The body is composed of various systems that work together to maintain a homeostatic environment. The respiratory system and cardiovascular system in specific, are responsible for distributing respiratory gases throughout the body in attempt to maintain acid-base balance levels between the optimal range of 7.35 and 7.45. Exercise imposes physiological strains on the body such as oxygen depletion and increase carbon dioxide concentrations, which alter the pH balance. This homeostatic change stimulates various responses within these two systems to neutralize its effects. Exercise training however, can positively influence the capacity of cardiovascular and respiratory systems to tolerate increasing levels of intensity with less physiological effort thus improving their efficiency. Inflammatory conditions such as Chronic Obstructive Pulmonary Disorder (COPD) and Interstitial Lung Disease (ILD) are shown to stifle efficient pulmonary ventilation and detriment one’s ability to cope with exercise. Although evidence supporting the benefits of pulmonary rehabilitation within ILD patients is limited, functional capacity and psychological wellbeing have been shown to improve immediately following the rehabilitative programs. Pulmonary rehabilitative programs are based on the pulmonary and circulatory improvements associated with exercise to help such discomforting conditions and guide further research.
The respiratory system contributes to homeostasis by managing the gaseous
Homeostasis can be defined as the balance maintained by the body through negative-feedback to regulate internal conditions within a normal range promoting sustained good health (Seeley, 2006). Exercising initiates a process that propels the body out of its normal parameters, therefore triggering negative-feedback loops with the aim of bringing the internal balance back into homeostasis. Increased energy intensities created through exercise influence heart rate (bpm), respiration and perspiration levels. Each system strives to assist in generating sufficient energy to continue exercising and sustain homeostasis (Sherwood, 2015). Concluding that the body has to work harder in order to maintain the correct internal environment during exercising, it is reasonable to suggest that an increase in heart and respiration rates, as well as
Two protocols were administered; the first group only did the exercise without any help from the NIV. The patients were asked to lift containers with weights in them, ranging from 0.5 to 5 kg during a five minute period. Their arms had to be extended and move them from a waist high shelf to one above their head. The second group performed the same procedure, but had assistance from the BiPAP ventilator. The settings were an IPAP of 10 cmH2O and an EPAP of 4 cmH2O using a facemask. The COPD patients had to become accustomed to
It is a well-kenned fact that exercise is very propitious to the body’s overall health. Exercise has been shown to enhance the circulation of blood throughout the body, relinquish solicitousness, boost self-esteem, and ultimately is utilized as a treatment for noetic illnesses.
The field of exercise science is facilitating and understanding of links between fitness exercise, diet and health. There have been many studies that show how exercise and the human body interact. My main interest is being a physical therapy and showing how exercise can help the human body when used effectively. If you over exert yourself, it can cause your immune system not to function correctly. In this exploratory essay a comparison of a journal article and news article to find out that intense exercise can cause the immune system not to recover after exercise.
Exercising stimulates Vasodilation and Vasoconstriction to facilitate the oxygen delivered to the muscles. It also keeps the blood vessels healthy and stops the accumulation of cholesterol and harmful substances. It can also help on warming up and cooling down of the
Engaging in regular exercises is one of the ways one can cope with COPD. Exercise improves the breathing and promotes overall health of the person.

While most physical therapists will not solely work in a cardiopulmonary rehabilitation position, all settings of physical therapy frequently treat patients suffering from co-morbidities in addition to the condition that they are prescribed for our care.1 Recognizing and understanding these co-morbidities is important to provide the most effective care to the patient while also decreasing the risk of predisposition to other health conditions.2,3 This is especially important when physical therapists are in a position of providing primary care by seeing patients under a direct access model.4 There are also times when multiple co-morbidities occur simultaneously which must be considered in a plan of care.5 It is important that the physical therapist always screens for co-morbidities, but essentially important when there is the presence of one co-morbidity that is commonly associated with another co-morbidity.3 The recognition of multiple conditions is critical because of the potential interaction that can occur between the different conditions. The presence of one or more conditions can also have a profound impact on treatment that they receive both through surgical and rehabilitative interventions. Co-morbidities can fall under multiple areas and body systems that each affect the patient in different ways. Respiratory and cardiovascular systems are particularly interrelated and can play a vital role in guiding the future
Throughout this essay I will be discussing the effects that COPD has on the body and give you exercises and advice provided by physiotherapists to help people cope with the disease. Although COPD cannot be cured there has been research into COPD to try and help patients with this disease manage it. By using a disease-oriented approach the most important part is that it increases quality of care given to patients with COPD.
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.
Patients who have COPD combined with CHF might find exercise a bit challenging. This is because CHF is an exacerbation of COPD. Typically these diseases react on their own with similar signs and symptoms. COPD is a long term chronic obstructed pulmonary disease, which causes decreased expiratory flow rates. It is known as the third leading cause of deaths in the US. It is brought on by lifestyle, such as smoking which is the number one cause of COPD, even those that have never smoked but have been exposed to secondary smoking are at risk for this disease. Other factors that may contribute is place of residence and occupation, due to the exposure of pollutions and other harmful chemicals in the residence or place of
Currently, there is still lack of comparable information about access to and utilization of pulmonary rehabilitation and oxygen therapy. There has been concern that rehabilitation might worsen exercise hypoxaemia. In contrast, the correction of hypoxaemia during exercise might lead to more effective rehabilitation by permitting a greater degree of training than would otherwise be possible. Options for improving data about these interventions are discussed in a recent report ‘Monitoring pulmonary rehabilitation and long-term oxygen therapy for people with chronic obstructive pulmonary disease (COPD) in Australia’ – a discussion paper
Exercise represents a physical stress that challenges homeostasis. Its undoubted beneficial effect on the health of the body has been underlined in numerous scientific studies. However, exercise in excess can be deleterious to certain organs and systems of the body. Exercise is a stress situation for which the body must find a new dynamic equilibrium and this requires. among other things, adaptative responses of the hormonal system.
INTRODUCTION: High-Intensity Interval Training (HIIT) is known as one method to treat Cardiovascular Diseases (CD), such as Coronary Arterial Disease (CAD) and Heart Failure (HF), due to its potential to improve cardio respiratory fitness (1, 15). This exercise format is characterized as aerobic exercise performed in a high intensity - usually controlled by either maximum oxygen uptake or maximum heart rate – with active and low intensity. Performing exercise in high intensities mixed with active rest allows patients to tolerate a higher effort before they become tired. Heart failure patients present a diminished exercise capacity, due to a smaller Ejection Fraction (EF), which tells us how well the heart pumps blood to body. To these patients, High-Intensity Interval Training has been reported for improving Systolic Function due to the increased effort in which the heart is working (16). The necessity to provide nutrients through circulation during exercise leads to an increased contractility and consequently LV Remodeling (15). Coronary Arterial Disease Patients have a decreased blood flow to the myocardial tissue due to an obstruction inside the coronary arteries. HIIT increases the arteriovenous O2 difference, which means there is an elevated consumption of oxygen by the tissues as result of a higher stroke volume. All those benefits have been shown in the literature, but most of the studies present data with short-term interventions. A few studies discuss the benefits
Mammals consume oxygen and produce carbon dioxide as part of their metabolism process in order to maintain body functions. This occurs at all times, both rest and during intense work, within mammals. During times of greater work, skeletal muscles work harder than they do at rest. This in turn increases their metabolic rate and results in a greater demand for oxygen. It has been proposed that fitness training has a positive effect on both the cardiovascular and respiratory systems, which effect the maximum oxygen consumption rate during intense exercise periods. I hypothesize that individuals who aerobically exercise a minimum of at least 7 hours per week will have increased fitness, which will maximize their overall metabolic rates and give them higher VO2 max and VCO2 max values than individuals who do not have increased fitness. Ten males having different fitness levels were put on stationary bikes at increasing levels until exhaustion and VO2-max and VCO2-max was then measured from each individual. It was found that there was a slight upward trend between fitness-VO2max and fitness-VCO2max, although this trend was not statistically significant when represented by the T-test values through statistical analysis. Further experiments should be done in the future to verify a statistically significant correlation.
