"Physical, sport and life skills education: Promoting the individual person, and not only the athlete through Life Skills and multi-sports training in Physical Education." Author Rosalba Marchetti Abstract Given the social importance of the relevance of the development and life of children and adolescents, a multi-faced study of movement components is essential to design relevant aspects of quality Physical Activity contributing to the promotion of children's and adolescent's development. First cross-sectional study: the situational differences created by significant others in family and sport settings, such as parents and coaches, are reflected in the motivational climate perceived by youths; these affect their individual characteristics, such as achievement goals, self-determination, self-efficacy in life skills, and adaptive/maladaptive behaviours. There still is scarce evidence on the potential associations between mastery versus performance oriented climate generated by coaches and parents, and youths’ self-perceptions in life skills, which are considered protecting factors against maladaptive behaviours (WHO, 2003). This study examines if the motivational climate created by significant others (coaches and parents) and the individual motivational orientation in sports are associated with youths’ self-awareness in intra-and interpersonal life skills. Results highlight the role played by both individual goal orientations in sport and the motivational climate generated by significant others in the development of youths’ life skills. Then suggest that task orientation and a mastery, learning and enjoyment climate may contribute to their development, while ego and performance orientation, a climate oriented to worry conducive and reinforces success without effort may be detrimental. Second cross-sectional study: recent evidence suggests that fitness and sport expertise may jointly benefit cognition (Chan, Wong, Liu, Yu, & Yan, 2011) and expertise in cognitively demanding strategic sports is linked to performance advantages not only in domain-specific cognition (Williams & Ericcson, 2005), but also in domain-general cognitive function, the executive (Vestberg et al., 2012). However, there still is a paucity of research focusing on whether physical fitness, motor and sport skill proficiency are independent determinants of executive function efficiency, or interact within each other determining a more complex pattern of moderated prediction. This crosssectional study is aimed at investigating this issue in preadolescents and adolescents. The present findings support the hypothesis that there may be different pathways through which PA and sport practice influence executive functions: the well-known linkage between physical fitness and executive functions. Other putative pathways seem to be those linking executive function to the ability to perform coordinated movements in response to environmental cues and to the ability to perform cognitively challenging, strategic game actions. Also, the findings highlight that different executive function are differently linked to physical fitness and motor and sport proficiency. First intervention study: the effectiveness of life skills programmes in Physical Education (PE) and youths sport for promoting skill development in motor and non-motor domains has been proved by a number of evaluation studies (Goudas, 2010). Thus (PE) and sport education may be regarded as a very appropriate field for introducing life skills training. Evidence consistently showed enhanced knowledge and improved confidence in applying life skills which was paralleled by gain in physical fitness and motor/sport skills. However, the potential role of life skills development as a mechanism mediating the effects of a life skills training program on motor and sport skills has not been investigated yet. Thus, the aim of the present study was to verify (1) the outcomes of a life skill programme in PE on physical fitness, cognitive efficiency, motor and sport skills and (2) whether such outcomes are mediated by gains in life skills and cognitive life skill components operationalized not only as self-evaluation, but also behavioural application in sport game situations. As compared to traditional PE without life skill training, a life skill programme integrated in a multi-sport PE setting seem to have a wide range of positive outcomes in motor and non-motor domains which are relevant to personal development. The study highlighted the usefulness of behavioural measures of life skills to identify pathways through which a life skill programme positively impacts sport game skill development. Second intervention study: in the last decades, school age youth have demonstrated declines in measures of aerobic fitness and muscle strength and in fundamental motor skills. To counteract these trends, not only an adequate amount of physical activity (PA), but also a qualitative variety of PA tasks should be ensured. While there is a claim for and evidence in favour of varied multi-sports approaches to PA for pre-adolescent children, the adolescent age is mostly considered a sport specialization age. The aim of the present study was to verify whether (1) a multi-sports PE programme benefits adolescents’ physical fitness, cognitive efficiency, motor and sport skills over a two-year intervention time and (2) whether the motor and sport skills outcomes are mediated by gains in physical fitness or cognitive efficiency. As compared to traditional PE without a special focus on multi-sport, a PE programme centred on multi-sport diversification extended over two years seems to have selective beneficial outcomes on sport skill proficiency and cognitive efficiency. Also, it seems to help females compensate the lower proficiency in stereotypically masculine sport skills as dribbling. A relevant improvement was found also in cases involving disabled students who worked in integrated groups. These students highly benefited from this equal opportunity situation and developed their motor, sport and cognitive profile. These findings highlight the importance of quality PA until adolescence and the specific role of multi-sport, skill-based curricula centred on variability of practice to obtain positive outcomes in motor and non-motor domains that may facilitate adolescent physical and mental health development and create equal opportunities of motor skill development across genders and across persons with disabilities.
