Relação entre agilidade, potência, índice de massa corporal e somatótipo de crianças e adolescentes praticantes de voleibol residentes no Rio de Janeiro

Abstract

During childhood and adolescence, body changes occur that can exert positive or negative influences on the performance of motor tasks. The objective of the present study was to verify the relationship between morphological profile and motor proficiency of children and adolescents who practice volleyball living in the city of Rio de Janeiro. The study followed the Scandinavian format, conducting two studies to reach its conclusion, the first systematic review study that aimed to identify the relationship between anthropometric and motor characteristics (agility and vertical impulsion) of children and adolescents practicing volleyball. It was observed at the end of the study that the application of anthropometry is limited to identifying and comparing profiles, not relating it to sports performance. No studies were found that correlated anthropometry with agility. The second study had a quasi-experimental character and a sample of 299 children and adolescents of both sexes between 07 and 14 years old. The individuals underwent an anthropometric assessment (body mass, height, body mass index and somatotype) and a motor assessment of agility (item 1 of subtest 1 of the Bruininks-Oseretsky motor proficiency test) and lower limb strength (test vertical thrust). When verifying the relationship between morphological profile and motor proficiency of children and adolescents practicing volleyball, it was observed that the anthropometric variables of height and body mass are the ones that change the most when compared between the different age groups and when correlated with the motor variables. Thus, it is necessary that the professional responsible for conducting the activity and training of children and adolescents is able to identify and respect the peculiarities of each age group, not taking into account only chronological age but also their motor capacity, minimizing evasion and encouraging participation. and adherence of the child to the proposed activity.
