Smoking affects the lungs by interfering the process on which dust particles or soot is removed from the bronchial tubes and lungs. A higher chance of clogging and plugging in the vessels is present which reduces the amount of blood going to the heart. The book The Athletes Body states, “...However, serious competitors tend to stay away from cigarettes at least those of the tobacco variety” (Sprague and Jares). Smoking tobacco does not have the same effect as the other drugs and therefore it is not as common to be found in professional athletes. It does not provide that feeling of rush or happiness nor does it improve athletic performance.

Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

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.

36 of them were smokers who had been smoking for not less than 5 years and smoked up to 15 cigarettes every day. On the other hand, the 40 vapers were ex-smokers who had quit and had been vaping for more than one month prior to the study. During the study the vapers and smokers were placed in separate rooms. The smokers were given one cigarette each while the vapers smoked the same e-liquid, with 7mg nicotine content, and were then asked to vape for 7 minutes. The research team, led by cardiologist Dr. Konstantinos E Farsalinos, measured and recorded a number of heart function before and after vaping and smoking. They noted that the heart functions, in smokers, changed immediately after smoking. Also, the team determined that vaping did not have any adverse effects on the myocardial functions.

Age is important as the target for reduction in mortality from CHD, stroke and related disorders of 40% of the year 2010, established in Saving Lives: Our Healthier Nation (DoH 1999), referred to the under 75 age group. The key areas identified for intervention in the national service framework are: reducing smoking, promoting healthy eating, promoting physical activity and reducing obesity, although several other factors are known to contribute to the development of CHD. Smoking has long been known to be a factor in the development of CHD. According to Smeltzer and Bare (2000), smoking decreases blood flow to the extremities and increases heart rate and pressure via stimulation of the sympathetic nervous system, causing vasoconstriction. In addition, it raises the chances of clot formation by increasing the aggregation of platelets. Campbell (2006) suggests that the toxic components of cigarette smoke damage the endothelial lining of the blood vessels, which may initiate the development of atherosclerosis. Because carbon dioxide from the cigarette burns readily with haemoglobin, it deprives oxygen of

The tar, which is found in the cigarette smoke, irritates the air passage and Carbon dioxide then reduces the ability of blood to carry oxygen through the bloodstream. I predict that the non-smokers heart rate should be smaller during exercise as they have a healthier more effective heart. Oxygen is easily pumped around the body this reduces the amount of work that the heart has to do therefore decreasing the pulse rate. Plan: = ==

As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.

The controlled variable included the exercise bike and heart rate monitor. There are several limitations, systematic and random errors that should be considered when interpreting these results. (4) The controlled variables were not tested before this experiment to see if they were working and reliable. Figure 2 heart rate was quite inconsistent and did not follow the pattern of the other results, which maybe suggest a random error with the heat rate monitor. A systematic error could include the fitness of the participants. One of the test subjects is an endurance athlete and the other does not compete in any sport. This would affect the results because for the endurance-trained athlete, from their training they increase their cardiac output results from a substantial increase in maximal stroke volume. In untrained persons, cardiac output increases in response to exercise primarily by an increase in heart rate. The endurance-trained athlete does so mainly by an increase in stroke volume. Simply meaning that although both participants are doing the same cadence and length the endurance athletes skewers the results by already having an increased rate in stroke volume. Another systematic error may include the rate of perceived effort. For the most accurate results, the measured maximum heart rate would be necessary to give an accurate cadence to ride at.

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

The effects of heart rate on differing durations of exercise were studied in this experiment. For people, heart rate tends to increase as they perform physical exercises. The amount of beats per minute gradually increases as people perform physical activities. Heart rates taken before exercise are relatively low, and heart rates taken one minute after exercise increase significantly. Heart rates slowly begin to decrease after they are taken two minutes and three minutes after performing the step test, which is to be expected. The rates of intensity throughout exercise relates with changes in heart rate throughout the step test performed in the experiment (Karvonen 2012). The age of the participants affected the experiment, since the heart rate during physical exercise, in this case the step test, is affected by age (Tulppo 1998).

The heart rate is a measurement of how many times the heart beats in a minute. Physically fit people tend to have a lower heart rate and during intense exercise tend to have lower rates as well. A decrease of heart rate at both rest and at fixed intensity of sub-maximal exercise [7] occurs a few months after an exercise program is begun. One’s heart rate reflects the amount of work the heart must do to meet an increase of demands of the body when engaged in activity. Heart Rate tends to increase proportionally with intensity oxygen uptake [16].

Good physical health is a vital part of the well-being of every person. A major component of our physical health is “Cardiovascular fitness”. Cardiovascular fitness is the ability of the heart and lungs to provide oxygen to the muscles for activity of an extended duration. If we have a good level of cardio-vascular fitness we are able to sustain activity for a reasonable period of time and not fatigue easily. This can give individuals a variety of health benefits and allow more regular and enjoyable activity to be participated in. This research report will examine my results of cardio-vascular fitness tests and weekly physical activity events, which
