Music in the exercise domain: a review and synthesis (Part I) 总被引：1，自引：0，他引：1
Since a 1997 review by Karageorghis and Terry, which highlighted the state of knowledge and methodological weaknesses, the number of studies investigating musical reactivity in relation to exercise has swelled considerably. In this two-part review paper, the development of conceptual approaches and mechanisms underlying the effects of music are explicated (Part I), followed by a critical review and synthesis of empirical work (spread over Parts I and II). Pre-task music has been shown to optimise arousal, facilitate task-relevant imagery and improve performance in simple motoric tasks. During repetitive, endurance-type activities, self-selected, motivational and stimulative music has been shown to enhance affect, reduce ratings of perceived exertion, improve energy efficiency and lead to increased work output. There is evidence to suggest that carefully selected music can promote ergogenic and psychological benefits during high-intensity exercise, although it appears to be ineffective in reducing perceptions of exertion beyond the anaerobic threshold. The effects of music appear to be at their most potent when it is used to accompany self-paced exercise or in externally valid conditions. When selected according to its motivational qualities, the positive impact of music on both psychological state and performance is magnified. Guidelines are provided for future research and exercise practitioners. 相似文献

The use of music during exercise has become ubiquitous over the past two decades and is now supported by a burgeoning body of research detailing its effects and the contingencies surrounding its use. The purpose of this statement is to present a synopsis of the body of knowledge, with selected references, and to provide practical recommendations for exercise practitioners regarding music selection. Following the identification of methodological shortcomings in early studies, researchers have been guided by new conceptual frameworks, and have produced more consistent findings as a consequence. The use of music has been found to yield ergogenic effects in the exercise domain while also promoting psychological (e.g. enhanced affect) and psychophysical (reduced ratings of perceived exertion) benefits. There is a paucity of research examining the longitudinal effects of music on key outcome variables such as exercise adherence. 相似文献

宋诗与类书之关系 总被引：1，自引：0，他引：1

赵宋之世是我国古代文化的兴盛时期，文化事业全面发展，作为文化总结与象征的类书在宋代也进入了繁荣时期。各种类书大量涌现，而文人自行编纂、以适临文之需的类书更是层出不穷。文学大家如晏殊、秦观、黄庭坚等都有纂集之作，更遑论其他士人。在一定程度上，类书表现为宋人文化水平的平均值。这种现象一方面是文人积累学养的表现，另一方面又可使他们在濡毫之际左旋右抽，应对裕如。宋诗“以才学为诗”的特征的形成，与之有密切的联系。 相似文献

现实的企业之间普遍存在着市场扮额及利润的差距，对这种差距的解释，新古典经济学认为企业是同质的，外在市场结构因素造成了这种差距。本文认为，现实的企业是并质的，造成这种异质性的根源在于企业的核心知识和能力，同时本文还创造性地将分工、内生交易费用纳入分析框架，并相应提出了政策建议。 相似文献

In the present study, a measure to assess the motivational qualities of music in exercise was redesigned, extending previous research efforts (Karageorghis et al., 1999). The original measure, the Brunel Music Rating Inventory (BMRI), had shown limitations in its factor structure and its applicability to non-experts in music selection. Redesign of the BMRI used in-depth interviews with eight participants (mean age 31.9 years, s = 8.9 years) to establish the initial item pool, which was examined using a series of confirmatory factor analyses. A single-factor model provided a good fit across three musical selections with different motivational qualities (comparative fit index, CFI: 0.95-0.98; standardized root mean residual, SRMR: 0.03-0.05). The single-factor model also demonstrated acceptable fit across two independent samples and both sexes using one piece of music (CFI: 0.86-1.00; SRMR: 0.04-0.07). The BMRI was designed for experts in selecting music for exercise (e.g. dance aerobic instructors), whereas the BMRI-2 can be used both by exercise instructors and participants. The psychometric properties of the BMRI-2 are stronger than those of the BMRI and it is easier to use. The BMRI-2 provides a valid and internally consistent tool by which music can be selected to accompany a bout of exercise or a training session. Furthermore, the BMRI-2 enables researchers to standardize music in experimental protocols involving exercise-related tasks. 相似文献
