Impact of cycling and walking on adiposity and healthcare costs among adults: longitudinal study / Impacto do ciclismo e da caminhada na adiposidade e nos custos de saúde em adultos: estudo longitudinal / Impacto de andar en bicicleta y caminar sobre la adiposidad y los costos de salud en adultos: estudio longitudinal

Abstract: Leisure-time physical activity seems relevant to prevent the development of chronic diseases and obesity. However, not much is known about the economic burden of these healthy behaviors, mainly in longitudinal designs. This study aimed to analyze the impact of walking and cycling on leisure-time on adiposity and healthcare costs among adults. This longitudinal study was conducted at a medium-size Brazilian city and included 198 participants with no missing data attended in the Brazilian Unified National Health System. Cycling and walking were assessed by a questionnaire with a face-to-face interview at four time-points (baseline, 6-month, 12-month, and 18-month). Healthcare costs were assessed using medical records. Adiposity markers included waist circumference and body fatness. Over the follow-up period, participants who were more engaged in cycling presented lower body fatness (p-value = 0.028) and healthcare costs (p-value = 0.038). However, in the multivariate model, the impact of cycling on costs was not significant (p-value = 0.507) due to the impact of number of chronic diseases (p-value = 0.001). Cycling on leisure-time is inversely related to adiposity in adults, whereas its role on preventing chronic diseases seems the main pathway linking it to cost mitigation.

Resumo: A atividade física no lazer parece relevante para prevenir o desenvolvimento de doenças crônicas e obesidade. No entanto, pouco se sabe sobre o impacto econômico destes comportamentos saudáveis, principalmente em estudos longitudinais. O objetivo deste estudo foi analisar o impacto da caminhada e do ciclismo como atividades de lazer na adiposidade e nos custos de saúde em adultos. Este estudo longitudinal foi realizado em uma cidade brasileira de médio porte e incluiu 198 participantes sem dados indisponíveis atendidos no Sistema Único de Saúde brasileiro. A caminhada e o ciclismo foram avaliados por meio de questionário e entrevista presencial em quatro momentos (linha de base, 6 meses, 12 meses e 18 meses). Os custos de saúde foram avaliados por meio de prontuários médicos. Os marcadores de adiposidade incluíram circunferência da cintura e gordura corporal. Durante o período de acompanhamento, os participantes que praticavam mais ciclismo apresentaram menos gordura corporal (p = 0,028) e custos de saúde (p = 0,038). Porém, no modelo multivariado, o impacto do ciclismo nos custos deixou de ser significativo (p = 0,507) devido ao impacto do número de doenças crônicas (p = 0,001). O ciclismo no momento de lazer está inversamente relacionado à adiposidade em adultos, enquanto o seu papel na prevenção de doenças crônicas parece ser o principal aspecto que o liga à redução de custos.

Resumen: La actividad física en el ocio parece relevante para prevenir el desarrollo de enfermedades crónicas y la obesidad. Sin embargo, poco se sabe sobre el impacto económico de estos comportamientos saludables, especialmente en estudios longitudinales. El objetivo de este estudio fue analizar el impacto de caminar y andar en bicicleta como actividades de ocio sobre la adiposidad y los costos de salud en adultos. Este estudio longitudinal se llevó a cabo en una ciudad brasileña de tamaño mediano e incluyó a 198 participantes sin datos indisponibles atendidos en el Sistema Único de Salud brasileño. Se evaluaron los hábitos de caminar y andar en bicicleta mediante un cuestionario y una entrevista cara a cara en cuatro momentos (inicial, 6 meses, 12 meses y 18 meses). Los costos de atención médica se evaluaron utilizando registros médicos. Los marcadores de adiposidad incluyeron la circunferencia de la cintura y la grasa corporal. Durante el período de seguimiento, los participantes que practicaban más ciclismo presentaron menos grasa corporal (p = 0,028) y costos de salud (p = 0,038). Sin embargo, en el modelo multivariado, el impacto del ciclismo en los costos dejó de ser significativo (p = 0,507) debido al impacto del número de enfermedades crónicas (p = 0,001). El hábito de andar en bicicleta en los momentos de ocio está inversamente relacionado con la adiposidad en los adultos, mientras que su papel en la prevención de enfermedades crónicas parece ser el principal aspecto que lo vincula con la reducción de costos.

Introdução: A hérnia discal lombar é o diagnóstico mais comum dentre as alterações degenerativas da coluna lombar. Dentre diversas formas de prevenção e tratamento para hérnia de disco, estão anti-inflamatórios, fisioterapia, acupuntura, antidepressivos, morfina e psicoterapia. O exercício físico pode ser efetivo, de baixo custo e um meio não farmacológico no tratamento. No entanto, existem muitas barreiras para a aceitação no uso específico da atividade física fora do ambiente clínico, como a dança e o esporte. Objetivo: Esse estudo de caso teve como objetivo analisar as contribuições do ballet clássico adaptado para a melhoria do quadro clínico da hérnia de disco lombar. Método: O estudo de caso foi composto por um roteiro feito pelos avaliadores e utilizado em uma mulher com 32 anos de idade, sem experiência na prática do Ballet Clássico. Os exercícios tiveram duração de 13 semanas, realizadas duas vezes por semana (duas horas em cada sessão), totalizando 26 sessões e um total de 52 horas de intervenção. Resultados: Mediante aos laudos médicos de ressonância magnética obtida pós-intervenção, constatou-se que, em relação ao exame anterior, houve redução das dimensões da hérnia discal no nível L4-L5. Já a escala de avaliação de dor visual analógica (EVA) foi de "dor máxima" no período pré intervenção para "sem dor" no pós intervenção. A escala de dor visual numérica (EVN) pré intervenção foi estabelecida em 9 "com dor" e pós intervenção em 2 "sem dor". A escala de dor de facial (EDF) pré intervenção foi estabelecida em fator 6 "com dor" e pós intervenção como fator 2 "sem dor". Conclusão: É possível concluir que após realização do programa de Ballet Clássico adaptado foi possível observar a diminuição dos valores na escala de dor e na dimensão da hérnia de disco da paciente avaliada.

Introduction: A herniated disc in the lower back is the most common diagnosis among degenerative alterations in the lumbar spine. Various forms of treatment for improvement of lumbar disc herniation, such as anti-inflammatories, physical therapy, acupuncture, antidepressants, morphine, and cognitive behavioral therapy. The physical exercise is an effective, inexpensive, and non-pharmacological tool. Although, there are still several barriers to accepting the use of specific physical exercises outside the clinical environment, such as dance and sports. Objective: This study aimed to analyze the contributions of classical ballet adapted to improve the clinical framework of lumbar disc herniation in a beginner student of classical ballet. Method: The case study composed for one script made by the evaluators was applied to an adult woman with 32 years old, who until that point had not practiced classical ballet. The exercises were performed twice a week (two hours for session) for a period of 13 weeks, totaling 26 sessions, giving a total exposure during the intervention of 52 hours. Results: The magnetic image obtained from medical reports after the intervention found that compared to the previous examination the disc herniation at level L4 ­ L5 was reduced in size. In addition, the visual analog pain scale (EVA) assessment pre intervention was maximum pain and post intervention was no pain. The numeric pain scale rating (NPS) pre intervention was number 9 with pain, and post intervention, number 2 painless. The Faces Pain Scales (FPS) pre intervention had a factor of 6 with pain, and post-intervention factor 2, painless. Conclusion: It is possible to conclude that the present script made by the evaluators was sufficient for cause the of herniation reduction in the evaluated patient post intervention.

Effects of concurrent training and intermittent fasting on structural, functional, and morphological parameters of the heart / Efectos del entrenamiento concurrente y el ayuno intermitente sobre los parámetros estructurales, funcionales y morfológicos del corazón

SUMMARY: Intermittent fasting and concurrent training have been performed frequently to decrease body mass. The aim was to analyze the effects of concurrent training (CT) and intermittent fasting (IF) on cardiac remodeling. In total, 39 adult male Wistar rats were used, divided into four groups: control (C [n = 12]), fasting control (FC [n = 11]), training (T [n = 8]) and fasting training (FT [n = 8]). The CT protocol was composed of 12 sessions, with 30 minutes of aerobic training (AT) in the liquid medium at an intensity of 80 % of the anaerobic threshold, followed by resistance training (RT) with 4 series of 10 aquatic jumps at an corresponding to 50 % of body weight. The IF period was established at 12/12 hours, starting at 9 p.m. and ending at 9 a.m. Echocardiographic analyzes were performed before and after the intervention and, at the end of the experiment, samples of the cardiac tissue were collected to perform the histological analyses. Data analysis was performed using the Shapiro-Wilk tests, Analysis of Variance - ANOVA with Tukey's post-test, and Kruskal- Wallis with Dunn's post-test. All procedures assumed an error of 5 % (p<0.05). Neither group showed alterations in the functional (min. p= 0.12 - max. p= 0.83) and structural parameters of the heart (min. p=0.31 - max. p=0.83). A decrease was observed in the area of cardiomyocytes in the T (p=0.001) and FT groups (p=0.001). The CT and IF did not alter the functional and structural parameters of the heart, but did cause a decrease in the area of the cardiomyocytes.

RESUMEN: El ayuno intermitente y el entrenamiento concurrente se han realizado frecuentemente para disminuir la masa corporal. El objetivo fue analizar los efectos del entrenamiento concurrente (EC) y el ayuno intermitente (AI) sobre el remodelado cardíaco. En total, se utilizaron 39 ratas Wistar macho adultas, divididas en cuatro grupos: control (C [n = 12]), control en ayunas (AC [n = 11]), entrenamiento (E [n = 8]) y ayuno, entrenamiento [n = 8]). El protocolo de EC estuvo compuesto de 12 sesiones, con 30 minutos de entrenamiento aeróbico (EA) en el medio líquido a una intensidad del 80 % del umbral anaeróbico, seguido de entrenamiento de resistencia (ER) con 4 series de 10 saltos acuáticos correspondiente al 50 % del peso corporal. El período de AI se estableció a las 12/12 horas, a partir de las 21:00 horas. finalizando a las 9 a.m. Se realizaron análisis ecocardiográficos antes y después de la intervención y, al finalizar el experimento, se reco- lectaron muestras del tejido cardíaco para realizar los análisis histológicos. El análisis de los datos se realizó mediante las pruebas de Shapiro-Wilk, Análisis de Varianza - ANOVA con pos test de Tukey y Kruskal-Wallis con postest de Dunn. Todos los procedimientos asumieron un error del 5 % (p <0,05). No se observaron alteraciones funcionales de los grupos (mín. P = 0,12 - máx. P = 0,83) y estructurales del corazón (mín. P = 0,31 - máx. P = 0,83). Se observó una disminución en el área de cardiomiocitos en los grupos E (p = 0,001) y EA (p = 0,001). La EC y la AI no alteraron los parámetros funcionales y estructurales del corazón, pero sí provocaron una disminución del área de los cardiomiocitos.

Chronic low back pain and physical activity among patients within the Brazilian National Health System: a cross-sectional study

BACKGROUND: This study was based on filling a gap in our knowledge regarding the issue of what the protective effect of physical exercise on patients within the Brazilian National Health System could be, in relation to low back pain. OBJECTIVES: To determine the prevalence of chronic low back pain (CLBP) and to analyze the protective effect of physical exercise among patients over 50 years old attended at primary healthcare units (PHUs). DESIGN AND SETTING: Analytical cross-sectional study at Universidade Estadual Paulista (UNESP) that was conducted in two PHUs (Parque Cedral and Vila Real), located in different regions of the city of Presidente Prudente, Brazil. METHODS: In total, 327 patients were interviewed and evaluated at which retrospective characteristics covering the previous 12 months. The Nordic questionnaire was used to classify CLBP, and the Baecke questionnaire for physical activity level. The body mass index (kg/m2) was calculated using body mass and height values, both collected at the time of the interview. RESULTS: High prevalence of low back pain was found; 175 patients (53.5%) reported having had at least one episode of low back pain in the previous year. Of these, 71 (21.7%) answered yes to all four questions on the Nordic questionnaire and were classified as CLBP. Physical exercise remained associated with CLBP, independent of other factors (odds ratio = 0.35; 95% confidence interval = 0.15-0.80). CONCLUSION: High prevalence of low back pain was identified among PHU users. Physical exercise was associated as an independent protective factor against this pathological condition.

Effect of growth hormone (GH) and resistance training on the collagen properties of femoral bone tissue / Efecto de la hormona de crecimiento (HC) y el entrenamiento de fuerza en las propiedades colágenas del tejido óseo femoral

The indiscriminate use of anabolic steroids in gyms has been growing in a generalized way, among which, the most common is growth hormone (GH). In the short term GH may potentiate muscle growth, especially when taken in combination with resistance training. However, the effects of this hormone are not yet fully understood in the literature, especially in relation to collagen properties. The objective of this study was to evaluate the effect of the application of growth hormone (GH) and resistance training (RT) on the collagen properties of femoral bone tissue using Raman Spectroscopy. In this study 40 male rats were randomly distributed into four groups (n=10): control (C), control and GH application (GH), resistance training (T), and resistance training and GH application (GHT). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50 % of body weight and duration of four weeks. GH was applied at a dosage of 0.2 IU/Kg (0.067 mg/kg) to each animal, three times a week, every other day. The animals were euthanized and the right femurs were collected for analysis of bone structure. Raman spectroscopy (RS) was used to observe the following compounds from their respective bands: type I collagen (662 cm-1), amide III (1243 cm-1), proteins including type I collagen (1278 cm-1), woven collagen (1322 cm-1), association of collagen, phospholipids, nucleic acid, and phosphate (1330 cm-1), and collagen and protein deformation (1448 cm-1). The results demonstrated an increase in the collagen properties in all analyzed variables, however, the T group presented a statistically significant difference (p<0.05). It is possible to conclude that isolated physical training was shown to be more efficient than when combined with the application of GH to increase the collagen properties of the femoral bone tissue.

El uso indiscriminado de anabolizantes en los gimnasios ha aumentado de forma generalizada, entre éstos la hormona de crecimiento (HC) es una de las más utilizadas, y a corto plazo puede potencializar el crecimiento muscular, principalmente cuando es realizado en combinación con el entrenamiento de fuerza. Sin embargo, los efectos de esta hormona aún no están totalmente esclarecidos en la literatura, especialmente en relación a las propiedades colágenas. El objetivo del estudio fue evaluar el efecto de la aplicación del HC y entrenamiento de fuerza (E) en las propiedades colágenas del tejido óseo femoral a partir de la utilización de la espectroscopía Raman. Se usaron 40 ratas Wistar distribuidos en cuatro grupos (n=10): control (C), control y aplicación del HC (HCC), entrenamiento de fuerza (E) y entrenamiento de fuerza y aplicación del HC (THC). El entrenamiento fue compuesto por cuatro series de 10 saltos acuáticos, realizados tres veces por semana, con sobrecarga correspondiente a 50 % del peso corporal y duración de cuatro semanas. El HC fue aplicado en una dosificación de 0,2 UI/Kg (0,067 mg/kg) en cada animal, tres veces por semana, en días no consecutivos. Los animales fueran eutanasiados y se retiró el fémur derecho para realización del análisis de la estructura ósea. La espectroscopía Raman (ER) fue utilizada para observar los siguientes compuestos a partir de las respectivas bandas: colágeno tipo I (662 cm-1), amida III (1243 cm1), proteínas, incluido colágeno tipo I (1278 cm-1), colágeno retorcido (1322 cm-1), asociación de colágeno, fosfolípidos, ácidos nucleicos y fosfato (1330 cm-1), deformación de colágeno y proteína (1448 cm-1). Hubo aumento en las propiedades colágenas en todas las variables analizadas, sin embargo, solamente el grupo E demostró una diferencia estadísticamente significativa (p<0,05). En conclusión, para el aumento de las propiedades colágenas del tejido óseo femoral, el entrenamiento físico aislado es más eficiente que el entrenamiento combinado con el uso de HC.

Effects of consumption of soft drinks on the muscular morphology of animals submitted to concurrent training / Efecto del consumo de bebidas refrescantes en la morfología muscular de animales sometidos a entrenamiento concurrente

The consumption of industrialized foods and beverages contributes to the increase in body weight and manifestation of diverse illnesses. Among these industrialized products, soft drinks can be mentioned, which when consumed in large quantities can contribute to weight gain and the emergence of chronic non-communicable diseases such as hypertension, diabetes, and obesity. In terms of performance, several training protocols have been used, among which concurrent training is presented as a tool that can aid in the control of body weight and muscle development. Thus, the identification of dietary factors, as well as the use of appropriate training methods, can be essential factors in the increase in physical performance. To study the effects of concurrent training on the skeletal muscles of animals submitted to soft drink consumption. In the present study, 32 male rats were used, of the Wistar breed, in the post-weaning biological phase (30 days). The animals performed a concurrent training protocol. Forty-eight hours after the final training session, the animals were submitted to a surgical procedure to remove samples of gastrocnemius muscle. After preparation of the histological slides, the muscle fibers of the different groups of animals were measured. The median values for the minimum diameter of muscle fibers presented the following values: Control (C): 35.78, Control Soft Drinks (CSD): 36.93, Training (T): 39.12, and Training Soft Drinks (TSD): 37.82. The CSD and TSD groups demonstrated the greatest increase in body mass in relation to the C and T groups. In addition, the groups that performed the concurrent training presented a higher mean of the smallest fiber diameter. It was concluded that the ingestion of soft drinks had a negative effect on the muscular hypertrophy of animals submitted to a concurrent training protocol.

El consumo de alimentos y bebidas industrializadas contribuyen al aumento de peso corporal y manifestación de diversas enfermedades. Entre estos alimentos, se encuentran las bebidas refrescantes, que al ser consumidas en grandes proporciones, pueden contribuir al aumento de peso y a la aparición de enfermedades crónicas, tales como la hipertensión, diabetes y obesidad. En cuanto al desempeño, diversos protocolos han sido utilizados, entre estos, el entrenamiento concurrente que puede ser una forma de ayuda en el control de peso corporal y el desarrollo muscular. Siendo así, la identificación de los factores alimentarios, como también la utilización de los métodos correctos de entrenamiento, pueden ser esenciales en el aumento del desempeño físico. El objetivo del estudio fue investigar los efectos del entrenamiento concurrente en la musculatura esquelética de animales sometidos al consumo de bebidas refrescantes. En la presente investigación fueran utilizadas 32 ratas Wistar. Los animales fueran sometidos a un protocolo de entrenamiento concurrente. Después de 48 horas de la última sesión de entrenamiento, los animales fueran sometidos a un proceso quirúrgico para la remoción de muestras de tejido muscular. Los valores de la media del diámetro de las fibras musculares fueron: Control (C): 35,78; Control y Bebida Refrescante (CBR): 36,93; Entrenamiento (ET): 39,12; y Entrenamiento y Bebida Refrescante (EBR): 37,82. Se observó que los grupos CBR y EBR presentaron mayor aumento de masa corporal en comparación con C y T. Además, los grupos que realizaran el entrenamiento concurrente obtuvieron una mayor media en el diámetro de las fibras. Es posible concluir que el consumo de bebidas refrescantes tiene una influencia negativa en la hipertrofia muscular de animales sometidos a un protocolo de entrenamiento concurrente.

Muscle strength training is better than the use of growth hormone (GH) in bone health of Wistar rats / Entrenamiento de la fuerza muscular es mejor que el uso de la hormona del crecimiento (GH) en salud ósea del ratas Wistar

SUMMARY: The objective of this study was to evaluate the effects of growth hormone (GH) and muscle strength training (ST) on the composition of bone tissue of Wistar rats through Raman spectroscopy. In total, 40 male rats were randomly distributed into four groups: (N = 10) control (C), control with the application of GH (GHC), strength training (T), and strength training with the application of GH (GHT). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50 % of body weight and duration of four weeks. GH was applied at a dose of 0.2 IU / kg in each animal three times a week and every other day. After four weeks, the animals were euthanized and the right femurs collected for analysis of the bone structure. Raman spectroscopy (ER) was used to observe the following compounds from their respective bands: Calcium Carbonate-Triglycerides (fatty acids) 1073 cm-1, Collagen type I 509 cm-1, Bone-DNA Phosphate (Protein) 589 cm-1, Phosphate Phospholipids 1078 cm-1. For the statistical analysis, the Shapiro-Wilk and ANOVA One-Way variance analysis normality tests were performed, followed by the Tukey post-test. The results showed an increase in the concentrations of calcium carbonate-triglycerides (fatty acids), type I collagen, bone phosphate-DNA (protein), and phosphate phospholipids in all experimental groups, with or without ST and/or GH , But only the isolated training group differed significantly from the control group (P <0.05). It was concluded that all treatments could promote bone tissue gain, however, only the T group demonstrated a significant difference in the mineral compounds analyzed.

RESUMEN: El objetivo del estudio fue avaluar el efecto de la aplicación de la hormona del crecimiento (GH) y entrenamiento de la fuerza muscular (EF) en la composición del tejido óseo de ratas Wistar a partir de la espectroscopía Raman. Fueron utilizadas 40 ratas machos distribuidas de forma aleatoria en cuatro grupos (n=10): control (C), control y aplicación de GH (GHC), entrenamiento de la fuerza muscular (EF) y entrenamiento de la fuerza muscular y aplicación del GH (GHE). El entrenamiento fue consistió en cuatro series de 10 saltos acuáticos, realizados tres veces en la semana, con sobrecarga correspondiente a 50 % de la masa corporal y durante cuatro semanas. El GH fue aplicado en la dosificación de 0,2 UI/kg en cada animal, tres veces en la semana y en días alternados. Después de cuatro semanas, los animales fueran eutanasiados y retirados los fémures derechos para un análisis de la estructura ósea. La espectroscopía Raman fue utilizada para observar los siguientes compuestos a partir de las respectivas bandas: Carbonato de Calcio-Triglicéridos (ácidos grasos) 1073 cm-1, Colágeno Tipo I 509 cm-1, Fosfato Óseo-DNA (Proteína) 589 cm1, Fosfato Fosfolípidos 1078 cm-1. Para el análisis estadístico, fueron realizadas las pruebas Shapiro-Wilk y el análisis de variancia ANOVA One-Way, seguida de test post hoc de Tukey. Los resultados revelaran aumento de la concentración de Carbonato de Calcio-Triglicéridos (ácidos grasos), Colágeno Tipo I, Fosfato Óseo- DNA (Proteína), Fosfato Fosfolípidos en todos los grupos experimentales, asociados o no a la realización del EF y/o aplicación del GH. Además, solamente el grupo EF mostró diferencia significativa del grupo C (p<0,05). Es posible concluir que todos los tratamientos mostraran aumentos en el tejido óseo, sin embargo, solamente el grupo T demostró una diferencia significativa en los compuestos minerales analizados.

Can participation in sports during childhood influence physical activity in adulthood?

Abstract Aims: The promotion of sports participation during the early years of life is important not only because it promotes health during childhood and adolescence, but also because it has benefits in adulthood. This study was developed to identify the association between sports participation during the early years of life and adulthood, to analyze the non-participation in sports throughout life and to identify the correlates of non-participation in sports. DESIGN: Cross-sectional study. Methods: The sample was composed of 743 adults randomly selected in a medium-size Brazilian city. Non-participation in sports during childhood and adolescence was assessed through specific questions, and non-participation in sports in adulthood was assessed using the second section of Baecke questionnaire. Answering "no" in the three periods assessed (childhood, adolescence and adulthood) was characterized as non-participation in sports throughout life. Chronological age, sex, formal education, BMI, current job and ethnicity were considered covariates. Categorical data were expressed as rates and compared using chi-square test and binary logistic regression. Results: The prevalence of adults not engaged in sports throughout life was 58.5% (95% CI= 55.1 - 62.1). Females (OR = 2.41 [1.71 - 3.38]), those more advanced in age (OR = 3.29 [1.82-5.94]) and/or possessing a lower level of education (OR = 4.47 [2.45 - 8.17]) were associated with the non-engagement in sports. Conclusion: Non-participation in sports during childhood can influence non-participation in sports during adulthood, which is significantly affected by sex, age and education level.

Association between sleep disorders and chronic diseases in patients of the brazilian national health system / Associação entre distúrbios do sono e doenças crônicas em pacientes do sistema único de saúde

ABSTRACT Many factors are associated with sleep disorders, causing an increase in health spending. The objective of this study was to analyze the association of sleep disorders and non-communicablechronic diseases in patients over 50 years of age, attended by Basic Health Care Units of Presidente Prudente. In total, 363 patients participated. The history of diseases was self-reported through the use of a questionnaire, the level of physical activity was evaluated by the Baecke questionnaire, and sleep quality was assessed using the Mini-Sleep Questionnaire. Anthropometric and body composition data were collected using a stadiometer and scale; patients in the highest (75th) percentile were considered obese. Statistical analysis was performed using the Student t test, chi-square test, and binary logistic regression. The results showed that sleep disorders are associated with osteoporosis, arthritis/osteoarthritis, low back pain, depression, and obesity. Additionally, obesity and physical inactivity influence the occurrence of non-communicable chronic diseases.

Efeito das cargas de treinamento sobre parâmetros fisiológicos de futebolistas / Effect of training loads on physiological parameters of soccer players

O objetivo desse estudo foi verificar os efeitos de três semanas de treinamentos com intensidades monitoradas sobre a capacidade aeróbia de futebolistas profissionais. Quatorze futebolistas integrantes de equipe da primeira divisão do Campeonato Brasileiro de 2010, foram avaliados pré e pós três semanas de treinamento. O limiar anaeróbio (LAn) foi determinado pelo método bi-segmentado, para isso quatro esforços submáximos de 800 metros com intensidades de 10, 12, 14 e 16 km/h foram aplicados. Trinta três sessões de treinamentos foram quantificadas em zonas de acordo com frequência cardíaca referente ao LAn (FC LAn): Z1 - 10% abaixo, Z2 - 90-100% e Z3 - acima da FC LAn. Durante os treinamentos os jogadores permaneceram 31,17±14,86%, 42,96±14,90% e 25,87±16,67% em Z1, Z2 e Z3, respectivamente. Não foram encontradas diferenças significativas no LAn (pré = 13,29 ± 0,71 km∙h-1; pós=12,85 ± 0,90 km∙h-1), percepção subjetiva de esforço correspondente ao LAn (pré = 11,53 ± 1,45 u.a; pós=11,23 ± 1,53 u.a) e FC LAn (pré = 166,64 ± 10,69 bpm; pós = 174,50 ± 10,89 bpm), indicando que três semanas de treinamento são insuficiente para gerar adaptações positivas no LAn de futebolistas.

The aim of this study was to investigate the effects of three weeks of training with intensity monitored on the aerobic capacity of professional soccer players. Fourteen players, members of a first division Brazilian Championship team in 2010, aged 22.78 ± 3.06 years were evaluated pre and post three weeks of training. The anaerobic threshold intensity LAn was determined by bi-segmented method, for this four submaximal efforts of 800 meters with intensities 10, 12, 14 and 16 km/h were applied. Thirty three training sessions were quantified in zones according to heart rate related to the LAn (FC LAn): Z1 - 10% below, Z2 - 90-100% and Z3 - above the FC LAn. During training participants remained 31.17 ± 14.86%, 42.96% and 25.87 ± 14.90 ± 16.67% in Z1, Z2, and Z3 respectively. There were no significant differences in the LAn (pre = 13,29 ± 0,71 km∙h-1; post = 12,85 ± 0,90 km∙h-1), perceived exertion (pre = 11,53 ± 1,45 u.a; post = 11,23 ± 1,53 u.a) and FC LAn (pre = 166,64 ± 10,69 bpm; post = 174,50 ± 10,89 bpm) between conditions before and after training, indicating that three weeks of training are insufficient to generate positive changes in soccer players LAn.

Análise epidemiológica de lesões e perfil físico de atletas do futebol amador na região do oeste paulista / Epidemiological assessment of injuries and physical profile of amateur soccer players in the western region of São Paulo

INTRODUÇÃO: O conhecimento do perfil físico ideal para cada função e das lesões que mais acometem cada atleta é essencial para o sucesso de uma equipe. Este estudo teve dois objetivos: (a) definir o perfil físico dos atletas e (b) estudar epidemiologicamente as lesões sofridas, durante a Copa Municipal de Futebol Amador. METODOLOGIA: Foram avaliados 50 atletas divididos em cinco grupos: goleiros (GO), zagueiros (ZA), laterais (LA), meio-campistas (MC) e atacantes (AT). As lesões foram classificadas, pelo local, mecanismo, gravidade e posição do jogador. RESULTADOS: O perfil físico dos atletas foi: altura de 1,74 ± 0,07m, peso de 74,93 ± 8,17kg, percentual de gordura de 15,19 ± 3,03 por cento, flexibilidade de 27,56 ± 12,0cm e idade de 25,32 ± 4,41 anos. A análise realizada revelou diferenças significativas entre as variáveis altura (p < 0,001) e peso (p = 0,021) em relação à posição dos atletas em campo, e correlação entre incidência de lesões e diminuição da flexibilidade. Foram registradas 21 lesões em 53 partidas, correspondendo a 0,40 lesões por jogo, ou 12 lesões por 1.000 horas/atleta. As lesões com contato físico representaram 57 por cento; nove lesões (43 por cento) foram classificadas como leves e apenas cinco (24 por cento) foram consideradas graves. CONCLUSÃO: O perfil físico dos atletas avaliados foi similar ao anteriormente referenciado, homogêneo nas variáveis percentual de gordura corpórea, flexibilidade e idade; houve diferença estatística significativa na altura e peso, a incidência de lesões foi menor do que em estudos prévios, o local acometido, a circunstância em que ocorreram, e a correlação com a flexibilidade foi coerente com a literatura.

INTRODUCTION: The knowledge on the ideal physical profile for each task, and on the injuries which mostly happen to each athlete, is essential to any successful team. This study had two aims: (a) to define the athletes' physical profile and (b) to epidemiologically study the injuries suffered during the Municipal Amateur Soccer Cup. METHODOLOGY: 50 athletes divided in five groups were assessed: goalkeepers (GO); fullbacks (FB); sideways (SW); midfielders (MF); forwards (FO). The injuries were classified by area, mechanism, severity and player's position. RESULTS: The physical profile of the athletes was: 5'21'' ± 2.75'' height, 165.08 ± 1.79 lb weight, 15.19 ± 3.03 percent body fat percentage, 27.56 ± 12.0 cm flexibility and age of 25.32 ± 4.41. The analysis held revealed significant differences between height (p < 0.001) and weight (p = 0.021) related to the athlete's position on the field, and correlation between injury occurrence and flexibility decrease. 21 injuries were recorded in 53 games, corresponding to 0.40 injuries/game, or 12 injuries/1,000 hours/athlete. Contact injuries represented 57 percent; nine injuries (43 percent) were light, and only five (24 percent) were considered severe. CONCLUSION: the athletes' physical profile assessed was similar to the previous reference and homogeneous in the body fat percentage, flexibility and age variables. Significant statistical difference was observed in height and weight; injury occurrence was lower than in previous studies; the area, situation in which they occurred and correlation with flexibility were in agreement with the literature.
