Eii ,Exercise with caution in winter While winter is a time for added caution when exercising and doing $trenuous work, cold weather does not ean you need to discontinue your exercise program, says a University Medical Center exercise physiologist. ."We don't recommend that you lay Off your exercise program during the winter months," said Richard Lam- pman, who is also director of the University Medical Center's cardiac rehabilitation program in the Depar- tment of Internal Medicine. "IF YOU are a jogger, there is no 'eason for you to give up your running wuring the winter," Lampman con- tinued. "With the new materials for * lothing, you can exercise outside and otay warm and dry. Outdoor exercise during the winter can be beneficial and enjoyable - and the only major concern would be slipping on the ice." "One misconception about winter exercise is that breathing cold air is harmful to the lungs," Lampman said. "But the body warms the air as you breathe it sufficiently to prevent problems." f For those who do experience discomfort, Lampman recommends wearing a scarf over the nose and mouth to make breathing easier. Because of decreased daylight in the winter, reflective clothings should be Worn for safety, he added. He also suggests that the warm-up time before beginning to exercise be increased because of the colder New University researchers have developed a pill pacemaker, a new nonsurgical technique for tem- porarily pacing the heart to help diagnose cardiac illness and stabilize abnormally fast heartbeats. The technique avoids the time, cost, risk, and discomfort of inching a catheter electrode through a patient's vein to the heart - a surgical method of pacing that requires hospitalization. INSTEAD, AN electrode is placed inside a gelatin capsule the size of a cold pill. A fine thread of insulated vire is attached to the capsule. The patient swallows the capsule and the thread remains in the throat, the researchers said. The physician reels in the thread *ntil the pill reaches a point in the throat closest to the left atrium, the ipper left chamber of the heart. From this position, the heart can be stimulated with the pill electrode, usually for less than 30 minutes. It is got designed for long-term heart 'Anyone who is going to be working out- doors in the cold should avoid eating, drinking coffee or smoking just before going out.' -Richard Lampman, University exercise physiologist weather, and the cool down period af- ter exercising might be shortened slightly if performed outside or done inside. "YOU CAN walk around inside the house to cool down," he said. For those not inclined to run outdoors in the winter, Lampman recommends that other forms of aerobic exercises. "Brisk walking is good exercise, and you can do that inside a shopping mall in bad weather," he said. "For runners, there are indoor tracks in many communities where you can runfor a small fee," Lampman added. "Some schools allow jogging in their hallways after school in the winter." Indoor equipment, such as tread- mills, stationary bicycles with weighted flywheels, and rowing machines are also available and can provide good benefits, Lampman said. LAMPMAN recommends vigorous exercise - that which works the heart at 70 to 80 percent of its maximum rate - for at least 30 minutes three times a week. A person's maximum heart rate can be determined by subtracting his or her age from 220. A 40-year-old man, for instance, would have a maximum heart rate of 180 and should exercise to maintain a heart rate of about 125 to 145 for 30 minutes for maximum benefit. Lampman cautions, however, that strenuous outdoor activities in cold weather can be dangerous for people who are at risk for heart problems. "Each year, we see cases of men with no history of heart disease having heart attacks while shoveling snow,"he said. SHOVELING snow or attempting to push a car which is stuck in the snow are especially dangerous, Lampman said. Cold weather tends to constrict the blood vessels in some people with underlying heart disease, increasing blood pressure and forcing the heart to work harder and increasing its need for oxygen, he explained. The contraction in the muscles of the trunk caused by shoveling snow or pushing a stuck automobile further tends to increase blood pressure, and people also have a tendency to hold their breath while lifting or pushing with the arms, Lampman continued. The risk is particularly great for men with heart problems or high blood pressure, or for those who are over 40 with known risk factors such as high blood cholesterol or fat levels, diabetes or who are overweight, Lampman said. "Anyone who is going to be working outdoors in the cold should avoid eating, drinking coffee or smoking just before going out," Lampman ad- ded. The digestion of food and caffeine in coffee add to the heart's load. Smoking loads the red blood cells down with carbon monoxide and reduces the amount of oxygen the cells can carry. "All of this makes the heart work harder," Lampman said. "adding to the strain from shoveling snow and potentially over burdening the heart and causing a heart attack." 3.

The pill device can help evaluate patients with coronary artery disease because their heartbeats must be ac- celerated before being analyzed, said Prof. Janice Jenkins of the Univer- sity's Department of Electrical Engineering and Computer Science. Traditionally, patients have been placed on a treadmill or subjected to some other exercise to elevate their pulse. Transesophageal atrial pacing allows complete control of the heart rate independent of patient perfor- mance and can be used in patients who are physically unable to achieve intense levels of exercise. THE PRECISE heart control provided by the pill electrode and its ability to accelerate the pulse without moving the patient combine to help produce crisper images of the heart using such devices as X-ray or nuclear cameras, which rely on the hearbeat to trigger their exposures, Jenkins said. The pill electrode also can be used to stabilize abnormally elevated hear- tbeats through overdive pacing, a method of correcting atrial flutter and other abnormally fast heartbeats by aaccelerating the heart electrically, then slowing the rate. In many cases, a normal heart rhythm will result. "Transesophageal overdrive pacing offers - several advantages: the technique offers virtually univer- sal noninvasive access to the atrium; it can be performed in an outpatient setting; it requires minimal or no sedation; and there is little discom- fort," Jenkins said. The pill pacemaker also serves as a comfortable alternative to an elec- trode catheter inserted-through the nasal cavity and into the throat, another method of transesophageal atrial pacing. The University is at the forefront of research and clinical trials on the device, Jenkins said. In earlier trials, 43 of 46 patients who consented to the transesophageal pill method were successfully paced either to stabilize an irregular heartbeat or obtain an image of the heart for diagnosis. "There were no reports of discom- fort in swallowing or positioning the pill electrode, and high quality recor- dings were obtained in all cases without difficulty," said Jenkins, who was assisted on the project by Mac- donald Dick and William O'Neill, University Medical Center car- diologists. PATIENTS DID complain, however, of a sensation of moderate to severe heartburn that vanished immediately when pacing was halted, she said. In a related project, Jenkins, Kevin Gage, Jenkins' laboratory manager, and C.E. , Yurkonis, a research engineer with Arzco Medical Elec- tronics Inc., have designed a com- puter program to automatically con- trol the intensity and duration of elec- trical currents a physician wants from a heart pacer. The program would be most useful in an emergency room where doctors could save the time needed to make those settings manually.

"You don't look 40," they insisted. "Nonsense," the feminist retorted. This is what 40 looks like." AGE, like beauty, is in the eye of the eholder. Aging not only looks dif- erent but feels different, depending ipon one's life circumstances, a niversity researcher contends. f Women of various racial 1ackgrounds have dissimilar percep- lions of aging, according to Evelyn Barbee, assistant professor of nursing and anthropology, and the author of a tiew cross-culteral study comparing low-income black women and low- income white women at mid-life. " "Black women tend to have more positive feelings about growing older. They value their present age for the tollective wisdom and maturity it brings. But the pleasure is accom- panied by greater health problems and mental exhaustion," she reports. "The white women in the survey were more likely to mention the ad- vantages of freedom and time for themselves after the children were grown. On the negative side, they worried more about their husband's health." SIMILARITIES between the two groups emerged as well. Both chose 32 as the ideal age for a woman to be, and all said they would like to be, on the average, eight years younger than their current age, Barbee said. She focused her study on 107 black and 100 white low-income women between the ages of 32 and 56 living int the Detroit area. Thirty-two percent of the black women and 58 percent of the white women were married, and * APPENINGS- Highlight Soprano Jessye Norman will perform tonight at 8 p.m. at Hill Auditorium.

"The goals were to determine which perceptions"of aging are culturally in- fluenced, and which were universal," she explained. "In addition: What stressors make women feel older than their chronological age? Do the two groups experience different signs and symptoms of aging? How does the immediate family and greater social environment affect their feelings about growing older?" Although the data is still being analyzed, some early trends are evident. For example, both black and white women who report being under stress feel older than their chronological age and express a desire to be much younger. Those who said they felt older than their actual age also said that they expec- ted to die younger, Barbee said. IN THE category of aging signs and symptoms, about 72 percent of the black women and 50 percent of the white women said their weight and body were better five years ago. "Black women do not necessarily view weight gain as being as unhealthy and unattractive as white women do," Barbee adds. The black women had more children at home, and six were rearing their grandchildren, even though only half as many blacks as whites were married. Both groups reported similar stressful events or situations such as family illnesses, deaths of someone close, household moves, burglaries, and drug and alcohol problems. Although all women in the study qualified as "low income," black women averaged $10,000 per year while white women reported a median XA le and send you on your way.
