RESUMEN

ABSTRACT Introduction: Circadian rhythms can impact athletes' sports performance, where the plateau occurs between 15 and 21 hours. Swimming is a peculiar case, as athletes perform training and final sessions in competitions at different times, as in the Rio2016 Olympic Games for example, where the semifinal and final competitions took place from ten o'clock at night. Objectives: (1) to present the protocol of an intervention performed with elite athletes of the Brazilian swimming team during the 2016 Olympic Games in Rio; (2) to find out whether the time at which the competitions were held affected the swimming performances of these athletes during the competition. Materials and Methods: Fourteen athletes of the Brazilian swimming team (males: n= 10; 71% and females: n= 4; 29%) participated in the study. They were followed up during two preparation periods (baseline and intervention) for the 2016 Olympic Games in Rio during June and July 2016. During the competition, we recorded the Reaction Time (RT) and Competition Time (CT) of each athlete in different modalities. The intervention strategies used were light therapy and sleep hygiene. The values of RT at the starting block and CT were registered and conferred with the official results. Results: The athletes showed a decrease in the total time awake (Δ = −13%; Effect size [ES] = 1.0) and sleep latency (Δ = −33%; ES = 0.7), and an increase in total sleep time (Δ = 13%; ES = 1.1; p = 0.04) between the baseline and the period of the intervention, pre-competition. We identified an improvement in the RT (Δ = −2.2% to −1.0%; ES = 0.2 to 0.5) during the competition only for the athletes who participated in the competition finals. Conclusion: We conclude that the intervention carried out was effective in mitigating any negative influence of competition time on the RT and CT of elite athletes of the Brazilian swimming team. Level of evidence II; Prospective comparative study.


RESUMO Introdução: Os ritmos circadianos podem exercer impacto no desempenho esportivo dos atletas, onde o platô ocorre entre as 15 e 21 horas. A natação é um caso peculiar, uma vez que os nadadores realizam sessões de treinamento e provas finais em competições em diferentes horários, como por exemplo, nos Jogos Olímpicos Rio2016, onde as competições semifinais e finais da natação ocorreram a partir das 22 horas. Objetivos: O presente estudo teve como objetivos: (1) apresentar o protocolo de uma intervenção realizada com atletas de elite da equipe de natação brasileira durante os Jogos Olímpicos Rio 2016; (2) identificar se o desempenho dos atletas de natação foi afetado devido aos horários das provas durante a competição. Materiais e Métodos: Participaram do estudo 14 atletas da equipe de natação brasileira (masculino: n= 10; 71% e feminino: n= 4; 29%). Foi realizado acompanhamento dos atletas durante dois períodos de preparação (baseline e intervenção) para os Jogos Olímpicos Rio2016 nos meses de junho e julho de 2016. Durante a competição, foi realizado o registro do Tempo de Reação (TR) e Tempo de Prova (TP) de cada atleta nas diferentes modalidades. As estratégias de intervenção utilizadas foram: terapia de luz e higiene do sono. Os valores de TR no bloco de partida e TP foram registrados e conferidos com os resultados oficiais. Resultados: Os atletas apresentaram decréscimo no tempo total de vigília (Δ = −13%; Tamanho do Efeito (TE) = 1,0) e latência de sono (Δ = −33%; TE = 0,7), e aumento do tempo total de sono (Δ = 13%; TE = 1,1; p = 0,04) entre o baseline e o período de intervenção pré-competição. Nós identificamos melhorias no TR (Δ = −2,2% à −1,0%; TE = 0,2 a 0,5) ao longo da competição somente para os atletas que participaram da fase final da competição. Conclusão: Concluímos que a intervenção realizada foi efetiva para minimizar qualquer influência negativa do horário da competição sobre o TR e TP dos atletas de elite da natação brasileira. Nível de evidência II; Estudo prospectivo comparativo.

RESUMEN

BACKGROUND: Fatigue is a frequent symptom in patients with primary Sjögren's syndrome (pSS) and can be a cause of or be associated with sleep disorders. OBJECTIVE: To assess the sleep quality of pSS patients and its relationship with fatigue and disease activity. DESIGN AND SETTING: Analytical observational study conducted at an exercise psychobiology laboratory. METHODS: Sleep quality was evaluated using the Pittsburg sleep quality index (PSQI) and actigraphy. Fatigue was evaluated through the Profile of Fatigue and Discomfort - Sicca Symptoms Inventory (PROFAD-SSI-SF) and a visual analogue scale for fatigue (VAS-fatigue). Disease activity was evaluated using a visual analogue scale for pain (VAS-pain), EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) and Disease Activity Index (ESSDAI). We summarized the data through descriptive statistics. RESULTS: A total of 50 female patients with pSS, of average age 56.4 years, were included in the study; 80% presented low disease activity. The total PSQI score showed that 74% had poor sleep. The actigraphy showed mean sleep latency of 26.2 minutes and mean nightly awakening of 48.2 minutes (duration of wakings after sleep onset, WASO). There were correlations between PSQI and VAS-pain, VAS-fatigue, PROFAD-SSI and ESSPRI. Actigraphy showed a correlation between the duration of WASO and ESSDAI. CONCLUSION: The present study provides important information regarding correlations between sleep disorders and disease activity. There is a need for proper control over disease activity and for development of strategies to help patients to sleep better in order to diminish their fatigue.

RESUMEN

ABSTRACT Introduction: Muscle injuries are the most frequent cause of physical disability in sports, representing a large percentage of all sports injuries. In high-performance sports in particular, there is great interest in optimizing the process of diagnosis and rehabilitation of muscle injuries in order to reduce the amount of time taken off by athletes due to their injuries. Infrared thermography, or cutaneous thermometry, is a technique used for complementary investigation of pain. It provides thermal imaging with an infrared camera, to measure the surface temperature of the body. Objective: To conduct a systematic review of the use of thermography as a functional evaluation for the identification and prevention of muscle injuries, and of the control variables used in its applicability. Methods: A systematic review was conducted in the MEDLINE, ResearchGate and Scielo databases, using the search terms: "thermography", "muscle injury", "rehabilitation" and "diagnosis", searching on articles published from 2000 to 2017, in Portuguese, English and Spanish. The eligibility criteria for the studies was the use of thermography as an outcome, and the reporting of standards for evaluating skin temperature variation in athletes. Results: Following the systematic review, 94 studies were retrieved. Of these, only 12 met the criteria for inclusion in the study. Conclusion: Thermography is a suitable tool for the evaluation and prevention of muscle injuries in athletes, and care should be taken with the control variables during its use. The most efficient variables for capturing the thermographic image appear to be an environment with a temperature of between 18 and 25°C, for 15 minutes for acclimatization, and with the individual placed in a pre-determined position, depending on the body segment being evaluated, without contact with another object. Level of evidence I; Systematic review.

RESUMEN

INTRODUCTION: Physical exercise at high altitude has become constant. However, the risks associated with this type of exercise represent a major concern, considering the influence of important stressors such as hypoxia and physical exercise on psychobiological and physiological responses. OBJECTIVE: Analyze the mood state and behavior of physiological variables of volunteers subjected to a progressive loading protocol until they reached maximum volitional exhaustion, both at sea level and at a simulated altitude of 4500 meters. METHOD: For both conditions studied, the volunteers responded to two instruments that assess mood responses: The Brunel Mood Scale and the Visual Analogue Mood Scale. They also underwent blood sampling to measure blood lactate levels and to evaluate oxygen-hemoglobin saturation. These procedures were performed before, immediately after, and 30 and 60 minutes after the end of the protocol. RESULTS: Hypoxia triggered negative effects on mood responses, especially when compared to sea level conditions. An increase in fatigue level (p=0.02) and mental confusion (p=0.04) was observed immediately after the exercise session, and reduction of vigor (p=0.03) was noted at 30 minutes, accompanied by a reduction in oxygen-hemoglobin saturation immediately after the session and at 30 minutes. There was also an increase in blood lactate levels immediately after the session (p=0.006). CONCLUSION: The particularities of the hypoxic environment associated with maximum exercise are able to cause a deterioration of mood and physiological responses, which can negatively modulate physical performance. This is a cross-sectional clinical study.


INTRODUÇÃO: Prática de exercícios físicos em elevadas altitudes tem se tornado constante. Entretanto, os riscos associados a esta representam uma grande preocupação, considerando a influência de importantes agentes estressores, como hipóxia e exercício físico, sobre as respostas psicobiológicas e fisiológicas. OBJETIVO: Analisar o perfil do humor e o comportamento de variáveis fisiológicas de voluntários submetidos a um protocolo de cargas progressivas até a Exaustão Voluntária Máxima no nível do mar e em altitude simulada de 4.500 metros. MÉTODOS: Para ambas as condições estudadas, os voluntários responderam a dois instrumentos que avaliam as respostas do humor, Escala de Humor de Brunel e o Visual Analogue Mood Scale, e foram submetidos à coleta de sangue para verificar a concentração de lactato sanguíneo, bem como para avaliar a saturação de oxi-hemoglobina. Esses procedimentos foram realizados antes, imediatamente depois e 30 e 60 minutos após o término do protocolo. RESULTADOS: A hipóxia desencadeou efeitos negativos sobre as respostas de humor, principalmente com relação ao nível do mar. Verificou-se aumento da fadiga (p = 0,02) e da confusão mental (p=0,04) imediatamente após a prática e redução do vigor (p = 0,03) aos 30 minutos; acompanhadas da diminuição da saturação da oxi-hemoglobina imediatamente após e aos 30 minutos; constatou-se ainda, o aumento da concentração de lactato sanguíneo no momento imediatamente após (p = 0,006). CONCLUSÃO: As particularidades do ambiente hipóxico associadas à realização do exercício físico máximo são capazes de piorar o estado de humor e as respostas fisiológicas, o que pode modular negativamente o desempenho físico. Este estudo é do tipo clínico transversal.

RESUMEN

OBJECTIVES: Obesity is a multifactorial disease characterized by the presence of the pro-inflammatory state associated with the development of many comorbidities, including bone turnover marker alterations. This study aimed to investigate the role of the inflammatory state on bone turnover markers in obese adolescents undergoing interdisciplinary weight loss treatment for one year. SUBJECTS AND METHODS: Thirty four post-pubescent obese adolescents with primary obesity, a body mass index (BMI) greater than > 95th percentile of the CDC reference growth charts, participated in the present investigation. Measurements of body composition, bone turnover markers, inflammatory biomarkers and visceral and subcutaneous fat were taken. Adolescents were submitted to one year of interdisciplinary treatment (clinical approach, physical exercise, physiotherapy intervention, nutritional and psychological counseling). RESULTS: Reduction in body mass, body fat mass, visceral and subcutaneous fat, as well as, an increase in the body lean mass and bone mineral content was observed. An improvement in inflammatory markers was seen with an increase in adiponectin, adiponectin/leptin ratio and inteleukin-15. Moreover, a positive correlation between the adiponectin/leptin ratio and osteocalcin was demonstrated. Further, both lean and body fat mass were predictors of osteocalcin. Negative associations between leptin with osteocalcin, adiponectin with Beta CTX-collagen, and visceral fat with adiponectin were observed. CONCLUSIONS: It is possible to conclude that the inflammatory state can negatively influence the bone turnover markers in obese adolescents. In addition, the interdisciplinary weight loss treatment improved the inflammatory state and body composition in obese adolescents. Therefore, the present findings should be considered in clinical practice.

RESUMEN

a) to measure individual variations in body mass (BM), sum of skinfolds (SSF) and energy intake of Paralympic track and field athletes b) to evaluate whether individual consumption of macronutrients meets recommended levels in three distinct periods of training. Methods: Ten Paralympic track and field athletes were evaluated during three periods: 1) end of season, 2) after vacation, and 3) preparation for the Paralympic Games London 2012. Food history and the 24-hour Dietary Recall methods provided information on daily food intake. To assess changes in body composition, we measured skinfolds and BM. Descriptive statistics were utilized to describe individual results. Results: BM varied among athletes and phases, but most (n=8) had higher SSF after vacation. Four athletes reported an increase in energy intake of more than 500 kcal during their vacation period, while eight athletes reported maintaining their intake in the preparatory phase for the competition. Carbohydrate intake was adequate for most athletes in the end of season period and in the preparatory phase for competition, and most athletes had reduced lipid intake after vacation and in the preparatory phase. Conclusion: We observed important variations in BM and SSF, in food intake and macronutrients between the three evaluated periods. The nutritional status of the athletes suggests that inadequacies that might affect the performance of sprinters and middle-distance runners are more likely to occur during the preparatory period before competitions.(AU)

RESUMEN

Introducción: Conocer el perfil psicobiológico de un deporte de equipo es importante para definir el trabajo y también en la preparación para las competiciones. El objetivo de este trabajo fue elaborar un perfil psicobiológico del equipo de atletismo paralímpico durante un período de 7 meses. Material y métodos: Diecinueve atletas del atletismo brasileño fueron evaluados al final de la temporada, al comienzo de la temporada, y previamente a la competición. Las evaluaciones se realizaron mediante los cuestionarios siguientes: Perfil de estados de ánimo, Escala de depresión de Beck, Cuestionario de Pittsburg de calidad de sueño, Escala de somnolencia de Epworth e Inventario de la escala de ansiedad rasgo-estado. Resultados: La mayoría de los atletas mostraron un nivel de ansiedad rasgo-estado medio en el final y el comienzo de la temporada. Hubo diferencia entre: época previa a la competición y el final de la temporada, en el dominio de vigor, que se incrementó en el período precompetición; previa a la competición y el comienzo de la temporada en la duración total del sueño, con un aumento en la precompetición; el principio y el final de la temporada, en la latencia del sueño con una disminución en el comienzo de la temporada. Conclusiones: El período durante la temporada deportiva puede alterar las variables psicobiológicas, tales como bajo vigor, somnolencia diurna, y una mayor latencia de sueño al final de la temporada y la mala calidad del sueño al comienzo de la temporada. Por el contrario, la buena calidad del sueño y alto vigor en la etapa previa a la competición favorecen el rendimiento deportivo (AU)


Introduction: Determining the psychobiological profile of a team sport is important for defining The work to be performed in each phase, as well as in preparation for future competitions. The aim of this study was to draw a profile of mood states, depression, sleep quality, sleepiness and anxiety, of a Paralympic athletics team over a seven-month period. Materials and methods: An assessment was made of 19 athletes from the Brazilian athletics team at the end of season, beginning of season, and pre-competition. The assessments were performed using following questionnaires: profile of mood states, Beck Depression Inventory, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and the State-Trait Anxiety Inventory. The results were expressed as the mean and standard deviation, and the significance level was set at p < 0.05. Results: Most of the athletes exhibited a median level of trait-state anxiety at the end and at the beginning of the season. There was difference between: pre-competition and the end of season in the vigor domain, which was increased in the pre-competition; pre-competition and the beginning of the season in the total duration of sleep, with an increase in the pre- competition; the beginning and the end of the season, in sleep latency, with a decrease at the beginning of the season (AU)

RESUMEN

ABSTRACT Objective To investigate the applicability of predictive equations for resting energy expenditure (REE) in obese individuals with obstructive sleep apnea (OSA) and the effects of OSA severity on REE. Materials and methods Twenty-nine obese men, 41.5 ± 7 years old, with moderate and severe OSA were recruited. All subjects were submitted to a clinical polysomnography, body composition, and indirect calorimetry measurements. REE was also predicted by three different equations: Harris and Benedict (1919), Cunningham (1990), and DRI (2002). Results No effects of OSA severity on REE were found. The measured REE (2416.0 ± 447.1 kcal/day) and the REE predicted by equations were different from each other (F = 2713.88; p < 0.05): Harris and Benedict (2128.0 ± 245.8 kcal/day), Cunningham (1789.1 ± 167.8 kcal/day) and DRI (2011.1 ± 181.4 kcal/day). Pearson correlations showed a moderate positive correlation between the REE measured and predicted by all equations. Conclusion Our findings suggest that predictive equations for REE underestimate the energy expenditure in obese patients with sleep apnea. Also, no effects of OSA severity on REE were found.

Traffic accidents and resulting injuries and deaths have become a global epidemic. In Brazil, most professional drivers, especially truck drivers, face irregular working hours and can be awake for more than 18 hours/day, which reduces their performance and alertness. In this article, we discuss the laws related to Brazilian professional drivers and their current amendments (No. 12,619/2012 and No. 13,103/2015) in relation to working hours at the wheel and rest breaks, which are vital for the quality of life of drivers and society in general. We note that the new law appears to be less efficient than the previous one as it causes insecurity and concern to the users of the transportation system, drivers, and employers. To restrict and reduce accidents, deaths, and injuries in traffic, appropriate legislation is essential, aiming at the safety of workers and users of highways. The law must also benefit the commercial aspect, strengthening the reduction in production and logistics losses. Additionally, traffic education programs are needed, as well as better supervision in relation to total working hours. RESUMO Acidentes de trânsito com consequentes lesões e mortes têm se tornado uma epidemia em nível mundial. No Brasil, a maioria dos motoristas profissionais, sobretudo motoristas de transporte de cargas, enfrenta jornada de trabalho irregular e permanece acordado por mais de 18 horas/dia, o que reduz seu desempenho e estado de alerta. Neste artigo, discutimos as leis dos motoristas profissionais brasileiros e suas alterações vigentes (nº 12.619/2012 e nº 13.103/2015) em relação às horas de trabalho ao volante e a pausas para descanso, imprescindíveis para a qualidade de vida dos motoristas e para a sociedade em geral. Observamos que a nova legislação se mostra menos eficiente que a anterior por causar insegurança e preocupação aos usuários do sistema de transporte, aos próprios motoristas e aos empregadores. Para restringir e reduzir acidentes, mortes e lesões no trânsito, é fundamental uma legislação adequada, que vise à segurança do trabalhador e dos usuários das rodovias. A legislação deve, também, beneficiar o aspecto comercial, que se fortalece pela redução das perdas de produção e logística. Adicionalmente, são necessários programas de educação no trânsito e melhor fiscalização em relação ao tempo total de jornada de trabalho.

RESUMEN

Fundamento: O treinamento resistido promove benefícios à saúde cardiovascular, a qual é influenciada pela privação de sono. Objetivo: Investigar o efeito prévio do treinamento resistido de alta intensidade sobre a contratilidade miocárdica de ratos privados de sono paradoxal. Métodos: Quarenta ratos machos Wistar foram distribuídos nos grupos controle (CTRL), treinamento resistido (TRES), privação de sono paradoxal por 96 horas (PSP96) e treinamento resistido seguido de privação de sono paradoxal por 96 horas (TRES/PSP96). O treinamento resistido foi de alta intensidade, por 8 semanas, 5x/semana. Vinte e quatro horas após a última sessão de treinamento, os grupos PSP96 e TRES/PSP96 foram submetidos ao protocolo de privação de sono paradoxal e em seguida foi realizado o estudo in vitro da mecânica contrátil do músculo papilar isolado. Resultados: Em comparação ao CTRL, os grupos PSP96 e TRES/PSP96 apresentaram menor comprimento do músculo papilar e aumento da área de secção transversa. Associado a essas alterações, verificou-se a diminuição das derivadas temporais da força na contração e relaxamento em todas as condições avaliadas. Somente o grupo PSP96 apresentou redução da tensão de repouso e lentidão no tempo de relaxamento, sendo este último atenuado pelo treinamento resistido prévio. Conclusão: O treinamento resistido prévio à PSP foi parcialmente protetor contra as alterações contráteis do músculo papilar, minimizando a lentidão no tempo de relaxamento. Assim, o caráter de alta intensidade do protocolo adotado parece não proteger plenamente o tecido cardíaco frente a PSP


Background: Resistance training promotes cardiovascular health benefits that may affected by sleep deprivation. Objective: To evaluate the effect of high-intensity resistance training on myocardial contractility in rats subsequently subjected to paradoxical sleep deprivation. Methods: Forty male Wistar rats were distributed into control group (CTRL), resistance training (REST), 96-hour paradoxical sleep deprivation (PSD96) and resistance training followed by 96-hour paradoxical sleep deprivation (REST/PSD96). The animals underwent highintensity resistance training for 8 weeks, 5x/week. Twenty-four hours after the last training session, the PSD96 and REST/PSD96 groups were submitted to paradoxical sleep deprivation, which was followed by the in vitro study of isolated papillary muscle contractile mechanics. Results: In comparison with the CTRL group, a lower papillary muscle length and increased cross sectional area were found in PSD96 and RETS/PSD96, which were associated with decreased temporal parameters of contraction force and relaxation. Decreased resting tension and slowing of relaxation time were found in the PSD96 group only. This effect was attenuated by previous resistance training. Conclusion: Resistance training partially prevented contractile changes induced by PSD, minimizing the slowing in relaxation time. Thus, high-intensity exercise seems to not fully protect the cardiac tissue from PSD-induced effects

RESUMEN

BACKGROUND AND AIM: l-Arginine (l-arg) supplementation and resistance exercise can induce changes in inflammatory and anti-inflammatory cytokines; however, it has not been investigated in obese hypertensive men. This study examines the effects of short-term l-arg supplementation and acute resistance exercise (AREX) on cytokine levels in obese hypertensive men. METHODS: Eight obese hypertensive men aged 46 ± 6 yrs. with an average body weight of 92.56 ± 9.9 kg and a BMI of 31.68 ± 2.18 kg/m2 participated in a randomized, double-blinded, crossover study. The patients were distributed into exercise groups based on the type of supplementation (6 g/day of placebo or l-arg for 7 days). Supplementation periods were separated by a seven-day washout period. The AREX regimen consisted of eight exercises with an exercise intensity of 60% of 1 repetition maximum. The interleukins IL-1ra, IL-6, and IL-10 and the IL-6/IL10 ratio were determined at rest, immediately after exercise and 1 h after exercise sessions. RESULTS: IL-1ra levels exhibited a significant difference both immediately and 1 h after exercise when the l-arg and placebo groups were compared (P < 0.05). IL-6 levels increased significantly after exercise in the placebo group compared with the l-arg group (P < 0.05). The placebo group showed a decrease in the IL-10 levels 1 h after exercise compared with resting levels (P < 0.05). The IL-6/IL-10 ratio showed a statistically significant increase in the placebo group after exercise compared to the l-arg group (P < 0.05). CONCLUSIONS: LARG supplementation attenuates the cytokine increase after AREX, in particular peak IL-6 levels decrease and exercise induced decreases in IL-10 levels are attenuated.

RESUMEN

Objective: To investigate the applicability of predictive equations for resting energy expenditure (REE) in obese individuals with obstructive sleep apnea (OSA) and the effects of OSA severity on REE. Materials and methods: Twenty-nine obese men, 41.5 ± 7 years old, with moderate and severe OSA were recruited. All subjects were submitted to a clinical polysomnography, body composition, and indirect calorimetry measurements. REE was also predicted by three different equations: Harris and Benedict (1919), Cunningham (1990), and DRI (2002). Results: No effects of OSA severity on REE were found. The measured REE (2416.0 ± 447.1 kcal/day) and the REE predicted by equations were different from each other (F = 2713.88; p < 0.05): Harris and Benedict (2128.0 ± 245.8 kcal/day), Cunningham (1789.1 ± 167.8 kcal/day) and DRI (2011.1 ± 181.4 kcal/day). Pearson correlations showed a moderate positive correlation between the REE measured and predicted by all equations. Conclusion: Our findings suggest that predictive equations for REE underestimate the energy expenditure in obese patients with sleep apnea. Also, no effects of OSA severity on REE were found.

RESUMEN

RESUMO O esporte paralímpico cresceu muito nos últimos anos, com isso, torna-se importante a avaliação do sono e da qualidade de vida dos atletas, as quais podem influenciar em seus desempenhos. O objetivo do estudo foi verificar a diferença de percepção de qualidade de sono e de vida entre atletas paralímpicos dois meses antes dos Jogos Paralímpicos de Londres. Foram avaliados 30 atletas com deficiência física (18 atletas) e deficiência visual (12 atletas). Para avaliar a qualidade subjetiva de sono, a sonolência e a qualidade de vida (QV) utilizou-se o questionário de Pittsburgh, a escala de Epworth e o WHOQOL-bref, respectivamente. Para comparação entre grupos de deficiência foi utilizado o teste Mann-Whitney. Para verificar diferenças entre os domínios de QV foi utilizado o teste de Friedman, seguido do teste de Wilcoxon. A associação entre variáveis nominais foi analisada pelo teste qui-quadrado. Houve predomínio de atletas com eficiência de sono >85%. Não houve diferença entre os grupos na comparação da percepção da qualidade de sono. O domínio "meio ambiente" apresentou menor escore comparado a todos os outros domínios, enquanto o domínio "relações sociais" apresentou menor escore comparado ao domínio "psicológico". Não houve diferença na qualidade de sono e QV entre as deficiências.


ABSTRACT Paralympic sport has grown significantly in recent years, andtherefore, is important to evaluate the sleep and the quality of life of these athletes, which can influence their performance. The objective of the study was to verify if there is a difference in perceptions of sleep and quality of life among Paralympic athletes, two months before the London Paralympic Games. A total of30 athletes with physical disability (18 athletes) and visual impairment (12 athletes) were evaluated. The Pittsburgh questionnaire, the Epworth scale and the WHOQOL-bref, respectively, were used to assess subjective sleep quality, somnolence and quality of life (QOL). For comparison between disability groups were used the Mann-Whitney test. To verify differences between the domains of QOL, the Friedman test was used, followed by the Wilcoxon test. The association between nominal variables was analyzed by the Chi-square test. There was a predominance of athletes with sleep efficiency >85%. There was no difference between the groups in the comparison of perception of the quality of sleep. The domain "environment" showed lower scores compared to the other domains, while the domain "social relations" showed lower score compared to the "psychological". There was no difference in the sleep and life between disabilities.

RESUMEN

Abstract BACKGROUND: Physical exercise may contribute to changes in eating behavior. AIMS: to investigate eating behavior and reported energy intake in physically active individuals. METHODS: Thirty-nine healthy adults of both sexes, who were involved in physical fitness training, were enrolled to participate in the study. A food diary and the TFEQ-21 was used for energy intake measurementandeating behaviors identification. RESULTS: All participants showed acceptable levels of all evaluated behaviors: Cognitive restraint (46.58±16.4 and 49.5±20.0), Emotional eating (8.12±12.5 and 40.8±26.7),and Uncontrolled eating (21.6±15.1 and 35.6±20.9) in men and women, respectively. Uncontrolled eating was associated with increased carbohydate intake for women, andfat-free masscontent was associated with less Emotional eating only in men. There were no differences in energy and macronutrient consumption between training and non-training days. CONCLUSION: Regular physical exercise is associateto bettereating behaviors, but women mayfind it harder to maintain or lose weight due to higher levels of emotional eating.
