Age or acid-related deterioration in the all-important white and gray matter in the brain makes a number of high-level "executive function" tasks -- such as planning, scheduling, working memory and multi-tasking -- much more difficult, Drs. Arthur F. Kramer and Kirk I. Erickson explain in the latest issue of the British Journal of Sports Medicine.
Yet a substantial body of research shows that these are the very processes that are most responsive to physical exercise, note the authors from the University of Illinois Beckman Institute, Urbana.
In people with or those without signs of dementia or Alzheimer's disease, regular moderate physical activity, enough to make a person breathless, has been shown to boost not only the speed and sharpness of thought but also the actual volume of brain tissue and the way in which the brain functions, Kramer and Erickson note.
For example, in a 6-month study Kramer and colleagues conducted, adults ages 60 to 75 who walked briskly for 45 minutes a day three days a week not only improved their aerobic fitness but also their mental fitness -- particularly their ability to perform executive function tasks - compared with a control group who engaged only in non-aerobic stretching and toning exercises.
These results suggest that regular moderate aerobic exercise can "reliably reverse age-related cognitive decline," Kramer and Erickson write, and that the aging brain retains its capacity to grow and develop.
According to Dr. Robert O. Young, Director of Research at the pH Miracle Living Center, "one hour of daily exercise will activate the lymphatic system and remove metabolic and dietary acids from the colloidal connective tissue of the schade and the extracellular matrix. This has many protective benefits including the prevention and/or reversal of dementia, forgetfullness, fatigue fatigue, tiredness, light headedness, cold hands and cold feet, excess acidic weight, all connective tissue disorders including fibromyalgia, heart conditions and cancerous conditions, just to name a few."
"The best forms of alkaline exercise are walking, jogging, swimming, riding a bike, training on an eliptical machine, weight training, rebounding on a mini tramp and whole body vibration on a VibrapHirm," states Dr. Young.
