Data were collected from July 2019 to July 2020. - Setting The app is enabling users to access video-based educational content via their smartphone. A clinical visit or in-person contact was not required. Participants All individuals registered in the freely available app were invited to take part in the study. - Interventions The app aims to increase physical activity in everyday life. It combines educative videos on lifestyle-related benefits and instructional videos of strength and endurance exercises to do at home with motivational components like goal setting, documentation of progress and personalised messages. - Primary and secondary outcome measures Primary outcomes were physical activity based one MET minutes per week (metabolic equivalent) and step numbers. Secondary outcomes included physical self-efficacy (motivational, maintenance, recovery self-efficacy), health-related quality of life: Mental Health Component Summary score and Physical Health Component Summary score. - Results Of 97 people included in the data analysis, 55 successfully completed the programme and all questionnaires. Significant increases over eight programme weeks (between T0 and T2) were observed in physical activity based on MET minutes per week, health-related quality of life, and recovery self-efficacy. Time spent sitting and body mass index significantly decreased for those completing the programme. Conclusions Although significant benefits of physical activity were observed following a complete-case analysis, results should be dealt with caution. Studies with a larger and less heterogeneous sample and robust study designs able to measure causal effects would be desirable.

Die literatuurondersoek het getoon dat doelorientering oar twee komponente beskik, naamlik taakbetrokkenheid en egobetrokkenheid. Taakbetrokke sportdeelnemers fokus op vaardigheidsontwikkeling en gebruik hulle eie prestasies as maatstaf vir sukses.

Egobetrokkenheid hou negatief verband met die fisieke self, en positief verband met kompetisie-angs. / The research investigated, in the literature and empirically, the possible relation between the goal orientation of male adolescent rugby players and their self-concept. The literature study indicated that goal orientation has two components, namely task involvement and ego involvement. In task-involved sport participation, skills development is emphasized, evaluation of achievement is self-referenced, and success experienced when learning takes place, a task is mastered, or when there is improvement in the execution of tasks. Success is attributed to effort. In ego-involved sport participation objective outcomes are emphasized (i.e. winning), evaluation of achievement is norm-based, and success experienced when own achievements are favourably compared to those of other sport participants. Success is attributed to natural ability. The empirical study indicated a positive relation between task-involved sport participation and the global, personal, and social self. A negative relation between ego-involved sport participation and the physical self, and a positive relation between ego involvement and competition-anxiety was found. / Educational Studies / M.Ed.

44	L'actitud crítica sobre el culte al cos des de l'educació física. Investigació-acció entorn del disseny, aplicació i avaluació d'un recurs educatiu multimèdia Tirado Ramos, Miguel Ángel 12 July 2010 (has links) Aquest context de cultura del consum en què ens trobem, on la mercadotècnia ha aconseguit associar un determinat model corporal a l'èxit personal i social -relació que s'intensifica en l'adolescència, quan l'aspecte físic és objecte de la màxima atenció i preocupació- ha motivat la realització d'una intervenció específica des de l'educació física a través d'un procés d'investigació-acció.L'objectiu de la recerca ha consistit en desenvolupar l'actitud crítica de l'alumnat cap al culte exacerbat al cos mitjançant el disseny, aplicació i avaluació d'un recurs educatiu multimèdia. Tot això en el marc d'una unitat didàctica de condició física i salut per a 4t d'ESO.En la investigació s'analitzen els fonaments curriculars i pedagògics d'aquesta intenció educativa i es delimita conceptualment el principal objecte d'ensenyança: l'actitud crítica. Posteriorment es dissenya, es descriu i s'avalua un pla d'acció aplicat de manera sistemàtica i amb el rigor científic que requereix una recerca que naix i es desenvolupa en la pràctica. / El contexto de cultura del consumo en que nos encontramos, donde la mercadotecnia ha conseguido asociar un determinado modelo corporal al éxito personal y social -relación que se intensifica en la adolescencia, cuando el aspecto físico es objeto de la máxima atención y preocupación- ha motivado la realización de una intervención específica desde la Educación Física a través de un proceso de investigación-acción.El objetivo de la investigación ha consistido en desarrollar la actitud crítica del alumnado hacia el culto al cuerpo exacerbado mediante el diseño, aplicación y evaluación de un recurso educativo multimedia. Todo ello en el marco de una unidad didáctica de condición física y salud para 4º de ESO.En la investigación se analizan los fundamentos curriculares y pedagógicos de esta intención educativa y se delimita conceptualmente el principal objeto de enseñanza: la actitud crítica. Posteriormente se diseña, se describe y se evalúa un plan de acción aplicado de manera sistemática y con el rigor científico que requiere una investigación que nace y se desarrolla en la práctica. / The consumer society in which we live, together with certain merchandising campaigns, has resulted in the fact that people tend to associate more and more the idea of a "perfect body" with personal and social success. Needless to say, people are more and more concerned about their physical appearance during adolescence. All this has inspired a thorough study on this topic from the perspective of the physical education and by means of an "Action-Research" process.The aim of this research was that some students in the fourth year of ESO (the last compulsory school year in the Spanish educational system) should acquire a critical attitude towards the body-building and body-care obsession. This study has been carried out by designing and using an Educational Multimedia Resource.This educational research is to be justified in the curricular foundations of the Spanish educational system and it aims to define clearly the core of this study: the development of a critical attitude. Several teaching strategies are designed, described and assessed, so that students can develop this critical thinking.All in all, the final goal is that students are able to develop a critical attitude while working from their own experiences. way of living adverts body consumption curriculum key skills critical pedagogy physical appearance physical self-description health physical condition educational multimedia resource educational strategy critical thinking adolescence critical attitude body-building physical education Action-research estilo de vida publicidad consumo corporal currículum competencias básicas pedagogía crítica imagen corporal autoconcepto físico salud condición física Recurso Educativo Multimedia (REM) intervención didáctica pensamiento crítico adolescencia actitud crítica culto al cuerpo Educación Física Investigación-acción estil de vida publicitat consum corporal currículum competències bàsiques pedagogia crítica imatge corporal autoconcepte físic salut condició física intervenció didàctica Recurs Educatiu Multimèdia (REM) pensament crític adolescència actitud crítica Investigació-acció Educació Física culte al cos Didàctica i Organització Escolar 37
