Effectiveness of exercise interventions, alone or in combination with dietary modifications, on working memory in overweight and obese individuals: A systematic review.
Eur J Sport Sci
September 2024
Article Synopsis
- * A total of 15 studies were included, with findings showing that 70% of exercise-only interventions and 60% of combined exercise and diet interventions led to improved WM, indicating both methods can be beneficial.
- * Despite promising results, the limited number of studies combining exercise and diet suggests caution in generalizing the findings, highlighting the need for more research in this area for better clinical applications.
Substantial parallel mediation contribution by cognitive domains in the relationship between adolescents' physical fitness and academic achievements: the Cogni-Action Project.
Front Psychol
July 2024
Article Synopsis
- The study examined how cognitive abilities (working memory, inhibitory control, and fluid reasoning) influence the relationship between physical fitness and academic success in adolescents aged 10-14.
- It involved 1,296 participants, and measured fitness through a test battery while academic achievement was assessed across five subjects.
- Findings revealed that cognitive domains fully mediated the fitness-academic performance link for Language and English, while showing partial mediation for other subjects, highlighting the importance of mental skills in educational outcomes.
Article Synopsis
- Sedentary behavior is linked to negative health effects, and "The Up Project" aims to evaluate the effectiveness of two interventions—professional-led active breaks and self-led computer prompts—compared to a control group among office workers.
- The study will involve 60 desk-based workers in Valparaiso, Chile, over 12 weeks, measuring various health indicators like cardiometabolic risk, physical activity, and stress perception at the start and end of the intervention.
- The research highlights the need for more comprehensive studies on different protocols to address health issues stemming from sedentary lifestyles, particularly for office workers.
A Mediterranean diet (MedDiet) has emerged as a crucial dietary choice, not only in attenuating various adolescents' metabolic health issues but it has also been associated with improved cognitive and academic achievement. However, few studies have established patterns of food consumption linked to both cognitive and academic achievement in adolescents living in a developing country with non-Mediterranean-based food. This cross-sectional study included 1296 Chilean adolescents (50% girls) aged 10-14 years.

Objective: This study compares physical fitness components and waist-height-to-ratio (WHtR) in adolescents according to school uniforms, namely the traditional uniform (i.
Objective: The objective of this study was to compare the levels of sedentary behaviour and physical activity in relation to sociodemographic variables of Chilean schoolchildren before and during the COVID-19 pandemic.
Methods: This retrospective study considered a non-random sample of 83 boys and 232 girls, and their respective parents, who attended public schools ( = 119) and private schools ( = 196) in Chile. A self-report instrument was applied that included sociodemographic variables, sedentary behaviour (SB), and physical activity (PA) in the second period of the pandemic in 2021.
Background: Kidney diseases are a public health problem worldwide. Available therapies include function replacement by dialysis or transplant, which are associated with a high morbidity and mortality. Likewise, none of these treatments compensate all kidney functions.
