The impact of high-intensity intermittent exercise on resting metabolic rate in healthy males

The impact of alcohol (ethanol) on resting energy expenditure of male non-obese volunteers was determined in two studies. In the first study the thermic effect of alcohol on resting metabolic rate (RMR) was assessed in ten male non-obese volunteers. In the second study the impact of alcohol on diet-induced thermogenesis (DIT) was determined in twelve male non-obese volunteers. Energy expenditure was measured with a ventilated-hood system. RMR was measured for 60 min with the subjects in a fasting state. In the first study subjects received in random order 20 g alcohol in concentrations of 75, 180 and 300 ml/I water respectively. After measurement of the RMR the thermic effect of alcohol was measured for 90 min. In the second study volunteers received in random order and in duplicate either a meal of food (2 MJ) plus an alcoholic aperitif (20 g alcohol in a 180 ml/1 solution) or an isoenergetic meal of food alone (2.55 MJ) plus a placebo aperitif containing no alcohol. DIT was measured for 240 min. Alcohol induced a significant thermic effect, which varied between 0.22 and 0.30 kJ/min. No systematic difference in DIT was observed among the different concentrations. DIT was not significantly affected by the ingestion of alcohol. Total DIT was 219 (SE 14) kJ for the alcohol treatment and 185 (SE 20) kJ for the control treatment. The results do not support the suggestion that alcohol is less efficiently used as an energy source in comparison with, for example, fats and carbohydrates.

The Impact

Abstract Purpose Low Resting Metabolic Rate (RMR), as a risk factor for obesity, can be affected by many factors. Indeed, genetic and environmental factors are variables taken into account when predicting RMR, and may contribute to a high inter-individual variance. Besides the well-known causes of obesity, researchers have demonstrated the contribution of gut microflora in obesity and energy expenditure. Therefore, the goal of the current study was to compare the Firmicutes/Bacteroidetes ratio and the relative abundance of, Prevotellaceae, Faecalibacterium prausnitzii, bifidobactrium spp, lactobacillus spp, Akkermansia muciniphila, Bacteroides fragilis, and Escherichia coli in two groups of people with normal and low RMR in overweigh/obese women in Iran. Results The abundance of F. prausnitzii (p>0.001), B. fragilis (P= 0.02), and Firmicutes phylum (P= 0.02) were significantly higher in the controls compared to the cases, and showed significant positive association with RMR, (β = 1.29 ×10−5, P=0.01), (β = 4.13 ×10−6, p= 0.04), and (β = 7.76 ×10−1, p= 0.01), respectively. Regarding Lactobacilus, the results showed a significant positive association with RMR (β = 1.73 ×10−4, p= 0.01). Conclusion Intestinal microbiota may be associated with host metabolism. Therefore, future work should investigate, using clinical trials, the impact of manipulating gut microflora to positively influence energy expenditure.

The Impact

The objective of this systematic review was to examine resting metabolic rate (RMR) measured through indirect calorimetry in adults with chronic spinal cord injury (SCI) and to evaluate the predication equations used for the estimation of RMR in this population. The authors additionally aimed to review the impact of sex and level of injury on RMR. A MEDLINE/PubMed, Google Scholar, Scopus, and Web of Science search was performed for studies published from the database inception to January 2018, identifying 326 articles. On the basis of the inclusion criteria, 22 studies remained for review. All articles that were identified were full-text, English language articles examining adults with chronic SCI who were fasted for a minimum of 8 hr before undergoing RMR through indirect calorimetry for at least 20 min. The measured RMR ranged from 1,256.0 to 1,854.0 kcal/day, whereas the estimated RMR ranged from 1,276.8 to 1,808.0 kcal/day in the chronic SCI population. Seven studies overestimated RMR from 4% to 15%, whereas two studies underestimated RMR from 2% to 17% using prediction equations established for the able-bodied population. Two studies produced SCI-specific equations to estimate RMR. With regard to sex and level of injury, RMR does not differ between individuals with tetraplegia and paraplegia, whereas sex-based differences remain inconclusive, given limited results. These data provide evidence for the use of indirect calorimetry to assess RMR and the need to validate SCI-specific prediction equations in the estimation of RMR.
