Dr. Perry works in the Kinesiology Department at York University. Kinesiology is about how the body moves. He teaches and does research. The research is particularly how diseases impact our muscles, such as cancer, aging and muscular distrophy. Muscles are plastic organs, the more they move the better they are. Healthy muscles means more strength. "You are what you do." How much exercise do we need? If we don't like word 'exercise' just get physical activity. A person age 18 to 64 should have 150 minutes a week of modest to vigorous activity - that means some sweat and hard breathing. That is about 1/2 hour, 5 days a week. A brisk walk. Not sitting all the time. He described benefits of healthy muscles: unrestricted ability to perform, cope with emergencies, reduced injuries, healthy aging, self esteem and self confidence. There is a lower risk of disease. As we age, we lose strength. Never too late. It doesn't take a lot of activity. Exercise is medicine, Especially with a good diet. Chris talked about the threshold of dependence. If we loose too much muscle strength, we loose our independence. Diseases can be prevented with exercise. Physical activity can prevent most of the 10 primary causes of death, including: Cancers Heart disease Acidents Influenza diabetes Alzheimers Suicide Exercise helps. With exercise, an over weight person can be healthier that a sedate thin person. Healthy Muscles = Healthy body = Healthy mind Do what you can. See the attached videos:
