Highlighting the Aspects to Support the Complexity of Primary Selection in Children's Alpine Skiing as a Sustainability of their Harmonious Development and Training

The extremely rapid evolution of portable technologies and children's receptiveness to constantly accessing the latest information creates the conditions for a number of new developments in most areas of activity. Moreover, their attraction to real-time visualisation of various events and competitions projects a certain level of perception and imitation of certain behaviours. Therefore, special attention should be paid to them from the earliest stages, i.e., from the time they are selected to play various sports. Also, the complementarity of some sports must be taken into account when it is desired to obtain positive results. Age group adaptation and the investigation of some of the parameters relevant to different age groups have generated values that can support positive outcomes in the long term and thus increase motivation to participate in sport at a competitive level.
