Exercise For Chronic Disease Prevention

The beneficial health effects of exercise—including reduced risk of heart disease, stroke and type 2 diabetes—are well known, but the underlying biological mechanisms of these benefits are unclear. A new study takes a look at how regular exercise impacts health and metabolism. Using a system that analyzes blood samples, Massachusetts General Hospital (MGH) researchers have developed a "chemical snapshot" of the metabolic effects of exercise. Their findings may improve understanding of the physiologic effects of exercise and may help develop new therapies for cardiovascular disease and diabetes. . The study appears in the May issue of Science Translational Medicine. "We found new metabolic signatures that clearly distinguish more-fit from less-fit individuals during exercise," says study author Gregory Lewis, M.D., of the MGH Heart Center. "These results have implications for the development of optimal training programs and improved assessment of cardiovascular fitness." Benefits of exercise: • Prevents chronic disease. • Aids in weight management. • Boosts energy level. • Regulates sleep patterns. • Lowers blood pressure. After exercising, participants who were more fit had a 98 percent increase in the breakdown of stored fat, sugar and amino acids, while less-fit people had only a 48 percent increase. "Our results have implications for development of both diagnostic testing to track and improve exercise performance and for interventions to reduce the effects of diabetes or heart disease,” says study author Robert Gerszten, M.D. … Read More

Diet And Exercise For Health

A healthy diet and regular exercise may help the mind function better, a new Duke University study suggests. “It looks like exercise and diet improve the range of cognitive function,” says Patrick Smith, a clinical neuropsychology intern and research member. “It helps executive function, learning and psychomotor speed.” The study assessed 124 men and women with high blood pressure who were at least 15 pounds overweight, determining the effect of diet and exercise on blood pressure. Those participants that ate well and exercised regularly had an overall 30 percent improvement in mental function by the end of the four-month period, the researchers noted. Strategies utilized were a weight management program which included appetite awareness training, reduced portion size, following the low-fat DASH diet (Dietary Approaches to Stop Hypertension), and healthy snacking habits, combined with aerobic exercise workouts for 30 minutes three to four times a week. “Physical activity does seem to have a direct effect on brain cells,” says Smith. “There are neurochemical changes that happen with exercise. There is also some evidence that it helps grow new brain cells.” Cognition can be improved by: • Memory exercises. • Stress reduction. • Including vitamin E, vitamin C, beta carotene, and other antioxidants in the diet. • Ensuring adequate sleep. Acupuncture & Massage College’s Community Clinic offers acupuncture, Chinese herbal medicine and massage therapy for weight loss as well as a wide range of other health conditions.
