The part of the method went really well was that we made steps for recovering time.. The recovering

All subjects were healthy third year physiology students (n=10), aged between 19-24. Basal heart rate was measured using an OMRON, time 0, after which each participant consumed 250 ml of Red Bull each. Heart Rate was measured again at 30 mins, 60 mins and 90 mins after the full consumption of Red Bull. For each time point three readings were taken and the average was used. Participants were required to sit down during the whole procedure, and remain claim. A paired t-test was performed to determine whether there was a significant difference in heart rate at the start and end of the trial. Significance level was set at p<0.05.

The cardiovascular response is triggered by excessive exercise within a short-term anaerobic exercise (such as running for 30 minutes). This initial response starts with the release of adrenaline that causes an increase in heart rate, meaning an increase in cardiac output. This activity

The heart rates of participants was tested before the step test, one minute, two minutes, and three minutes after the step test was performed in this experiment. Since heart rate increases while someone is performing physical activity, it was expected that heart rates of the students would be higher than before the step

Once the thirty seconds was up, the person counting stopped and the heart rate (beats per second) was recorded. The same process was done again, but the counter counted the hearts beats for 1 minute. Again, after the 1-minute was up the heart rate was recorded for 1 minute. The same process was done again for 2 minutes, afterwards being recorded.

In addition, heart rates vary according to exercise, physical needs, age, gender, air temperature, etc. In this experiment the dependent variable

Heart rate increases to circulate more oxygen through your blood stream giving more ATP for your muscles. Exercise encourages the body to grow new blood

There are several pathways that can explain each experiment that was performed and why it happened. The first experiment was to test to see how exercise affects BP as well as HR. It is hypothesized that immediately after exercise both subjects will have an increase in their arterial pressure as well as their heart rate will increase. This is because when a person is exercising, their blood is pumping faster, which is causing the heart to beat faster and the pressure to rise. Subject #1 (well conditioned) baseline BP was 117/61 mmHg and had a HR of 66 bpm. Where as subject #2 (poor conditioned) baseline BP was 110/70 mmHg and HR had a HR of 80 bpm. Immediately after exercise both subjects BP and HR increased significantly. Subject #1’s BP went

Before we started the lab experiment, we had to grab a few equipment such as one stethoscope, so we could actually hear the participant's heart rate, at least four to six alcohol prep pads to cleaning the earpieces of the stethoscope, one blood pressure cuff, one heart rate monitor chest strap, and one heart rate monitor watch. After we gather all the equipment that we needed, the participant had to position the heart rate monitor straps around his or her chest while having it in direct contact with their skin. Then, the participant had to position themselves on the cycling or the treadmill walking for about 3-5 minutes due to the measurements. Both participants were required to measure and record 4 HR measurements for each other. The first

In conclusion, this experiment was successful. The purpose of the experiment was to observe the change in heartbeats per minute before and after a physical activity, in this case, ten jumping jacks. As predicted, the data proved that the hypothesis was correct because you can clearly see in the graph that the heart rate after exercise was higher. One point that I noticed from the data was that the ten jumping jacks affected the subjects differently. Subject two’s heart rate after exercise was significantly higher than subject one’s. Subject one’s heart rate increased only slightly; whereas subject two’s heart rate increased significantly. This experiment is a good basis for additional testing involving heart rates and exercise. If this investigation

Results from the experiment can be found below in table 2. As apparent in the table, with an increase in the intensity of the exercise, the heart rate and blood pressure both increased. An important observation from the data is that the systolic blood pressure steadily increased as we increased the intensity. However, the diastolic blood pressure remained relatively constant as the intensity of the exercise increased. The heart rate steadily increased with the increase of intensity as well.

Analysis, Discussion, and Conclusion: The purpose of this experiment was to determine whether athletes or non-athletes would experience a high percent change in heart rate after having experienced a raised heart rate, caused by running one lap around the high school track. The agreed upon hypothesis was that the five subjects in the “athletes” category would recover faster, in comparison to the “non-athlete” category, due to the fact that the athletes’ hearts are more frequently exposed to elevated heart rates. After examining the collected data, it was determined that the hypothesis was refuted, given that the average percent change of the athletes was +16.94%, which is 5.22% greater than the average percent change of non-athletes, as shown in CHART #3 -

Tim’s heart-rate started at the lowest (70 bpm) and increased the most, ending at 106 bpm. That’s an increase of 36 bmp. Tim is 14 years old and was the unhealthiest of all the subjects with a fitness level of 3. He was the only subject who had any trouble getting through the sit-ups, as he was having a tougher time getting through the last 5 of the set of 20 sit-ups. He was the only subject breathing heavily after the experiment. I believe because Tim had to work harder than any of the other subjects to complete the 20 sit-ups, his heart-rate also increased more.

Then I went away to put them into their type A or B. then I had one person at a time doing the same dot-to-dot (appendix c) as I the investigator took their pulse before they start then the second time as they are looking for the missing number and third time after they had finished the dot-to-dot then record the results the pulse was counted by the minute hand for one minute ach time this was repeated twenty times throughout the day same environment. Once the experiment had finished I put up a on the notice board a thank you for your participation and if you would like to know the results or any questions about Type A or Type B come and see me.

This experiment was conducted to see how exercise affects breathing and heart rates. My hypothesis was that if exercise puts strain on the body, then the heart and breathing rates will increase and I was correct. This is because as the exercise increased the heart and breathing rates also increased. For example in trial #1 the resting heart rate was 96 beats per minute then after 1 minute of exercise it increased to 144 beats per minute and then increased again to 160 beats per minute after 4 minutes of exercise. After the exercise was completed the heart rate went back down to 132 beats showing that the heart rate is based off of the amount of exercise rather than it just going increasing or decreasing randomly. The breathing rate also increased

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
