Regular physical activity (PA) is beneficial for cognitive health, and cathepsin B (CTSB) - a protease released by skeletal muscle during PA - acts as a potential molecular mediator of this association. PA-induced metabolic and mechanical stress appears to increase plasma/serum CTSB levels. CTSB facilitates neurogenesis and synaptic plasticity in brain regions (e.

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.

- Meeting 24-hour movement behaviors (physical activity, screen time, and sleep) is linked to better health outcomes for youth with mental, behavioral, and neurodevelopmental conditions, but trends and disparities in adherence have not been thoroughly explored.
- A study analyzed data from over 52,000 U.S. youth (ages 6-17) from 2016 to 2021, revealing a decline in meeting all movement behavior guidelines while more youth reported not meeting any guidelines.
- Findings showed variations by factors like age, sex, and ethnicity, emphasizing the need for targeted health interventions for at-risk youth populations.
Objective: To examine the acute and chronic effects of reducing prolonged sedentary time (ST) with physical activity (PA) on cognitive and brain health.
Design: Systematic review and meta-analysis.
Data Sources: PubMed, Scopus, CINAHL, PsycINFO, SPORTDiscus, Web of Science, and ProQuest Dissertation and Theses.

Background: and Purpose: Outdoor play is widely acknowledged for its benefits to physical health and psychological well-being, yet its relationship with school readiness remains understudied in preschoolers. To address this gap in the literature, this study investigated how outdoor play relates to cognitive and psychosocial development among a nationally representative sample of preschoolers.
Materials And Method: Data on the duration of outdoor play (on weekdays and weekends) and specific cognitive and psychosocial outcome variables (i.
