School-based prevention: effects on obesity and physical performance after 4 years

Juvenile obesity is increasing worldwide. Preventive strategies are warranted. The school-based Children's Health Interventional Trial (the CHILT Project) combines health education and physical activity for children. The effect on obesity and physical performance was studied after four years in 12 primary schools compared with five control schools. Anthropometric data were recorded. Physical performance was measured by a coordination test for children (balancing backwards, one-legged obstacle jumping, lateral jumping, sideways movements) and a 6-min run (endurance). No difference in the prevalence and incidence of overweight and obesity was found between the intervention and control schools before and after the intervention. Remission of overweight was higher in the intervention schools (23.2 vs. 19.2%), but not significant. An increase in coordination related to lateral jumping and balancing backwards was apparent in the intervention schools (30.6, s = 10.8 vs. 26.1, s = 10.8, P = 0.005; 21.8, s = 11.8 vs. 19.4, s = 11.7, P = 0.007), and the increase in endurance performance tended to be higher in intervention schools (100.8, s = 122.7 vs. 92.8, s = 126.0, P = 0.055), adjusted for age, sex, baseline test result, and body mass index at final examination. Therefore, preventive intervention in primary school offers the possibility to improve physical performance in children. The prevalence and incidence of obesity were not affected.  相似文献   

Cycling power output produced during flat and mountain stages in the Giro d'Italia: a case study

Until recently, the physiological demands of cycling competitions were mostly reflected by the measurement of heart rate and the indirect estimation of exercise intensity. The purpose of this case study was to illustrate the varying power output of a professional cyclist during flat and mountain stages of a Grand Tour (Giro d'Italia). Nine stage recordings of a cyclist of the 2005 Giro d'Italia were monitored using a mobile power measurement device (SRM Trainingssystem, Julich, Germany), which recorded direct power output and heart rate. Stages were categorized into flat (n = 5) and mountain stages (n = 4). Data were processed electronically, and the overall mean power in flat and mountain stages and maximal mean power for various durations were calculated. Mean power output was 132 W +/- 26 (2.0 W x kg(-1) +/- 0.4) for the flat and 235 W +/- 10 (3.5 W x kg(-1) +/- 0.1) for the mountain stages. Mountain stages showed higher maximal mean power (367 W) for longer durations (1800 s) than flat stages (239 W). Flat stages are characterized by a large variability of power output with short bursts of high power and long periods with reduced intensity of exercise, whereas mountain stages mostly require submaximal, constant power output over longer periods.  相似文献

Infant-directed speech does not always involve exaggerated vowel distinctions: Evidence from Danish     

Christopher Cox  Christina Dideriksen  Tamar Keren-Portnoy  Andreas Roepstorff  Morten H. Christiansen  Riccardo Fusaroli 《Child development》2023,94(6):1672-1696

This study compared the acoustic properties of 26 (100% female, 100% monolingual) Danish caregivers' spontaneous speech addressed to their 11- to 24-month-old infants (infant-directed speech, IDS) and an adult experimenter (adult-directed speech, ADS). The data were collected between 2016 and 2018 in Aarhus, Denmark. Prosodic properties of Danish IDS conformed to cross-linguistic patterns, with a higher pitch, greater pitch variability, and slower articulation rate than ADS. However, an acoustic analysis of vocalic properties revealed that Danish IDS had a reduced or similar vowel space, higher within-vowel variability, raised formants, and lower degree of vowel discriminability compared to ADS. None of the measures, except articulation rate, showed age-related differences. These results push for future research to conduct theory-driven comparisons across languages with distinct phonological systems.  相似文献   

Creating effective teaching and learning environments: Building a positive behavioural support (PBS) model for UK special schools     

Louise D. Denne  Corinna F. Grindle  Suzi J. Sapiets  Millie Blandford-Elliott  Richard P. Hastings  Marguerite Hoerger  Katy Lambert-Lee  Andreas Paris  Gemma Nicholls  J. Carl Hughes 《Support for Learning》2023,38(4):183-193

The importance of reducing restraint and restrictive interventions in special schools has been recognised across the four nations of the UK. Government guidance for England and Wales, and recommendations produced by Restraint Reduction Scotland, both reference Positive behavioural support (PBS) as an evidence-based approach that can be used to proactively support pupils with, or at risk of, behaviours that challenge. The Department of Education of Northern Ireland recommends the development of behaviour support plans to support children with special education needs and disabilities. Special schools, however, also have a responsibility to set high expectations for every pupil, to provide access to the respective national curricula and to meet individual needs. School-wide positive behavioural support (SW-PBS), originated in the USA in the 1990s in response to a body of evidence that showed improved social and academic outcomes when behavioural interventions were implemented across whole school settings. It is increasingly being adopted in the UK. Drawing upon examples from schools in England and Wales with which the authors are familiar, this paper outlines the rationale for a special schools' model of SW-PBS and illustrates the ways in which this can be adjusted to meet the specific needs of each setting.

Key Points

• Reducing restraint and restrictive interventions in schools is a high priority across all four nations of the UK.
• Special schools also have a responsibility to provide children with special education needs and disabilities positive learning environments that maximise learning opportunities and meet individual needs.
• School-wide positive behaviour support (SW-PBS) provides a useful framework to help special schools meet these expectations.
