Whatever your preferred exercise intensity, it’s also important to choose activities that you enjoy and will stick with over the long term. Walking, biking, hiking, dancing, and gardening are all great forms of aerobic exercise that you can easily integrate into your day. After all, aerobic exercise can greatly improve your health even if you perform it in shorter segments throughout the day.
“I like to say that running is a gift. Not everyone gets that gift. If you’re one of the ones who has been gifted with the ability to run and enjoy it, then treasure that gift. Nurture it and never ever take it for granted,” says Hamilton. “But walking is a wonderful activity and for those who don’t have the ability or desire to run, it can provide huge health benefits. The difference in calorie burn between briskly walking a mile and slowly running a mile is minimal—the more noticeable difference is how long it took you to cover the distance. Walking builds and maintains lower extremity and core strength, helps clear your mind, and, for runners, it’s a great way to have an active recovery day.”
Walking is a great exercise and helps you lose weight. American scientists designed an experiment where obese patients walked together (a concept known as the ‘walking bus’) to their destinations in and around the city. After 8 weeks, their weight was checked, and more than 50% of the participants lost an average of 5 pounds (4). Therefore, it might be a good idea to start walking to and from your nearby destinations, instead of driving your car.
Impaired aerobic capacity, also known as impaired endurance, is a common patient impairment that can limit participation in functional, occupational, and recreational activities. Even functional tasks that require only a few minutes can be limited by aerobic capacity. Older adults are particularly vulnerable to impaired aerobic capacity due to anatomic and physiological changes that occur with aging, greater propensity for sedentary behaviors, and greater risk for disease processes that limit the oxygen transport system.1 In addition, aerobic capacity is directly influenced by the habitual activity pattern of an individual, which may vary across individuals from total inactivity to frequent and intense activity. Any factors that limit habitual physical activity, such as illness, injury, and or travel, will cause adaptations that diminish aerobic capacity. Conversely, any factors that promote habitual physical activity, such as intentional exercise, yard work, and occupation-related physical tasks, will result in adaptations that improve aerobic capacity. In older adults, many physiological, pathological, and psychosocial factors can contribute to restricted physical activity. Figure 12-1 depicts the persistent vicious cycle that can be created when sedentary behaviors, chronic disease, and functional dependency interact.2 This chapter will provide an overview of causes and factors contributing to impaired aerobic capacity in older adults and describes physical therapist patient management (examination, evaluation, diagnosis, and interventions) to address decreased endurance and its impact on function.
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).
In light of the benefits associated with HIIT, Dr. Nose created a regimen of fast walking and gentle strolling, to see if this kind of program might provide greater fitness benefits than walking at a steady pace. The program consisted 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. The results turned out to be very promising. As reported by the "New York Times":13
4. Better memory and cognitive function. A clinical trial of older adults in Japan published in the Journal of the American Geriatrics Society in 2015 found that after 12 weeks, men and women in a prescribed daily walking exercise group had significantly greater improvements in memory and executive function (the ability to pay focused attention, to switch among various tasks, and to hold multiple items in working memory) compared with those in a control group who were told just to carry on with their usual daily routine.
Dancing, swimming, water aerobics, biking, walking, hiking, climbing steps (two at a time for a more vigorous workout), low-impact dance classes, kick-boxing, all the cardio machines at the gum (treadmill, elliptical, bike, rower, x-c skiing, stair-climber), and many other activities are all examples of types of aerobic or cardio activities, but they can be anaerobic too if they are performed at a high enough intensity. Try riding your bike alongside Lance Armstrong in the French Alps and you'll know what anaerobic exercise means in moments. But then again, riding along on your bike at a leisurely 8-10 mph on the boardwalk at the seashore is the same activity, but at a much lower intensity, much lower heart rate, and much lower oxygen consumption, and so in this case, biking is aerobic. The bottom line is that the intensity at which you perform an activity determines if it's aerobic or anaerobic.
“This has all been scientifically proven,” says Hall. “Dr Darren James, research fellow at South Bank University, has done a study showing all this. WalkActive significantly and statistically improves your posture, increases your walking speed by up to 24%, reduces joint impact, joint stress at the knee and at the ankle and improves your body shape.” It is, unmistakably, a fitness programme, as in, you would undertake it for the same reasons as an aerobics class, to lose weight, or at the very least, redistribute it in a more sightly way. I did several 10-minute walks, and while never out of breath, was certainly more tired at the end than I would normally have been.
Studies have shown that (1) microbial community composition may play an important role in xenobiotic processing in soil and other soil processes (Cavigelli and Robertson, 2000; Balser et al., 2002) and (2) the microbial communities residing at depth are not simply diluted analogs of the surface microbial communities, but exhibit considerable differentiation (Ghiorse and Wilson, 1988; Fritze et al., 2000; Blume et al., 2002). In fact, the microbial communities in the soil subsurface may function differently from those at different depths. Aerobic microbes predominated the surface soil or soil rich in moisture and oxygen, whereas anaerobic microbes predominated the deep soil (Li et al., 2014a; Fierera et al., 2003; Blume et al., 2002).
“Carrying extra weight will increase the intensity and your calories burned without requiring a lot of extra effort, depending on the weight you use,” adds Spraul. "You can hold dumbbells in your hands or put some heavy books in a backpack — whatever works for you! It doesn't have to be complicated. Just make sure that the added weight is not throwing you off balance.”
One Stanford University study found that walking increased creative output by an average of 60 percent. Researchers labelled this type of creativity “divergent thinking,” which they define as a thought process used to generate creative ideas by exploring many possible solutions. According to the study, “walking opens up the free flow of ideas, and it is a simple and robust solution to the goals of increasing creativity and increasing physical activity.”
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.
Add Weights: Another way to add intensity to a walking routine is to use weights. “Whether you're on the treadmill or you hop off on your ‘rest interval,’ you can add weight to keep your heart rate up and add some strength training into the mix,” says Crockett. “While you're walking on an incline, adding some dumbbell shoulder presses or dumbbell jabs can help you tone your arms and burn even more calories. [Or] hop off the treadmill after your fast interval and try some quick high repetition exercises, such as dumbbell squats, squat to press, weighted jumping jacks or weighted sit ups.”
Complete your workout with a three to five minute cooldown. It will give your muscles a chance to slow down gradually and reduce the risk of dizziness. Individuals who stop aerobic exercise abruptly can experience "pooling" of blood in the legs from standing still right after exertion. Cooling down is important after any aerobic activity, so always make sure to take three to five minutes at the end of your workout to slow down gradually.
Your heart rate increases in direct correlation with the intensity of the exercise. Heart rate levels can vary significantly from one person to another based on fitness level, genetics, environment, and exercise tolerance. If you wish to train based on heart rate, contact your health care provider to determine what the appropriate range is for you. Some medications, most often blood pressure drugs, control heart rate, making it impossible to determine exercise intensity in this way. Ask your physician to determine if you are on any of these medications.
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?
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.
Aerobic exercises are typically moderate-intensity exercises involving larger muscle groups that are performed over extended periods to improve cardiovascular function. Examples of aerobic exercise include walking, cycling, and pool exercises. Regardless of what type of exercise is used in the aerobic exercise program, maintaining an adequate aerobic dose of 40% to 60% of maximal aerobic capacity (maximum heart rate or Vo2max) is necessary (see Table 47.1). Aerobic exercise has been recommended as part of the management of patients with a variety of rheumatologic disorders in a number of published treatment guidelines.2,3,32,33 Aerobic exercise programs have been shown to reduce pain, improve function and quality of life, increase aerobic capacity and endurance, and improve mental health.2,33-35
The thinking has also changed somewhat on whether there’s a threshold minimum workout duration required to reap cardiovascular health benefits from aerobic activity. HHS’s new physical activity guidelines eliminated the long-standing recommendation that exercise had to last at least 10 minutes to count toward your daily total. (4) The new guidelines emphasize that small bouts of activity throughout the day can add up to big health benefits.
"By adding some variables into the mix you can turn a simple walk into a fun, fast interval session, burning a high level of calories, and in turn, crushing your fat cells,” adds Rob McGillivray, Founder of RETROFIT in West Hollywood. “Essentially we burn the most calories by repeatedly raising and lowering the heart rate, as opposed to keeping the heart rate at one steady pace, whether that be high or low. So, if you were to compare the heart rate fluctuations of someone walking up a mixture of steep hills and then add in variations of walking speeds, styles of walking (such as lunging, striding, side cross overs, etc.) to that of someone primarily running at a medium pace on a level gradient, you could see greater all round results on both your body's caloric burn and a greater degree of lower limb muscle groups being targeted. It is also said that hill walking, as opposed to running on a level gradient, can enable you to burn more fat without attacking lean muscle tissue.”
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
Classes are generally rated as beginner, intermediate, and advanced. Choose the level that fits your condition. It's no fun taking an advanced class if you're a beginner. It will be hard and frustrating and you won't enjoy the experience. Watch the class or speak with the instructor to help you decide what's right for you. Sometimes it comes down to the class time that fits your schedule, but just be sure to not get in too far over your head.
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.
