RESUMO
ABSTRACT Objective: This paper explores whether the use of aquatic relaxation methods can effectively eliminate fatigue after high-intensity load training. Methods: Twenty athletes were invited to participate in the experimental aquatic relaxation-based test after a battery of strenuous exercise. The following markers were analyzed: blood urea, blood testosterone, hemoglobin, and cortisol. The data were collected before training, 30 minutes after the exercises, and the next day. Results: Sensible changes in the markers were observed. The fatigue manifested by sports training is closely related to several factors, such as sports training load, cardiac function, oxygen consumption, and metabolite accumulation. Conclusions: Aquatic relaxation can effectively relieve fatigue in athletes. Although there is a positive effect, traditional means should not be substituted. It is suggested that the coach combine relaxation methods according to each athlete's preference. Level of evidence II; Therapeutic studies - investigation of treatment results.
RESUMO Objetivo: Este artigo explora se o uso de métodos de relaxamento aquático pode efetivamente eliminar a fadiga após o treinamento com carga de alta intensidade. Métodos: Vinte atletas foram convidados a participar do teste experimental baseado em relaxamento aquático após uma bateria de exercícios extenuantes. Os seguintes marcadores foram analisados: ureia sanguínea; testosterona no sangue, hemoglobina e cortisol. A coleta foi feita antes do treinamento, 30 minutos após os exercícios e no dia seguinte. Resultados: Foram observadas sensíveis alterações nos marcadores. A fadiga manifestada pelo treinamento esportivo está intimamente relacionada a vários fatores, como carga de treinamento esportivo, função cardíaca, consumo de oxigênio e acúmulo de metabólitos. Conclusões: O relaxamento aquático pode efetivamente aliviar a fadiga dos atletas. Embora exista um efeito positivo, os meios tradicionais não devem ser substituídos. Sugere-se que o treinador combine os métodos de relaxamento de acordo com a preferência de cada atleta. Nível de evidência II; Estudos terapêuticos - investigação de resultados de tratamento.

Métodos: Se invitó a veinte atletas a participar en la prueba experimental basada en la relajación acuática después de una batería de ejercicios extenuantes. Se analizaron los siguientes marcadores: urea en sangre; testosterona en sangre, hemoglobina y cortisol. La colecta se realizó antes del entrenamiento, 30 minutos después de los ejercicios y al día siguiente. Resultados: Se observaron alteraciones sensibles en los marcadores. La fatiga manifestada por el entrenamiento deportivo está estrechamente relacionada con varios factores, como la carga de entrenamiento deportivo, la función cardíaca, el consumo de oxígeno y la acumulación de metabolitos. Conclusiones: La relajación acuática puede aliviar eficazmente la fatiga en los deportistas. Aunque el efecto es positivo, los medios tradicionales no deben ser sustituidos. Se sugiere que el entrenador combine los métodos de relajación según la preferencia de cada atleta. Nivel de evidencia II; Estudios terapéuticos - investigación de resultados de tratamiento.
RESUMO
INTRODUCTION: Chronic hepatitis B (CHB) is still a public health problem and its mechanism remains unclear. In this study, we detect the skewness of T cell receptor beta chain variable gene (TCR Vß) in peripheral blood lymphocytes (PBL) and the liver infiltrating lymphocytes (LIL) of patients with CHB; and hope to provide information for further research on the pathogenic mechanism of CHB. MATERIAL AND METHODS: Fifteen patients with CHB, ten healthy volunteers and three patients with liver cysts were recruited as the subjects. The usage of TCR Vß of PBL and LIL were measured and compared; the associations of the TCR Vß usage of PBL with some hematological indices, including human leukocyte antigen (HLA) alleles, percents of CD4+ and CD8+ T cells, sera levels of HBV-DNA and IFN-γ, were analyzed. RESULTS: In PBL, Vß12 and Vß13.1 were the highest predominant usage genes which usage frequencies were all 46.7%; Vß23 was the key limited usage gene (40.0%). In LIL, the mainly predominant and limited usage gene was Vß13.1 (73.3%) and Vß23 (46.7%), respectively. About half of the patients with CHB with HLA-DR9 or HLA-DR12 showed the predominant usage of Vß5.2 or Vß13.2. In patients with CHB, the percentage of CD4+ T cells was 33.41 ± 5.39 %, that of CD8+ T cells was 28.67 ± 6.77 %; the concentration of IFN-γ was 182.52 ± 44.16 pg/mL. Compared to the healthy controls, there were significant differences for these data (P < 0.05). Neither ALT nor HBV-DNA was relative to the usage of TCR Vß. CONCLUSIONS: PBL and LIL share the common sknewness of TCR Vß genes, which probably relates to some hematological indices. However, the roles of such similarities and associations in the development of CHB need further study.
