Cooper himself defines aerobic exercise as the ability to use the maximum amount of oxygen during exhaustive work. Cooper describes some of the major health benefits of aerobic exercise, such as gaining more efficient lungs by maximizing breathing capacity, thereby increasing ability to ventilate more air in a shorter period of time. As breathing capacity increases, one is able to extract oxygen more quickly into the blood stream, increasing elimination of carbon dioxide. With aerobic exercise the heart becomes more efficient at functioning, and blood volume, hemoglobin and red blood cells increase, enhancing the ability of the body to transport oxygen from the lungs into the blood and muscles. Metabolism will change and enable consumption of more calories without putting on weight. Aerobic exercise can delay osteoporosis as there is an increase in muscle mass, a loss of fat and an increase in bone density. With these variables increasing, there is a decrease in likelihood of diabetes as muscles use sugars better than fat. One of the major benefits of aerobic exercise is that body weight may decrease slowly; it will only decrease at a rapid pace if there is a calorie restriction, therefore reducing obesity rates.
Also known as a cooling vest or ice vest, the revolutionary vests must be used appropriately for you to experience the best results. You need to use it only when you are at a comfortable temperature. Examples of these scenarios are sitting in your car, watching a football game, driving, working in the office or resting in a room or in an outdoor area when not exercising.
Metabolic syndrome—the evil trifecta of increased blood pressure/cholesterol, high blood sugar, and fat around your waist—is one of the worst side effects of our sedentary lifestyle. It signals diabetes, heart disease, and even early death. But we have an old-fashioned cure to this modern-day disease: exercise. Any cardio exercise, including walking, can stop metabolic syndrome and even reverse the damage, according to a study published in Circulation. But intensity is the key to revving up your metabolism. Rather than just taking a leisurely stroll, try alternating walking fast and slow. Here 16 more ways to channel the benefits of walking into weight-loss.
Typically aerobic fitness is measured as the highest oxygen consumption achieved by a subject on a treadmill or cycle ergometer. Figure 46.8 shows that O2 uptake increases with leg power output to the limit of uptake at VO2max. This power output by the legs represents a direct measure of aerobic exercise performance that can be related to the muscle properties governing the demand and supply of ATP. Our focus is on how these muscle properties determine aerobic leg performance; specifically, how muscles generate and use ATP in power production and how the changes in muscle properties with age affect muscle power production.
Aerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. "Aerobic" means "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism. Generally, light-to-moderate intensity activities that are sufficiently supported by aerobic metabolism can be performed for extended periods of time. What is generally called aerobic exercise might be better termed "solely aerobic", because it is designed to be low-intensity enough so that all carbohydrates are aerobically turned into energy.
Learn how to walk faster. You can boost your walking speed with improvements in your posture, use of arm motion, and using a powerful walking stride. Soon you'll be covering more distance in less time. That will let you burn more calories during a 30-minute workout. Additional tips for burning more calories while walking include using Nordic walking poles or learning the racewalking technique.
OK, so maybe you won’t have the ability to see through walls but you can protect your vision as you age by taking a daily walk, according to a study published in the Journal of Neuroscience. Researchers found that people who did regular aerobic activity had healthier eyeballs and were less likely to suffer from problems like retinal degeneration and age-related vision loss. So even if you aren’t Superman, you’ll still have super sight. Find out what your walking style says about your personality.
Rowers, treadmills, bikes, and cross-country skiers are all effective if you use them. There is some suggestion that some individuals are more inclined to exercise at home with equipment than at the gym or a class. The activity you choose is a personal choice and it varies for everyone, and so you need to experiment until you find what works best for you. Some individuals prefer to go to the gym while others are perfectly content to work out at home on their own equipment in front of their TV. TV can make the time pass quickly, and so can your favorite movie, music, scholarly courses taught by professors, or books on tape (see resources for online vendors). Finding something that will distract you might just make that 30-minute workout bearable, and believe it or not you might even look forward to it! After all, it could be the only 30 minutes in your day that you have all to yourself. Indulge! Aerobic exercise videos and DVDs are also effective if you use them! They are convenient if you prefer to work out at home instead of taking a class at a studio or a gym, and there are hundreds to choose from. I suggest that you check out Collage Video (http://www.CollageVideo.com), or give them a call and ask for a recommendation. Also check if your local library rents exercise videos on tape or DVD. And by the way, there are videos for all types of activity; from weight training, to tai-chi, to stretching. Check out all the possibilities to add flexibility and strength-building to your cardio workout.
1. It counteracts the effects of weight-promoting genes. Harvard researchers looked at 32 obesity-promoting genes in over 12,000 people to determine how much these genes actually contribute to body weight. They then discovered that, among the study participants who walked briskly for about an hour a day, the effects of those genes were cut in half.
Your weight x distance = energy used walking. Time does not matter as much as distance. If you speed up to walking a mile in 13 minutes or less, you will be burning more calories per mile. But for most beginning walkers, it is best to increase the distance before working on speed. A simple rule of thumb is 100 calories per mile for a 180 pound person.
Mental health got me walking in the first instance. I was in my late twenties, and beginning to understand that the love of my life (London) was also my chief tormentor. The stress of the city and the stress of my job as a journalist, got the better of me and I became claustrophobic, which meant I could no longer stand to travel around London’s endless sprawl by Underground. (I’ve since discovered this is incredibly common in Londoners, and God, how transparent we all are! The thing that ferries us to work, aka ground zero on much of our stress; the thing that speeds relentlessly round our city - its logistical arteries - is also the thing we’re likely to fall apart on, and ultimately: resist and refuse.) So I ditched the tube for the bus.
Running and racewalking burn more calories per mile. Running burns more calories per mile than walking, likely due to the effort of the lift phase, which raises both feet off the ground at the same time during running. You can burn more calories by adding running intervals to your walking workouts. With the racewalking technique, you use more muscles during a stride compared with regular walking or running and that results in burning more calories per mile.
However, I also do some form of "exercise" every day. This includes strength training twice a week, HIIT twice a week with weights or on an elliptical machine, and a light 10-minute workout three times a week on recovery days. But since walking isn't exactly exercise, you can do it everyday without needing any recovery days for your body to repair and regenerate; it doesn't tear down your body much, so it doesn't require recovery time.
Start exercising: Many exercise programs say to talk to your doctor before starting. Certain people with specific medical conditions may want to check with their doctor before becoming physically active, however; most people can start a simple walking program without problems. Even those recovering from heart attacks are encouraged to walk treadmills in cardiac rehabilitation programs.
Before beginning any exercise program, especially if you have heart or other health issues, talk to your doctor. If you’re not doing much aerobic exercise at all currently: “Start with a lighter volume of aerobic exercise and gradually work your way toward some specific goals,” advises Tripps. Over time, as you improve your aerobic fitness, you will be able to increase your exercise intensity.
The list of studies that show that aerobic exercise prevents or reduces the occurrence of cardiovascular disease is so long that it would take this entire article and probably five others just like it to review all of the research. One of the most important is one of the earliest. In a study of more than 13,000 men and women, it was shown that the least fit individuals had much higher rates of cardiovascular disease than fit individuals -- in some cases, the risk was twice as high. Aerobic exercise works in many ways to prevent heart disease; two of the most important are by reducing blood pressure and allowing blood vessels to be more compliant (more compliant means that they become less stiff and it's less likely for fat to accumulate and clog up the vessels). Results like these have been proven over and over again.
Here’s what’s happening in your body when you’re running and walking: “Muscle action that propels you from point A to B requires the utilization of a thing called ATP,” explains Janet Hamilton, an exercise physiologist and running coach with RunningStrong. “Your body stores only a limited amount of ATP (enough for only a few seconds of activity), so it needs to replenish that supply, and it does so by metabolizing your stored fuels (glycogen and fat). The process of making useable energy (ATP) from stored fuel (glycogen and fat) is dependent on how much you need and how quickly you need it.” So the more intense the activity, the greater the demand for fuel—and since walking is less intense and demanding than running, it doesn’t demand that ATP be produced at the same rate.
The third thing I noticed, was how walking reaffirmed my love for where I loved. When you wander daily around your locale, you start to look at it properly; when you do that, you notice how devastatingly beautiful it is. How weird, how sweet, how contrary, how chic. I saw hidden architectural loveliness and hilarious graffiti; outrageously stylish tiling on the exterior of ancient pubs, unutterably picturesque, Dickensian cut-throughs and alleyways. I saw more of the sky, more often, than I’d ever seen before.
Pedometers also work well for people who simply don't have time or don't take time to walk consistently as a form of exercise. By tracking the number of steps you take each day simply doing your regular daily activities, you may find that you're getting in plenty of exercise. Some experts recommend 10,000 steps a day. Others say this would be an eventual target.
In the end, vigorous running wins out for calorie burn, but remember that calories aren't everything. Obsessing over exactly how many calories you consume or burn is just as unhealthy as not exercising at all. So choose the activity you love most—whether it be walking or running—and focus less on the calories and more on how much better you feel after doing it.

The good news is that weight-bearing exercise, including walking, can help maintain and even build bone density, reducing the likelihood of osteopenia, osteoporosis, and fractures. The thing to keep in mind is that the bone-saving benefits only occur in the bones and muscles being forced to work against gravity to bear weight. For instance, walking can help maintain bone density of the legs, hips, and spine, but won’t improve bone density in the shoulders or arms. You would need to add other exercises, such as pushups, to your exercise routine to do so.
Select an activity with a high probability that you will stick with it. It doesn't necessarily have to be fun, it just has to be something realistic that you are willing and able to do. You're probably setting yourself up to fail if you work 12 hours a day, take care of three young children, and still plan to use a treadmill at a gym that's a 45-minute commute from where you work or live. Instead, choose something more convenient. I love the "five minutes out, five minutes back" plan to get started. Just like it sounds, you walk out for five minutes at a moderate intensity (aerobic exercise), turn around, and walk back. That's it. Ten minutes of walking and off you go about your day. If you feel ambitious, start with seven and a half or even 10 minutes out and back, and add some abdominal crunches if you like when you finish. Keep in mind that you can always add more later on. The important thing is to get started.
Your heart gets stronger and pumps more blood with each beat (larger stroke volume). Elite athletes, as I just mentioned, can have stroke volumes more than twice as high as average individuals. But it's not just that. Conditioned hearts also have greater diameter and mass (the heart's a muscle too and gets bigger when you train it), and they pump efficiently enough to allow for greater filling time, which is a good thing because it means that more blood fills the chambers of the heart before they pump so that more blood gets pumped with each beat.
Mitochondria inside the muscle increase in number and activity. Mitochondria are the powerhouses of your cells. They do all the heavy-duty work to keep you moving. They use the oxygen to burn the fat and carbohydrate that makes you go. The good news is that they increase in number and activity, by as much as 50%, in just a matter of days to weeks in response to regular aerobic exercise in adults of all ages.
These electrons have powerful antioxidant effects that can protect your body from inflammation and its many well-documented health consequences. For example, one scientific review published in the Journal of Environmental and Public Health concluded that grounding (walking barefoot on the earth) could improve a number of health conditions, including the following:14
The general rule for increasing aerobic activity is 10% per week. Interestingly, there's no evidence to suggest that a 10% increase is the safest and most effective amount of time to increase, but that's the rule of thumb and it seems to work pretty well. So, if you're walking for 20 minutes then the next increase ought to be two minutes for the following week. The bottom line though is to listen to your body. If you find that increasing by 10% is very easy, then go ahead and try a little more. But if you find that you are tired for hours after your workout, or chronically sore or achy from your workouts, then you know you need to cut back to 10% increases. Learn how to listen to your body and everything should be OK.
Your heart beats approximately 60-80 times per minute at rest, 100,000 times a day, more than 30 million times per year, and about 2.5 billion times in a 70-year lifetime! Every beat of your heart sends a volume of blood (called stroke volume -- more about that later), along with oxygen and many other life-sustaining nutrients, circulating through your body. The average healthy adult heart pumps about 5 liters of blood per minute.
Getting a solid eight hours snoozing in the sack is one of the most important things you can do for your health. But sometimes that’s easier said than done. Thankfully a brisk walk is basically Ambien, minus the pill (and the scary sleep-walking stories). In a large meta-analysis of sleep studies, researchers found that regular walkers had longer and better quality sleep. And for those unlucky few who still had insomnia? Walking helped reduce the number of sleepless nights they experienced. Find out which side of the road is safest for walking and why.
Stumped for an idea? Take a quick stroll around the block. Whether you need a solution to a problem at work or you’re looking for inspiration for your novel, walking gets your creative juices flowing in all areas. A recent study published in Frontiers in Neuroscience found that walking improved both convergent and divergent thinking, the two types associated with enhanced creativity.
As you get started toward the recommended 30 minutes of moderately intense aerobic exercise five days per week, aim to exercise at a level that just lets you keep up a conversation during the activity. If you can get out three or four sentences in a row without gasping for air, it’s a sign that you’re maintaining an intensity that is truly aerobic, meaning aerobic metabolism is supplying the vast majority of your body’s energy, Jonesco says.
In normal daily activity, adults cover about 2-3 miles. About 2,000 steps equal a mile. To make walking a beneficial activity, you would need to come up with at least another 4,000 steps in a day. You can find ways to add steps here and there, such as walking farther from parking lots, taking stairs when available instead of escalators and elevators, walking the long way to get somewhere in your office building, walking your children to school, having a walk/talk meeting instead of sitting down in a conference room, or planning a short walk around the block as a break.
Improper digestion can lead to gastrointestinal discomfort, bloating, constipation, diarrhea, and even colon cancer. Therefore, it is very important that you keep your digestive system healthy. Apart from maintaining good food habits and drinking water, you should also walk to improve digestion. Walking after meals is great. It helps you reduce weight and also supports your digestive system (11) (12).
