RESUMO
In this study, we investigated psychometric support for a version of the Multidimensional Assessment of Teamwork in Sport (MATS) that would be suitable for Brazilian athletes. Four translators participated in the back-translation of this instrument from English to Portuguese, two specialists synthesized the Portuguese and English back-translation versions, and 10 experts assessed the questionnaire items and judged their content validity. To evaluate structural validity, we performed confirmatory factor analysis (CFA). We evaluated internal item reliability with a sample of 447 athletes who completed the adapted measure (the MATS-B). Finally, 202 other athletes completed both the MATS-B and a second measure of collective efficacy (CEQS-B) to provide external validity correlates. With these data, the MATS-B now provides valid and reliable data supporting its use with Brazilian athletes in an adapted assessment tool that aligns with the conceptual framework of teamwork in sports.

In this study, we aimed to develop and psychometrically examine a self-efficacy scale for high-performance volleyball athletes. A literature review and interviews with 16 experts led to construction of item content. A preliminary version of the scale was then administered to 24 high-performing adult athletes, followed by administration of the scale to 300 Brazilian high-performing volleyball athletes (M age = 24.88, SD = 5.51 years; 55% male; 45% female). The definitive model contained 19 items, grouped into three factors (Self-Efficacy in the Game, Defensive Self-Efficacy in Volleyball, and Offensive Self-Efficacy in Volleyball). A Global Self-Efficacy score was evaluated through several statistical procedures that provided evidence of an adequate fit of the model to the data, and we showed internal reliability of the item content and invariance of the instrument for both sexes. These results support the instrument's test content, internal structure, and relation to other variables, indicating that the Volleyball Self-Efficacy Scale (VSES) can now be used to assess the self-efficacy of high performing Brazilian volleyball athletes.
RESUMO
The aim of this study was to psychometrically test the Volleyball Self-Efficacy Scale for Brazilian athletes from youth categories. The study was conducted in four stages, with four different sample groups. For content-based evidence analysis, a group of 20 athletes participated, with a mean age of 14.30 ± 1.17 years and practice time of 4.60 ± 2.10 years, for semantic analysis, after a group of four students, with a mean age of 35.75 ± 12.23 years and experience time 25.0 ± 11.02 years, to verify the semantic analysis and another group of 20 athletes, with a mean age of 14.45 ± 1.30 years and practice time 5.50 ± 2.20 years for the pilot study. To test the evidence based on the internal structure and the evidence based on other variables, a group of 454 base athletes, of both sexes, with a mean age of 14.33 ± 1.18 years and practice time 3.79 ± 2.13 years was verified. The results pointed to evidence based on content, evidence based on internal structure and evidence based on other variables, through convergent validity (collective efficacy and results of Confirmatory Factor Analysis) and discriminant (Average Variance Extracted and correlation between the dimensions of the VSES-B). The validation process of the Volleyball Self-Efficacy Scale for Base Athletes allows us to conclude that the instrument has good psychometric properties to measure self-efficacy, considering technical, tactical, conditioning and psychological skills of emotional cognitive self-control that are part of the sport context of the modality. In addition, it provides relevant information for the development of future psychometric research based on contemporary validity references.
El objetivo de este estudio fue probar psicométricamente la Escala de Autoeficacia del Voleibol para deportistas brasileños de categorías juveniles. El estudio se llevó a cabo en cuatro etapas, con cuatro grupos de muestra diferentes. Para el análisis de evidencia basada en contenido, participó un grupo de 20 deportistas, con una edad media de 14.30 ± 1.17 años y tiempo de práctica de 4.60 ± 2.10 años, para el análisis semántico, después de un grupo de cuatro académicos, con una edad media de 35.75 ± 12.23 años y tiempo de experiencia 25.0 ± 11.02 años, para verificar el análisis semántico y otro grupo de 20 deportistas, con una edad media de 14.45 ± 1.30 años y tiempo de práctica 5.50 ± 2.20 años para el estudio piloto. Para probar la evidencia basada en la estructura interna y la evidencia basada en otras variables, se verificó un grupo de 454 atletas de base, de ambos sexos, con una edad media de 14.33 ± 1.18 años y tiempo de práctica 3.79 ± 2.13 años. Los resultados apuntaron a evidencia basada en contenido, evidencia basada en estructura interna y evidencia basada en otras variables, mediante validez convergente (eficacia colectiva y resultados del Análisis Factorial Confirmatorio) y discriminante (Varianza Media Extraída y correlación entre las dimensiones del VSES-B). El proceso de validación de la Escala de Autoeficacia de Voleibol para Atletas de Base nos permite concluir que el instrumento tiene buenas propiedades psicométricas para medir la autoeficacia, considerando las habilidades técnicas, tácticas, condicionantes y psicológicas de autocontrol cognitivo emocional que forman parte del contexto deportivo de la modalidad. Además, proporciona información relevante para el desarrollo de futuras investigaciones psicométricas basadas en referencias de validez contemporáneas.

In sports context, the motivational climate has been widely studied since 2000, when the Perceived Motivational Climate in Sports Questionnaire-2 (PMCSQ-2) was published. Evaluating athletes' perceptions of the motivational climate created by the coach, this questionnaire has been validated and adapted for different countries, including Brazil. However, important psychometric properties of the Brazilian version present problems, such as poor fit indices and the almost exclusively male samples, make it unfeasible for use in future research. Thus, this study aimed to achieve a new process of cross-cultural adaptation, and search for validity evidence of the PMCSQ-2 for the Brazilian sports context to correct distortions, expand the sources of evidence of validity and ecological validity, and make it suitable for application in future research. The sample consisted of 501 athletes (349 males, 152 females) from different sports. The findings of the current study support the multidimensional hierarchical characteristic of the instrument, its factorial structure, and internal consistency. We concluded that the 33-item PMCSQ-2BR, distributed in two high-order scales (ego-involving and task-involving) with three subscales each, can be used to assess athletes' perceived motivational climate in the Brazilian sports context.
RESUMO
Abstract Introduction: The present systematic review aimed to compile the information available in the literature having to do with sport psychology regarding futsal and soccer players, in order to identify which psychological constructs are being investigated in these athletes and by means of which instruments and analysis techniques. Method: The search was carried out in the APA (PsycINFO), EBSCO (SportDiscus), PubMed, Web of Science, Scielo, Science Direct, Scopus, BVS and EMBASE databases, with the following descriptors: psychological construct; psychological factor; psychological variable; psychological phenomenon; soccer; futsal and athlete, in English, Spanish and Portuguese. Results: Initially, 66 studies met the established eligibility criteria. Of these, 46 studies were conducted with soccer players, 19 with futsal players and one with athletes who participate in both sports. The psychological constructs most studied in the soccer modality were anxiety, stress, motivation, coping, motivational climate, depression, self-efficacy and group cohesion. With regard to the futsal modality, the most studied psychological constructs were group cohesion, perfectionism, motivation, athlete satisfaction, leadership style, perceived parenting styles and burnout. Conclusions: Group cohesion was associated with several other psychological aspects of an individual nature, with cohesion being the construct of both modalities which is of the greatest interest to researchers possibly because it is a collective modality. It can be established that important psychological factors have not been studied in soccer and futsal modalities, especially among female athletes. Therefore, it is recommended that the research carried out with male athletes be extended to include female populations.
Resumo Introdução: O presente estudo de revisão sistemática procurou compilar informações disponibilizadas na literatura quanto aos estudos da psicologia do esporte em jogadores de futsal e futebol, com a finalidade de identificar quais construtos psicológicos estão sendo estudados nesse público e por quais instrumentos e técnicas de análise. Método: A busca foi realizada nas bases de dados APA (PsycINFO), EBSCO (SportDiscus), PubMed, Web of Science, Scielo, Science Direct, Scopus, BVS e EMBASE, com os seguintes descritores: construto psicológico; fator psicológico; variável psicológica; fenômeno psicológico; futebol; futsal e atleta, nos idiomas inglês, espanhol e português. Resultados: Foram selecionados 66 estudos por meio dos critérios de elegibilidade estabelecidos. Destes, 46 estudos foram conduzidos com jogadores de futebol, 19 com jogadores de futsal e um com atletas de ambas as modalidades. Os construtos psicológicos mais estudados na modalidade de futebol foram ansiedade, estresse, motivação, coping, clima motivacional, depressão, autoeficácia e coesão grupal. Os construtos psicológicos mais estudados na modalidade de futsal foram coesão de grupo, perfeccionismo, motivação, satisfação do atleta, estilo de liderança, estilos parentais percebidos e burnout. Conclusão: A coesão grupal foi associada a diversos outros aspectos psicológicos de natureza individual, sendo a coesão o construto de maior interesse dos pesquisadores de ambas as modalidades, possivelmente, por serem modalidades coletivas. Pode-se identificar que fatores psicológicos importantes não foram estudados nas modalidades de futebol e futsal, em especial junto a atletas do sexo feminino. Recomenda-se, assim, que pesquisas realizadas com atletas do sexo masculino sejam também conduzidas com a população feminina.

This three-part study aimed to translate, cross-culturally adapt, and validate the Collective Efficacy Questionnaire for Sports (CEQS) for Brazilian athletes. In Study 1, six translators and six specialists developed a Portuguese version of the CEQS (the CEQS-B), and 10 experts and 10 sports participants provided content validity evidence based on test content. In Study 2, 553 athletes completed the CEQS-B, and we provided evidence of construct and convergent validity for the test's internal structure through factor analysis and of reliability evidence based on the instrument's internal consistency and temporal stability. In Study 3, 79 athletes completed both the new CEQS-B and the Group Cohesion Questionnaire, and we provided evidence of concurrent validity for the CEQS-B, based on its relationship to other variables, with specific strong correlations between team task cohesion and collective efficacy among these participants. Overall, the results of this study support the use of the CEQS-B by researchers and professionals wishing to assess various sport athletes' self-perceived collective efficacy.

Collective efficacy, defined as a group's shared belief about its conjoint capability to organize and execute courses of action, plays a pivotal role in understanding the dynamics of sports teams, since it influences what individuals choose to do as team members, how much they invest in motivational terms to perform actions, how much they work collectively, and for how long they persist despite failure. Through a systematic review, it was investigated how collective efficacy has been assessed in the context of soccer and which indicators, attributes, and psychometric properties have been contemplated in the instruments used. Following the PRISMA guidelines, 22 articles were retrieved through electronic databases (APA PsycINFO; SPORTDiscus; Science Direct; BVS; Web of Science; Scopus; PubMed; and Scielo), using as descriptors, in English, Spanish, and Portuguese, collective efficacy and soccer, combined by the Boolean operators AND and OR. The study did not delimit the initial year of publication for the searches carried out, including all articles found until January 14, 2021 (date of the last update). The following eligibility criteria were adopted: scientific articles published in journals; original studies, which specified the instrument used to assess collective efficacy and carried out with soccer athletes. Five instruments (FCEQ, CEQS, CEI, CEC, and CEQsoccer) that evaluated technical-tactical and psychological attributes associated with collective efficacy in soccer players were identified. In most studies, psychometric properties were restricted to content validity and reliability (internal consistency), and there were no suitable validation processes for the instruments used to measure collective efficacy, which can be considered a limiting factor for understanding this psychological construct in soccer modality.

The low professional insertion of psychologists in Brazilian sports teams, as well as the Sport Psychology course being seldom offered in undergraduate Psychology courses, may reflect in the current scenario of scientific research in Brazil. It is still not clear what Graduate Programs (GPs) have adopted directions regarding the development of studies in Sport and Exercise Psychology (SEP) research fields since an assessment or mapping of scientific knowledge production in this area has not yet been performed involving Exercise and Sport Science and Psychology GPs. This study aimed at investigating institutional research and their themes in SEP from these graduate programs. Studies were selected and retrieved from a national database (Sucupira Platform), that contains all registered researches from all Exercise and Sport Science (n = 31) and Psychology (n = 84) GPs in the country. Data were analyzed through R software using text mining techniques, latent semantic analysis and K-means clustering. Results revealed that research involving SEP is predominantly being developed at Exercise and Sport Science GPs (n = 171; p < 0.01) in comparison to psychology GPs (n = 39), mostly located in the south and southeast regions of Brazil. This research has focused on the effects of physical exercise and quality of life, while Psychology GPs have analyzed sport as associated with health and education, as a way to promote social support and to study sports' psychological aspects. It was concluded that Exercise and Sport Science GPs had the most significant contribution to SEP. Investigations were focused on the interface of exercise with quality of life, health and education, with gaps existing in programs advancing in the studies on sports and performance.
RESUMO
ABSTRACT Recently, scholars have been sought to deepen research on a psycho-physiological phenomenon that can lead athletes to quit sports, known in the literature as sport-related burnout. The aim of the present integrative review study was to analyze psychological and performance variables associated with the burnout syndrome in adult athletes. Articles were searched on Pubmed, Web of Science, Scielo, Science Direct, Scopus and Apapsycnet electronic databases, using the following descriptors: burnout, sports and athletes, in both English and Portuguese. From the 15 selected studies, there was predominance of psychological variables associated with burnout over performance aspects. Negative correlations were found between burnout and basic psychological needs, intrinsic motivation and coping strategies. Positive correlations were found between burnout and competitive level, training volume, years of training, perfectionism and overtraining. There were no data on performance increase or decrease related to burnout in adult high-performance athletes, which shows a gap in the literature and encourages new investigations.
RESUMO Recentemente, têm-se procurado aprofundar os estudos sobre o fenômeno psicofisiológico que pode levar atletas ao abandono de sua atividade esportiva conhecido na literatura como burnout no contexto esportivo. O objetivo do presente estudo de revisão integrativa foi analisar as variáveis psicológicas e de desempenho associadas à síndrome de burnout em atletas adultos. Buscaram-se artigos nas bases de dados eletrônicas Pubmed, Web Of Science, Scielo, Science Direct, Scopus, Apapsycnet através dos descritores burnout (burnout), sports (esportes) e athletes (atletas). Constatou-se que houve uma predominância das variáveis psicológicas associadas ao burnout em relação a aspectos de desempenho. Foram encontradas correlações negativas entre necessidades básicas psicológicas, motivação intrínseca, estratégias de coping e burnout, e correlações positivas com nível competitivo, volume de treinamento, tempo de treino, perfeccionismo, overtraining e burnout. Não foram encontrados resultados que inferissem aumento ou queda de desempenho em atletas de alto rendimento relacionados ao burnout, o que sucinta uma lacuna na literatura para novas investigações.

ABSTRACT The aim of this systematic review was to analyze the cross-cultural adaptation and validation processes of Borg's Rating of Perceived Exertion Scale (6-20) and its instructions during exercise in adults and the elderly. The study was conducted using databases that include the areas of health, sports and psychology (Pubmed, ScienceDirect, Bireme (BVS), PsycINFO, SportDiscus and Scopus), and descriptors in the English and Portuguese languages were standardized for all databases ("exercise" / "exercicio", "validity" / "validade", "borg scale" / "escala de borg"; "perceived exertion" / "percepção de esforço" and "validation" / "validação"). Among the 1,488 items found, 14 articles were selected for analysis. The main findings were that cross-cultural adaptation (Cantonese and Japanese) was reported in only four articles. The lowest-scored criteria for methodological quality were related to the concept of perceived exertion, and the instructions for use and familiarization with Borg's scale. The results indicate that the majority of the studies did not apply the cross-cultural adaptation process and additionally, that concurrent validity was the only validation method reported. Therefore, it is necessary to carry out the cross-cultural adaptation of Borg's Scale (6-20), mainly in the Portuguese language, in addition to other types of validation in order to ensure more accurate results.
RESUMO O objetivo dessa revisão sistemática foi analisar os processos de adaptação transcultural e validação da Escala de Percepção Subjetiva de Esforço de Borg (6-20) e de suas instruções durante o exercício em adultos e idosos. A busca foi realizada nas bases de dados da área da saúde, esporte e psicologia (Pubmed, ScienceDirect, Bireme (BVS), PsycINFO, SportDiscus e Scopus) e os descritores em inglês e português foram padronizados para todas as bases de dados ("exercise"/"exercício"; "validity"/"validade"; "borg scale"/"escala de borg"; "perceived exertion"/"percepção de esforço"; e "validation"/"validação"). Entre os 1488 artigos encontrados, foram selecionados 14 artigos para análise. Os principais resultados encontrados foram que a adaptação transcultural (Cantonês e Japonês) foi reportada em apenas quatro artigos. Os critérios mais baixos de qualidade metodológica foram aqueles relacionados a definição de percepção de esforço, a instrução e familiarização com a Escala. Os resultados indicam que a maioria dos estudos não realizou o processo de adaptação transcultural e além disso, só a validade concorrente foi utilizada como método de validação. Portanto, é necessário realizar adaptação transcultural da Escala de Borg (6-20) principalmente na língua portuguesa, além dos diferentes tipos de validação para se obter resultados mais precisos.

Resumo Compreender a relação entre ansiedade-estado pré-competitiva e desempenho esportivo se constitui em importante meio para ajudar os esportistas a diagnosticar e controlar emoções. O presente estudo pretendeu: a) comparar o nível de ansiedade pré-competitiva entre atletas homens e mulheres, das equipes finalistas da Taça Paraná de Voleibol 2011; b) comparar os níveis de ansiedade pré-competitiva entre as equipes campeã e vice-campeã masculina, bem como entre as equipes campeã e vice-campeã feminina; c) comparar os níveis de ansiedade pré-competitiva dos atletas titulares e reservas, para as equipes de ambos os sexos; d) verificar a relação entre os níveis de ansiedade pré-competitiva e o tempo de prática dos atletas das equipes masculinas, bem como das equipes femininas. Participaram do estudo quatro equipes infanto-juvenis, finalistas da Taça Paraná 2011, totalizando 24 atletas do sexo feminino e 23 do sexo masculino (idade 16,16 ± 0,34 anos) e tempo de prática (4,97 ± 1,99 anos). Para avaliar a ansiedade pré-competitiva, utilizou-se o instrumento CSAI-2. As coletas ocorreram 30 minutos antes do início dos jogos finais. De forma geral, as equipes finalistas apresentaram níveis de ansiedade geral pré-competitiva similares, embora tenham sido encontradas diferenças significativas entre atletas mulheres titulares e reservas em relação à autoconfiança, sendo que as titulares apresentaram médias mais elevadas neste aspecto.(AU)
Abstract Understanding the relationship between pre-competitive state anxiety and sports performance are an important means to help sportsmen to diagnose and manage emotions. The present study aimed to: a) compare the level of pre-competitive anxiety among athletes men and women, the finalist teams of Paraná Cup Volleyball 2011; b) to compare the levels of pre-competitive anxiety among male champion teams and runners-up, as well as between female champion teams and runners-up; c) compare the levels of pre-competitive anxiety and reserves holders athletes for teams of both sexes; d) verify the relationship between the levels of pre-competitive anxiety and practice time for athletes of men's teams and the women's teams. Study participants were four youth teams, Paraná Cup finalists in 2011, totaling 24 female athletes and 23 male athletes (age 16.16 ± overall 0.34 years) and practice time 4.97 ± 1.99 years . To evaluate the pre-competitive anxiety, used the instrument CSAI-2. Sample occurred 30 minutes before the start of finals games. In general, the finalist teams had higher levels of general pre-competitive anxiety similar, although statistically significant differences between women athletes holders and reserves have been found in relation to the self-confidence, and the holders had higher average in this aspect.(AU)

BACKGROUND AND OBJECTIVES: Failed back surgery syndrome refers to a condition in which a patient has undergone back surgery with a poor outcome. This syndrome leads to losses in daily living activities and hinders the return to physical exercise. The objective of this study was to analyze the relation between chronic low back pain and functional capacity and the physical activity level of these patients. METHODS: Cross-sectional study comprising 57 patients, mean age 51.07±12.93 years, who underwent low back surgery. These patients were divided into two groups, according to the presence of chronic low back pain. All patients filled in a questionnaire that covered demographic data, visual analog scale for pain, Rolland-Morris Questionnaire to evaluate functional incapacity and International Physical Activity Questionnaire to measure physical activity level. RESULTS: The following predominated: women (77%), obese (49%), surgery for spinal disc herniation (80%), underwent one low back surgery (52%). Patients with chronic low back pain refer a greater perception of disability and 81% of this group showed an average of 3.53±3.51 points in Roland-Morris. Chronic low back pain had no influence on the different levels of physical activity demonstrated in patients with chronic low back pain and results of the International Physical Activity Questionnaire showed no significant difference between the groups (p=0.54). CONCLUSION: These findings indicate that there were other factors beyond chronic pain interfering with the physical activity level in these groups and further studies to explore lifestyle, physical exercise adherence and other dimensions of pain are still needed. Results contribute to the understanding and management of patients with chronic low back pain. .
RESUMO
O papel da autoeficácia no desempenho é foco de estudo no âmbito esportivo. O objetivo desta revisão integrativa foi verificar os instrumentos empregados para mensurar a autoeficácia relacionada ao desempenho esportivo e identificar suas propriedades psicométricas. Buscaram-se artigos nas bases de dados Eric, Scopus e APA (Psycnet), Scielo ScienceDirect e Pubmed com os descritores self-efficacy, sports, performance. Dos 13 estudos selecionados para análise, constatou-se que a maioria propôs instrumentos específicos para a pesquisa, seguindo recomendações do guia de construção de medidas de autoeficácia; apenas um artigo apresentou o processo de validação; a consistência interna foi a propriedade psicométrica mais reportada; não houve referência à reprodutibilidade dos instrumentos e tampouco divulgação dos instrumentos utilizados nas pesquisas. Conclui-se que a reprodutibilidade dos instrumentos permitiria maior confiabilidade na análise dos resultados e controle de variáveis cognitivas que afetam o rendimento esportivo e que um padrão ouro de avaliação da autoeficácia em contexto esportivo específico se faz necessário.
The role of self-efficacy on performance is the focus of study in sports. The aim of this integrative review was to assess the instruments used to measure self-efficacy related to sports performance and identify its psychometric properties. We searched for articles in databases Eric, Scopus and APA (Psycnet), Scielo ScienceDirect and Pubmed with descriptors self-efficacy, sports, performance. Of the 13 studies selected for analysis, it was found that most proposed specific instruments for research, following recommendations of the guide construction of measures of self-efficacy; just one article presented the validation process, the internal consistency was reported more psychometric property; there was no reference to the reproducibility of the instruments nor disclosure of the instruments used in research. It is concluded that the reproducibility of the instruments allow greater reliability in the results analysis and control of cognitive variables that affect sport performance and that a gold standard for assessing self-efficacy in specific sporting context is necessary.
RESUMO
The prevalence of overweight and obesity in patients with fibromyalgia is high, which makes these patients more likely to trigger metabolic changes. It is also uncertain whether the clinical manifestations of fibromyalgia alter the metabolism in these patients. This study investigates the influence of adiposity indicators and presence of fibromyalgia on leptin and acylated ghrelin levels, which are hormones responsible for controlling energy homeostasis. Seventeen women with fibromyalgia (patients) and fifteen healthy women (controls) were evaluated. Pain intensity, physical activity level characteristics and leptin and acylated ghrelin levels were assessed. General linear models, using a main-effects model, were used to test the effect of fibromyalgia (patients vs. controls) on the relationship of leptin and acylated ghrelin with anthropometric indicators [body mass index, waist circumference (WC) and WC by height]. Patients showed higher leptin levels (controls: 9.1 ± 6.7 vs. patients: 22.4 ± 10.6 ng/mL; p < 0.01) and lower acylated ghrelin levels (controls: 188.7 ± 103.4 vs. patients: 126.7 ± 47.8 pg/mL; p = 0.04). The anthropometric variables, entered into linear models as independent variables, significantly influenced both leptin and acylated ghrelin levels (p < 0.01). The explained variance (R(2)) of the models containing leptin was higher (R(2) = 0.52-0.61) compared to the models containing acylated ghrelin (R(2) = 0.24-0.27). When analyzing the influence of the presence of fibromyalgia (study group: women with fibromyalgia vs. healthy women), only the leptin levels were influenced. High leptin levels independent of adiposity in women with fibromyalgia may be associated with the clinical condition of this syndrome.

INTRODUCTION: Fibromyalgia (FM) is a chronic pain condition that causes impaired functional capacity, possibly through the adoption of sedentary behaviour. However, little is known regarding physical activity level and its relationship with physical performance in women with FM. OBJECTIVES: To compare physical activity level, assessed using the International Physical Activity Questionnaire (IPAQ), and physical performance, measured using the six-minute walk test (6MWT), in women with and without FM, and to examine the possible relationships between physical activity level and physical performance in both groups. METHODS: The study included 30 women diagnosed with FM (patients) and 28 healthy women (controls) who answered the IPAQ and performed the 6MWT. RESULTS: Patients and controls self-reported similar physical activity level, considering both the total score and all IPAC subcomponents (P > 0.05). However, the FM patients had worse physical performance in the 6MWT (patients, 441.8 ± 84.1 m vs. controls, 523.9 ± 80.3 m; P < 0.01). There were no relationships between the distance walked in the 6MWT and the IPAQ variables for the control group. However, the distance walked by patients in the test showed a significant correlation (P < 0.05) with the total score and the subcomponents transport, household activities, and physical activities of moderate intensity in the IPAQ. CONCLUSIONS: Women with FM had physical activity levels similar to women without FM but exhibited worse physical performance. This functional impairment may be related to lifestyle adopted because there was a relationship between physical activity level and physical performance in those patients.

O objetivo da pesquisa foi determinar a prevalência de mulheres com sintomas de bulimia nervosa frequentadoras de academia de ginástica e verificar, dentre as praticantes que apresentam traços bulímicos, qual a frequência de utilização do exercício físico como forma compensatória. Participaram do estudo 197 mulheres matriculadas em academias de ginástica da cidade de Marechal Cândido Rondon - PR (28,7±9,9 anos). Para avaliar o quadro de bulimia utilizou-se o Teste de Investigação Bulímica de Edingurgh (BITE) e uma anamnese estruturada pelos pesquisadores para atender interesses do estudo. Na análise dos dados foi utilizada a estatística descritiva e a frequência amostral pelo programa estatístico SPSS for Windows 11.5. A prevalência de sintomas de bulimia foi de 3%. A prevalência de traços bulímicos foi de 11,2%. Dos indivíduos que apresentaram traços bulímicos, 59,1% afirmaram praticar exercício físico após episódios de alimentação exagerada. Estes resultados podem indicar que esse comportamento compensatório através da prática de exercício físico pode levar as mulheres a procurar as academias de ginástica.
The research objective was to determine the prevalence of women with symptoms of bulimia nervosa attending the gym and check out the practitioners who show bulimic traces, and how often they use the exercise as a compensatory way. The study included 197 women enrolled in gyms in the city of Marechal Cândido Rondon - PR (28.7 ± 9.9 years). To evaluate the framework of bulimia it was used the Bulimic Investigatory Test of Edingurgh (BITE) and a structured interview by the researchers to meet the interests of the study. For the data analysis it was used descriptive statistics and frequency sampling by the statistical program SPSS for Windows 11.5. The prevalence of symptoms of bulimia was 3%. The prevalence of bulimic traits was 11.2%. From the individuals that show bulimic traits, 59.1% reported physical exercise after episodes of over-eating. These results may indicate that this compensatory behavior through physical exercise can cause women to seek out gyms.
El objetivo de la investigación fue determinar la prevalencia de mujeres que frecuentan al gimnasio y presentan síntomas de la bulimia nerviosa, observar en los practicantes que presentan rasgos de bulimia, con qué frecuencia se utilizan del ejercicio como una forma de compensación. El estudio incluyó a 197 mujeres que participaron en los gimnasios en la ciudad de Marechal Cândido Rondon - PR (28,7 ± 9,9 años). Para evaluar el marco de la bulimia se utilizó la Prueba Investigadora de la Bulimia de Edingurgh (BITE) y una entrevista estructurada por los investigadores para satisfacer a los intereses del estudio. En el análisis de los datos se utilizó estadística descriptiva y la frecuencia de muestra por el programa estadístico SPSS 11.5 for Windows. La prevalencia de síntomas de la bulimia fue de 3%. La prevalencia de rasgos bulímicos fue del 11,2%. De las personas que tienen rasgos bulímicos, el 59,1% reportó el ejercicio físico después de los episodios de comer en exceso. Estos resultados indican que este comportamiento compensatorio a través del ejercicio físico hace con que las mujeres busquen a los gimnasios.
RESUMO
INTRODUÇÃO: A fibromialgia (FM) é uma condição dolorosa crônica que causa comprometimento da capacidade funcional, possivelmente pela adoção de um comportamento sedentário. No entanto, pouco se sabe sobre o nível de atividade física (NAF) e sua relação com o desempenho físico em mulheres com FM. OBJETIVOS: Comparar o NAF, avaliado por meio do International Physical Activity Questionnaire (IPAQ), e o desempenho físico, mensurado pelo teste de caminhada de 6 minutos (TC6) de mulheres com e sem FM, além de investigar possíveis relações entre NAF e desempenho físico em ambos os grupos. MÉTODOS: Participaram do estudo 30 mulheres com o diagnóstico de FM (pacientes) e 28 mulheres saudáveis (controles) que responderam ao IPAQ e realizaram o TC6. RESULTADOS: Pacientes e controles autorrelataram similar NAF, considerando tanto o escore total quanto todos os subcomponentes do IPAQ (P > 0,05). Porém, as pacientes apresentaram pior desempenho físico no TC6 (pacientes: 441,8 ± 84,1 m vs. controles: 523,9 ± 80,3 m; P < 0,01). Não existiram relações entre a distância caminhada no TC6 e as variáveis do IPAQ para o grupo controle. Entretanto, para as pacientes, a distância caminhada no teste apresentou correlações significativas (P < 0,05) com o escore total e com os subcomponentes transporte, atividades domésticas e atividades físicas de intensidade moderada do questionário IPAQ. CONCLUSÕES: Mulheres com FM apresentaram NAF similar às mulheres sem FM, mas pior desempenho físico. Esse comprometimento funcional pode estar relacionado ao estilo de vida adotado, uma vez que houve relação entre o NAF e o desempenho físico nessas pacientes.
INTRODUCTION: Fibromyalgia (FM) is a chronic pain condition that causes impaired functional capacity, possibly through the adoption of sedentary behaviour. However, little is known regarding physical activity level and its relationship with physical performance in women with FM. OBJECTIVES: To compare physical activity level, assessed using the International Physical Activity Questionnaire (IPAQ), and physical performance, measured using the six-minute walk test (6MWT), in women with and without FM, and to examine the possible relationships between physical activity level and physical performance in both groups. METHODS: The study included 30 women diagnosed with FM (patients) and 28 healthy women (controls) who answered the IPAQ and performed the 6MWT. RESULTS: Patients and controls self-reported similar physical activity level, considering both the total score and all IPAC subcomponents (P > 0.05). However, the FM patients had worse physical performance in the 6MWT (patients, 441.8 ± 84.1 m vs. controls, 523.9 ± 80.3 m; P < 0.01). There were no relationships between the distance walked in the 6MWT and the IPAQ variables for the control group. However, the distance walked by patients in the test showed a significant correlation (P < 0.05) with the total score and the subcomponents transport, household activities, and physical activities of moderate intensity in the IPAQ. CONCLUSIONS: Women with FM had physical activity levels similar to women without FM but exhibited worse physical performance. This functional impairment may be related to lifestyle adopted because there was a relationship between physical activity level and physical performance in those patients.

O medo de cair é um dos principais problemas em indivíduos pós acidente vascular encefálico (AVE). A imaginação pode ser uma experiência sucedida para diminuir este aspecto. O objetivo deste estudo foi verificar o efeito de um programa de imaginação de curto prazo no medo de quedas em indivíduos pós-AVE. Sete indivíduos acometidos por AVE participaram do estudo. A Escala Internacional de Eficácia de Quedas (FES-I-Brasil) foi aplicada antes (PRÉ), depois (PÓS) e sete dias após a intervenção (RET). Foram realizadas quatro sessões de familiarização e seis de prática da imaginação. Não houve diferença significativa no escore total da FES-I-Brasil após intervenção (p=0,46), exceto na tarefa subir/descer escadas (PRÉ e PÓS, p=0,04; PRÉ e RET; p=0,01). Apesar da melhoria na tarefa subir/descer escadas, alterações nos demais itens da escala não foram encontradas o que pode representar um efeito relativamente reduzido do programa de imaginação de curto prazo.
The fear of falling is one of the main problems with subjects after stroke. Imagery could be one succeed experience to decrease this issue. The aim of this study was to verify the effect of a short-time imagery intervention in fear of falling in subjects after stroke. Seven individuals affected by stroke participated in the study. The Falls Efficacy Scale International (FES-I-Brazil) were used before (PRE), after (POST) and seven days after intervention (RET). Four session of familiarization and six of imagery were performed. There were no difference in FES-I-Brazil score after intervention (p=0.46), except in up/down stairs task (PRE and POST, p=0.04; PRÉ and RET, p=0.01). Although, the improvement in up/down stairs task, no more changes were found in the scale items, which could represent a relatively reduced effect of short-time imagery intervention.
