Statistically females have approximately a 12% higher heart rate than males (Livestrong.com), taking into consideration of this natural differential between the sexes the averages have been calculated by the differences of initial heart rate and final heart rate. By doing so the results are able to correlate accurately against one another, demonstrating the increase/decrease of the participant’s heart rate. However, the results gathered exhibit inconsistency due to the averaging of the beats per minute between the males and females. This is as the anomalous figures of the sample skewed the results, altering the figures to be less/more significant than necessary. Evident in participant 693 whose heart rate decreased of 3 beats in the film excerpt …show more content…
Crazy, Stupid Love, whilst the rest of the female participant’s heart rate increased of roughly 5-8 beats. Also, evident in male participant 566 who’s heart rate increase of 19 beats, whereas, the rest of the male participant’s heart rate increase of approximately 10 beats. Explanations as to why the results gathered demonstrate an increase could be caused by multiple variables.
The influence of food eaten, age and sex of the person all affect the heart rate. Since there was no prior calming session before the experiment it is to be expected that the heart rate of the students are higher than their normal resting rate due to just finishing lunch. The understanding of the film excerpts context by each of the participants also alters the heart rate. According to this investigation The Patriot is the justified film excerpt and Crazy, Stupid Love is the non-justified film excerpt. However, for those who have seen both movies their opinion may be contradicting to the investigation. One participant’s heart rate may have not increased because of the understanding of the situation. The extremity of the violence also plays a key role in the results gathered. This is as the two film excerpts of justified and non-justified violence were two levels of violence with one film portraying mild/moderate violence (punching, kicking and so on) to a murderous rampage, with masses of gore (extreme violence). The drastic extremes of the violence interferes with the data collected as it isn’t experimenting exclusively of the heart rate towards justified and non-justified violence, rather less harmful acts of violence verse murder and the heart rate towards those
variables. The experiment conducted demonstrated an increase of heart rate between males and females in the 3 film excerpts examined, with a few anomalous figures skewing the data. The fact that there was no clarification of the context of each of the film excerpts it is an assertion, which, presumably this altered the heart rate of each of the participants to varying degrees. Also taking into consideration of the limited controlled variables, the experiment concluded that the sample of male participant’s perception of justified verse non-justified violence is less significant than females.
I predicted that the blackworms in higher caffeinated solutions would have higher pulse rates, because caffeine is known to increase blood pressure and heart rate. However as far as scientists know, invertebrates are not expected to have a strong response to caffeine like vertebrates do. Also, caffeine in low doses is known to lower pulse rate. The results do not support my hypothesis. The results show that when black worms are placed in caffeinated solutions, their pulse rates on average are lower than those placed in a solution with no caffeine. A possible flaw that may have occurred during experimentation is that the petri dishes were not properly cleansed, or that there were other properties in the water that influenced the outcome. To eliminate these flaws, I could have boiled the petri dishes and water to insure that there were no other properties to influence the data. Further experimentation should be performed with higher doses of caffeine to further insure that caffeine does in fact lower their pulse rate. The insufficient number of trials performed lead to less confidence in my conclusion that caffeine lowers the heart rate in
The experiment studies the effects of Red Bull and its major components on the heart rate of a Daphnia. The experiment focuses on the effects of conditions on the cardiovascular system. The Cardiovascular system is responsible for the transport of blood, oxygen, nutrients and waste circulating the body. It consists of the heart, vessels, and blood as in closed circulatory system and hemolymph in open circulatory system, the cardiovascular system is also responsible for thermoregulation in the body. (Gonzalez, 2012). The heart helps pump blood to the lungs and rest of the body. The pumping of heart or the contraction and relaxation of heart determines the heart rate and depends on multiple chemicals that we could influence by using stimulants, depressants, varying temperatures, aerobic, and anaerobic
It was placed on a slide, a couple drops of water was placed on the slide to keep it moisturized. Next, we used a microscope to observe the heart beating in the transparent animal. According to the lab report on page 98 the normal heartbeats are about 350 per minute. By using a pencil and paper, we made a small dash for every heartbeat over a 15 second interval. Than we continued to repeat the observation of the heartbeats 3 more times for a total of 4 observations. We than totaled up the number of dashes and calculated the average of the four 15 second observations, this was labeled “Normal Heart Rate” on Table 1. Next we added 1 drop of an “unknown” solution that was assigned, we made sure to determine the average normal heart rate before doing do. The same procedure outlined above was conducted. The records were than placed in table 1. We than used water in replace of the unknown solution. The same procedure was conducted, we analyzed whether the Daphnia had recovered or not. Lastly our records were compared among our
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.
To determine if the intensity of exercise affects the heart rate of a 15-year-old boy. Apparatus - 2 stopwatches - 1 laptop (beep test) - 1 fire glass tape (min. 20 meters) - Chalk to mark 20 meters (start to finish). Method 1) Get beep test ready on laptop from - http://www.youtube.com/watch?v=e0U_yQITBks - 2) Bring five male subjects ready at the starting line to run the beep test. 3) Mark 20 meters on the ground outside on the AstroTurf using a long tape.
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.
The purpose of the article, “The effect of video game violence on physiological desensitization to real-life violence”, written by Nicholas L.Carnagey, Craig A. Anderson and Brad J. Bushman is to show the effect that video games has on physiological desensitization. Psychological Desensitization is defined as the diminished emotional responsiveness to a negative, aversive or positive stimulus after repeated exposure to it. In other words the purpose of the article was to experiment whether or not people who played violent games were able to still be aware of the violence happening around them. The authors set up this study by having the participants report their media habits and then having them play one of eight violent or nonviolent games for a small period of time. Then the participants
Many people have different perspectives when it comes to the topic of love. The word love has been tossed around by everybody and not very many people really understand the true meaning of love. There are some exceptions, but I think this is especially true for teenagers and young adults. I might be one of those people who do not fully understand the topic of love, but I hope to better understand the topic of love and its true meaning is this course.
Love is a weird feeling. It’s been said that love has nothing to do with your heart, it 's all chemical reactions inside of your brain. Infatuation, attraction, crush is such powerful feelings that people do think that they are in love. Also, it is blind to the other person’s weaknesses and exaggerates his or her strengths. Similarly, infatuation often fades within a short time. However, true love is so real and so strong, strong enough that if it came down to it you would even die for your partner. Love as much more than a feeling. It is based on a well-rounded knowledge of a person’s strengths and weaknesses. Not so in the case of China and Jeremy, in T. Coraghessan Boyle “The Love of my Life.” Before we talk about them
Love is one of those things that means different things to different people. If you would look the word love up in the dictionary, you would find this: “an intense feeling of deep affection.” For some people, love can be purely romantic or even just purely sexual. For others, real love can only exist between family members or between people and a god. For some people, it is felt for your partners, family, pets, or even inanimate objects. None of the people are right or wrong, but I do know one thing, love is very powerful. Love is overused in today's world, people say they love someone because of the way they look or their body. That isn't love. To me, love is the most spectacular, indescribable, deep euphoric
We all fall in love at some point in our lives whether it be a passion, faith, or another person. Falling in love is a natural human behavior. It ensures the continuance of the human race through reproduction. Love is often considered a mystery because of its unexplainable feelings. It is the personal and affectionate relationship between two people. Researchers have discovered the biological reasons behind falling in love. The brain controls the signals that release chemicals and hormones in your body to give that rush that love brings.
Love happens when you least expect it. It can happen on the street corner, at the bar, at the grocery store, the park. That’s one of the greatest things about love. As for me I found love in the pouring down rain in the middle of the street. I fell in love with a man who I never thought in a million years I’d fall for. A man who is loving, caring and respectful. The night I laid my eyes on him I knew he was it. He came into my life at a point when I was unraveling and losing control. I was lost for two years after my high school sweetheart and I broke up, I thought I was never going to find real love, but I did. He saved me and I remember every minute from that night.
I disagree and would argue that being in love and loving someone has two very different meanings. The word love is used too loosely. Loving someone and being in love with someone are two very different things. Although I am not a love master, being only 19 years old and in two serious relationships in my life, I have come to realize being in love is something special. I believe when you are in love it’s not a choice, that person is picked for you. You are addicted to them, you want all your friends and family to love them as much as you do, you are there when they succeed and there when they fail, you miss them every minute you are apart and you unconditionally love them, even when times get hard.
There are many positive things and negative things about the movie and the story. In the movie
What is love? Love is a very special and meaningful word to each human being. Each human being has his/her own thoughts about love to guide himself/herself to land safely and smoothly into the kingdom of Love. Without this preconceived idea of love, people would be acting like a blind person searching for the light with thousand of obstacles in front of him.
