Washington: Exercise doesn`t only strengthen your heart and muscles - it also helps increase brain power, say researchers. Dozens of studies now show that aerobic exercise can increase the size of critical brain structures and improve cognition in children and older adults, according to University of Illinois psychology professor Art Kramer, a nationally recognized expert on the role of physical fitness on cognition."Populations throughout the industrialized world are becoming increasing sedentary as a result of the changing nature of work and leisure activities. As a result of these societal changes, increases in diseases such as hypertension, diabetes, osteoporosis and some cancers are increasing. Physical activity serves to reduce susceptibility to these diseases," Kramer said."Increased physical activity also has direct, and relatively rapid effects on cognition and brain health," he added.
