Analysis of different injuries of basketball players based on surface electromyography / Análise de diferentes lesões em jogadores de basquete com base na eletromiografia de superfície / Análisis de diferentes lesiones de jugadores de baloncesto basado en electromiografía superficial

ABSTRACT Assessing the performance of basketball players is very important in the implementation of technical training programs. The application of electromyography (EMG) in basketball players is still relatively small. The evaluation of athletes' muscle state index by EMG can guide sports training. This study used surface electromyography to test and compare EMG data, analyze muscle discharge timing, contribution rate and integral EMG value of the turning movement, aiming to explore the prevention mechanism of different types of injury affecting basketball players. The synchronous measurement model of EMG signal and plantar pressure curve in jump shot process of basketball players is established to deepen coaches' understanding of jump shot movement rules and guide athletes to conduct scientific jump shot training. The research shows that the incidence of knee joint injury is relatively high in basketball players. Patella strain and softening, knee meniscus injury and cruciate ligament injury are the main types of injury, and there is no difference between genders.

RESUMO A avaliação do desempenho dos jogadores de basquete é muito importante na implementação de programas de treinamento técnico. A aplicação de eletromiografia (EMG) no basquetebol ainda é relativamente pequena. A avaliação do índice de estado muscular dos atletas por EMG pode guiar o treinamento esportivo. Este estudo utilizou a eletromiografia de superfície para testar e comparar os dados da EMG, analisar o tempo de descarga muscular, a taxa de contribuição e o valor integral da EMG do movimento de rotação, com o objetivo de explorar o mecanismo de prevenção de diferentes tipos de lesões entre jogadores de basquete. O modelo de medição síncrona do sinal EMG e da curva da pressão plantar no processo de arremessos por parte de jogadores de basquete é estabelecido para aprofundar a compreensão dos treinadores sobre as regras de arremessos e guiar atletas a realizar treinamentos de arremessos com bases científicas. A pesquisa mostra que a incidência de lesão nas articulações do joelho é relativamente alta entre os jogadores de basquete. Luxação e amolecimento de patela, lesão de menisco e lesão do ligamento cruzado são os principais tipos de lesão, e não há diferença entre generosos sexos masculino e feminino.

RESUMEN La evaluación del desempeño de los jugadores de baloncesto es muy importante en la implementación de programas de entrenamiento técnico. La aplicación de electromiografía (EMG) en el baloncesto aun es relativamente pequeña. La evaluación del índice de estado muscular de los atletas por EMG puede guiar el entrenamiento deportivo. Este estudio utilizó la electromiografía de superficie para testear y comparar los datos de la EMG, analizar el tiempo de descarga muscular, la tasa de contribución y el valor integral de la EMG del movimiento de rotación, con el objetivo de explorar el mecanismo de prevención de diferentes tipos de lesiones entre jugadores de baloncesto. El modelo de medición síncrona de la señal EMG y de la curva de la presión plantar en el proceso de lanzamientos por parte de jugadores de baloncesto es establecido para profundizar la comprensión de los entrenadores sobre las reglas de lanzamientos y guiar a los atletas a realizar entrenamientos de lanzamientos con bases científicas. La investigación muestra que la incidencia de lesión en las articulaciones de la rodilla es relativamente alta entre los jugadores de baloncesto. Luxación y ablandamiento de rótula, lesión de menisco y lesión del ligamento cruzado son los principales tipos de lesión, y no hay diferencia entre los sexos.

Docetaxel injection and Capecitabine tablets combined with Oxaliplatin injection in postoperative chemotherapy for esophageal cancer / 中国胸心血管外科临床杂志

@#Objective    To investigate the efficacy of Docetaxel injection and Capecitabine tablets combined with Oxaliplatin injection in chemotherapy for patients after esophageal cancer surgery. Methods    We retrospectively analyzed the clinical data of 101 patients with esophageal cancer who underwent radical surgery from June 2010 to December 2012, including 58 males and 43 females. According to the different treatment methods they were divided into a study group (58 patients, 32 males and 26 females, postoperatively receiving Docetaxel injection, Capecitabine tablets, Oxaliplatin injection and chemotherapy) and a control group (43 patients, 26 males and 17 females, taking Docetaxel injection and Capecitabine tablets for 4 consecutive courses). We compared the difference in the outcomes between the two groups. Results    There was no significant difference in the level of serum anticancer antigen (CEA), carbohydrate antigen 125 (CA125), carbohydrate antigen 199 (CA199) and squamous cell carcinoma antigen (SCC) before chemotherapy between two groups (P>0.05). After chemotherapy, the level of serum CEA, CA125, CA199, SCC in the study group was significantly lower than that in the control group (P<0.05). The 1-year survival rate of the study group was 92.59% and the 2-year survival rate was 70.37%, which were not significantly different from those of the control group  (P>0.05). The 3-year survival rate of the study group was significantly higher than that of the control group (57.41 % vs. 32.43%, P<0.05). The mean survival time of the study group was longer than that of the control group (31 months vs. 22 months, P=0.001). Conclusion    Docetaxel injection and Capecitabine tablets combined with Oxaliplatin injection for the treatment of esophageal cancer surgery can significantly reduce levels of tumor markers in serum after esophageal cancer surgery, and is favorable for the long-term survival of patients, but adverse reactions should be noted.
