Purpose: The purpose of this study was to determine the influence of eight different small-sided games (SSG) on physical, technical, and decision-making demands of training environments in U14 field hockey. Methods: A total of 13 participants played eight different training games consisting of two 7.5-minute halves, where number of players (three per side or six per side) and/or field characteristics (normal game, cage hockey game, possession game, and two-goals game) was manipulated. Match performance was determined by using notational analysis, and physical demands were determined by using GPS analyses. Results: Findings revealed that lowering the number of players increased the number of technical actions performed per player and the physical demands of the SSG. Findings of the field characteristics manipulation revealed that the possession game forced players to control the ball more as a team, which resulted in more passes (+4.82 passes) and fewer dribbles (?1.48 dribbles) and tackles (?0.69 tackles) compared to the normal game. The two-goals game led to players scoring more goals (+0.61 goals) compared to the normal game, while the cage hockey game increased passing (+1.46 passes) and physical demands (+7.32 meters per minute) compared to the normal game. Conclusion: It can be concluded from these findings that coaches and trainers are able to promote a change in playing behavior, and in turn the development of skills, by manipulating specific constraints of the training environment.  相似文献

Charity sport events provide participants with a meaningful event experience, and the opportunity to support a charitable cause is a critical component of this experience. This opportunity often involves fundraising, either as a requirement of event participation or as an option to supplement registration. However, fundraising as part of charity sport event participation is a difficult task. In the current research, the authors examine the challenges faced by charity sport event participants in soliciting donations, and the effort made to overcome these challenges. Constraint negotiation served as a theoretical framework to guide this examination. Semi-structured interviews (N = 27) were conducted with Triathlon Pink participants to discuss their fundraising process and their attitudes towards fundraising. Four constraints were revealed: lack of receptivity among potential donors, perceived lack of money from potential donors, discomfort in asking, and lack of time. These constraints were negotiated through three strategies: narrative, prizes and incentives, and emphasising that any bit helps. Based upon the themes uncovered, charity sport event managers can implement increased education of fundraisers and point of sale donations within the registration process.  相似文献

Due to the proliferation of Web 2.0 technology, e-commerce has evolved into social commerce. In this social commerce era, consumers are increasingly dependent on each other and look for social support (informational and emotional) online even before making purchases. This study examines the content of consumer reviews, a fundamental construct of social commerce. Topics expressed in consumer reviews (collected from Amazon.com) are explored using a machine learning technique (i.e. latent semantic analysis). This study documents the thematic differences between positive and negative reviews and finds that negative reviews report service-related failures while positive reviews relate more to the product, among other things. Next, the informational support aspect of social commerce is explored by identifying the topics expressed in reviews that are helpful in purchase decisions. The findings demonstrate that potential customers (i.e. those who would like to purchase a product in the near future and currently are reading reviews with the intention to decide whether or not to buy that product) find the negative reviews containing service failure information and the positive reviews containing information on core functionalities, technical aspects, and aesthetics to be more helpful. Theoretical and managerial implications are discussed.  相似文献

This study explored the relationship among informational reception apprehension (IRA) factors, student motivation, and student achievement. Based on Wheeless, Preiss, and Gayle's (1997) recently developed construct, the authors hypothesized that IRA scores for listening and inflexibility would predict educational motivation scores and measures of achievement. Furthermore, this study extended existing research on student motivation and the effects of antecedent conditions, such as trait‐like IRA. Results indicated that informational reception apprehension can be taken into consideration in order to account more adequately for student motivation and achievement.  相似文献
