  This study aimed to evaluate the effects of high-intensity training (HIT) on salivary cortisol levels in physically trained individuals. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The search for scientific articles was carried out on the Scopus and MEDLINE (via PubMed) databases with the terms resistance training, saliva, cortisol, and their synonyms. We included interventions with high-intense resistance training that analyzed the salivary cortisol levels in physically trained men and women. From the 399 articles found, eight studies met the inclusion criteria. A population of 135 physically trained men and 12 women is with an average age of 23.26 ± 3.10 years, body mass of 85.53 ± 12.68 kg, and height of 1.80 ± 0.04 m. The intervention period ranged from 3 to 15 weeks with the use of 1 to 5 sets of 5 to 10 repetitions. Most protocols have been shown to provide significant stimuli to increase the level of cortisol acutely (p<0.05). The practice of HIT seems to be an effective intervention to stimulate the increase in acute and chronic salivary cortisol levels and thus induce possible changes in physiological and hormonal levels. Moreover, cortisol seems to represent physical activity in some populations and may be useful in monitoring physiology in large-scale observational physical activity surveys. However, more research is needed to elucidate the effects of HIT on cortisol and adaptive results. Resumen. Este estudio tuvo como objetivo evaluar los efectos del entrenamiento de alta intensidad sobre los niveles de cortisol salival en individuos entrenados físicamente. Esta revisión sistemática siguió las recomendaciones de PRISMA. La búsqueda de artículos científicos se realizó en las bases Scopus y MEDLINE (vía PubMed) con los términos entrenamiento de resistencia, saliva, cortisol y sus sinónimos. Se incluyeron intervenciones con entrenamiento de resistencia de alta intensidad que analizaron los niveles de cortisol salival en hombres y mujeres entrenados físicamente. De los 399 artículos encontrados, ocho estudios cumplieron los criterios de inclusión. Una población de 135 hombres entrenados físicamente y 12 mujeres tiene una edad de 23,26±3,10 años, masa corporal de 85,53±12,68 kg y altura de 1,80±0,04 m. El período de intervención varió de 3 a 15 semanas con el uso de 1 a 5 series de 5 a 10 repeticiones. Se ha demostrado que la mayoría de los protocolos proporcionan estímulos significativos para aumentar el nivel de cortisol de forma aguda (p<0,05). La práctica de entrenamiento de alta intensidad parece ser una intervención eficaz para estimular el aumento de los niveles de cortisol salival agudo y crónico y así inducir posibles cambios en los niveles fisiológicos y hormonales. Además, el cortisol parece representar la actividad física en algunas poblaciones y puede ser útil para monitorear la fisiología en encuestas observacionales de actividad física a gran escala. Sin embargo, se necesita más investigación para dilucidar los efectos de entrenamiento de alta intensidad sobre el cortisol y los resultados adaptativos.

Objective To evaluate the relationship between grandparenting and the cognitive impairment in older persons.Methods The protocol was submitted to the International Prospective Register of Systematic Reviews (PROSPERO), registration number: CRD42018105849. Authors conducted a systematic review, following “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA) recommendations. Electronic databases were accessed through august 2018: PubMed, ISI Web of Knowledge, Scopus, and EBSCOhost. Selection of records and quality appraisal were made by two reviewers, independently.Results A total of 178 records was found, after removing duplicates. From those, 17 were considered eligible for integral text reading and eight were included: five original studies, one classic review and two editorials. From the five original studies included, four suggested a positive effect on cognition resulting from grandparenting and one suggested that there was no evidence for a causal effect. Though the boundary was not consensual, some studies suggested that a higher frequency of grandparenting has a negative impact on cognition.Conclusion Overall, studies suggested a trend towards a positive effect of grandchild care on grandparents’ cognition. However, there was a significant heterogeneity between methodologies and a significant risk of bias which can hamper conclusions, indicating the need for further and more robust research.

El objetivo de esta revisión sistemática ha sido analizar la influencia de la posesión del balón en el rendimiento físico de los equipos y los jugadores en el fútbol masculino de elite. Se realizó una búsqueda sistemática de artículos relevantes en inglés en una base de datos (Web of Science Core Collection) y un motor de búsqueda (PubMed) siguendo el protocolo de PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Las palabras clave “association football” y “soccer” se relacionaron con los términos: “possession of the ball”, “possession” “physical activity” y “physical performance”. Se buscaron estudios empíricos relacionados con el rendimiento físico y la posesión del balón para su inclusión y análisis. Se revisó el texto completo de 21 estudios. Globalmente, tener un alto (51–66%) o bajo (34–50%) porcentaje de posesión del balón produce diferencias muy poco relevantes en las distancias recorridas por los jugadores. Tan sólo la distancia cubierta con y sin la posesión del balón es significativamente diferente. Además, no está claro que correr más o menos pueda asociarse con un incremento de las probabilidades de ganar o perder.

IntroductionObesity and being overweight are major risk factors for metabolic syndrome and non-communicable diseases. Despite the recommendation that a healthy diet and physical activity can reduce the severity of these diseases, many fail to adhere to these measures. From a behavioural economic perspective, adherence to such measures can be encouraged through financial incentives. However, additional related behavioural economic approaches may improve the effectiveness of an incentive programme. As such, we have developed a protocol for a systematic review and network meta-analysis to summarise the current evidence from financial incentive programmes with and without behavioural economic insights for promoting healthy diet and physical activity.Methods and analysisPrevious systematic reviews, meta-analyses and individual studies were identified from Medline and Scopus in June 2020 and will be updated until December 2020. Individual studies will be selected and data extracted by two reviewers. Disagreement will be resolved by consensus or adjudicated by a third reviewer. A descriptive analysis will summarise the effectiveness of behavioural economic incentive programmes for promoting healthy diet and physical activity. Moreover, individual studies will be pooled using network meta-analyses where possible. I2 statistics and Cochran’s Q test will be used to assess heterogeneity. Risk of bias and publication bias, if appropriate, will be evaluated, as well as the overall strength of the evidence.Ethics and disseminationEthics approval for a systematic review and meta-analysis is not required. The findings will be published in a peer-reviewed journal.PROSPERO registration numberCRD42020198024.

IntroductionChildren are one of the most vulnerable groups in disasters. Improving students’ knowledge and skills to prepare for disasters can play a major role in children’s health. School as a place to teach children can make a significant contribution to provide the necessary skills. This study aims to identify the effects, strengths and weaknesses of interventions in schools to prepare children for disasters.Methods and analysisWe use Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to develop a protocol for this systematic review. The included studies will report on the results of interventions targeting ‘schoolchildren’ defined as individuals between 4 and under 18 years old studying in schools. Different electronic databases will be used for a comprehensive literature search, including MEDLINE, Web of Science, CINAHL, PsycINFO, Cochrane Register of Controlled Trials and EMBASE to identify the records that match the mentioned inclusion criteria published till December 2020. The main search terms are ‘disaster’, ‘preparedness’, ‘children’ and ‘school’. Four types of data will be extracted from the qualified studies including study characteristics (study design, year of publication and geographical region where the study was conducted), participant characteristics (sample size, age and gender), intervention characteristics (aim of intervention, intervention facilitators and barriers) and intervention outcomes. The quality appraisal of the selected papers will be conducted using Cochrane Collaboration’s Risk of Bias for quantitative studies and Critical Appraisal Skills Programme checklist for qualitative studies. We use a narrative synthesis for this systematic review. The narrative synthesis refers to an approach to systematic reviews which focuses mostly on applying words and texts to summarise and explain findings.Ethics and disseminationThis paper is a part of a Ph.D. thesis of Hamed Seddighi at University of Social welfare and Rehabilitation Sciences with ethics code IR.USWR.REC.1399.008 approved by the Ethics Committee of the above-mentioned university.PROSPERO registration numberCRD42020146536.

The Impact

Confinement at home, quarantine, and social distancing are some measures adopted worldwide to prevent the spread of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-Cov-2), which has been generating an important alteration in the routines and qualities of life of people. The impact on health is still being evaluated, and consequences in the nutritional field are not entirely clear. The study objective was to evaluate the current evidence about the impact that preventive measures of physical contact restriction causes in healthy nutrition. A systematic review was carried out according to the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” PRISMA Group and Cochrane method for rapid systematic reviews. Searching was performed in six electronic databases and evaluated articles published between 2010 and 2020, including among their participants adult subjects who had been exposed to the preventive measures of physical contact restriction. Seven studies met the selection criteria and reported an overall increase in food consumption, weight, Body Mass Index (BMI), and a change in eating style. Findings suggest that healthy nutrition is affected by preventive measures to restrict physical contact as a result of the COVID-19 syndemic.
