O objetivo do presente estudo foi caracterizar o desempenho da força muscular e da
agilidade em jovens jogadores de basquetebol nos diferentes escalões de formação em
Portugal. Participaram 73 jovens basquetebolistas do sexo masculino e feminino da
zona de Covilhã e Castelo Branco. Os jogadores estavam distribuídos por 3 escalões, 14
jogadores (11.52 ± 0.62 anos) e 9 jogadoras (11.43 ± 0.98 anos) pertenciam aos Sub 12
(U12), 15 jogadores (13.08 ± 0.59 anos) e 9 jogadoras (12.47 ± 0.80 anos) pertenciam
aos Sub 14 (U14), 15 jogadores (14.89 ± 0.73 anos) e 11 jogadoras (14.87 ± 0.68 anos)
pertenciam aos sub 16 (U16). A força dos membros inferiores e membros superiores foi
avaliada através salto com contramovimento e do lançamento da bola medicinal de 3kg,
respetivamente. A agilidade foi avaliada através do teste Line Agility Drill. Os
resultados demonstraram que não existiram diferenças entre U12 e U14 do sexo
feminino no lançamento da bola medicinal (do peito: p = 0.96, ES = 0.38; acima da
cabeça: p = 0.12, ES =0.75) e agilidade (p = 0.38, ES = 0.58), embora as jogadoras do
escalão U16 demonstrassem ser sempre superiores aos U14 e U12 em todas as variáveis
analisadas (p <0.01, ES = 1.07). No sexo masculino, os basquetebolistas mais velhos
demonstraram valores superiores de força nos membros inferiores, nos membros
superiores e de agilidade, com os U16 superiorizando-se aos U14 e estes aos U12 (p
<0.05, ES = 1.04). No que se refere à comparação entre géneros não existiram
diferenças de rendimento entre o sexo masculino e feminino na força e agilidade em
U12. Já nos escalões mais velhos, U14 e U16, foram encontrados valores superiores de
rendimento nas variáveis analisadas no sexo masculino, que parecem aumentar com a
idade (efeito moderado em U14; efeito grande a muito grande em U16). Com os
resultados obtidos, podemos concluir que o desempenho muscular no salto vertical,
lançamento da bola medicinal e agilidade, tende a ser superior consoante a idade,
podendo não existir diferenças nos escalões mais novos. A diferença na força dos
membros inferiores e superiores e na agilidade entre o sexo masculino e feminino
parece somente ser notória a partir dos 12 anos de idade, com valores superiores no
sexo masculino.
The aim of the present study was to characterize the performance of muscle strength and agility in young basketball players at different training levels in Portugal. 73 young male and female basketball players from the area of Covilhã and Castelo Branco participated in this study. The players were divided into 3 levels, 14 players (11.52 ± 0.62 years) and 9 players (11.43 ± 0.98 years) belonged to Sub 12 (U12), 15 players (13.08 ± 0.59 years) and 9 players (12.47 ± 0.80 years) belonged to the Sub 14 (U14), 15 players (14.89 ± 0.73 years) and 11 players (14.87 ± 0.68 years) belonged to the sub 16 (U16). The strength of the lower limbs and upper limbs was assessed countermovement jump (CMJ) and the launch of the 3kg medicine ball, respectively. Agility was evaluated using the Line Agility Drill test. The results showed that there were no differences between female U12 and U14 in the launch of the medicine ball (from the chest: p = 0.96, ES = 0.38; above the head: p = 0.12, ES = 0.75) and agility (p = 0.38, ES = 0.58), although the players of the U16 class always showed to be superior to the U14 and U12 in all analyzed variables (p <0.01, ES = 1.07). In the male gender, older basketball players demonstrated higher values of strength in the lower limbs, upper limbs and agility, with the U16 superior to the U14 and these to the U12 (p <0.05, ES = 1.04). Regarding the comparison between genders, there were no differences in income between male and female in strength and agility in U12. In the classes U14 and U16, higher values of income were found in the variables analyzed in the male gender, which seem to increase with age (moderate effect in U14; large to very large effect in U16). With this results, we can conclude that the muscular performance in the vertical jump, launch of the medicine ball and agility, tends to be higher according to age, and there may be no differences in the younger classes. The difference in the strength of the lower and upper limbs and in the agility between the male and female sex only seems to be noticeable after 12 years of age, with higher values in the male gender.
