A comparison of anthropometric and training characteristics of Ironman triathletes and Triple Iron ultra-triathletes     

Knechtle B  Knechtle P  Rüst CA  Rosemann T 《Journal of sports sciences》2011,29(13):1373-1380

We examined differences in anthropometry and training between 64 Triple Iron ultra-triathletes competing over 11.4 km swimming, 540 km cycling, and 126.6 km running, and 71 Ironman triathletes competing over 3.8 km swimming, 180 km cycling, and 42.2 km running. The association of anthropometry and training with race time was investigated using multiple linear regression analysis. The Triple Iron ultra-triathletes were smaller (P < 0.05), had shorter limbs (P < 0.05), a higher body mass index (P < 0.05), and larger limb circumferences (P < 0.01) than the Ironman triathletes. The Triple Iron ultra-triathletes trained for more hours (P < 0.01) and covered more kilometres (P < 0.01), but speed in running during training was slower compared with the Ironman triathletes (P < 0.01). For Triple Iron ultra-triathletes, percent body fat (P = 0.022), training volume per week (P < 0.0001), and weekly kilometres in both cycling (P < 0.0001) and running (P < 0.0001) were related to race time. For Ironman triathletes, percent body fat (P < 0.0001), circumference of upper arm (P = 0.006), and speed in cycling training (P = 0.012) were associated with total race time. We conclude that both Triple Iron ultra-triathletes and Ironman triathletes appeared to profit from low body fat. Triple Iron ultra-triathletes relied more on training volume in cycling and running, whereas speed in cycling training was related to race time in Ironman triathletes.  相似文献   

The role of athlete narcissism in moderating the relationship between coaches' transformational leader behaviors and athlete motivation     

Arthur CA  Woodman T  Ong CW  Hardy L  Ntoumanis N 《运动与训练心理学杂志》2011,33(1):3-19

Leadership research that examines follower characteristics as a potential moderator of leadership effectiveness is lacking. Within Bass's (1985) transformational leadership framework, we examined follower narcissism as a moderator of the coach behavior-coach effectiveness relationship. Youth athletes (male = 103, female = 106) from the Singapore Sports Academy (mean age = 14.28, SD = 1.40 years) completed the Differentiated Transformational Leadership Inventory (Callow, Smith, Hardy, Arthur, & Hardy, 2009), the Narcissistic Personality Inventory (Raskin & Terry, 1988), and indices of follower effort. Multilevel analyses revealed that athlete narcissism moderated the relationship between fostering acceptance of group goals and athlete effort and between high performance expectations and athlete effort. All the other transformational leader behaviors demonstrated main effects on follower effort, except for inspirational motivation.  相似文献

Gallery One at the Cleveland Museum of Art     

Jane Alexander 《Curator: The Museum Journal》2014,57(3):347-362

How can art museums use interpretive technology to engage visitors actively in new kinds of experiences with works of art? What are the best strategies for integrating technology into the visitor experience? In 2012, the Cleveland Museum of Art responded with Gallery One, an interactive art gallery that opened to stakeholders on December 12, and went through a six‐week testing period before its public opening on January 21, 2013. Gallery One drew from extensive audience research and was part of a major building and renovation project in which CMA reinstalled and reinterpreted the entire permanent collection in new and renovated gallery spaces. The end result was an innovative and robust blend of art, technology, design, and a unique user experience that emerged through the collaboration of staff across the museum and with outside consultants.  相似文献   

Libraries,Mobile Devices,and the Visible College     

Bryan Alexander  Paula Sullenger 《期刊图书馆员》2014,66(1-4):31-43

Bryan Alexander described the digital environment that we live in, giving an extensive overview of the current state of interactive devices, particularly mobile devices, which are moving us beyond the personal computer. He covered recent major developments that have transformed the world in surprising ways in a rather short period of time. The world of apps is further expanding what these devices can do, also bringing with them more challenges to individual privacy. Gaming and augmented reality are becoming deeply embedded in much of what we do. Alexander laid out four possible futures that these contemporary developments could lead to.  相似文献   

The Benefits of Peer Collaboration: A Replication with a Delayed Posttest     

Victoria Manion Fleming  Joyce M. Alexander 《Contemporary educational psychology》2001,26(4):588

The benefits of peer collaboration on strategy use, metacognitive causal attribution, and recall were supported in an earlier study (Manion & Alexander, 1997). Following that study two primary questions remained: Would the observed benefits last beyond an immediate posttest, and would they last regardless of which strategy the children chose to use? The current investigation explores those questions. Thirty-one fourth-grade students from two public schools in Sydney, Australia, experienced either a peer-collaborative treatment condition or an individual task (control condition). A posttest was conducted 5.5 weeks later. As was the case in the original study, children in the treatment condition outperformed children in the control condition in strategy use, metacognitive understanding of strategy chosen, and recall gain. Benefits also sustained regardless of the strategy children chose to implement on the task. Most importantly, the benefits lasted after a period of over a month. Implications for future research are discussed.  相似文献
