Isotemporal Substitution of Sedentary Time With Physical Activity Among Middle-Aged and Older Latinos: Effects on Episodic Memory.

Purpose: To examine the estimated effects of substituting 30 min of sedentary time with low-light physical activity (LLPA) and high-light physical activity (HLPA) on episodic memory, executive functioning, and working memory among middle-aged and older Latinos.

Design: A cross-sectional study.

Setting: Chicago and Chicagoland suburbs.

Relationships of Low Cognitive Performance and Sleep Disorder With Functional Disabilities Among Older Adults.

ObjectivesThis study examined the relationships of low cognitive performance and sleep disorder with functional disabilities among older adults. NHANES 2011-2014 data on 3179 individuals [M=69.71] were analyzed.

Effects of reducing sedentary behaviour duration by increasing physical activity, on cognitive function, brain function and structure across the lifespan: a systematic review protocol.

Introduction: Greater engagement in sedentary behaviours has been related to poorer cognitive functions in epidemiological research. However, the effects of reducing sedentary behaviour duration on cognitive function, brain function, and structure remain poorly understood. This systematic review aims to synthesise the evidence on the effects of reducing sedentary behaviour duration by increasing time spent in physical activity on cognitive function, brain structure and function in apparently healthy children, adolescents and adults.
