Heart rate monitor

causes your heart rate to speed up because of the stress hormones and adrenaline being released into the blood stream. Once the acute stressor has passed everything in the body returns to normal. Chronic stress is defined above as long-term stress in the side text. Therefore, in chronic stress, your body is constantly in a state of fight or flight response, the heart beats fast, and adrenaline is constantly being released. Having chronic stress can put you at a high risk for having a heart…

stressful activity. People who do the most fitness activities tend to have a lower heart rate or beats per minute. Another important factor when you do something active is your surroundings, more specifically the scene. One would feel much relaxed if they ran in a park or forest in the morning rather than a chaotic sidewalk with a lot of people. Other methods such as deep breathing is absurd, all it does is help your heart drop its pulse but when you do something that get you to your feet, you…

Within the past few decades sports have experienced major revolutions. These major changes have resulted in new and more intense uses of the human body. More has become expected of athletes in professional sports. They are expected to be bigger, faster and stronger than those that played before them. Nonetheless, not all sports require the same abilities from their athlete's. High speed sports such as soccer and basketball depend upon different athletic abilities than sports such as tennis and…

Throughout life everyone is faced with challenging obstacles that they have to overcome, sadly I learned this for myself sooner than most. In October of 2012 I became a licensed driver in the state of Virginia. I was your typical sixteen year old boy with plans on taking road trips, modifying my car to increase its performance, and planning on never riding the school bus again. In three short months my world was turned upside down and I never thought it would be right again. It was December…

A fungus. That’s how the human race was taken out. Pathetic. Ophiocordyceps unilateralis. Also known as the zombie virus, it was discovered by British Naturalist Alfred Russel Wallace in 1859. It affected ants of the Camponotini tribe. The infected ant would leave its nest and travel to an area with the perfect temperature and humidity for fungal growth, then the ant would use its mandibles to hang on a leaf upside down until the inevitable death that would follow. Over the next one hundred and…

Introduction The purpose of this experiment was to test whether or not the heart rate of a daphnia was effected by three different solutions being added: alcohol, lactic acid and, caffeine. We determined that when alcohol was added the heart rate would decrease. When lactic acid was added the heart rate would decrease, as well. When caffeine was added the heart rate would increase. We determined that alcohol would slow the heart rate because it is a depressant. Since humans that drink alcohol…

The question that was answered in this experiment is, “Which aerobic exercise increases heart rate the most?” If a person runs then their heart rate will increase the most. The independent variable in this project was the different exercises that were done. These were running, jump roping, and doing jumping jacks. The dependent variable was the difference in heart rate after exercising. Some of the control variables were the amount of time that subjects exercised (15 minutes), the age of the…

greater than normal. (Beam, Adams, 2014) When a person has high blood pressure the body has to work harder to push blood through the circulatory system. This puts stresses on the body that can be treated with medication or lifestyle modifications. The heart works harder to pump blood from the left ventricle when a person has hypertension because it is working against a greater resistance. This places an increased chronic strain on the cardiovascular system, including the arteries and arterioles.…

equipment was set to collect its heart rate. We then placed the organism outside room temperature water into the 40°C water and allowed it acclimate for an interval of 30 seconds. When the time was met, we used the dropper to place the Daphnia Magna onto microscope tray with the net attached for support. Next, we examined the Daphnia Magna underneath the microscope for 10 seconds and collected its’ B.P.M. (blood pressure/minute). To do so, we calculated the heart beat count multiplied by 10…

As William Shakespeare stated, “Suspicion always haunts the guilty mind.” Edgar Allan Poe’s horror fiction, short story, “The Tell Tale Heart”, presents a dynamic character who does something wrong and feels guilty about it later in the story. Every night the narrator, a madman, would watch over the old man he was planning to kill. On the eighth night he watched over the man, the narrator killed him and hid his body underneath the floor of the old man’s house which made him feel proud. Soon the…
