Caffeine and coffee are widely used among active individuals to enhance performance. The purpose of the current study was to compare the effects of acute coffee (COF) and caffeine anhydrous (CAF) intake on strength and sprint performance. Fifty-four resistance-trained males completed strength testing, consisting of one-rep max (1RM) and repetitions to fatigue (RTF) at 80% of 1RM for leg press (LP) and bench press (BP). Participants then completed five, 10-second cycle ergometer sprints separated by one minute of rest. Peak power (PP) and total work (TW) were recorded for each sprint. At least 48 hours later, participants returned and ingested a beverage containing CAF (300?mg flat dose; yielding 3–5?mg/kg bodyweight), COF (8.9?g; 303?mg caffeine), or placebo (PLA; 3.8?g non-caloric flavouring) 30 minutes before testing. LP 1RM was improved more by COF than CAF (p?=?.04), but not PLA (p?=?.99). Significant interactions were not observed for BP 1RM, BP RTF, or LP RTF (p?>?.05). There were no sprint?×?treatment interactions for PP or TW (p?>?.05). 95% confidence intervals revealed a significant improvement in sprint 1 TW for CAF, but not COF or PLA. For PLA, significant reductions were observed in sprint 4 PP, sprint 2 TW, sprint 4 TW, and average TW; significant reductions were not observed with CAF or COF. Neither COF nor CAF improved strength outcomes more than PLA, while both groups attenuated sprint power reductions to a similar degree. Coffee and caffeine anhydrous may be considered suitable pre-exercise caffeine sources for high-intensity exercise.  相似文献

In this paper we focus on the lived experiences of multidisciplinary scholars as we navigated and coalesced into a productive, interdisciplinary collaboration. We pull from our foundations in feminist methodology and provide excerpts from personal journals and reflexive group interviews to provide a behind-the-scenes account of the inner workings of a feminist research group. While sharing a common research goal, each member negotiated her personal, conceptual, and epistemological stances as we produced an effective, interdisciplinary pastiche. Throughout this process, we worked to create a non-hierarchical atmosphere, continuously and ethically questioned our methods, and incorporated reflexivity in the research processes. In addition to sharing our past experiences, we note challenges we encountered and offer practical suggestions based on the lessons we learned through this collaboration.  相似文献

Recent legislation in England has encouraged the use of disagreement resolution and mediation and emphasised the need to involve pupils in their own schooling. These policies apply in the educational system generally, but are particularly significant in the area of special educational needs (SEN). Kirstie Soar, a lecturer in the School of Psychology at the University of East London; Katie Burke, a PhD student at Salford University, Manchester; Katia Herbst, an independent researcher offering research and development services to the not-for- profit sector; and Professor Irvine Gersch, Director of the MSc educational psychology programme at the University of East London, set out to examine how pupil involvement in informal disagreement resolution has developed across 11 English regions since its introduction. The research consisted of 12 in-depth interviews with local education authority (LEA) SEN officers, mediators and parent partnership officers (PPOs) involved in informal special educational needs disagreement resolution. The aims of the study were to determine how far children were actually involved in mediation and what, if any, barriers existed which were seen to restrict such pupil involvement. A thematic analysis of interview content was conducted. Four major themes emerged, including: the distinction between direct and indirect pupil involvement; the importance of the child's view and how it is elicited; the role of other agencies; and other barriers to pupil involvement in informal disagreement resolution. Direct pupil involvement was found to be limited and variable, but indirect pupil involvement was more prevalent. In this article, the authors note a series of recommendations concerning pupil involvement in the mediation process and, in conclusion, put forward the implications of their work for future policy, practice and research.  相似文献

Despite the fluid and nonlinear nature of data analysis, specifically in qualitative research, published work in comparative education has rarely discussed the messy aspects of data analysis. This Forum addresses the complexity of the analysis stage faced by three doctoral researchers in terms of: considering data analysis when selecting data collection tools; messiness of data analysis deriving from fieldwork and data collection; integrating different data sources; practising reflexivity during data analysis; and ethical issues arising from data analysis. The Forum aims not only to offer suggestions and tips to deal with data analysis but also to encourage more open discussions on this topic within the research community.  相似文献

Even at the primary level, computational thinking (CT) can support young students to prepare for participating in futures that are immersed in data. In mathematics classrooms, there are few explanations of the ways CT can support students in formulating and solving complex problems. This paper presents an example of a primary classroom investigation (8-9 year olds) over seven lessons of the problem “How long does it take to read a book?” The aim is to illustrate ways a statistical investigation can provide context for CT and demonstrate how the two complement each other to solve problems involving mathematics. The findings highlight opportunities and challenges that students face across the elements of CT—decomposition, abstraction, pattern recognition and modelling, and generalization and algorithmic thinking, including recommendations for teaching.  相似文献

In 2016, The University of Tennessee at Chattanooga Library piloted a cyclical review process for five academic departments. The goal was to go beyond the traditional library portion of a department’s accreditation/program review and holistically assess electronic resources for these departments and provide recommendations for changes when necessary. This article describes the need for this kind of review, the process used to review Engineering and Computer Science resources, suggestions and decisions made as a result of the review, reflections on the experience, and hopes for the future.  相似文献

Online participatory platforms are introduced to boost citizen involvement in political decision-making. However, the design features of these platforms vary considerably, and these are likely to affect how prospective users evaluate the usefulness of these platforms. Previous studies explored how prevalent different design features are and how they affect the success of platforms in terms of impact, but the attitudes of prospective users remain unclear. Since these evaluations affect the prospects for launching successful participatory platforms, it is imperative to assess what citizens want from such digital possibilities for participation. This study uses a conjoint experiment (n = 1048) conducted in Finland that explore the impact of seven design features: Discussion possibilities; Interaction with politicians and experts; Information availability, Aim of participation; Identity verification; Anonymous participation and Accessibility. Furthermore, it is examined whether the effects differ across use of ICTs measured by generation, time online and prior use of participatory platforms. The results suggest that most design features have clear effects on evaluations, and that deliberative features have the strongest effects. Furthermore, the effects are relatively stable across prior use although the less experienced put a stronger emphasis on verification.  相似文献

Recent trends indicate a move away from self-contained classrooms and toward content-focused departmentalization in elementary schools. This study takes a snapshot of the existing organizational structures used in elementary schools in one district and explores administrators’ beliefs and practices regarding this phenomenon. Our findings suggest administrators base their decisions to organize grade levels on various factors, including their own experiences, contextual dynamics, and personal perceptions of outcomes for students and teachers.  相似文献
