References are indications we use to orient ourselves or to identify something.
Psychological references
- The “Operating System”: When skiing, the psychological component acts as the “operating system” that processes physical sensations. Psychological references are essential mental anchors managing fear, maintaining focus, and optimizing performance.
- Terrain Interpretation: Slope color-coding serves as primary reference for difficulty, allowing to “read” the mountain and navigate the ski resort based on our perceived exertion and skill level.
- The State of Flow: is the ultimate psychological reference point. This occurs when our executions create asensation of lack of effort as the challenge of the slope matches our skill level exactly. To reach this state, we engage in such a manner in our own skiing experiencing, among other things, the loss of the sense of time.
- Attentional Control: are references we apply when, instead of looking at the “abyss,” we should focus on micro-goals (reaching that tree, finishing this turn). This reduces anxiety by breaking down the threat into smaller pieces.
- Self-Preservation and Social Responsibility: Psychological references include the fear of hurting ourselves or others due to our own mistakes.
- Risk Assessment: Psychological references also comprise the appraisal of objective risks, such as:
- Inadequate speed control.
- Cognitive distractions and diminished situational awareness.
- Poor ability to estimate distances.
- Lack of anticipation of one’s own and others’ trajectories.
- Venturing into challenging terrain without the appropriate technical skills.
Safety references
- Navigational Cues: Signage and trail markers are indispensables references for navigating a ski resort as well as for being aware of potential risks.
- Behavioral Protocols: Knowing the Rules of Conduct (skier’s code) provides the necessary references about how to behave related to right-of-way, overtaking safety, speed control, and appropriate stopping points. The same applies to safety references when venturing out of the marked slopes.
- Physiological Warning Signs: Quadriceps trembling serves as safety reference indicating muscles fatigue.
- Controlled Falling: A safety reference, as a “low-side” fall (dropping toward the uphill side), is a deliberate maneuver to regain control and avoid dangerous forward or backward tumbles.
- The “Last Run” Paradox: A common fatigue reference occurs when saying to ourselves: “One last run and I’m done.” The golden rule in skiing declares that this phrase is dangerous. Our reference point should be to stop while we still feel we have physical reserve.
Sensory References (Kinesthetic & Proprioceptive)
- Mechanical Forces: The four forces acting on us (gravity holding us on the slope, gravity pulling us down the hill, centrifugal effect pulling us outwards, and friction due to wind and snow) plus the centripetal force we generate through muscular effort and skis’ design are essential sensory references.
- Core Displacement: The sensory reference provided by hips’ displacements in four directions (up, down, left, and right) is considered a skiing fundamental aspect.
- Plantar Pressure: The pressure on the soles of our feet, as a reference for balance, is the “tripod” of the foot: ball of the foot, little toe, and heel.
- Edge Engagement: The “feel” of the both edges through the soles of our feet is a reference for sensing whether the skis are cutting through the snow (a rail-like sensation) or skidding (vibrational feedback).
- Acoustic Surface Feedback: The sound of the snow, that is, the noise under the skis, gives us a reference for the type of surface being skied on. A dull, soft sound indicates powder snow; a squeaky scraping sound indicates ice or hard snow.
- Aerodynamic Drag Awareness: The noise of wind resistance serves as a reference to know if our posture is aerodynamically enough or if there is a need to lower our center of gravity.
- Kinesthetic Positioning: The proprioceptive system (“body sense”), as a fundamental reference, is the ability to sense the position of our joints and muscles.
- Triple Flexion Alignment: Feeling that ankles, knees and hips are bent at similar angles is an effective postural reference.
- Dynamic Balance and Plantar Pressure: Weight distribution on feet soles (metatarsal vs. heel) is a reference that tells if we are losing our balance.
- Rotational Mechanics: The feel of the thigh bones (femurs) rotating within the hip sockets is the mechanical reference to steer the tips toward the new turn as the tails slide describing an arc (skidded turn).
- Upper/Lower Body Separation: The feel of a slight twist or “tension” at the waist that is released when starting the new turn is an appropriate sensory reference for hip displacement when changing edges.
- Leg Independence: A reference for leg independence is the feel of different muscle tension between the outer leg (extended) and the inner leg (flexed).
- External Proprioceptive Extensions: By tactile references (the feel of the snow) through skis and poles we receive vibrations that inform us about the condition of the terrain.
- Tactile Timing Trigger: The impact of the pole on the wrist is a tactile reference that marks the rhythm and the moment to start next turn.
- Non-Visual Velocity Awareness: The wind on our face and the sound of air against our helmet are key sensory cues for estimating speed when there are no clear visual references.
- Dynamic Lateral Balance: Feeling the centrifugal effect during turns gives us a reference for how much we can tilt our body into the curve without falling.
- Auditory Feedback: A clean “shhh” or cutting sound indicates a reference for a carved turn, while a harsh scraping sound indicates that we are losing grip (skidding) or that we are braking intentionally.
- Acoustic Awareness: Environmental sounds, like hearing other skiers and snowboarders close by, or the “crump” of shifting snowpacks serves as immediate safety alert.
- Proactive Visual Anchoring: Incorporating the concept of “Eye-lead” (looking ahead), as directing our gaze two or three turns down the hill—anticipating the line—serves as a reference for flow and fear reduction.
Environmental references
- Spatial Disorientation: During flat light conditions, as vertical references are lost, it is advisable to look for high-contrast references provided by trees, trail markers, lift towers, or other skiers.
- Visual Self-Correction: On sunny days, our own shadow cast on the snow is an excellent reference point for checking our posture and movements, almost as a real-time mirror.
- Snow Texture: Changes in snow color and brightness provide clues about its texture and consistency. For example, a bright/mirror-like color is a reference of ice. Matte/opaque snow may show that it is packed snow or powder, and detecting heavy corn or “slushy” textures (spring snow) a reference that allows for the anticipation of friction and glide speed.
- Sequential Trail Referencing: The numbers on the trail markers alongside the slope may give a reference of where we are located and how far is the end of the slope.
- Diurnal Snow Cycle and Exposure: Slope orientation works as a sun reference, where in the north face the snow is usually harder and holds up better throughout the day, but it is colder. In the south face there is more sun, but after midday (mostly in spring) the snow becomes “slushy” (wet and heavy). It is helpful to use this as a reference when choosing where to ski depending on the time of day.
- The Treeline: Vegetation limit, as the presence or absence of trees (treeline) is a macro-reference point for altitude, wind exposure, and visibility.
