In the meta-analysis, HRmaxwas strongly related to age (r = −0.90), using the equation of 208 − 0.7 × age. The regression equation obtained in the laboratory-based study (209 − 0.7 × age) was virtually identical to that obtained from the meta-analysis. The regression line was...

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...
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,.....
During maximal exercise, respiratory exchange ratio, rating of perceived exertion, and percent predicted maximal heart rate were similar across age and ethnicity, suggesting equivalent maximum voluntary efforts in all subjects. VO(2 max) (ml x kg(-1) x min(-1)) was inversely related to age (...

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 home admittance for otherwise-healthy ...
Objective To investigate the age-related expression of β3-adrenergic receptor (β3-AR) in rats with experimental heart failure.Methods The model of heart failure was established by banding the aortic diameter.Male Wistar rats were divided into young and aging groups according to age,and each gro...
