The COVID-19 pandemic has caused governments to establish quarantine and social distancing for the population in order to decrease the contamination peak, factors that have affected the athletes' preparation. In this context, we developed some high-intensity interval training (HIIT) recommendations for Olympic combat sports athletes that can be performed at home. The HIIT protocols should be added by body mass-based muscle strengthening exercises (similar to technical exercises), with the goal to preserve athletes' muscle mass and physical fitness. Finally, emergency situations require contingency plans for sport. ; La pandemia del COVID-19 ha obligado a los gobiernos decretar cuarentena y aislamiento social en la población con la intención de aplanar la curva de contagio, hechos que han afectado de igual modo la preparación de los atletas. En dicho contexto, hemos desarrollado algunas recomendaciones de entrenamiento intervalado de alta intensidad (HIIT) que podrían ejecutar atletas de deportes de combate olímpicos en sus hogares. Los protocolos HIIT debiesen complementarse con ejercicios de fortalecimiento muscular con el propio peso corporal (similares a los ejercicios técnicos), con la intención de conservar la masa muscular y la condición física de los atletas. Finalmente, situaciones de emergencia requieren planes de contingencia en el deporte. ; A pandemia de COVID-19 tem obrigado os governos a decretarem quarentena e isolamento social para a população com a intenção de achatar a curva de contágio, ações que têm afetado a preparação de atletas. Neste contexto, desenvolvemos algumas recomendações de treinamento intervalado de alta intensidade (HIIT) que os atletas de esportes de combate olímpicos poderiam executar em seus lares. Os protocolos de HIIT devem ser complementados com exercícios de fortalecimento muscular com a própria massa corporal (similares aos exercícios técnicos), com a intenção de preservar a massa muscular e a condição física dos atletas. Por fim, situações de emergência requerem planos de contingência no esporte.

The aim of this study was to evaluate Special Judo Fitness Test (SJFT) results specific to the population of male judoka and to develop age category norms for junior and senior athletes. A systematic review of the existing literature was conducted to identify 281 publications reporting SJFT results between 1995 and 2018. The final meta-analysis included data from 37 relevant studies that reported SJFT results from 51 individual samples of 515 senior and 209 junior male athletes. The combined mean and SD for SJFT variables were calculated, and the Cohen's d effect size with 95% confidence intervals (CI) for the senior and junior age classifications were compared. Senior athletes demonstrated higher total number of throws (d = 0.41, CI = 0.25–0.57, p <0.001) and heart rate (HR) immediately after the SJFT (d = 0.18, CI = 0.02–0.35, p = 0.025) with limited differences for HR one minute after the SJFT between groups. The SJFT index was lower for seniors compared to juniors (d = 0.38, CI = 0.22–0.54, p <0.001) indicating better overall performance by the more advanced athletes. Percentile rankings were used to develop SJFT classificatory tables for male senior and junior judo athletes. Training staff can use the age group classifications in the evaluation process of their athletes and for the purpose of monitoring training.

The aim of this study was to examine changes in body mass (BM) and power-related measures in Olympic boxers during an official qualifying boxing tournament. Fourteen elite amateur boxers from the Brazilian National Team (eight men and six women) participated in this study. Athletes performed three fights in four days against the same opponent of the same weight-category. Before and immediately after every fight, BM, countermovement jump (CMJ) height, and power production in the bench-press and half-squat exercises were assessed in the same order and on the same time of the day. A two-way repeated-measures ANOVA with the Bonferroni post-hoc analysis was used to determine the variations between pre- and post-measures. The statistical significance was set as p < 0.05. The athletes were able to maintain their baseline weight and physical performance throughout the experimental period, as shown by the lack of significant changes in BM, CMJ height, and upper- and lower-limb power output. Throughout a four-day qualifying tournament, the BM and power-related performance of Olympic boxers were not affected either by match execution or by successive matches. As scoring actions are highly dependent on muscle power, it is likely that these combat athletes are able to maintain optimal levels of performance across consecutive matches.
