Heart rate increases linearly with oxygen consumption and therefore exercise intensity. Maximal exercise heart rate is most accurately recorded upon volitional exhaustion and termination of a maximal exercise stress test. Maximal exercise heart rate declines with aging; therefore, several formulae are also...
Resting QT interval was derived from ECG recordings and rate corrected using five formulae (Bazett, Fridericia, Hodges, Framingham, and the nomogram method of Karjalainen). Resting HRV was spectrally decomposed using an autoregressive approach. A negative correlation was detected for QTc interval and ...
The impact of birth weight (BW) on adult health has been studied, related to the autonomic nervous system, and implicated in cardiovascular risk. We investigated cardiorespiratory and heart rate (HR) autonomic recovery after moderate effort in healthy term-born adults with different BWs. We studied...
CO was determined via the Fick method, using the following formula: CO (L/min) = VO2/[1.34 × hemoglobin concentration (Hb) × (SaO2 − SvO2)]. The arterial mixed venous oxygen content difference was calculated as follows: 13.4 × Hb × (SaO2 − ...
The age-predicted maximal heart rate (PMHR) formula, 220--age, is frequently used for identifying exercise training intensity, as well as determining endpo... MH Whaley,LA Kaminsky,GB Dwyer,... - 《Medicine & Science in Sports & Exercise》 被引量: 129发表: 1992年 ...
The resting and exercise heart rate and BP were comparable between patients and control subjects (Table 2).The increase in aortic outflow velocity time integral, peak left ventricular outflow tract velocity, stroke volume, and cardiac output on exercise was significantly higher in control subjects....
Low density lipoprotein-cholesterol (LDL-C) will be determined according to the Friedewald formula estimated by subtracting HDL-C and one fifth of the triglyceride value from the total cholesterol level [81]. Whole blood glycated hemoglobin (HbA1c) will be measured using high performance liquid ...
As Dr. Li notes, the benefits of exercise stem from the increased muscle work, breathing, and heart rate that occurs during activity, rather than the specifictypeof activity. So don’t be afraid to switch things up, whether that means alternating between your favorite activities (cycling, hiki...
(LDL-C) was estimated using the Friedewald formula90. Insulin was measured using the Access Ultrasensitive Insulin Chemiluminescent Immunoassay Kit (Beckman Coulter Inc., Brea, CA, USA). The homeostatic model assessment (HOMA) index was calculated as insulin (µU/mL) x glucose (mmol/L)/22.5...
Slow aerobics was originally developed as a ten-minute programme combining upper limb, lower limb and trunk movements with a low-intensity exercise that does not cause participants’ average heart rate to exceed 110 bpm; this is considered a low-intensity programme for young adults44. Given that...
