Infection control of lung function equipment: a practical approach

|

The degree of risk of cross-infection of patients via cardio-pulmonary testing equipment has yet to be quantified.  Based on current evidence, elaborate precautions are not justified, but attention to appropriate routine cleaning and disinfection protocols is important.  The following are recommendations made based on the existing research as summarized in a study published in Respiratory […]

ReeVue Validation and Reliability Study 2015

|

Assessing Resting Metabolic Rate in Overweight and Obese Adolescents With a Portable Indirect Calorimeter: A Pilot Study for Validation and Reliability. Background: Indirect Calorimetry measured via the traditional indirect calorimeter is considered the “gold standard” for determining resting metabolic rate (RMR).  Portable devices for assessing RMR are a less expensive option for measuring RMR in […]

Validation of CardioCoach by Oregon State University

|

This study sought to determine the validity of VO2 peak measurement using the CardioCoach device compared to the Parvo Medics device. The CardioCoach is a much more affordable alternative measurement device. Based on the results, there is statistical evidence to conclude that the two devices produce similar VO2 peak values, meaning that the CardioCoach CO2 […]

Indirect estimation of VO2 Max in athletes by ACSM’s equation: valid or not?

|

Aim: The purpose of this study was to assess the indirect calculation of VO2max using ACSM’s equation for Bruce protocol in athletes of different sports and to compare with the directly measured; secondly to develop regression models predicting VO2 max in athletes. Methods: Fifty five male athletes of national and international level (mean age 28.3 […]

Resting Metabolic Rate Variability as Influenced by Mouthpiece and Noseclip Practice Procedures

|

Breathing through a mouthpiece and noseclip can cause some patients anxiety, which may lead to hyperventilation and influence the results of a resting metabolic rate measurement. This study examines the usefulness of practice as a way to minimize these effects. The conclusion indicates that variability may be reduced when the patient practices breathing through the […]

Validation of the ReeVue and the CardioCoach CO2 for Measuring Resting Energy Expenditure

|

PURPOSE: To examine the validity of the ReeVue™ (RV) and CardioCoachCO2™ (CC) metabolic systems to measure oxygen consumption by comparison to a reference criterion, the MedicalGraphics CardiO2/CP™ (MG). RESULTS: There were no statistical differences between the two MG tests. Therefore, MG VO2 values were averaged and compared to the RV and CC. No significant differences […]

Validation of the CardioCoachCO2 for Submaximal and Maximal Metabolic Exercise Testing

|

This study examined the validity of the CardioCoachCO2 metabolic system to measure oxygen capacity by comparison to a previously validated device. Fourteen subjects (8 men and 6 women; 25.9 6 6.6 years of age) completed 2 maximal graded exercise tests on a cycle ergometer. Subjects were randomly tested on the Cardio- CoachCO2 and Medical Graphics CardiO2/CP (MedGraphics) system on 2 separate visits. […]

Nutrition Care for Patients with Weight Regain after Bariatric Surgery

|

Achieving optimal weight outcomes for patients with obesity is important to the management of their chronic disease. All interventions present risks for weight regain. Bariatric surgery is the most efficacious treatment, producing greater weight losses that are sustained over more time compared to lifestyle interventions. However, approximately 20–30% of patients do not achieve successful weight outcomes, and patients […]

Metabolic Conditioning Among Soccer Players

|

To reduce the risk of overuse injuries, yet obtain optimal fitness development among soccer players, research comparing different training strategies is required. This study compared conventional group conditioning (GRP) to individualized training (IT) during the preseason among female college soccer players. Both groups participated in soccer practices; however, players were randomly assigned to supplemental conditioning differentiated by the use of player-specific heart rate […]

Fat Metabolism During Workout

|

KEY POINTS People store large amounts of body fat in the form of triglycerides within fat (adipose) tissue as well as within muscle fibers (intramuscular triglycerides).When compared to carbohydrate stored as muscle glycogen, these fat stores are mobilized and oxidized at relatively slow rates during exercise. As exercise progresses from low to moderate intensity, e.g., […]
