Summary of "The heart rate method for estimating oxygen uptake: analyses of reproducibility using a range of heart rates from commuter walking."

The heart rate method, based on the linear relation between heart rate and oxygen uptake, is potentially valuable to monitor intensity levels of physical activities. However, this depends not least on its reproducibility under standard conditions. This study aims, therefore, to evaluate the reproducibility of the heart rate method in the laboratory using a range of heart rates associated with walking commuting.

Impact of β-Blockers on Heart Rate and Oxygen Uptake During Exercise and Recovery in Older Patients With Heart Failure With Preserved Ejection Fraction.

The study aimed to investigate the differences in oxygen uptake (VO2) and heart rate (HR) (at rest, submaximal exercise, peak exercise, and recovery) in patients with heart failure with preserved ejec...

Comparison of creatinine-based methods for estimating glomerular filtration rate in patients with heart failure.

Glomerular filtration rate is an important factor in management of heart failure (HF). Our objective was to validate eight creatinine-based equations for estimating glomerular filtration rate (eGFR) i...

Robust heart-rate estimation from facial videos using Project_ICA.

Remote photoplethysmography (rPPG) can achieve non-contact measurement of heart rate (HR) from a continuous video sequence by scanning the skin surface. However, practical applications are still limit...

Reproducibility of post-exercise heart rate recovery indices: A systematic review.

Heart rate recovery (HRR) has been widely used to evaluate the integrity of the autonomic nervous system with a slower HRR being associated with greater cardiovascular risk. Different HRR indices have...

Investigating the reproducibility of maximal oxygen uptake responses to high-intensity interval training.

To test the hypothesis that observed maximal oxygen uptake (VOmax) and time to fatigue (TTF) responses to two identical periods of standardized high-intensity interval training are reproducible.

Short Term and Day to Day Reproducibility of Reflectometric Measurement of Retinal Oxygen Saturation in Healthy Subjects

Adequate perfusion and oxygenation is essential for the function of the inner retina. Although this is a well known fact, measurement of oxygen saturation in the eye is still a delicate an...

Medical and Biotech [MESH] Definitions

The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.

The rate at which oxygen is used by a tissue; microliters of oxygen STPD used per milligram of tissue per hour; the rate at which oxygen enters the blood from alveolar gas, equal in the steady state to the consumption of oxygen by tissue metabolism throughout the body. (Stedman, 25th ed, p346)

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.

Expenditure of energy during physical activities. Intensity of exertion may be measured by rate of OXYGEN CONSUMPTION; HEAT produced, or HEART RATE. Perceived exertion, a psychological measure of exertion, is included.

The heart rate of the FETUS. The normal range at term is between 120 and 160 beats per minute.
