We integrated GPS and accelerometer data to examine habitat selection and energy expenditure patterns across the diel cycle in Strix varia (Barred Owls), addressing a critical gap in wildlife research that often overlooks activity during the "inactive" phase. Owls in Baton Rouge, Louisiana, selected forests with tall canopies and open understories, particularly in affluent neighborhoods, supporting the "luxury effect" in urban biodiversity. Nocturnal home ranges were larger (31.8 ha) compared to diurnal home ranges (8.9 ha), indicating broader habitat use at night. The total area of preferred nocturnal habitat was 33% of the Baton Rouge study area, whereas preferred diurnal habitat comprised only 5%. Energy expenditure was inversely related to preference in nocturnal home ranges but increased with preference in diurnal home ranges. Our models were validated using independent data from Clemson, South Carolina, supporting the robustness of our analysis and revealing generalities in owl habitat selection across these regions. This research contributes to a deeper understanding of urban ecology, highlighting habitat components preferred by owls and possibly other forest-dwelling species. It emphasizes the difference in nocturnal and diurnal home range sizes, the scarcity of daytime refuges for S. varia in urban landscapes, and the variation in energy expenditure in preferred habitats. Our findings advocate for urban designs that accommodate wildlife activity throughout the day and night, and highlight the positive correlation between preferred owl habitat and affluent neighborhoods, underscoring the need for equitable distribution of green spaces to foster biodiversity across socioeconomic gradients. These insights will help develop strategies to enhance the ecological value of urban environments and the conservation of S. varia and associated forest-dwelling species in rapidly urbanizing areas.

Nutritional habits and anthropometric profiles are directly linked to competitive performance; however, there is a great lack of information on amateur or professional mixed martial arts (MMA) athletes outside the competitive period. The aim of this study was to compare food consumption and anthropometric profile of amateur and professional MMA fighters. The sample was composed of 24 male MMA athletes, middleweight category (age: 27.5 ± 5.0 years; body mass: 79.0 ± 12.1 kg; height: 173.5 ± 0.1 cm; %BF: 19.5 ± 4.0 %, BMI: 26.0 ± 2.8 kg/m2). Food consumption was evaluated based on three 24-hour food diaries using the Multi-Step method in a non-competitive period and analyzed using the Dietbox v2.92 software. The professional group was younger (p = 0.001) than the amateur group. Total energy expenditure was similar between amateur (4364 ± 469 kcal) and professional (4312 ± 381 kcal). Amateur and professional reported an energy deficit between the estimated energy requirement and energy intake. Carbohydrate consumption was below the suggested minimum limits (amateur: 3.3 ± 1.6g/kg/day and professional: 3.3 ± 1.4g/kg/day). Protein intake was within the suggested limits (amateur: 1.4 ± 0.9g/kg/day and professional: 1.8 ± 0.8g/kg/day) and lipids presented borderline values about to with concerning the recommendations in the literature (amateur: 0.9 ± 0.6 / g/kg/day and professional: 1.8 ± 0.9 g/kg/day). Amateur and professional athletes did not differ in terms of food consumption and anthropometric profile. Both groups, amateur and professional, demonstrated negative energy balance and inability to reach the suggested levels of macronutrient intake according to the classification. Thus, it is recommended that both MMA groups receive attention regarding nutritional strategies. [ABSTRACT FROM AUTHOR]

La práctica sistemática de la danza puede contribuir al estado físico de las personas. El objetivo fue determinar la variabilidad fisiológica de tres ritmos autóctonos de danza folklórica nacional en el grupo Yawarkanchik de Cuenca, Ecuador. El estudio fue de tipo descriptivo correlacional, con enfoque cuantitativo y de corte transversal; la intensidad respecto al aumento de la frecuencia cardiaca, distancia, velocidad, números de pasos, el gasto energético y el esfuerzo percibido se analizó con GPS. Participaron 8 bailarines profesionales, 4 mujeres y 4 hombres, con edades entre los 18-30 años. El análisis estadístico se realizó con el programa estadístico SPSS versión 27. Los resultados mostraron que el ritmo de mayor porcentaje de frecuencia cardiaca fue el ritmo de la Sierra con un promedio de 57,64 ±10,30 (p=0.010); respecto a la distancia (p=0.180), la velocidad (p= 0.13) y numero de pasos (p=0.22) se destaca el ritmo del Oriente, seguido el ritmo de la Costa y al final el ritmo de la Sierra, sin diferencias significativas respectivamente. El mayor gasto energético fue el ritmo Sierra 31,62 kcal., seguido del ritmo del Oriente de 28,60 kcal., y el ritmo Costa de 27,29 kcal., con un p=0.000. En cuanto al esfuerzo percibido, el de mayor demanda fue el ritmo de la Sierra con 7.12 ±0,64, el de mediana demanda el ritmo del Oriente con 5.62 ±0,74, y de baja demanda fue el Ritmo de la Costa con 4.25 ±0,46 con un p=1.000.

Background: despite multimillion-dollar investments in sports facilities, there is little information on their contribution to energy expenditure of the population. In this study, participation in 71 physical activities (PAs) and 31 different types of spaces was examined. Objectives: to evaluate which types of spaces are more effective from a public health perspective. Methods: a cross-sectional sample was designed, stratified and proportional to the adult population of Gran Canaria (n = 3,000, ≥ 18 years). PA was evaluated using a validated questionnaire. The spaces used were grouped into two categories: public open spaces and sport facilities. Descriptive statistics and multiple logistic regression were used to analyze the data. Results: the open public spaces accumulated a volume of hours for PA between 1.6 and 28.4 times higher than the sport facilities depending on the socio-demographic group analyzed. The indoor sport facilities were the ones that expressed the greatest associative strength with the achievement of PA recommendations (OR = 5.45, 95 % CI: 4.01; 7.40). Conclusion: a dilemma was posed from a public health perspective because the urban open public spaces reached more population and supported most of the population’s energy expenditure, particularly in the groups with the highest health risk, but the indoor sport facilities were the ones that best contributed to achieving a healthy level of physical activity. This study suggests changes in the polices of construction and management of sport facilities and open public spaces to increase PA in groups at higher health risk. [ABSTRACT FROM AUTHOR]

Montoya Arroyo, J.A., Ramírez Cambronero, J y Aragón Vargas, L.F. (2021). Medición del gasto energético real por usar un producto comercial para ejercitarse en el hogar. PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 19(1 ), 1- 11. La evidencia sobre la importancia de ejercitarse regularmente es abrumadora. Muchas personas, conscientes de ello, recurren a las soluciones simples y atractivas que se les venden por televisión. Lamentablemente, muchos países no tienen reglamentación estricta para valorar las afirmaciones que hacen los productos comerciales; más aún, los requisitos para la evaluación científica de los productos relacionados con el ejercicio parecieran no existir. Cada vez que una persona compra un equipo para ejercitarse y poco después decide renunciar al ejercicio por la falta de resultados positivos, se da un paso hacia atrás en la salud pública. El propósito de este estudio fue medir el gasto energético inducido por utilizar un artículo comercialmente disponible para ejercitarse en casa y contrastarla con su publicidad. Se utilizaron distintos métodos de campo y laboratorio para medir el gasto energético de 27 estudiantes jóvenes, aparentemente saludables (15F, 12M; 19.1 ± 1.0 años; 1.647 ± .073 m; 63.09 ± 10.13 kg; M ± DT) mientras descansaban en posición decúbito supino durante diez minutos y mientras utilizaban la máquina para ejercitarse 10 minutos a intensidad intermedia. Ninguno de los métodos utilizados registró un gasto energético bruto superior a 272 kJ (65 kcal) en 10 min de actividad; el consumo de oxígeno durante el esfuerzo fue equivalente a 1.54 ± .23 MET, que corresponden a 23.4 ± 9.2 kJ (5.6 ± 2.2 kcal) de gasto neto o 70.3 ± 11.7 kJ (16.8 ± 2.8 kcal) de gasto bruto. En contraste, el gasto energético bruto reportado en el comercial del producto es de 277 kcal (1159 kJ) para 10 min. En conclusión, el gasto energético neto real es 1/50 (dos centésimas) del gasto energético presentado en la publicidad

Este estudo objetivou investigar o impacto do cuidado nutricional na melhora da ingestão alimentar (IA) de pacientes internados em uma unidade de emergência. Foram avaliados 49 pacientes admitidos na emergência, onde foi realizado avaliação nutricional (índice de massa corporal e avaliação subjetiva de acordo com idade) e avaliação da IA. Os pacientes com diminuição da IA foram submetidos à intervenção nutricional individualizada por meio da adequação de dieta. Houve predomínio de risco de desnutrição hospitalar pela avaliação subjetiva. Observou-se que a IA reduzida foi causada principalmente pela dificuldade de mastigação e pela diminuição do apetite. Após a intervenção nutricional, verificou-se aumento da aceitação da dieta hospitalar, bem como aumento do valor calórico ingerido. Conclui-se que há um predomínio de risco de desnutrição em pacientes admitidos na unidade de Emergência e que a baixa aceitação alimentar é eminente, sendo que o cuidado nutricional nestes pacientes pode ser uma estratégia simples e efetiva para contornar esta situação.

A la luz de la importancia de la actividad física regular como un elemento clave en la prevención de muchas enfermedades, se reportan a continuación los resultados del estudio realizado con un aparato para ejercitarse en la casa. 22 estudiantes universitarios jóvenes, aparentemente saludables, participaron en el estudio. Se midió el efecto agudo de 10 minutos de ejercicio con el dispositivo sobre la frecuencia cardíaca, el costo energético y la circulación periférica en las piernas. Se contrastan los resultados obtenidos con las afirmaciones que se hacen en distintas versiones de publicidad del aparato en cuestión. No se obtuvieron efectos fisiológicos agudos significativos de la utilización del dispositivo durante 10 minutos continuos: la frecuencia cardíaca aumentó apenas 8 latidos por minuto con respecto al reposo y la temperatura cutánea no varió o más bien disminuyó. El costo energético no fue significativamente mayor mientras se usaba el dispositivo en comparación con la condición de reposo. Estos resultados sugieren que aquellas personas que utilicen este dispositivo en sustitución de la actividad física regular estarán sacrificando beneficios importantes para su salud. Abstract. The importance of doing regular physical activity (exercise) as a key element in the prevention of several diseases is well known. The following experiment was performed to evaluate the acute physiological effects of a home-exercise machine on 22 young, apparently healthy, university students. While the individuals exercised in the machine for ten (10) minutes, measures of heart rate, energy expenditure and peripheral circulation to the legs were taken and recorded. The results were contrasted against the claims made in different ads promoting the selected apparatus. There were no significant acute physiological effects resulting from the utilization of the machine during a 10-minute period. Heart rate increased only 8 beats per minute (bpm) from baseline and the temperature measured on the legs showed no variation or was even reduced. Energy expenditure was not significantly higher while using the device in comparison with the resting condition. These results suggest that consumers using this home-exercise equipment as a substitute of performing regular physical activity will be sacrificing important health benefits.

Objetivo: determinar el gasto energético y el tiempo dedicado a actividad física en condición de vida libre de escolares costarricenses con sobrepeso u obesidad. Metodología: participaron 31 niños y 13 niñas entre 6 y 9 años (7.6 ± 1.03 años) con sobrepeso u obesidad, estado nutricional que se estableció según el IMC. Las variables del estudio fueron la antropometría, el porcentaje de grasa corporal (%GC), el gasto energético total producto de la actividad física a lo largo del día (GEAF total diario), el gasto energético por actividad física (GEAF) y el tiempo dedicado a la actividad física (TAF), las dos últimas se estimaron según condición sedentaria, ligera, moderada o vigorosa, por medio del acelerómetro Actiheart. Resultados: la talla y el %GC fueron significativamente mayores en las niñas (126.8 ± 5.9 cm, 34.0 ± 6.4 %GC) que en los niños (123.0 ± 5.4 cm, 25.2 ± 6.9 %GC). Los niños registraron un GEAF total diario de 824 ± 228.1 kcal/day, GEAF moderada + vigorosa de 285.6 ± 131.7 kcal/day y un TAF moderada + vigorosa de 147.0 ± 66.6 min, valores superiores (p

Durante los últimos años, el concepto de pobreza energética dejó de ser un fenómeno relegado y fue de a poco tomando mayor relevancia, principalmente en los países en vías de desarrollo, ya que es un problema multidimensional que afecta al desarrollo económico y social, disminuyendo los niveles de bienestar, generando externalidades negativas en la productividad, salud, medio ambiente y educación de los miembros de hogar, fundamentalmente en las zonas rurales del país. Por tanto, el presente trabajo de investigación tiene por objetivo principal, analizar la transición energética (periodo 2010-2019) e identificar los principales factores socioeconómicos que influyen en el gasto energético de los hogares en la sierra rural del Perú (periodo 2018-2019). Tomando como muestra 120 582 hogares para el análisis de transición energética y 5 912 hogares para identificar los principales factores socioeconómicos que influyen en el gasto energético, utilizando la metodología de datos de panel. Entre los principales resultados encontrados resalta que; la transición en el uso de combustibles avanzados por parte de los hogares pobres fue menos lenta en comparativa con los hogares no pobres, con una tasa media de crecimiento de 11% y 3% respectivamente, aunque en menor proporción de gasto energético en comparación a los hogares no pobres. Además, se encontró que los principales determinantes socioeconómicos de la pobreza energética medido por el gasto energético son; el ingreso del hogar, el número de habitaciones del hogar y tamaño de hogar, estas resultaron ser positivos y significativos a un nivel de significancia del 5%.

Objetivo: Identificar o comportamento do consumo de oxigênio (VO2), da frequência cardíaca (FC), do gasto energético (GE) e do índice de esforço percebido (IEP) de mulheres jovens durante a realização de dois exercícios sobre o mini trampolim em duas diferentes intensidades. Materiais e Métodos: Doze mulheres jovens (22,5±2,6 anos) praticantes da modalidade Jump participaram do estudo que foi realizado em três sessões: 1) caracterização da amostra e familiarização, 2) teste de esforço máximo, e 3) protocolo experimental. O protocolo experimental foi composto de quatro situações realizadas de forma aleatória: corrida estacionária executada a 125 b.min-1; corrida estacionária executada a 145 b.min-1; polichinelo executado a 125 b.min-1 e polichinelo executado a 145 b.min-1. FC e VO2 foram também expressos em percentual do máximo (%FCmax e %VO2pico, respectivamente) baseado nos dados do teste máximo. Para comparação das variáveis entre os exercícios e entre as cadências foi utilizado o teste de ANOVA de dois fatores para medidas repetidas (α = 5%). Resultados: Os resultados demonstraram efeito significativo da cadência para todas as variáveis analisadas (VO2: p=0,016, %VO2pico: p=0,015, FC: p=0,003, %FCmax: p=0,003, GE: p=0,006 e IEP: p=0,003) e efeito significativo do exercício para a FC (p≤0,001), %FCmax (p≤0,001) e IEP (p=0,003). Além disso, as interações intensidade*exercício foram significativas para as variáveis FC e %FCmax (p=0,002). Conclusão: A intensidade de 145 b.min-1 resultou em valores mais elevados que a intensidade de 125 b.min-1. Além disso, o exercício de corrida estacionária apresentou valores mais elevados que o exercício de polichinelo para as variáveis FC, %FCmax e IEP.

Introducción: La clase de educación física (CEF) debería ser capaz de activar las recomendaciones de ejercicio necesario para para promover un estilo de vida saludable en los niños. Objetivo: Comparar la actividad metabólica, gasto energético, cantidad de ejercicio e intensidad de esfuerzo físico realizado durante una CEF en niños en relación a su estado ponderal. Participantes y Métodos: Un total de 63 niños (8.0 ± 1.4 años) y 57 niñas escolares (8.3 ± 1.6 años) fueron distribuidos en los grupos normopeso (NP), sobrepeso (SP) y obesos (OB) según su índice de masa corporal, y analizados sus desplazamientos corporales con acelerómetros durante una CEF. Resultados: El gasto energético relativo al peso corporal inducido por el ejercicio fue mayor en el grupo NP (4.7 ± 1.8 kcal/kg) respecto al SP (3.4 ± 1.7 kcal/kg) y OB (2.8 ± 1.3 kcal/kg) con P 0.05). Conclusión: Los escolares NP son capaces de gastar más energía en relación a su peso corporal y con una mayor intensidad de ejercicio que sus pares OB durante una CEF. Abstract. Background: The physical education subject (PES) should be capable of activating the exercise recommendations required to promote healthy lifestyle in children. Objective: To compare metabolic activity, energy expenditure, amount of exercise, and intensity of physical effort in children during a PES class, and to relate them to their body mass index. Participants and Methods: A total of 120 schoolchildren (63 boys aged 8.0 ± 1.4 years old; 57 girls aged 8.3 ± 1.6 years old) were grouped in normal weight (NW), overweight (OW), and obese (OB) categories based on their body mass index, and their body movements were measured with accelerometer during a PES class. Results: Energy expenditure related to body weight induced by exercise was higher in the NW group (4.7 ± 1.8 kcal/kg) than in the OW (3.4 ± 1.7 kcal/kg) and OB (2.8 ± 1.3 kcal/kg) groups, with P0.05). Conclusions: NW schoolchildren are able to spend more energy in relation to their body weight and with a greater intensity of exercise than their OB peers during a PES class.

A obesidade é uma doença nutricional muito frequente em cães de meia idade a velhos, sendo considerada uma condição patológica que leva ao acúmulo de gordura corporal. O objetivo deste estudo foi avaliar a condição corporal de cães e identificar o perfil de lipídios séricos e glicose, e analisar essa correspondência com faixa etária, sexo e castração. Foram selecionados 30 cães de ambos os sexos que faziam parte da rotina da Clínica Veterinária Uningá, com anuência dos proprietários. Os cães apresentavam bom estado de saúde e, dentre estes, foram escolhidos 10 cães para o controle, machos (n=5) e fêmeas (n=5), todos inteiros, com ECC ideal (ECC=5), e para o teste, animais machos (n=10) e fêmeas (n=10) castrados com ECC=9, sendo estes considerados obesos. No grupo faixa etária (n=11) com idade de 2 a 7 anos, e maior de 7 anos (n=9). No laboratório de Patologia Clínica da Uningá foram realizados os exames bioquímicos de colesterol, triglicerídeos e glicose. Após jejum alimentar superior a 12 horas, foi feita a coleta de sangue por meio de punção da veia jugular. Para essas análises, foram utilizados kits comerciais (ANALISA). Os dados obtidos foram analisados pelo programa estatístico SAEG (2007) mediante aplicação do teste de Tukey p(

To evaluate the behavior of a molded meat product rich in wheat and soybean flours subjected to different thermal treatments, was the objective of the work. The treatments were: (A) stepped cooking ΔT = 25 °C; (B) cooking at 80 °C; (C) cooking at 95 °C; (D) stepped cooking ΔT = 40 °C and (E) stepped cooking starting at 70 °C. The value of F1070 pasteurization and energy consumption, the texture profile analysis, the firmness in the center, surface of the products and sensory evaluation were evaluated by evaluating the appearance, consistency and flavor attributes. It was concluded that all the treatments studied were stable microbiologically, safe in their conservation and without sensory differences. Variant A turned out to be the hardest with the lowest energy consumption, those staggered at ΔT=40 °C turned out to be longer and the shortest was E with 2.5 h at 95 °C, but with higher energy consumption.

At present, cardiovascular disease (CVD) is the leading cause morbidity and mortality worldwide. Physical activity (PA) has been identified as an invaluable tool for the prevention and treatment of CVD, due to its versatility, relative ease of implementation, and cost-effectivity. The benefits of PA are widely recognized, including improvement of insulin sensitivity, reduction of endothelial dysfunction, and multiple changes in cardiovascular physiology; along with neuroprotective and immunomodulatory effects. Nevertheless, the use of PA as therapeutic tool appears to be limited by deficiencies in health personnel regarding the knowledge and skills required for issuing formal recommendations for PA in clinical practice. This review discusses key concepts such as PA, exercise, and fitness, as well as energy expenditure (EE) and the units used for its measurement. Furthermore, the different options for PA evaluation are also discussed, including subjective methods, which depend on the logging of activities as they occur or retrospectively; and objective methods, which involve the monitoring of biological indicators of EE in real time during the performance of PA. The wide variety of available methods offers enough flexibility to satisfactorily measure PA in any clinical or research scenario. Understanding PA physiology and knowledge of the advantages and disadvantages of each of the assessment methods allows maximum gain from their use, yielding more accurate and beneficial results for patient care. This would allow the optimized use of PA for the prevention and treatment of CVD. [ABSTRACT FROM AUTHOR]

Conforme aumenta la prevalencia de la obesidad en todo el mundo, los investigadores buscan explicaciones para este fenómeno, en particular aquellas relevantes al gasto energético. Se ha identificado que la termogénesis no asociada al ejercicio, abreviada como NEAT(por sus siglas en inglés), es un componente discreto, pero a la vez considerable, del gasto energético diario total. Las exigencias de algunas ocupaciones limitan la disposición de tiempo para la actividad física planificada y claramente reducen la NEAT, lo cual contribuye a las conductas sedentarias que provocan la adiposidad aumentada. Se ha identificado específicamente al tiempo sentado prolongado durante la jornada laboral como un factor de riesgo para la obesidad y las enfermedades crónicas, independientemente de otros factores de riesgo existentes. Se han puesto en práctica algunas estrategias prácticas para aumentar la NEAT durante la jornada laboral: existen estaciones de trabajo que requieren mantener el equilibrio mientras se trabaja sentado en una pelota suiza (bola de ejercicio) o trabajar de pie, también otras en las que se pedalea sentado o se camina en una banda sin fin incorporada al escritorio, para contrarrestar los períodos prolongados de conducta sedentaria en el trabajo. Aunque hay pocos datos sobre los beneficios crónicos de estas estaciones, aquellas que promueven más movimiento—las estaciones de pedaleo o de caminata—aumentan los MET y el gasto energético total más que las otras alternativas. La desventaja de moverse más es que podría haber una disminución en la atención del trabajo de escritorio y, por lo tanto, una disminución en el funcionamiento cognitivo; sin embargo, los datos no son consistentes y puede ser que el beneficio para la salud sea igual o mayor que la desventaja de experimentar algunas pequeñas distracciones durante las tareas de escritorio.

Antecedentes. La inclusión de ejercicio físico supervisado en las intervenciones para el tratamiento de la obesidad infantil es uno de los factores que puede determinar su eficacia. No obstante, aunque las sesiones hayan sido planificadas según las recomendaciones, la respuesta real de los niños/niñas no siempre ha sido cuantificada. La finalidad del trabajo fue analizar el grado de movimiento y estimar el gasto energético durante las sesiones de ejercicio físico de una intervención para el tratamiento de la obesidad infantil. Metodología. Participaron 41 niños/niñas de 8 a 12 años, obesos y poco activos, a los se midió, mediante acelerómetros, el grado de movimiento global y el tiempo dedicado a diferentes niveles de intensidad de esfuerzo (sedentaria, ligera, moderada-vigorosa) y el patrón de las conductas sedentarias y de actividad física durante las sesiones de ejercicio físico de la intervención. Resultados. Las sesiones de 60 minutos de duración, se caracterizan por periodos cortos de moderada-vigorosa intensidad interrumpidos por periodos cortos de menor intensidad de movimiento. Los participantes dedicaron un 58,3% del tiempo a actividades de moderada-vigorosa intensidad, un 30% a actividades de ligera intensidad y solamente un 11.8% del tiempo a conductas sedentarias. Para el conjunto de las sesiones, y en particular a las de fútbol, el gasto energético de los niños fue superior al de las niñas. Conclusiones. El programa de intervención ofrece la oportunidad de aumentar los minutos semanales dedicados a actividad física de moderada y vigorosa intensidad y de incrementar el gasto energético.

Introdução e objetivo: Estudos utilizando acelerômetros em diferentes ambientes tem demonstrado a capacidade desta ferramenta em medir a intensidade das atividades físicas realizadas. Entretanto, ainda permanecem dúvidas quanto à confiabilidade e precisão do aparelho em algumas atividades. Sendo assim, o objetivo deste estudo foi comparar o gasto energético mensurado pela calorimetria indireta e predito pela equação desenvolvida para o acelerômetro Actigraph durante exercício físico contínuo em esteira. Métodos: A amostra foi composta por 13 indivíduos do sexo masculino com idades entre 18 e 35 anos. O protocolo de exercício foi realizado em esteira rolante composto por quatro velocidades: 4 km/h; 6 km/h; 8 km/h e 10 km/h, com duração de 5 minutos cada estágio. As acelerações foram obtidas por meio do acelerômetro modelo Actigraph GT3X. O gasto energético predito foi calculado utilizando-se a equação estabelecida por Freedson et al. Resultados: A correlação entre o gasto avaliado por calorimetria indireta e o gasto predito estimado mediante a acelerometria apresentaram uma correlação positiva forte (r=0,908; p

Introdução: A erva mate tem sido estudada como fator anti-obesidade, principalmente devido ao seu efeito termogênico, entretanto, poucos estudos foram realizados em humanos. Objetivo: Verificar o efeito agudo do consumo da erva mate sobre o gasto energético de indivíduos adultos saudáveis. Métodos: Foram avaliados 9 adultos jovens e saudáveis, do sexo masculino, recrutados voluntariamente a participar do estudo. O estudo foi do tipo cruzado, placebo-controlado e cada indivíduo completou dois experimentos, separados por 7 dias. No primeiro experimento os indivíduos ingeriram placebo (água) e no segundo experimento, erva mate. O placebo foi constituído de 500 ml de água, enquanto que o outro grupo consumiu 5 g de erva mate solúvel, diluídos em 500ml de água. Após 1 hora foi realizado o gasto energético de repouso durante 30 minutos. A avaliação do gasto energético de repouso foi realizada por calorimetria indireta. Resultados: Foi observado que após o consumo do chá mate houve aumento significativo do gasto energético (~125 kcal) (p

O rugby sevens é jogado em um campo com as medidas oficias do rugby-15 e com duração de dois tempos de 7 minutos entre equipes com apenas 7 jogadores cada. Apesar de no sevens três jogadores serem designados como forwards e quatro como backs, esses papéis táticos não são tão claros como no rugby-15. O objetivo foi avaliar e comparar ente as diferentes posições o perfil antropométrico e de performance aeróbia de jogadoras de rugby sevens. Participaram da pesquisa 20 atletas femininas do Vitória Rugby Club (Vitória, ES). As atletas foram agrupadas, em função da sua posição no campo, em forwards (n = 11) e backs (n = 9). Foi realizada uma avaliação antropométrica e uma valiação cardiorrespiratória das atletas. As forwards apresentaram maior massa corporal, maior índice de massa corporal, maior percentual de gordura e maior massa muscular. As backs apresentaram maior consumo máximo de oxigênio (45,3 ± 3,8 mL/kg/min vs 39,7 ± 5,0 mL/kg/min), maior velocidade do consumo máximo do oxigênio e maior intensidade do limiar ventilatório e limiar de compensação respiratória. Concluímos que existem diferenças significativas entre as posições táticas de forwards e backs das jogadoras amadoras de rugby sevens. Todas essas diferenças são explicadas pelas ações específicas realizadas em campo por cada grupo de jogadoras. ABSTRACT Anthropometric and aerobic profile of women rugby seven players: differences between positions The rugby sevens is played on a standard 15-a-side rugby pitch over two 7-minute halves between teams of 7 players; although 3 players are designated as forwards and 4 players as backs, these roles are not as clearly delineated as those in the 15-a-side game. The aim was to evaluate and to compare the anthropometric characteristics and aerobic performance of rugby players between different positions. Twenty female rugby seven players were divided into forwards (n = 11) and backs (n = 9) and undertook anthropometric and endurance testing. The forwards had higher body mass, higher body mass index, higher percentage of fat mass and higher muscle mass. The backs had higher oxygen uptake consumption (45.3 ± 3.8 mL/kg/min vs 39.7 ± 5.0 mL/kg/min), higher velocity of oxygen uptake consumption and higher intensity of ventilatory threshold and respiratory compensation threshold. In conclusion, there are significant differences between the tactical positions of forwards and backs of amauter female rugby seven players. The differences could be explained by the specific actions taken in the field for each group of players.

Introdução e objetivos: O metabolismo basal (Gasto Energético Basal/ GEB) é a energia utilizada por todas as células do organismo humano, para a manutenção do seu funcionamento. O Gasto Energético com Atividades Físicas (GAF), somado ao e ao GEB determinam o GET. Para estimar o GET de indivíduos fisicamente ativos é necessário que se conheça o tipo de exercício praticado, a frequência de treinamentos, duração e intensidade. O presente trabalho teve como objetivo avaliar as diferentes equações para estimativa do GET, comparar os resultados obtidos e apontar as suas possíveis diferenças. Materiais e métodos: Estudo realizado em duas etapas, a primeira parte composta de uma revisão da literatura e a segunda, avaliou-se o GET de dois voluntários adultos (um do gênero masculino e outro do feminino) praticantes de atividade física regular. Resultados: Foram encontradas na literatura cinco equações que estimam o GEB, OMS (1985), FAO/WHO/UNU (1985), Schofield (1985), Mifflin-St Jeor (1990) e Harris Benedict (1919), a partir destas equações, foram realizados os cálculos de GEB, GET e GAF para cada voluntário. Discussão: Ao selecionar uma equação para estimar o GEB e GET o gênero, as variáveis (peso, altura e idade), fator atividade e METs são importantes requisitos para determinar a necessidade energética. Todas as equações apresentaram estimativas mais elevadas para o gênero masculino. O método de Harris-Benedit apresentou uma estimativa do GEB, GET e GEB + MET, maiores do que os outros métodos. Conclusão: Constatou-se que não houve diferenças relevantes entre as equações, portanto todas estão adequadas para serem utilizadas. ABSTRACT Uses of equations and methods to estimate the basal energetic cost and the total energetic cost of adults that practice physical activities: a case study Introduction and Aims: The BEC (Basal Energy Cost / GEB) is the energy used by every cell in the human body for the maintenance of its operation. The Energy Expenditure with Physical Activities (GAF), added to the GEB and determine the GET. To estimate the GET physically active individuals is necessary to know the type of exercise performed, the frequency of training, duration and intensity. This study aimed to evaluate the different equations to estimate the GET, compare the results and point out the possible differences. Methods: A study carried out in two stages, the first part consists of a literature review and the second evaluated the GET two adult volunteers (one male and one female) regularly physically active. Results: We found in the literature five equations that estimate the GEB, WHO (1985), FAO / WHO / UNU (1985), Schofield (1985), Mifflin-St Jeor (1990) and Harris Benedict (1919), from these equations the calculations of GEB, GET and GAF for each volunteer were performed. Discussion: When selecting an equation to estimate the GEB and GET gender, the variables (weight, height and age), factor activity and METs are important requirements to determine the energy requirement. All equations had higher estimates for males. The method of Harris-Benedit gave an estimation of the GEB, GET and REE + MET larger than the other methods. Conclusion: It was found that there were no relevant differences between the equations, so all are suitable for use.

El estudio se propuso con los objetivos de: (1) determinar cambios en valores antropométricos de madres costarricenses y de hijos e hijas en edad preescolar, después de una intervención educativa con material multimedia y (2) determinar diferencias significativas en el gasto energético (GET) de madres de familia al realizar actividad física cotidiana (AFC) y deportiva (AFD) luego del tratamiento. La intervención se aplicó por 8 semanas en 50 familias (madres e infantes preescolares) quienes completaron mediciones antropométricas; además, las madres reportaron sus hábitos de actividad física (AF). Se utilizó un diseño aleatorio de investigación con tres grupos de comparación, estadística de análisis de varianza. No se encontraron interacciones en ninguna de las variables analizadas. Únicamente se encontró diferencia significativa (p≤0.05) en el GET por AFC entre las madres que hacen y no hacen AFD. Las madres que hacen AFD obtuvieron un GET mayor al socializar y realizar tareas del hogar (p=0.038 y p=0.050; respectivamente). En general, las madres realizan 6.93 + 6.505 minutos diarios de AFD que correspondió a un GET de 0.14 + 0.249 METs. El GET por AFC de las madres fue de 39.29 METs diarios. La falta de tiempo y de compromiso fueron las principales limitaciones reportadas para realizar las AF durante el tratamiento. Será importante incluir, en las intervenciones, aspectos sobre modificación de conducta en la familia, específicamente, para crear la adherencia al ejercicio en los padres de familia.

Introduction: proper estimation of energy requirements in children with cerebral palsy (CP) is essential in ensuring that their energy needs are optimally met.Objective: therefore, the purpose of this study was to demonstrate that resting energy expenditure (REE) and total energy expenditure (TEE) are associated with age, anthropometric indicators and body composition in children with spastic cerebral palsy.Methods: a cross-sectional study included 79 participants with spastic CP from 24 months to 16 years nine months. Weight and height (estimated by lower leg length) were obtained; body composition and energy expenditure were estimated by bioelectrical impedance analysis. ANOVA, post hoc tests, the Pearson correlation and determination coefficients (R2) were performed.Results: significant gradual increases according to age in REE and TEE (both in kcal/d) were observed. There were highly significant positive correlations between REE and TEE (kcal/d, kcal/cm/d) with fat-free mass (FFM) and fat mass (FM), but negative correlations between REE (kcal/ kg/d) with body composition and energy indicators. FFM and total body water, and to a lesser extent FM, explained a high percentage of the direct variability of REE and TEE in kcal/d and the inverse in kcal/kg/d.Conclusions: as age increased, energy expenditure also increased. The estimated energy expenditure in kcal/cm/d did not differ with age and sex. The estimated energy expenditure, based on height, would be a practical and reliable method for estimating energy expenditure and ensuring adequate nutritional status. [ABSTRACT FROM AUTHOR]
