ideal body weight using body fat percentage instead of height and weight tables. Vander explained that a person can look thin, yet be coated with fat. She also told me some people are overweight but have little body fat. These most likely are the body builders. I sure- ly wouldn't mind substituting a few fat pounds for muscle weight. She suggested a meeting with a staff dieti- cian. Why not? Next on the list was the ex- ercise test, which measures aerobic capacity, the amount of oxygen the body is able to use. Aerobic capacity is deter- mined by the efficiency of the heart, lungs and blood vessels in their ability to deliver needed oxygen. 'Ib prepare for the exercise test, Vander placed 10 elec trodes on my chest to monitor a 12-lead electrocardiogram monitor. She took my resting heart rate — 50 beats per minute — and my blood pressure — 108/70. Vander then advised me that my heart rate and blood pressure also would be monitored throughout the test. The treadmill gradually would become more difficult. I should stop when I feel fatigued. I might need to jog to keep up with the treadmill. Then, two doctors joined us for the test. Okay, I thought, this will be a piece of cake. I stepped up onto the treadmill and started walking. Seemed easy. I told her so. It got harder. I gritted my teeth and kept going. I survived for about 12 minutes. At the end, my heart rate had jumped to 193 beats per minute and my blood pressure measured 180/70. I didn't understand any of the figures. Vander told me I reached 12 mets, which measures aerobic capacity by taking into account the volume of oxygen used and body weight. The higher a MET level, the more work or exercise can be performed. A level of 12 means I exercised at 12 times my functional work capacity, called resting oxygen consumption. Oxygen consumption is determined by the grade and speed of the treadmill. The EKG clinically interprets the test for evidence of coronary heart disease. I nervously waited a week for my complete results. The bottom line: I was above normal fitness with a heart health score of 96 per- cent. Still, I contained a bit too much fat. With a healthy diet and some weight train- Glenn Triest Fitness maven Ruth Messinger pumps iron at Vic Tanny. Jewish Grandmothers Prove Fitness And Aging Can Mix MIKE ROSENBAUM R Staff Writer uth Messinger spends most of her adult life dealing with family or work- related crises. After all, stress has been a constant companion for the 64-year- old Messinger. Yet Messinger, now a grandmother, found a way early on to help her combat the pressures of daily living: regular exercise. Messinger and other seniors who exercise help dispel the myths that aging is synonymous with illness. She does vigorous exercise, which has contributed great- ly to her excellent health condition. She joins two other Jewish grandmothers — Joyce Weckstein, who teaches rac- quetball, and Sylvia Zukin, former director of the Jewish Community Center's women's health club — in her devotion to health and fitness. In fact, a recently released University of Michigan study reveals that exercise may help seniors live more active lifestyles. The study indicates that exercise may allow frail seniors to become more mobile and flexibile, which increases their ability to live independently. "Exercising even at a low intensity level has a positive impact on the health of chronically ill older people who are at risk of going to nursing homes," says Dr. Tom Hickey, director of the study and professor of health gerontology at U-M School of Public Health. Study participants were 65 to 98, overweight with ar- thritis. Most had never exer- cised. For the study, the men and women exercised for 45 minutes, twice a week, doing basic exercises such as neck and shoulder rolls, twists and stretches for flexibility. After six weeks, participants were more mobile, the study shows. Unlike the study par- ticipants, Messinger, Wecks- tein and Zukin do not suffer from common ailments associated with aging such as obesity and arthritis. And they thank exercise for that. Messinger takes no medica- tion, does three, hour-long workouts every week, swims, dances, runs and plays tennis. With each new stressful situation, Messinger finds an activity to help her dif- fuse tension. After leaving a promising teaching job at Wayne State to move to Florida with her former husband, Messinger took up tennis. "Instead of sticking with the loss in my craw," she says, "what I did was take the anger, take the loss and put it into the ac- tivity that it took to become a good tennis player." When a relationship with a man ended because he could not handle pressures associated with two of her children, who suffer from long-term illnesses, Mess- inger took up running. Messinger's devotion to athletics did not begin in adulthood. A tomboy, Mess- inger grew up playing sports, . and never stopped. She has been. active in basketball, swimming, fencing and dance. Sylvia Zukin still teaches exercise classes at the Maple/Drake JCC and offers students private lessons. She likes to swim and walk and, like Messinger, is in great shape. Zukin advises those wishing to follow her exam- ple to begin early. "When your range of mo- tion becomes smaller, that's indication enough for you to "After the age of 25 or so you start deteriorating. The only way that you can keep your body alert and alive is to use the brain, then put the body into use." know that you have to do something. Because the muscles get tighter and shorter and you can't func- tion." Zukin says young people can function well without thinking about how they move their bodies. However, "after the age of 25 or so you start deteriorating. The only way that you can keep your body alert and alive is to use the brain, then put the body into use." Zukin believes in body awareness, knowing how your body works and moves, and what movements and positions are right for it. Messinger, who works at Vic Tanny, does "everything that I did when I was a kid." That includes her workout, which includes15 minutes of fast walking, 15 minutes of aerobics and 30 minutes on various exercise machines, including arm, leg and chest machines. She uses all of the machines at her club in dif- ferent workouts. She says she can run as fast as most of the 30-year- olds she sees at Vic Tanny. "I could maybe outlast them in a workout on the floor, depending on how grooved they were in exercise." Joyce Weckstein has no name for her fitness philosophy. That is probably because she is too busy to come up with one. A former physical education teacher, she teaches racquetball and speedwalking classes at the Jewish Community Center and Franklin Racquet Club. She also hikes, cross-country skis and volunteers for several charitable projects. As do her friends, Zukin and Messinger, Weckstein benefits from her life-long devotion to fitness. "It means being able to do anything" she says. "I'm always ready to undertake any kind of sports or trekk- ing. I did a hiking trip to Israel two years ago. I was in the Israeli army last year (as a volunteer working in a warehouse) for three weeks. So, by being in ultimate shape, I can always take off immediately. "I just find that it's an ex- cellent way of life. I think you get more energy, you're more creative. I really out-do, in my energy, many younger people." Weckstein says she has been "more active and more productive in my last 10 years" than she was before. For those who have not always lived a fit life, all is not lost. All three agree that fitness can benefit anyone. "You can pick it up at any age," Zukin says. "It's never too late as long as there's life and breath," Messinger says. Weckstein says it's easier to start a fitness program early in life "because then you get some good habits and it just becomes a natural thing to do. But at any time in your life, if you really want to change your life around and have a healthier life, you can make a change." Weckstein had good results with speedwalking classes for seniors from the Federa- tion apartments. "It's very beneficial. It gets them out; it gets them an ac- tivity.
