This paper presents a novel method for remote heart rate (HR) estimation. Recent studies have proved that blood pumping by the is highly correlated to intense color of face pixels, and surprisingly can be utilized HR Researchers successfully proposed several methods this task, but making it work in realistic situations still challenging problem computer vision community. Furthermore, learning s...

abstractthe borg rating of perceived exertion (rpe) is a way of measuring physicalactivity intensity level. purpose of this study is evaluation of validity and reliability the rpe scale (persian version) based on heart rate variability in students of isfahan university of medicalsciences.methods: an interventional study conducted  on 10 male students, heart rate (hr) and rpe  in two 0-10 and 6-...

OBJECTIVE Our goal was to demonstrate which position would be hemodynamically and technically better by comparing the effects of combined spinal epidural (CSE) in the sitting or lateral decubitus position for elective cesarean deliveries on maternal and neonatal parameters and ephedrine requirement. METHODS Sixty parturients were randomly assigned into two groups to perform CSE in the sitting...

The time course of cardiocirculatory responses to different levels of isometric handgrip (IHG) in sitting position were studied noninvasively in normal males and compared to supine IHG results in the same subjects. Control Comparisons. Resting postural differences were as expected: sitting heart rates (HR), preejection phase (PEP) and PEP/LVET were higher while left ventricular ejection time (L...

BACKGROUND The inactivity physiology paradigm proposes that sedentary behaviors, including sitting too much, are independent of the type of physical activity delineated for health in the Physical Activity Guidelines for Americans. Thus, we hypothesized that, when accounting for behaviors across the entire day, variability in the amount of time spent sitting would be independent of the inter-and...

OBJECTIVES To compare the heart rate responses of women orienteers of different standards and to assess any relation between heart rate responses and age. METHODS Eighteen competitive women orienteers completed the study. They were divided into two groups: eight national standard orienteers (ages 23-67 years); 10 club standard orienteers (ages 24-67 years). Each participant had her heart rate...

Abstract Background N, N-Dimethyltryptamine (N, N-DMT) is a naturally occurring tryptamine-based alkaloid and classic psychedelic. The potent psychoactive properties of N-DMT are mediated by serotonin 2A (5-HT ) receptor agonism. There limited investigations into the physiologic effects inhaled N-DMT, despite this being one most common routes administration. Heart rate variability (HRV) an emer...

Background: To establish a balance between work (physical exercise) and human, the aerobic capacity (VO2max) could be used as a measure. Assessing heart rate in association to physiological symptoms is the most commonly used tools for the assessment of fatigue during physical exercise. This study aimed to investigate the association between the aerobic capacity and the heart rate of workers fro...

During equestrian exercise, communication between riders and horses is very important, riders’ appropriate signals without any disturbance for the horses’ proper movements are required. Therefore, may get different stress depending on rider’s riding balance, posture, proficiency. This study was conducted to confirm difference in of beginner’s expert’s riding, additionally, prove effectiveness b...
