“…This finding is congruent with other studies which have examined the effects of HIT on EPOC and reported small changes in postexercise EE (Chan & Burns 2013;Williams et al 2013;LaForgia et al 1997) but at odds with a recent report which described a large increase in post-exercise EE after an acute bout of continuous moderate intensity cycling (Knab et al 2011). This latter investigation is noteworth gi en the gold standard ethodolog e plo ed.…”

“…Closer scrutiny of the study protocol however reveals one key difference between study methodologies. Notably, in the study conducted by Knab et al (2011) participants were fed back the energy which they expended during exercise (2171 kJ) so that they consumed a much greater amount of food on the exercise trial than their control trial. This extra energy would have significantly augmented resting metabolism (thermic effect of feeding) above that on the control trial and therefore the EPOC that the researchers reported reflects the true increase with exercise plus the increase promoted by a heightened food intake.…”

“…Recently, Knab et al (2011) reported that metabolic rate is augmented for 14 h after a single bout of moderatehigh intensity aerobic exercise, equating to an additional 795 kJ energy expenditure (EE) on top of that expended during exertion. The authors of this previous paper suggest that this excess post-exercise oxygen consumption (EPOC) may significantly contribute to fat loss over the course of exercise training programmes.…”

High intensity intermittent exercise training (HIT) may favourably alter body composition despite low training volumes and predicted energy expenditure (EE). Purpose: to characterise the acute impact of two common HIT protocols on EE and post-exercise oxygen consumption (11 h EPOC). Methods: oxygen consumption (l·min -1 ), respiratory exchange ratio (RER) and EE were measured in nine healthy, lean males over 12 h under three conditions: control (CON), HIT1 (10x one min high intensity cycling bouts followed by one min rest) and HIT2 (10x four min high intensity cycling bouts followed by two min rest). Results: total exercise period EE during HIT1 (1151 ± 205 kJ) (mean ± SD) was significantly lower than HIT2 (2788 ± 322 kJ; p < 0.001). EE within the 60 min after exercise was significantly albeit marginally higher after HIT1 (388 ± 44 kJ; p = 0.02) and HIT2

“…Although differential measurement error is possible, our results suggest that a higher proportion of vigorous physical activity within each category of total physical activity was associated with less adiposity. Given the same energy expenditure, high-intensity exercise may stimulate greater fat oxidation and oxygen consumption during the postexercise period [27,28].…”

“…It is an open-circuit, pull-type, whole-room indirect calorimeter built with walk-in cooler panels [14]. This chamber and the reproducibility of the data generated has been previously described [15]. EE was calculated using an abbreviated Weir's formula (VO 2 X 3.941) + (VCO 2 X 1.106), where VO 2 is the volume of oxygen consumed (L/minute) and VCO 2 is the volume of carbon dioxide released (L/minute).…”

Background: Thermogenic ingredients may play a role in weight management. In vitro and rodent work suggests that components of black pepper may impact energy expenditure, and in humans, other TPRV1 agonists e.g. capsaicin, augment EE. Objectives:To determine the impact of BP on 24-hour EE, respiratory quotient, and biochemical markers of metabolism and satiety, a randomized, controlled, cross-over study of black pepper (0.5mg/meal) versus no pepper control was conducted in post-menopausal women. Subjects spent two 24-hour periods in a whole room indirect calorimeter.Results: Post-meal glucose, insulin, gut peptides and catecholamines were measured. Energy expenditure, respiratory quotient, or biochemical markers assessed did not differ significantly between the black pepper and no pepper control study days. Conclusions:Our findings do not support a role for black pepper in modulating energy expenditure in overweight postmenopausal women. Future work targeting alternative populations, administering black pepper in the fasted state, or in combination with other spices, may reveal the thermogenic effect of this spice. Trial registration: This trial was registered at clinicaltrials.gov (NCT01729143).Key words: Black pepper, piperine, energy expenditure, metabolic chamber Several functional ingredients have been demonstrated to increase energy expenditure (EE) [1]. Of the bioactive spices, the thermogenic and satiating properties of capsaicin, the major pungent principle in hot red pepper (RP), have been studied in some detail [2][3]. Capsaicinmediated activation of the human vanilloid receptor 1 (TRPV1) leading to increased catecholamine secretion and sympathetic nervous system (SNS) activation, is the suggested thermogenic-enhancing mechanism [1]. However, issues surrounding compliance with longerterm capsaicin and hot RP intake in Western populations [4] raises questions about the ingredient's realistic role in weight management.Piperine (1-peperoylpiperidine), the alkaloid contributing to the pungency of black pepper (BP), is also a TRPV1 agonist, and although less potent, showed greater efficacy at TRPV1 than capsaicin [5]. Evidence of increased catecholamine secretion in rats fed piperine [6], represents a plausible mechanism by which piperine may increase EE. Piperine has also been shown to influence gastric emptying and transit time in rodents [7][8] and piperine suppressed adiposity in mice without changing caloric intake [9].Based on this positive cell and animal data, as well as the thermogenic capacity of other TRPV1 agonists, our objective was to test the hypothesis that dietary supplementation with BP would increase 24-hour EE. The study was limited to overweight post-menopausal women, an at risk group in need of targeted dietary guidance.
