I. Introduction
In this experiment, we investigate the correlation between exercise, heart rate, and oxygen saturation. The human body depends on the oxygen transport by hemoglobin. Healthy adults have a normal oxygen saturation level between 94-99%. (Timmings, 2014). This means that the majority of oxygen is bound to hemoglobin. On the other hand, adults with respiratory and cardiac problems tend to have lower oxygen saturation level. Therefore, Haymond (2006) stated that oxygen saturation- the percentage of hemoglobin bounded to oxygen- is a clear indicator of a person’s cardio-respiratory status expressed as SpO2.

While oxygen saturation levels are fairly constant, this value may fluctuate during exercise due to the increase need for oxygen. This is because the body has to work harder to keep the oxygen saturation levels up so that it can keep on functioning. To allow more blood to flow out of the heart, arterioles expand and ventricles contract harder. As the heart beats faster, blood flows faster, decreasing the amount of time oxygen has to enter the blood stream. Wonderly (2011) explains that this makes it harder for blood to stay oxygenated. During exercise,

This instrument shines a red light through the finger and calculates the percentage of blood saturation by measuring the amount of light that passed through the fingertip and surmising how much has been absorbed by the oxygen in the blood. According to Pulmolink (2015), the fingertip pulse oximeter detects minor changes in absorption as the blood is pumped past the measurement site. Weak pulses can give inaccurate measurements. ”Your pulse oximeter measurement naturally lowers during exercise because of changes that occur in oxygen-binding properties of red blood cells. Specific measurements vary depending on your health situation and exercise intensity” (Carmichael,
Also during exercise the amount of glucose produced by cells increases due the requirement for more ATP from working muscles, than from those at rest. The influx of glucose to the bloodstream after consuming a meal or snack shows how the components of the glucose homeostasis system work together to re-establish normal blood glucose concentration. The rainbow rage is a long and tiresome race, therefore, blood glucose levels may run low due to their depletion.
1. Describe the relationship between intrapulmonary pressure, atmospheric pressure, and air flow during normal inspiration and expiration, referring to Boyle’s law. - Boyles law states that as the pressure of gas increases then the volume of gas decreases. Which is how intrapulmonary and atmospheric pressure are connected to one another. Intrapulmonary pressure is lower while undergoing inspiration and higher than atmospheric pressure during the time of expiration.
For the boys, there was an increase of 3.0 points from year 1 to year 2, but a higher increase of over 16 points from year 2 to year 3. However, for girls, there was higher increase between the first two years of about 8 points and 10 points from year 2 to year 3. This change is consistent because maximal oxygen uptake increases linearly in children, where girls usually reach their peak around 12 or 13 years old while boys continue until about the age of
Spirometry is used periodically to assess whether breathing problems are under control and how well your medications are working. A nebulizer
P6 review physiological data collected, describing the effects of exercise on the musculoskeletal, cardiovascular, respiratory and energy systems Cooper Run The first test I did was the Cooper twelve minute test. This tests ones endurance. Advantages of this test is that you don’t need a lot of equipment, it is simple to set up and do so this won’t take up too much time. More than one person can do the test and one time.
Computerized tomography (CT) scan combines X-ray images taken from many different directions into cross-sectional views of internal organs. CT scans can provide detailed information about the structures within the heart and lungs. 4.3.2 Lab tests. A test using blood from an artery in your wrist can measure oxygen level.
In this experiment, we will focus on how exercise, in particular, affects the cardiopulmonary physiology of boys across different body mass indexes. Exercise places strenuous activity on the human body. When an individual exercise, the blood flow must level up to the demands being made on the individual’s muscles, heart, and lungs. Blood flow increases so that the blood does not clot
For this reason we predict the aldosterone levels should rise with increased physical activity, due to the increased fluid and
Some time ago, oxygen therapy and steroid treatment were considered dangerous for people with COPD. Exercise was discouraged because it put a strain on the heart. A COPD diagnosis is typically confirmed with spirometer, which measures someone’s lung function. Spirometer is the most common way Doctors evaluate the level of airflow obstruction.
I allocated 2 minutes for each exercise with 2 minute breaks in between. After each exercise I had them blow into the spirometer again. I recorded the before and after for each participant after each
Macke the people jump with a tie for 2 minutes, without talking. Then after the 2 minutes making the activity, take 2 other minutes to breath and count how many inhalation and exhalation the person have and take note Make that the people stand and breathe for 2 minutes. Put all the results in the data collection table and then compare the breaths of the different people Results: Table 1: Ventilation rate Activity Time Person 1 Person 2 Person 3 Person 4 Lying down 2 min 17 31 25
At the dynamic exercise onset, oxygen consumption starts to increase, continues to rise through the initial time of sustained exercise, but then flattens as transport and uptake are increased adequately so that the consumption is matched to the demand (Laughlin S245). In the recovery stage, oxygen uptake will eventually surpass oxygen supply to a point at which oxygen consumption rate exceeds aerobic capacity resulting in oxygen
This ability to extract and use the oxygen will determine the body’s ability to perform aerobic exercise.
At rest, the gut receives over half of all organ blood flow, but during exercise, blood flow to the gut can drop to less than 20% of this resting value. Lack of blood flow to the gut during digestion can lead to increased intestinal
This will be done using a respirometer which will measure the rate of oxygen usage. The change in volume recorded by the respirometer pipette will be an indication of this. BACKGROUND INFORMATION
