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.

The study aimed to identify the sources of information that athletes perceive as influential during their initial evaluation of coaching ability. University athletes (N = 538) were asked to indicate the influence of 31 informational cues (e.g., gender, body language or gestures, reputation) on the initial impression formed of a coach. Following exploratory factor analysis, a 3-factor model (i.e., static cues, dynamic cues, and third-party reports) was extracted. Mean scores revealed that although static cues (e.g., gender, race or ethnicity) were rated as relatively unimportant during impression formation, dynamic cues (e.g., facial expressions, body language or gestures) and third-party reports (e.g., coaching qualifications, reputation) were viewed by athletes as influential factors in the formation of expectancies about coaches. Such findings have implications for the occurrence of expectancy effects in coach−athlete relationships and the way in which coaches seek to present themselves.

The study aimed to investigate the impact of coach reputation and gender on athletes' expectancies of coaching competency. Male and female athletes (n = 304) viewed a coach profile (i.e., photograph and brief description of the target coach) before being asked to rate their expectancies of the coach's competency. Gender and reputation (i.e., successful vs. unsuccessful) of the target coach were manipulated. Multivariate and follow-up univariate analyses of variance revealed that successful coaches were rated as significantly more competent than unsuccessful coaches, while the female target coach was rated as significantly less competent than the male target coach on some competency dimensions. Athletes also reported that reputation influenced their expectancies more than gender. These findings indicate that athletes' expectancies of coaching competency are influenced by the coach's reputation and gender, although this impact appears to be more pronounced for reputation. Such results have implications for the development of effective coach-athlete relationships.
