“…Ribeiro et al 7 had used a Biodex machine to register 71 N.m at 90°/s in Brazilian elite judo players. Similarly, Silva et al 8 noted 87 N.m at 90°/s in Brazilian Paralympics team. Accordingly, Ichinose et al 9 assessed elbow extensors at 60°/s in Japanese national judo team using a cybexII, he found a significant difference in maximum PT (215 N.m versus 188 N.m) in the dominant arm.…”

“…Accordingly, Ichinose et al 9 assessed elbow extensors at 60°/s in Japanese national judo team using a cybexII, he found a significant difference in maximum PT (215 N.m versus 188 N.m) in the dominant arm. The ratio concentric external/internal rotators was higher in the non-dominant side 45% versus 35, p<0.05), because of the high strength of internal rotators in judo 7,8 .…”

Background: it is well established that muscle strength is a determinant factor in judo. However, little data are available for African athletes. Therefore, the aim of this study was to provide reference data of the muscular strength profile (MSP) for an African team, Tunisian judo team. Methods: the study was conducted among ten international judo athletes from Tunisia. To determine their MSP, we used an isokinetic dynamometer to assess Hamstrings, Quadriceps of both knees and external, internal rotators of both shoulders. The angular velocities of the assessments were; 90, 180, 240°/s for the knees and 60, 120°/s for the shoulders. Results: MSP was determined based on two parameters; the maximum peak torque (PT) of each muscle and the ratio agonistic/antagonistic muscles (R). The knee extensors and flexors in the "supporting leg" had higher PT than in the "attacking leg"; respectively, 245N.m versus 237 (p<0.05) and 147 N.m versus 145 (p>0.05). R was normal for both legs. Furthermore, both rotators of the dominant shoulder had higher PT; 84 N.m versus 71 for the internal rotators (p<0.05) and 34,7 N.m versus 29,0 for the lateral rotators (p<0.05). Inversely, R was higher in the non-dominant side; 45% versus 35, p<0.05). Conclusion: the MSP of the selected elites Tunisian judo athletes was characterized by 3 major features; a strength of the quadriceps in the standing leg significantly higher than in the attacking leg, a normal muscular balance Hamstrings/quadriceps in both legs and a strength of the shoulder' rotators higher in the dominant side.

“…Assim como para as variáveis da composição corporal, as variáveis do desempenho motor também foram analisadas de acordo com a função exercida em campo por cada jogador, das quais foram encontradas diferenças significativas dos Goleiros com Meias, Atacantes e Alas (p=0,002; 0,022; 0,005), e dos Meias com Atacantes (p=0,015) na potência média. A força máxima é essencial para a performance da potência (Ronnestad, Kvamme, Sunde, & Raastad, 2008), e visto que pessoas com PC possuem um déficit de força muscular (Damiano & Abel, 1998;Krigger, 2006;Silva & Andrade, 2002), acredita-se que o grau de acometimento nos membros inferiores nos Goleiros possam ter contribuído para resultados. No caso dos Meias atingirem melhores resultados que os atacantes, o mesmo pode ser levado em consideração, visto que os Meias, neste estudo, possuem atletas com menor grau de acometimento (Tabela 1).…”

Introdução: O futebol de 7 é um esporte intermitente no qual a capacidade de força é evidenciada, tornando a avaliação desta e outras capacidades essenciais para o alcance do desempenho esportivo. Objetivo: O objetivo deste estudo foi identificar o perfil antropométrico e do desempenho motor, por classe funcional e posição de atletas da seleção brasileira de futebol de 7. Metodologia: A amostra foi composta por 16 atletas. Na avaliação antropométrica foi medido: MC, estatura, IMC, pregas cutâneas e circunferência abdominal. Para o desempenho motor foram utilizados: saltos verticais, agilidade 10 x 5 e RAST test. Resultados: As variáveis antropométricas apresentaram média da MC de 69,6±7,3, IMC de 19,9±1,9, somatória de nove pregas 88,8±35,4 e %G 10,6±5,4. O desempenho motor apresentou resultados para agilidade de 18,9±1,1, Countermovement jump 33,4±8, Squat jump 31,6±7,6 e potência média 6,3±1,5. Conclusão: Os resultados se apresentaram adequados para atletas de alto rendimento e o desempenho motor sofreu influências da classe funcional.

“…Isokinetic dynamometers are among the tools that enable us to evaluate skeletal muscles which allow different joints to make movements and the strength produced by these muscles in the most objective way. 11,12 At the same time, it is possible to find out whether muscle groups are prone to injury with isokinetic dynamometers. 13,14 Especially in combat sports, performing muscle strength tests is important in terms of revealing the possible differences and asymmetry between muscle groups.…”

Background and purposeMuscle strength is one of the most physically important parameters during the competition for judokas. Studies have shown that for judokas, strength in especially the knee and shoulder muscles and the strength balance between right and left sides is very important in terms of both staying in balance and doing specific techniques correctly. Our study aims to find out the correlations between isokinetic lower and upper extremity strength in elite judokas and to examine bilateral and contralateral strength ratios. MethodsThis study is designed according to cross-experimental design with randomized repeated measurements. Fifteen male (mean values: age 19.40 ± 1.24 years, height 170.55 ± 9.44 cm, weight 78.47 ± 18.55 kg, and BMI 27.02 ± 5.82 kg/m 2 ) elite judokas between the ages of 18 and 21 participated voluntarily in the study. Knee extension (EX) and flexion (FLX), shoulder internal rotation (IR) and external rotation (ER) isokinetic strength measurements of the subjects were measured with concentric/concentric (Con/Con) contractions at 60 o s -1 and 180 o s -1 angular velocities. Ipsilateral hamstring/quadriceps (H/Q), internal rotation/ external rotation (IR/ER), contralateral Q/Q, H/H, IR/IR, ER/ER ratios were calculated through lower and upper extremity isokinetic strength. Shapiro-Wilk, Levene, paired sample t-test, and Pearson correlation test were used in statistical analyses. ResultsIn terms of the ipsilateral strength ratios on dominant (DS) and nondominant (NDS) in lower and upper extremities, a significant difference was found only at 60° s -1 angular velocity in only the lower extremity on DS (P < 0.05). In contralateral strength ratios, a statistically significant difference was found between Q/Q and H/H at 60° s -1 angular velocity (P < 0.05). When the correlations between lower and upper extremities Correlation of upper and lower extremities isokinetic strength in elite male judokas e142
