Suryanamaskar (SN), a yogic technique is composed of dynamic muscular movements synchronised with deep rhythmic breathing. As it may have influence on CNS, this study planned to investigate immediate effects of SN on reaction time (RT) and heart rate (HR). 21 female volunteers attending yoga classes were recruited for study group and 19 female volunteers not participating in yoga were recruited...

Wrist-worn sensors have better compliance for activity monitoring compared to hip, waist, ankle or chest positions. However, wrist-worn activity monitoring is challenging due to the wide degree of freedom for the hand movements, as well as similarity of hand movements in different activities such as varying intensities of cycling. To strengthen the ability of wrist-worn sensors in detecting hum...

Heart rate (HR) and systolic (SBP), diastolic (DBP) and mean (MBP) blood pressure were recorded by biotelemetry in nine conscious unrestrained sloths for 1 min every 15 min over a 24-h period. The animals were allowed to freely move in an acoustically isolated and temperature-controlled (24 +/- 1 degree C) experimental room with light-dark cycle (12/12 h). Behavior was closely monitored through...

AIMS To evaluate the associations of age at menarche and the leg length-to-sitting-height ratio, markers of adolescent growth, with risk of diabetes in later life. MATERIALS AND METHODS Information from 69,385 women and 55,311 men, aged 40-74 years from the Shanghai Women's Health Study and Shanghai Men's Health Study, were included in the current analyses. Diabetes status was ascertained thr...

Heart rate (HR) is arguably one of the most often measured physiological responses in relation to physical fitness or health. HR measured at rest, during submaximal exercise, at maximal exercise and during recovery can provide some level of assessment of fitness and health. In the past, HR was most often measured from manual palpitation of a pulse (palpation), using a stethoscope (auscultation)...

Prolonged sitting is associated with increased risk for cardiovascular diseases and mortality. However, research into the physiological determinants underlying this relationship is still in its infancy. The aim of the study was to determine the extent to which occupational and leisure-time sitting are associated with nocturnal heart rate variability (HRV) in blue-collar workers. The study inclu...

Background: Age-related increases in arterial stiffness including carotid-femoral pulse wave velocity (cf-PWV), aortic reflection via augmentation index (AIx) and magnitude (RM) have been associated with future cardiovascular event risk. Chronic or prolonged inactivity has reported to exacerbate the age-related stiffness. However, little is known about impact of a short, period on age potential...

The purpose of this study was to monitor heart rate (HR) and rhythm during open water SCUBA dives. Nine children performed 25-min open water SCUBA dives to 8 m depth. Before, during and after these dives, ECG was recorded. Compared with predive heart rate, heart rate declined by -24 ± 8% (range -36%; -15%) during the dive. In some children a further decline in HR was observed within the last mi...

BACKGROUND Higher heart rate has been associated with an adverse prognosis, but most prior studies focused on individuals with known cardiovascular disease or examined a limited number of outcomes. We sought to examine the association of baseline heart rate with both fatal and nonfatal outcomes during 2 decades of follow-up. METHODS AND RESULTS Our study included 4058 Framingham Heart Study p...

Introduction: Resistin, a complex multimeric structure which is secreted by adipose tissue and circulates in the blood, acts on the hypothalamus to increase sympathetic nerve activity, inhibit appetite and is associated with obesity, insulin resistance and cardiovascular disorders. In this study, we survey the cardiovascular effects of direct injection of resistin into specific cell group of th...
