Abstract: the aim of this study was to analyze the judo specific tests present in the literature, including the variables obtained from these and their use as performance markers in judo matches. to develop of this study we considered original articles indexed from 1990 to 2011, using electronic data bases scopus?, scielo?, sciencedirect? (elsevier) and pubmed?. the keywords used for research were: judo, performance, aptitude tests and their combinations. after analyzing the articles deemed eligible, we elected four tests (studies) that considered all criteria: a) special judo fitness test (sjft), b) endurance test of azevedo et al. (2007), c) uchikomi fitness test - uft and d) santos test. all tests have the judo motor skills for the identification of physiological variables, however, its use depends of the researcher's purpose. the sjft can be used for the identification of anaerobic and aerobic capacity as well as being able to induce glycolytic and aerobic demand similar in the judo match. the azevedo et al. endurance test needs a validation process based in the gold-standard to maximal lactate steady state to be a reliable tool in the obtain the aerobic capacity. the uft and the santos test reproduce some judo match characteristics, but still need more original studies to be considered as performance markers.

Abstract: this study evaluated force and velocity parameters of vertical jump performance in countermovement jump (cmj) and squat jump (sj) and compared results for sprint runners and volleyball players. twenty-four male athletes (12 regional/national-level sprint runners and 12 national-level volleyball players) performed cmj and sj on a force platform. the following variables were analyzed: jump performance (jump height and power), peak velocity (pv), absolute and relative maximum force (mf), rate of force development (rfd,) and time to reach maximum force (tmf). in cmj, jump height was correlated with pv (r=0.97) and normalized mf (r=0.47), whereas jump power was significantly correlated with all variables, except mf (r=0.12). in sj, pv and normalized mf were significantly correlated with jump height (r=0.95 and r=0.51) and power (r=0.80 and r=0.87). in addition, tmf was inversely correlated with power (r=-0.49). runners had higher performance variables (height and power), normalized mf and pv than volleyball players in both cmj and sj. velocity and maximum force were the main determinants of height and power in the two types of vertical jumps. however, explosive force (rfd and tmf) was also important for power production in vertical jumps. runners had a better vertical jump performance than volleyball players.

Motricidade , 2011, DOI: 10.6063/motricidade.7(2).112
Abstract: This study aimed to analyze the impact magnitude in the lower limbs during the landing phase in handball jump throw as well as to relate the impacts with the body weight (BW), jump height (JH) and the knee flexion angle (KA) and hip flexion angle (HA) during landing. Nine handball athletes, aged 22.2 ± 1.4 years took part in this study. A triaxial accelerometer was used to analyze the knee and ankle impacts. Kinematics parameters were investigated using a three-dimensional system. Descriptive statistics, analysis of variance and linear multiple regression set at 5% were used. The highest impact magnitudes occurred in the anteroposterior axis of the knee (28.24 g) as well as in the ankle (59.81 g) with 71% of the knee impact explained by HA and BW while 45% of the ankle impact were explained by HA and KA. Results allow for the conclusion that hip flexion had the highest influence on the lower limb impact whereas there was no observed influence of jump height. Therefore, correct landing technique can minimize the overload applied to the athlete’s joints. Este estudo objectivou analisar as magnitudes dos impactos nos membros inferiores de atletas de andebol durante a recep o ao solo no remate em suspens o e relacioná-las com massa corporal (MC) dos atletas, altura do salto (AS) e angulos de flex o do joelho (AJ) e do quadril (AQ) na recep o. Participaram nove atletas de andebol com idade de 22.2 ± 1.4 anos. Foi utilizado um acelerómetro triaxial para análise dos impactos no joelho e no tornozelo e um sistema de reconstru o tridimensional de movimento para análise cinemática do AQ, AJ e AS. Utilizou-se estatística descritiva, análise de variancia e regress o linear múltipla, com significancia de 5%. As maiores magnitudes de impactos ocorreram no eixo antero-posterior, tanto no joelho (28.24 g), quanto no tornozelo (59.81 g); 71% do impacto no joelho pode ser explicado pelas variáveis AQ e MC; 45% do impacto no tornozelo pode ser explicado pelas variáveis AQ e AJ. Conclui-se que o angulo de flex o do quadril foi a variável mais determinante nos valores de impactos nos membros inferiores, enquanto a altura do salto parece n o ter influência, mostrando que o domínio da técnica correcta de recep o ao solo pode minimizar as sobrecargas aplicadas no organismo dos atletas.

Abstract: The aim of this study was to identify force and velocity parameters related to vertical jump performance in counter movement jump (CMJ) and squat jump (SJ), and to compare these parameters between sprint runners and volleyball players. Twenty-four male athletes (12 regional/national-level sprint runners and 12 national-level volleyball players) participated in this study. The athletes performed CMJ and SJ on a force platform. The following variables were analyzed: jump performance (jump height and power), peak velocity (PV), absolute and relative maximum force (Fmax), rate of force development (RFD,) and time to reach maximum force (TFmax). In CMJ, jump height was correlated with PV (r=0.97) and normalized Fmax (r=0.47), whereas jump power was significantly correlated with all variables, except for Fmax (r=0.12). In SJ, PV and normalized Fmax were significantly correlated with jump height (r=0.95 and r=0.51, respectively) and power (r=0.80 and r=0.87, respectively). In addition, TFmax was inversely correlated with power (r=-0.49). Runners presented higher performance variables (height and power), normalized Fmax and PV than volleyball players in both CMJ and SJ. In conclusion, velocity and maximum force were the main determinants of height and power in the two types of vertical jump. However, explosive force (RFD and TFmax) was also important for power production in vertical jumps. Finally, runners presented a better vertical jump performance than volleyball players.

Revista Brasileira de Cineantropometria e Desempenho Humano , 2009,
Abstract: The purpose of this study was to investigate kinematic characteristics and impact of the handball jump throw. Nine male athletes of the university team participated of this study. A tri-axial accelerometer was used for identify the impact magnitude of the lower limb and the three-dimensional analysis system DMAS 5.0 was used for the analysis knee and hip angle of the jump throw. The kinematic and accelerometry dates were simultaneously collection. Reflective markers were placed on the anatomic landmarks of the athletes and the accelerometer was placed on the knee and ankle. For the date analyses, descriptive statistics, analysis of variance and Pearson correlate were used. The level of significance was set at 5% for all tests. The biggest impact magnitudes were acquired of the anterior-posterior axle on the ankle joint (58.81 g). Knee and hip angle in the contact with ground were lesser than knee and hip angle in the maximum flexion of the lower limb (27.24o and 33.75o for knee and 25.77o and 26.77o for hip), respectively. The impact magnitude in the knee of the anterior-posterior axle showed inverse correlate with the knee (r= -0.64; p= 0.05) and hip angle (r= -0.77; p= 0.01) in contact with ground. From results can be conclude that, although this team to be amateur, is necessary improvement of jump throw technique to decrease of cumulative effects of overload by long time of training.

Abstract: LOMBARDI, G.; VIEIRA, N. S.; DETANICO, D. Effect of two types of power training in the vertical jump performance in volleyball players. Brazilian Journal of Biomotricity. v. 5, n. 4, p. 230-238, 2011. The aim of this study was to analyze the effect of two types of strength training (plyometric and weightlifter) in vertical jump performance in volleyball athletes. Sixteen female athletes (13 to 14 years) took part of this study. They underwent a training period of 4 weeks with a frequency of three days per week. We used three distinct groups to sample: plyometric group (PG; n=5), weight training group (WG; n=6) and control group (CG; n=5) that did not participate in specific training for power. The athletes were evaluated for the Counter Movement Jump (CMJ). The t-test for dependent samples and analysis of variance (ANOVA one way) with Tukey test were used with level of significance set at 5%. The results showed significant increase in the vertical jump of WG between pre and post-test (p < 0.05). When analyzing the three groups (PG, WG and CG), no significant differences (p > 0.05) was showed, indicating that the three methods can be used for power training for athletes analyzed.

Abstract: This study aimed to identify the height obtained in the power of lower limb in soccer and futsal players, comparing the counter movement jump (CMJ) among the modalities, game positions and categories. Took part of the study 61 soccer athletes from under-17, under-20 and professional categories and 28 futsal athletes from the under-20 and professional categories. It was used a piezoelectric force platform Quattro jump. It was used descriptive statistics, student “t” test and analysis of variance set at p < .05. No significant difference was reported in the CMJ between the soccer and futsal athletes (p = .85). Among the positions adopted by soccer players it was found significant difference (p = .02) only between those in defensive positions and those in the midfield. In the futsal athletes it was not reported significant difference between positions (p = .69). Compared to other categories no significant differences were found, neither in soccer (p = .12) nor in futsal (p = .47). It can be concluded that the soccer and futsal athletes seems to present similar level of muscle power. Those in defensive positions presented higher levels of power when compared to those in the midfield, but in futsal the athletes presented similar power levels. Independent of the category, both soccer and futsal athletes presented similar level of muscle power.
