Effects of acupoint application therapy with Chinese medicine combined with tiotropium bromide inhalation on quality of life in patients with stable chronic obstructive pulmonary disease / 中国基层医药

Objective:To investigate the effects of acupoint application therapy with Chinese medicine combined with tiotropium bromide inhalation on quality of life in patients with stable chronic obstructive pulmonary disease (COPD).Methods:A total of 109 patients with stable COPD admitted to People's Hospital of Gaomi from March 2019 to May 2020 were included in this study. They were randomly divided into a control group ( n = 54) and an observation group ( n = 55). Both groups were given tiotropium bromide powder inhalation and acupoint application therapy ( Dazhui, Shenque, Feishu, Pishu, Shenshu and Zusanli). Chinese medicine ointment was applied in the observation group, but not in the control group. All patients were treated for 6 consecutive months. Before and after treatment, pulmonary function indicators [forced expiratory volume in the first second (FEV 1), the percentage of expiratory volume in the first second (FEV 1%), forced vital capacity (FVC), FEV 1/FVC], modified Medical Research Council (mMRC) dyspnea scale score, and the Saint George's Respiratory Questionnaire (SGRQ) score were compared between the two groups before and after treatment to evaluate therapeutic efficacy and quality of life. Results:Before and after treatment, there were no significant differences in FEV 1, FEV 1% and FEV 1/FVC between the two groups (all P > 0.05). After treatment, mMRC score and SGRQ total score in the observation group were (1.91 ± 0.27) points and (38.54 ± 8.18) points, respectively, which were significantly lower than (2.43 ± 0.33) points and (43.12 ± 7.86) points in the control group ( t = 4.93, 4.47, both P < 0.05). The number of exacerbations and the number of hospitalizations were (0.42 ± 0.09) times/6 months and (0.27 ± 0.05) times/6 months in the observation group and they were (0.69 ± 0.17) times/6 months and (0.47 ± 0.13) times/6 months in the control group. There were significant differences in these indices between the two groups ( t = 3.90, 3.85, P < 0.05). Conclusion:Acupoint application therapy with Chinese medicine combined with tiotropium bromide inhalation has a good therapeutic effect on stable COPD. The combined therapy can reduce the number of acute attacks and improve patient's quality of life. This study is scientific and innovative.

Role of Mitophagy in Myocardial Ischemia/Reperfusion Injury and Chinese Medicine Treatment / 中国结合医学杂志

Mitophagy is one of the important targets for the prevention and treatment of myocardial ischemia/reperfusion injury (MIRI). Moderate mitophagy can remove damaged mitochondria, inhibit excessive reactive oxygen species accumulation, and protect mitochondria from damage. However, excessive enhancement of mitophagy greatly reduces adenosine triphosphate production and energy supply for cell survival, and aggravates cell death. How dysfunctional mitochondria are selectively recognized and engulfed is related to the interaction of adaptors on the mitochondrial membrane, which mainly include phosphatase and tensin homolog deleted on chromosome ten (PTEN)-induced kinase 1/Parkin, hypoxia-inducible factor-1 α/Bcl-2 and adenovirus e1b19k Da interacting protein 3, FUN-14 domain containing protein 1 receptor-mediated mitophagy pathway and so on. In this review, the authors briefly summarize the main pathways currently studied on mitophagy and the relationship between mitophagy and MIRI, and incorporate and analyze research data on prevention and treatment of MIRI with Chinese medicine, thereby provide relevant theoretical basis and treatment ideas for clinical prevention of MIRI.

Aportes navales al inicio de la investigación en medicina tropical en el siglo XIX / Naval contributions at the beginning of the tropical medicine research in the 19th century

Resumen En la segunda mitad del siglo XIX, el inicio de la investigación en medicina tropical se vio favorecido con aportes de empresas navieras, como la Compañía Holandesa de las Indias Orientales, siendo quizás el más importante su gestión apoyando la creación en China del Servicio Marítimo Imperial de Aduanas (1854-1950), impuesto al débil gobierno chino por los cónsules de Inglaterra, Francia y EEUU, para establecer tasas regulares en todos sus puertos, que pronto amplió sus funciones a la información de mareas, tifones y clima, terminando por crear en 1863 un Servicio Médico para detectar epidemias y establecer cuarentenas. Este Servicio Médico editó una revista, Medical Reports, en la cual publicaron distinguidos investigadores, como Patrick Manson, Padre de la Medicina Tropical. Comentamos algunos informes aparecidos en ella, para conocer su real importancia en el desarrollo de la medicina tropical.

Abstract In the second half of the 19th century, the beginning of the research on tropical medicine was favored with contributions from shipping companies, like Dutch East India Company, being perhaps the most important of these its collaboration in the creation of the China Imperial Maritime Customs Service (1854-1950), imposed by consuls from England, France and USA, on the weak Chinese government in order to establish regular taxes in all its ports, soon expanding its functions with reports on tides, typhoons and weather, ending up creating a medical service in 1863 to detect epidemics and establish quarantines. This medical service published a Journal, the Imperial Maritime Customs Medical Reports, where they wrote distinguished investigators, such as Patrick Manson, Father of Tropical Medicine. We comment in some reports of this journal, to get an idea about its real importance in the development of tropical medicine.

Evaluation of Expression and Prognostic Significance of FUNDC1 Protein in Non-small Cell Lung Cancer Based on TCGA Database and Clinicopathology / 肿瘤防治研究

Objective To evaluate the expression of FUNDC1 and its clinical significance in non-small cell lung cancer. Methods We used TCGA database to analyze the difference of mitochondrial receptors (DRP1, BNIP3, FUNDC1, NIX, RHEB, LC3, OPA1 and MFN1) expression between normal and NSCLC tissues, as well as its effect on the prognosis of NSCLC patients. Immunohistochemistry was used to detect FUNDC1 expression. The correlations between FUNDC1 expression and clinicopathological characteristics, prognosis were evaluated by SPSS 22.0 statistical software. Results FUNDC1 expression was increased in NSCLC tissues, compared with normal tissues. FUNDC1 expression was related to the degree of differentiation and lymph node metastasis, but not to gender, age, pathological type, distant metastasis or TNM classification. The Cox regression analysis showed that FUNDC1 protein expression, lymph node metastasis, differentiation degree were independent prognostic factors of NSCLC. Increased FUNDC1 expression was related to decreased OS and PFS (P < 0.01). Conclusion The up-regulation of FUNDC1 expression can affect the prognosis of patients with NSCLC. It may be a new potential target for treating with NSCLC.

Effects of intravenous combined epidural anesthesia on perioperative hemodynamic indexes, cardiac function and immune function during laparoscopic surgery in elderly gastric cancer patients complicated with coronary heart disease / 肿瘤研究与临床

Objective:To explore the effects of intravenous combined epidural anesthesia on perioperative hemodynamic indexes, cardiac function and immune function during laparoscopic surgery in elderly gastric cancer patients complicated with coronary heart disease.Methods:A total of 94 elderly gastric cancer patients with coronary heart disease who were admitted to Shanxi Province Cancer Hospital from January 2017 to June 2021 were selected. They were divided into the total intravenous anesthesia group (control group) and intravenous combined epidural anesthesia group (observation group) by random envelope lottery, with 47 cases in each group. Hemodynamic indexes, cardiac function, immune function, pain and sedation scores were compared between the two groups.Results:When pneumoperitoneum was established (T 1) and the left gastric artery was immediately free during operation (T 2), systolic blood pressure in the observation group was (136.6±9.9) mmHg (1 mmHg = 0.133 kPa) and (133.9±9.4) mmHg, and diastolic blood pressure was (74.6±4.6) mmHg and (80.7±6.0) mmHg; heart rate was (79.8±4.0) times/min and (80.9±2.7) times/min, respectively. The systolic blood pressure of the control group was (159.3±7.6) mmHg and (162.5±8.5) mmHg, and the diastolic blood pressure was (91.2±5.2) mmHg and (88.3±4.7) mmHg, respectively. The heart rate was (106.2±3.3) times/min and (101.9±4.0) times/min, respectively; compared with the control group at the same time point, the observation group had lower blood pressure and slower heart rate ( t values were 4.25, 2.53, 6.40, 6.81, 1.85, and 1.35, all P < 0.05). The blood concentrations of cardiac troponin and creatine kinase isoenzyme in the control group were (0.143±0.052) ng/ml and (5.65±0.77) mg/L at 12 h (T 4) after surgery, which were higher than those in the observation group [(0.098±0.015) ng/ml and (3.08±1.06) mg/L] ( t values were 4.32 and 10.19, both P < 0.05). The intraoperative utilization rate of vasoactive drugs and the incidence of electrocardiogram abnormalities in the observation group were 19.1% (9/47) and 25.5% (12/47), which were lower than those in the control group [48.9% (23/47) and 55.3% (26/47)] ( χ2 values were 8.49 and 8.66, both P < 0.05). Compared with 1 day before operation (T 5), the proportion of CD4 + T cells increased and the proportion of CD8 + T cells decreased in control group at 3 days after operation (T 6) (both P < 0.05). The pain score and sedation score of the observation group at 12 h (T 4) and 1 day after surgery (T 7) were better than those of the control group (all P < 0.05). Conclusions:Laparoscopic radical gastrectomy with intravenous combined epidural anesthesia in elderly gastric cancer patients with coronary heart disease can achieve better anesthesia effect, and can provide better protection for the patient's cardiac function and immune function.

Nos bailes Arrabaldinos: experiências e tensões entre clubes dançantes de Bangu (1899-1922) / In Arrabaldine dances: experiences and tensions between dance clubs in Bangu (1899-1922)

Nas primeiras décadas do século XX, as sociedades dançantes Flor da União e Flor da Lyra tornaram-se referências no que tangue aos divertimentos em Bangu e nos demais bairros suburbanos da cidade do Rio de Janeiro. Tendo em conta que foram expressões de movimentos de formações identitárias e de busca de valorização local, este estudo tem por objetivo discutir as experiências dessas agremiações dançantes, tanto na lógica que explica a organização, quanto aos desafios e tensões que seus membros enfrentaram para consolidá-las. Quanto ao recorte em tela (1899-1922), levou-se em consideração a fundação da sociedade Flor da União, em 1899, e, 1922, período em que os movimentos irradiados ao redor das atividades dos clubes tornaram-se cada vez mais ocasionais. Dessa forma, esperamos elucidar um trajeto distinto sobre a história do bairro, dos subúrbios e do Rio de Janeiro, na tentativa de compreender como atores diversos foram centrais na formação do espaço, ou seja, atuaram na constituição de uma identidade local.

In the first decades of the 20th century, the dance societies Flor da União and Flor da Lyra became references in terms of entertainment in Bangu and in the other suburban neighborhoods of the city of Rio de Janeiro. Bearing in mind that they were expressions of movements of identity formations and the search for local valorization, this study aims to discuss the experiences of these dancing associations, both in the logic that explains the organization, as well as the challenges and tensions that its members faced to consolidate themselves. them. As for the cutout on canvas (1899- 1922), the foundation of the Flor da União society in 1899 was taken into account, and in 1922, a period in which the irradiated movements around the club's activities became increasingly occasional. In this way, we hope to elucidate a different path about the history of the neighborhood, the suburbs and Rio de Janeiro, in an attempt to understand how diverse actors were central in the formation of space, that is, they acted in the constitution of a local identity.

Post-laser in situ keratomileusis interface Arthrographis kalrae keratitis / Interface de pós-laser ceratomileuse in situ Arthographis Kalrae ceratite

ABSTRACT We describe a case of keratomycosis caused by Arthographis kalrae after excimer laser keratomileusis. A 38-year-old female developed stromal keratitis eight weeks after refractive surgery. She developed severe corneal stromal infiltration and mild anterior segment inflammation, which could not be treated with topical voriconazole 1%, but topical natamycin 5% ameliorated her condition. A reactivation of keratomycosis symptoms was observed; therefore, longer treatment was administered to the patient. It has been reported that A. kalrae keratomycosis is associated with exposure to soil and contact lens usage. However, the patient, who lived in a rural location, was neither involved in gardening activities nor had a history of wearing contact lenses. This is the first case of post-refractive A. kalrae keratomycosis.

RESUMO Descrevemos um caso de ceratomicose por Arthographis kalrae após ceratomileusis por excimer laser. Uma mulher de 38 anos desenvolveu ceratite estromal oito semanas após a cirurgia refrativa. Ela desenvolveu infiltração estromal grave da córnea e uma leve inflamação do segmento anterior, que não pode ser tratada com voriconazol tópico a 1%, mas a natamicina tópica a 5% melhorou sua condição. Uma reativação dos síntomas de ceratomicose foi observada; portanto, tratamento mais prolongado foi administrado a paciente. Tem sido relatado que a ceratomicose por A. kalrae está associada à exposição ao solo e ao uso de lentes de contato. No entanto, a paciente, que vivía em um local rural, não estava envolvida em atividades de jardinagem e nem tinha histórico de uso de lentes de contato. Este é o primeiro caso de ceratomicose pós-refrativa por A. kalrae.

Capacidad predictiva del apoyo a la autonomía en clases de educación física sobre el ejercicio físico / Predictive ability to support autonomy in classes of physical education on physical exercise

Resumen El objetivo de este estudio consistió en comprobar la capacidad de predicción del apoyo a la autonomía del docente en educación física, las necesidades psicológicas básicas y la motivación autodeterminada sobre la diversión, la importancia e intención hacia la educación física y la actividad física habitual. Se empleó una muestra de 718 estudiantes (346 chicos y 372 chicas) con edades comprendidas entre los 13 y los 19 años (M = 15,76, DT = 1,20). Se midió el apoyo a la autonomía, las necesidades psicológicas básicas, la motivación, la diversión, la importancia de la educación física, la intencionalidad para ser físicamente activo y la actividad física habitual. Se realizaron análisis estadísticos descriptivos y las correlaciones bivariadas de todas las variables objeto de estudio, análisis factoriales confirmatorios de los instrumentos y un análisis mediante el modelo de regresión estructural. Los resultados revelaron relaciones positivas y significativas entre todas las variables. Así, el apoyo a la autonomía predijo positivamente la satisfacción de las necesidades psicológicas básicas, y esta, a su vez, predijo la motivación autodeterminada, que predijo la diversión. La diversión predijo la importancia concedida a la educación física, y esta la intención de ser físicamente activo, que finalmente predijo la tasa de actividad física habitual. Los resultados contribuyen a optimizar el compromiso de los jóvenes hacia la actividad física, tanto dentro como fuera del aula.

Abstract The objective of this study was to check the prediction capacity of teacher's autonomy support in physical education, basic psychological needs and motivation self-determined about fun, importance and intention towards physical education and the usual physical activity. Participated a sample of 718 students (346 boys and 372 girls) with ages between 13 and 19 years (M = 15.76, SD = 1.20). Autonomy support perceived, basic psychological needs, motivation, fun, the importance of Physical education, intentionality to be physically active and habitual physical activity was measured. A descriptive statistical analyzes and bivariate correlations of all the variables object of study, confirmatory factor analyzes of the instruments and an analysis through the structural regression model was performed. The results revealed a positive and significant relationship between all the variables. Thus, the autonomy support positively predicted the satisfaction of the basic psychological needs, and this, in turn, predicted self-determined motivation, which predicted fun the fun, that predicted the importance given to physical education, and it the intention to be physically active, which finally predicted the usual physical activity rate. The results help to optimize the commitment of young people to physical activity, both inside and outside the classroom.

Structural insights into the recognition of phosphorylated FUNDC1 by LC3B in mitophagy

Mitophagy is an essential intracellular process that eliminates dysfunctional mitochondria and maintains cellular homeostasis. Mitophagy is regulated by the post-translational modification of mitophagy receptors. Fun14 domain-containing protein 1 (FUNDC1) was reported to be a new receptor for hypoxia-induced mitophagy in mammalian cells and interact with microtubule-associated protein light chain 3 beta (LC3B) through its LC3 interaction region (LIR). Moreover, the phosphorylation modification of FUNDC1 affects its binding affinity for LC3B and regulates selective mitophagy. However, the structural basis of this regulation mechanism remains unclear. Here, we present the crystal structure of LC3B in complex with a FUNDC1 LIR peptide phosphorylated at Ser17 (pS), demonstrating the key residues of LC3B for the specific recognition of the phosphorylated or dephosphorylated FUNDC1. Intriguingly, the side chain of LC3B Lys49 shifts remarkably and forms a hydrogen bond and electrostatic interaction with the phosphate group of FUNDC1 pS. Alternatively, phosphorylated Tyr18 (pY) and Ser13 (pS) in FUNDC1 significantly obstruct their interaction with the hydrophobic pocket and Arg10 of LC3B, respectively. Structural observations are further validated by mutation and isothermal titration calorimetry (ITC) assays. Therefore, our structural and biochemical results reveal a working model for the specific recognition of FUNDC1 by LC3B and imply that the reversible phosphorylation modification of mitophagy receptors may be a switch for selective mitophagy.

Modelo de predicción de la satisfacción y diversión en Educación Física a partir de la autonomía y el clima motivacional / Prediction Model of Satisfaction and Enjoyment in Physical Education from the Autonomy and Motivational Climate

El objetivo de este trabajo fue hallar un modelo de predicción de la satisfacción y diversión hacia la Educación Física partiendo del clima de aprendizaje y teniendo en cuenta el apoyo a la autonomía del profesorado y la propia percepción de autonomía del alumnado. Se utilizó una muestra de 758 alumnos de secundaria con edades entre 13 y 18 años. Se aplicó a los participantes de la investigación, la versión española adaptada a la educación física, de los siguientes instrumentos: Learning and Performance Orientations in Physical Education Classes Questionnaire, Learning Climate Questionnaire, Sport Satisfaction Instrument y el factor autonomía del Basic Psychological Needs in Exercise Scale. Los resultados señalaron que el clima motivacional implicado en el aprendizaje predecía positivamente el apoyo a la autonomía por parte del profesor y esta predecía la propia percepción de autonomía del alumno. Asimismo, la percepción de autonomía predijo positivamente la satisfacción/diversión y negativamente el aburrimiento en las clases. Como conclusión, los docentes deben favorecer un clima de aprendizaje que apoye la autonomía y favorezca la percepción de esta en el alumno para conseguir que se diviertan en las clases de Educación Física.

The aim of this work was to find a model to predict satisfaction and fun to the physical education based on learning climate and considering supporting to the autonomy of teachers and the perception of autonomy of students. A sample of 758 secondary school students aged between 13 and 18 was used. The following instruments were used: the Spanish version adapted to Physical Education of Learning and Performance Orientations in Physical Education Classes Questionnaire, Learning Climate Questionnaire, Sport Satisfaction Instrument and autonomy factor in Basic Psychological Needs in Exercise Scale. The results showed that learning motivational climate positively predicted perceived autonomy support on the teacher part and this predicted the self perception of autonomy on the part of students. In the same way, the perceived autonomy positively predicted satisfaction/fun and negatively boredom in class. In conclusion, teachers should foster a learning climate that supports and promotes the autonomy perceived autonomy in students for them to have fun in physical education classes.

Educação Física na educação infantil: produção de saberes no cotidiano escolar / Physical Education on chilhood education early stages: knowledge production on everyday school life / La Educación Física en educación infantil: la producción de conocimiento en el cotidiano escolar

Analisa os desafios e as possibilidades da intervenção pedagógica de dois professores de Educação Física na etapa inicial da Educação Infantil (seis meses a três anos) em dois Centros Municipais de Educação de Vitória (CMEIs). Adota os Estudos com o Cotidiano como pressuposto teórico-metodológico e utiliza como fontes as narrativas dos professores e das estagiárias,2 que foram sistematizadas em portfólios. A análise dos dados indica que os desafios da intervenção estão relacionados com as especificidades do comportamento infantil e com as rotinas estabelecidas nos CMEIs. Quanto às possibilidades de ensino, sobressaem práticas pedagógicas que concebem a criança como "sujeito de direitos" e a centralidade da brincadeira e do jogo na prática pedagógica da Educação Física na Educação Infantil.

This study analyzed the challenges and possibilities of the intervention of two Physical Education teachers in the early stages of childhood education (six months to three years old) in two "Centros Municipais de Educação de Vitória" (CMEIs). It adopts the study of everyday life as theoretical and methodological assumption and uses as source the professors/trainees narratives, which were systematized on portfolios. The sources indicate that the challenges for the intervention are related with childhood behavior specificities, which were revealed on the process of pedagogic intervention, as well as the applied routines on CMEIs. As to the possibilities, there emerged pedagogical practices which conceive the child as a "subject of rights", and the game centrality as methodological strategy.

Aprueba los Estudios con el Cotidiano como presupuesto teórico-metodológico y utiliza como fuentes los relatos de los profesores y de las alumnas pasantes, que han sido sistematizados en portfólios. Análisis de los datos indican que los desafíos para la intervención están relacionados con los aspectos específicos del comportamiento infantil y con las rutinas establecidas en CMEIs. Con respecto a las posibilidades de la enseñanza, se destacan las prácticas pedagógicas que conciben a los niños como "sujeto de derechos" y la centralidad del juego como estrategia metodológica.

Estudio psicométrico y predicción de la importancia de la educación física a partir de las orientaciones de meta ("Perception of Success Questionnaire - POSQ") / Psychometric study and the prediction of the importance of physical education from goal guidance ("Perception of Success Questionnaire - POSQ")

El objetivo de esta investigación fue doble: (a) analizar las propiedades psicométricas del Perception of Success Questionnaire (POSQ) adaptado a la Educación Física (EF); y (b) analizar la predicción de la importancia y utilidad concedida a la EF a partir de las orientaciones de meta, percepción de competencia y satisfacción del alumnado. El cuestionario estuvo compuesto por los siguientes instrumentos: POSQ, Escala de Necesidades Psicológicas Básicas en el Ejercicio, Satisfacción con la EF e Importancia de la EF. Se administró a 846 estudiantes españoles de secundaria de 12 a 19 años. La estructura del POSQ se analizó mediante procedimientos confirmatorios y mostró una consistencia interna fiable y una estructura factorial estable (apoyando el modelo teórico hipotetizado: orientación al ego y a la tarea). Así, se considera un instrumento válido para medir la orientación de meta disposicional en EF. Para la predicción de la importancia de la EF a partir de las orientaciones de meta, competencia y satisfacción, se halló un modelo de ecuaciones estructurales que confirmó que la orientación a la tarea es la que más influye en la percepción de competencia y ésta en la satisfacción/diversión, lo que predice que el alumnado considere más importante y útil la asignatura. (AU)

The present research has two main goals: (a) to analyze psychometric properties of the Perception of Success Questionnaire (POSQ) adapted to Physical Education (PE), and (b) to analyze the prediction of importance and usefulness granted to PE from goal orientations, perceived competence and student satisfaction. The questionnaire consisted of the following instruments: POSQ, Basic Psychological Needs in Exercise Scale, Satisfaction with PE and the Importance of PE. They were administered to 846 Spanish high school students aged 12 to 19 years. POSQ structure was analyzed by confirmatory procedures and it showed reliable internal consistency and a stable factor structure which supports the hypothesized theoretical model: ego and task orientation. Thus, it is considered a valid instrument to measure dispositional goal orientation in PE. For predicting the importance of PE from goal orientations, competence and satisfaction, it was used a structural equation model which confirmed that task orientation is the most influential on perceived competence, and the latter in satisfaction/fun. Fact that predicts the students consider the subject more important and useful. (AU)

Evaluation of antifungal activity of essential oils against potentially mycotoxigenic Aspergillus flavus and Aspergillus parasiticus

The antifungal activity of essential oils of fennel (Foeniculum vulgare Mill., Apiaceae), ginger (Zingiber officinale Roscoe, Zingiberaceae), mint (Mentha piperita L., Lamiaceae) and thyme (Thymus vulgaris L., Lamiaceae) was evaluated against mycotoxin producers Aspergillus flavus and A. parasiticus. High Resolution Gas Chromatography was applied to analyze chemical constituents of essential oils. The effect of different concentrations of essential oils was determined by solid medium diffusion assay. Mycelial growth and sporulation were determined for each essential oil at the concentrations established by solid medium diffusion assay. At the fifth, seventh and ninth days the mycelial diameter (Ø mm) and spore production were also determined. FUN-1 staining was performed to assess cell viability after broth macrodilution assay. Trans-anethole, zingiberene, menthol and thymol are the major component of essential oils of fennel, ginger, mint and thyme, respectively. The effective concentrations for fennel, ginger, mint and thyme were 50, 80, 50 and 50% (oil/DMSO; v/v), respectively. The four essential oils analysed in this study showed antifungal effect. Additionally, FUN-1 staining showed to be a suitable method to evaluate cell viability of potential mycotoxigenic fungi A. flavus and A. parasiticus after treatment with essential oils.

Effects of a single session of physical exercise on body state image / Efectos de una sección de ejercicios físicos en la imagen corporal / Efeitos de uma sessão de exercícios físicos na imagem corporal

Despite the fact that athletes and physically active persons are generally more satisfied with their bodies than sedentary people, physical activity seems to exert both negative and positive influences on body image. The aim of this study was to investigate the effect of a single session of exercise in state body image modification. In particular, we observed if a single session of sport or fitness activity could have a positive influence on state body image, considered as an episodic, evaluative and affective perception of the own physical appearance. Results showed an increase of the mean state body image rate (assessed with the Body Image States Scales, BISS) after a one-hour session of sport or fitness activities in a sample of 295 individuals. Intensity and fun seemed to be key-factors in state body image enhancement. These findings could have significant implications in the treatment of BI disturbances and in their prevention.

Aunque atletas y personas físicamente activas estén generalmente más satisfechos con sus cuerpos, cuando comparados a individuos sedentarios, la actividad física parece ser responsable por influenciar de manera positiva así como negativa el imagen corporal. El objetivo del estudio fue investigar el efecto de una sección de ejercicios en la modificación de la imagen corporal. En especifico, observamos si una sección de practica deportiva o de actividad en un gimnasio podría ejercer influencia positiva en la imagen corporal - vista como una percepción puntual, evaluadora y efectiva en respecto de la propria apariencia. Los resultados muestran un incremento de la auto-imagen corporal (según la Escala de Estados de la Imagen Corporal, BISS) después de una hora de actividad en un gimnasio o de practica deportiva en una amuestra compuesta por 295 sujetos. Intensidad y divertimiento asociados a las actividades parecen haber sido factores claves para la elevación de los escores relacionados a la imagen corporal. Los resultados de la investigación pueden ofrecer importantes insumos para el tratamiento y prevención de los disturbios de la auto-imagen.

Em que pese o fato de que atletas e pessoas fisicamente ativas estarem geralmente mais satisfeitos com seu corpo que indivíduos sedentários, a atividade física parece ser responsável por influências tanto positivas quanto negativas em relação à imagem corporal. O objetivo deste estudo foi investigar o efeito de uma sessão de exercícios na modificação da imagem corporal. Especificamente, observamos se uma sessão de prática esportiva ou de atividade em academia poderia exercer influência positiva na imagem corporal, considerada como uma percepção episódica, avaliativa e afetiva a respeito da própria aparência. Os resultados mostram um incremento da autoimagem corporal (segundo a Escala de Estados de Imagem Corporal, BISS) depois de uma hora de atividade em academia ou prática esportiva em uma amostra composta por 295 sujeitos. Intensidade e divertimento associados às atividades foram, ao que parece, fatores-chave para a elevação de escores em relação à imagem corporal. Os resultados da pesquisa podem oferecer importantes implicações para o tratamento e prevenção de distúrbio de autoimagem.
