Resting Metabolic Rate

This prospective observational study aims to characterize within-individual variability in resting metabolic rate (RMR) over a 12-week period using high-frequency repeated measurements under standardized conditions. Participants will undergo RMR assessments three times per week using whole-room indirect calorimetry. The study will quantify the magnitude of physiological variability in RMR, distinguish true biological variation from measurement error, and estimate the minimal detectable change required to identify meaningful metabolic adaptations.

This project is intended to determine the magnitude and duration of RMR changes in patients receiving orthopedic surgery. The result will help to guide postoperative nutrition recommendations in patients receiving orthopedic surgery.

This study examines whether resting metabolic rate (RMR)-the amount of energy the body uses at rest-is similar between biological parents and their adult children (aged 18 years and older). RMR is the largest component of daily energy expenditure and plays an important role in body weight regulation and overall metabolic health. Participants from the same family will undergo a single testing session in a metabolic laboratory. RMR will be measured using indirect calorimetry under standardized conditions, along with body composition assessment and basic health information. The primary goal is to determine whether RMR is correlated within families. The study will also assess whether these similarities remain after accounting for differences in body composition, age, and sex. This observational study will help improve understanding of how metabolism varies between individuals and the extent to which these differences may be influenced by familial or inherited factors. Findings may contribute to future research on personalized nutrition, obesity risk, and metabolic health.

This study aims at investigating the energy expenditure following a single Football trainning session in middle aged males. The participants will perform a soccer training session \[A single training session including 60 minutes of warm up, soccer technical exercises and small-sided game\] and a cotrol trial (No intervention included, only daily measurements) in randomized, repeated measures, crossover design.
