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.
Believe it or not, walking can actually increase your intelligence. Walking helps to supply the brain with the required amounts of oxygen and glucose, which helps it function better. It also decreases the levels of LDL cholesterol, which clogs arteries, and hence reduces the risk of stroke (7). So, walking can help improve blood circulation, which helps the brain and cellular functions.
A 2014 study published in the Journal of the American Medical Association showed how walking from an early age can help you stay mobile and independent during old age. The sample size included people between the ages of 70 and 89. After 2.5 years, researchers found that the group of adults which exercised regularly were 28% less likely to become disabled and also 18% less likely to have any episode of physical disability.
The question of BP lowering with aerobic exercise in type 2 diabetics has been studied. In the Early Activity in Type 2 Diabetes (ACTID) trial, 593 newly diagnosed diabetics were randomized to use of a pedometer in a program that included intense counseling or standard or intense dietary advice.46 There was no difference in SBP or DBP after 6 or 12 months, even though the participants using pedometers increased their steps by 17% on average. Whether the exercise was merely of too low a “dose” to be effective is unclear. There may be some male-female differences in BP response to aerobic exercise, with women exhibiting BP lowering with resistance compared with aerobic exercise and men responding similarly to both types of exercise.47 The 2013 AHA Scientific Statement recommends at least 30 minutes of moderate intensity aerobic exercise per day most days of the week.2 The authors assigned dynamic aerobic exercise a Class I, level of evidence A recommendation in those for whom it is not contraindicated. Our review of the evidence since 2013, as well as that from another group, confirm these recommendations.41,48 Whether or not high versus moderate (or interval) intensity training is optimal for BP-lowering as well as other aspects of the dose-response effect (i.e., ideal duration of cumulative exercise per week) and the potential impact of different types of aerobic activity requires further investigation.
One of the most effective ways to gauge how hard you are working during exercise is to monitor your heart rate. Your heart rate is measured in beats per minute (bpm), and you can check it by taking your pulse periodically during your workout. Check either your radial pulse at your wrist or your carotid pulse at the side of your neck. Start with zero to count the pulse beats for 10 seconds and multiply that number by six to determine your heart rate. An efficient alternative to checking your pulse is to use a heart rate monitor, which displays your heart rate throughout your workout.
Whatever makes you feel comfortable is the easy answer. There is no need for fancy spandex or workout clothes, unless that’s what you like. As you start moving farther and faster, you may want to get dedicated fitness walking clothes that wick away sweat or allow you to layer for different weather conditions, but for a beginning fitness walker, comfort trumps everything else.
I walked along my bus route, assuming that sooner or later, my arrival at another bus stop would coincide with the arrival of my bus. But it didn’t. So I walked some more, eventually making it to work, a mere 20 minutes later than I normally would have, calmer than I might have anticipated, and feeling like I’d accomplished something vaguely mammoth before 10am. I also felt liberated. Who wants to be enslaved to their public transport systems, beholden to the schedules, the whims and capriciousness. Suddenly, I had another option.
Triglycerides are a common form of fat that we digest. Triglycerides are the main ingredient in animal fats and vegetable oils. Elevated levels of triglycerides are a risk factor for heart disease, heart attack, stroke, fatty liver disease, and pancreatitis. Elevated levels of triglycerides are also associated with diseases like diabetes, kidney disease, and medications (for example, diuretics, birth control pills, and beta blockers). Dietary changes, and medication if necessary can help lower triglyceride blood levels.
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.
“With that being said, walking is a really good form of exercise and can help you reach your fitness and weight-loss goals. As a lifelong track athlete, who has marveled at race walkers (check out the Olympic walkers on YouTube!), I don’t scoff at walking,” says Ford. “In fact, walking is the suggested workout over running for many people. For example, those with knee, ankle and back problems and also for people who are overweight to obese. Walking is a lower impact exercise and can be done for longer periods of time.”
Whether you’re rowing on water or indoors, it’s important to use the correct technique to avoid injury, especially to the lower back. Other common injuries include knee pain, tendonitis in the wrist and blisters on your hands. If you join a club, you should get advice on technique from the coach; if you use a rowing machine at the gym, ask a qualified instructor. If you row outdoors, you also need to be able to swim and wear a life jacket, know how to row safely — and remember to use sunscreen!
This walking calorie burn calculator estimates the calories that you burn while walking any given distance. The calculator takes into consideration the grade of the walking surface that you are on (i.e. the incline or decline), your weight, and the total walking distance and walking time. The incline or decline of the walking surface is taken into consideration because more calories are burned as the incline of the walking surface increases, and less calories are burned as the decline of the walking surface increases. You can read more about the method and equations used to determine calorie burn below the calculator.
To estimate the amount of energy—remember, energy equals calories—the body uses during physical activity (versus when you’re at rest), scientists use a unit that measures the metabolic equivalent for task (MET). One MET is what your body burns while lounging on the couch watching Netflix. Walking, a "moderate" exercise, uses 3 to 6 METs; running, which is typically classified as "vigorous," uses 6 METs or more.
4: Now to find your true open ankle position. Slowly peel through the back foot until you come to the pivot point between the pad of your foot and your toes. Take a moment to check this position as it will change as your feet become more mobile, strong and fit. Once you have this pivot position hold it there. It’s this position you are trying to achieve with each step as you walk.
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.
5. It boosts immune function. Walking can help protect you during cold and flu season. A study of over 1,000 men and women found that those who walked at least 20 minutes a day, at least 5 days a week, had 43% fewer sick days than those who exercised once a week or less. And if they did get sick, it was for a shorter duration, and their symptoms were milder.
How much good does it do you to get up and walk for a few minutes? Don't be discouraged from walking if you think the number of calories burned is too small. The benefits go beyond burning calories. Simply reducing your sitting time will help keep your muscles, joints, blood circulation, and bones in good working order. By walking more and sitting less throughout the day, you'll burn more calories, reduce your health risks, and do your body good.
Breathing increases during aerobic exercise to bring oxygen into your body. Once inside your body the oxygen is (1) processed by the lungs, (2) transferred to the bloodstream where it is carried by red blood cells to the heart, and then (3) pumped by the heart to the exercising muscles via the circulatory system, where it is used by the muscle to produce energy.
Greater stroke volume means the heart doesn't have to pump as fast to meet the demands of exercise. Fewer beats and more stroke volume mean greater efficiency. Think about a pump emptying water out of a flooded basement. The pump works better and lasts longer if it can pump larger volumes of water with each cycle than if it has to pump faster and strain to get rid of the water. High stroke volume is why athletes' hearts don't pump as fast during exercise and why they have such low resting heart rates; sometimes as low as 40 beats per minute, whereas the average is 60-80 beats per minutes.
