Doing this will give you number of beats per minute. 3. Record resting heart rate in data table 4. Have participants put on headphones, making sure that they but the correct ear bud in the correct ear. (Right bud in right ear, Left bud in left ear) 5. Set the volume to only 25% full 6. Press play 7. When audio track is finished take the participants heart rate, using the process in steps 2-3. 8. Have participant rest for about 1 to 2 minutes. 9. Repeat steps 4-8, but instead of 25% full increase the volume to 44%. 10. After testing 44% volume, increase volume to 63%, and then continue repeating steps 4-8 testing 81%, and 100% full. 11. Collect and process data. VII.

Processed data presentation – [pic] X. Conclusion and evaluation – Your body’s heart rate is controlled by the body’s system of electrical and chemical responses regulates by the nervous system. The certain sections of your nervous system that works to control your heart rate are the sympathetic and parasympathetic nervous system.
The Term Paper on Big Data in Companies
Big data (also spelled Big Data) is a general term used to describe the voluminous amount of unstructured and semi-structured data a company creates — data that would take too much time and cost too much money to load into a relational database for analysis. Although Big data doesn’t refer to any specific quantity, the term is often used when speaking about petabytes and exabytes of ...
Loud sounds can cause the human body to undergoes changes, this includes, fast breathing, change in pupil dilation, and fast heart rate. The hypothesis that was tested in this experiment was if the volume of an audio track increases, the number of heartbeats per minute would increase as well. The results of this experiment were inconsistent with the hypothesis that was proposed. As you can see from the results, when the volume was increased the average number of beats per minute decreased, but when the volume was set to 100% full the average beats per minute did, in fact, increase. In comparison to other experiments, my results can be considered short.
In the experiment “ The Effects of Volume on Heart Rate and Blood Pressure, ” conducted by three university students at Colorado University, they found that when the song being played was at a high volume, their test subjects had a higher heart rate than when their subjects listened to soft music. Unlike their results, these results being presented show how their heart rates decreased, but in the end, like their experiment proved, heart rate did increase. The results of this experiment may be unreliable because of certain variables that were not taken into consideration. For example, the first three participants were tested outside, where the temperature was in the high 90s and low 100s, while the last two participants were tested inside in a cool environment.
This is important because another factor that can affect heart rate significantly is temperature. Another problem that may have made the results of this experiment less reliable is that in my procedures I did not take the resting heart rate again before each test. Instead I kept the first resting heart rate and used that to determine the change in heart rate. Your heart rate will most likely not be the same as the first resting heart rate. If I could repeat and modify this experiment, I would take into consideration the location of testing and the temperature of the location. I would also take the participants resting heart rate before each test. If I ould redo this experiment I would also go deeper into research and find other factors that affect heart rate that has to do with volume. In conclusion, my results did not prove my hypothesis to be true. But these results may not be as reliable as it could be if I repeated the experiment, and made certain modifications. XI.

The Essay on The Effects Of Physical Activity On Heart Rate And Breathing Rate
Aim:The aim of this practical is to investigate the effect of exercise on heart rate and breathing rate. We will use a digital heart rate monitor strapped on our chest while we perform different levels of exercise. A digital watch is also provided which receives signals from the heart rate monitor and displays your current heart rate on the screen. To measure the breathing rate at different levels ...
