Effect of hypoxic exercise on atrial natriuretic factor and aldosterone regulation.

abstract：BACKGROUND:Research on associations between blood pressure, brain structure, and cognitive function has produced somewhat inconsistent results. In part, this may be due to differences in age ranges studied and because of sex differences in physiology and/or exposure to risk factors, which may lead to different time cou...
