Preventing declines in cerebral blood flow is important for maintaining optimal brain health with aging. We compared the effects of a morning bout of moderate-intensity exercise, with and without subsequent light-intensity walking breaks from sitting, on cerebral blood flow velocity over 8-hours in older adults. In a randomized crossover trial, overweight/obese older adults (n=12, 2♀, 70±7 years; 30.4±4.3 kg/m2 ), completed 3 acute conditions (6-day washout); SIT: prolonged sitting (8hr, control); EX+SIT: sitting (1hr), moderate-intensity walking (30min), followed by uninterrupted sitting (6...
