Reproducibility of speed, agility and power assessments in elite academy footballers

Purpose: Fitness testing is a visible part of many youth and senior football programs (Pyne et al. 2014). A high priority is given to physical assessments that relate to the demands of match performance (Rampinini et al. 2007). However somewhat surprisingly, the reproducibility of common assessments using elite football cohorts are not widely reported in the literature (Pyne et al. 2014). Field test assessments of speed, agility and power not only provide an indicator of sport-specific power producing ability but can also be used for diagnostic purposes to identify whether an athlete is suffering from fatigue, functional / non-functional overreaching or overtraining (Meeusen et al. 2013). The purpose of this study was to ascertain the reproducibility of testing protocols used to monitor speed, agility and power capabilities within elite academy footballers. Methods: Ten male apprentice professional football players (mean ± SD: age = 17.1 ± 0.7 years, stature = 1.83 ± 0.09 m, mass: 77.8 ± 8.2 kg) participated in the study. All participants completed three separate identical trials with a day’s recovery interspersed between each trial. Each trial consisted of the following assessments; a countermovement jump test (CMJ), a seated medicine ball throw test (Throw), a 40 m run sprint test (40 m), which incorporated a 0-10 m assessed phase (10 m) and the arrowhead agility test (Agility). Results: Findings from One-way ANOVA tests indicated that performance was unchanged across the three trials for all assessments (P > 0.05). Mean typical error as a percentage (TE %) [90 % confidence intervals (CI)] across the assessments indicated highly acceptable reproducibility; CMJ = 3.2% (2.5-4.7), Throw = 1.4% (1.0-2.0). 10 m = 1.6% (1.3-2.4), 40m = 1.4% (1.1-2.0), Agility = 0.9% (0.7-1.3). Conclusion: Elite academy footballers were found to have consistent performance for assessments of speed, agility and power across three trials. Typical error was found to be low for all assessments indicating a high level of reproducibility across repeated trials (Hopkins et al. 2001). Therefore, these assessments can be confidently used in the physical fitness monitoring of elite academy footballers

Lithology and the evolution of bedrock rivers in post-orogenic settings: Constraints from the high elevation passive continental margin of SE Australia

Understanding the role of lithological variation in the evolution of topography remains a fundamental issue, especially in the neglected post-orogenic terrains. Such settings represent the major part of the Earth's surface and recent modelling suggests that a range of interactions can account for the presence of residual topography for hundreds of millions of years, thereby explaining the great antiquity of landscapes in such settings. Field data from the inland flank of the SE Australian high-elevation continental margin suggest that resistant lithologies act to retard or even preclude the headward transmission of base-level fall driven by the isostatic response to regional denudation. Rejuvenation, be it episodic or continuous, is ‘caught up’ on these resistant lithologies, meaning in effect that the bedrock channels and hillslopes upstream of these ‘stalled’ knickpoints have become detached from the base-level changes downstream of the knickpoints. Until these knickpoints are breached, therefore, catchment relief must increase over time, a landscape evolution scenario that has been most notably suggested by Crickmay and Twidale. The role of resistant lithologies indicates that detachment-limited conditions are a key to the longevity of some post-orogenic landscapes, whereas the general importance of transport-limited conditions in the evolution of post-orogenic landscapes remains to be evaluated in field settings. Non-steady-state landscapes may lie at the heart of widespread, slowly evolving post-orogenic settings, such as high-elevation passive continental margins, meaning that non-steady-state landscapes, with increasing relief through time, are the ‘rule’ rather than the exception

C.G. Jungs Rotes Buch: Visionen von Tod und Versöhnung als Kulturauftrag der Analytischen Psychologie

„I have a dream“ — gab Martin Luther King in seiner berühmten Rede am 28. August 1963 vor dem Lincoln Memorial zu Washington, DC, bekannt. Ganz ähnlich, wenn auch anders gemeint, hätte C.G. Jung sagen können, er habe einen Traum: oder besser gesagt, eine Vision? In diesem Beitrag geht es darum, die Rolle von Träumen und Visionen in der Enstehung seines Roten Buches zu untersuchen — und ihre Bedeutung zu erklären. Lässt sich das Rote Buch und die analytische Psychologie überhaupt als eine Art Vorbereitung auf den Tod verstehen? Wenn ja, dann wäre das ja nur den platonischen und neuplatonischen Wurzeln der analytischen Psychologie gerecht. Im Dialog Phaidon behauptet Sokrates im Gespräch mit Simmias und Kebes: „Alle, die sich in rechter Weise mit Philosophie befassen, haben es im Grunde auf nichts anderes abgesehen als darauf, zu sterben und tot zu sein“ (Plato, Phaidon, 64a; S. 38). Daher verdient Jungs Rotes Buch im Lichte des Kapitels „Über das Leben nach dem Tode“ in Erinnerungen, Träume, Gedanken gelesen zu werden, nicht nur weil Jung hier die Septem Sermones ad mortuos wieder aufnimmt (Jung 1974, S. 310-311) und auf eine bedeutende Weise auf die berühmte Schlussszene des Faust II anspielt (Jung 1974, S. 312), sondern weil er hier auch eine Vision der Lebensführung skizziert, die man wohl als eine Vision des gelungenen Lebens beschreiben kann

Active templates: Manipulating pointers with pictures

Active templates are a semi-automatic visual mechanism for generating algorithms for manipulating pointer-based data structures. The programmer creates a picture showing the affected part of a data structure before and after a general-case manipulation. Code for the operation is compiled directly from the picture, which also provides the development environment with enough information to generate, automatically, a series of templates for other similar pictures, each describing a different configuration which the data structure may possess. The programmer completes the algorithm by creating matching after-pictures for each of these cases. At every stage, most of the picture-generation is automatic. Much of the tedious detail of conventional pointer-based data-structure manipulation, such as maintenance of current pointers, is unnecessary in a system based on active templates
