle with the fall line and are asymmetrical.
3. During turns, the tracks left by the two skis resemble crescent-shaped arcs (styles like stem turns or step turns do not produce arced tracks). The smaller the angle between the direction of the skis during a turn and the fall line, the less resistance there is, resulting in higher speed and more slender tracks. Conversely, the greater the lateral elements of the ski shape and position during a turn, the larger the area of the track becomes, and the greater the distance between the inner edge (inner arc) and outer edge (outer arc), meaning the track widens laterally.
4. Super wide turns or wide turns differ significantly in ski shape and position from short turns, resulting in distinctly different tracks.
5. A skier’s ability to control the skis primarily involves timely adjustments to the shape and position of the two skis to achieve goals such as descending, turning, accelerating, or decelerating. The advent of shaped skis has reduced the difficulty of controlling the shape and position of the two skis.
Seven. Common Terminology in Alpine Skiing Techniques
In the study, practice, and discussion of alpine skiing techniques, many terms are involved. The main terms are summarized below and should be carefully understood in the context of actual skiing experience.
Gravity: A skier’s body weight can be roughly understood as gravity. The shift in the proportion of weight supported by the two skis (referred to as weight transfer) can also be understood as a shift in body weight.
Center of Gravity: Refers to the point where the total weight of the human body acts. Its direction points toward the center of the Earth. When standing upright at rest, the center of gravity is generally located 7 cm in front of the third sacral vertebra, below the navel, with women's centers of gravity slightly lower than men's. If the human body is viewed as an upright object symmetrical in all directions (left, right, front, back), the center of gravity would definitely lie on the central line of the symmetrical cross-sections in both directions.
The center of gravity may sometimes be inside the body and other times outside during skiing.
The direction of the center of gravity’s movement in skiing is multidimensional, involving a combination of forward, backward, left, right, upward, and downward shifts.
Weight Transfer: Generally refers to the shift of load between the left and right sides during skiing.
Center of Gravity Projection Point: Generally refers to the point on the snow where the line connecting the center of gravity and the Earth’s center intersects.
Load Bearing or Weight Bearing: Generally refers to the ski (or the loaded leg/foot) that carries the majority of the body’s weight.
Applying Force (Pressure): Generally refers to the pressure exerted on the skis (legs, feet) by the combined force of gravity or gravity and muscular internal forces.
Support Area: Generally refers to the imagined stable area formed by the position of the skis on the snow, their shape, and position (sometimes also considering the support of ski poles).
Fall Line: The straight path a ball would take when rolling downhill from the mountaintop without changing direction. The fall line is perpendicular to the contour lines (elevation lines) on a map.
Downhill Skiing: Refers to sliding mostly straight down a slope along the fall line.
Turning: Refers to the act of sliding down the slope while alternately switching the direction of the skis from side to side. In competitive skiing, this is called a turn or "slalom."
Climbing or Ascent: Refers to moving uphill while wearing skis.
Ski Shape: Refers to the form taken by the two skis on the snow or in space. The main ski shapes in alpine skiing include parallel, wedge, and V-shaped.
Parallel Ski Shape (Parallel Form): Both skis are parallel, sometimes lying flat on the snow surface; other times, one edge of each ski is parallel and cutting into the snow.
Wedge Ski Shape: The two skis are in a front-narrow, back-wide formation, usually with both inside edges tilted upward. The wedge shape also includes the semi-wedge form.
V-Shaped Ski Shape: The two skis are in a front-wide, back-narrow formation, with one ski necessarily lifted off the snow and in the air. Both skis cannot be on the snow simultaneously.
Ski Position: Refers to the location of the two skis on the snow or in space.
Ski Tracks: Refers to the marks left on the snow by the skis as they move.
Ski Pole Marks: Refers to the circular impressions left on the snow after the ski poles are planted.
Turn Arc Track: Refers to the track left on the snow by the skis during a turn, typically in a crescent or arc shape. This is one type of ski track.
Turn Arc Line: Refers to the central curve of the turn arc track. The outward side is called the outer edge, and the inward side is called the inner edge.
Turn Radius: Refers to the line connecting a point on the turn arc line to the hypothetical center of the inner circle. The turn radius in slalom skiing is generally between 11–16 meters.
Turn radius (turn arc): Determined by the turning radius. The larger the turning radius, the wider the turn arc; the smaller the turning radius, the tighter the turn arc.
Turning elements: The main factors involved in turning, primarily including gravity (body weight), edge control, and ski shape.
Outside ski (leg, foot): Refers to the ski (leg, foot) on the outside of the turn arc.
Inside ski (leg, foot): Refers to the ski (leg, foot) on the inside of the turn arc.
Downhill ski (leg): The ski (leg) positioned on the lower side of the slope. Usually the outside ski (leg).
Uphill ski (leg): The ski (leg) positioned on the upper side of the slope. Usually the inside ski (leg).
Active ski: The ski that plays the leading role during a turn, i.e., the one bearing more weight, usually the outside ski or downhill ski.
Passive ski: The ski that does not play the leading role during a turn, i.e., the one bearing less weight or no weight, usually the inside ski or uphill ski.
Ski edge: Refers to the metal sides on both edges of the ski base.
Inner and outer ski edges: In the basic skiing stance, the inner edges of both the left and right skis. There are also two outer edges.
Edging: Refers to the angle formed between the base of the ski and the snow surface while skiing. Edging is mainly reflected in the inner edge of the active ski.
Edge transition: Refers to the shift between the inner and outer edges of one ski, and the load transfer between the two inner edges of the skis during a turn.
Carving into the snow: Often refers to the ski edges firmly biting into the snow surface while skiing. Mainly reflected in the inner edge of the active ski.
Holding an edge: Generally refers to keeping the ski edge steadily upright against the snow surface when stationary.
Edge angle (steep edge angle): The angle formed between the ski and the snow surface when edging.
Ski angle of attack: The angle formed between the ski and the original direction of travel. The angle of attack is directly proportional to resistance.
Skid (side skid): Refers to the phenomenon where the downhill ski slides outward and backward under load and edge pressure during a turn in alpine skiing.
Snow surface: Specifically refers to the snow layer surface suitable for skiing.
Snow resistance (snow drag): Refers to the resistive force exerted by snow on the skis during skiing.
Leaning in: During a turn, due to factors such as edging, body posture, and centrifugal force, certain parts of the body must lean inward past the skis to maintain balance. This state is called leaning in.
Counter position: During a ski turn, the knees and hips tilt inward for edge control and balance, while the upper body tilts and twists in the opposite direction, forming a body posture known as the counter position. In typical small turns, the counter is mainly seen in the knees and hips. In fast, large turns, the counter may appear in the hips or connect from the hips through the knees.
Extension: At the moment of transitioning between two adjacent turns, stepping down (or single-foot stepping) on the skis—mainly by straightening the knees (not the upper body)—lifts the body’s center of gravity upward and forward, momentarily “unweighting” the skis. This facilitates changing ski direction and exchanging forces, and this motion is called extension.
Forward lean: In the basic skiing stance, actions such as “pushing the knees forward,” “slightly leaning the upper body forward,” and applying pressure with the ball of the foot are called forward lean. The forward lean ensures the center of gravity does not fall behind.
Sitting back: Refers to lowering the hips while skiing, causing the center of gravity to fall behind. “Sitting back” is the opposite of forward lean and is an incorrect movement.
Snow temperature: The temperature measured beneath the snow surface, distinct from air temperature. Air temperature is greatly affected by weather conditions, while snow temperature is relatively stable. Measuring snow temperature is a key basis for assessing changes in snow quality and waxing skis.
Ski flex (tension, stress): Refers to the deformation of the ski where the front and rear ends rise upward and the middle bends downward under load (force). This deformation creates a rebound force.
Ski shadow: The approximate projection of the ski’s shape on the snow surface.
Gate: Refers to the markers set up on the ski slope that define the specific skiing route. Competition slalom gates consist of two poles, while giant slalom, super-G, and downhill gates consist of four poles (two on each side), with a large flag between each pair of poles. Both the poles and flags are alternately colored red and blue.
