Does caffeine ingestion before a short-term sprint interval training promote body fat loss?

Braz. j. med. biol. res; 52 (12), 2019
We investigated the effect of caffeine ingestion combined with a 2-wk sprint interval training (SIT) on training-induced reductions in body adiposity. Twenty physically-active men ingested either 5 mg/kg of cellulose as a placebo (PLA, n=10) or 5 mg/kg of caffeine (CAF, n=10) 60 min before each SIT sessi...

O metabolismo energético mitocondrial e a síndrome da fadiga crônica: uma scoping review

Nessa dissertação foi realizada uma scoping review com objetivo de buscar na literatura o que existe, até o presente momento, para explicar a relação entre o metabolismo mitocondrial com a síndrome da fadiga crônica (SFC). A SFC se apresenta de forma diferente para cada indivíduo, o que torna com...

Protein and lipid metabolism adjustments in silver catfish (Rhamdia quelen) during different periods of fasting and refeeding

Braz. j. biol; 78 (3), 2018
Abstract The fish may experience periods of food deprivation or starvation which produce metabolic changes. In this study, adult Rhamdia quelen males were subjected to fasting periods of 1, 7, 14, and 21 days and of refeeding 2, 4, 6, and 12 days. The results demonstrated that liver protein was depleted ...

Is willingness to exercise programmed in utero? Reviewing sedentary behavior and the benefits of physical activity in intrauterine growth restricted individuals

J. pediatr. (Rio J.); 94 (6), 2018
Abstract Objective: The literature suggests that a fetus will adapt to surrounding adversities by optimizing its use of energy to improve survival, ultimately leading to the programming of the individual's energy intake and expenditure. While recent reviews focused on the fetal programming of energy int...

Energy expenditure, growth, and nutritional therapy in appropriate and small for gestational age preterm infants

J. pediatr. (Rio J.); 94 (6), 2018
Abstract Objective: To evaluate the resting energy expenditure, growth, and quantity of energy and macronutrients intake in a group of preterm newborns. Methods: The cohort study was performed with appropriate and small for gestational age preterm infants (birth weight lower than 1500 g or gestational ...

Clinical application of thermography for energy balance in athletes - state of the art and new paradigms

Rev. bras. med. esporte; 24 (6), 2018
This article aims to describe the evolution of techniques that have enabled the proper application of the Laws of Thermodynamics for physical activity and athletes. The objective is to propose performance indicators to help add information to the current indices used in medicine and sports, such as the l...

Comparação do gasto energético em diferentes métodos do treinamento de força

Introdução: Atualmente, vem crescendo a utilização de diferentes métodos de treinamento de força (TF) como drop-set e bi-set, com intuito de maximizar gasto energético (GE). Porém, não há evidências que comprovem este fato. Objetivos: Mensurar e comparar o gasto energético (GE) em ses...

Oxygen consumption and energy expenditure during and after street games, active video games and tv

Rev. bras. med. esporte; 24 (5), 2018
INTRODUCTION: Physical activity has become less frequent since the 1980s, even among more active children. OBJECTIVE: To analyze excess post-exercise oxygen consumption (EPOC) and total energy expenditure (TEE) in children during and after three different activities. METHODS: Sixteen healthy children (9....

The dynamics of energy metabolism in the tick embryo

Abstract The cattle tick Rhipicephalus (Boophilus) microplus is an ectoparasite capable of transmitting a large number of pathogens, causing considerable losses in the cattle industry, with substantial damage to livestock. Over the years, important stages of its life cycle, such as the embryo, have been...

Energy supply and demand in the intervertebral disc

Coluna/Columna; 17 (3), 2018
ABSTRACT The intervertebral disc (IVD) is one of the parts of the body most commonly affected by disease, and it is only recently that we have come closer to understanding the reasons for its degeneration, in which nutrient supply plays a crucial role. In this literature review, we discuss the basic prin...
