Training adaptations in lower-body muscle structure and physical performance capacities of competitive surfing athletes
Get PDFThe overall aim of this thesis was to increase strength and conditioning coaches, and sport scientists’ understanding of the lower-body muscle structures related to enhanced lower-body physical capacities, and how to best evoke desirable training-specific adaptations. To address this aim, three successive steps of research were evaluated: (1) analysis of the factors related to increased performance in competitive surfing, (2) relationships between lower-body muscle structures and factors associated with enhanced physical performance, and (3) comparison of the training-specific adaptations evoked from various training methods. Whilst this research specifically focused on competitive surfing athletes, these results may benefit the training practices of athletes from a wide range of sports. The comprehensive conclusion of the research studies in this thesis suggest that competitive surfing is highly reliant on lower-body force producing capabilities, with specific vastus lateralis and lateral gastrocnemius muscle structures significantly related to these lower-body physical performance capacities. Additionally, the separation of strength and, gymnastics and plyometric training may not be best practice for adolescent athletes. However, a short duration combined strength, plyometric and gymnastics training intervention appears to provide a significant stimulus to evoke desirable adaptations in lower-body muscle structure and physical performance capacities for athletes that have limited opportunities for training between major competitions. Therefore, this thesis has provided descriptive, predictive and determinant findings associated with the physical preparation of surfing athletes, and iii therefore, provides strength and conditioning coaches, and sport scientists with an enhanced understanding of how best to evoke desirable adaptations in lower-body muscle structure and physical performance capacities
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Účinky různých postaktivačních potenciiačních zásahů na výkon rychlobruslení
Get PDF(in the Czech language) Tato dizertační práce zkoumá strategie pro zvýšení výkonu rychlobruslení tím, že se zabývá mezerami v požadavcích na trénink, metodologiích hodnocení a postaktivačním zvyšování výkonu (PAPE). Prostřednictvím tří po sobě jdoucích studií zkoumá fyziologické a biomechanické požadavky sportu, hodnotí praktické hodnocení výkonu a zkoumá konzistenci individualizovaných protokolů PAPE. Vzhledem k tomu, že se tato disertační práce skládá ze tří po sobě jdoucích studií, jsou cíle, metody a výsledky práce rozděleny do tří odlišných podúrovní (a, b, a c), z nichž každá souvisí s individuální studií. Umožňuje tak důkladné a konzistentní pochopení vědeckých metod použitých k zodpovězení zastřešujícího tématu této disertační práce. Název: Účinky různých postaktivačních potenciačních zásahů na výkon rychlobruslení Cíle: a) Provedení rešerše literatury ke zjištění současného chápání tématu a podstatných mezer v literatuře. Konkrétně jsme chtěli prozkoumat celkový vývoj rychlobruslařů na krátké vzdálenosti (500 a 1 000 metrů) až střední vzdálenosti (1 500 metrů), abychom profesionálům poskytli pochopení požadavků tohoto sportu, metod tréninku a běžná zranění. b) Proveďte studii opakovaných měření za účelem posouzení praktické aplikace profilování zrychlení na 100 metrů u závodních...Department of Biomedical Foundation in KinanthropologyKatedra biomedicínského základu v kinantropologiiFaculty of Physical Education and SportFakulta tělesné výchovy a sport
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
