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.
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, …show more content…
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.
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 …show more content…
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
