PHYSICAL ACTIVITY AND EVOLUTIONARY CHANGE OF MOTOR SKILLS IN SCHOLAR AGE

Reducing physical activity is a phenomenon that not only affects the adult population, but also young people since the preschool age, resulting in a change in the evolution of motor patrimony and physical efficiency. The interest in international literature is centered on obesity and loss of aerobic performance, which are the main health risk factors, while surveys of motor capacity are still very limited. The present study investigated the evolutionary tendency of motor skills, trying to extract relevant information from a series of researches in different countries around the world for an interpretative analysis of theoretical and documental results. This trend is worrying as it seems to affect the natural development of motor performance during the evolutionary age. The results of these studies reflect on the importance of a broad set of physical and coordinative efficiency, developed optimally to ensure further growth in motor performance over time. This also implies a reflection on the opportunity of early learning of technical skills that, if not supported by a broad base of capabilities, could then cause performance stagnation. In the final part of the article, operational some suggestions are proposed to pursue the objective of developing a broad base of motor skills, integrating quantitative parameters, whose modulation has direct effects on physical efficiency, and the qualitative parameters, the modulation of which serves to enrich the baggage of motor skills useful to the solution of ever-new engine tasks. Key words: physical inactivity, motor strength, physical efficiency, ecological and cognitive approach
