Throughout this investigation, I will be conducting a number of experiments to help solve whether or not heart rate is affected by exercise. My aim is to identify the difference of every volunteer’s heart rate and take down how old they are so I can evaluate whether or not the age of a person make a difference in their bpm (beats per minute).
Many people know when you exercise for long periods of time; your breathing becomes more shallow and quick. The main human organ system used when exercising is the respiratory system. There are two types of respiration your body can carry out, aerobic, with oxygen, and anaerobic, without. The reason for getting tired from exercise is because when the body runs out of the oxygen it needs, anaerobic respiration takes its place. This respiration has no oxygen which means the body releases less energy and produces lactic acid. Lactic acid is a poisonous waste product that stops muscles contracting and relaxing. In this investigation, I will be finding out whether exercise that has two different types of respiration has a strong affect on the heart and its’ cardiac cycle.
I believe that throughout this investigation, the heart rate of the people of the people I will be experimenting on will speed up and rise to a very fast pace. I also think that although the heart rate is bound to increase, the pulse will eventually reach its maximum acceleration and stay steady after a long period of exercising. I do not believe that will be the result in my experiment for a main reason that the longest period of time people will be exercising in is 2.5 minutes, which is not long enough to get the heart rate at its maximum speed of acceleration.
In this investigation, I will be attempting to make this e...

.... The tests were all similar to one another and the results were moving as predicted. After repeating it with three different people per age group, most of the results had no big differences. The range bars were not very far apart and were closer together because of how similar the results were even before calculating the averages. This shows me my results are quite reliable because most of the data collected was alike, so they were not misinterpreted or mistakes.
I think the results do fit with my conclusion and my theory. Most of the results are in the line of best fit and there is only a few odd results all together, if more results were taken, it would have helped justify my theory that the heart rate will eventually stop increasing, even when you carry on exercising. I think if we used longer time periods for exercise, we could have seen a bigger effect.
My hypothesis for this experiment is that the higher the levels of caffeine the water flea was exposed to, the quicker the heart rate would be.
In the study it was hypothesized, that the pulse rate does not increase after a step test exercise. This hypothesis is not valid because the result of the step test proves otherwise. In the study, the individuals who participated in the step test took their pulse rates before and after the step test, looking at the overall results, figures and the averages of both tests, we can conclude that the step test exercise does affect the pulse rate of an individual.
In this lab we try and figure out the effects of exercise on cellular respiration, and identify a role of carbon dioxide production, breathing rate, and heart rate in determining the rate of cellular respiration. To do this we made a Phenol Red solution and used a straw to blow into it with no exercise to see how long it would take for the color of the Phenol Red solution to change, after this we measured our heart, and breathing rate. Then we did these same steps again after 1 minute, then another 2 minutes of exercising (Note: This lab was incomplete). The problem of this lab is “ How will carbon exercising, and increased carbon dioxide production affect the color of the Phenol Red, our heart rate, and our breathing rate. I hypothesize that if we exercise then we will affect our cellular respiration, and cause the Phenol Red to change color in a faster rate, because when we exercise we breathe heavily resulting in a higher carbon dioxide production which will cause the Phenol Red to change at a faster rate.
Heart rate variability (HRV) reflects the variations in the intervals between heart beats (R waves) over time. The time between two consecutive R waves is termed the R-R interval; it is measured in milliseconds, and is controlled by the autonomic nervous system 1. HRV is a non-invasive method for interpreting autonomic nervous system modulation and provides information relating to each branch of the autonomic nervous system 2. Analysis of the beat to beat variability provides an insight into the relative contributions of the sympathetic and parasympathetic components of the autonomic nervous system’s control of the heart 34. In healthy individuals it is now widely agreed that under normal resting conditions, a high HRV is an indicator that the parasympathetic pathway is dominant over the sympathetic pathway. Consequentially, a large number of various disease states for example, cardiovascular disease have been linked to a low HRV reflecting increased sympathetic activity at rest 5. Studies have reported that regular practice of physical activity improves ...

... uptake during submaximal exercise but did increase heart rate and the rate-pressure product at rest and during both exercise and recovery’.
The heart rate will be lowest when the subject is relaxed because the heart will have enough blood to pump in less beats per minute. When the subject sits up, it will increase its heart rate. However, the heart rate will be at its highest after the subject had exercised due to the body trying to satisfy itself by sending more oxygenated blood to where it is needed most.
Introduction: In year 10, biology, we have been studying the heart: the functions of the heart, the parts of the heart (ventricle, atrium) and heart problems. Besides that we have been studying the heart rate of humans. We were asked to create an experiment to see what affects heart rate. We discovered that diet, stress, cholesterol level, excitement, mass, age, temperature and exercise affected the heart. Diet and exercise were the only 2 doable and so my partner and I chose exercise. We determined that as the intensity of an exercise increased so did the heart rate of the person performing it.
The two major things that will help an athlete while measuring the cardiovascular drift are progression and hydration levels. The heart rate of an athlete working hard during a workout should be no more than their maximum heart rate which is found by, if you’re a female take 226-age, if you’re a male take 220-age. If while doing a workout the maximum heart rate is exceeded by too much it may be necessary to take a break or slow down greatly. This may also help with traking the hydration of an athlete. If an athlete stays hydrated their core temperature will stay regulated which means they won’t sweat as much, which also means the heart won’t be under as much stress while transporting the oxygenated blood throughout the body to the
The hypotheses for this lab stated, “If a person is given caffeinated soda, and then goes and completes an activity , their BPM should be slightly higher than somebody who has completed the activity without any soda because 1. the caffeine should definitely have an affect with heart rate , and just eating may get blood pumping in order to digest and absorb food.”
Statistically females have approximately a 12% higher heart rate than males (Livestrong.com), taking into consideration of this natural differential between the sexes the averages have been calculated by the differences of initial heart rate and final heart rate. By doing so the results are able to correlate accurately against one another, demonstrating the increase/decrease of the participant’s heart rate. However, the results gathered exhibit inconsistency due to the averaging of the beats per minute between the males and females. This is as the anomalous figures of the sample skewed the results, altering the figures to be less/more significant than necessary. Evident in participant 693 whose heart rate decreased of 3 beats in the film excerpt
The materials used: one wristwatch (with second hand), two variably indifferent humans (one male, one female), and a standard staircase at CCC. The method was simple: two test subjects were exposed to two trials involving one minute of physical activity and x minutes needed for the recovery of the heart rate. Before the experiment began, each subject's resting heart rate was taken. This would become the controlled variable. Next, each subject ran up one set of stairs at CCC, one stair at a time, for one minute. After one minute of activity, the subjects stopped and began taking his or her heart rate.
2008). In other words, there is an interaction between caffeine intake and muscle mass that determines pulse rate and in this experiment, muscle mass was a variable that was not accounted for. Furthermore, the resting pulse rate response to caffeine consumption prior to exercise is considered one of the most variable parameters of those in the study. Because this experiment measured resting pulse rate less than one hour before exercise, it is not completely reliable as a study by Bailey (1989) similarly suggested the implications of pulse rate variability to be a factor of the fluctuating results across subjects despite
As predicted, the time it took for the bromothymol blue to turn to yellow decreased after more amounts of exercise. The subjects heart rates increased the more they ran up and down stairs as the body needed to use the bloodstream to bring more oxygen to the muscles. To let your bloodstream provide more oxygen, the heart begins beating hard and fast (“New Health Advisor”, 2016) to move blood quicker. This concludes the hypothesis that the time will decrease due to more CO2 being released.
There are multiple possibilities for future research. In particular, testing to discover what relationship the length of time spent exercising holds with the respiratory rate of a subject. Another possibility could include testing to see if the intensity holds an impact on heart rate. Alternatively, an experiment to test at what length of time the heart reaches target heart rate could be conducted or even further or to test what different types of exercise produce what sorts of heart rate. Most importantly, simply repeating the experiment with many more trials would provide much more information and data, which could possibly lead to more accurate results and conclusions.
