abstract = {The attainment of high inter-day reliability is crucial to determine changes in resting
metabolic rate (RMR), respiratory exchange ratio (RER), maximal fat oxidation during exercise
(MFO) and the intensity that elicits MFO (Fatmax) after an intervention. This study aimed to
analyze the inter-day reliability of RMR, RER, MFO and Fatmax in healthy adults using the Ergostik
gas analyzer. Fourteen healthy men (age: 24.4 ± 5.0 years, maximum oxygen uptake (VO2max):
47.5 ± 11.9 mL/kg/min) participated in a repeated-measures study. The study consisted of two
identical experimental trials (Day 1 and Day 2) in which the participants underwent an indirect
calorimetry assessment at resting and during an incremental exercise test. Stoichiometric equations
were used to calculate energy expenditure and substrate oxidation rates. There were no significant
differences when comparing RMR (1999.3 ± 273.9 vs. 1955.7 ± 362.6 kcal/day, p = 0.389), RER
(0.87 ± 0.05 vs. 0.89 ± 0.05, p = 0.143), MFO (0.32 ± 0.20 vs. 0.31 ± 0.20 g/min, p = 0.776) and Fatmax
(45.0 ± 8.6 vs. 46.4 ± 8.4% VO2max, p = 0.435) values in Day 1 vs. Day 2. The inter-day coefficient
of variation for RMR, RER, MFO and Fatmax were 4.85 ± 5.48%, 3.22 ± 3.14%, 7.78 ± 5.51%, and
6.51 ± 8.04%, respectively. In summary, the current results show a good inter-day reliability when
RMR, RER, MFO and Fatmax are determined in healthy men using the Ergostik gas analyzer.},
