EXERCISE UPDATE NEWS cognition in elderly Activity boosts
Moderate or high physical activity appears to be associated with a lower risk of developing cognitive impairment in older adults after a two-year period, according to a study involving nearly 4,000 people older than 55, from southern Bavaria.
At the beginning of the study, 418 participants (10.7 per cent) had cognitive impairment. After two years, 207 (5.9 per cent) of the remaining 3,485 unimpaired study participants developed cognitive impairment. “The incidence of new cognitive impairment among participants with no, moderate and high activity at baseline was 13.9 per cent, 6.7 percent and 5.1 per cent, respectively,” the authors write.

Energy expenditure protects from brain cancer
It now seems that energy expenditure in childhood could protect you from a rare but often deadly form of brain cancer. Researchers from the National Cancer Institute have found that the occurrence of this particularly deadly form of brain cancer, which accounts for nearly 80 per cent of brain and nervous system cancers, may be linked to early life physical activity and height.
Dr Steven Moore, a research fellow in the Nutritional Epidemiology Branch of the National Cancer Institute said, “Our findings suggest that biological factors related to energy expenditure and growth
during childhood may play a role in glioma etiology. This clue could help researchers better understand important features of glioma biology and the potentially modifiable lifestyle factors that could be important in preventing this disease. He added, “engaging in regular physical activity throughout the lifespan conveys many benefits.” Results of this prospective study have been published online first in the American Association for Cancer Research’s journal, Cancer Research.
