Abstract: [b]Background & Study Aim. [/b]This study aimed to further knowledge of: 1) body stance side preferred in performing tachi-waza (fighting in standing position); 2) level of fitness preparation of males and females; 3) effect of the dominant body side on the quality of performance in SJFT and the effort perceived. [b]Material & Methods[/b]. Paired selection helped obtain the consistency of the characteristics of 9 male and 9 female subjects in terms of age (Males 18.0 2.3 vs. Females 17.2 2.3 years), training experience (9.9 1.7 vs. 10.7 2.9 years), sports skill level (1-2 dan) and another weight category. A dominant fighting stance (right or left) was determined. In another two days, the randomly selected subjects performed SJFT with the dominant and non-dominant body side. The data grouped according to the body side formed the condition factor. The analysis used non-parametric statistical tests. The differences were tested at the significance level set at p<0.05. [b]Results[/b]. Distribution of the group sizes for left- and right-sided subjects in groups of males and females did not differ (p=0.667). Performing the throws in series A of SJFT with the dominant vs. non-dominant body side showed significantly better results in males (p=0.030), but not in females (p=0.424). Evaluation of the similarity of performing SJFT with the non-dominant body side in a judo bout during competition was significantly higher in males compared to females (p=0.015). [b]Conclusions.[/b] The throws used during SJFT are most frequently performed using the dominant compared with the non-dominant body side, but the females are characterized by a specific pattern of performing consecutive series of SJFT compared to men. Women feel higher fatigue when performing the test using the non-dominant body side.

Abstract: [b]Background and Study Aim.[/b] At the moment to select training means for composing the training program, many coaches are guided by the empirical evidence of training means specificity. A practical and scientific instrument containing relevant judo training means may contribute to coaches to achieve better results. The purpose of this study was to elaborate a catalogue of judo training means and classify it according to specificity: general, special or specific. [b]Material and Methods[/b]. Five Brazilian judo coaches answered what exercises are used for training the judo demand. The exercises were combined to a physical training method generating training means and it were submitted to 9 experts who evaluated the practical relevance and the specificity of each training mean to form the catalogue. The Coefficient of Validity Content and the Coefficient of Kappa were used as a statistical tool to measure the practical relevance of the catalogue and the classification of specificity, respectively. [b]Results. [/b]Seventy six exercises were listed and suitable to training means. Coefficient of Kappa value was = 0.533. Twenty two training means were classified as general, sixteen as special and thirty eight as specific of judo. The Coefficient of Validity Content for the catalogue was = 0.821. Analyzing this coefficient by specificity, the group of specific training means achieved the higher rate and the general group had the lower rate. [b]Conclusion.[/b] A catalogue of training means for judo were elaborated and classified by specificity. The high rate found for practical relevance confirm the representatively of this catalogue.
