Knowing how many calories you continue to burn after finishing an aerobic workout enables you to optimize your workout results. In addition to gender, physical fitness, and exercise duration, the afterburn effect of aerobics depends mainly on your exercise intensity. The bottom line: the higher your exercise intensity the greater the afterburn.
About the Afterburn Effect
The afterburn effect, which is also known as excess post-exercise oxygen consumption, or EPOC, kicks in immediately after finishing your workout and can last anywhere from 15 minutes to 48 hours. During this period, your body uses up an increased amount of oxygen and energy to return to its pre-exercise, resting state. Your increased body temperature, heart rate and breathing are restored to normal, while lactic acid is removed from your muscles, blood is re-oxygenated and your blood circulation is restored.

Effect of Aerobic Intensity
An aerobic workout with a low intensity will require less recovery than a workout with a high intensity. You continue to burn calories for...

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.
The main question being asked here is how exactly does exercise intensity affect heart rate and blood pressure levels. As exercise intensity relates to heart rate, we believe that as exercise intensity increases, heart rate will go up, but recover slightly during the recovery period. As exercise intensity relates to blood pressure, we would expect both systolic and diastolic numbers to go up as intensity increase, with systolic increasing more due to the body’s need of more blood.
Sport aerobics is a new exiting performance sport, and like any new sport, is seeking recognition and acceptance as a valuable and worthwhile competitive activity. It is said however, that Sport Aerobics will always struggle for popular support because of pre-existing stereotyped views of sport in Australian society. The purpose of this essay is to challenge stereotyped views of sport in Australian society in order to increase participation in Sport Aerobics. To do this a proposed strategy will be implemented at Nambour High School to challenge stereotyped views of sport and breakdown social barriers to the participation in Sport Aerobics. This strategy involves including Sport Aerobics as a compulsory activity in the junior school physical
... uptake during submaximal exercise but did increase heart rate and the rate-pressure product at rest and during both exercise and recovery’.
The extra heat produced during metabolic exchange, raises the body temperature again affecting the enzymes and heat is then removed by sweating. If the body isn’t kept hydrated during exercise, dehydration will occur, causing the blood to become concentrated. When the blood becomes concentrated, the cells no longer have enough water to function.
•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.
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-
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).
When a person exercises the body uses either sugar or fatty acids as fuel to create energy. During the beginning of an exercise most of the sugar that is used as fuel comes from the bloodstream or the muscles. After about 15 minutes the fuel starts to come from the liver. When one exercises after 30 minutes the body receives energy from free fatty acids and glycogen gets stored resulting in a decrease in blood sugar levels. Glycogen is the sugar stored in the liver and muscles.
One of the most important changes would be an alteration in the concentration of hydrogen ions in the blood, this could be caused by a rise in blood carbon dioxide or an increase in tissue respiration in the muscles during the exercise. The respiratory centre is in its self. sensitive to raised hCo2 and responds by increasing the rate and depth. of the breath of the mind. In the aortic arch and carotid bodies there are chemoreceptors.
A regular exercise regimen will not only burn more calories, “but it also releases endorphins, which lower cortisol levels and improve your feelings of well-being. In addition, exercise increases testosterone by adding muscle mass, taking your libido to new heights and improving your body image” says Dr. Laura Berman. This is why effects on activities are something to look for and go
Cardio is a term coming from the word cardiovascular, which is the system of the heart, veins, and blood vessels running through a persons body. So when you do an aerobic exercise, you are doing an exercise that is strengthening your cardiovascular system. Aerobic exercises are generally low intensity workouts, much lower than strength training for example, but go on for much longer durations of time. An example of aerobic exercises would be, but not limited to; swimming, running, jumping rope, biking, rollerblading, and walking. There are a great number of benefits that having a strong cardiovascular system can bring, some of which are, being at less of a risk for heart disease, you will have less stress in your life, and it can ease depression. But one of the biggest reasons for doing aerobic exercise is the fat loss it can bring. Aerobic exercises go on for generally long amounts of time, and in that time you are bound to burn a few calories. When you burn more calories than you take in your body will look to its reserves, its reserves being fat. Your body will use that fat as a source of energy, and this is how fat loss happens. Cardio often goes hand in hand with weight training, because without cardio you will not be able to show off what you have gained throughout your weight
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 those calories taken in before. This helps us control the amount of calories by burning them off, otherwise our body would have stored them away as fat. (fitday.com)
