Filter by:Obesity, as a chronic disease, has emerged as one of the most pressing health concerns in the 21st century. According to statistics, over 2.1 billion individuals worldwide are affected by overweight or obesity. It is worth noting that obesity ranks fifth among the leading causes of mortality globally. Body fat percentage (fat%) serves as an accurate measure for evaluating body fat content, which can be further categorized into subcutaneous fat, intra-abdominal fat, and intra-organ fat. Subcutaneous fat primarily functions in heat preservation and energy storage while intra-abdominal fat plays a crucial role in safeguarding internal organs from harm. Visceral fat deposition mainly occurs due to intracellular lipid degeneration within organ cells. Extensive research has demonstrated significant variations in metabolic indications and risks associated with different types of fats across various body regions. Therefore, precise segmentation and quantification of overall body fat composition and its distribution hold immense significance for studying individual obesity characteristics, predicting health outcomes, facilitating clinical diagnosis, and devising effective treatment strategies. However, it should be noted that current instruments used for measuring body composition exhibit varying levels of accuracy. Henceforth, this study aims to cross-validate several commonly employed body composition analyzers including DXA (Dual-energy X-ray Absorptiometry), BIA (Bioelectrical Impedance Analysis), BODPOD (Air Displacement Plethysmography), MRI (Magnetic Resonance Imaging), deuterium dilution technique, and 3D laser scanning techniques to assess their agreement and discrepancies when measuring different aspects of body composition.
The goal of this clinical trial is to learn if cold water drinking could promote body composition and further extend healthy lifespan in Chinese older adults. The main questions it aims to answer are: 1. Does cold water drinking lower the body fat percentage? 2. Will cold water drinking positively extend lifespan in a long-term Researchers will compare cold water intervention group to a control group (drinking 37℃ water instead) to see if cold water drinking works to promote health and slow down ageing process. Participants will: 1. Drink 4℃ or 37℃ water 4 times (9a.m., 12p.m., 15p.m., 18p.m.) every day for 6 months. 2. Visit the institute and health checkup department for tests and checkup at baseline, the end of the 3rd month, and the end of 6th month.
Study Design and Participants This intervention study was conducted as a randomized controlled trial (RCT) aimed at investigating the effects of time-restricted feeding (TRF) on cardiovascular health markers among overweight male university students in Shenzhen, China. The study recruited male university students aged between 18 and 24 years, with a Body Mass Index (BMI) ranging from 24 to less than 28. All participants were free from severe psychiatric illnesses, metabolic syndrome, diabetes, alcoholic fatty liver disease, hyperthyroidism, or hypothyroidism. Inclusion criteria required participants to be non-smokers, not currently on any diet pills, and have no history of cardiovascular or metabolic diseases. Randomization and Intervention Fifty eligible participants were randomly assigned to either the intervention group (n=25) or the control group (n=25). The intervention group underwent a 6-hour daily TRF from noon to 6 P.M., while the control group did not participate in TRF but maintained their usual eating patterns. No restrictions were placed on the type or quantity of food consumed by participants in either group. Data Collection and Measures Body Composition and Anthropometry: Measurements included body mass index, body fat percentage, muscle mass, hydration levels, protein content, and visceral fat, all assessed using a bioelectrical impedance analysis scale (Mi Body Composition Scale 2 by Huami Technology). Waist circumference was manually measured by experienced nurses using a tape measure. Blood Pressure and Heart Rate: These vital signs were monitored using an arm cuff electronic blood pressure monitor (Panasonic EW3153), with the arm positioned at heart level to ensure accuracy. Measurements were taken after at least five minutes of seated rest. Nutritional Intake Although time-restricted feeding interventions do not usually change the content or quantity of dietary intake, the total daily intakes of energy, fat, protein, carbohydrate, cholesterol, and fibre were calculated using the Nutritionist Pro food analysis program. This was used to determine possible changes in the subjects' dietary composition as a result of the intervention. Compliance and Ethical Considerations The study protocol was approved by the Ethics Committee of the Seventh Affiliated Hospital of Sun Yat-sen University (Shenzhen), with the approval number KY-2022-101-01. All data were handled confidentially, and measures were taken to ensure high adherence and minimal loss to follow-up. Statistical Analysis Descriptive statistics such as range, mean, standard deviation, and percentages were used to describe the sample characteristics. To compare differences, the change from baseline levels was assessed to account for initial variability, employing an independent samples t-test for the analysis.
The aims of this school-based cycling intervention called "ENERGY Commuting to school" (ENERGYCO) will be divided into two phases: Phase I will aim: 1) to design, test, and validate predictive equations for the objective quantification of the energy expenditure related to different modes of commuting to school (i.e., walking, cycling, motorized-vehicle); and 2) to quantify the energy expenditure of each mode of commuting to school using indirect calorimetry in adolescents; and Phase II will aim to evaluate the effect of a school-based cycling intervention on different health-related outcomes, such as energy expenditure, resting metabolic rate, basal metabolism, physical activity levels, body composition, muscle strength, cardiorespiratory fitness, blood pressure, physical literacy, motor competence, and psychosocial outcomes on Spanish adolescents.
This study aims to evaluate the association between body composition and mortality risk among the US population based on data from the National Health and Nutrition Examination Survey (NHANES), a nationally representative cohort.
The purpose of this study is to examine the possible benefits of peanut butter consumption prior to bedtime on sleep and energy levels among fire fighters. Fire fighters require high levels of energy to perform their occupational tasks but commonly lack sleep as well as the amount of dietary protein and fat suggested for tactical athletes. By addressing this gap, we expect that if peanut butter consumption is shown to improve sleep and/or energy, this lifestyle change (peanut butter consumption) may be appealing to fire fighters because of the ease and low cost of peanut butter. Aim 1: Determine if consuming peanut butter prior to bedtime alters measures of sleep quality and quantity in fire fighters. It is hypothesized that firefighters who consume the peanut butter will have positive impacts in measure of sleep quality and energy levels. Aim 2: Examine the effects of peanut butter consumption on morning and evening energy levels
This project is a collaboration between International Atomic Energy Agency (IAEA), FAO Regional Office for Asia and The Pacific, and Mahidol University, Thailand to carry out the study on doubly-labeled water for assessment of total energy expenditure and body composition among infants and young children aged 6-23 months old. Thailand conducted a longitudinal study with participation from 4 other countries, namely, Pakistan, Philippines, Sri Lanka and Vietnam, in undertaking the same assessments in a cross-sectional design.
This study aims to identify sporting talents by profiling a group of young boxers residing in the State of Mexico using unsupervised machine learning methods. This study is supported by Asociación de Boxeo del Estado de México AC (ABEM) and powered by DBSS.
The goal of this randomized control trial is to compare the effect of a liquid formula rich in nutrients and low in calories (supplement) with the progressive diet with conventional foods that we usually recommend in patients after surgery. The main question it aims to answer is if the addition of a high-protein, volume-controlled nutritional supplement as a fundamental part of the diet during the first two months after surgery will preserve the patient's nutritional status and prevent the appearance of nutritional deficits and associated complications. Participants will be evaluated at the beginning, at 1 month and at the end of the study (2m) and the following determinations will be made: - Analytical determination - Nitrogen balance by determining urea N2 in 24-hour urine - Anthropometric determinations - Body composition determined by impedanciometry - Resting energy expenditure and nutrient oxidation measured by indirect calorimetry. - Energy, protein and hydration intake. - Gastrointestinal tolerance through self-registration of symptoms. Researchers will compare the effect of a complete hypocaloric liquid formula group with the usual progressive diet group to see if they achieve the protein intake goal established for patients after obesity surgery, preservation of nutritional status and lean mass during the rapid phase of weight loss and the gastrointestinal tolerance during the first two months after surgery.
In Greece, people of different age groups, including young children to older adults, are involved in traditional dance. To date, the well-know benefits of dancing include entertainment, socialization and increased physical activity. However, the acute effects of Greek traditional dancing on health, physical performance and muscle damage indices remain largely unknown. Therefore, the aim of this project is to evaluate the acute effect of Greek traditional dancing on health-, physical performance-, and muscle damage-related parameters by considering the impact of dancing tempo (slow vs moderate vs fast). In a crossover repeated measures design 10 pre- and 10 post-menopausal women will participate in the three dancing sessions of different tempo in a random order.
