    The ability of body mass index (BMI) to predict excess fat in South Asian children is unknown. This cross-sectional study examines the influence of ethnicity on body fatness in children. Weight status and body fat were determined using BMI, waist circumference (WC), two skinfold sites (SF; triceps and subscapula) and leg-to-leg bioelectrical impedance analysis (BIA; Tanita BF350, Tanita, Tokyo, Japan) in 194 children aged 8.47 ± 0.50 years from Coventry, United Kingdom. Biological maturity was also determined. Analysis of covariance (ANCOVA) identified significant differences between ethnic (p 0.05). To conclude, the findings suggest that BMI cut-points may need to be lowered in South Asian children, and thus age-by-sex-by-ethnicity specific BMI cut-points are needed in children. Further research examining body composition with health parameters in this population is needed

    This study examined affordance perception for soccer dribbling using a mixed-methods approach in male grassroots soccer players. We examined how children construct and perceive skills practices for dribbling in soccer. Fourteen boys aged 10–11 years (Mean ± SD = 10.8 ± 0.4 years) who were regularly engaged in grassroots soccer participated in the present study. Children were provided with ten soccer cones and asked to create their own soccer dribbling pattern that would enable them to maximise the number of touches with a football and then dribble the ball in the pattern they had created for a 1 min period. Children were interviewed to explore their perception of affordances for soccer dribbling. The test of gross motor development-3 was used to assess fundamental movement skills (FMS), and the UGent soccer dribbling test was used to assess soccer dribbling skills. Children self-rated their own ability for soccer dribbling, as did their coaches. Pearson’s correlations were employed to examine the associations between quantitative variables, and thematic analysis was used to explore qualitative data. Results of the present study suggest that those children who created patterns with less space between cones accrued more touches of the football in their dribbling task (r = −0.671, p = 0.03). Children with a higher perception of their own dribbling ability had higher scores for FMS (r = 0.604, p = 0.049). Those children who scored better in actual soccer dribbling had higher scores for FMS (r = −0.746, p = 0.012) and were rated as better dribblers by their coaches (r = −0.67, p = 0.03). Interview data suggest a feedback loop between perception of ability and actual ability, which influenced the dribbling patterns that were created. This suggests that dribbling performance is scaled to the (perceived) action capabilities of the children, and children can act as architects in their own skill developmen

    This study assessed the effect of acute continuous and intermittent physical activity (PA) on children's executive function (EF). Twenty-four participants (14 boys M = 10.32 ± 0.48 years), using a within-subjects design, performed a continuous (70% HRmax) and an intermittent (≄85%HRmax; 12 bouts: 30 s work, 45 s rest) PA bout of cycling, both lasting 15 min. Executive function was assessed using the Stroop task, Digit Span and Corsi Blocks tests and these were administered before and 1 min and 30 min post PA. Comparing both conditions, performance at the Stroop task (i.e., reaction time) improved in the continuous condition after 1 min and after 30 min (congruent stimuli) (mean diff = 126 ms ± 59; p = 0.047 and mean diff = 89 ms ± 38; p = 0.031, respectively). The intermittent condition improved at 30 min post (congruent and incongruent) (mean diff = 116 ms ± 46; p = 0.021 and mean diff = 111 ms ± 49; p = 0.039, respectively) showing a delayed benefit from the PA bout and greater improvements compared to the continuous condition. Verbal memory was improved for the continuous condition 1 min post only and no effects on visual memory were observed for both experimental conditions. The results demonstrated that both acute PA bouts might be a time-efficient approach for enhancing EF, with intermittent PA having a delayed and greater benefit

    Calibration and Cross-Validation of Accelerometery for Estimating Movement Skills in Children Aged 8-12 Years

    This study sought to calibrate triaxial accelerometery, worn on both wrists, waist and both ankles, during children’s physical activity (PA), with particular attention to object control motor skills performed at a fast and slow cadence, and to cross-validate the accelerometer cut-points derived from the calibration using an independent dataset. Twenty boys (10.1 ±1.5 years) undertook seven, five-minute bouts of activity lying supine, standing, running (4.5kmph−1) instep passing a football (fast and slow cadence), dribbling a football (fast and slow cadence), whilst wearing five GENEActiv accelerometers on their non-dominant and dominant wrists and ankles and waist. VO2 was assessed concurrently using indirect calorimetry. ROC curve analysis was used to generate cut-points representing sedentary, light and moderate PA. The cut-points were then cross-validated using independent data from 30 children (9.4 ± 1.4 years), who had undertaken similar activities whilst wearing accelerometers and being assessed for VO2. GENEActiv monitors were able to discriminate sedentary activity to an excellent level irrespective of wear location. For moderate PA, discrimination of activity was considered good for monitors placed on the dominant wrist, waist, non-dominant and dominant ankles but fair for the non-dominant wrist. Applying the cut-points to the cross-validation sample indicated that cut-points validated in the calibration were able to successfully discriminate sedentary behaviour and moderate PA to an excellent standard and light PA to a fair standard. Cut-points derived from this calibration demonstrate an excellent ability to discriminate children’s sedentary behaviour and moderate intensity PA comprising motor skill activity.N/

    The Acute Effects of Cognitively Demanding Physical Activity on Inhibitory and Affective Responses in Children:An Online-Based Mixed Methods Approach

    Get PDF
    This online study investigated the acute effects of a cognitively demanding physical activity (CDPA) vs a simple physical activity (SPA) bout on children’s inhibitory and affective responses. Using a counterbalanced within-subjects’ crossover design, thirty-nine participants aged 9–12 years old (29 boys; M(age) = 11 ± 1 years) performed a CDPA and a SPA bout online (via ZOOM) for 15 min. Inhibition (Stroop test) was measured at the baseline, 1 and 30 min following the physical activity (PA) bouts, and self-report measures of affect, mental and physical exertion were taken prior, during and post-PA. Additionally, 31 children took part in semi-structured focus groups to explore the factors affecting their enjoyment. The quantitative results suggest no significant differences on inhibitory responses, affect and physical exertion (all p > 0.05). However, the CDPA induced more mental exertion than the SPA did (p < 0.05). In the focus groups, four themes were identified: physical exertion (e.g., tiredness), social (e.g., teams/groups), environment (e.g., outdoors and competition) and emotional (e.g., fun/enjoyment). Some children (n = 18) reported that the CDPA condition confused them, and to make these activities more interesting and enjoyable, they suggested performing the activities outdoors (n = 15) and including other children as part of a group/team (n = 19). The findings suggest no additional benefit of a cognitively enriched physical activity compared to an SPA bout on the inhibitory responses, affect and enjoyment. Using the instructions provided and given the low cost, the easy administration and the minimal amount of equipment and time involved, either of the approaches may be used in a diversity of contexts (i.e., online, schools or outdoors), and it is worth exploring the effects of these conditions on other aspects of executive function

    “Children are precious cargo; we don’t let them take any risks!”: Hearing from adults on safety and risk in children’s active play in schools: a systematic review

    Get PDF
    BACKGROUND: Understanding determinants of children’s outdoor play is important for improving low physical activity levels, and schools are a key setting for both. Safety concerns shape children’s opportunity to play actively outdoors, therefore, this qualitative evidence synthesis aimed to i) examine adult (e.g., parent, teacher, yard supervisor, principal) perspectives on safety and risk in children’s active play during recess in elementary and/or middle schools, and ii) identify how safety and risk influence playground supervision and decision making in this setting. METHODS: Six electronic databases were systematically searched in March 2021, with an updated search in June 2022. Records were screened against eligibility criteria using Covidence software, and data extraction and synthesis were performed using predesigned coding forms in Microsoft Excel and NVivo. Framework synthesis methodology was employed, guided by a conceptual framework structured on the socio-ecological model (SEM) and affordance theory. RESULTS: From 10,370 records, 25 studies were included that represented 608 adults across 89 schools from nine countries. The synthesis identified 10 constraining and four affording factors that influenced whether school staff were risk-averse or risk tolerant during recess, and, in turn, the degree to which children’s play was managed. Constraining factors stemmed from fears for children’s physical safety, and fear of blame and liability in the event of playground injury, which shaped parent, school staff and institutional responses to risk. Interrelated factors across SEM levels combined to drive risk-averse decision making and constraining supervision. Emerging evidence suggests children’s active play in schools can be promoted by fostering a risk tolerant and play friendly culture in schools through play facilitation training (e.g., risk-reframing, conflict resolution) and engaging stakeholders in the development of school policies and rules that balance benefits of play against potential risks. CONCLUSIONS: Findings show several socio-cultural factors limited the ability of school staff to genuinely promote active play. Future work should seek to foster risk tolerance in schools, challenge the cultural norms that shape parent attitudes and institutional responses to risk in children’s play, and explore novel methods for overcoming policy barriers and fear of liability in schools.

    What keeps FLAME lit? Comparing two modes of implementation of a physical education-based intervention to improve motor competence among Irish adolescents

    Get PDF
    Background: Adequate levels of motor competence (MC) have been associated with multiple health outcomes. Despite the preponderance of effective MC interventions, globally, levels of MC in children and adolescents are low. There is a gap in understanding what leads to effective implementation of MC interventions into routine practice, to benefit the wider population. Purpose: This study aims to compare implementation outcomes of two versions of Project FLAME: one group of teachers implementing Project FLAME as per the original efficacy trial (‘Original FLAME’), a second group of teachers implementing Project FLAME incorporating three additional implementation strategies (‘Modified FLAME’). Methods: A mixed method, two-group pre-and-post design, lasting six weeks during the period of September to November 2021. Three implementation evaluation outcomes were assessed: (i) PE teacher’s self-efficacy in delivering Project FLAME; (ii) Fidelity and adaptation to the project protocol; and (iii) Teachers’ and students’ responsiveness to the project. Data were collected at student and teacher levels using online survey and interviews. Nine PE teachers and their classes from eight schools consented to participate. Descriptives were reported for quantitative online survey data, and qualitative data were analysed thematically. Results: The final analytical sample included data from 9 teachers and 127 students pre- and post-study. Irrespective of implementation group, teachers with low levels of self-efficacy at the baseline improved after the six-week intervention. Teachers’ fidelity to the use of pedagogical external cues and error identification were high in both groups, with more adaptations made in the Modified FLAME group. Students’ satisfaction towards the intervention was high in both groups, with the use of pedagogical external cues reported as highly preferable. Conclusion: Findings provide evidence on the ‘non-negotiable’ features of Project FLAME that have the potential to be implemented for a longer-term in Physical Education settings (e.g. external teaching cues). The documented implementation of Project FLAME provide knowledge on what adaptations may be needed to translate an effective MC intervention into real-world practice. The study reaffirms that documenting the implementation (especially fidelity and adaptation) of MC interventions is beneficial.</p

    Run, Jump, Throw and Catch: How proficient are children attending English schools at the Fundamental Motor Skills identified as key within the school curriculum?

    This study examined proficiency levels in fundamental motor skills (FMS) in children within Key Stage 1 and 2 of the English school system. Four hundred and ninety-two children aged 6–9 Years old (245 boys, 247 girls) from school Years Two (n = 130), Three (n = 154) and Four (n = 208) participated in this study. FMS for the run, jump, throw and catch were assessed using the Test of Gross Motor Development – 2. The proportion of children who achieved mastery or near mastery of the skills was determined. For the whole sample, 18.5% (n = 91) did not achieve mastery in any of the four skills. A similar proportion (18.7%, n = 92) achieved mastery in all four of the FMS examined in this study. The proportion of children achieving mastery of all four skills was lower for Year Two children (0%) compared to children in years Three (24%) and Four (25%). More boys (25.7%) achieved mastery in all four of the FMS compared to girls (11.7%). Individual behavioural components in skill performance were also examined. The results of the present study highlight that less than one-fifth of children aged 6–9 years old have mastered the four key FMS identified by the physical education (PE) curriculum despite having the developmental potential to become fundamentally competent by six years of age. Fostering positive trajectories of FMS development presents a challenge for PE specialists given the association between FMS mastery in childhood and physical activity, weight status and health.N/
