AIMS Analyze the epidemiology and the distribution of judo injuries in a pediatric population. PATIENTS AND METHODS A retrospective study was conducted from May 2006 to May 2008, including all patients aged less than 15 years admitted to a tertiary-level pediatric emergency unit. The data collected were age, sex, geographic origin, time and day of admission, duration in the pediatric emergenc...

The objective of this study was to examine the effect of caffeine on judo performance, perceived exertion, and plasma lactate response when ingested during recovery from a 5-day weight loss period. Six judokas performed two cycles of a 5-day rapid weight loss procedure to reduce their body weight by ~5%. After weigh-in, subjects re-fed and rehydrated over a 4-h recovery period. In the third hou...

The aim of the present study was to investigate whether preexercise sodium-bicarbonate ingestion improves judo-related performance. The study used 2 different protocols to evaluate performance: 3 bouts of a specific judo test (n = 9) and 4 bouts of the Wingate test for upper limbs (n = 14). In both protocols athletes ingested 0.3 g/kg of sodium bicarbonate or placebo 2 h before the tests. Blood...

The purpose of this study was to investigate the effects of concurrent training on oxidative stress biomarkers in judokas, as well as to compare the effects of such training on performance characteristics in relation to usual training programs. A total number of 14 male judokas were divided into two groups: experimental (E) and control (C). Over 12 weeks, subjects from E group were included int...

This study has been performed to reveal hand bone peculiarities of elite male judoists by comparing their phalangeal and metacarpal bones with those of sedentary men on the basis of biometric ratio of the bones by means of three-dimensional (3D) reconstruction of multidetector computed tomography (MDCT) images. For this purpose, the axial images of the right and left hands of 8 elite male judo ...

In Paralympic judo for athletes with vision impairment (VI judo) all eligible (i.e. B1, B2 and B3 classes) compete against each other in the same competition. Evidence suggests that more may be disadvantaged, but sensitive measures of performance are necessary to understand impact on performance. The aim this study was investigate relationship between Para sport class technical variation, time-...

The train came out of the long tunnel into the snow country.-Yasunari Kawabata PRESCRIPT Nothing is more dramatic than running out of time and uncertainty. The fear of drama can be finally overcome by embracing the permanence of death bringing to an end the disease of life. However, the attempt to eliminate all risk has its own risks. Because of Japan's rich literary legacy, its relationship wi...

The aim of the study was to assess the impact of motor abilities and morphological characteristics on junior judoka performance. A set of 14 morphological parameters and a set of 14 motor tests as predictor variables, and 3 variables evaluating judo performance as criteria were applied in a sample of 40 judoists aged 17 years +/-6 months. Three factors were isolated by factor analysis in morpho...

Most severe head injuries in judo are reported as acute subdural hematoma. It is thus necessary to examine the rotational acceleration of the head to clarify the mechanism of head injuries. We determined the rotational acceleration of the head when the subject is thrown by judo techniques. One Japanese male judo expert threw an anthropomorphic test device using two throwing techniques, Osoto-ga...
