Best Places To Live In America The cities that top the list as America's best have several qualities in common. Providing and promoting healthy lifestyles is an important aspect of a great city. Healthy cities provide safe and accessible walking and biking trails. To see how your city ranks fill out the questionnaire. People walk for many reasons: for pleasure ... to rid themselves of tensions ... to find solitude ... or to get from one place to another. Nearly everyone who walks regularly does so at least in part because of a conviction that it is good exercise. Often dismissed in the past as being "too easy" to be taken seriously, walking recently has gained new respect as a means of improving physical fitness. Studies show that, when done briskly on a regular. schedule, it can improve the body's ability to consume oxygen during exertion, lower the resting heart rate, reduce blood pressure, and increase the efficiency of the heart and lungs. It also helps burn excess calories. Since obesity and high blood pressure are among the leading risk factors for heart attack and stroke, walking often protection against two of our major killers. Walking burns approximately the same amount of calories per mile as does running, a fact particularly appealing to those who find it difficult to sustain the jarring effects of long distance jogging. Brisk walking one mile in 15 minutes burns just about the same number of calories as jogging an equal distance in 81/2 minutes. In weight-bearing activities like walking, heavier individuals will burn more calories than lighter persons. For example, studies show that a 110-pound person burns about half as many calories as a 216-pound person walking at the same pace for the same distance. Although increasing walking speed does not burn significantly more calories per mile, a more vigorous walking pace will produce more dramatic conditioning effects. When looking at the benefits to heart/lung endurance, how far one improves depends on his/her initial fitness level. Someone starting out in poor shape will benefit from a slow speed of walking whereby someone in better condition would need to walk faster and/or father to improve. Recent studies show that there are also residual benefits to vigorous exercise. For a period of time after a dynamic workout, one's metabolism remains elevated above normal which results in additional calories burned. In some weight-loss and conditioning studies, walking actually has proven to be more effective than running and other more highly-touted activities. That's because it's virtually injury-free and has the lowest dropout rate of any form of exercise. Like other forms of exercise. walking appears to have a substantial psychological payoff. Beginning walkers almost invariably report that they feel better and sleep better, and that their mental outlook improves. Walking also can exert a favorable influence on personal habits. For example, smokers who begin walking often cut down or quit. There are two reasons for this. One, it is difficult to exercise vigorously if you smoke, and two, better physical condition encourages a desire to improve other aspects of one's life. In addition to the qualities it has in common with other activities, walking has several unique advantages. Some of these are:
Almost everyone can do it. You don't have to take lessons to learn how to walk. Probably all you need to do to become a serious walker is step up your pace and distance and walk more often. You can do it almost anywhere. All you have to do to find a place to walk is step outside your door. Almost any sidewalk, street, road, trail, park, field, or shopping mall will do. The variety of settings available is one of the things that makes walking such a practical and pleasurable activity. You can do it almost anytime. You don't have to find a partner or get a team together to walk, so you can set your own schedule. Weather doesn't pose the same problems and uncertainties that it does in many sports. Walking is not a seasonal activity. and you can do it in extreme temperatures that would rule out other activities. It doesn't cost anything. You don't have to pay fees or join a private club to become a walker. The only equipment required is a sturdy, comfortable pair of shoes. Reprinted with Permission of the nhtsa |
