Heart rateBackground: Equations to predict maximum heart rate (HR max) in heart failure (HF) patients receiving β-adrenergic blocking (BB) agents do not consider the cause of HF. We determined equations to predict HR max in patients with ischemic and nonischemic HF receiving BB therapy. ...
We sought to determine a generalized equation for predicting maximal heart rate (HRmax) in healthy adults. BACKGROUND The age-predicted HRmaxequation (i.e., 220 − age) is commonly used as a basis for prescribing exercise programs, as a criterion for achieving maximal exertion and as a clin...
Some matrisome gene expression is modulated by age and associates with age-related histology Aging is a biological process often linked to diseases such as cancer, heart disease, Type II diabetes, and osteoporosis15,16. Aging impacts the matrisome through fibrosis and scarring, a component of whic...
PURPOSE: In the HERITAGE Family Study, heart rate (HR) associated with various percentages of maximal oxygen intake (VO2max) was used to prescribe exercise intensity. When fitness improved, HR at the same power output (PO) decreased, and PO was increased to produce the prescribed HR. Although...
Maximal heart rate (HRmax) declines substantially with age, but the magnitude and possible modifying effect of gender, body composition, and physical activity are not fully established. The present study examined the relationship between HRmax and age in 3320 healthy men and women within a wide age...
Heart Rate-Index Estimates Oxygen Uptake, Energy Expenditure and Aerobic Fitness in Rugby Players The purpose of the study was to verify the suitability of heart rate-index (HRindex) in predicting submaximal oxygen con-sumption (VO2), energy expenditure... AL Colosio,A Pedrinolla,GD Lozzo,.....
A major challenge to human health is that the adult human heart does not regenerate. Myocardial infarction (MI) causes a permanent non-contractile and non-conductive scar, which leads to chronic heart failure and arrhythmia. Much interest has followed the epicardium recently for its key role in ...
(The problem now is as) old as realism —Max Apple Old as stone —Marge Piercy Old as the most ancient of cities and older —Saul Bellow Old women and old men … huddle like misers over their bag of life —Randall Jarrell Some men mellow with age, like wine; but others get still ...
Cardiac output minus heart rate D. End-diastolic volume minus end-systolic volumeIf your blood volume is 5 L, and each beat of your heart pushes out 70 mL of blood and your heart rate of 70 beats per minute, how long does it take for all of your ...
Researchers at the University of Colorado have new insight into the age-old question of why maximum heart rate (maxHR) decreases with age. This decrease in maxHR not only limits the performance of aging athletes but it is also a leading cause for nursing
