Skiing performance could be defined as our personal mode to make well use of inner (skills, behavior, effort, etc.) and outer conditions (environment, motion, external forces, etc.) to execute our skiing and obtain a result.
Performance depends on our ability to perceive action possibilities (affordances) that the environment allows, i.e., perceiving which actions are possible and which are not. The ideal performance requires to be conscious of the limits of our actions capabilities, which we should not exceed. For a successful performance, our present state must be observed, perceiving if we are or not, as an example, turning enough to reach the desired trajectory. The criteria that could be taken to define our ideal performance are, first, if we achieved our goal, and then, if the effort and the time consumed to achieve it was the necessary minimum.
Expert skiers not only stand on the information about their current performance; they also rely on information about the ideal performance, i.e., their maximum action capacity. Effective performance is expressed when accomplishing small adjustments to minimize the differences between real and ideal performance.
When skiing we usually encounter two types of situations: in predicted situations we apply dominion, anticipation, automation, precision, and economy of effort; in unpredicted situations we employ adaptation, modification, and motor actions transferring. To get closer to the ideal performance, we must optimize our behavior by using all of our resources to minimize the effects of unpredicted situations.
Observing and Understanding Other Skiers’ Actions Improves Our Own Performance
The movements and actions carried out by other skiers are, perhaps, the most important stimulus to improve skiing performance itself. The understanding of movement or action execution is based, in addition to our cognitive aspect, on the visual analysis of the observed execution, both globally and analytically, and the technical elements that make up the action.
To optimize performance, according to some authors, visual information alone would not provide a complete understanding of the observed action, and propose that it can be achieved only by activating our motor representation as observers. In other words, the observation of an action would be fully understood once the observed action has access to our neural networks and thus would allow it to be related to other similar actions that we already perform.
Our motor area would be involved together with our visual system not only in the recognition of the action but also in the understanding of the composition of movements, of how they are executed and related to other actions. In addition, this understanding would allow predicting the actions of others. When a skier performs the first motor act of an action, for example, the pole’s preparation as a preparatory part of a change of direction, we, as observers, can perceive what the purpose and the directionality of that particular action is.
Perceptual Interference Affects Performance
One of the problems for optimal performance in our skiing is interference, i.e., the variability of sensory information we perceived which produces uncertainty, needing concentration and focus to compensate it.
We are concentrated in most of our skiing, if so we choose, but only focus a reduced period of time to a specific stimulus (object or situation); otherwise, our mental fatigue will be rapidly reached. Being concentrated allow us attaining predictions and conclusions about the environment; this is, noticing the environment layout. It also consents interpreting sensory information associating it with our memories of past experiences.
During these perceptions, our brain is constantly estimating if snow, slope, and terrain settings have the same properties or if our skis will behave in the same way compared to previous involvements in the same situations. When these interpretations fail, then our motor behavior declines and our performance is impaired. The result is materialized in a tensed muscular functioning, increasing our effort, and not receiving instructions since we feel confused, so we must react to the lack of the situation foresight.
Conclusion
Our brain is constantly simulating future actions and subconsciously predicting how movements and actions will influence the environment to be able to plan, and therefore reduce, the negative effect of interference while improving our performance.
