Introduction: We humans can perform the same tasks with different efficiency under different conditions. E.g. a basketball player’s performance ability differs each game. His ability to shoot basket after basket and his scoring differs each night. Through this model we would like to measure the efficiency with which he plays. When humans are challenged or pressured, their physiology responds in a stressful manner. The heart rate increases and becomes unstable, constantly fluctuating in a manner where the good decision making ability becomes compromised. This is the basic idea behind this project. We want to evaluate and come up with quantitative values on how efficiently a person is performing under pressure compared with their full natural abilities.
Heart rate measurement is an electrical signal; it has an average mean which is the heart beat rate (HBR) and variance which is the heart rate variability (HRV: Heart rate variability is the amount of heart rate fluctuations around the mean rate. It is an important informative tool to investigate the sympathetic and parasympathetic function of the autonomic nervous system.

Humans always try to improve their performance to get the best results (ref fig 2). Results can be any kind of results related to academic, relationship, sport, etc. Performance of an individual depends on its behavior. Behavior basically means do things differently. Thinking is basically the factor that influences the behavior of a person. The way an individual thinks automatically reflects on the behavior. Thinking is the awareness of thoughts in our mind. The factor that influences thinking is feeling. Think...

Arduino is an open source electronics prototyping platform. It connects to the computer with a standard USB/ Serial cable. Arduino board is used to compute and process the pulse signal received from the IR pulse sensor and to calculate the heart rate variability. Arduino has its own programming environment and language.
Processing is an open source programming language and integrated development environment (IDE) built for Visualization. In this project we are using ‘Processing IDE’ to display signals after processing the data and to plot the HRV graph.
With the help of the above mentioned hardware’s and software’s we aim to Quantitative model for human physiological response to pressurized environment
It determines how well your heart pumps with each beat by measuring the percentage of blood leaving your heart
In this article, it tells how an EKG scan is on grid paper and each small block, which is one millimeter (mm) long, represents 0.04 seconds and each larger box, which is five millimeters long, represents 0.2 seconds. On a EKG scan, the voltage of the heart is measured in millivolts (mV) along the y-axis. On the scan grid, ten millimeters is equal to one millivolt. According to this source, in order to calculate the beats per minute (BPM), one divides the number of number of large boxes between each heart beat (QRS wave) in 300 small boxes. However, that used for a more consistent and steady heart rate. For a more varied and irregular rhythm, one has to count the number of QRS waves in six seconds and then multiply that number by ten. For an example, if there are eight QRS waves, then the estimated heart rate would be 80
The first participant measured her pulse rate for 30 seconds before starting the exercise. Her pulse rate was calculated to determine the number of beats per minute. She then stepped on the platform (up and down) and continued at a slow pace for 3 minutes. After three minutes of the exercise, she measured her pulse rate every minute to determine her recovery time. This process was repeated until her pulse rate returned to normal.
The heart is an extraordinary structure that is the base of all human life. However, it similar to the uncomplicated functions of water pumps. As the heart beats, blood is distributed throughout the body using a network of blood vessels. The functions of the heart can be kept in regular and healthy conditions through exercise. Exercise has an effect on the blood that is circulating through the body. That circulating blood makes the heart desire more oxygen, causing the heart rate to increase rapidly to keep up with activity demand.
The main components of the human cardiovascular system include the heart and blood vessels. The heart beats in order to pump blood to the vessels which are responsible for circulating it to cell tissue throughout the body. During the homeostasis process, the circulatory system provides oxygen and nutrients to the cell while removing waste products from the tissue fluid such as carbon dioxide within the lungs. This process is required for cell function.
The idea of thoughts as they connect to behaviors can be traced back to Epictetus (55 AD -135 AD , Greek Stoic and Philosopher). He stated, “Men are not disturbed by things, but by the view which they take of them (Epictetus and Higgonson, 1944). Epictetus also wrote, “Do not strive for things occurring to occur as you wish, but wish things occurring as they occur, and you will flow well (Epictetus and Lebell, 1994).” In other words, see things for what they really are and good health will follow (Romaneck, 2007).” Another belief was that a sage or teacher was immune to unhappiness and misf...
The purpose of this experiment was to gather data on how the amount of time spent active impacts the speed of heart rate in beats per minute. The hypothesis stated that if the amount of time active is lengthened then the speed of the heart rate is expected to rise because when one is active, the cells of the body are using the oxygen quickly. The heart then needs to speed up in order to maintain homeostasis by rapidly providing oxygen to the working cells. The hypothesis is accepted because the data collected supports the initial prediction. There is a relationship between the amount of time spent active and the speed of heart rate: as the amount of time spent active rose, the data displayed that the speed that the heart was beating at had also increased. This relationship is visible in the data since the average resting heart rate was 79 beats per minutes, while the results show that the average heart rate after taking part in 30 seconds of activity had risen to 165 beats per minute, which is a significantly larger amount of beats per minute compared to the resting heart rate. Furthermore, the average heart rates after 10 and 20 seconds of activity were 124 and 152 beats per minute, and both of which are higher than the original average resting heartbeat of 79.

The two major things that will help an athlete while measuring the cardiovascular drift are progression and hydration levels. The heart rate of an athlete working hard during a workout should be no more than their maximum heart rate which is found by, if you’re a female take 226-age, if you’re a male take 220-age. If while doing a workout the maximum heart rate is exceeded by too much it may be necessary to take a break or slow down greatly. This may also help with traking the hydration of an athlete. If an athlete stays hydrated their core temperature will stay regulated which means they won’t sweat as much, which also means the heart won’t be under as much stress while transporting the oxygenated blood throughout the body to the
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
According to Social Learning Theory, Bandura (1989) suggested cognitive factors cannot be overlooked if learning is needed to be understood. Bandura has also noted that while reward and punishment substantially shape one 's personality, cognition has as much impact as they do. Also, the principles of behavioural approach have mainly been tested on animals. It implies some findings may not be applicable to a human being, which as a creature is much more complex than an animal.
Measuring your stress levels is important to maintain good health. There are three common research methods for measuring stress, physiological arousal, life events measurement, and daily hassle measurement. Physiological arousal typically measures blood pressure, heart rate, respiration rate, and galvanic skin resp...
Throughout the ages, humans have had an inherent interest in studying the complex area of human behaviour, even before psychology was established as a science. Because the study of behaviour is so broad and multifaceted, its scientific study poses particular challenges. Therefore, it can be beneficial to approach the scientific study of human behaviour from the perspective of cognitive psychology. This is the study of cognition, the mental processes that underlie human behaviour (Ling & Cattling, 2012).
