Building upon Deci's and Ryan (1985) Self-determination theory as well as the sportive behavioral correlates of the model of Commitment (Scanlan et al., 1976), this study tries to establish the relationship between motivation and commitment in youth sport. For this purpose 454 young competitive soccer players answered the Sport Motivation Scale (SMS) and the Sport Commitment Questionnaire (SCQ) during the regular season. The SMS measures the three dimensions of the Motivational continuum (the Amotivation, the Extrinsic Motivation and the Intrinsic Motivation). The SCQ measures the Sportive Commitment and its composing factors such as the Enjoyment, the Alternatives to the sport, and the Social Pressure. Our findings provided a clear pattern of the influence of motivation in sport enjoyment and commitment, outlining the positive contribution of intrinsic and extrinsic motivation to enjoyment and commitment. Amotivation, contributes positively to alternatives to sport and negatively to enjoyment and commitment. It should be noted that extrinsic motivation has a higher contribution to enjoyment whereas intrinsic motivation has a higher contribution to commitment.Fundamentándose en la teoría de la Autodeterminación (Deci y Ryan, 1985) así como en los correlatos conductuales del modelo de Compromiso (Scanlan et al. 1976), este estudio trata de establecer las relaciones entre motivación y compromiso en jóvenes jugadores de fútbol. Con este propósito 454 jóvenes jugadores de fútbol contestaron la Escala de Motivación Deportiva (SMS) y el Cuestionario de Compromiso Deportivo (SCQ).El SMS mide las tres dimensiones del continuum motivacional (Amotivación, Motivación extrínseca y motivación intrínseca). El SCQ mide el compromiso deportivo y los factores que lo componen, tales como el disfrute, las alternativas al deporte y la presión social. Nuestros resultados proporcionan un patrón claro acerca de la influencia de la motivación en el compromiso y la diversión en el deporte, subrayando la contribución positiva de la motivación intrínseca y extrínseca en la diversión y el compromiso. La amotivación contribuye positivamente a las alternativas al deporte y negativamente a la diversión y el compromiso. Es de destacar que la motivación extrínseca tiene una contribución mayor a la diversión, mientras que la motivación intrínseca tiene una contribución mayor al compromiso.

The present study findings confirm that children are able to learn healthy backpack habits which might prevent future low back pain.

A group-randomized controlled trial was carried out to investigate the effects of a postural education program on daily life habits related to low back pain in children. The study sample included 137 children aged 10.7 years. 6 classes from 2 primary schools were randomly allocated into an experimental group (EG) (N=63) or a control group (CG) (N=74). The EG received a postural education program over 6 weeks consisting of 6 sessions, while the CG followed the usual school curriculum. A questionnaire was completed by the participants at pretest, post-test and 3 months after the intervention finished. The outcomes collected were: correct use of sofa, stooping correctly, take care to sit correctly at home/school and frequent posture change on chair at home/school. A sum score was computed from the 6 items. To examine the effect of the intervention, we used repeated measures analysis of co-variance (ANCOVA); with baseline, post-test and follow-up outcome values as dependent variables, study group as fixed factor, and sex and age as covariates. Single healthy items mostly improved after the intervention and remained improved after 3 month follow-up in EG, while no substantial changes were observed in the CG. Healthy habits score was significantly increased at post-test compared to baseline in the EG (P<0.001), and remained significantly increased after 3-months, compared to baseline (P<0.001). No significant changes were observed in the CG (P>0.6). The results suggest that children are able to learn healthy daily life habits which might contribute to future prevention of low back pain.

Borras PA, Vidal J, Ponseti X, Cantallops J, Palou P. Predictors of quality of life in children. J. Hum. Sport Exerc. Vol. 6, No. 4, pp. 649-656, 2011. The aim of this study was to explore the relationship between Health related quality of life (HRQoL) in children reported by parents, cardiorespiratory fitness, physical activity levels, screen time and body mass index of a population of 302 eleven and twelve years old children. The objective was to investigate the relation of cardiorespiratory fitness with some domains of quality of life to determine if fitness is a key factor rather than physical activity, to ensure future quality of life in children, Child health and Illness Profile-Child Edition/Parent Repot Form (CHIP-CE/PRF) was used to measure HRQoL, 20m shuttle run test, for fitness. SHAPES, Physical activity module was used to measure weekly physical activity and screen time. Height and weight was reported by parents. Results show a strong correlation with Fitness and HRQoL, and screen time with HRQoL, but not with Physical activity. The findings of this study suggest that Fitness in children is a more important predictor, than PA in disease prevention.
