You should walk with great attention to your back foot, as though you’re peeling it off the ground like very strong Velcro. You should pay intense heed to the difference between each of your toes, as they touch and leave the ground. You should be aware of your foot’s contours, and this will activate your large posterior muscle chains, the hamstring and the glutes. Along with your active foot will come an open ankle; if you peel your foot off the ground in segments – so it’s not even thinking about becoming airborne until you come to the pivot point between the pad of your foot and your toes – your ankle will open up and become agile, intelligent.
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.
Heavier people burn calories at a quicker rate than lighter people during every form of exercise, including walking. According to the University of Maryland Medical System, a 120-pound person who walks for 60 minutes at a moderate pace of 2 mph burns about 256 calories. People who weigh 180 and 240 pounds, however, burn about 384 and 512 calories, respectively, during the same length of walk at the same speed.
Want to live longer? Walk. Research has shown that you can add up to seven years to your life by exercising daily, regardless of what you weigh. Even better, those extra years will be good ones as folks who walk are happier. A separate study found that people who exercise report feeling happier, more excited, and more enthusiastic about their future than their couch-potato brothers. Find out how often you should get up and walk if you want to live longer.
Not so much. In fact, running more than doubles the amount of energy you expend versus walking, according to research published in the journal Medicine and Science in Sports and Exercise. A 140-pound person burns 13.2 calories per minute running, according to the American Council of Exercise. That same person would burn 7.6 calories per minute walking. I’ll do the math for you: For a 30-minute run, that works out to 396 calories burned running compared to 228 calories burned while walking for 30 minutes.
Barough has devised different training programmes for beginner, intermediate and advanced levels, for weight loss, and for those with distance goals. I am in training for the Moonwalk marathon this summer (2005), but I started using this book when I was a complete novice and it has held my hand all the way through. I am still referring to it to remind myself of things I have forgotten, for information that is relevant to me now but wasn't when I started, or for the extras I can focus on now that more of my routine has become automatic.
Aerobic capacity is a measure of the ability to perform oxidative metabolism. Multiple systems are involved, including the pulmonary, cardiac, vascular, and musculoskeletal systems. Patients with MD have lower aerobic capacity, especially those patients with aggressive forms of MD (Sockolov et al., 1977; Edwards, 1980; Haller and Lewis, 1984; Lewis, 1984; Wright et al., 1996). Poor aerobic capacity results in reduced activity levels. Other organ dysfunction, such as decline in pulmonary status and cardiomyopathy, may further contribute to declining levels of aerobic capacity.
Cancer has claimed over a million lives. A sedentary lifestyle is one of the causes of cancer, and this is where walking every day can help you. Scientists have found that walking can help in weight loss, thereby reducing the risk of cancer. Walking has been found to be helpful for those undergoing cancer treatment by reducing the side effects of chemotherapy (6). It can also lower the risk of breast cancer.
You got this. You started walking before you could speak in full sentences. Build your walking time and speed incrementally. Start with a 10- to 15-minute walk. Once that feels good, build up your time a few minutes for each outing. Slow and steady wins the race. Remember, at any speed, you're lapping everyone who is just sitting and thinking they should be exercising. Yes, walking is a real exercise.
There you have it. Aerobic exercise is awesome stuff! It strengthens your heart, adds strength to your muscles and makes them more efficient fuel-burners, increases your endurance and your energy, improves your mood, makes you fit and healthy, and much, much more. It could take as little as 30 minutes out of your day for a tremendous payoff so I suggest giving it a shot. Follow my advice for getting started by doing only what is realistic and build up slowly. You have only health and fitness to gain, and you're worth it! Good luck!
What is aerobic exercise?‘Aerobic’ exercise refers to exercise that requires the consumption of substantially more oxygen than at rest. It involves repeated rhythmic movements of the large muscles of your body, such as those in your arms or legs.Examples of aerobic exercise includebrisk walking;jogging;swimming;cycling;dancing;cross-country skiing;ice-skating;kayaking;roller-blading; andaerobic dance (often simply called aerobics).Because you need more oxygen to do aerobic exercise, you breathe more rapidly and deeply to get extra oxygen into your lungs. Your heart also beats faster to deliver more oxygen-carrying blood from your lungs to your muscles.How fast your heart beats and how rapidly you breathe will depend on how intense (hard) the exercise is, with gentle exercise causing only slight increases in breathing and heart rate, but more vigorous exercise resulting in greater increases.Aerobic versus anaerobic exerciseThe term ‘aerobic exercise’ comes from the fact that the energy used during this form of exercise is linked to the consumption of oxygen (aerobic metabolism). Aerobic exercise is of a light to moderate intensity, and is characterised by our ability to maintain it for a prolonged duration (many minutes to several hours).Very strenuous exercise, such as running fast or rapidly cycling uphill uses energy at a very fast rate, and will exceed our muscles’ capacity to work aerobically. Exercise at these higher intensities does involve the use of oxygen, but also requires your muscles to undertake some additional metabolism without oxygen (anaerobic metabolism). This anaerobic metabolism results in the production of fatiguing factors that cause you to have to slow down and eventually stop. The length of time before this occurs will depend on how much anaerobic metabolism is involved, with higher exercise intensities that require greater anaerobic metabolism causing fatigue to occur more quickly.How often should I do aerobic exercise?For general health and fitness benefits, such as reducing your risk of heart disease and improving your stamina, it is recommended that you do some form of moderate intensity aerobic exercise on most, and preferably all, days of the week, for a minimum of 30 minutes a day. This 30-minute total can be made up of shorter 10-minute sessions, if this is better suited to your day. These short sessions will still provide health benefits and produce some fitness improvements, although to substantially increase your fitness you probably need to include at least some 30-minute sessions in your week.To maintain your level of aerobic fitness, and the health advantages that go with it, you need to keep up a regular aerobic exercise routine. Giving up your routine or doing less exercise will cause your fitness and associated health benefits to decline.It’s also important to avoid prolonged sedentary behaviour, such as sitting continuously for several hours. So, in addition to trying to incorporate exercise into your day, you should also try to break up your sedentary behaviours, for example by getting up and walking around your office for a few minutes every hour, or during the advertisement breaks when watching TV.How hard should I do aerobic exercise?To improve your general health and fitness, moderate intensity aerobic exercise is recommended. However, if you are very unfit and currently do no exercise, even short bouts of light exercise will be of benefit. With continued participation, this light exercise will produce fitness improvements that will enable you to progress to moderate intensity exercise.As a general guide, ‘moderate intensity’ aerobic exercise may make you slightly breathless, but still able to hold a conversation, and you should be able to sustain this level of exercise for at least 30 minutes. An example would be when going on a brisk walk, jog or bike ride with a friend.If you want to be more exact in determining your exercise intensity, then you can use your heart rate as a guide. Moderate intensity exercise is likely to increase your heart rate to between 55 and 70 per cent of your maximum heart rate. More vigorous exercise will increase your heart rate even further.How to estimate your maximum heart rateHow to estimate your maximum heart rateYour maximum heart rate in beats per minute = approx 220 minus your ageBut this is a rough estimate, and there is a lot of individual variation. (Your maximum heart rate tends to decline by about 1 beat per year with increasing age.)You can estimate your maximum heart rate by subtracting your age in years from 220. For someone who is 40, for example, their maximum heart rate would be estimated to be around 220 minus 40, which is 180 beats per minute. So, during moderate intensity exercise, this person could expect to have a heart rate between 99 and 126 beats per minute (55 to 70 per cent of their maximum heart rate). However, this is just a rough estimate, and some people can have maximum heart rates more than 20 beats above or below that estimated for their age. So it’s a good idea to also use your perception of how hard the exercise is — the guide of being slightly breathless but able to hold a conversation is a good one.Beta-blockers and exerciseBeta-blockers are one type of medicine used to lower blood pressure as well as treat angina and certain heart rhythm disorders. They work by slowing down the rate at which the heart beats. People taking beta blockers should talk to their doctor about their planned exercise programme. Moderate intensity exercise is often recommended for people taking beta-blockers, but since the heart rate calculations described above do not apply to them, the best guide to determining a suitable exercise intensity is their perceived exertion.Measuring your heart rateIf you do not possess a heart rate monitor, an easy way to measure your heart rate is to count your pulse for 10 seconds then multiply this count by 6 to calculate your heart rate per minute. To find your pulse, locate either your carotid artery (found on the side of your neck, just under your jaw bone) or your radial artery (in your wrist at the base of your thumb). Then gently place your index and middle fingers over the artery, but don’t press too hard or you will stop the flow of blood in that artery and not be able to detect a pulse.Be aware that aiming for a target heart rate when exercising is a rough guide and may not work for some people. Older people who are physically fit may have a higher maximum heart rate than a younger, less fit person, and a higher maximum heart rate than that given by subtracting their age from 220.Progressing to greater levels of fitnessIf you are already active and getting 150 minutes of moderate intensity exercise a week but want to attain a higher level of health and fitness, you will need to increase your aerobic exercise levels, either by exercising at a higher intensity and/or by doing more exercise.Vigorous aerobic exercise — exercising at 70 to 85 per cent of your maximum heart rate — will result in further fitness and health gains. As a guide, at this intensity you will be breathing hard and finding it difficult to talk in full sentences between breaths. This level of exercise is more strenuous and should only be contemplated if you are already accustomed to regular moderate intensity aerobic exercise. To prevent ‘overdoing it’, it is a good idea to alternate between moderate and vigorous exercise days with, for example, 30 or more minutes of vigorous aerobic exercise on 3 or 4 days a week, interspersed with days of 30-60 minutes of moderate intensity aerobic exercise.For people undertaking high-level sports training, a qualified trainer is likely to develop an individualised programme that varies from the above guidelines with regard to the intensity (how hard), the duration (how long) and the frequency (how often) of the aerobic exercise sessions. This is because the main aim of their training is to improve their sporting performance - the associated health benefits that accompany this are a fortunate side benefit, rather than the main goal.A balanced fitness programmeFor people of all fitness levels, aerobic exercise should form part of a balanced exercise programme that also includes 2 to 3 sessions per week of exercise to increase muscle strength, e.g. resistance training; and some stretching and flexibility work, e.g. a basic stretching routine or attending a yoga class. Needless to say, healthy eating and plenty of rest will complete a well-rounded fitness programme.Aerobic exercise precautionsAppropriate aerobic exercise is recommended for almost everybody, regardless of age, but may need to be modified to ensure its suitability for people with existing health problems.If you have existing health problems, are at high risk of cardiovascular disease, or have muscle, bone or joint injuries, check with your doctor before undertaking an aerobic exercise programme. Also, men aged over 40 years and women aged over 50 years who have not exercised regularly in the recent past should check with a doctor before undertaking a programme of vigorous physical activity. The level and type of exercise may be adjusted to ensure that it can be undertaken safely and effectively.As with any form of exercise, be aware of over-exercising, either by doing aerobic exercise too hard, for too long or too often. This approach can lead to injury and abandonment of your fitness programme. Remember to build up gradually from your current activity level, and not to progress too rapidly. If you are new to regular aerobic exercise, several weeks of low to moderate intensity aerobic exercise are usually advised before introducing more vigorous aerobic exercise sessions. When you do increase your level of aerobic exercise, increase only one component — the intensity, duration, or frequency of your aerobic exercise sessions — at a time.It’s never too late to startAn important health and fitness message is that people of all ages can benefit from regular aerobic exercise. And, if you are unfit, unhealthy or an older adult, you may have the most to gain from including it in your lifestyle. Last Reviewed: 24 March 2015
Which one you choose is a personal choice. They are not intended to compete with each other but rather to provide options and maybe even complement each other. For instance, the Surgeon General's recommendation may be more practical for individuals who are unwilling, or unable, to adopt the more formal ACSM recommendation. Of course, there's no downside to working out regularly with aerobic exercise and also becoming more physically active as per the Surgeon General (take more stairs, mow the lawn by hand, park far away from the store and walk), so combining them might be a good decision.
No matter how fast you walk, though, make sure you’re moving at a pace that will challenge your heart and improve your health. You should be able to hold a conversation, but not be moving so leisurely that you could sing a song. If you feel your body begin to get warm and sense that your heart rate is slightly elevated those are other signs you’re moving at an appropriate pace. (Looking for a challenge? This simple, surprising move will make your walking routine way more effective.)
Another American study found that people who walked for at least four hours a week gained less weight (an average nine pounds less) than couch potatoes as they got older. Last year, researchers at the University of Colorado found that regular walking helped to prevent peripheral artery disease (which impairs blood flow in the legs and causes leg pain in one-fifth of elderly people).
A sedentary lifestyle has led to an exponential growth of one of the most common diseases – diabetes. Scientists recommend no less than 5,000 steps a day with more than 3,000 of those steps being a brisk walk – to help manage type 2 diabetes (8). Walking every day can help control the blood sugar levels, which, in turn, can help you prevent type 2 diabetes.
The canon of walking literature has centred, almost entirely, on the infinite charms of an activity that nobody has ever tried to be good at. But the human body has charms of its own, and when its movements go from wrong to right, you recognise it like a melody. Maybe it’s possible to be dynamic and contemplative. Either way, there’s no looking back.
You can get more specific with your aerobic interval training and use heart rate since it's an excellent indication of how hard you are working. Let's use jogging on a treadmill as the aerobic activity in this example. For example, if your heart rate is at 70% of your predicted maximum when you jog at 6 mph, then start at that speed and either increase the speed or elevation so that your heart rate increases to 85% or even 90% for one minute, then back to your usual jogging speed for three minutes to elicit a heart rate of 70%. Start with a 1:3 work:active-rest ratio. That's a good starting point, and as you increase the work intervals and decrease the active-rest ratios like in the examples above, you'll notice that your conditioning improves so that your heart rate will be lower at the higher speeds.
There’s no word yet on if and when this new calculation will be implemented on a wider scale (or be included in your next Fitbit software update). But for now, keep adding extra steps to your everyday routine by parking your car at the end of the lot, or asking your friend or significant other if you can swap those post-work drinks for a scenic stroll instead (or just do both!).
"Oxygen consumption" describes the process of muscles extracting, or consuming, oxygen from the blood. Conditioned individuals have higher levels of oxygen consumption than deconditioned individuals ("couch potatoes") due to biological changes in the muscles from chronic exercise training. For example, a deconditioned individual might have a maximal oxygen consumption of 35 milliliters (ml) of oxygen per kilogram of body weight per minute (ml/kg/min), whereas an elite athlete may have a maximal oxygen consumption up to 92 ml/kg/min! Values like this are expressed as VO2 (volume of oxygen consumed) and can be measured with special equipment in a laboratory.
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 research, presented at the European Society of Cardiology (ESC) Congress, followed 69 people between the ages of 30 and 60. Those who engaged in daily moderate exercise, such as a brisk walk or jog, high-intensity interval training (HIIT), and strength training experienced anti-aging benefits that could add an additional three to seven years to your life.1
One program created by Dr. Hiroshi Nose and colleagues at the Shinshu University Graduate School of Medicine in Matsumoto, Japan consists of repeated intervals of three minutes of fast walking, aiming for an exertion level of about six or seven on a scale of one to 10, followed by three minutes of slow strolling. As reported by The New York Times:13
Observe basic safety while walking outside. Watch for traffic all around you. Always walk on sidewalks or on the left side of the street facing traffic if there is no sidewalk. Carry an ID and a cell phone or change for a pay phone. Use caution if wearing headphones (perhaps use just one earpiece so you can hear traffic and other noises around you). Make yourself visible in low-light situations by wearing reflective gear, such as vests with reflective tape are especially visible.
It all starts with breathing. The average healthy adult inhales and exhales about 7 to 8 liters of air per minute. Once you fill your lungs, the oxygen in the air (air contains approximately 20% oxygen) is filtered through small branches of tubes (called bronchioles) until it reaches the alveoli. The alveoli are microscopic sacs where oxygen diffuses (enters) into the blood. From there, it's a beeline direct to the heart.
Walking also fixes: hangovers, heartbreak, low grade colds; boredom, loneliness, that nagging sensation that you haven’t really achieved anything much today. It has a smattering of downsides. You will get rained on (but not as often as you think, and that’s nothing a sturdy brolly can’t help with). You’ll need to carry posh shoes in a separate bag, and cyclists can be a nightmare, far more troublesome, in my experience, than cars: wayward, melodramatic and happy to mount pavements/ speed the wrong way down one-way streets.
A higher percentage of fat is burned during aerobic exercise than during anaerobic exercise. Here's why. Fat is denser than carbohydrate (fat has nine calories per gram and carbohydrate has four), and so it takes more oxygen to burn it. During aerobic exercise, more oxygen is delivered to the muscles than during anaerobic exercise, and so it follows that a higher percentage of fat is burned during aerobic exercise when more oxygen is available. When less oxygen is present, like during anaerobic exercise, a higher percentage of carbohydrate is burned.
Try to make walking a routine – for example, try to walk at the same time each day. Remember, you use the same amount of energy, no matter what time of day you walk, so do what is most convenient for you. You may find that asking someone to walk with you will help make it a regular activity. Some people find that keeping an activity diary or log also makes it easier.
The American Heart Association recommends that everyone reach a minimum of 30 minutes of some form of cardiovascular exercise 5 to 7 days per week. This can be broken up into 10-minute time periods. This means that taking 3 walks of 10 minutes each would let you reach the recommended minimum guideline for reducing the risk of heart disease, diabetes, hypertension, and high cholesterol. You would also burn the same number of calories as you would if you walked for the full 30 minutes at 1 time.
There is a very big discrepancy between the Kcal burned for 30 minute elliptical on your calculator, vs the cound on the machine itself. 100% difference. When my elliptical says 300 Kcal, this calculator says 679. I don’t know which is right, but the guy at the YMCA says trust the machine (though I haven’t entered ht, wt, etc). What is your take on this?
Researchers at Southern Methodist University took a close look at the most common equations used over the past 40 years. And surprise! They found two major problems: First, the sample sizes that these equations were based off of were way too small (only six people for one method), and only included men. Second, this data didn’t take into account that people of different sizes expend energy at different rates (for instance, heavier people burn fewer cals per pound when walking the same distance as those who weigh less). As a result, when the researchers put these two equations to the test, they found that their calorie estimates were too low in a whopping 97 percent of cases.
