Analysis of different key behavioral patterns to score in elite taekwondoists according to the weight category and gender

2021

Traditionally, research in taekwondo has focused on athletes' overall performance considering the entire sample of the tournament or analyzed selected bouts while ignoring behavioral differences of athletes according to their gender and weight category. Thus, the aim of this study was to analyze the behavioral patterns used to score points in the London Olympic Games according to gender and weight category [fin (FW), feather (FTW), light (LW), and heavy (HW)] of the athletes. A total of 24,940 actions were analyzed by using observational methodology, a mixed method methodology where lag sequential and polar coordinate analysis were applied. Different patterns could be seen in the actions pe…

Nietzsche o la voluntad de poder: una lectura

2018

This brief article suggests a reading of the nietzschean concept of Will to Power. First, starting from Heidegger and Deleuze¿s interpretations, an analysis on the differences between Schopenhauer¿s concept of Will and Nietzsche¿s Will to Power is developed, followed by a contrast between Nietzsche¿s Will to Power and Darwin¿s assumptions on the Theory of Evolution. Finally, Will to Power as a key concept in Nietzsche¿s ontology and epistemology is highlighted.

Semantic and perceptive organisation of Sauvignon blanc wine characteristics: Influence of Expertise.

2011

Abstract The influence of expertise on hierarchical organisation of knowledge about Sauvignon blanc wine sensory properties was investigated. Sixteen wine professionals (‘experts’) and 16 wine consumers in New Zealand organised 67 experimenter-provided descriptors of Sauvignon blanc wine by building an hierarchical tree with the sensory properties (see Urdapilleta, Giboreau, Manetta, Houix, & Richard, 2006 ). Each participant organised the Sauvignon blanc sensory properties under two conditions, a Semantic condition (memory-based) and a Perceptive condition (experiential). The Perceptive condition followed the Semantic condition and involved participants tasting three Sauvignon blanc wines,…

Virtual reality as a recovering environment - Implications for design principles

2020

In this study, a simulated, VR-based environment was built and analyzed to explore if a VR environment can possess recovering effects. 61 university students tested a VR application depicting a forest and answered survey questions about the experience. The results showed that VR-environment can indeed have recovering effects. Moreover, when comparing to previous studies in real forests, the recovery effects were at similar levels. The study results suggest that as the VR-based environments can possess recovery effects, they can work as recovery environments at schools or similar environments. The study results offer implications for the designers and propose design principles to build recov…

Tracking Changes in Frontal Lobe Hemodynamic Response in Individual Adults With Developmental Language Disorder Following HD tDCS Enhanced Phonologic…

2020

Background: Current research suggests a neurobiological marker of developmental language disorder (DLD) in adolescents and young adults may be an atypical neural profile coupled with behavioral performance that overlaps with that of normal controls. Although many imaging techniques are not suitable for the study of speech and language processing in DLD populations, fNIRS may be a viable option. In this study we asked if fNIRS can be used to identify atypical cortical activation patterns in individual adults with DLD and track potential changes in cortical activation patterns following a phonological working memory training protocol enhanced with anodal HD tDCS stimulation to the presuppleme…

Working memory (WM) performance declines with age. However, several studies have shown that WM training may lead to performance increases not only in the trained task, but also in untrained cognitive transfer tasks. It has been suggested that transfer effects occur if training task and transfer task share specific processing components that are supposedly processed in the same brain areas. In the current study, we investigated whether single-task WM training and training-related alterations in neural activity might support performance in a dual-task setting, thus assessing transfer effects to higher-order control processes in the context of dual-task coordination. A sample of older adults (…

Topical Review: Functional Anatomy of Human Hippocampal Formation and Related Structures

1996

Data on the internal organization, and neuronal connections of the human hippocampal formation and related structures of the limbic system are briefly reviewed. In the healthy brain, somatosensory, visual, and auditory input proceeds through neocortical core and belt fields to a variety of association areas, and from here the data is transported via long cortico-cortical pathways to the extended prefrontal association cortex. Tracts generated from this highest organizational level of the brain guide the data via the frontal belt (premotor cortex) to the frontal core (primary motor area). The striatal and cerebellar loops provide the major routes for this data transfer. The main components o…

Physical activity and exercise beneficially link to brain properties and cognitive functions in older adults, but the findings concerning adolescents remain tentative. During adolescence, the brain ...

Cutting Edge: An IL-17F-CreEYFP Reporter Mouse Allows Fate Mapping of Th17 Cells

2009

Abstract The need for reporter lines able to faithfully track Th17 cells in vivo has become an issue of exceptional importance. To address this, we generated a mouse strain in which Cre recombinase is expressed from the IL-17F promoter. Crossing the IL-17F-Cre allele to a conditional enhanced yellow fluorescent protein (EYFP) reporter mouse yielded the IL-17F-CreEYFP strain, in which IL-17F expression is twinned with EYFP in live IL-17F-expressing cells. Although we demonstrate that IL-17F expression is restricted to CD4+ T cells during experimental autoimmune encephalomyelitis, IL-17F-CreEYFP CD8 T cells robustly expressed IL-17F in response to TGF-β, IL-6, and IL-23. Fate mapping of IL-17…

Effects of school-based interventions on motivation towards physical activity in children and adolescents: A systematic review and meta-analysis

2020

Introduction Assuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents. Methods A comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation…
