TL;DR: Serum β-hydroxybutyrate, serum acetoacetate, and urine ketone concentrations increased from rest following ketone ingestion and were higher than placebo throughout the trial.
Abstract: We investigated the effect of pre- "race" ingestion of a 1,3-butanediol acetoacetate diester on blood ketone concentration, substrate metabolism and performance of a cycling time trial (TT) in professional cyclists. In a randomized cross-over design, 10 elite male cyclists completed a ~31 km laboratory-based TT on a cycling ergometer programmed to simulate the 2017 World Road Cycling Championships course. Cyclists consumed a standardized meal [2 g/kg body mass (BM) carbohydrate (CHO)] the evening prior to a trial day and a CHO breakfast (2 g/kg BM CHO) with 200 mg caffeine on the morning of a trial day. Cyclists were randomized to consume either the ketone diester (2 × 250 mg/kg) or a placebo drink, followed immediately by 200 mL diet cola, given ~ 30 min before and immediately prior to commencing a 20 min incremental warm-up. Blood samples were collected prior to and during the warm-up, pre- and post- TT and at regular intervals after the TT. Urine samples were collected pre- and post- warm-up, immediately post TT and 60 min post TT. Pre-exercise ingestion of the diester resulted in a 2 ± 1% impairment in TT performance that was associated with gut discomfort and higher perception of effort. Serum β-hydroxybutyrate, serum acetoacetate, and urine ketone concentrations increased from rest following ketone ingestion and were higher than placebo throughout the trial. Ketone ingestion induces hyperketonemia in elite professional cyclists when in a carbohydrate fed state, and impairs performance of a cycling TT lasting ~50 min.

TL;DR: Toddlers and pre-schoolers with space to play at home and living in rural areas experienced an attenuated impact of the pandemic restrictions on their physical activity levels, screen time, and sleep quality.
Abstract: The aim was to examine the sociodemographic predictors associated with changes in movement behaviors (physical activity, screen time, and sleep) among toddlers and preschoolers during the early stages of the coronavirus disease 2019 pandemic in Chile. Caregivers of 1- to 5-year-old children completed an online survey between 30 March and 27 April 2020. Information about the child's movement behaviors before (retrospectively) and during the pandemic, as well as family characteristics were reported. In total, 3157 participants provided complete data (mean children age: 3.1 ± 1.38 years). During early stages of the pandemic, time spent in physical activity decreased, recreational screen time and sleep duration increased, and sleep quality declined. Toddlers and preschoolers with space to play at home and living in rural areas experienced an attenuated impact of the pandemic restrictions on their physical activity levels, screen time, and sleep quality. Older children, those whose caregivers were aged ≥35-<45 years and had a higher educational level, and those living in apartments had greater changes, mainly a decrease in total physical activity and increase in screen time. This study has shown the significant impact of the pandemic restrictions on movement behaviors in toddlers and preschoolers in Chile.

TL;DR: In this paper, the authors present discussion from a diverse range of research settings which includes Sweden, Iceland, Italy, Northern Ireland, the United Kingdom and Australia, and the underlying philosophy of each article is that all young children have the competence to engage in research as sophisticated thinkers and communicators and the inclusion of children's views are pivotal if we are to understand their life worlds.
Abstract: Over recent years, there has been increasing attention to the importance of involving children and listening to their voices and perspectives in research. The purpose of this monograph is to draw upon exemplary research with young children that is being undertaken in partnership with academics across the globe. The articles also seek to examine some of the critical issues and ethical dilemmas in this unique research paradigm. We are pleased to present discussion from a diverse range of research settings which includes Sweden, Iceland, Italy, Northern Ireland, the United Kingdom and Australia. The underlying philosophy of each article is that all young children have the competence to engage in research as sophisticated thinkers and communicators and that the inclusion of children's views are pivotal if we are to understand their life worlds.

TL;DR: In this article, the importance of reflective metacognitive activity during mathematical modelling activity has been recognised by scholars and researchers over the years. And the authors discuss the role of reflective meta-metacognition in the identification and release of blockages to progress.
Abstract: The importance of reflective metacognitive activity during mathematical modelling activity has been recognised by scholars and researchers over the years. The metacognitive activity (or lack of it) of secondary students associated with transitions between stages in the modelling process – especially in relation to the identification and release of blockages to progress – is considered. Productive metacognitive acts are identified as occurring at three levels. Routine metacognition together with metacognitive responses to Goos’ red flag situations are elaborated together with the notion of meta-metacognition being engaged in by teachers trying to foster students’ development of independent modelling competencies especially their metacognitive competencies.
