ABSTRACT
ABSTRACT Introduction Good flexibility is one of the foundations for developing a high level of exercise. Flexibility training in martial arts mainly focuses on flexibility training of the abdominal center and upper and lower limbs. Objective Explore the effect of strengthening the abdominal center on flexibility in martial arts athletes. Methods Among 20 experimental volunteers from the team of martial arts athletes, five men and five women in the experimental group and five men and five women in the control group, the experiment was conducted by strengthening the training of the abdominal center in a specific protocol for four months. Results Among the control group athletes in orthostatic posture, eyes open on both feet before the experiment, the flexibility score increased by 6.69% after the experiment; among the control group athletes in the same orthostatic posture, with eyes closed, the flexibility score increased by 3.41% after the experiment. Conclusion Strength training with the developed protocol and traditional strength training can promote flexibility improvement in martial arts athletes, with the specific protocol presenting the most significant effects. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
RESUMO Introdução A boa flexibilidade é uma das bases para o desenvolvimento do alto nível em exercícios. O treinamento de flexibilidade nas artes marciais concentra-se principalmente no treinamento de flexibilidade do centro abdominal, membros superiores e inferiores. Objetivo Explorar o efeito do fortalecimento do centro abdominal sobre a flexibilidade nos atletas de artes marciais. Métodos Entre os 20 voluntários experimentais da equipe de atletas de artes marciais, sendo 5 homens e 5 mulheres no grupo experimental, e 5 homens e 5 mulheres no grupo de controle, o experimento conduziu-se por treinamento de fortalecimento do centro abdominal num protocolo específico por quatro meses. Resultados Entre os atletas do grupo de controle em postura ortostática, olhos abertos sobre ambos os pés, antes da realização do experimento, a capacidade de flexibilidade aumentou em 6,69% após o término do experimento; entre os atletas do grupo de controle encontravam-se na mesma postura ortostática, de olhos fechados, a pontuação de flexibilidade aumentou em 3,41% após o experimento. Conclusão O treinamento de força com o protocolo desenvolvido e o treinamento de força tradicional podem promover a melhoria da flexibilidade dos atletas de artes marciais, sendo o protocolo específico o que apresenta maiores efeitos significativos. Nível de evidência II; Estudos terapêuticos - investigação dos resultados do tratamento.

Métodos Entre 20 voluntarios experimentales de un equipo de atletas de artes marciales, siendo 5 hombres y 5 mujeres en el grupo experimental, y 5 hombres y 5 mujeres en el grupo de control, se llevó a cabo el experimento mediante un entrenamiento de fortalecimiento del núcleo abdominal en un protocolo específico durante cuatro meses. Resultados Entre los atletas del grupo de control en postura ortostática, con los ojos abiertos sobre ambos pies, antes del experimento, la capacidad de flexibilidad aumentó en un 6,69% tras el final del experimento; entre los atletas del grupo de control en la misma postura ortostática, con los ojos cerrados, la puntuación de flexibilidad aumentó en un 3,41% tras el experimento. Conclusión El entrenamiento de fuerza con el protocolo desarrollado y el entrenamiento de fuerza tradicional pueden promover la mejora de la flexibilidad en atletas de artes marciales, siendo el protocolo específico el que presenta efectos más significativos.

ABSTRACT
@#Abstract: Objective To collect the cases of laboratory-acquired infections (LAI) reported in literatures in China, summarize the infection routes and causes of LAI in China, in order to improve laboratory staff's understanding of its occupational health and safety risks. Methods The cases of laboratory-acquired infection reported in domestic literatures were collected from PubMed, CNKI, Wanfang Database, CBM China Biomedical Literature Database up to April 11, 2022, retrospectively analyze the number and causes of LAI reports, the main risk factors of LAI and its harm to society, the consequences of LAI or the leakage of pathogenic microorganisms, and put forward the relevant countermeasures of biological safety. Results A total of 22 LAI reports were collected, reviewed and integrated into 21 reports. There were 7 kinds of pathogenic microorganisms. The main pathogenic microorganisms were hantavirus (42.86%, n=9) and Brucella (33.33%, n=7). There were 122 cases and 3 deaths in the laboratory. Most of the reports came from research laboratories (66.67%, n=14). The main route of infection was inhalation of aerosol (42.86%, n=9), followed by transdermal route (38.09%, n=8). Conclusions Failure to report LAI events will increase the risk of pathogenic microorganisms spreading to people outside the laboratory and the environment through infected laboratory staff. Local health institutions and laboratories should be encouraged to report LAI cases as a powerful tool for monitoring accidental leakage of pathogenic microorganisms and further improving laboratory biosafety. The laboratory needs strong biosafety measures to protect staff's health and prevent environmental pollution caused by accidental leakage of pathogenic microorganisms.
