[en] The present study investigated the limb symmetry index (LSI) and the relationship between different functional strength tests in young elite judokas. Seventeen males (age= 16.88±1.40 years, height= 179.00±7.00 cm, weight= 78.76±15.22 kg and BMI 24.40±3.36 kg/m2) participated in the study voluntarily. Participants were tested with single leg (SL), and triple leg (THD) hop for distance, crossover hop for distance (CHD), 6 m Timed Hop Test (6mTHT), and single-leg vertical jump (SLVJ) tests, and countermovement jump (CMJ). All SL hop tests (SLHT) were applied to both right (Rs) and left sides (Ls), while CMJ was applied as without (CMJWAS) and with arm swing (CMJAS). Paired sample t-test and Pearson correlation tests were used in statistical analyses. In all SLHTs, no statistical significance was found between Rs and Ls. However, significance was found between CMJWAS and CMJAS. There was also no significance in LSIs between all SLHTs. Correlations were found between SL, THD, CHD, VJ tests, while negative and significant correlations were found between SL, THD, CHD, VJ tests, and 6 m THT. No significance was found between SLHTs and CMJWAS and CMJAS. As a result, it was found that Rs and Ls of young judokas produced similar strength in SLHTs, while they caused differences in CMJWAS and CMJAS values; when evaluated in terms of LSI, judokas showed similar rates in all SLHTs, and these rates were within reliable ranges; SLHTs had correlations with each other, but they did not show any correlation with CMJ.

[pt] O presente estudo investigou o índice de simetria dos membros superiores e inferiores (IEL) e a relação entre diferentes testes de força funcional em jovens judocas de elite. Dezassete indivíduos (idade= 16,88 ± 1,40 anos; altura= 179,00 ± 7,00 cm; peso= 78,76 ± 15,22 kg; e IMC 24,40 ± 3,36 kg/m2) participaram voluntariamente no estudo. Foram avaliados por meio de vários testes: single hop test (SL), triple hop test (THD), crossover hop test (CHD), 6-m hop test (6mTHT), salto vertical de perna única (SLVJ) e salto com contramovimento (CMJ). Todos os SL hop test (SLHT) foram aplicados, tanto na perna direita (Rs), como na perna esquerda (Ls), enquanto o CMJ foi aplicado sem (CMJWAS) e com braço swing (CMJAS). O t-test de amostras emparelhadas e o teste de correlação de Pearson foram usados nas análises estatísticas. Em todos os SLHTs, não foram encontradas diferenças significativas entre as duas extremidades. No entanto, foram encontradas diferenças entre CMJWAS e CMJAS. Também não houve diferenças no LSI entre todos os SLHTs. Foram encontradas correlações entre os testes SL, THD, CHD, VJ, e correlações negativas e significativas foram encontradas nos testes SL, THD, CHD, VJ e THT 6 m. Nenhuma diferença foi encontrada nos testes SLHT e CMJWAS e CMJAS. Consequentemente, verificou-se que os membros inferiores dos jovens judocas produziram uma força semelhante no SLHT, enquanto ocorreram diferenças nos valores de CMJWAS e CMJAS. Quando avaliados em termos de LSI, os judocas mostraram taxas semelhantes em todos os SLHTs, e essas taxas estavam dentro dos intervalos de confiança. Os SLHTs foram correlacionados entre si, mas não apresentaram correlação com o CMJ.
