The American College of Sports Medicine currently recommends the HR reserve (HRR) method to guide exercise in individuals who have heart failure with reduced ejection fraction. This recommendation is ...
The Mechanoreflex and Hemodynamic Response to Passive Leg Movement in Heart Failure
BLOOD FLOW MECHANORECEPTORS PASSIVE LEG MOVEMENT MUSCLE AFFERENTS
2017/4/13
Background: Sensitization of mechanosensitive afferents, which contribute to the exercise pressor reflex, has been recognized as a characteristic of patients with heart failure (HF); however, the hemo...
Ultra-Short-Term Heart Rate Variability is Sensitive to Training Effects in Team Sports Players
Court sports athletic monitoring cardiac autonomic system futsal
2016/1/9
The aim of this study was to test the possibility of the ultra-short-term lnRMSSD (measured in 1-min post-1-min stabilization period) to detect training induced adaptations in futsal players. Twenty-f...

Low doses caffeine reduce heart rate submaximal cycle ergometry
2015/7/13
The purpose of this study was to examine the cardiovascular effects of two low-levels of caffeine ingestion in non habitual caffeine users at various submaximal and maximal exercise intensities.
Heart Rate Recovery after Submaximal Exercise in Four Different Recovery Protocols in Male Athletes and Non-Athletes
Heart rate recovery autonomic activity active recovery physical activity
2015/5/7
The effects of different recovery protocols on heart rate recovery (HRR) trend through fitted heart rate (HR) decay curves were assessed. Twenty one trained male athletes and 19 sedentary male student...
Accuracy of the Polar S810i Heart Rate Monitor and the Sensewear Pro Armband to Estimate Energy Expenditure of Indoor Rowing Exercise in Overweight and Obese Individuals
Indirect calorimetry armband heart rate monitor energy expenditure indoor rowing
2015/5/5
Accurately assessing the energy expenditure (EE) of different types of physical activity is important for exercise prescription in obese individuals. The aim of this study was to examine the accuracy ...
A Comparison Between Ventilation and Heart Rate as Indicator of Oxygen Uptake During Different Intensities of Exercise
Physical activities light to moderate intensities steady state activities non-steady state activities
2015/5/4
The aim of this study is to compare the relation between ventilation (VE) and oxygen uptake (VO2) [VO2=ƒ(VE)] and between heart rate (HR) and VO2 [VO2=ƒ(HR)]. Each one of the subjects perfor...

Net heart rate physical activity thresholds MET exercise prescription oxygen up-take
2015/4/24
This study had a twofold purpose: i) to develop a regression equation to estimate metabolic equivalent (MET) in walk/run by heart rate increment above rest (NetHR), and; ii) to determine NetHR thresho...
Exercise Limitations in a Competitive Cyclist Twelve Months Post Heart Transplantation
Transplant rehabilitation orthotopic transplant aerobic capacity
2015/4/24
