Many times when people think of exercise it is thought of in an incredibly broad sense. There is no second thought given to whether the workouts are high or low pace, to what the level of exertion is, or the fluctuation of oxygen levels. With this being said, there are others that think of exercise in a more detailed way that live and breathe it, and are educated in the way the details of exercise works. This detailed broken down way of thinking breaks down breathing, heart rate, recovery, and many other details. When breathing and oxygen are thought of, these types of exercise are classified into aerobic and anaerobic exercise. Aerobic exercise – meaning with oxygen, is an exercise that raises the body’s need for oxygen causing a higher …show more content…
When breathing during aerobic exercise the body releases carbon dioxide. As a result, during this type of exercise the body is able to expel the carbon dioxide and breathe in oxygen, resulting in the body not building up lactic acid in the muscles. Aerobic exercise has been shown (not proven) to be influential in extending life. However, this is contingent on how much exercise is done and for how long each day (Bushell, 2009). Aerobic exercise is easier to do anywhere. There are many different exercises that are able to be done at home and outside without the use of equipment, it is more convenient and allows for a better workout when there is not a requirement to go somewhere for a workout. Anaerobic exercise is defined as “without oxygen” (Merrium-Webster, 2015). This type of exercise is only tolerable by the body for a few minutes at a time and can take up to four minutes to recover. When exercising anaerobically the body is overexerting and using all of its energy at once. This causes a slower recovery and a longer healing time. The body is able to produce anaerobic exercise in bursts, but the energy consumed is more than the body is able to allow (Gastin, 2001). This is due to the intense nature of the workout causing these types of workouts to be shorter in total duration. When participating in anaerobic exercise lactic acid builds
Aerobic capacity can be defined as the ability to persist in physical activities that rely on oxygen to keep producing energy to fuel the whole body for an extended period of time. Aerobic capacity uses the aerobic energy system, a system that is used for long-term energy and has unlimited amounts. As the middles role is to align and drive their team both forward and backwards, they must have a strong aerobic base to rely on. A game of forty minutes requires a long duration of energy and almost 20% of a touch game uses the aerobic energy
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.
Anaerobic respiration is the chemical processes necessary for maintenance of life without the use of oxygen. This type of respiration occurs when there is not much oxygen left within the body for aerobic respiration to occur. Anaerobic respiration will be used when a person is running for a long time at a fast pace.
In addition a small rise in breathing rate and this is called anticipatory rise, this happens when exercising. The average reading for breaths per minute during exercise is 23-30. This shows that with more blood pumping through the body more oxygen is needed to keep the body at a sustainable rate to help our body create more energy. Our breathing rate will keep increasing until
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 first of the five components is aerobic endurance. Aerobic endurance is how the body supplies oxygen and energy during prolonged physical activity like a sport or going on a run. Some activities that aerobic endurance is used are walking/running, riding a bike, going for a swim, jumping rope and playing
The body needs more oxygen during exercise because the muscles need to produce more energy for the body to become more active. During exercise, the body’s muscles send messages to the brain that they require more oxygen. Then the brain sends signals to the diaphragm and the muscles between the ribs, which are the muscles responsible for controlling breathing, and allows them to shorten and relax more often. Clearly, an active body needs more oxygen than a body at rest. The reason for this is because of a complex chemical process in your muscles and your bloodstream.
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.
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.
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”).
Anaerobic respiration occurs during prolonged exercise as our heart and muscle use up a lot of oxygen, this prevents oxygen from being transported to the lungs quick enough. The word equation for this is Glucose---- Lactic acid and energy. I
I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.
The heart rate is a measurement of how many times the heart beats in a minute. Physically fit people tend to have a lower heart rate and during intense exercise tend to have lower rates as well. A decrease of heart rate at both rest and at fixed intensity of sub-maximal exercise [7] occurs a few months after an exercise program is begun. One’s heart rate reflects the amount of work the heart must do to meet an increase of demands of the body when engaged in activity. Heart Rate tends to increase proportionally with intensity oxygen uptake [16].
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.
The articles by Erikson et al., Gatz, Korol et al., and Draganski et al. explore the concept of increased physical activity and/or mental activity having effects on the cognitive function and development or deterioration of the brain as we age. Although I agree that physical exercise is critical in increasing cognitive function because of the health benefits it provides, as well as the increased blood flow and circulation throughout the body, I ultimately believe that a healthy brain is not achieved solely by physical exercise or mental exercise, but both. I think there is a link between physical and mental exercise, and that the combination of these two activities creates higher cognitive functioning of the mind as well as the body. The mind and body come together and meet to make an overall healthy individual.
