AbstractNon-exercise physical activity (NEPA) and/or non-exercise activity thermogenesis (NEAT) reductions may occur from diet and/or exercise-induced negative energy balance interventions, resulting in less-than-expected weight loss. This systematic review describes the effects of prescribed diet and/or physical activity (PA)/exercise on NEPA and/or NEAT in adults. Studies were identified from PubMed, web-of-knowledge, Embase, SPORTDiscus, ERIC and PsycINFO searches up to 1 March 2017. Eligibility criteria included randomised controlled trials (RCT), randomised trials (RT) and non-randomised trials (NRT); objective measures of PA and energy expenditure; data on NEPA, NEAT and spontaneous PA; ≥10 healthy male/female aged>18 years; and ≥7 d length. The trial is registered at PROSPERO-2017-CRD42017052635. In all, thirty-six articles (RCT-10, RT-9, NRT-17) with a total of seventy intervention arms (diet, exercise, combined diet/exercise), with a total of 1561 participants, were included. Compensation was observed in twenty-six out of seventy intervention arms (fifteen studies out of thirty-six reporting declines in NEAT (eight), NEPA (four) or both (three)) representing 63, 27 and 23 % of diet-only, combined diet/exercise, and exercise-only intervention arms, respectively. Weight loss observed in participants who decreased NEAT was double the weight loss found in those who did not compensate, suggesting that the energy imbalance degree may lead to energy conservation. Although these findings do not support the hypothesis that prescribed diet and/or exercise results in decreased NEAT and NEPA in healthy adults, the underpowered trial design and the lack of state-of-the-art methods may limit these conclusions. Future studies should explore the impact of weight-loss magnitude, energetic restriction degree, exercise dose and participant characteristics on NEAT and/or NEPA.

ObjectiveTo examine the impact of acute classroom movement break (CMB) and physically active learning (PAL) interventions on physical activity (PA), cognition, academic performance and classroom behaviour.DesignSystematic review.Data sourcesPubMed, EBSCO, Academic Search Complete, Education Resources Information Center, PsycINFO, SPORTDiscus, SCOPUS and Web of Science.Eligibility criteria for selecting studiesStudies investigating school-based acute bouts of CMB or PAL on (PA), cognition, academic performance and classroom behaviour. The Downs and Black checklist assessed risk of bias.ResultsTen PAL and eight CMB studies were identified from 2929 potentially relevant articles. Risk of bias scores ranged from 33% to 64.3%. Variation in study designs drove specific, but differing, outcomes. Three studies assessed PA using objective measures. Interventions replaced sedentary time with either light PA or moderate-to-vigorous PA dependent on design characteristics (mode, duration and intensity). Only one study factored individual PA outcomes into analyses. Classroom behaviour improved after longer moderate-to-vigorous (>10 min), or shorter more intense (5 min), CMB/PAL bouts (9 out of 11 interventions). There was no support for enhanced cognition or academic performance due to limited repeated studies.ConclusionLow-to-medium quality designs predominate in investigations of the acute impacts of CMB and PAL on PA, cognition, academic performance and classroom behaviour. Variable quality in experimental designs, outcome measures and intervention characteristics impact outcomes making conclusions problematic. CMB and PAL increased PA and enhanced time on task. To improve confidence in study outcomes, future investigations should combine examples of good practice observed in current studies.PROSPERO registration numberCRD42017070981.

ObjectiveTo review and evaluate the impact of school-based, before-school physical activity (PA) programmes on children’s PA levels, health and learning-related outcomes.DesignSystematic review.Data sourcesPubMed, PsycINFO, Scopus, Embase and ERIC were searched in January 2021.Eligibility criteria for selecting studies(1) Original research published in English, (2) sample included typically developing school-age children and/or adolescents, (3) examined school-based PA programmes delivered before school, (4) included a comparator and (5) reported associations with PA, physical health, learning-related and/or psychosocial outcomes. Studies examining before-school active transport or sport were excluded.ResultsThirteen articles representing 10 studies were included (published 2012–2020); seven conducted in primary schools. Programmes ranged between 3 weeks and 6 months, primarily operating daily and for 25–40 min. One study examined a programme informed by theory; six incorporated fidelity measures. Data synthesis, considering consistency of findings, showed indeterminate associations for the domains of physical health, learning-related and psychosocial outcomes. Among subdomains, synthesis showed positive associations with before-school and daily PA, cardiorespiratory and muscular fitness, readiness to learn and an inverse association with adiposity. Risk of bias was high/serious or insufficiently detailed across studies and outcome domains, except PA, which included moderate-risk studies.ConclusionThere is limited available evidence on school-based, before-school PA programmes, with some positive associations at domain and subdomain levels. Continued research is justified to understand the role of before-school programmes for facilitating PA. Future research should follow recommended practice for intervention design and process evaluation, and address under-represented contexts, including secondary schools.PROSPERO registration numberCRD42020181108.

The experience and role of self-monitoring in self-directed weight loss attempts may be distinctly different from that within formal interventions, and has yet to be fully explored. We systematically reviewed qualitative studies to examine experiences of self-monitoring as an aid to self-directed weight loss. Thematic synthesis was used to construct descriptive and analytical themes from the available data. In all, 22 studies (681 participants) were included, in which the uses of self-monitoring ranged from an aid to increase adherence to a tool for facilitating analysis. Self-monitoring also influenced and was influenced by self-perception and emotions. Feelings of shame were linked with abandonment of efforts. Findings highlight the centrality of interpretation of self-monitored data, the implications this interpretation has on sense of self, and the impact of broader discourses. Explicitly framing self-monitoring as a positive tool with which to aid analysis may encourage helpful use of this technique.
