# Heart Rate Exercise Essay

Great Essays
Abstract:
Our experiment tests how body positions and body movements affect heart rate. We used 4 different subjects and 3 different trials including our control. For our hypothesis, we theorized that the more movements that a person does, the higher their heart rate will be. After doing this experiment, we found that the more movements and exercises your body does, the more increased your heart rate will become. There could be possible sources of error like any experiments, so this data is the most accurate data we could possibly achieve.
Introduction:
How do body positions and/or exercise affect heart rate? Our experiment is based around this essential question. From what is known, exercise increases heart rate. While exercising,
Our independent variable for this experiment is the body position or exercise. The dependent variable for this experiment is the heart rate after the exercise. If the rate of movement and exercise increases, then the heart rate will increase. The heart rate will increase because the heart will have to pump oxygen harder to get the oxygen to the muscles. The heart cycle will also play a major role because this cycle produces the heart beat which can be measured as heart rate.
Materials:
The materials needed for this experiment will be a yoga mat, the four test subjects, a set of stairs, and a heart grip monitor. The procedures of the experiment will be as follows:
Test Subject #1 lies down on the yoga
If the rate of movement and exercise increases, then the heart rate will increase because the heart must pump more oxygen to the muscles to perform the current task. During Trial 1, the average heart rate was of all the subjects was around 44-90 bpm. During Trial 2, the average heart rate for all the subjects was around 85-126 bpm. During Trial 3, the average heart rate for all the subjects was around 143-155 bpm. Trial 1 was the lowest intensity workout. Since it was at a lower intensity, the heart didn't need to work as hard to pump oxygen to the muscles. Trial 2 was the medium intensity workout. Since it was at a medium intensity, the heart had to work a little harder than the previous workout to pump oxygen to the muscles. And Trial 3 was the highest intensity workout. Since it was the highest intensity, the heart had to work extremely hard to pump oxygen to the muscles. As the trials progressed, you can see based on Table 1 and Figure 1 and 2 that the subjects' heart rate increased. Also, previous knowledge states that while exercising, the heart must speed up to pump oxygen and nutrients from food to the muscles which increases heart

This is due to the cardiovascular system having a function in thermoregulation, which regulates body temperature. As the surface area increases, extra heat can go through the skin and transfer out into the surrounding air. This is how the body cools down. A sport example of vasodilation could be a cyclist during a long race. Due to the long race, more blood will be pumped around the body and to working muscles, as their arteries would have enlarged for blood to flow and transport to working muscles.…

CARDIOVASCULAR HEART RATE ANTICIPATORY RESPONSE: There are nerves which directly supply our heart and also chemicals which our blood rapidly alter our heart rate, this main reasons nutrients and also extra oxygen to the working muscles before a race. When the body start to anticipate the physical exercise which is about to happen the body will prepare for it by increasing the heart rate slightly. ACTIVITY RESPONSE: The start of exercise, there are nerve centres in our brain which become aware of the cardiovascular activity. This results in adjustments which start the cardiovascular system to help increase our heart rate and also the local blood flow is improved to the right proportion to the intensity of activity. INCREASED BLOOD PRESSURE: Our blood pressure is the pressure of the blood against the walls of our arteries and there also result which in two forces.…

Explain the physiological changes that occur in the cardiovascular and respiratory systems in response to exercise. One of the main physiological changes that occur within the cardiovascular system in response to exercise is heart rate. When engaging in exercise, the amount of energy required increases instantaneously within the skeletal muscles. This sudden demand creates increasing stress on the cardio-respiratory system to remove the waste products and carbon dioxide from the cells and provide more oxygen for the working cells. This surge of extra energy that is needed requires the heart to pump faster and harder in order to increase the volume of blood being pumped there is an increase in beats per minute.…

Endurance athletes increase cardiac output with reduced peripheral vascular resistance, resulting in continuous volume changes for all cardiac chambers. Chamber dilated due to the volume overload so the heart can take in more blood. Strength training normal or slightly increase cardiac output, increased vascular resistance which results in increased blood pressure and LV afterload. The pressure overload causes the heart walls to increase in size to make the heart a stronger, more efficient heart during…

It was expected that the heart rates and blood pressure of the students would rise due to the exercise. This result was expected not only because it has been observed before, but also because exercise is a form of stress on the body. When human bodies are put under stress, their automatic nervous system and endocrine system become more activated. This heightened activation of these two systems prepares us for a fight or flight type situation. Some of the physical signs of this state include a higher heart rate and increased muscular tension (Insel and Roth 2013).…

It also results in an increase in the total mitochondrial content (Hawley, 2014). Resistance training causes an adaptation in the nervous system and in the increase of skeletal muscle size. This is shown mostly by hypertrophy, or an increase in the size of the current fibers in a muscle. Resistance training, like endurance, also shifts fiber type from fast to slow (Powers, 2015). The adaptations that occur to these types of training are overall beneficial to the human body and can help increase the performance of an…

→ Increase in heart rate ( i.e. increase in pulse rate) → More blood flow to the lungs and blood vessels in skeletal muscles. → Rate of gas exchange increases to supply more oxygen and glucose to support the aerobic respiration of skeletal muscles for more vigorous contraction . Reason ⅲ: To increase the rate of removal of carbon dioxide When the degrees of exercise increase, → The skeletal muscles contract more frequently. → Rate of respiration of the skeletal muscle cells increases in order to produce more energy for the rapid contraction of the skeletal muscles.…

Aerobic capacity of endurance athletes has been a consistent topic throughout research. Different sports require a certain amount of endurance to be successful on the field or court. Much of this research has been done on soccer players. These athletes consistently show a high maximal oxygen capacity, also known as VO2 max. Due to their higher aerobic fitness level they are able to perform closer to their maximum heart rate value as well.…

By knowing this information about a pulse, we can correctly identify the number of beats per minute. Each heartbeat is different from the next one (Watanabe). Heart rate can vary among people based on their fitness level and the degree of exercise they complete (“Aerobic Exercise”). Different body positions cause the cardiac autonomic drive to change in humans over the course of exercise (Watanabe). This leads to many positive effects on heart rate and blood…

Caffeine serves as a lignin that physically binds to the receptor and triggers the increase of cyclic AMP concentration (Watt & Routledge, 1986). The Increase in CAMP allows for the activation of protein Kinases, which increases heart rate and other metabolic/intracellular processes. Since the frog was not introduced to caffeine prior to the experiment, there was a drastic peak in the heart rate after just a couple minutes (Figure 1). This parallels the situations in humans because the people who don’t consume caffeine on a regular basis have more drastic effects on the heart rate versus those who consume caffeine on a daily basis. If more than the normal amount of caffeine (more than 500 mg) is consumed, there is a significant increase of heart rate and a spontaneous increase in blood pressure, although it is unclear of exactly why blood pressure increases when caffeine is introduced to the system.…
