FEELING GOOD RUTHAN BRODSKY Special to The Jewish News W alking is a wonder- ful exercise. It's safe and easy — something we've been doing almost our entire life. It re- quires little or no instruction. It's also an inexpensive and effective way to become fit. The • United States has a limited, tradition of walking; distances from home to work or shops are usually too far. Neighborhoods center around the automobile with few places to walk except in the streets for most suburbs. Yet, this oldest form of locomotion is now attracting 55 million people across the country. Walking is becoming America's most popular fitness activity. Benefits of Walking People walk for a variety of reasons: to improve their physical fitness, to lose weight, to relieve stress, and to improve their mental well being. Findings about the health benefits of lifelong exercise suggest that walking is an almost ideal activity. Walking can improve aerobic activity, help prevent osteoporosis, and provide a bridge to more in- tense exercise. Based on review research from The Centers for Disease Control, Atlanta, they con- clude that physical inactivity is causually associated with coronary heart disease (CHD). In addition, The New England Journal of Medicine reported a study of thousands of Harvard alumni sug- gesting that a long-term regimen of walking (an average of nine miles a week) can significantly prolong life. At Western New Mexico University, two groups of women - one premenopausal and the other postmenopausal — improved their cardiovascular fitness and increased their percen- tage of lean body mass (at the expense of fat cells) through brisk walking _ . According to Steven M. Korotkin, M.D., cardiologist and director of the Cardiatric Rehabilitation Center in Bir- mingham, vigorous walking is excellent for cardiovascular fitness. "Duration as well as distance are important fac- tors for getting the most benefit from walking," said Korotkin. "For example, an average person will probably get the most benefit out of walking briskly for 30 to 45 minutes at least three or four days a week. Walking an hour will get you greater benfit but u, a, Gayle Finn (left) and Marci Shulman socialize on their daily walk in their West Bloomfield neighborhood. Pounding The Pavement Walking is becoming the most popular and ideal fitness activity in America the return per minute is not as good!' Korotkin recommends walking because his patients enjoy walking. Walking helps them maintain their interest in an exercise program. Studies show that 50 percent of adults who start . an exer- cise program will quit within a short period of time. "Walking can be done socially - with a friend or with a group of friends," Korotkin explains, "so patients need less motivation to walk than they would to jog or swim. Moreoever, if they've been rather sedantary most of their adult life, walking is a good starting point for an ex- ercise program!' Jay Kozlowski, M.D., car- diologist at Huron Valley Hospital, recommends that older people and those who haven't been involved in a regular physical activity for some time get their physi- cian's approval before they embark on a' walking program. "How much walking in- dividuals should do depends on their age, weight, level of fitness and desire," says Kozlowski. "To achieve the best results for cardiovascular fitness, individuals can deter- mine how hard to exercise by keeping track of their heart rate?' Exercise above 75 percent of the maximum heart rate may be too strenuous unless you are in excellent physical con- dition reports the American Heart AssOciation (AHA). On the other hand, exercise below 60 percent gives your heart and lungs little condi- tioning. Therefore, according to the AHA, the best activity level is 60 to 75 percent of your maximum rate. This is what's known as your target zone. lb find your target zones, look at Chart A for the age category closest to your age and read the line across. For example, if you are 43, the closest age on the chart is 45; the target zone is 105 to 131 beats per minute. To see if you are within your target zone, take your pulse immediately after you stop exercising. count your pulse for 10 seconds and multiply by six. A second benefit of walking is that it helps keep bones strong. As a weightbearing exercise, walking supports stronger, denser bone develop- ment which may be an impor- tant factor in preventing osteoporosis. Walking also promotes muscle strength when good posture is practiced. The best technique for promoting good muscle strength and reducing back strain is to walk with a straight back, stomach and buttocks pulled in, and to stride forward with arms free- ly swinging. Walking also helps control weight. Brisk walking burns about 450 calories per hour. And finally, walking im- proves flexibility. It stretches muscles and conenctive tissue such as ligaments and ten- dons which help reduce the risk of injury, keep joints sup- ple and ease aches and pains. Before you Begin Most people don't need to see a doctor before they start a walking program because they're in reasonably good health and their walking pro- gram is sensible. However, there are some people who should seek medical advice. For example, if elderly people aren't accustomed to vigorous activity, they may wish to check with a physician to get an indication of their fitness - level. Wendy Schwartz, program director for the First Step Fitness Center in Troy, develops fitness profiles for individuals. In the Personal Fitness Pro- file, patients are given a treadmill stress test and a lung function test. They are also tested for strength and flexibility and body fat is analyzed together with blood cholesterol levels. Patients are then told about their cur- rent level of fitness and how it can be improved. "We use the FITT principal to help our patients: F for fre- quency; I for intensity of ex- ercise, T for type of ideas and T for time," explains Schwartz. "We also help folk figure out what heart rate they should be working out at to get the most from their ex- ercise program." THE DETROIT JEWISH NEWS 3 F -
