JOURNAL FREE ACCESSJudo is one of the most widely practiced sports in the world. In the US, however, other sports like tennis, golf, or basketball are more popular. Consequently, there is very little judo-related renearch published in the contemporary scholarly literature, particularly in English. Research in other sports has shown that stress, confidence, and personality are important factors in predicting athletic performance, and this information has been used to help athletes perform better. This line of research is no less important for judo athletes. The prenent study is a first attempt to test whether anxiety, confidenc, and personality are related to performance in judo athletes. Elite and non-elite judo athleted measures assessing anxiety and confidence before competition. Elite athletes also completed a measure of personality and provied competitive performance data. Elite athletes also cfd more confidence than non-elite athletes and normative samples. Several psychological variables predicted performance measures and anxiety was correlated with less confidence in both elite and non-elite athletes. Applications of these results for both coaches and athletes are discussed.View full abstractDownload PDF (1212K) -

JOURNAL FREE ACCESSVisua function is regarded as important ability to kendo players. In order to clarify the effect of this visual function over kendo players of different level, we used sorts vision test to measure eight parameters, which include SVA (Static Visual Acuity), KVA (Kinetic Visual Acuity), DVA (Dynamic Visual Acuity), CS (Contrast Sensitivity), OMS (Ocular Motor Skill), DP (Depth Perception), VRT (Visual Reaction Time) and E/H (Eye/Hand Coordination).
For each parameter, we paritioned play level into 3 groups (higher, medium and lower group)depending on the player's capability. By means of statistical analysis and comparison of each experimental result, we conclude that.
higher group is superior to the others on SVA, KVA and E/H values. In addition, higher group's value is higher than those of medium group and lower group on CS and DP parameter, respectively.
It is concluded that, difference of skill of kendo players is involved with that of depth perception to sense space and distance, and coordination of eye with hand of the players.View full abstractDownload PDF (1274K) -

JOURNAL FREE ACCESSVisual acuity plays an important role in Kendo skills, however there are few studies of the systematic visual functions of Kendo players. We studied the visual acuity of male Kendo players in three groups (10 Kendo players designated by Japan Kendo Federation,11 college varsity players and 14 non-varsity players).
The visual acuity was estimated by measuring static visual acuity (SVA), kinetic vinual acuity (KVA), dynamic visual acuity (DVA), contrast sensitivity, eye movement, depth perception, visual reaction time (VRT), and eye-hand coordination. There was no statistical difference in all-visual parameters between designated and college varsity players. The eye-hand coordination of designated and college varsity players were better than college non-varsity players. The depth perception of college varsity players was better than that college non-varsity players. On the contrary, visual reaction time of non-varsity players was superior to that of varsity players whereas there was no significant difference between desiganted and college non-varsity players. There was significant correlation between SVA and KVA (r=0.669, p< O.001), contrast sensitivity (0.584, p<0.001). These results indicate that the eye-hand coordination may play an important role in Kendo performance.View full abstractDownload PDF (1268K) -

JOURNAL FREE ACCESSThe publishing conditions by the generation of books related to judo (jujutsu and self-defense are contained) published from Meiji first age to the 63rd year of Showa (1868-1988) and the place of their possession were investigated, and then it was the purpose of this research to put it in order in the list. It continues in the last time, this time, it is reported about those books published from the 21st year of Showa, by the 63rd year of Showa (1946-1988). As for the place of their possession, the following four places were investigated. National Diet Library, Kodokan Judo Library, Tsukuba University-Art & Physical Education Library, Minwa Library.
The totals of books related to judo published from the 21st year of Showa, by the 63rd year of Showa (1946-1988) were 382 as a result.View full abstractDownload PDF (5934K)
