Filter by:The purpose of this study is to evaluate the changes in energy expenditure, fat oxidation, reaction time, and perceptual indicators of energy and focus after acute ingestion of a caffeine-based energy drink. Approximately 60 healthy adults aged 18-50 will be recruited for a randomized, double-blind, placebo-controlled study. They will undergo baseline measurements for energy expenditure, fat and carbohydrate oxidation, reaction time, cognition, and perceptual indicators of energy, focus, and concentration. After 28 days, these measurements will be taken again, comparing the effects of a caffeine-based energy drink versus a placebo.
This study was planned to investigate the effect of TRE on the nutritional status and diet quality of individuals and to compare the effects of TRE and energy-restricted diet (ERD) in healthy overweight individuals. The female individuals were randomly divided into the TRE or ERD groups in an unbiased manner using a computer-generated block randomisation list. Individuals in the TRE group applied a diet limited to 8 hours for 8 weeks (16/8). They were fed ad libitum between 10.00 a.m-06.00 p.m and fasted between 06.00 p.m-10.00 a.m.No restrictions were imposed on the type and amount of food consumed during the feeding period. During the fasting period, individuals consumed water and non-energy drinks (tea, coffee, soda, etc.). Individuals in the ERD group followed a diet specially prepared for them for 8 weeks. At the first encounter with individuals, resting energy expenditure (REE) was measured by the indirect calorimetry method. Physical Activity Level (PAL) was determined by physical activity record. The total energy expenditure (TEE) of individuals was determined using the 'REE x PAL' formulation. 'TEE-500 kcal' formulation was used for the diet to be given to individuals. Individuals were not given a diet containing energy below the REE. Acceptable macronutrient distribution range (AMDR) were taken as dietary content. The diet given to individuals has 45-65% carbohydrate, 20-35% fat, 10-35% protein content. Nutritional habits of individuals were taken into consideration while planning the diet. Each individual consumed 3 main meals and the number of snacks was determined individually. Food exchange lists were given to individuals and nutrient changes were explained in detail. Anthropometric and body composition measurements of individuals were taken. The energy expenditure was measured using indirect calorimetry. Blood pressure and heart rate measurements were made. Biochemical parameters were evaluated and food consumption were taken. The quality of dietary intake was assessed using the Healthy Eating Index (HEI) -2015.
This project is feasibility study looking at extreme exercise and possible diet intervention study to counter muscle and weight loss during a 2 person Greenland Ski Traverse in April 2023. By increasing energy intake to above the currently theoretical capacity (2.5 x RMR) the aim is to test a method to find out if there is a maximum to energy intake and whether energy deficit can be minimised; weight loss attenuated, and whether muscle can be preserved. If not, what are the likely adaptive mechanisms and use this to inform future work on dietary interventions

The study evaluates the acute effects of Helichrysum italicum on resting energy expenditure and substrate oxidation in humans. The resting energy expenditure and substrate oxidation will be measured by indirect calorimetry at baseline and after ingestion of either Helichrysum italicum infusion or hot water.
This study is designed to test the effects of the combination of naringenin (from an extract of sweet oranges) and beta carotene on energy expenditure and glucose metabolism in a single human subject.
Background: Pilates is a form of structured physical activity that is commonly used in rehabilitation settings and to improve muscular fitness, balance, and flexibility. Despite its popularity, it is not known whether the energy expenditure (EE) and oxygen consumption from Pilates sessions could also lead to metabolic fitness benefits. The aim of this study was to quantify the intensity and the EE during two different types of Pilates sessions (mat and apparatus). Methods: 18 healthy females (age: 22 ± 3 years; height: 1.6 ± 0.1cm; body mass: 61.0 ± 10.0 kg; body mass index: 21 ± 3 kg/cm2) performed two different sessions. Each session involved the performance of 15 different exercises. Oxygen consumption (VO2) was measured continuously and then converted to EE in Kcal/min. Blood lactate, heart rate (HR), and blood pressure (BP) were also measured. A repeated measures two-way ANOVA (time X group) determined differences between types.
