• Introduction
Aerobic performance is stimulated by physical activity that makes the heart pump faster, as a result increasing the heart beats per minute measure. This experiment aims to rectify the effects of caffeine, a now well-known stimulant for the body. Beginning from its discovery, caffeine has grown to become a staple beginning many centuries ago, with the first preparation of coffee evident in the Middle East circa 1400s then it spread to the West into Europe and the Americas in the following centuries, and the first brew of tea was overseen by the Chinese dynasties in the years before the common era (BCE) and it only came to Europe through the exploits of Marco Polo and the Silk Road in the 1200s. (Burke, Desbrow, Spriet, 2013, …show more content…
However, the change in heartbeat of the participants taking caffeinated coffee show a higher rise in heartbeat compared to the placebo, which is an expected outcome as it shows caffeine has stimulated the brain in the time it has been present in the body. The large increase in heart beat from the post-treatment to post-exercise is due to the increased demand of oxygen in the body from exercising, regardless if the participant had taken a decaffeinated or a caffeinated coffee (Puente et al. 2017). However, the heart rate of the control being higher than the caffeinated coffee consumers post exercise is expected and it follows the hypothesis presented in the …show more content…
By being able to obtain information of the participants and their context, it allows for the results to have a new set of avenues for the explanation of the results. If information such as daily caffeine intake, mass, sexual hormones, menstrual cycle of a female, or physical capacity of an individual to complete an exercise were accounted for, the results obtained could be explained in more depth and an explanation of the results for the population can be found (Gonzaga et al. 2017). Also, the experiment could have more been more reliable through a bigger sample size for more repetition (Gonzaga et al. 2017). In the experiment, every individual was equally given 6g of coffee dissolved in 100 mL of hot water, this control is equal for everyone, however if the amount of caffeine was in ratio with the participant’s mass the concentration of caffeine for every individual will be equal (Burke et al. 2013, p.61) Compared to literature of the same question, the results obtained in this experiment reflects the effects of caffeine to; “increase physical and overall performance”, (Puente et al. 2017, Burke et al 2008), which correlates to a lower heart rate that equates to more oxygen required for aerobic respiration. The information and data obtained by this experiment can be applied in many situations of aerobic

How Does Caffeine Affect Heart Rate

Assignment 3 Caffeine and the Heart Rate I see people every morning getting their caffeine fix from coffee. I know that this is done to keep them energized and moving for the day ahead, like they say “America runs on Dunkin”. Sitting on the train I seen an advertisement sponsored by Sci Show it said “Did you know? The average person would need about 300 cups of coffee to over dose on caffeine.” I was honestly amazed at this fact. Sitting there I started thinking what effect caffeine (specifically…

The effect of caffeine on the heart rate of Daphnia AIM: In this experiment I am going to investigate the effect of different concentrations of caffeine on the heart rate of Daphnia. My hypothesis is that the higher the concentration of caffeine, the higher the heart rate. Also, I think that there would be a concentration of caffeine where the daphnia would not be able to live. INTRODUCTION: Daphnia are tiny crustaceans which are about 0.2 to 5 mm that live mainly in fresh water; lakes, rivers…

Hypothesis/ Null hypothesis : As the caffeine concentration rises, so does the mean heart rate of daphnia. Caffeine does not affect the heart rate of daphnia. CAFFEINE: Caffeine mimics some of the effects of adrenaline and noradrenaline in the heart. It also increases the amount of cAMP in the senatorial node. Caffeine has additional effects on the heart. Like adrenaline and noradrenaline, it can affect the main pumping chambers (ventricles), leading to an increase in the rate of contraction and…

sizes, their heartbeats can change in different environments. For our experiment we are seeing the reaction of different amounts of caffeine on the Daphnia Magna s heartbeat. This experiment is important to investigate because this will help us see the different amounts of caffeine effect on the heart rates on Daphnia Magna which have similar hearts to humans so we can input knowledge about the heart rates from this experiment onto humans. We…

Caffeine Research Paper

Americans consume some form of caffeine each day (Solan). Caffeine has many effects on the body, some beneficial while others are detrimental. Caffeine is a trimethylxanthine, meaning it has three methanes. It is also part of the methylxanthine family, a type of plant that contains a methyl group and is a stimulant (“Caffeine.” Drugs). With these factors, it takes longer for caffeine to be completely removed from the blood stream. Each time a molecule of caffeine passes through the kidneys, only…
