Heart rate recovery as a sensitive indicator of physical activity changes in perimenopausal and postmenopausal women [PDF]

open access: yesRehabilitacja Medyczna, 2018
Heart rate recovery (HRR), which is defined as the rate of heart rate decline after cessation of exercise, is an important indicator of exercise tolerance.

Estimation of maximal oxygen consumption and heart rate recovery using the Tecumseh sub-maximal step test and their relationship to cardiovascular risk factors [PDF]

open access: yes, 2017
BACKGROUND: Maximum aerobic capacity (VO2max) is associated with lower cardiovascular and total mortality. Step tests can be used to provide an estimate of (VO2max) in epidemiological or home-based studies.

Heart Rate Recovery [PDF]

open access: yesCirculation Research, 2016
In the current issue of Circulation Research , McCrory et al1 report on the association of heart rate recovery after simple orthostatic challenge—otherwise known as standing up—with all-cause mortality. The authors measured heart rate changes in the first 110 seconds after standing up in 4475 participants of an Irish population–based, cohort study ...

Wearing colored glasses can influence the exercise performance and testosterone concentration [PDF]

open access: yes, 2018
Perception of red color is associated with higher testosterone concentration and better human performance. Thus, we evaluated the acute effects of wearing colored-lens glasses on the YoYo intermittent endurance exercise test 2 (YoYoIE2) performance ...

Cardiovascular fitness is associated with child adiposity at 5 years of age: findings from the ROLO longitudinal birth cohort study

open access: yesBMC Pediatrics, 2023
Background Cardiovascular fitness is strongly linked with metabolic risk; however, research is limited in preschool children. Although there is currently no simple validated measure of fitness in preschool children, heart rate recovery has been ...

The G-protein–gated K+ channel, IKACh, is required for regulation of pacemaker activity and recovery of resting heart rate after sympathetic stimulation [PDF]

open access: yes, 2013
Parasympathetic regulation of sinoatrial node (SAN) pacemaker activity modulates multiple ion channels to temper heart rate. The functional role of the G-protein–activated K+ current (IKACh) in the control of SAN pacemaking and heart rate is not ...
