Task 2b
Taking Measurements of the Respiratory System
Aim: To measure the effect of exercise on the respiratory system.
Prediction: I think that during exercise the breathing rate will significantly increase from the resting breathing rate, then once exercise has stopped the breathing rate will gradually decrease over a few minutes till it returns back to the resting breathing rate.
(Justification) During exercise the use of the muscles is more intense meaning their supply of oxygen is needed in larger quantities. Oxygen is obtained in the body through respiration before being transported in the blood via the arteries to where it is required in the various cells of muscles across the body. Additionally, during exercise the body is producing

I also concluded that the breathing rate did gradually return to resting breathing rate from working breathing rate during the recovery time after the exercise have stopped. …show more content…
There were obviously differences in the specific number of breaths each participant at the different stages of the experiment but this is just due to the different levels of fitness that each of the participants will have. Also the different levels of fitness will also effect other factors e.g. a fitter person may have a quicker recovery rate or if the participant has poor fitness they may have a higher resting breathing rate than a fitter participant. When using the secondary data however, it is important that the accuracy of it when comparing it to our own data is reliable. For the secondary data we used, the participants were of a similar age and roughly the same fitness levels and we used the same methods and timings to collect the data. However one major issue is that our group and the other group did different exercise for different lengths of time; our group did sprints intermittently for around 5 minutes, whereas the other group ran at a steady pace for 3 minutes – this may make the results less accurate and reliable as it is altering one of the control variable and is something that needs to be considered if we carry out the
For further investigation, a larger sample size should be used, along with repeating the experiment on several different days to minimise the effect of random errors on each subject’s specific result. Reference List: BBC 2014, Respiration, BBC, accessed 1 September 2015,.
Respiratory assessment is a significant aspect of nursing practice. According to the National Institute for Health and Care Excellence, respiratory rate is the best indicator of an ill patient and it is the first observation that will demonstrate a problem or deterioration in condition (Philip, Richardson, & Cohen, 2013). When a respiratory assessment performed effectively on a patient, it can result in upholding patient’s comfort and independence in progress of symptom management. Studies have acknowledged that in spite of the importance of the respiratory rate (RR) it is documented rarely than the other vital signs in the hospital settings (Parkes, 2011). This essay will highlight the importance of respiratory assessment and discuss why nurses
In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.

Red blood cells deliver the oxygen to the muscles and organs of the body.

The assumed etiology of exercise induced asthma has two basic theories. One theory concerns the water content of the air that is being breathed in to the lungs (dry) and the other theory concern...
After the subjects submerged their faces into 15 and 5 degree water, their heart rates decreased. When the resting heart rate was recorded, it showed a regular heart rate. As shown on the graph, once the subject held their breath, the heart rate increased. It is expected for the heart rate to decrease during apnea because less oxygen is being used meaning your heart is doing less work. Once you breathe again, the heart rate will increase due to homeostasis.
•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.
These results make sense because the heart beats faster in order to keep the body’s cells well equipped with oxygen. For one to continue exercising for long amounts of time, cells need to create ATP in order to use energy. Oxygen must be present for the process of creating ATP, which not only explains why higher respiratory rates occur during exercise but also faster heart rates. When the heart is beating rapidly, it is distributes oxygenated blood as fast as the body n...
Hypothesis – I predict that as the intensity increases during exercise the heart rate will also increase. I think this because your body needs oxygen in order to efficiently break down glucose and process it into your cells. As the exercise intensifies, you need more energy and therefore more oxygen. Your blood carries oxygen from the lungs to your muscles. To keep up with these increased oxygen needs, you have to have more blood going to your muscles. As a result, your heart pumps faster, sending more oxygenated blood to your muscles per second.
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
Investigating the Effect of Exercise on the Heart Rate Introduction For it's size the heart has the huge capacity of pumping large amounts of blood, in the average adult's heart beats 60 to 100 times a minute, pumps between 70ml and 100ml of blood with each beat, circulates 5 to 6 litres of blood around the body per minute and about 13 litres of blood per minute during vigorous exercise. The heart will beat more then 2.5 billion times during an average lifetime. This investigation will be looking at the effect of exercise on the heart rate. Aim The aim of this investigation is to find out how exercise affects the heart rate, using research & experimenting on changes and increases in the heart rate using exercise. Research â— The heart The normal heart is a strong, hardworking pump made of muscle tissue.
Aerobic exercise involves improving the cardiovascular system. It increases the efficiency with which the body is able to utilize oxygen (Dintiman, Stone, Pennington, & Davis, 1984). In other words, aerobic exercise means that continuous and large amounts of oxygen are needed to get in order to generate the amount of energy needed to complete the workout. The most common type of aerobic exercise is long-distance running, or jogging. While running, the body requires large amounts of energy in order for the body to sustain energy. “During prolonged exercise, most of the energy is aerobic, derived from the oxidation of carbohydrates and fats” (Getchell, 1976).
There are 2 types of breathing, costal and diaphragmatic breathing (Berman, 2015). Costal refers to the intercostal and accessory muscles while diaphragmatic refers to breathing using your diaphragm (Berman, 2015).It is important to understand the two different types of breathing because it is vital in the assessment of the patient. For example, if a patient is suing their accessory muscles to aid in breathing then we can safely assume that they are having breathing problems and use a focused assessment of their respiration. Assessing respiration is fairly straightforward. The patient’s respiration rate can be affected by anxiety so a useful to avoid this is to check pulse first and after you have finished that, while still holding their pulse point, check their respiration rate. Inconspicuous assessment avoids the patient changing their breathing because they know they are being assessed which patients can sometimes do subconsciously. Through textbooks and practical classes I have learned what to be aware of while assessing a patient’s respiratory rate. For example; their normal breathing pattern, if and how their health problems are affecting their breathing, any medications that could affect their respiratory rate and also the rate, depth, rhythm and quality of their breathing (Berman, 2015). The only problem I found while assessing respiration rate was I thought it seemed a bit invasive looking at the
