Cardiorespiratory Fitness May Protect Memory for Poorer Sleepers

OBJECTIVES: Physical activity has been shown to protect executive functions against the deleterious effects of poorer sleep among older adults (OA); however, it is unknown whether memory is protected too, and if this relationship differs by age. The present study investigated the relationship between cardiorespiratory fitness, sleep, and memory in both older and young adults (YA). METHODS: This observational study recruited 26 OA (70.7 ± 2.8 …
