and vice versa31. This influence is most readily apparent in the case of the effect of breathing on heart rate—the increase of heart rate during inspiration and its decrease during expiration
employed to compare the effect of each intervention on the following cardiovascular response indicators before and after intervention: heart rate (HR); heart rate variability (HRV) components; blood volume pulse amplitude (BVPamp); galvanic skin response; respiration rate (RSP); and blood pressure....
1. On increasing the stimulation frequency of isolated pieces of ventricular muscle, the resting potential depolarizes, and the action potential duration and amplitude are reduced. On termination of the high frequency train of action potentials, these changes are reversed. 2. The resting potential ch...

The present study investigated the heart rate (HR) response to various types of physical education (PE) activities for 8- to 9-year-olds (five school classes, n = 93) and the fitness effects of a short-term PE training programme (three of the five classes, n = 59) with high compared...
The purpose of this study was to discuss the effects of stop extracurricular sport training on maximal heart rate of female students and level of their maximal heart rate. Through using the method of Bruce on treadmill, the maximal heart rate of 8 female students was compared around 8 weeks ...
The effects of sound don’t stop with the ears. Nonauditory effects of noise exposure are those effects that don’t cause hearing loss but still can be measured, such as elevated blood pressure, loss of sleep, increased heart rate, cardiovascular constriction, labored breathing, and changes in...
Reduced heart rate (HR) during vagus nerve stimulation (VNS) is associated with therapy for heart failure, but stimulation frequency and amplitude are limited by patient tolerance. An understanding of physiological responses to parameter adjustments would allow differential control of therapeutic and side...
Hypertensives with a high heart rate had the highest risk of stroke and CHD among the Inner Mongolians. These results indicate that the coexistence of hypertension and high heart rate may be a valuable predictor of stroke and CHD incidence. This is a preview of subscription content, access via...
Swimming speeds were generally greater for rainbow trout cultured in the high NO3-N treatment, but were not always significantly different. Although most water quality variables were controlled, significant differences between treatments for the concentrations of other water quality parameters inhibited ...
