The short-term effects of sedentary behaviour on cerebral hemodynamics and cognitive performance in older adults: a cross-over design on the potential impact of mental and/or physical activity

摘要

Study Design. Study design, with four conditions shown horizontally. During SIT- people stayed seated for three hours while watching television. In the BREAK- condition people interrupted their television watching with two-minute walking breaks.

Before and after each condition measurements were conducted
