Exercise Physiology: Chapter 11 – Adaptions to Aerobic and Anaerobic Training
➢ Overview o During a single bout of aerobic exercise → the human body precisely adjusts its cardiovascular and respiratory function to meet the energy and oxygen demands of actively contracting muscle. o When these systems are challenged repeatedly, as happens with regular exercise training, they adapt in ways that allow the body to improve O2max and overall endurance performance. o Aerobic training
• Also known as cardiorespiratory endurance training
• It improves cardiac function and peripheral blood flow and enhances the capacity of the muscle fibers to generate greater amounts of adenosine triphosphate (ATP). o Anaerobic training
• Improves anaerobic

• Anaerobic training increases the ATP-PCr and glycolytic enzymes but has no effect on the oxidative enzymes
• Aerobic training increases the oxidative enzymes but has little effect on the ATP-PCr or glycolytic
The data collected during this experiment has shown that a relationship likely exists between the rate of muscle fatigue and the time spent performing vigorous exercise prior to the set of repetitive movements. This is likely due to a build-up of lactic acid and lactate as a result of anaerobic respiration occurring to provide energy for the muscle cell’s movement. As the pH of the cell would have been lowered, the enzymes necessary in the reactions would likely not be working in their optimum pH range, slowing the respiration reactions and providing an explanation to why the average number of repetitions decreased as the prior amount of exercise increased.
•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.
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.
Heart rate is an indicator to demonstrate the intensity and duration of exercise. The aerobic system falls under the aerobic threshold. The aerobic threshold is “the heart rate above which you gain aerobic fitness, at 60% of our MHR.” (Bbc.co.uk, 2018). Towards the end of the Aquathon the aerobic system can no longer keep with the intensity, so the anaerobic threshold begins in the last few minutes of exercise. The anaerobic threshold “is the heart rate above which you gain anaerobic fitness. You cross your anaerobic threshold at 80% of your MHR.” (Bbc.co.uk, 2018). The anaerobic systems function without the use of oxygen. “They burn through ATP and then turn to anaerobic glycolysis, using glucose and glycogen for fuel with a by-product of lactate.” (Verywell Fit, 2018). When working anaerobically it creates oxygen debt and can only continue to keep working for a few minutes. Oxygen Debt is the oxygen consumption post exercise to replenish creatine

“Accept the challenge so that you can feel exhilaration of victory”. This quote was said by George S. Patton is discussion the important role that Athletic trainer should work and work until they win. Who are we are highly qualified multi skilled health care professionals. Also Athletic trainer prevent diagnosis treatment and rehabilitation of emergent acute or chronic injuries. Were also known for being high qualified multi skilled health care professional. Being and athletic trainer is a great and hardworking career. That involves meeting new people, dealing with different challenge each day, Also it has moderate schooling.

When the aerobic organisms in the body consume all the oxygen present, anaerobic organisms from the digestive system begin to multiply. They consume macromolecules (proteins, carbohydrates, lipids) and form acids and gases in the p...
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...
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 into your muscles. As a result, your heart pumps faster, sending more oxygenated blood to your muscles per second. Aim-
Firstly, it is highly effective for prevention and treatment of many common diseases and longevity. Strength training can improve muscle strength and endurance, make it easier to do daily activities, slow disease that related declines in muscle strength, and provide stability to joints. Stability exercises may help reduce the risk of falls. Such as heart disease. Mayo Clinic Staff said a routine of regular cardio can improve heart health. Recent studies have shown that break training is often tolerated well in people with heart disease, and it can produce significant benefits, (2015). It also allows the system of organs within the body to work better, especially the organ systems associated with the breathing and heart. According to an article in the journal "Circulation" wrote by Patrick Dale, (2014). When everyone begins to exercise, blood is shunted to muscles from other areas of body, including their gut. The temperature of blood increases and the blood vessels near skin expand to promote total body cooling. It increases the density of bone in the body, and stimulates lung function makes the lungs
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).
All over the world, it is believed that physical exercises help people achieve wellness. Physical exercise not only encourages physical wellness but also have a significant impact on mental stability and health. Although such positive believes stand, many benefits of physical activity has lost value overtime, as people nowadays have the tendency to rely on modern technologies and machineries, which are believe to make life easier. This often leads to shortage of physical activity and over sometime both physical and mental health will deteriorate. This argumentative essay, will explain how engaging in physical exercises improve one’s mental health.
Thirty minutes of exercise a day may be the trick to keeping bad health away! Cardiovascular exercise strengthens all of the body’s muscles. Well known muscles, such as the ones in the arms and legs are toned and seen as exterior health. Meanwhile, the body’s inner muscles and organs, the heart and lungs in particular, are toughened for optimal inner health. Cardio exercise benefits numerous body systems including, muscular, cardiovascular, and respiratory.
