Abstract(s)
A literatura do futebol geralmente explora os estudos voltados para a avaliação da
força. No entanto, os dados são limitados quando se considera a os diferentes níveis
competitivos, a idade, a posição em campo e a associação entre o desempenho da
dinamometria isocinética e os testes de salto vertical. Assim, o primeiro objetivo, era de
procurar analisar os indicadores de força e a sua variação associada à idade, nível
competitivo e posição em campo. Em relação ao segundo objetivo, temos que este é o de
investigar a relação entre o salto vertical e a avaliação da extensão e flexão do joelho
através do dinamómetro isocinético. Relativamente à metodologia, a amostra é composta
por 83 jogadores de 4 equipas de níveis competitivos diferentes, foram selecionadas para
análise as avaliações da dinamometria de mão, o countermovement jump (CMJ), o squat
jump (SJ) e a avaliação da flexão e extensão do joelho no dinamómetro isocinético. Para
efetuarmos as análises utilizamos o software SPSS v.21. Deste modo, podemos aferir que
os jogadores de nível competitivo superior e os jogadores mais experientes têm melhores
resultados no salto vertical e na potência média e que existe uma associação positiva entre
o CMJ e a potência média no isocinético.
Soccer literature generally explores studies aimed at assessing strength. However, data are limited when considering different competitive levels, age, field position and the association between isokinetic dynamometry performance and vertical jump tests. Thus, the first objective was to look for strength indicators and their variation associated with age, competitive level, and position on the field. Regarding the second objective, this is to investigate the relationship between the vertical jump and the evaluation of knee extension and flexion through the isokinetic dynamometer. Regarding the methodology, the sample is composed of 83 players from 4 teams of different competitive levels, estimates of hand dynamometry, the countermovement jump (CMJ), the squat jump (SJ) and the evaluation of flexion and extension were selected for analysis. of the knee in the isokinetic dynamometer. For the analysis we used the SPSS v.21 software. Thus, we can state that players with a higher competitive level and more experienced players have better results in vertical jumps and average power. There is a positive association between CMJ and average power in isokinetic assessment.
