Aerobic exercise has many benefits. It can help reduce stress, prevent certain types of heart diseases and overall, enhance your health all together. Also, aerobic exercising releases endorphins, meaning that these "natural pain killers" can actually reduce pain in certain areas of your body. It all depends however, if you have a painful leg and go out running, no promises on the endorphin part of the tale. Whichever the benefits might be, I suggest you exercise carefully or even under the supervision of a medical doctor. After all, too much of anything is never good.

Aerobic respiration requires, of course, oxygen to proceed. After glucose breaks down into two molecules of pyruvate (glycolysis), the pyruvate enters the mitochondria to take part in the citric acid cycle (aka. krebs cycle). The krebs cycle makes energy in the form of ATP, NADH, and FADH2. NADH and FADH2 are high energy electron carriers that make more ATP in the electron transport chain, which happens in the inner mitochondrial membrane and uses oxygen as a final electron acceptor. Thus, you can get about a 36-38 ATP yield from aerobic respiration. Comparatively, anaerobic respiration happens without oxygen and only produces 2 ATP molecules per glucose. This happens through fermentation, which produces lactate/lactic acid in humans (so it's not that great, since it causes sore muscles, etc.). Aerobic respiration produces much more energy than anaerobic repiration does, even though glucose is the starting point for both.

Alternate aerobics and strength training.  Aerobics will get your heart rate going (walking, swimming, aerobic tapes) strength training will create muscle which will create energy that burns calories to lose fat.

Hormonal activity is usually a negative feed back mechanism. You would think exercise would feed forward, though, as the rate would keep increasing. Not my area, though, so a functional biologist is needed here.

Yes, \n\nswimming is one of the greatest aerobic activities ever. \n\nAs you might know, fat is burned when you're involved in aerobic excercise.. normally they say after 10 mins of aerobic exercise you start burning fat. with swimming.. you burn it faster

Oxygen to carbon dioxide (breathing), food to energy, sleep to rejuvenation, or maybe that last one wasn't so good, try brain activity (thoughts) to actions (automatic brain commands that keep your heart and lungs functioning)

For cardio, biking. As a cheap and sometimes interesting way to get exercise, walking. Get a good pair of shoes for either. They are both healthy and each has advantages and disadvantages. Walking the same route all the time can be a bore, you have to change it up from time to time.

As our bodies perform strenuous exercise, we begin to breathe faster as we attempt to shuttle more oxygen to our working muscles. The body prefers to generate most of its energy using aerobic methods, meaning with oxygen. Some circumstances, however, --such as evading the historical saber tooth tiger or lifting heavy weights--require energy production faster than our bodies can adequately deliver oxygen. In those cases, the working muscles generate energy anaerobically. This energy comes from glucose through a process called glycolysis, in which glucose is broken down or metabolized into a substance called pyruvate through a series of steps. When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy. But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown--and thus energy production--to continue. The working muscle cells can continue this type of anaerobic energy production at high rates for one to three minutes, during which time lactate can accumulate to high levels.\n\nA side effect of high lactate levels is an increase in the acidity of the muscle cells, along with disruptions of other metabolites. The same metabolic pathways that permit the breakdown of glucose to energy perform poorly in this acidic environment. On the surface, it seems counterproductive that a working muscle would produce something that would slow its capacity for more work. In reality, this is a natural defense mechanism for the body; it prevents permanent damage during extreme exertion by slowing the key systems needed to maintain muscle contraction. Once the body slows down, oxygen becomes available and lactate reverts back to pyruvate, allowing continued aerobic metabolism and energy for the body’s recovery from the strenuous event.\n\nContrary to popular opinion, lactate or, as it is often called, lactic acid buildup is not responsible for the muscle soreness felt in the days following strenuous exercise. Rather, the production of lactate and other metabolites during extreme exertion results in the burning sensation often felt in active muscles, though which exact metabolites are involved remains unclear. This often painful sensation also gets us to stop overworking the body, thus forcing a recovery period in which the body clears the lactate and other metabolites.\n\nResearchers who have examined lactate levels right after exercise found little correlation with the level of muscle soreness felt a few days later. This delayed-onset muscle soreness, or DOMS as it is called by exercise physiologists, is characterized by sometimes severe muscle tenderness as well as loss of strength and range of motion, usually reaching a peak 24 to 72 hours after the extreme exercise event.\n\nThough the precise cause of DOMS is still unknown, most research points to actual muscle cell damage and an elevated release of various metabolites into the tissue surrounding the muscle cells. These responses to extreme exercise result in an inflammatory-repair response, leading to swelling and soreness that peaks a day or two after the event and resolves a few days later, depending on the severity of the damage. In fact, the type of muscle contraction appears to be a key factor in the development of DOMS. When a muscle lengthens against a load--imagine your flexed arms attempting to catch a thousand pound weight--the muscle contraction is said to be eccentric. In other words, the muscle is actively contracting, attempting to shorten its length, but it is failing. These eccentric contractions have been shown to result in more muscle cell damage than is seen with typical concentric contractions, in which a muscle successfully shortens during contraction against a load. Thus, exercises that involve many eccentric contractions, such as downhill running, will result in the most severe DOMS, even without any noticeable burning sensations in the

Sounds like you're on the right track...Aerobic exercise should be done so that the heart reaches it's training heart rate and stays there at least 20 minutes....so usually at least 30 minutes of exercise. \n\nDo not get discouraged....healthy weight gain is 2-3 pounds a week.  anything more can be unhealthy.\n\ngood luck.

*edit*\nSorry, I guess I just don't understand the question. I think the 2nd answer is pretty good. Could you add some more details and I could try to give you a good answer! :) I just thought you meant like what exercise would do for how we look and our health..but I guess not! :) Anyways, if you add some more info I can try to give me more info!

Both actually work, and suprisingly, anerobic (done without using oxygen, so we're talking weights, sprints, push-ups and the like) might be better. As you probably know, you're ALWAYS burning fat, this is called your resting metabolism. Think of it as a pilot light that's always burning. Anerobic exercise causes that light to get bigger, and thus you lose more thoughout the day.\n\nAerobic also burns fat too, of course, and is more effective while you're actually exercising. Plus, it's obviously beneficial for your all around health to improve your respitory and cardiovascular systems.

Aerobic exercise is cardio, such as jogging and cycling. It gets your heart rate up. Anaerobic is weight training, such as lifting weights and leg presses. With weight training, you do a set amount of reps which become difficult near the end. With aerobic, you keep at a steady pace.

Aerobic exercise does not include asking people to answer your homework questions for you on Yahoo!Answers.\n\nYou really should find out and try some, it's quite enjoyable.\n\nEMBRACE YOUR INNER SMURF!!

Yes, because as a result of exercise you exhale more, and when you exhale carbon dioxide is emitted.

Elliptical trainers are the best form of aerobic exercise. It burns more calories in the time allotted. It is low-impact - meaning it is easy on your joints and if you use arm movement elliptical trainers you work the upper body at the same time. Stair climbing is a great form of aerobic exercise but only recommended for fit people. Walking is the cheapest and easiest form of aerobic exercise. \n\nYou should exercise 20-30 minutes at 65-80% Heart Rate capacity. That would be calculated by subtracting your age from 220 then multiplying that number by .65 and .85\nFor example a 25 year old calculation would look like this: 220-25=195bpm 195 x.65= 126bpm 195 x.85 = 165bpm. Therefore, the 25 year old should keep their heart rate in between 126-165 beats per minute.  Keep your heart rate in between these two numbers and you are effectively burning calories.\n\nGood luck!
