Skiing Sensations

Skiing is constituted in sensations that we experience while sliding over the snow, being these ones our main motivation.

Through the senses, we receive environmental information and these sensations generate perceptions, establishing skiing basic process. Each one of the senses sends information to different brain areas that process it. While we recognize five basic senses, we can consider that the vestibular system contributes to the sense of balance, the proprioceptive collaborates with the sense of our body’s global location as well as its parts individually, and the kinesthesia facilitates movement sensations.

Sensations are signals that cause nerve cell reactions. These signals are picked up by sensory receptors that send information to nerve centers in our brain where it is finally transformed into sensations. The nervous system sends these messages to our brain, interpreting them as changes’ warnings. To trigger a sensation, it is a stimulus that can be external (visual, tactile, thermal, etc.) or internal (fatigue, hunger, dizziness, etc.). The information caused by the stimulus is received by the nervous system and used to stabilize our body.

Sensation intensity depends on the force of the stimulus. The minimum threshold is the minimum intensity for us to detect the stimulus that causes the sensation through sensitivity. This is a feature that depends on our capacity development to react to low levels in which a stimulus is presented. The sensitivity arousal causes a revolution in our consciousness because it generates new thoughts, and then sensations become a reference for our skiing actions. The differential threshold is the amount, in more or in less, of the stimulus so we may experience a sensation variance.

Stimuli detection is influenced by our expectation, experience, motivation and/or fatigue. The content of a sensation depends on stimuli pickup according to our motivation and expectation. Usually, we detect with greater intensity and speed what we are interested in.

For us to evolve, we need to pay attention to what we sense during skiing. Our goal should be to tune up sensation awareness and understand that, from one movement or action, we could get different sensations since a turn is not necessarily perceived as equal to the previous one. Some skiers have their sensorial consciousness numb since they are not capable of perceiving pleasant sensations, but they try to block the unpleasant ones and by doing so, they inhibit the capacity to perceive when something is not right in their skiing. Each skier has a sensation awareness of his own, but also other sensations that could be perceived, leading to a major breakthrough.

While observing, sensing and exploring the environment through movements and actions in motion, we assimilate experiences right from our first glides on snow. Improvements come from perceiving body behavior and this helps to transform us. Practicing postures and movements without sensorial consciousness delays our skiing evolution.

There is a general misapplication of the verb “to feel”, which is used for feelings as well as for sensations. Feelings are subjective experiences; they are complex processes involving emotions, moods, and thoughts; they last a while and refer to the mental, in this case, we “feel” emotions. Sensations are physical stimuli; they are manifested via information pickup through the senses; it is a basic process of the human body by which external information is inferred by the brain and sensory systems; they do not last long and can quickly change; involves physical sensitivity and refer to the corporeal, so we “sense” movements.

Sensation and Movements

Skiing is not just performing movements; it also implies our skill to perceive the differences in sensations which lead to fine adjustments of movements since while executing them, new sensations appear. We should also develop our capacity of making connections between sensations and movements to eliminate unwanted or unnecessary ones. To experience balance adaptations while in motion, we need to explore the relationship between sensing and moving. Towards this, the concept created by Berta and Karel Bobath postulates that we do not learn a movement without the sensation of it.

Sensations and the Environment

We evolve based on constant interactions between our external world (the environment) and our inner world (our body and mind) through sensations and perceptions. As a result of sensations, we record our experiences in our bodies’ consciousness since they act as a connection between our bodies and the environment.

Through perceptions, we can imprint in our brain those sensorial effects which will be recognized and reused. We will understand our skiing when achieving through memory the association of ideas and reflections.

Psychophysics

Psychophysics is the study of the stimulus intensity and the magnitude of a sensation. The Weber-Fechner Law proclaims that exists a proportion between the magnitude of the stimulus (a certain muscle activity specific to skiing) and the change that must occur for us to note a difference in the sensation that the stimulus generates. The greater the intensity of the stimulus that leads to a sensation, the greater must be the change to appreciate the difference in that sensation. On the other hand, the less the intensity of the stimulus, the less will be the variation required, which allows increasing our sensitivity. According to Feldenkrais (1992), the less muscle effort, the greater will be the sensory acuity and the milder the effort, the quicker the learning.

Conditions that influence skiing sensing intensity:

• Paying greater attention to it.
• Guiding our consciousness towards it.
• Having a certain expectation about it.
• Being skillful in specific motor performance or the degree of sensitivity we possess at any given time, since it may vary according to different situations.

Neurocognitive Differentiation: Sensation vs. Feeling

To address the warning about the misapplication of the verb “to feel”, neuroscience maps these two phenomena to entirely distinct brain systems:

• Sensations (The Corporeal / Physical): Processed via the somatosensory cortex, brainstem, and cerebellum. They operate on a millisecond timescale to decode the pure physics of the environment.
• Feelings (The Mental / Subjective): Processed via the limbic system (amygdala), insular cortex, and prefrontal cortex. They are long-lasting cognitive interpretations of emotional states.

Neuroscientific Insight: note that when skiers attempt to mentally block unpleasant “feelings” (like anxiety or fear), they inadvertently numb their somatosensory cortices. This shuts down the physical “sensations” required to detect technical errors.

Conclusion

We should always seek that magic moment in which a sensation appears and transforms our skiing. It could be said how to do it but nobody can tell exactly how to sense a movement or an action. In short, it will be ourselves who will discover that the process of sensorial exploration never ends.

On-Slope Examples of Skiing Sensations

Concept Name	Academic Core	“On-Slope” Example
Sensation (The Corporeal / Physical)	A brief, rapidly changing physical stimulus processed via the somatosensory cortex, brainstem, and cerebellum to decode raw environmental physics on a millisecond timescale.	• Feeling the high-frequency vibration of a hard morning corduroy trail pulsing through the ski bases and into the bones of the feet.
Feelings (The Mental / Subjective)	Long-lasting, complex mental interpretations of emotional states and moods processed via the limbic system, insular cortex, and prefrontal cortex.	• Experiencing a deep, lingering wave of anxiety and apprehension while standing at the windy peak of an unfamiliar black diamond run.
Numb Sensorial Consciousness Block	A cognitive malfunction where a skier attempts to mentally block unpleasant emotions (fear), accidentally shutting down their physical ability to sense when something is wrong technically.	• A terrified intermediate skier stiffens their whole body to brace against fear, completely losing the ability to feel that their inside ski is dangerously catching an edge.
Minimum Threshold	The absolute lowest intensity of a physical stimulus required for a skier’s sensitivity to detect its presence.	• A beginner skier cannot feel a tiny 1-degree change in their ski’s edge angle, while an expert coach instantly detects it the millisecond the steel grazes the snow.
Differential Threshold	The minimum amount of change (more or less) required in a physical stimulus for a skier to experience a conscious variance in sensation.	• A carver executing a long turn needs to feel a distinct 10-pound increase in centrifugal force before their brain realizes they are accelerating.
Sensory-Expectation Tuning	The psychological modulation where a skier’s intent, experience, and fatigue actively dictate the speed and intensity of their stimulus detection.	• A highly motivated racer expects an ice patch around a specific gate, allowing their brain to detect and react to the slippery surface 200 milliseconds faster than normal.
Bobath Sensorimotor Principle	The neuro-technical law stating that the human nervous system cannot truly learn or master a physical movement without experiencing the exact internal sensation of it.	• A skier fails to improve their carving by just reading diagrams; they only master it the moment they feel the unique, frictionless “surge” of a locked-in edge.
The Weber-Fechner Law (Ski Psychophysics)	The mathematical rule proving that the harder you press (high stimulus intensity), the greater the physical change must be for you to note a technical difference.	• A skier who is rigidly forcing and straining their muscles through a turn cannot feel a small bump, whereas a relaxed skier catches every micro-texture.

According to these considerations, you can apply the following suggestions to your own skiing:

• You can interpret your skiing sensations as ‘changes’ warnings’.
• Paying attention to your sensations will generate knew thoughts, becoming a reference in your skiing actions.
• Avoid blocking unpleasant sensations since you may inhibit your capacity to perceive when something is not right in your skiing.
• Every time you practice your movements, make sure you focus on the sensations they produce to tune up awareness and variance, leading to fine adjustments.
• Try to repeat any sensorial effects that you consider helpful to your skiing in order to recognize and reuse them as a form of imprinting them in your brain.
