c WEDDING Castlépar News September 11, 1968 Leanne, daughter of Herb and Patti Teindl of Castlegar, was married to Aaron McKenzie, son of Joan McKenzie of Wartield, in June at our Lady of Perpetual Help Catholic Church in Trail. The couple is attending the University of Victoria Exercise helps quality of life By JUDY CREIGHTON Canadian Press Although there's no proof exercise can extend your life, there is mount ing evidence that physical fitness improves the quality of life and de- lays or prevents some of the degen erative changes of age In fact, research by the federal Department of Fitness has shown that exercise can even reverse many symptoms of advancing years “Many older adults cite health problems as something standing be- tween them and:a more active life," says a spokesman for the Secretariat for Fitness in the Third Age, a fed- eral agency in Ottawa. ‘Fortunately, there are very few people who can not — or should not — active than they are."’ And if you haven't indulged in regular physical activities for years, that shouldn't hold you back, says Scott Thoma, director of the Univer. sity of Toronto Sport Sciences Cen tre be more GET APPRAISAL Thomas says that before embark ing on a program of exercise — es pecially if-you've been sedentary for a while — you should have a fitness appraisal by a qualified technician, who can recommend a program suit- ed to your particular circumstances. These technicians often work through community recreation de- partments. ‘Most communities in Canada have someone who is qual ified either as a standardized test appraiser or certified fitness ap- praiser,"’ Thomas said It’s also wise to see your physician before significantly increasing the level of your activity ThoMias-said older people can en- joy walking, cycling, swimming, row- ing. jogging, ice-skating,cross-coun= try skiing and dancing “‘Walking is probably the best ex- because it seems to have fewer problems as far as accidents are concerned, and if you do it brisk- ly enough it can give a cardiovascular benefit."’ Sports and Fitness Ontario, part of the provincial Ministry of Tourism and Recreation, has a set of guide- lines specifically designed for older adults who want to get fit Begin any program slowly to avoid soreness or injury during the first few weeks. Before you begin any form of physical activity, including strenuous household chores such as snow shovelling or digging, it is important to do a 15-minute warm-up of stretching and slow walking ‘This step is needed to raise the temperature of your body and mus- cles and to permit greater flexibility and ease of movement,” the guide- lines state. ‘It lowers the chances of harmful muscle strain during the ex- ercise program.”’ Similarly, after your complete any physical activity, cool down by stret ‘ching and walking slowly for 15 minutes. This allows the circulatory ercise, system to return to normal Scientists look for perfection HALIFAX (CP) — Given a millen nium or two, nature engineered the human body from scratch. Now researchers at Dalhousie University want to stepin-where natpre falls down, impaired by old age and injury Their aim is to develop non-toxic materials for artificial implants, ranging from dental ¢rowns and joint replacements to prostheses and breast implants. “It's striving for perfection,” says Derek Jones, who heads the research group at Dalhousie. “Nature's been at it for several billion years, developing the struc tures of the body. It’s not easy to simulate naturab tissues ‘that will survive and function in the body.” Researchers in dentistry, chem istry and pharmacy are experi menting with glass, metals, ceramics and plastics in hope of developing a soft plastic which interacts well with the body and does not dissolve. The scientists are also building new materials from scratch in the lab oratory by putting molecules to gether Canada imports about $1.4 billion in medical and dental implants annually, said Jones, but many of the materials used in the implants are toxic or have no track record. “The vast majority have not been tested adequately for biological ef. fects”, he said. “We have analysed many plastic-based systems in dent istry and found they are really quite toxic.” Jones said experiments on ham. sters filled with implants indicate that many of the plastic materials available on the market are potent ially |cancer-causing, as they slowly dissolve in the body The have Dalhousie researchers now the funds to delve into the problem. They recently received a $721,591 grant from the Medical Research Council, a federally funded organization which promotes medical research. The funds come at a time when demand for implants worldwide is inereasing. For example, demand in Japan is growing by 50 per cent annually The research may also lead to the development of reliable temporary implants which allow the slow release of drugs into the body. “We are dealing with a rapidly aging population in North America where you get an elderly person who requires the slow release of a drug — and their ability to remember to take a tablet every four hours is not so sharp.” Jones also foresees economic spin offs. “You don't need a great big plant to be set up to create these implants,” he said. “It's high tech. nology that doesn’t require lots of expensive equipment. “The increasing future need for the use of artificial implants provides Dalhousie and Canada with an excellent opportunity to become leaders in the area during the next decade.” The Dalhousie group is forming a centre of excellence on bio-materials with researchers from other Nova Sentia universities. It plans to ask for additional funding after the grant runs out in three years. Medical studies aid children.
