Exercise Effects on Cardiovascular and Respiratory Systems Mostly Accurate

“Design a poster or set of slides on the effects of exercise on cardiovascular and respiratory systems. Definition · Cardiovascular system: (1,3,4,5) o Heart and blood vessels that circulate the blood throughout your body. o Provides oxygen and nutrients to tissues and transports carbon dioxide and waste away. Maintains blood pressure while helping your body to function as it should. o Respiratory system (2) o Breathing organs (Lungs + Airways) o Helps Leverage oxygen Inhale and carbon dioxide Exhale. o Closely interacts with the cardiovascular system to deliver oxygen. Benefits of Physical Activity · Cardiovascular: o Enhances cardiac muscle, making it stronger; more efficient as a blood pump. (1, 3, 5) § Exercising regularly makes your myocardium stronger which allows your heart to pump more blood each time it beats this will raise stroke volume and lower overall workload. (1, 3) § A more efficient heart means better circulation of oxygen10 rich blood to all areas of the body, leading to improved cardiovascular function. (1, 5) § Exercise reduces resting heart rate in the long run, as the more powerful heart is able to meet the body’s demands with a lower number of beats. (3, 5) o Decreases blood pressure and cholesterol lowering the risk of heart disease. (1, 5) § Your blood lipid profile also improves as a result of exercise, with this lowering levels of LDL (or "bad" cholesterol) and increasing HDL ("good" cholesterol). (1, 5) § Regular activity decreases blood pressure by allowing arteries to stretch better and reduces the stress of blood vessels. (1, 5) § Reduced blood pressure and normalized cholesterol levels have substantial preventive impact on heart attack and stroke. (1, 5) o Increases blood vessel flexibility and flow with nitric oxide production. (3) § During exercise, nitric oxide is released to dilate blood vessels—increasing circulation. (3) § More flexible vessels can prevent plaque build-up and may decrease the risk of atherosclerosis. (3) § Better circulation, which provides muscles and heart more oxygen and nutrients asynchronously increasing the endurance. (3) o Helps to regulate blood sugar and lower risk of type 2 diabetes (3,5) Things we know § Physical exercise has a role to play, i.e. will increase insulin sensitivity which is the ability of your cells to utilise glucose more effectively (3, 5) Exercise helps lower blood sugar levels by moving glucose into muscles for energy. (3, 5) § Regular exercise lowers the risk of developing type 2 diabetes are an effective risk factor for heart disease. (3, 5) o Improves mood and counteracts depression, stress, promoting brain and cardiovascular health. (3) § Physical exercise promotes the release of endorphin, which provides an improved mood and reductions in stress. (3) § Lowering stress will also lower blood pressure and inflammation, protecting the heart. (3) Regular exercise will help in sleep and emotional balance as well which is important for long-term cardiovascular fitness. (3) o Aids in maintaining a healthy weight, reducing strain on cardiovascular health (1, 4, 5) § Physical activity helps lose weight, it has a cheap price to build muscle and maintain normal weight. (1, 4) § Weight management stresses less on the heart which decreases chances of hypertension and heart attack. (1, 5) Weight moderation also keeps cholesterol and blood sugar levels in check, so cardiovascular health is doubly protected. (4, 5) · Respiratory: o Improved the strength of lungs and breathing muscles which helps increase oxygen exchange. (2) Exercise strengthen the diaphragm and intercostals, allowing for more efficient breathing. (2) Greater respiratory muscles will allow more oxygen to go to the bloodstream and remove carbon dioxide from it. (2) o Increase (max) lung volume through improved utilization and decrease dyspnoea (2) § It increases the amount of air that can be inhaled with each breath, leading to greater total lung capacity. (2) § Improved efficiency means we can do things with less effort and less breathlessness (2) o Improves endurance and energy through improved oxygen delivery. (4) § Exercise enhances the body’s utilization of oxygen delivery, which increases endurance. (4) § Increased oxygen delivery is correlated with higher energy during day-to-day activities and exercise. (4) o It reduces the risk of respiratory sickness and aids in the comeback from lung illnesses. (2) Keep up your routine, as activity aids clearing mucous in the lungs which helps reduce infection. (2) § For people with asthma or COPD, exercise may improve lung function which is associated to better long‑term breathing. (2)”

Summary

Regular aerobic and resistance exercise strengthens the heart muscle, improves stroke volume, lowers resting heart rate, reduces blood pressure and LDL cholesterol, enhances vascular flexibility via nitric oxide, and improves insulin sensitivity, mood, and weight control. It also increases respiratory muscle strength, lung capacity, and oxygen exchange efficiency, and can aid recovery from asthma or COPD. These effects are well supported by current medical research.
