Memo is a structure of the Educational Services Sector of the Municipality of Modena, recognized as a Service and Consultancy Center for the educational infancy institutions of Emilia Romagna Region (DGR n.262/2010 as amended by DGR n.2185/2010). This educational multicenter is also accredited by the Ministry of Education (MIUR) for the training of school staff, refers to the Ministerial Directive n.170/2016. This article has analyzed seventy-tree educational projects through the narrative synthesis approach, derived from the qualitative analysis of the focus group reports (Oprandi, 2001; Cataldi, 2009), and based on the following steps: a) determination of the aim extrapolation of general didactic guidelines useful to outline applicable good practices for an educational project in outdoor education; b) identification of the relevant parts of the projects analyzed with respect to the purpose of the research; c) classification of categories referring to the relevant parts of the text; d) identification of the characteristic elements of the individual categories; e) summary of good educational practices. The teachers have shown that they know how to get involved and measure themselves with the daily work tools that they have highlighted in four main elements: a) teaching approach, b) methodology, c) characteristics of the setting, d) partnership. These four elements, deduced from the project’s analysis, underline an educational approach centered on the child and on his needs. Active and open didactics, spaces prepared in structured and unstructured forms, various materials, are always organized and combined by the adult to give space to the spontaneous action of the child. In this sense, outdoor education represents a winning strategy for teachers, thanks to its great operational adaptability of teaching. Each teacher, observing their children, can carry out educational projects appropriate to his/her school, to the spaces and times available, being able to give children great operational freedom without losing sight of the educational objectives of the school.","PeriodicalId":38917,"journal":{"name":"Journal of Physical Education and Sport","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71218482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose: The purpose of this study was to profile the physiological characteristics of amateur boxers using a battery of tests designed to assess the physiological and physical demands required for performance. Fifteen junior amateur (age 14.9 ± 2.0 years; stature 164 ± 12 cm; body mass 50.9 ± 11.3 kg) and sixteen senior amateur boxers (n = 16; age 20.5 ± 4.0 years; stature 174 ± 9 cm; body mass 65.2 ± 10.7 kg) provided informed consent to participate in the study. Body composition, squat jump (SJ), countermovement jump (CMJ), 5-and 10 m sprint (5SP/10SP), press up (PU), right and left medicine-ball single-arm throws (MBR, MBL), repeated sprint test (RST) and Yo-Yo intermittent recovery test level 1 (YY) were performed. The likelihood (% chance) of between-group differences were assessed using a magnitude based approach, standardised-difference score (Cohen’s d) and 90% confidence intervals [CI]. Linear regression (r) was used to examine the association between variables. Results: Senior boxers outperformed (79 to 99% chance) junior counterparts in PU, YY, CMJ, SJ, 10SP, MBL and MBR tests (d ≥ 0.50 [-0.34 to 1.61]). There were very large (r 0.70) correlations between fat free mass, upper-and lower body lean mass and medicine ball throw distance. There were large correlations (r 0.50 to 0.69) between medicine ball throw distance and CMJ, SJ, PU, 5SP and 10SP.

Method: Seven Paralympic and five Olympic male Brazilian swimmers took part in this qualitative study.

Cognitive therapy theory wasused to establish some of the themes and sub-themes, also to contribute to the data analysis.Results: Functional cognitions and pleasant emotions were more commonly reported by swimmers associated to their best performances, whilst dysfunctional cognitions and unpleasant emotions were more common in their worst performances, both influenced by their beliefs about the preparation during the season.Swimmers used imagery, breathing, music, self-talk, and cognitive restructuring to manage their cognitions and emotions, mainly in the day of their best performances. Although swimmers believed that cognitions and emotions could influence their performances, they reporteddifficulty identifying, evaluating, and modifyingtheir dysfunctional thinking.

Thus, the purpose of the present study was to expand previous knowledge and examine the acute effects on the EF – working memory and inhibition – in two primary level class cohorts (4th class: n = 20 students, mean age 9.95 ± .39 years; 6th class: n = 23 students, mean age 12.00 ± .30 years; 22 boys, 21 girls) of a school-based PA policy in a four-week design intervention programme. Methods: The PA policy included Physical Education (PE), Structured Play (SP) and Unstructured Play (UP). Testing of EF was carried out with a Working Memory Test and an Animal Stroop Test, before and after each session of each PA policy component. To determine whether each component of the PA intervention had an effect on working memory and inhibition, two separate repeated measures multivariate analysis of variance, controlling for gender and class as between-subject factors. Results: Results showed that the PE intervention improved more students’ working memory (3.49% increase), comparing to SP (p = .002, η = .057) and UP (p < .001, η = .077) interventions. Furthermore, the PE intervention improved more students’ inhibition (3.57% increase), comparing to SP (p = .001, η = .074) and UP (p < .001, η = .105) interventions. No gender and class differences were observed. Discussion: While whole school PA policies need to focus on all PA components and provide schoolbased opportunities to meet PA recommendations to benefit health in general, PE appears to be more beneficial for improving most students’ EF. Based on this finding, it is suggested that structured PE to be prioritised when developing PA policy in schools. Potential causes on the differences direct the conclusion towards school-based PA policy recommendations.","PeriodicalId":38917,"journal":{"name":"Journal of Physical Education and Sport","volume":"20 1","pages":"3260-3266"},"PeriodicalIF":0.0,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48292693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
