This study aimed to analyse fatigue-induced changes in mechanical sprinting properties during a specific repeated-sprint test in elite rugby sevens athletes. Twenty elite rugby sevens players performed ten 40?m sprints on a 30?s cycle with participant’s running back and forth in a marked lane. Radar was used to assess maximal overground sprint performance over each 40?m. Macroscopic mechanical properties (maximal horizontal force (F0), maximal horizontal power (Pmax), maximal ratio of horizontal force (RFpeak), decrease in the ratio of horizontal-to-total force (DRF), total force and maximal sprinting velocity (v0)) were drawn from horizontal force velocity relationships, using a validated method applied to the speed–time data. Fatigue-induced changes were analysed comparing the first sprint to an average of 2nd-4th, 5th-7th and 8th-10th. Repeated-sprint ability (RSA) testing induced substantial changes in the maximal velocity component, with a decrease (–15%) in v0 (effect size (ES)?=?–2.46 to –4.98), and to a lower extent (–5.9%) in the maximal force component F0 (ES?=?–0.59). DRF moderately decreased (14%; ES=–0.76–1.11), and RFpeak largely decreased in the later sprints (ES?=?–0.32 to –1.27). Fatigue observed in this RSA test appeared to have a greater effect on the technical ability to produce horizontal force at high velocities, likely due to an alteration in the ability to maintain horizontally oriented force application when velocity increases rather than during the initial acceleration phase, but also the overall force production capacity. The ability to maintain forward-oriented force at high velocities is of central importance for identifying fatigue and monitoring load. 相似文献

Key points
- Early career researchers (ECRs) consider journals the central form of communication – but are concerned about pressure to publish.
- ECRs want to share but currently accept the closed publishing system because of the need to build a traditional reputation.
- ECRs know – and appear to care – little about publishers but trust them as publishing and reviewing facilitators.
- Editors are criticized for not managing peer review with better selection of reviewers.
- Megajournals are not seen as the future journal form and criticized for lack of selectivity.
- ECRs want open access/science in principle but are circumspect about their contribution to it.
- ResearchGate is a key force for change as ECRs consider it a mainstay communication and reputation platform.

A secondary analysis of 2010–2014 World Values Survey (WVS) data (N = 81,229) is performed across 56 countries to assess frequency of exposure to television news versus the Internet and mobile phone as information sources. A large majority of the comparisons (105/112; 93.75%) reveal television to be used more frequently than Internet or mobile phones (p < 1.0E-09). A content analysis of works published in 9 communication journals from 2010 to 2014 indicates a precipitous decline in the attention political communication scholars are giving to television. Meanwhile, there is substantial growth in the focus on new media. 相似文献

Outreach to special populations can be a sensitive endeavor, especially when the population, such as veterans, has a unique life experience in comparison to the general population. The use of oral histories for engagement and outreach can be a useful tool in making a connection to the veteran population because it gives them an opportunity to talk without being judged and the library a chance to listen. This case study highlights the collaboration between the library and the campus veteran center in an effort to come together and showcase veteran stories around their tattoos. 相似文献
