Heart Rates of Law Enforcement Officers During Deadly Force Scenarios
… One effect of stress is the increase of the heart rate, Beats per Minute (BPM). Motor skills, peripheral vision and depth perception are affected by an increase in the heart rate. There are advantages to knowing if experience, training, age and Body Mass Index (BMI) have an effect on the …

Comparison of heart rates between deep water running, treadmill running, and cycling
… It has not been well established whether the heart rate (HR) in water exercise and land exercise is the same when the workloads in the water and on land are identical. Using runners and swimmers, this study determined if the HR during treadmill running (TR), cycling, and DWR at 60% and 75% of …

Heart rates in familiar and unfamiliar pairs of young horses and their riders
Heart rate is commonly used variable to measure stress in horses when used together with other variables. Synchronisation of heart rates is commonly used as an indicator of communication and relationship between the horse and the rider. In this experiment were measured differences in heart rates …

Prediction of maximum oxygen uptake from a modified Ymca 3-minute step test
The relationship between post exercise recovery heart rate (PERHR) and maximum oxygen uptake using a height specific bench with a modified Young Men's Christian Association (YMCA) 3-Minute Step Test was investigated. Sixty apparently healthy males and females between the ages of 18 and 55 years …

Validation of the YMCA's guide to setting workloads for the submaximal cycle ergometer test
… a nationally used submaximal test that measures heart rate response to an increasing exercise workload. Two exercise heart rates are used to estimate maximal physical working capacity. A workload guide was established to make testing more efficient. The principle underlying the workload guide was …

The effects of graduated exercise at the piano on the pianist's cardiac output, forearm blood flow, heart rate, and blood pressure
… pianist's cardiac output, forearm blood flow, heart rate, and blood pressure. Also considered were the effects of piano practice conditioning, general cardiovascular conditioning, and acute cigarette smoking on the aforementioned parameters during and after graduated piano exercise. Fifteen …

Activity Levels of Children and Youth: Monitoring Heart Rate Versus Objective Observation
… activity levels when assessed by two methods—heart rates and direct observation. Forty-one participants wore Polar Vantage XL HR Monitors and were videotaped in various situations. Videotape analysis was done using the Children’s Activity Record System (CARS). Heart rates and CARS data were …

Stress: the physiology and psychology of a training situation.
… cortisol values on day 1, had relatively higher heart rates later in the course. Despite variation between the training courses, very similar mean heart rates were recorded in combined and refresher subjects. Relatively elevated heart rates were detected during the HUET brief. This was proposed …

Cardiac slowing as a function of biofeedback and sensory deprivation or biofeedback alone
… (1976) found that subjects required to lower heart rate to avoid the loss of money used the strategy of attending to meaningless stimulation twice as often as subjects required to lower heart rates to obtain money, and that subjects decreasing heart rate to avoid the loss of money performed …

The effects of oestradiol administration on energy metabolism during prolonged exercise in amenorrheic athletes
… other treatment was administered. In all trials heart rates and perceived exertion were monitored, respiratory gases were collected, blood samples were taken from a vein in the antecubital space and analysed for metabolites and hormones. Pre and post exercise muscle biopsies were taken in two …

An energy-efficient hardware system for robust and reliable heart rate monitoring
… real-time, continuous monitoring of the heart rate is needed to detect arrhythmia problems sooner and prevent their severe consequences. To make continuous monitoring possible and give it widespread acceptance, a portable heart rate monitoring system must have three key characteristics: …

Factors limiting the exercise tolerance of patients with end-stage renal failure undergoing maintenance haemodialysis
… Due to their associated anaemia and low peak heart rates during maximal exercise it has been argued that the reduced blood oxygen carrying capacity and central cardiovascular limitations are primarily responsible for the poor exercise tolerance of these patients. However, others suggest that …

Design and development of a low cost heart best monitor device using finger photoplethysmography technique :|bcircuit design and fabrication of a non-invasive heart beat monitoring device that employs reflectance and transmission mode photoplethysmography using parallel port interface and microcontroller PIC16F84A.
A low cost Heart Beat Monitoring device (HBMD) for detecting heart beat in beats per minute is presented in this thesis. An optical technique called “Photoplethysmography” is utilized by attaching to the base of the finger for monitoring beat to beat pulsation. Two major design issues addressed in …
