Disadvantages Of Aerobic Exercise

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

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.

According to Mayo Clinic, “exercise benefits every part of your body, it helps you feel better, have more energy, and contributes to your life expectancy.” (Mayo, 2011).

I learned that anaerobic is an organism or tissue that is living in the absence of air or oxygen while aerobic is involves the organism or tissue receiving and requiring air. Furthermore I learned about the anaerobic cellular respiration that uses an electron acceptor rather than oxygen to complete metabolism using electron transport-based chemiosmosis. Also in this reading I learned about fermentation which is an anaerobic process in which energy can be released from glucose even though oxygen is not available.

In this assignment I will be reviewing the different effects of exercise on the body system including the acute and long term using the pre-exercise, exercise and post-exercise physiological data which I collected based on interval and continuous training method. I will also be including the advantages and disadvantages of these, also the participants’ strengths and areas where they can improve on.

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.

Introduction: Exercise is a physical activity or particular movement that is used in order to become healthier and stronger. (1) Exercise, in all of its forms, has various effects on the different systems in the human body. One of the main benefits is cardiovascular health, including circulation and heart health. Exercise uses a lot of energy, which the cells derive from oxidising glucose. Meaning that the heart has to work harder to pump more blood throughout the body and the heart has to beat faster in order to achieve a high effort. (2) The heart benefits from exercise include being able to pump more blood through the body and continue working at a higher level with less strain. (3)

of physical exertion. Regular physical activity has significant health benefits, and even modest increases in energy expenditure can have health enhancing effects.

There are many benefits of cardio fitness, the main advantages are; improved heart health, increased metabolism, improved hormonal/ mental health, and helps manage or ease the chances of diabetes. Your heart is a muscle, and in order for it to gain strength it needs to be worked, by getting the heart pumping at a faster rate than usual it will become stronger, larger and healthier. Cardio exercise uses lots of energy from cells to keep working your muscles. When burning calories you change from a resting level of metabolism (normal) to an exercising rate of metabolism. By doing cardio exercise for 20 minutes each session, you increase the level of your metabolism. Cardio exercise changes the hormonal profile in the body on a large scale. Exercises release hormones within the brain and nervous system, called endorphins. These hormones lessen the symptoms of depression, stress disorders and fatigue. Cardio exercise helps diabetes sufferers manage the condition. By exercising the ability to utilize glucose will increase and will help control blood sugar levels, and lessen the chances of blood sugar swings. It lowers the chances of getting type two diabetes by maintaining blood glucose and blood pressure levels at

Oxygen is required by the cells to carry out respiration, this provides the energy in the form of adenosine-triphosphate (ATP) which is a molecule required for muscular contraction. As exercise takes place, oxygen is used

Exercise, or physical activity helps your body in many ways. For example, exercise helps control the weight of a human. It helps prevent people gaining unwanted weight and helps people who have unwanted weight to lose it. (mayoclinic.com) When we eat, we are taking in calories, and then when we exercise we burn off

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

Measurement of aerobic/anaerobic capacity allows evaluation of individual’s metabolic abilities, indicates state of fitness and effectiveness of training programs.

The benefits of physical exercise in humans far outweighs the harmful effects associated with exercise. A prescription of physical activity has been known to delay the onset or prevention of many chronic diseases. An improvement in heart function, lower blood pressure and improve functional capacity is noticed after just a few weeks of exercising. Physical activity will also result in an increase of lean muscle mass, promote weight maintenance, increased flexibility, and a generally stronger more fit individual. Conversely, exercise when preformed strenuously or obsessively can counteract such positive effects, bringing up some issues like oxidative stresses, injuries, and
