The Importance of Oxygen when Exercising

Exercise and physical activity deliver oxygen and nutrients to your tissues and help your cardiovascular system work more efficiently.

Exercise: The American Heart Association (AHA, 2014) recommends exercising at least 30 minutes of moderate-intensity aerobic activity at least 5 days per week for a total of 150

Exercise increases the use of energy by your muscles, which activates a series of reactions to create new energy to keep exercising and maintain homeostasis. The first reaction that occurs is an increase in your breathing rate. Energy creation requires significant oxygen. The only way to provide the necessary oxygen is to increase the speed at which your respiratory system is introducing it into your bloodstream. The harder you exercise, the more energy is used, resulting in your body increasing your breathing rate even more to maintain adequate energy levels for balance.

These components include aerobic power, which can be typically described as VO2 max, this is the maximal amount of oxygen the body can take in and use efficiently. The amount of oxygen taken in can be influenced greatly by the cardiovascular systems ability to deliver oxygenated blood to exercising muscles, the lungs ability to oxygenate the blood and the muscles ability to use the oxygen and extract it for sustained contractions. Disease and inactivity therefore can impair or inhibit these factors consequently reducing a persons ability to function.

The lungs have a huge blood supply and a huge surface area so they are very effective at getting oxygen out of the air. They are also in charge of getting rid of the carbon dioxide excess and some of the excess water as water vapour. It is the lungs job to get the oxygen and the heart has to pump it around the rest of the body. Energy metabolism; when people are exercising their muscles are contracting and they are using more energy so they will need more oxygen getting to the muscles and my heart

Capillarisation increases during long term exercise. Long-term aerobic exercise improves the elasticity of your blood vessels, or the ability of your vessels to expand and contract. The improved elasticity delivers more oxygen and glucose to your muscles at a faster rate. The number of capillaries in your working muscles also increases as an adaptation to long-term aerobic exercise.

What limits the speed and stamina of most endurance athletes is the ability of their heart and lungs to deliver oxygen at a steady rate

Since the ATP vitality utilized by your muscles is produced with the guide of oxygen, it takes after that an expansion in exercise force will bring about an increment in muscular oxygen requests. Accordingly, more intense exercise relates to an expanded VO2. This is the reason that you're breathing gets continuously quicker and more profound as your exercise force expands, your body is attempting to give more oxygen to your working muscles with the goal that they can produce enough ATP vitality to keep you

A person's cardiovascular system is a very important part of fitness and one's overall health. Here are a few of the best exercises; walking running, cycling, rowing, swimming. Research suggests at least 150 minutes per week, a minimum of 30 minutes per day, five times a day a week. A few exercises that are best are, climbing, playing sports, and running is also some of the most common and affordable. At least 25 minutes of vigorous aerobic activity at least or a combination of moderate and aerobic activity are some of the best options to benefit your cardiovascular system.

When you exercise your muscles break down and this allows them to grow back stronger than they were before. When you exercise your body uses your skeletal, muscular and respiratory system.

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

The purpose of this lab was to understand how mammalian pulmonary and circulatory systems increase the delivery of oxygen to cells during exercise. The systems were examined by measuring pulse, vital capacity, ventilation rate, and the blood pressure at rest and immediately following short exercise. From these observations we measured the height, weight, body mass index (BMI) and smoking status in order to determine what may affect exercise (Barrilleaux, 2014).

• Do moderate-intensity physical activity for at least 30 minutes on 5 or more days of the week, or as much as told by your health care provider.

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.

Physical fitness has two main classifications-performance related and health related. People have different performance related requirements in accordance with their occupation but all people have the same health related requirements (The World). Then there are two types of exercise that helps tone a person’s body while increasing its endurance. These are aerobic and anaerobic. Aerobic exercise is exercise that uses the muscles and bones. Cardio activities are a good example of this, such as running or biking. This type of exercise increases the strength of a person’s heart and boosts their lung capacity. Anaerobic exercise is an intense but short amount of exercise (Payment). Since it is only for a brief amount of time, it does not require the amount of oxygen aerobic exercise does. Instead it uses glycogen which comes from the sugar in a person’s blood. An example of this exercise is weight lifting or sprinting. A person’s requires both anaerobic and aerobic exercise for good health. Simply doing a cardio work out is not healthy, and for a person to see real results there must be some activity like weight lifting (“Anaerobic”).
