Coffee-Heart Rate Research Paper

Aim: The aim of this experiment is to understand the affect of the drug Caffeine on the rate of a Daphnia’s heartbeat. This is to understand the affect of caffeine on a human’s heart rate and the use of daphnia keeps the experiment fair and safe.

The purpose of this experiment was to determine how affected the heart rate of the daphnia. The results gained from this experiment aids scientific researchers in finding out how caffeine can affect heart rate as well as human health.

A hypothesis can state the following: there exists a positive relationship between employee performance and flexible working hours. Whereas a research question could generally be: do flexible working hours affect workers productivity? You can clearly see that the hypothesis states clearly and it is more specific in its prediction unlike the research question (eNotes.com, Inc 2011).

The researchers included both a hypothesis and research questions. They stated a hypothesis, however it is a research hypothesis versus a null hypothesis. A research hypothesis explains there is correlation between two or more variables. A null hypothesis is a classification of hypotheses that states there is no connection between the independent and dependent variables. Statistical testing is performed to determine whether the statement is acceptable or not. Whereas the research question is an analysis statement detailing the variables and population of the specified research study (Adams, 2015). The hypothesis, the authors were hoping to prove, was whether the use of music would reduce pain and anxiety in postoperative pain in a particular patient population during a defined time frame (Allred et al., 2010). An example of a null hypothesis for this study would state music would have no effect on postoperative pain in a particular patient population during a defined time frame. There were four research questions the researchers attempted to answer. Three of the four questioned the effect of music on the patient’s pain, anxiety, and physiologic parameters. However the fourth question pertained to the impact of music on the amount of opioids taken from the beginning of the intervention until six hours later (Allred et al., 2010). The clinicians had not mentioned this component of the study before

Premiere Hospital of Newport Beach (PHNB) is concerned about providing caffeinated coffee to patients waiting to be seen in their waiting room. Other hospitals serve it, but PHNB wants to make an informed decision around this based scientific inquiry. The big question for hospital administration is whether caffeinated drinks have a significant impact on heart rates. The research is aimed at evaluating

In this experiment we are going to be using daphnia’s to determine how certain drugs effect our heart rate, whether they increase or decrease and if they do, how much they increase or decrease. We will do this by obtaining a daphnia’s rest heart rate, dropping a sample of the certain drug onto the daphnia and observing the new heart rate. The drugs that we are going to be using are: diet pill, adrenalin, sleeping pill, coffee, and tea. It is predicted that coffee and tea will increase the heart rate of the daphnia seeing they both have caffeine in it. Coffee has about 95-200 mg of caffeine in it while tea only has 11-47 mg of caffeine so coffee should raise the heart rate slightly more than tea.

The aim of this experiment is to observe whether caffeine has any significant effect on heart rate. To test this, daphnia will be placed in water and then caffeine solution, so the

An independent samples t-test was conducted to examine the difference between experimental conditions on test performance. The results indicated a significant difference between participants who consumed the caffeinated beverage and participants who did not, with participants in the caffeinated group (M = 7.64, SD = 2.41) performing worse than participants in the non-caffeinated group (M = 9.81, SD = 3.16), t (97) = 2.14, p < .05.

This paper explores and explains the findings of the heart rate experiment conducted by the students of Grand Canyon University for the Anatomy and Physiology 202 Laboratory course. Over a two week time span, students were asked to record their heart rate, before, during, and after activities as instructed by the professor. Specifically, this paper focuses on the female students, comparing the heart rates of individuals who reported that they drink coffee versus those females who reported that they do not drink coffee. The effects of caffeine contained in the coffee were examined and it was noted that those who drink coffee have lower heart rates before, during, and after times of examination. These findings suggested that the hypothesis proposed prior to research, Females Who Drink Coffee Have a Higher Heart Rate Prior to Exams, was an incorrect statement.

In 1999 Jack Kevorkian was found guilty of second degree murder and sentenced to 10-20 years in prison. The 70-year old from Michigan was convicted after he was videotaped delivering the lethal injection to 52-year old Thomas Youk, who had been suffering from a neurodegenerative disease. Before then, Kevorkian had lobbied for experiments to be tested on inmates on death row and suicide dedicated clinics. His status as a euthanasia lobbyist later earned him the title of “Doctor Death”. Kevorkian was involved in as many as 130 assisted suicides over a 9 year period. When he began his work, there were no laws against assisted suicide in his state, a fact which would later be pivotal in the court decision regarding Hugh Gale’s death. On

The following procedures and materials were thought up by my partner and me, which was done on a small scale due to lack of time to perform a full fledge experiment that involved a large sample size. Our project consisted of a sample size of ten people in which each subject was given a survey to complete and a consent form to sign stating what the experiment was about. We also expressed with the up most confidence that their scores and identities within this research will be kept confidential. We articulated to each subject to not drink any caffeine four hours prior to the experiment so that we would not have any type of bias. My partner and I obtained ten cups (regular coffee cups) on day 1 and filled each cup with 200ml of water, in which five out of the ten cups had the caffeine pill ( dissolve in water before giving to subject)

An estimated sample size of 235 study subjects across two centers in Hawaii and Massachusetts is foreseen. This sample size was selected based on the literature, and standard statistics charts showing an effect size, E/S = 0.30, α = 0.050, and β = 0.100, and at a power = 0.900. It is envisaged that there will be a total of 117 study subjects at the center in Hawaii and 118 study subjects at the center in Massachusetts. An effect size > 0.10 was chosen in order to detect a meaningful magnitude of the association of coffee consumption with the incidence of PDD in the population. A large enough sample

Caffeine and its Long-term Physiological Changes To many people, caffeine seems like more of a necessity to start the day, or keep the day going, rather than a potentially harmful drug; however, most do not realize the long-term physiological changes that can occur as reported by several users. According to National Geographic, consumers spend 30 million dollars every year on caffeine tablets and roughly 50 billion dollars on caffeinated soda. Caffeine is a drug and as such makes changes the bodies. When people consume food or drink with caffeine in it the body responds by a raise the blood pressure, exciting the central nervous system, endorses urine formation, and speed up the action of the heart

Caffeine being a drug affects people in many areas due to it being a stimulant. The focus of this proposal concerns the affects of impulse control concerning cognitive memory of individuals who consume caffeine and those who do not. There have been many studies concerning caffeine and cognitive ability and possible differences between those who consume caffeine and those who abstain but knowing the effects of impulse control on memorization while using caffeine would be interesting to understand.

Antiarrhythmic drugs are prescribed for the treatment of heart conditions caused by arrhythmias. Arrhythmias are when the heart is beating abnormally, such as atrial fibrillation, atrial flutter, ventricular fibrillation and ventricular tachycardia. There are five different groups of antiarrhythmic drugs. Dependent on your symptoms and how severe they are will be the determining factor of what type of antiarrhythmic drug you will take. With any type of medication, you take you will need to keep an eye out for side effects. Antiarrhythmic agents when used as directed can treat and prevent further implications and possibly save your life.
