Success in high-skill activities relies on more than just muscle memory. It requires the precise synchronization of neural signals and physical execution. This article explores the fundamental roles of rhythm and coordination, examining how internal timing and spatial awareness work together to optimize motor control and athletic performance.
Rhythm
To have rhythm consciousness is to notice the inner harmony allowing us merging and varying different speeds, movements, and actions in time and space. The cerebellum is our brain’s area responsible for movement control, receiving messages from the spinal cord and other areas, coordinating pace and precision.
The execution of each movement produces rhythm, like all in life and in earth (cardiac and respiratory rhythms, lunar and seasonal rhythms, etc.). If movement is coordinated, it expresses a perceptible and rhythmic pace, and in every skiing movement and action we create our own rhythm.
Our task is to recognize the movements or actions we wish to perform, helping in reducing mistakes, improving balance, and economizing efforts, because skiing with sustained rhythm decreases energy expenditure. In addition, rhythm allows synchronization (union in time), i.e., allows relating movements at a particular moment.
Each skier has its own skiing pace which is a spontaneous personal time that applies also to other activities. Skiing with rhythm is skiing with a certain order and the simplest order is the repetition of identical movements and actions. Managing rhythm is learned first by recognizing our own pace and then by modifying and adapting it.
There is rhythm when we organize our executions according to a cycle. Not only we perceive order in our movements and actions performance; we also perceive rhythm in the succession of that orderliness.
The principle of rhythm in skiing corresponds to alternating: we alternate a turn to one side and to the other, alternate poles’ use and edges, the weight transfer from one foot to the other, the bending of one leg and the extension of the other. We ski based on an internal temporal organization over an external space availability. Internal rhythm is our own rhythm in which we perform our actions. In the external rhythm, we adapt, for example, to a slalom course, to turning around trees, or to bumps rhythmic disposal in a mogul field.
We have an established rhythm by personal (physical, emotional), environmental (slope conditions, weather), and circumstantial factors (intensity of the traffic). Likewise, we hold a different motion rhythm which can be slow or fast depending on our technical level and psychophysical conditions.
Rhythm not only refers to the succession of intermixed turns to both sides but also to different turn phases that make up our skiing performance as turn completion-initiation, impulse-inertia, contraction-distension, or action-inaction.
It is observed that through rhythm we establish our interaction with the snow. Having a sense of rhythm is having harmony, an appropriate body balance, and a strong connection between rhythm and our technical gesture. It is also noticed how rhythm develops according to our temporal and spatial orientation capacities, the spatial characteristics, the actions we desire to carry out, and our execution speed.
Coordination
Skiing is deployed through movements which are the particularity of rhythm. In movements’ performance, there areconstant changes in duration, intensity, speed, and space. When linking movements, rhythm plays an elementary role. It is seen the frequent problem to coordinate rhythm in movements’ temporal aspect because we have the tendency to execute them usually too late.
Adjusting movements’ coordination includes adapting the activity of our spinal cord with the cerebellum and the motor cortex. Spinal cord nerve circuits control the movements of our limbs to walk or run, coordinating the counterposition between arms and legs, moving the opposite arm to the advanced leg.
Thanks to the stepping reflex, the unloaded leg moves forward but with the difference that in skiing both arms should be positioned forward and parallel to each other, so this reflex needs to be interrupted, which is not easy to achieve especially in the early stages of the learning process of skiing.
Swinging the outside arm around while turning is very common in skiers who, at beginner levels, do it unconsciously but in advanced levels apply it consciously, believing it is a proper technical reference in recreational skiing. This is not the case in slalom technique, where the racer actively crosses his outer arm in front of his upper body to protect himself from being hit by the slalom pole.
Another habit that comes from the stepping reflex is supporting vertically on the uphill foot to release and advance the downhill one, as in the Direction Change by Extension. The problem this action entails at changing weight before the edge change is that, normally, the extension on the uphill foot is done vertically on the little toe edge, when it would be efficient to oscillate in an oblique way from the uphill foot’s inside arch (the big toe edge) so the CoM is quickly projected towards the new turn’s direction.
We could say that coordinating is arranging and organizing movements in relation to the image of our actions to be executed, setting them at an appropriate pace. It is to relate our body segments within the action spatiotemporal framework, regulating movements’ degrees of freedom while orienting them towards the pretended action.
The first thing seen in a good skier is efficient coordination where all body parts move synchronously. The appropriate movements’ coordination derives in harmonious actions leading to efficient skiing. What is first seen in a beginner, on the other hand, it is the lack of coordination in movements and actions execution.
Anticipation, which is the generation of actions or settings in advance, plays an important role in motor coordination converging spatial and temporal consciousness, i.e., rhythm.
Coordination skills may be global and specific:
- Global coordination skills are divided into those that regulate our movements’ execution and/or adapting movements to unfamiliar situations.
- Specific coordination skills are composed of our body orientation coordination capacity (postural coordination) and balance and rhythm coordination. It is included the oculo-segmental coordination which refers to the coordinated relationship between our eyes and our hands and/or our feet to achieve fine motricity.
