Judo 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.
