Acknowledging the detrimental effects of prolonged sitting, this study examined the effects of an acute exercise break during prolonged sitting on executive function, cortical hemodynamics, and microvascular status. In this randomized crossover study, 71 college students completed three conditions: (i) uninterrupted sitting (SIT); (ii) SIT with a 15 min moderate-intensity cycling break (MIC); and (iii) SIT with a 15 min vigorous-intensity cycling break (VIC). Behavioral outcomes, retinal vessel diameters (central retinal artery equivalents [CRAE], retinal vein equivalents [CRVE], arteriovenous ratio [AVR]), cortical activation, and effective connectivity were evaluated.

Exercise is an evidence-based strategy to prevent falls, but whether exercise reduces falls in people with cognitive frailty is unknown. We examined the effects of home-based exercise on subsequent falls among community-dwelling older adults with cognitive frailty who have previously fallen.

Methods: A 3-arm parallel randomized clinical trial among community-dwelling adults aged 55+ years with chronic stroke (ie, ≥12 months since stroke).
Introduction: One-third of adults aged 65+ fall annually. Injuries from falls can be devastating for individuals and account for 1.5% of annual healthcare spending.

- Prolonged bed rest negatively impacts health, particularly cognitive performance in middle-aged and older adults, making it essential to explore exercise as a remedy.
- A study involved 23 healthy adults aged 55-65, comparing 14 days of bed rest with and without daily exercise, assessing cognitive function using standardized tests.
- Results indicated that those who exercised during bed rest had significantly better cognitive performance (lower variability) than those who did not, with a notable difference based on sex in the effects of exercise.
