  • Análisis del tipo de técnicas, puntuaciones y sanciones en el Campeonato de Europa de Judo Senior
    Publication . Silva Batista, Marco Alexandre; Escobar-Molina, Raquel; Fernandes, Jorge; Louro, Hugo
    Introducción: El judo es un deporte de combate olímpico dividido en categorías de peso y sexo. Los combates tienen una duración de cuatro minutos en ambos sexos, y cuando las puntuaciones o amonestaciones para ambos competidores son las mismas, se produce empate entre los judocas y el combate se decide mediante la Técnica de Oro. Es por ello que, la duración de los combates y de la competición, puede tener repercusiones en los judocas, tanto desde el punto de vista técnico, táctico, físico, fisiológico y psicológico, entre otros. Objetivo: El estudio tuvo como propósito determinar el predominio de las acciones técnicas, puntuaciones y penalizaciones en función de la duración del combate y la fase de la competición en el Campeonato de Europa de Judo Senior 2021. Metodología: Se observaron 398 combates en todas las categorías de peso y en ambos sexos (230 hombres y 168 mujeres). Para el registro de las técnicas se utilizó la clasificación Kodokan de judo. Se anotaron las puntuaciones y penalizaciones, a lo largo del combate y durante la Técnica de Oro, en las distintas fases de la competición. Resultados: La mayoría de los combates terminaron en el tiempo reglamentario (79,15%) y un menor porcentaje se resolvieron en la Técnica de Oro (20,85%). A medida que se avanza en la fase de competición hay una tendencia a que los combates se decidan mediante la Técnica de Oro. Conclusiones: El tiempo de combate y la fase de competición influyen tant o en el tipo de técnicas empleadas, las puntuaciones obtenidas y las penalizaciones recibidas.

  • Confirmatory factor analysis to validate the short version of the Ottawa mental skill for sports (OMSAT-3) in Portuguese athletes
    Publication . Silva, Carlos; Torres, Diana; Louro, Hugo; Borrego, Carla; Batista, Marco
    Introduction: The development of psychological skills plays an important role in improving performance and achieving excellent results in sports. Objective: The aim of this study was to validate the Portuguese short version of the Ottawa Mental Skills Assessment Tool (OMSAT-3). Methodology: By means of a confirmatory factor analysis (CFA), a total of 524 Portuguese athletes of both sexes aged between 12 and 42 (M = 19.21; SD = 5.46) were recruited for the present study. Results: The results indicate that the reduced version of the OMSAT-3 (30 items) has adequate psychometric qualities, enabling an assessment of Foundation, Psychosomatic and Cognitive Skills (SRMR = 0.052; CFI = 0.983; TLI = 0.979; RMSEA = 0.031 CI 90% [0.026, 0.037]; χ²/df = 1.52). There was high concurrent validity between the reduced version (30 items) and the full version (48 items). Conclusions: The results suggest that the reduced OMSAT-3 can be used with confidence to assess psychological skills in a sports context.

  • Effects of inclination in Farmer’s Carry: muscle properties and strength
    Publication . Machado, Renato Costa; Louro, Hugo; Freitas, João; Batista, Marco; Marinho, Daniel; Conceição, Ana
    Introduction: The farmer’s carry is a loaded‑carry exercise in which an individual walks a distance while holding heavy loads in each hand, requiring substantial grip strength, whole‑body stability, and coordinated lower‑limb force production. Objective: This study aimed to examine the acute effects of a light‑load inclined farmer’s carry protocol on grip strength, rectus femoris muscle mechanical properties, and lower‑limb asymmetries. Methodology: Twelve healthy young adults completed a continuous treadmill walk at 4 km/h while carrying two 10kg dumbbells, progressing through five incline stages (0–8%), each corresponding to 50 meters. Grip strength and muscle mechanical properties were recorded after each stage during a 1‑minute rest. Results: Significant grip strength reductions were observed in both hands, with decreases of 10.10% in the dominant side (p < 0.05, η²p = 0.61) and 8.50% in the non‑dominant side (p <0.05, η²p = 0.41). Also, a significant decrease in logarithmic decrement was detected in the dominant side (p = 0.04, W = 0.19). At baseline, 0, 2 and 6% were also observed significant differences between the dominant side and non-dominant side in logarithmic decrement. Conclusions: Overall, inclined farmer’s carry efforts primarily induced peripheral, grip‑specific fatigue, with minimal alterations in rectus femoris muscle mechanical properties, supporting the use of inclines to safely increase task difficulty without excessive mechanical stress.
