Heart Rate Reserve(HRR): The difference between your maximum and resting heart rate. Heart Rate" on Wikipedia.com. 2] Robergs, R.A., and Landwehr, R. (May 2002), "The Surprising History of the "HRmax=220-age" Equation",Journal of Exercise Physiology onlineVol 5 (2).Read PDF...
Heart rate zones are ranges of beats per minute, based on your heart rate reserve. Heart rate reserve is found by subtracting your resting heart rate from your heart rate maximum: Heart Rate Reserve = Heart Rate Maximum - Resting Heart Rate The ranges of each heart rate zone is a ...
some researchers proposed individual and wearing position calibrations using physiological parameters (such as heart rate, HR) to enhance the reliability and validity of EE estimates28,29. Our previous studies showed that including heart rate reserve (HRR) parameters in the prediction equation can furt...
Participants were randomly assigned to the development group (n=78), whose data were used to calculate the prediction equation, or the validation group (n=48). Results:The HR reserve in this population was significantly lower (0.44卤0.20%) and there was a large discrepancy between conventional ...
11, Pages 5333-5348: Face Validity of the Single Work Ability Item: Comparison with Objectively Measured Heart Rate Reserve over Several Days Purpose: The purpose of this study was to investigate the face validity of the self-reported single item work ability with objectively measured heart rate ...
↑: increased; ↓: decreased; ↔: no change; BP: blood pressure; CO: cardiac output; HR: heart rate; LV: left ventricular; PVR: peripheral vascular resistance; RAAS: renin-angiotensin-aldosterone system; RBC; red blood cell. Blood volume increases considerably during pregnancy, rapidly between...
The simplified Bernoulli equation may occasionally underestimate the RV-RA gradient because of its neglect of the inertial component of the complete Bernoulli equation. Because velocity measurements are angle dependent, it is recommended to gather TR signals from several windows and to use the signal ...
Urine albumin creatinine ratio was determined from first-void urine specimens and estimated glomerular filtration rate was calculated using the Chronic Kidney Disease Epidemiology Collaboration creatinine equation. Post hoc evaluations of change from baseline to week 12 were performed for glycated hemoglobin ...
heart rate leads to an increase in contractility in normal myocardium (positive force-frequency relationship), this relationship is blunted or even negative in failing myocardium. The most commonly used surrogate variables of contractility, such as EF and peak rate of increase of ventricular pressure ...
