Abstract:. The Consequence Of Exercising On Respiration

Being knowledgeable about the heart is very important, especially if one is an athlete. This experiment is significant, because it can tell us how important it is for one to keep their heart healthy. It will also tell us how playing a sport can benefit one’s health and the well being of their heart. Our hypothesis says, if the athleticism of a person increases, then the heart rate recovery time will decrease when heart rate recovery in a function of athleticism. The purpose of this project is to see which type of athlete, or non-athlete has the best heart function.

Two mechanisms that increase oxygen consumption during physical activity, is the increased total quantity of blood pumped by the heart and the ability to use the already existing large quantities of oxygen carried by the blood6. An increased total quantity of blood pumped by the heart, also known as cardiac output, at maximum has a direct correlation with VO2max6. A near proportionate increase in maximum cardiac output increases in VO2max with in endurance trained and un-trained individuals has been distingushed6. This relationship suggests with physical activity VO2max is increased through an increase of cardiac output.

It was observed that the average systolic blood pressure did increase going from at rest to just after exercise (118 mmHg to 179.5 mmHg; Table 1.), however there was no significant difference between the two with a p-value of 0.063 (Table 2.). The average diastolic blood pressure increased slightly from 71.5 mmHg at rest to 79 mmHg after exercise (Table 1.); however, there was also no significant difference between the two with a p-value of 0.468 (Table 2.). The average HR between the at rest and just after exercise recordings also showed no significant difference (p-value = 0.056; Table 2.), however there was a general increase from 64.5 bpm to 80.5 bpm (Table 1.).

This supports our hypothesis that exercise increases heart rate. A couple of outliers in the data include points Red(50,144) and Blue(10,96). at these points the heart rate decreases and this would be caused by random error. We are unsure of why this changed and this change could be caused by changes in environment or in the experiment that could not be seen by the eye. Systematic errors would include not allowing for full time for the heart to go back to resting rate, not measuring the heart rate before exercises, interruptions from other people causing a stop between exercising, not having a constant exercise the full time, and many others. One problem in this experiment was that many things can increase heart rate such as talking or the feeling of excitement, and of these things could have also affected our data. It is possible that in the future this experiment can be done again using other factors to prove increased heart rate. Our independent variable was time the dependent variable was heart rate and our constants included the 1 minute rests and the amount of stairs climbed. We can conclude that our hypothesis is supported by the data. If you exercise for longer periods of time, then your heart rate will

Figure 1 shows that the systolic and diastolic pressure while the subject was sitting down, 119/64, is lower than that of the other body positions and exercise. Standing showed the second lowest systolic and diastolic pressure, 121/83. Lying down showed a slightly higher blood pressure of 123/84. The highest blood pressure, 133/94, was measured when the subject had just completed some physical activity. Figure 2 and 3 display, respectively, the difference between heart contractions at rest and after exercise, as illustrated by the greater number of contractions following exercise in the same amount of time compared to resting conditions. In addition to displaying the interval lengths for three sequential beats from Figures 2 and 3, Table 1 also includes the heart rate for before and post exercise, 102 bpm and 132 bpm, respectively. Figure 4 shows similar

Person X’s heart and ventilation rate was normal before the test because they had not begun exercising and were at a resting rate. The reason their heart and ventilation

Method and results - The study was compiled of seven female students from the University of Huddersfield. For the exercise a step was used, a polar heart rate monitor was used for each participant with an independent assessor timing the participants, and recording the readings. Results of the study showed there was an increase in heart rate when performing mild exercise.

Many people are not getting adequate amounts of exercise and it is costing grave health problems such as diabetes and obesity. There has been an on-going, major concern in the medical field about the relationship of exercise and cardiorespiratory health and to better understand this correlation, this study analyzes the effect that exercise has on heart rate, stroke volume, total peripheral resistance, and oxygen consumption. I hypothesize that those who regularly exercise will overall have lower heart rates, increased stroke volume, lower total peripheral resistance, and higher oxygen consumption. To test my hypothesis, two groups were obtained: active, those who exercised more than seven hours a week, and inactive, those who did not exercise at all. Test subjects were asked to exercise on a bicycle ergometer until exhaustion as intensity increased every minute. In this experiment, both active and inactive groups observed an increase in heart rate, stroke volume, and oxygen consumption and a decrease in total peripheral resistance as time progressed. Overall, active individuals had lower heart rates, larger stroke volumes, and lower total peripheral resistance compared to inactive individuals. Surprisingly at rest, both groups were shown to have similar oxygen consumption rates, but at peak, the rate of the active group was much higher. Our results indicate a strong association between regular exercise and cardiorespiratory variables which stresses the importance

Every living organism is composed of cells. Cells consume Oxygen (O2) and produce Carbone dioxide (CO2). The respiratory system has for main function to provide the Oxygen (O2) and dispose of the Carbon dioxide (CO2) produce by the cells through the process of respiration. During exercise the demand of Oxygen (O2) and the production of Carbon dioxide (CO2) raises which affect the respiratory system. This essay will discuss the respiratory system and how it is affected by exercise (Tortora, G., Grabowski, S.,1996).

The experiment was made to test the Acute Respiratory Responses to exercise using the rowing machine once again but this time with a fitness increasing exercise which is perfect for this type of experiment. This was performed by two people, me and another person and the results were discovered then collected and recorded and then put into a table.

The main point of this report was to determine if pulmonary function was a limiting factor in regards to reaching V˙O2 peak [maximal aerobic capacity]. There were thirty-two Sunshine Coast University students that were tested over the two-week period of class. The first session was to figure out the students V˙O2 peak by participating in increasing high intensity exercise. Whereas, the second class was more to do with discovering pulmonary function and measuring forced vital capacity [FVC] and forced expired volume [FEV]. Overall, the results had proven that overall lung function was not a primary limiting factor- even though there was a positive correlation in determining V˙O2 max.

Physiological responses to aerobic training include lower resting heart rate which means increased efficiency of the cardiovascular system & faster recovery; increased heart stroke volume per beat, by way of more full left ventricle during diastole; increased

Men and women ages 15 to 30 experience physiological differences and similarities of the cardiovascular, respiratory, and musculoskeletal systems. There are many physiological differences between gender including height, weight, body composition, hormones, bone structure, and lung capacity. These changes play a role during exercise as the body systems undergoes specific adaptations to meet the demand of the active muscles. The differences and similarities discussed in the following paragraphs are significant when designing an exercise program.

Lima, Forjaz, Silva, Menese, Sliva, and Ritti-Dias published an article in 2011, that focused on the acute effect of resistance exercise intensity in cardiac autonomic modulation after exercise. During the study, participants completed three sets of 12, 9 and 6 repetitions, for five different exercises each session. They concluded that the more vigorous the exercise, the better the cardiac sympathovagal balance would be. This means that Lima et al. (2011) have provided evidence to support that with resistance training, primarily of the upper body, helps to maintain a healthy, constant heart rate. Could these upper body resistance exercise produce any additional
