Detecção de talentos para o voleibol na escola: uma modelagem estatística baseada na estatura adulta prevista

Abstract

The detection of sports talent is an important area of study in sports science. Although there is still much evidence today, there are many countries that invest in these programs because they consider detection to be the first stage in the formation of a high-performance sports athlete. In volleyball, he did not find a model in Brazil that meets this stage of detecting young athletes for the school context, where we find the greatest number of young people. It observes the height as the main variable for the modality and its prediction with the executed maturational aspects, important data in the process of promoting athletes of performance. This study aimed to present an innovative proposal for detecting talent for volleyball, based on the variable predicted adult height (EAP). From the sample of students from the Military College of Juiz de Fora of both sexes (1060 in total), aged between 12 and 16 years, analyzed the assessment of height, weight and average height of the parents, were the predicted adult height. , mean and standard deviation. With data from the 2019 Superliga A volleyball players and players, they were measured as average heights by game position, setter (185.0 cm) and (174.0 cm), pointer (192.0 cm) and (179 , 0 cm), central (200.0 cm) and (185.0 cm), opposite (198.0 cm) and (181.0 cm) and libero (179.0 cm) and (161.2 cm), male and female respectively, being the biggest of the central position players, followed by opposites, pointers, setters and liberos. As results found that only 4.3% of the boys obtained can reach the height of elite athletes in the sport and 2.2% of girls. The number is even smaller when observed in game positions, where, according to the average heights forecast, boys and girls have 58.3% and 58.4% of reaching the height of players in the libero position, respectively, followed by a higher percentage for lifters 13.3% for boys and 4.8% for girls reach the average height of elite athletes. For opposite centers and pointers the values were very small, less than 1%. It is concluded that an expected adult height can be an important instrument to detect young talents for volleyball in order to promote high performance athletes. The new proposed model is of wide applicability and reproducibility. in the findings.
