El objetivo de esta revisión fue analizar los estudios que investigaron los efectos del ejercicio aeróbico y de fuerza sobre la tasa metabólica en reposo como medios para el control del sobrepeso y de la obesidad. Se realizó una búsqueda electrónica en las principales bases de datos y se revisaron las citas de los artículos identificados en la búsqueda electrónica. Los efectos crónicos del entrenamiento aeróbico sobre la tasa metabólica en reposo parecen limitados; sin embargo, parece que la combinación de volumen e intensidad de ejercicio junto con el tiempo de entrenamiento produce efectos agudos sobre la misma. El entrenamiento de fuerza está asociado al incremento de masa muscular que puede generar un incremento de la tasa metabólica en reposo a largo plazo. Son necesarios más estudios para evaluar la asociación del entrenamiento de la fuerza y entrenamiento aeróbico, así como su impacto sobre la tasa metabólica en reposo, tanto de forma aguda como crónica. ABSTRACT The objective of this review was to analyze the studies that investigated about the effects of aerobic and strength exercise in resting metabolic rate as a means to control overweight and obesity. The main electronic databases were used to search for articles and it were reviewed the references of the main articles identified in the electronic search. The chronic effects of aerobic training on resting metabolic rate appear limited; however, it seems that the combination of volume and intensity of exercise and duration of training produces acute effects on it. Strength training is associated with an increase in muscle mass that can lead to a chronic increase in resting metabolic rate. More studies are needed to evaluate the association of aerobic training and strength training, and its impact on resting metabolic rate, both acutely and chronically. RESUMO O objetivo desta revisão foi analisar os estudos que investigaram os efeitos do exercício aeróbico e de força na taxa metabólica de repouso com aplicações no controle do sobrepeso e obesidade. As fontes utilizadas para localizar os artigos foram: busca eletrônica nas principais bases de dados e citações em artigos identificados na busca eletrônica. Os resultados obtidos sobre a taxa metabólica de repouso decorrente do treinamento aeróbico de forma crônica são limitados, porém, existem indícios que a combinação de volume e intensidade do exercício e tempo de treinamento podem produzir efeito agudo na mesma. Já o treinamento de força normalmente produz um aumento da massa muscular e com possibilidade de gerar um aumento na taxa metabólica de repouso a longo prazo. São necessários mais estudos para avaliar a associação do treinamento de força e aeróbico e seu impacto sobre a taxa metabólica de repouso, tanto de forma aguda como crônica.

Background: Over 50% of adults in Latin America and the Caribbean have a body mass index (BMI) ≥ 25 suggesting excess energy intakes relative to energy expenditure. Accurate estimation of resting metabolic rate (RMR), the largest component of total energy requirements, is crucial to strategies aimed at reducing the prevalence and incidence of overweight and obesity. Aim: We evaluated the accuracies of established and locally developed RMR prediction equations (RMRP) among adults. Methods: Four hundred adult volunteers ages 20 to 65 years had RMR measured (RMRM) with a MedGem® indirect calorimeter according to recommended procedures. RMRP were compared to RMRM with values ± 10% of RMRM deemed accurate. Anthropometry was measured using standard procedure. Linear regression with bootstrap analyses was used to develop local RMRP equations based on anthropometric and demographic variables. The University of the West Indies Ethics Committee approved the study. Results: Males had higher mean absolute RMR ( p < 0.001) but similar mean age-adjusted measured RMR per kg of body (20.9 vs. 21.5 kcals/day; p = 0.1) to females. The top performing established anthropometry-based RMRP among participants by sex, physical activity (PA) level and BMI status subgroups were Mifflin-St Jeor, Owen, Korth, Harris–Benedict, and Livingston, while Johnstone, Cunningham, Müller (body composition (BC)), Katch and McArdle, Mifflin-St Jeor (BC) were the most accurate BC-based RMRP. Locally developed RMRP had accuracies comparable to their top-ranked established RMRP counterparts. Conclusions: Accuracies of established RMRP depended on habitual PA level, BMI status, BC and sex. Furthermore, locally developed RMRP provide useful alternatives to established RMRP.

Abstract Background: Previous studies have shown that the minor allele (C allele) for Cry 1 rs2287161, may be associated with increased risk of cardiovascular diseases (CVDs). Low resting metabolic rate (RMR) caused by the diet has been shown to have, potentially, unfavorable effects on obesity. This study sought to investigate the interactions between the Cry 1 Gene and fat intake on RMR in overweight and obese women.Methods: This comparative cross-sectional study was conducted on 377 Iranian women with overweight and obesity. A food frequency questionnaire (FFQ), with 147 items, was used to assess dietary intake. Individuals were categorized into two groups based on the rs2287161 genotype. Body composition, dietary intake, and RMR were assessed for all participants.Results: There was a significant difference between genotypes for FBS (P=0.04), fat free mass (FFM) (P=0.0009), RMR per FFM (P =0.05), RMR per body mass index (BMI) (P=0.02), and RMR deviation (P=0.01). Our findings also showed significant interactions between total fat and C allele carrier group on RMR per kg, RMR per body surface area (BSA), RMR per FFM, and RMR deviation (P for interaction <0.1), in addition to a significant interaction between CC+CG group genotype and PUFA intake on RMR per BMI (P for interaction =0.009) and RMR per kg (P for interaction=0.02) and RMR per BSA (P=0.07), compared to the GG group, after control for confounder factors.Conclusion: These results highlight that dietary compositions, gene variants, and their interaction, should be acutely considered in lower RMR.

AbstractW e compared the effects of 16-week-training on rest metabolic rate, aerobic power, and body fat, and the post-exercise effects upon rest oxygen uptake and respiratory exchange ratio in overweight middle-aged females. Twenty nine overweight women (BMI 29.9 ± 1.2 kg*m-²) participated in training (3 days a week). The subjects were divided onto groups of aerobic (AT) and strength (ST) training. The results showed that the total body mass decrease and VO2 max increase did not differ in both groups. Decrease in waist circumference after 16 weeks was higher in the ST group. In the ST group fat-free mass increased during the first 8 weeks. Rest metabolic rate was increased significantly at 16th week compared to initial value in ST group only. Significant increase in post-exercise resting VO2 and respiratory exchange ratio at 12 and 36 h was observed after the strength training session only. Increase in rest metabolic rate and post-exercise rest energy expenditure occurred after strength training but not after aerobic training despite the similar increase in aerobic power. The effect of 8-16 weeks of strength training on body mass decrease was higher in comparison to aerobic training.
