A Systematic Review on the Accuracy and Reliability the BodyGem/MedGem Metabolic Devices

2014-07-23 21:28:47 | BioPortfolio


With the number of individuals becoming overweight or obese, healthcare professionals are in need of accurate, reliable, and convenient tools to help personalize weight loss programs. Recently, a new indirect calorimeter (i.e. MedGem / BodyGem; aka “Gem”) was introduced as a convenient solution to determine resting metabolic rate (RMR) for assessment of daily energy needs. Several validation and comparison studies were conducted to determine if the Gem device is accurate and reliable. The purpose of this study was to conduct a systematic review of previous studies that evaluated the accuracy and reliability of the Gem devices.

Resting Metabolic Rate Reliability

This research is being conducted to study the reliability of a method used to measure resting metabolic rate, or how much energy a person expends while at rest.

Resting Metabolic Rate Testing in Bariatric Surgery Patients

This study evaluates if measuring resting metabolic rate (the number of calories the body burns at rest) before surgery can help predict successful weight loss after surgery.

High Intensity Interval Circuit Training on Resting Metabolic Rate in Overweight Adults

This is the first study to examine changes in resting metabolic rate up to 72 hours following an exercise session, and how these changes may be affected by 12 weeks of high intensity inter...

Resting Metabolic Rate is a Predictor of Weight Regain?

he increasing prevalence of obesity in developed countries has also reached Brazil in the last two decades. Conventional treatments are not efficient to sustained weight loss and in some c...

Assessing Dietary Requirements in Relation to Resting Metabolic Rate in Spinal Cord Injury

DHA supplementation decreases resting metabolic rate in healthy young females.

This study examined the independent effects of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acid supplementation on resting metabolic rate (RMR) and substrate oxidation in young healthy females an...

Changes in resting metabolic rate and body composition due to intragastric balloon therapy.

Intragastric balloon (IGB) insertion leads to dietary restriction; however, its neurohormonal actions were also described. Resting metabolic rate (RMR) adjusted for body mass (RMR/mass) seems to incre...

The relationship between resting heart rate and aggression in males is racially variant.

Although resting heart rate is thought to be a generalizable risk factor for aggression, very little research has examined whether this relationship varies by race. We addressed this limitation using ...

The sex- and age-specific association between resting heart rate and hypertension in rural adult residents of Henan province.

To investigate the sex- and age-specific association between resting heart rate and hypertension in rural adult residents of Henan province. At baseline, a total of 20 194 participants were randomly ...

Inter- and intraindividual variability in daily resting heart rate and its associations with age, sex, sleep, BMI, and time of year: Retrospective, longitudinal cohort study of 92,457 adults.

Heart rate is routinely measured as part of the clinical examination but is rarely acted upon unless it is well outside a population-based normal range. With wearable sensor technologies, heart rate c...

Medical and Biotech [MESH] Definitions

A measurement of OXYGEN uptake in a sitting, resting person (resting oxygen consumption), varying with age, sex, race, and other factors. In normal adult men, one MET is approximately 3.5 ml O2/kg/min of body weight. Oxygen uptake during activities or work can be measured in METs which can be use to determine health status and exercise prescription.

Volume of biological fluid completely cleared of drug metabolites as measured in unit time. Elimination occurs as a result of metabolic processes in the kidney, liver, saliva, sweat, intestine, heart, brain, or other site.

A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA.

Hypersecretion of THYROID HORMONES from the THYROID GLAND. Elevated levels of thyroid hormones increase BASAL METABOLIC RATE.

Acquired or inborn metabolic diseases that produce brain dysfunction or damage. These include primary (i.e., disorders intrinsic to the brain) and secondary (i.e., extracranial) metabolic conditions that adversely affect cerebral function.
