随着我国体育事业的快速发展，运动员膳食营养保障越来越备受关注。合理膳食营养补给是运动员日常营养所需和提高运动能力的重要物质基础。但由于运动营养管理人力资源不足、营养宣教不够深入全面，营养认知仍较薄弱等原因，运动员实际用餐过程中仍然存在较明显的营养误区。所以，改善运动员用餐现状、提高运动员营养素养是保障运动员合理营养的重要工作内容。 相似文献

竞技体育由于其自身的特点,对运动员的膳食营养有着特殊的要求。合理、均衡的营养对与运动员的体能状况、健康水平、都有着积极的促进作用,而且在一定程度上决定着运动员的运动成绩和运动能力。为了解沈阳体育学院竞技体校优秀运动员的维生素摄入情况,采用称重法对沈阳体育学院竞技体校优秀运动员进行为期五天的膳食调查。研究发现,沈阳体育学院竞技体校优秀运动员的维生素摄入情况如下：维生素A：1144．97mglKE,维生素E：39．26mg,维生素B1：2．1mg,维生素B2：1．52mg,维生素c：85．98mg,烟酸：19．04mg。其中只有维生素E的摄入量达到了运动员合理营养推荐量,烟酸的摄入量呈边缘性缺乏状态．其余的均没有达到相应的推荐量。 相似文献

We examined whether perceived competence moderated the relationships between implicit theories, 2 x 2 achievement goals, and intrinsic motivation for sports and physical activity. We placed 309 university students into high and moderate perceived competence groups. When perceived competence was high, entity beliefs did not predict the performance-avoidance goal; yet when perceived competence was moderately low, entity beliefs did predict this goal. The mastery-avoidance goal had no relationship with intrinsic motivation when perceived competence was high, but had a significant negative relationship when perceived competence was moderately low. Our findings highlight the importance of reexamining the role of perceived competence when studying implicit beliefs and the 2 x 2 achievement goals. 相似文献

Abstract This study examined the interrelationships among perceived physical competence, motor competence, and participation in organized sport in young children. Males and females in Grades K through 4 (n = 250) were given The Perceived Competence Scale for Children (Harter, 1979) or The Pictoral Scale for Perceived Competence and Social Acceptance for Young Children (Harter, Pike, Efron, Chao, & Bierer, 1983), a 9-item motor competence assessment battery, and a questionnaire regarding their participation in sport. Results revealed that perceived physical competence for children in these grade levels was not significantly related to their participation in organized sport programs. Motor competence was significantly related to participation in that participants in organized sport programs performed selected gross motor tasks better than did nonparticipants. Further, children's reported perceptions of physical competence were significantly related to their demonstrated motor competence. Discussion focused on the theoretical and practical implications of the results. 相似文献

Abstract The associations between physical competence, self-perceived bodily competence, parental concern for their children's motor skill development, and teachers' evaluation of their bodily competence were assessed in 646 six- to seven-year-olds. Physical competence was assessed by the German motor ability test “Körperkoordinationstest für Kinder”, while the children's, their parents', and their teachers' evaluations were obtained through questionnaires. Parental concern, teacher evaluation, and a high body mass index were the strongest predictors of low physical competence (motor skill quotient <85). Teachers' evaluation of bodily competence was associated with low self-perceived bodily competence in the children even after adjustment for motor skill quotient, with an odds ratio of 2.3 (P < 0.05) between the lowest and highest of the three levels after correction for motor skill competence. Results indicate that teachers' evaluation of children's motor skills should be considered a key factor when tracking and assessing physical competencies among youth. 相似文献

Based on self-determination theory (Deci & Ryan, 2000), an experimental study with middle school students participating in a physical education task and a correlational study with highly talented sport students investigated the motivating role of positive competence feedback on participants' well-being, performance, and intention to participate. In Study 1, structural equation modeling favored the hypothesized motivational model, in which, after controlling for pretask perceived competence and competence valuation, feedback positively predicted competence satisfaction, which in turn predicted higher levels of vitality and greater intentions to participate, through the mediation of autonomous motivation. No effects on performance were found. Study 2 further showed that autonomous motivation mediated the relation between competence satisfaction and well-being, whereas a motivation mediated the negative relation between competence satisfaction and ill-being and rated performance. The discussion focuses on the motivational role of competence feedback in sports and physical education settings. 相似文献
