Heart Rate Experiment

Abstract
The purpose of this exercise laboratory experiment was to, analyse and observe the role that exercise plays in affecting the blood pressure and heart rate of a patient, with and without the consumption of caffeine. In this experiment, a cycle ergometer (Monark 824E, Monark Exercise, Sweden) was used in an incremental style type exercise that measured the fourteen healthy participants blood pressure and heart rate at various interval stages. The blood pressure and heart rate were recorded in order to obtain an understanding of the impact this would have on the cardiovascular system. The experiment initially revealed that the participants who consumed caffeine before the experiment had a very slight differential increase in results compared

Initially, the class broke up into groups of five with each member of the group having a role to play in the experiment. The first volunteer from the group performed the ergometer intensity exercise (Monark 824E, Monark Exercise, Sweden). The second group member was the timekeeper, who’s main objective was to alert the group of when to observe and record the participant’s blood pressure as well as add weight to the cradle of the ergometer (Monark 824E, Monark Exercise, Sweden). The third group member was responsible for monitoring and observing the participant’s blood pressure using the blood pressure monitor supplied (Omron, M3, Milton Keynes, UK). The fourth member of the group obtained the rate of perceived exertion from the participant using the Borg scale and also to observe the participant’s heart rate using the heart rate monitor provided (Polar Heart rate monitors, T31, Finland). The fifth and final member of the group recorded all the data obtained throughout the stages of the …show more content…
Whether the participants consumed caffeine or not, they all showed the same increased heart rate when obtained just after the exercise phase of the exercise. Once the recovery phase commenced, the heart rate started to find a steadying rate and maintained that level. This is important because it indicates that the heart obtained a consistency for an interval of time and maintained the substantial level (MacMasters et al, 1987). As the recovery phase continued, the heart rate in all participants decreased incrementally until it met the resting rate. This is due to the activation of the parasympathetic system and the decrease in oxygen demand lowering the function (MacMasters et al,

    First of all, the Hand-Grip or Exercise Heart Rate Monitor was connected to the TI graphing calculator to the computer interface. Second, The subject was sitting in a relaxed position in a chair. She has took a fast breath about 60 second, and the tester has noticed and recognized what happen during hyperventilation. After that, the tester has recognized what happen during hypoventilation by letting the subject to breath slowly about 60 second, and take a deep breath and hold it as possible. Finally, the data was collected from the graph.…

    The trend observed in RESULTS is inconsistent that it is difficult to make an accurate judgment on the ergogenic effect of caffeine. A significant increase in the mean pulse rate was observed in both caffeinated group (50.0 beats/min) and decaffeinated group (47.9 beats/min) from pre-treatment to post-exercise (Table 1). However, the difference of change in the mean pulse rate (2.1 beats/min) between the two groups is small and considered statistically insignificant. Contrary to what happened in the mean pulse rate, the decaffeinated group experienced a higher increase (7.8 breaths/min) in the mean respiration rate than the caffeinated group did (7.0 breaths/min) in response to caffeine ingestion (Table 2). Yet, the difference in the respiration rate change (0.8 breaths/min) between the two groups is statistically irrelevant.…

    During exercise, your muscles should metabolise faster as they require both more oxygen and nutrients. This then makes the heart pump the blood harder and faster to keep up with the demand, as the heart is doing more work to supply the blood. This means that more oxygen is required, meaning, the response given is breathing being increased so that oxygen is pumped to all cells quicker. Due to homeostasis, levels of oxygen in the blood are always being measured, ensuring oxygen, carbon dioxide and pH levels return to their norm. Messages that are sent to the effectors informing them that the breathing rate has been increased, however, will decrease again when all activity has been stopped.…

    We chose to conduct this experiment because both Amber and I are interested in athletics and the science side of it. There have been several researchers studying the effects of caffeine, and they believe it can enhance athletic performance and agility in sports. Because of this we believe if caffeine levels are increased, then time taken to run a lap will decrease when time is a function of caffeine level. To test this we will have a group of ten subject male and female who around the same athletic capabilities. Then, we will give them a set volume of liquid at different caffeine levels to see if the subjects running time changes with the caffeine.…

    However, according to the t-test, this result was nonsignificant. The data at peak work rate, however, diverged from my hypothesis since the cardiac output was lower for the caffeinated group. The reason a decrease in cardiac output occurred is due to decreased sympathetic activity, stroke volume, and heart rate as exercise intensity increased. Another reason might be due to the fact the non-caffeinated group contained a larger number of athletic individuals than the non-caffeinated group. In previous studies caffeine had no effect on contractility or cardiac output so the significant decrease observed might have been due to the small population used in the experiment (Pincomb et al.,…

    Exercise Physiology It has long been thought that strenuous or prolonged exercise can affect the human’s endocrine system. This is an interesting scenario because endocrine system synthase performs as a negative feedback system. This means that when there is an unusually high level of a hormone in the blood, a signal will be sent back and production of that particular hormone will be stopped. The negative feedback system can easily keep all hormones levels at the optimal level for humans.…

    The intention of this report was to review the scientific literature, to effectively guide coaches, and athletes on the most suitable and efficient means to apply caffeine supplementation to the type of sports performance, intensity, and duration. Due to the impracticalities around testing for caffeine, variations in caffeine sensitivity and wide availability of caffeine in food and drinks, conflicting evidence surrounding the optimal dosage and the effects of caffeine on sports performance, caffeine has been removed from the World Anti-Doping Agency's list of banned substances. Currently, more research needs to be performed to differentiate the social use of caffeine from doping attempts. For the time being caffeine should continue to be…

    Conclusion Heart rate variability has considerable potential to assess the fluctuations in the autonomic nervous system. Here we have examined the impact of meditation – Dialogue with the Body – on heart rate variability. A relaxing effect of meditation on Heart rate variability was observed. Thus this non-invasive methodology is of substantial utility to evaluate autonomic control mechanisms in spite of an incomplete understanding of the physiological significance of HRV parameters. There was an increase in the RR interval, SDNN and SD2 on day 90 indicating an increase in heart rate variability and relaxation with a decrease in stress.…

    3) Over the past thirty years research on the effects of ergogenic aids of CHO and caffeine (CAF) during endurance exercise has been studied and, researchers have mixed answers to why the combination of the two improve exercise. The research states that combination of these two ergogenic aids improves endurance performance. CAF is absorbed quickly through the gastrointestinal tract and is metabolized in the liver which allows for elevated levels to appear within fifteen to forty minutes. The effect that CAF can have is it can cross through the blood brain barrier without difficulty.…

    Increased adrenaline causes alertness; higher heart beat, and dilated pupils. The half-life of caffeine is on average 6 hours, once the body metabolizes the caffeine through the liver. This is why it is important to limit your consumption of caffeine after noon because even after the initial effects wear off caffeine is still present in your receptors and can hinder a good nights…
