Recommended: Experiments Regarding Heart Rate
Heart rate is the different intervals of a heart beat and is influenced in the sino-atrial node of the heart by parasympathetic and sympathetic input (Meule, et al., 2012). Heart rate is influenced by a person’s physical conditions, and health (Thayer et al., 2010). Body weight, alcohol, and smoking all influence our heart rate (Thayer et al., 2010; Karason et al., 1999). Our whole lifestyle influences our heart rate. From when we wake up to when we go to sleep, each activity our day has influences whether our heart rate increases or decreases. A data collection worksheet was given to me in a class and I had to fill out a survey and a list of activities. Each student had their information entered into a spreadsheet where I had to then choose two activities. One activity has a higher heart rate than the other and that is what we need to find using the scientific method. I hypothesize that the heart rate before resting is significantly lower than the heart rate when one eats dinner. The steps used in the scientific method is materials and methods, and the results that conclude whether the hypothesis was correct or wrong.
Materials and Methods
To complete the data sheet I used to finalize my hypothesis, I was given a sheet that had a survey and different activities I had to perform and check my pulse while doing them. The survey consists of questions that ask if I smoke, exercise, drink coffee, drink soda, drink Energy drinks, eat breakfast, and eat dinner. The activities included resting, walking, riding an excursive bike, drinking water, drinking soda, drinking coffee, taking an exam, driving through traffic, eating breakfast, eating dinner, and awakening from sleep. I had to record my pulse before, during, five minutes after, and...

...physically fit a person is. Karason states that weight loss is associated with an increase in the heart rate (1999). This concludes that if their were different people, the results would be different. In this experiment, my hypothesis was proven to be correct.

Over a three week period a test subject was instructed to come to the exercise physiology lab once a week. The purpose of the first week was to determine the baseline test data for the participant. During this first week, the subject was asked how many hours of sleep they had gotten the night before and how much they weighed. The subject was then instructed to put on a heart monitor and wear an O2 apparatus and begin running on a treadmill. This treadmill was set at zero incline for the beginning of the run until three minutes had passed. At the three minute mark the incline increased by 2.5%. After this the incline was continuously increased by 2.5% every two minutes. During this process, the VO2 and RER exchange rate of the subject was being tracked through the O2 apparatus. Their heart rate was recorded every 15 seconds. In addition, the subject was asked their perceived exertion at every increase in incline. The subject continued to run until they could not run anymore, at this time they would hop off the treadmill.
In human studies, caffeine and nicotine have been reported to increase the heart rate of human beings (2).
1.2 & 1.3 Explain The Cardiac Cycle And Describe How The Heart Rate Is Modified According To The Needs Of The Body
This lab experiment was conducted in a Texas Woman’s University exercise physiology lab room, on September 20, 2013. It consisted of two main participants: A trained participant (Male; 30 years old; 72 in. tall; 82.9 kg) and an untrained participant (Female; 20 years old; 65 in. tall; 75 kg). They were selected by my Prof. April Hartman to participate because they were best qualified to conduct the study in our class. Both participants were assigned to carry out the same experimental task. The Bruce Protocol (graded test) on a treadmill (mode of exercise) was used to conduct the VO2max test. The materials needed were: 1 metabolic cart (with computers); 2 mouthpieces; 1 nose clip; 1 treadmill; 1 RPE scale; 1 timer; pen; paper; and a HR monitor.

Biology literally means "the study of life". Biology is such a broad field, covering the minute workings of chemical machines inside our cells, to broad scale concepts of ecosystems and global climate change. Biologists study intimate details of the human brain, the composition of our genes, and even the functioning of our reproductive system. Biologists recently all but completed the deciphering of the human genome, the sequence of deoxyribonucleic acid (DNA) bases that may determine much of our innate capabilities and predispositions to certain forms of behavior and illnesses. DNA sequences have played major roles in criminal cases (O.J. Simpson, as well as the reversal of death penalties for many wrongfully convicted individuals), as well as the impeachment of President Clinton (the stain at least did not lie). We are bombarded with headlines about possible health risks from favorite foods (Chinese, Mexican, hamburgers, etc.) as well as the potential benefits of eating other foods such as cooked tomatoes. Informercials tout the benefits of metabolism-adjusting drugs for weight loss. Many Americans are turning to herbal remedies to ease arthritis pain, improve memory, as well as improve our moods. Can a biology book give you the answers to these questions? No, but it will enable you learn how to sift through the biases of investigators, the press, and others in a quest to critically evaluate the question. To be honest, five years after you are through with this class it is doubtful you would remember all the details of meatbolism. However, you will know where to look and maybe a little about the process of science that will allow you to make an informed decision. Will you be a scientist? Yes, in a way. You may not be formally trained as a science major, but you can think critically, solve problems, and have some idea about what science can and cannoit do. I hope you will be able to tell the shoe from the shinola.
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.

AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
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

This experiment is designed to test whether or not gender is a major contributing factor to the recovery heart rate in humans. Most would assume that the male heart rate would be considerably faster in recovery time than that of the female. This experiment furthers that assumption by eliminating uncontrolled variables such as age, build, and health conditions.
