The BFMNU method as an alternative to the methods in use based on energy: study of the correlation between food energy and body mass
2018
Abstract Introduction: to establish slimming guidelines and any other changing treatments is useful to know the individual's energy expenditure due to the fact that, nowadays, the incidence of many diseases related to the loss of lean mass and the accumulation of adipose tissue has increased. The dietary treatments are carried out on calculating the energy contained in food, and then put in relation to the total energy expended by the body in order to produce changes in body mass. Objective: the aim of this study was to evaluate the correlation between the food energy and body mass of different subjects in various pathophysiological conditions. Methods: one hundred and twenty subjects (male…
Energy expenditure during an ultraendurance alpine climbing race.
2009
Accurate reports of energy expenditure (EE) during prolonged mountaineering activity are sparse. The purpose of this study was to estimate EE during a winter ultraendurance climbing race and individual mountaineering activities in Mont Blanc, France.Seven days before the race, resting metabolic rate (RMR) and maximal oxygen consumption (Vo2(max)) were measured in 10 experienced male climbers (30.0 +/- 0.9 years). Three days before (reference period) and during the race, heart rate (HR) was recorded for estimation of total daily EE (TDEE), and the type and duration of all activities were collected through questionnaires. Total DEE was calculated by adding DEE during sleep (DEE sleep), sedent…
Diet high in protein-rich foods with structured sport activity may be useless to lose fat mass and maintain fat-free mass
2020
Background The aim of this study was to demonstrate that a normal protein diet along with minimal sports activity can be enough to lose fat mass and maintain muscle mass. Methods All participants were prescribed a hypocaloric nutritionally balanced Mediterranean-style diet tailored to the individual for 8 weeks. Body composition and energy expenditure were measured. Sedentary patients (G1) were only recommended to perform minimal aerobic training, while sport subjects (G2) were prescribed structured physical activity and higher calorie and protein contents in the diet. Results There were no significant differences between the two groups for any of the measured parameters. Conclusions The mo…
Within-Day Energy Deficiency and Metabolic Perturbation in Male Endurance Athletes.
2018
Endurance athletes are at increased risk of relative energy deficiency associated with metabolic perturbation and impaired health. We aimed to estimate and compare within-day energy balance in male athletes with suppressed and normal resting metabolic rate (RMR) and explore whether within-day energy deficiency is associated with endocrine markers of energy deficiency. A total of 31 male cyclists, triathletes, and long-distance runners recruited from regional competitive sports clubs were included. The protocol comprised measurements of RMR by ventilated hood and energy intake and energy expenditure to predict RMRratio (measured RMR/predicted RMR), energy availability, 24-hr energy balance a…
A new method to calculate external mechanical work using force-platform data in ecological situations in humans: Application to Parkinson's disease
2016
Abstract Background and aim To accurately quantify the cost of physical activity and to evaluate the different components of energy expenditure in humans, it is necessary to evaluate external mechanical work ( W EXT ). Large platform systems surpass other currently used techniques. Here, we describe a calculation method for force-platforms to calculate long-term W EXT . Methods Each force-platform (2.46 × 1.60 m and 3.80 × 2.48 m) rests on 4 piezoelectric sensors. During long periods of recording, a drift in the speed of displacement of the center of mass (necessary to calculate W EXT ) is generated. To suppress this drift, wavelet decomposition is used to low-pass filter the source signal.…
Improved Nutritional Knowledge in the Obese Adult Population Modifies Eating Habits and Serum and Anthropometric Markers
2020
Multicomponent lifestyle interventions achieve good results in the management of obesity among the adult population. However, their implementation in certain populations poses difficulties. A good level of nutritional knowledge enables people to make changes in their diet that improve their health. This study aims to assess the relationship between nutritional knowledge and nutritional parameters such as dietary intake, anthropometric parameters and biomarkers. A before&ndash
Resting metabolic rate and postabsorptive substrate oxidation in morbidly obese subjects before and after massive weight loss
1996
OBJECTIVE: To investigate the changes of resting metabolic rate (RMR) and postabsorptive oxidation of carbohydrates (CHO), lipids (LIP) and proteins (PT) in morbidly obese subjects after long-term stable massive weight reduction. DESIGN: Longitudinal, intervention study of a bilio-pancreatic by-pass. SUBJECTS: Ten (Four men, six women) obese subjects (BMI: 53.7 ± 2.1 kg/m2, men, nine women) control subjects (BMI: 21.4 ± 1.0 kg/m2). MEASUREMENTS: RMR and substrates oxidation (indirect calorimetry), body composition (bioelectrical impedance), plasma concentrations of glucose, FFA, insulin and thyroid hormones before (T0, prior to surgery), during (T1: 1-3 months, and T2: 9-16 months following…
High-Intensity Interval Resistance Training (HIRT) influences resting energy expenditure and respiratory ratio in non-dieting individuals
2012
Abstract Background The benefits of exercise are well established but one major barrier for many is time. It has been proposed that short period resistance training (RT) could play a role in weight control by increasing resting energy expenditure (REE) but the effects of different kinds of RT has not been widely reported. Methods We tested the acute effects of high-intensity interval resistance training (HIRT) vs. traditional resistance training (TT) on REE and respiratory ratio (RR) at 22 hours post-exercise. In two separate sessions, seventeen trained males carried out HIRT and TT protocols. The HIRT technique consists of: 6 repetitions, 20 seconds rest, 2/3 repetitions, 20 secs rest, 2/3…
Significant reduction of physical activity in patients with neuromuscular disease during COVID-19 pandemic: the long-term consequences of quarantine
2020
Abstract Background Quarantine was the measure taken by governments to control the rapid spread of COVID-19. This restriction resulted in a sudden change in people’s lifestyle, leading to an increase in sedentary behavior and a related decrease in the practice of physical activity (PA). However, in neuromuscular diseases patients need to perform regular PA to counteract the negative consequences of the disease. Hence, the aim of this study was to estimate the levels of PA, measured as energy expenditure (MET–minute/week), among patients with neuromuscular disease (NMD) before and during the last week of quarantine. Methods A total of 268 Italian subjects, living in Sicily, completed an adap…
Basal metabolic rate in narcoleptic patients.
2009
PATIENTS SUFFERING FROM NARCOLEPSY TEND TO BE OBESE.1,2 AMONG OTHER HYPOTHESES LOWER RESTING ENERGY EXPENDITURE HAS BEEN SUSPECTED to be the cause of the narcolepsy-associated obesity.3,4 The use of indirect calorimetry is a well-established noninvasive method to measure the energy expenditure (EE) and the resting (basal) metabolic rate (BMR). Chabas et al. recently published an evaluation of eating behavior and energy balance of 7 typical and 6 atypical narcoleptic patients and 9 controls using indirect calorimetry. Narcoleptic patients were found to have a lower energy expenditure (EE) than controls (n = 13, P = 0.07). Thus, it was concluded that narcolepsy associated obesity could be the…
