    Publication . Silva, Carlos; Torres, Diana; Louro, Hugo gonçalo Duarte; Borrego, Carla; Batista, Marco
    The aim of the study was to validate the Portuguese version of the Ottawa Mental Skills Assessment Tool (OMSAT 3p) through confirmatory factor analyses of the measurement model, and gender invariance. A total of 524 Portuguese athletes (male and female) aged between 12 and 42 years old, participated in this study (M = 19.21; SD = 5.46). The main results show that the psychometric qualities of the 48-item OMSAT 3 are adequate and that it has acceptable validity, allowing it to assess Foundation Skills (SRMR = 0.042, CFI = 0.999, TLI = 0.998, RMSEA = 0.008 and χ2 /df = 1.46), Psychosomatic Skills (SRMR = 0.056, CFI = 0.979, TLI = 0.975, RMSEA = 0.042 and χ2 /df = 1.93) and Cognitive Skills (SRMR = 0.058, CFI = 0.973, TLI = 0.968, RMSEA = 0.044 and χ2/df =1.99). This version also showed adequate values for configural, metric and scalar invariance by gender (ΔCFI < 0.01) (ΔRMSEA<0,01). The Portuguese version of the OMSAT 3 can be used with reasonable confidence to assess psychological skills in a sports context.
  • Predominant technical actions used in the European judo championship
    Publication . Batista, Marco; Silva, Carlos; Torres, Diana; Conceição, Ana; Borrego, Carla; Louro, Hugo Gonçalo Duarte
    Judo is an Olympic combat sport that is divided into male and female weight categories. Each weight category implies significant differences in technical and strategic dimensions, as well as physiological, performance, and body composition among com- petitors. This study aimed to determine the technical actions predominance used by judokas in the European Judo Championship 2021. We observed 398 judo combats, in the various weight categories male and female, disputed in the European Judo Championship 2021. It was used an observation system in accordance with the classification of judo techniques proposed by Kodokan. An observation system was used according to the Kodokan classification of judo techniques. In Nage-Waza combat, there was a predominance leg technique (Ashi-Waza), arm technique (Te-Waza), hip technique (Koshi-Waza), side sacrifice techniques (Yoko-Sutemi-Waza) and frontal sacri- fice techniques (Ma-Sutemi-Waza). When we focused our observation on the effectiveness of applied techniques, we observed more techniques scored with Ippon than Wazari. We can also observe that Shido was the significantly more recurrent punishment during male combats.

    The interest of this study perspective, which allows us to interpret competitive action in more detail, is also important to reflect that according to the legal adaptations dictated by the rules of a modality, it makes its study necessary. The objective was to analyse the predominance of technical actions used in the 2021 European Judo Championship based on combat time and golden score. The study sample focused on 400 combats of the European Judo Championship 2021. We used an observation system created for this purpose, according to the classification system proposed by Kodokan. Cross-frequency tables were produced, where the association degree between variables was analysed using the Chi Square test, where the significance level was set at p ≤ .05. We complemented the association analysis between variables by calculating the adjusted standardized residuals. The predominance of techniques and their effectiveness presented a similar hierarchy in both the combat and golden score phases. In golden score, women showed a significant association with hip techniques and men with frontal sacrifice techniques. Female athletes proved to be more effective in percentage terms in the golden score phase.
