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.

Objective: There is evidence that complex relationships exist between motor functions, brain structure, and cognitive functions, particularly in the aging population. However, whether such relationships observed in older adults could extend to other age groups (e.g.

Article Synopsis
  • 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.

Team-based physical activity (PA) can improve social cognition; however, few studies have investigated the neurobiological mechanism underlying this benefit. Accordingly, a hyper-scanning protocol aimed to determine whether the interbrain synchrony (IBS) is influenced by an acute bout of team-based PA (i.e.

Background: The 24-hour movement behavior (24-HMB) guidelines recommend that children and adolescents (youth) should limit screen time (ST), get an adequate amount of sleep (SL), and engage in sufficient physical activity (PA) to ensure health and healthy development. Meeting 24-HMB guidelines is associated with positive mental health outcomes (e.g.

Article Synopsis
  • The dopaminergic system, crucial for cognitive functions, is affected by physical activity (PA).
  • Recent evidence suggests that changes in this system due to PA can impact cognitive performance.
  • The text discusses advancements in research and identifies current challenges and opportunities for future studies in this area.

Article Synopsis
  • A study investigated the mental health benefits of meeting 24-hour movement behavior (24-HMB) guidelines among children and adolescents who wear glasses or contact lenses.
  • Using data from a national survey with over 6,000 participants, researchers found that only a small percentage met all three movement guidelines (physical activity, sedentary behavior, and sleep).
  • However, meeting at least two of these guidelines was associated with significantly lower odds of internalizing and externalizing problems, suggesting the need for targeted interventions to promote healthier behaviors in this population.

Background: The Canadian 24-hour movement behavior (24-HMB) guidelines recommend an adequate level of physical activity (PA), a limited amount of screen time (ST), and a sufficient sleep duration (SLP) to promote the healthy development of children. Although the positive effects of adhering to the 24-HMB guidelines have been established for several health parameters, less is known about how adherence to the 24-HMB guidelines relates to the myopia risk (i.e.

Objective: The current study aimed to examine the effects of a mindfulness group intervention on self-compassion, psychological resilience, and mental health of children from single-parent families in Tibetan areas.

Methods: A total of 64 children from single-parent families in Tibetan areas were randomly allocated to a control group (n = 32) and an intervention group (n = 32). Participants in the control group received conventional education, while participants in the intervention group received 6-week mindfulness intervention in addition to the conventional education.
